Fun Toddler Science Activities!

1. “when will the boat sink” toddler science experiment, get your supplies ready.

Everything you need can be found with one trip around he house and shouldn’t cost any more than a few dollars if you need to grab some supplies! Here is a list of the items you will need if you don’t already have them at home.

We hope you like the products we recommend. Just so you are aware, Keep Toddlers Busy may collect a share of sales from the links on this page. As an Amazon Associate I earn from qualifying purchases. Read more about our links in my disclosure policy.

Here is what you will need:

1.Aluminum foil to make your boat

2. A Messy Mat or cardboard to catch the water. Or you can do it outside.

3. Something to weight down the boat! Coins would work great. We decided to use letter but they were a little too light. We had to add a lot of letters! The kids enjoyed it though.

Let The Guessing Began!

Have your kids guess how much it will take to sink the boat! My kids guesses were all over the place and it was hilarious 🙂

If you have more than one child, I suggest dividing up your experiment materials so everything will go smoothly! Mine argue over everything currently.

Let the Fun Begin!

This part of the activity is very simple and fun! Add each piece slowly and count them until the boat sinks! Try to spread your materials throughout the boat and you will be surprised how much can really fit on top.

The funnest part is when the boat actually sinks 🙂

We had so much fun, we had to take the party outside!

2. Glove Air Blow Experiment

We had so much fun with this!

All you need is, gloves, a cup, and a straw! I wrote names an/or alphabet letters on the fingers and I watched my kids run around blowing in their gloves saying “magic gloves”.

Check out the pictures and videos below!

Frequently Asked Questions

At what age can you start stem.

You can start exploring STEM with your child from day one. After all, we understand the world around us through STEM. All of our senses, like sound and vision, are all components of science that we experience very early on. As we get older we learn about nature and how the things around us work.

How do you teach a toddler STEM?

The best way to teach STEM is through hands on experience. Play based learning is the best approach when trying to explain concepts to kids. Keep it simple, age appropriate, and allow kids to explore and problem solve by themselves.

Do kids like STEM?

Absolutely. I have yet to meet a child who didn’t have a natural curiosity about the world around them. The key is to make it fun, without any pressure, because that is how they learn best. It’s also a great way to create toddlers and preschoolers who are intrinsically motivated to learn more.

50+ Science Experiments for 1-2 Year Olds (Toddlers)

Can you imagine! Teaching little babies’ science has become easy now.

Yes, with the help of science experiments.

I created this page to list down all Science Experiments for Toddlers (in the age group of 1-2).

I know that toddlers crave for attention and their mind is curious to explore everything they come across. Be assured, these are golden period for any kid as 80% of brain development happens below 3 years of growth. This is the right age to introduce science.

Yes, I am not joking and I have done it with my two daughters. We have collected several experiments suitable for kids of age 1 and 2. Here in this article, you will find a brief intro for the experiment and the link where you can find the detailed steps to do the activity.

Spend quality time with kids from their young age, as tender age is the right age for them to grasp things quickly.

We have crafted our toddler section having this in mind. Our activities help develop their motor skills and kindle curiosity about science. We strongly believe some of these activities will be well suited to try at your home with your little buds.

Make Observations with 5 Senses

Many of these toddler science activities below will seem more like play than learning. Truly, the best way to teach your two year old science is through play!

Encourage them to use their senses whenever possible! Make observations with the 5 senses including sight, sound, touch, smell, and sometimes even taste.

Ask Questions

Have lots of conversation with your toddler and ask questions throughout the process. Acknowledge what they have to say about the activity and try not to overcomplicate the conversation.

Ask open-ended questions without telling them what to say.

• What does it feel like? (Help name some different textures)
• What do you see happening? (Colors, bubbles, swirls, etc)
• Do you think it will…?
• What would happen if…?

This is a great introduction to the scientific method for kids!

How To Choose Science Activities

Choose a simple science activity to fit the day! Maybe you need something very playful with lots of moving around. Or maybe you want to make a snack or bake together.

Maybe the day calls for setting up a science activity you can look at over several days, and talk about together.

When introducing science to young kids, adjusting your expectations is essential…

First, keep it quick and basic with as few ingredients and steps as possible. 

Second, prep some of the materials beforehand and call your kiddo over when you are ready, so they don’t have to wait and potentially lose interest. 

Third, let them explore without too much guidance. When they’re done, they’re done, even if it’s five minutes. Just keep it fun!

I will share my favorite science experiments for toddlers below! Plus, I’ve grouped them into different sections: Playful, Make Together, and Observe. Pick one based on what the day feels like to you.

45 Easy Science Experiments for Kids

Hello, STEM! These simple DIY activities can be done at home or in school.

We've been independently researching and testing products for over 120 years. If you buy through our links, we may earn a commission. Learn more about our review process.

Imagine blowing the biggest bubbles imaginable — or even making bubbles within bubbles. Or sending vessels — rockets, tea bags, airplanes — soaring through the sky for impossible distances. Now imagine making things explode, or change colors, or reveal hidden messages with just a few simple mixtures.

First off, it's good to start them off with the scientific method. Give them a journal to record their observations, questions, hypotheses, experiments, results and conclusions. As always, safety counts: wear goggles and coats or aprons if need be (sometimes kids get a kick out of how scientific the protective gear makes them look), and always make sure that the kids are supervised when doing them. (Warning: Some of these are messy!)

These experiments are mostly designed for preschoolers through elementary schoolers — with a couple that are either demonstrations or better for older kids — but if you have a younger one, you can check out these 1-year-old learning activities , toddler learning activities and preschool/kindergarten learning activities , some of which also cover STEM subjects.

Floating Fish

Here's another one that deals with solubility and density.

• Draw the outline of a fish on the bottom of a glass plate or tray in dry-erase marker. Retrace your drawing to make sure all the lines are connected. Let dry for a minute or two.
• Fill the measuring cup with tap water. Place the pour spout just inside the corner of the dish and add water very slowly until it just covers the bottom. Be careful not to pour water directly onto your drawing or make splashes near it. The water will move toward your drawing, eventually surrounding it. Observe what happens. If the water splashes or it doesn’t work on your first try, empty the dish, erase the drawing with a paper towel, dry off the dish, and try again.
• Tilt the dish slightly from side to side. What happens? Jot it down.

The ink in dry erase markers is engineered to be slippery. It’s made with a chemical that causes it to easily release from surfaces. (Permanent markers are made with a chemical that makes the ink stick to surfaces, so be sure not to use these in your experiment!)

The easy-release ink lets go from a surface, but why does it float? There are two reasons. First, dry erase ink isn’t soluble, which means it won’t dissolve in water. Second, dry erase ink is less dense than the water, so it becomes buoyant, meaning it can float. When you tilt the dish, the fish moves around on the water’s surface.

Brush, Brush!

This one will really get them into brushing their teeth once they scientifically prove all the good things that toothpaste can do.

• Write on sticky notes: Soda 1, Soda 2, Juice 1, and Juice 2. Place them in a row on a counter.
• Fill two glasses halfway with brown soda and place behind the Soda 1 and Soda 2 sticky notes. Fill two glasses halfway with lemon juice and place behind the Juice 1 and Juice 2 sticky notes.
• Carefully place one egg in the bowl. Squeeze a big dollop — about one tablespoon — of toothpaste on top of the egg and gently rub the toothpaste all around with your hands until the egg is completely covered in a thick layer of toothpaste. Repeat with a second egg.
• Gently submerge the toothpaste-covered eggs into the liquids: one egg in the glass labeled Soda 1 and the other egg in the glass labeled Juice 1. Wash and dry your hands.
• Gently submerge the remaining eggs, without toothpaste on them, in the remaining glasses: one in the glass labeled Soda 2 and the other in the glass of juice labeled Juice 2. Wash and dry your hands. Leave the eggs in the glasses for 12 hours.
• After 12 hours, remove the eggs from the glasses of soda one at a time. Rinse them in cool water and pat them dry with the towel. Place each egg by the sticky note of the glass it was in. Are the eggs the same or different colors?
• Remove the eggs from the glasses of juice one at a time. Rinse them under the faucet and pat them dry. Place each egg by the sticky note of the glass it was in. Feel the eggs gently. Does one feel stronger or weaker than the other?
• Write down your observations in your science notebook.

The eggshells in this experiment represent the enamel (outer coating) on your teeth. Toothpaste cleans your teeth and prevents stains: it removes food and drink particles that are stuck on your teeth. Teeth can be stained easily by dark-colored liquids like cola, coffee or tea. The egg without toothpaste will be brown and discolored. The egg covered in toothpaste was protected from turning brown.

Toothpaste also protects your pearly whites from decay (breaking down). The egg without toothpaste left in the lemon juice was worn down and soft to the touch, while the egg that was protected with toothpaste is stronger. The lemon juice is acidic, and those acids broke down the shell just as acidic drinks can wear away your tooth enamel. When a tooth is worn down, a cavity can form more easily. But the fluoride in toothpaste mixes with your saliva to create a protective coating around your tooth enamel. It helps keep your teeth strong and cavity-free.

Grow an Avocado Tree

For an easy lesson in Earth Science, your family can grow an avocado tree from a pit. You can buy an AvoSeedo kit , or just peel the seed and suspend it over water with toothpicks.

Milk Bottle Xylophone

No for an experiment in sound!

• Arrange six glass jars or bottles, all the same size with no lids, in a line. What will each jar sound like when you tap it with a spoon? Make a prediction, then tap each jar. Record your observations.
• Next, put water in each of the jars. Pour 1⁄4 cup (60 ml) of water into the first jar. Add 1⁄2 cup (120 ml) of water to the second jar. Continue in 1⁄4-cup increments, adding 3⁄4 cup (180 ml) of water to the third jar, 1 cup (240 ml) of water to the fourth jar, 11⁄4 cups (300 ml) of water to the fifth jar, and 11⁄2 cups (360 ml) to the sixth jar. Add a couple of drops of food coloring to each jar.
• What will each jar sound like? Will they sound the same or different than when the container was empty? Will they sound the same or different from one another? Record your predictions.
• Tap each jar with a metal spoon. Write down your observations about each jar’s pitch (how high or low a sound is) in your notebook.

Sound waves are created by vibrations, which are back-and-forth movements that are repeated again and again. Pitch depends on the frequency of the waves — how many are created each second. A high pitch is created by high-frequency sound waves, and can sound squeaky. A low pitch is created by low-frequency sound waves, and sounds deep and booming.

When you tapped the jar, it vibrated. The vibrations traveled from the jar to the water to the air and eventually to your ears. The jars with more water had a low pitch. The sound waves vibrated more slowly because they had more water to travel through. The jars with less water had higher pitches. The sound waves vibrated faster because they had less water to travel through. A jar with no water in it makes the highest pitch because it has the least substance to travel through.

"Elephant Toothpaste"

Okay, elephants don't really brush with this stuff, which is made from a chemical reaction between hydrogen peroxide, yeast, dish soap and a few other simple ingredients. But this experiment has a big "wow" factor since, when the substances are mixed, the "toothpaste" foams out of the bottle. You can use it to teach kids about catalysts and exothermic reactions.

Paper Bridge

Get the engineering back into STEM with this activity, which challenges kids to create a paper bridge that's strong enough to hold as many pennies as possible. How can they manipulate the paper to make it sturdier? (Hint: Fold it!)

See the paper bridge tutorial at KidsActivities.com »

Challenge your little scientist to lift up an ice cube with just a piece of string. It's possible ... with a little salt to help. Salt melts the ice and lowers the freezing point of the ice cube, which absorbs the heat from the water around it, making the water cold enough to re-freeze around the string.

Coin Inertia

Stack up about five or so coins on a piece of cardboard and place it over a glass of water. Then, flick the cardboard out from on top of the glass. Do the coins drop into the water, or ride with the cardboard? Due to inertia, they drop into the water — a very visual (and fun!) demonstration of Newton's First Law of Motion.

Apple Oxidation

What works best for keeping an apple from turning brown? Test to find out! Slice up an apple, and let each slice soak in a different liquid. Then take them out, lay them on a tray, and check the brownness after three minutes, six minutes and so on. Not only does this test the properties of different liquids, it also helps students practice the scientific method if they create hypotheses about which liquids would be most effective.

Chromatography Flowers

Chromatography is the process of separating a solution into different parts — like the pigments in the ink used in markers. If you draw stripes around a coffee filter, then fold it up and dip the tip in water, the water will travel up the filter and separate the marker ink into its different pigments (in cool patterns that you can display as a craft project). This family made the end-result even brighter by adding an LED circuit to the center.

10 quick and Easy science experiments for toddlers that are totally awesome {2 years old and Up}

It is science week here at Tot School, and to celebrate, we had a week full of daily science experiments for toddlers.

If you are looking for easy science experiments for toddlers to learn and enjoy, these are our top favorites so far!

All of these science experiments for toddlers are age-appropriate, fun, and have been tested and approved by my own toddler 2-year-old toddler as well as my sensory students.

The Best science experiments for toddlers

#1 volcanic eruptions.

Also called witches brew. This science experiment for toddlers come in as number 1 in our list because it is so easy to make, it is so much fun to do, and the kids can do it themselves.

To do this experiment, all you need is some baking soda and vinegar. The mixture between the two created a magic explosion that is safe for the little ones and a lot of fun.

Use food coloring to change the color of the bubbles. Add water to the vinegar to dilute and expand the use of it, the kids love to pour and see the bubbles repeatedly, so this will extend the activity for extra playtime.

Learn how to set up this witches brew experiment with step by step instructions

#2 fizzy cubes.

To make fizzy cubes freeze a mixture of baking soda and water. Activate with the vinegar the same way mentioned above.

To change the activity and work fine motor skills , this activity was set up using a dropper to suck the vinegar and squeeze it into the fizzy cube.

My toddler tried it a few times but wanted a faster way to dissolve the cubes. He enjoyed grabbing each of the fizzy cubes and dropping them into the vinegar cup.

Making Oobleck is one of my favorite activities, but it can get very messy! When you grab this substance, it is solid, but it melts and becomes liquid when you let go of the pressure.

To do this science experiment all you need is two parts cornstarch and 1 part water.

Watch our quick video or get the step by step instructions and learn how to make oobleck

View this post on Instagram Make the coolest science experiment for toddlers and am kids of all ages. All you need is water, cornstarch and food coloring. (Be careful as some food coloring can temporarily stain the hand) 1 cup of water to about 2 cups of corns starch A post shared by Alexa | Kid Activities (@kidactivitieswithalexa) on Jul 15, 2020 at 6:38pm PDT

#4 Sink or Float

Understanding weight is one of the first science experiments that you can do at home. All you need is a bowl of water and a few water-safe objects.

Start by identifying what happens when each objects touches the water. Repetition here is key!

Once tout toddler grasps the new vocabulary words and correctly identifies what is happening then try to ask before the item gets dropped to guess what he thinks is going to happen.

You can repeat this experiment during bath time, at the pool or anywhere you have access to water.

Have you played the sink or float game? Well, actually is a science experiment and one of our favorite activities. I usually let Manu set up the whole thing form the beginning. I give him a pitcher of water and an empty bowl for him to pour h the e water into. Then we walk around and find different things to test out. Will it float? Will it sink? I let him pick what he wants to throw (as long as it can get wet and has no batteries) and this freedom lets him explore and learn. Who knew a bowl of water could be so fun! #2yearoldactivities #toddleractivitiesathome Posted by Kid Activities with Alexa on Monday, September 28, 2020

Learn how to set up the sink of float experiment with step by step instructions

#5 hot and cold.

Learn about temperature using sensory bottles. We filled out one bottle of water with cold water and added a few ice cubes and filled out a second one using hot water. We dyed the cold water blue and the hot water yellow to help associate the concepts.

We also paired this opposite lesson with a YouTube video which we learned the lyrics and acted out the finger-play actions throughout the week.

#6 mixing Colors

Once a toddler is familiar with the colors, can identify and name them correctly it is time to add colors into science experiments. Working with primary colors we have started to create a few experiments to make new colors. This week was all about yellow and blue makes green. We did it with some water, food coloring and soap as well as with paint.

What Primary colors make new colors?

• Red and Yellow makes Orange
• Yellow and blue makes Green
• Blue and Red makes Purple/Voilet

Discovering air is one of the very first science concepts that can be taught, Do this experiment if your child knows how to blow out already. Add a squirt of dish soap into a bowl and some water. Provide a straw and show your toddler how to blow to create bubbles.

Look at the colors the bubbles reflect, can you hold it? does it pop? can you blow on them? what happens?

As a variation of this experiment, you can add watercolor paint to the solution and allow the colored bubbles to pop into a paper to create a work of art.

#8 DIY Lava Lamp

This experiment was one of Manu’s favorite. To create your own DIY lava lamp you will need vegetable oil, water, food coloring and effervescent tablets.

For our first try we filled out 1/2 of the glass cup with water and added food coloring (too much!) and the other half with vegetable oil. I crushed the effervescent tablet in many pieces as I knew my toddler would enjoy dropping them tablets into the glass.

Once the tablet hits the water, it starts to dissolve and create bubbles who travel upwards on the glass, passing through the oil and popping into the surface. Because the water doesn’t mix with the oil, you can visually see how these bubbles travel towards the surface and once they pop how the water travel back down.

For our second try, we did only 1/4 of water and used a lot less food coloring and added a lot more vegetable oil to the glass. The lava lamp looked a lot better as the colored water bubbles had more room to travel.

Cutting up the tablets in different pieces was a great ideas. Manu loved creating the bubbles and enjoyed repeating it over and over.

Slime is a great tool to work on fine motor skills, it is also a cool chemistry experiment. Similar to oobleck, slime changes is composition when played with. It is solid but stretches or breaks. For toddlers, of course, they won’t really understand the science concept behind it but they will enjoy playing with the material and making their own little experiments as they learn and understand how slime behaves. Is not like playdough, it is not like oobleck, it is its own unique material.

I like to use fluffy slime , like the rainbow slime or the white fluffy slime with toddlers. Fluffy slime is less stretchy that other types so it is easier to handle by toddlers.

Learn how to make white fluffy slime.

#10 Exploring light

Learning about light and dark, shadows and reflections are all science activities you can start exploring early on.

Make shadows using cutout woods or use your hands and a flashlight, use the sun to explore the light and it’s reflection. We have done colored bottles to explore the colors reflect on the floor, made apple shaped suncatchers and made a glow in the dark sensory bottle.

Last Thoughts

Science can be a lot of fun and as you can see, you can start even when they are toddlers. Allowing your toddler time and exposure to different materials and experiments helps them understand the world they live in, gives them the confident to experiment and explore and gain a ton of new information when doing so. Don’t forget to always supervise any experiment or invitation to play.

Science Experiments at Home that take Less than 1 Hour

1. tie-dye milk.

Sounds delicious, right? You’re not actually drinking it, but instead watching science magic happens when you combine dish soap with milk and food coloring. This is a very pretty experiment that draws the focus and mind into what’s happening on the plate, and all because of a little chemistry with everyday items. Well, food dye may not be an everyday item, but it might be after your kids get a hold of this!

So, what’s going on here, scientifically-speaking? Milk is made up of two major ingredients: water and fat. When you add a little dish soap, it bonds with the fat in the milk so strongly that it literally pushes the food coloring and water away from the cotton ball. On a microscopic level, the dish soap is wandering around the milk, which causes the colors to swirl and swirl.

Questions to ask beforehand:

• Before knowing what will happen to the food coloring, ask the kids what they think will happen when dish soap mixes with milk.
• Since the major catalyst is fat in the milk, what would happen if you used other types of milk: Skim milk, soy milk, coconut milk?

You’ll need:

• Round cake pan or plate with high edges
• Cotton ball (some tutorials show cotton swabs)
• Dish detergent
• Different colors of food dye (three or four should do)

Procedure/Instructions:

• Fill the pan halfway with milk.
• Drip one color of food dye in one section of the plate away from the center. Four to five drops works and later you can play around with more or less. Do the same for the rest of the colors around the plate.
• Soak the cotton ball in dish detergent, and when you’re ready for action, place the cotton ball into the center of the pan.
• Watch the colors racing around, creating a psychedelic tie-dye effect!
• You can add more cotton balls throughout the dish to see more action.
• If some food coloring hugs the wall of the plate, take a cotton swab dipped in dish detergent and place it into the food coloring. It will move away!

2. Saturn’s Glowing Rings

I don’t know about you, but I love everything about space. This experiment shows you how Saturn’s rings are made of rocks and ice chunks even though they look so smooth in pictures. You’ll also see why there are big gaps in the rings. Younger kids take delight in using a flashlight and sprinkling powder, while older kids can get more specific with questions about Saturn and how the rocks and ice stay in orbit.

• Do Saturn’s rings give off their own light?
• Why are some rocks and ice chunks more lit up than others?
• Compare the results of light sprinkles to thicker sprinkles.
• Strong flashlight
• Powder (flour, baby powder, etc) in a shaker
• Very dark room
• Darken a room and set the flashlight on the edge of a table or counter, pointing it at a blank wall. Lay the newspaper on the floor between the flashlight and the wall.
• Turn on the flashlight and notice where the light comes from the flashlight and where it hits the wall. You should only see the light from these two places and not from the space between them. This shows you that the light travels through the air without being seen until it hits the wall. The light represents the sun’s light.
• Now to see how Saturn’s rings glow: Hold the powder shaker and sprinkle some powder over the beam of light where you know the light is traveling. You’ll notice the powder lights up and sparkles in the beam of light. The powder shows in glowing clumps, just like in Saturn’s rings.

3. Breaking Down Colors

We all know that the fun, vibrant colors we see in our lives are created by mixing the basic red, yellow, and blue. In this experiment, you and your child will learn which colors make up those fun shades they have in their art supplies. This also teaches some basic chemistry and uses materials you already have at home. It can be done very simply and expanded to create a large-scale investigation if you love it.

• Which colors separate out first?
• Is the same order for each test?
• Which colors make up the original shade?
• Do the different types of color (pen, pencil, paint) separate in the same way or differently?
• Are some separated in a shorter space are the colors the same mixture?
• Coffee filters
• Color sources (markers, colored pencils, paint, etc.)
• A plain pencil
• To complete this experiment, cut the coffee filters into strips, mark one end with a line the same distance from the bottom on each strip.
• Color in each strip (between the bottom and line) with your colors, and write at the top what the color and source are (e.g., purple marker).
• Place each strip in a glass and help it to stand up by folding the top over a pencil (a chopstick, table knife, or any long narrow object will also work) so that it stands up in the glass.
• Fill the glass up to the top of your colored block, and wait. The water will move up the filter, and the colors will separate out as it goes.
• Remove the strip once the water gets near the top of the strip to stop the experiment. 

To make this a true experiment, we recommend testing multiple colors and using markers, colored pencils, and paint (as some starting examples). You could test the same colors from each type of art supply to investigate whether they all use the same mix of basic colors to create the same end product.

This post has a nice full description of the methods if you need more detail.

4. Water Xylophone

This simple experiment will teach your child about sound and pitch using glasses, water, and something to act as a mallet. Don’t let the simplicity deceive you, there are a lot of ways to experiment and learn through this process, and it also brings in an element of music that makes it interesting and engaging.

• Do you think more water makes the sound higher or lower in pitch?
• How do you think the shape or size of the glass will affect the sound?
• How should we arrange the glasses to play a simple song?
• Do you think this will work with a plastic cup, why or why not?
• Some glasses
• Something wood to act as a mallet (we recommend wood so you don’t break the glasses!)
• A great way to start is with glasses that are the same size, shape, and material, and filling them with different amounts of water.
• Have your child use the mallet to test how the amount of water affects the sound.
• From there, it’s a really simple extension to use different sized and shaped glasses (or any glass vessel like jars and bowls) to experiment with how the shape, size, and amount of water in the glass affect the tone. 

To take this one further and really bring in the musical component, you and your child could work out a simple song and create the right tones to play it. If you or your child are musical, you could get very elaborate and creative (try googling harry potter or star wars theme songs on glasses, there are so many options that I couldn’t even choose one)!

5. Ultimate Bottle Flipping

Ah, bottle flipping. The fad that kids can’t get enough of, but parents are well and truly over. The constant thud of semi-filled water bottles being tossed (and hopefully landing upright) is guaranteed to send parents around the twist!

If you can stand it for a bit longer though, there’s a lot of STEM knowledge to be gained in this bottle flipping experiment. As we know, the aim of bottle flipping is to flip a partially filled water bottle underhand and get it to land upright.

In this experiment, kids will learn the importance of observing a result multiple times before changing a variable (the amount of water in the bottle).

• How much water should you put in the bottle?
• What is the ideal amount of liquid to get the perfect flip?
• What should be the ideal amount of water?
• Was their prediction correct?
• Why do they think the amount of water affects the chances of landing the bottle?
• A plastic water bottle
• Measuring jug
• Paper to record results
• Get the kids to start by flipping their bottle with no water in it at all. Kidspot recommends flipping it 50 times for each step, but you could do less if you need to.
• Try it again with 50ml of water.
• Keep adding more water until the bottle is full.

If they’re keen, you could try other types or sizes of bottles, or even try different liquids to see if that affects the results!

6. Rainbow in a Jar

This simple science experiment is not only very visually appealing, but it’s also a great way to learn about the density of liquids. Warning though, this one could get messy so make sure kids are in some old clothes and you might want to take it outside! I like this experiment because you’ll probably have most of the materials in your kitchen already!

• Which liquids they think will be heaviest?
• Which ones will be lightest?
• Why do they think that?
• A glass jar
• Food coloring
• Various liquids like honey, corn syrup, dishwashing liquid, olive oil, rubbing alcohol and water.
• Use the food coloring to make all your liquids a different color. A dropper comes in handy here, but if you don’t have one you can manage without.
• Slowly add each liquid to the jar (pouring into the middle of the jar is best).
• Soon, you’ll have different layers of colored liquid forming your very own rainbow in a jar.

You might even get them to draw a diagram of what they think the jar will look like at the end. They can compare this with the experiment results to see if their prediction was correct.

It might also help to talk to your kids first about what density is and how materials are all made of different amounts of molecules. The more molecules a liquid has, the heavier it will be. Playdough to Plato demonstrates a great way of introducing this concept using marbles. 

7. Write Your Own Secret Messages! 

We love science experiments that are made up primarily of supplies that you likely already have in your home.

• Why do you think this will work?
• Which liquid do you think will make the best secret message?
• Why do people write secret messages?
• Juice (eg. Lemon)
• Lamp (or anything else that can be used as a heat source)
• In order to complete this experiment, you’ll need to gather all of your supplies along with a piece of paper, some q-tips, and a lamp or other item that you can use as a heat source.
• Next, you’ll mix your lemon juice with a slight amount of water. 
• Using your q-tip, use the mixture you’ve created to begin writing your message. 
• Allow it to dry. 
• Once dry, apply heat to it in order to get your message to appear.

Extend this project by attempting to write with a juice and water mixture, a milk and water mixture, or any other variation of the liquids we listed as necessary supplies!

8. Create Your Own Butterfly

Your little ones will love practicing their color mixing by creating their very own coffee filter butterflies. Hang them in the windows of your home to spread some cheer and to watch the sun flow through their beautiful wings! 

• What colors can mix together to make other colors?
• How do butterflies fly?
• What do you think will happen when we add water to the markers?
• Water spray bottle
• Allow your child to draw on the coffee filter to their heart’s content.
• Spray it with water and allow the colors to mix together.
• Allow it to dry thoroughly.
• Once dry, fold it like a fan and then clip it in the middle.

Ta-da, you’ve created a beautiful butterfly! 

9. Make A Duck Call

Give your family an excuse to head outdoors by allowing your children to craft their own duck calls. Test them out at a local pond and see if you can get the ducks to come closer to you for a healthy veggie snack! 

• Do you think ducks will be able to hear us with this?
• What other materials do you think could make this noise?
• How is what we have created similar to a duck’s beak?
• Plastic straw
• Push down on the straw to flatten one end and then cut the flattened end into a point.
• Flatten out your straw and then blow into it.
• Feel free to experiment with different amounts of flattening and different point shapes to see how you can adjust the sound.
• When finished, take your duck call into the wild to test it out.

10. Make Ivory Soap Boats

Did you ever carve items out of soap at camp when you were a child? Give your child the same opportunity. Soap can be carved using safe items, like plastic knives. 

• Why are we able to carve soap so easily?
• Do you think our boats float?
• Why do you think they float or sink?
• Carving tools (for kids)
• Allow your child to express their creative side by carving their boat out of soap. 
• Once they have finished carving it, allow them to test them out in the bathtub. . Extend their learning by discussing density with them–the soap floats because it is less dense than the water.

11. Make Your Own Quicksand 

As John Mullaney famously said, “I thought quicksand would be a much bigger problem in my adult life than it would have turned out.” For some reason, quicksand permeates children’s adventure stories – and their imaginations! 

• Where can we find quicksand in real life?
• How do you think quicksand works?
• What do you think we will need to make our own quicksand?
• Cornflower (one cup)
• Water (half cup)
• A container
• To make your quicksand, you’ll need to mix the cornflour and water. 
• Be sure to stir slowly in order to demonstrate – if you stir too quickly, it will become hard and you won’t be able to see it function the way it should!

12. Make Your Own Lava Lamp

We’ve tried this one in our classrooms, and trust us, our kids go wild year after year. Kids love making something that they can use as home decoration, and they love how easy it is to show new people – this is the experiment that lives on and on! 

• How do you think density is involved in this experiment?
• Why don’t the water and oil mix?
• Why can’t we shake our lava lamps?
• Clear Plastic Bottle
• Vegetable Oil
• Food Coloring
• Alka-Seltzer
• Pour water into the plastic bottle until it is approximately one quarter full. 
• Then pour vegetable oil in until the bottle is almost completely filled. 
• Allow some time for the oil and water to separate. 
• It is important that your children do not shake the bottle in this step. It will extend the experiment for no other reason than you waiting for the bubbles to dissipate. 
• Add as much food coloring as your child deems fit and then drop a piece of Alka-seltzer tablet into the bottle for the lava lamp fun to begin.

13. Guess the Smell

This one will take a little more prep work, but it’s a great touchstone for your children to begin discussing one of their five senses: the sense of smell! 

• What are examples of times we use our sense of smell?
• What other senses do we have?
• If you could only use one sense for the rest of your life, which one?
• Plastic Cups
• Smells (eg. coffee, cinnamon, vanilla, lemon juice)
• Place a variety of common smells in small plastic cups. We like to use coffee, cinnamon, vanilla, and lemon juice. 
• Pour these in and place tin foil securely over the top of the cup. 
• Poke small holes in the top of the foil. 
• Secure the foil with tape (on the sides, not over the holes). 
• Allow your children to guess the smells and record their findings on paper.

Home Science Experiments that take 1 to Several Hours

14. mangrove bioshield  .

Ecologists and conservationists are pushing for more regulations in building and saving mangrove forests around coastal areas. The reason is represented in this STEM activity. The trees act as a mangrove BioShield (bio = life, shield = protection), showing how natural obstacles can prevent critical damage from marine natural disasters such as tsunamis.

The mangrove BioShield can be for older elementary kids through to high school. Obviously, the younger they are, the more parent involvement. This experiment is done twice to show the effects of having and not having a BioShield. The first part uses little to no trees, and the second uses a forest of trees and rocks.

• What will happen in a tsunami if the village is without a BioShield? And the village with a BioShield?
• Would a BioShield help with hurricanes?
• Would you want to encourage people to save manatee forests if they are beneficial?
• Medium to large clear, plastic container
• Newspaper – wad into balls, then cover half of the bottom container – this help to keep the ground sturdy
• Mud – cover the newspaper and press it in to form a slope down to the empty side of the container. The top side should be flattened for the cardboard houses, then it slopes down into the empty half of the container.
• Cardboard houses (use the bottoms of milk cartons for the house and popsicle sticks for the roofs, place houses on the mud towards the top of the high slope
• Model trees or leafy stems from plants – Different amounts for activity 1 and activity 2
• Several small rocks
• Cardboard – long enough to fit across the container and tall enough to hold it from out of the water
• Water – enough to go halfway up the slope

A tsunami without the mangrove forest – insert only one or two trees down the slope. Place the cardboard piece into the water end of the container and move back and forth to create waves. Notice how easy it is for the water to destroy the village you’ve created.

Repeat the process of constructing the village, but this time insert a lot of trees down the slope to where the water meets the mud. They need to be deeply rooted like mangroves, and I’ve found that aquarium plants work well for this reason. Place the rocks within the mangrove forest and in front of the trees. Add a little bit more water. Insert the cardboard again and move it back and forth to create waves.  

15. A Greater Crater

When you look at the night sky and see the moon, one of the first things you notice is its craters. The moon is completely covered in them, and some are so large we can see them from Earth. Meteorites often make the craters that we see when they hit the surface, but it makes us wonder why some craters are so much bigger than others.

This experiment will help you to investigate one of the main reasons why craters come in different sizes.

• What causes craters?
• How big do the meteorites have to be to make a crater?
• What is it about the meteorite that causes the size of the crater?
• Paper to record your results
• Flat floor surface for the experiment, large enough for the newspaper to cover
• Shallow metal pan at least 2 inches deep
• Flour to fill 2 inches of the pan
• ¼ cup hot chocolate powder
• Mesh strainer or flour sifter
• Large marble (and others of varying sizes if comparing results)
• Metric ruler
• Tongs or long tweezers
• Pour the flour into the pan until it reaches 2 inches. Place the pan on top of the newspaper on a level surface.
• Sift a layer of hot chocolate powder over the flour (this is so you can better see the rays and other features of the craters).
• You will be dropping your marble from three different heights, then comparing the sizes of the craters. Measure the diameter (side to side) of the marble and record this on your paper as Marble 1. Hypothesize how large the crater will be and write that next to the diameter of Marble 1.
• Stand next to your pan and hold the marble at knee height above the flour. Drop the marble (do not throw it, just let it fall from your fingers) into the flour and study the shape of the crater. Look for a rim around the crater or any rays coming from the edges.
• Measure across the widest part of your crater, from rim to rim and record on your data sheet as Marble 1 – Knee Height – Width or something similar. You can also draw a picture of your results.
• Very gently use the tongs or long tweezers to remove the marble without destroying the crater.
• Repeat this procedure from waist height, shoulder height, top of head height. Make sure you aim in different parts of the flour so you don’t land on top of another crater. Record all of your results as the different heights you’re using.
• Compare your results.
• You can try again with a different sized marble as “Marble 2” to compare those results with each height as done with Marble 1.

Perhaps now, you’ll look at the moon a little differently!

16. Rube Goldberg Chain Reaction Machine

We’ve all seen them, some pretty far-out there chain reaction machines to complete simple tasks, usually in movies. But they are real , and are becoming even more popular now that we’re all stuck at home for a while. This is a fun way to explore physics with stuff you have at home.

Ask your child to decide what the end goal is (e.g. get the ball into the cup), and ask them to think about creative ways to make it get there. Working together, you can start with small pieces of a circuit to find out how your ball reacts to the set-up, and grow it from there. You can even refer to this video for more ideas:

• What will happen when the ball bounces off of this wall?
• How will these dominoes change the speed of the ball?
• What can we use to make sure that the ball goes in the direction we want it to at this point?
• What should we put here to get the best bounce? 
• Paper towel
• Toilet paper tubes
• Fixed objects like walls or furniture
• Any other toys and materials that can be used to build your circuit

To make this a true experiment, it needs to include more than a one-off demonstration, and there are a lot of ways to accomplish this.

• Set up parallel courses and use different sized or weighted balls to go through the circuit.
• Set up one elaborate circuit and use different objects one at a time.
• Set up circuits in different ways to see how different set-ups affect your end goal.

Another experimental component is the process used to create a circuit that reaches your end goal ( like this video about getting the ball into the cup, but you could come up with lots of other endpoints!). Along the way, you and your child get a lot of time to learn about momentum, velocity, friction, energy transfer, and interference (e.g., the cat). 

17. Melting

This is a simple and fun experiment that can be set up in a short time and then fill-up your day with observations and new experiments. Using only things you already have at home, you can set-up an engaging experiment with your kids!

Ice melts at different rates depending on a variety of factors including temperature, pressure, and if there are impurities (think salt, sugar, dirt) in the ice or touching the ice. There is a lot of opportunities to get creative and do the experiment in multiple ways, keeping your kids engaged and developing their investigative, experimental, and critical thinking skills.

• Which ice melts the fastest, slowest, and if they have any guesses about why?
• What other ice-melting experiments they think would be fun: Using different temperature liquids? Using different amounts of ice? Different sized cups?
• Lots of ice
• Several matching cups (i.e., they are the same size, shape, and color)
• Measuring cups
• A variety of liquids for the test
• Paper for writing down observations
• Measure the same amount of ice and place it in each cup.
• M easure equal amounts of each liquid and place them in the cups: try to complete this part quickly so that the ice in each cup is in liquid for as close the same amount of time as possible.
• Set up your cups in a place that is easy for your child to watch and observe.
• Ask them to check in at regular intervals (every 15 minutes, every hour) and record or talk to you about their observations.

Other potential experimental examples:

• Using different liquids to test if they affect melting time;
• Using the same liquid and placing ice in different locations to test what conditions throughout your home affect melting;
• Test if different amounts of ice melt at different rates;
• Test if different kinds of cups change melting time.

There are endless possibilities for you to come up with new ways to complete these simple experiments. You get the idea. Explore more!

18. Breathing Leaves

Science experiments don’t get much more simple than this one!  It’s effective though and kids will enjoy watching their leaf ‘breathe’. Learning about plant science is often tricky because it can seem a bit abstract. This experiment allows kids to see the process of plants making oxygen right before their eyes!

A question to ask beforehand:

• What do you think will happen if we leave it for a few hours?
• A fresh leaf from a tree
• A bowl of water
• Pluck a fresh leaf from a tree and place it in a bowl of water.
• Use a rock to weigh it down and leave the experiment out in the sun.
• Have your kids predict what they think they will see when they come back in a few hours (they can write their prediction down or draw a diagram if that’s more their style).
• After a few hours, your kids will see lots of tiny little bubbles on the edge of the leaf and in the glass bowl of water (use a magnifying glass to get a closer look if you have one).

So, what’s happening here? Leaves take in carbon dioxide and convert it to oxygen during photosynthesis. The bubbles you can see are the leaf releasing the oxygen it’s created. You could explain to your kids how trees and plants make the oxygen we need to breathe. Kids Fun Science explains this experiment in more detail and suggests taking it further by leaving the plant for a longer period of time (do you see more or fewer bubbles?) or placing a leaf in a dark area to see what difference that makes!

19. How Does Sunscreen Work?

If there’s one thing I know, it’s that kids hate wearing sunscreen! Trying to get it on them is like wrestling a crocodile. Maybe if they knew how sunscreen worked they’d understand how important it is to wear it when they’re out in the sun (and be slightly more cooperative when we’re lathering it over their little faces). This is a simple experiment that shows kids the difference wearing sunscreen will make to their skin.

• What do they observe when they come back?
• Why do they think one side faded and the other not?
• A piece of colored cardboard (a dark color would be best)
• Your usual bottle of sunscreen
• Have your kids smear the sunscreen over one part of the cardboard and leave the other part clear.
• Kids can then predict what they think will happen when they return to the experiment after a few hours.
• Talk to them about how the sun’s UV radiation is absorbed by the sunscreen so it can’t get through to damage the cardboard.

You could even take it further by trying different kinds of sunscreen or leaving your cardboard out during different times of the day.

20. Make A Rubber Egg

Imagine a world in which eggs can be used like bouncy balls. Well, with a couple of home supplies and a little bit of science, you can live in that world. Your child will be dazzled as they remove eggshells from eggs while leaving the insides intact. 

• Is vinegar an acid or a base?
• Is there another substance that could do this?
• Simply leave the egg in the vinegar for a few hours and wait to see what happens. Because of the transformative nature of this experiment, it lends itself to science journaling. 
• Consider having your kiddos draw before and after pictures of the eggs in order to track their journeys. 

21. Flying Tea Bags

Nothing will get your kids’ attention faster than telling them that you are going to spend some time creating something that will fly. However, because this experiment will involve fire, please ensure that you select a time in which you will be able to provide ample adult supervision. 

• How do we stay safe with fire?
• How do we make sure we don’t damage the surface we are working on?
• Why do you think the tea bag will fly?
• Single Serving Tea Bags
• A Small Bowl
• A Non-Flammable Work Surface
• First, open the tea bags and unfold them. 
• Empty the leaves from the bag. 
• Stand the tea bags up on your surface and light the top of each bag on fire. 

As they begin to burn, they will float into the sky! 

22. Make Wax Paper Lanterns

Your children will love the chance to display their fantastic art skills by creating these paper lanterns. If you want to add a culture lesson, have your children research German’s St. Martin’s Day and learn about why children parade through the streets with lanterns. We promise there’s a good moral story involved here! 

• When could we use lanterns?
• What safety considerations do we need to use in this project?
• Why can we see the light through the wax paper?
• Popsicle Sticks
• To begin, tear a ten-inch piece of wax paper off of the roll and cut it in half. 
• After that, fold each piece in half. 
• Allow your child to color their image on top of the wax paper. (This is a great place for an impromptu lesson in color mixing). 
• Fold the wax paper and iron it (consider something in between the crayon mess and the iron you use on your clothes). 
• Finally, glue the craft sticks into squares, add the wax paper, and turn it into a cube.

Voila, you’ve created your own lantern!

23. Create an Insect Habitat

Alright, this one isn’t for the faint of heart. Draw up your courage and send your child into the backyard to collect all of the creepy crawlies they’d like to.

Now you have a home for them. Better yet, you can keep your child entertained for hours as they track the growth of their bug friends.

• What do bugs need to survive?
• What do bugs eat?
• What is the difference between a need and a want?
• Imagination
• Find something that you’re willing to sacrifice to the bugs in order to create a habitat for them – we recommend a shadowbox so that your child can see inside, but a cardboard box will do just fine as well. 
• Ensure that there is breathing room for the bugs. 
• Create a habitat with sticks, bark, small rocks, dried leaves, and whatever else you can find.
• If you’re willing to hang onto the habitat long enough, use it as an opportunity to talk about decomposition as the bugs begin to break down the twigs.

Long-Term Science Experiments at Home

24. crystal kingdom.

This is the oldest trick in the book, but it’s popular because it’s so effective, fun, and has great results. The only drawback to most crystal-growing recipes is that they take ages to grow, and to be quite honest this one is no exception. In fact, these crystals will take several days to grow but the end result is worth it. The reason is that this experiment involves growing a whole landscape of beautifully colored salt and bluing crystals. Here’s a video for visual reference: 

A few things to keep in mind: Allow for plenty of air circulation, preferably inside rather than outside. Ammonia is not necessary but does help in the process.

• What will happen when you add ammonia?
• Why does more salt and less liquid create faster crystallization?
• What part does the bluing solution have in crystal growing?

(Answers can be found here )

• Two bottles of bluing solution
• Large tray/cookie sheets with sides
• Measuring cup
• Liquid watercolors
• Eye droppers
• Cut sponges into large pieces. Spread them out on the tray.
• Measure out 1 cup of each of salt, water, and bluing and then gently mix together.
• Evenly coat or sprinkle the mix over the sponges.
• Add 1 cup of ammonia to the sponges.
• Coat an extra 1 cup of salt on to the sponges.
• By now you’ll see some crystals growing . Sprinkle the magic mix again: 1 cup each of salt, water, and bluing. You can pour the ingredients onto the tray instead of on top of the crystals to keep them from breaking. Don’t worry, more will grow!
• Take an eyedropper, and drop a tablespoon of each liquid watercolor (undiluted) in different patterns over the sponges and crystals.
• Take note of your garden and what the crystal formations look like. You can make a sketch in your notebook as a before and after. Ask questions and observe!
• Observe how the crystals are bigger than before, and notice the colors aren’t as vibrant. Compare the differences in shapes, sizes, and colors.
• If you want more crystals to grow, add a little more water, bluing, and salt.

25. Blow up a Balloon with Yeast

We are surrounded by science in action, but sometimes it is really difficult to see what is happening, especially when it is on a small-scale. When we make bread, yeast ‘eats’ the sugars in the food and creates CO2, giving bread its airy texture. This experiment lets you both visualize what happens when yeast consumes sugar and is a great set-up for an experiment that can be observed throughout the day.

Depending on your supplies and time, you could start with a demonstration and use that to think of other tests, or you could set up several parallel tests at the same time.

• How quickly does the balloon filled with air?
• When does it stop filling (at some point the yeast will run out of food and will stop making gas)?
• Does the starting temperature affect the experiment?
• Does the balloon fill faster in different places in your home (try especially for different air-temperatures, you could include an outside location)?
• Some balloons
• Blow up the balloon a few times before starting so that it’s loosened up a bit.
• Fill the bottle with about 1 inch of warm water (heat is required to activate the yeast, but you could experiment with different temperatures), add the yeast and swirl to dissolve.
• Add the sugar and swirl more.
• Place the balloon over the opening to the bottle and wait. You should expect to see the balloon begin to inflate after around 20 minutes.
• Continue checking and observing how much the balloon inflates throughout the day.

More example experimental setups include:

• Do different temperatures – either with the water you start with or the air the yeast lives in – affect how quickly the balloon blows-up?
• Does using 2x the yeast result in a balloon that is 2x bigger, or blows-up 2x faster?
• Do different types of sugar (e.g., white sugar, honey, syrup, flour) affect how quickly the balloon blows up or how big it gets?

A sk your child to think of new experiments (you could prompt with some of the examples above, or ideas from this post ). 

26. Seed Germination

A really simple but fun multi-day experiment is germinating seeds under different conditions. This means finding some quick-sprouting seeds such as beans and putting them in different conditions to see how that affects germination (sprouting leaves and roots) and growth.

I love using seed experiments because they are inexpensive, simple, and leave a ton of room for creating your own unique experiment.

• Which seed will sprout fastest?
• Seeds (Beans, radishes, squashes, and many flowers sprout quickly from large seeds, making them good choices.)
• Small pots or paper cups
• Potting soil
• Cloth or paper towel
• Somewhere with good light
• To get started, you’ll need some seeds – feel free to choose something you already have, if you’re a gardener you might have some seeds ready for the coming season and could spare a few – or find something online or at your local nursery.
• Use small pots or paper cups and fill each with your growth material (we recommend a minimum of 3 for a useful comparison).
• Fill one with potting soil, one with sand, and one with a cloth or paper towel.
• Place them somewhere with good light, and add water.
• Ask your child to predict which seed will sprout fastest, and make observations every day. If possible, make them around the same time each day.
• Once you see growth, you can ask your child what they think caused any differences, and you can use that as a jumping-off point for more experiments

Additionally, you could:

• Use one type of seed and different types of growth media: soil, paper towel, gravel, sand, water, etc.
• You could use different seeds (beans, flowers, grass, herbs) and grow them under the same conditions (soil, water, sun exposure) to see how different plants grow differently.
• You could see how different light conditions (by a window, in the basement, in a bright room away from a window, etc.) affect germination.

You could also extend each experiment by simply continuing to grow each seed to learn whether the different germination time affects long-term growth (you may want to re-pot everything in the soil for this to be effective, depending on the specifics of your initial experiment).

27. Colored Celery

It’s hard to imagine plants having little capillaries inside them that transport water and nutrients, but this experiment shows that in action. It’s easy to set up, but you’ll have to wait at least a day to see some results. Your kids will be able to see how transpiration takes place and plants absorb water from the soil all the way up into their leaves.

• A few stalks of celery (celery works best for this because it’s a bit more visible, but you could also use flower stems)
• Different food coloring
• Place each stalk in a cup of colored water and make your predictions about what will happen.
• After a day or so you’ll see the celery leaves becoming the color of the water they’re standing in.
• Have your kids describe their observations (they can write down what they see or draw it if they prefer).
• If you look at the base of the stem you’ll also see tiny little holes that the colored water is traveling through.

When you’re done with the experiment, make sure you snap the celery and look inside – you should be able to see the capillaries in action. For more ideas, Little Bins for Little Hands has got some great hints and tips for this experiment.

28. Moldy Bread

This experiment is an oldie, but a goodie! Kids love looking at disgusting things and this one will certainly come up with the goods. Not only will kids learn about how mold grows, but they might also take on some lessons about the importance of washing their hands!

You might want to check out the results of this experiment at Science Alert before you start to see if your stomach is up to it.

• A few slices of bread
• Some ziplock bags
• Sticky little hands. 
• Get a few slices of bread and lay them out on your kitchen bench.
• Have your kids touch one piece of bread with dirty, unwashed hands.
• They can wash their hands with soap and water and touch another slice, then do the same using hand sanitizer.
• Leave one piece of bread untouched.
• Place them all in clear, labeled ziplock bags and predict which one will grow the most mold.
• Leave your bread slices for at least a week (it may take a bit longer, depending on the conditions where you live) and get the kids to record their observations.

You can also try wiping your bread slices on other surfaces to see what moldy results you get (their laptop or tablet is a great place to start)!

29. Sprouting Beans

Give your household a real survivalist feel by beginning an indoor garden. We recommend planting your beans in a clear cup so that your children can be privy to all of the processes during the plant’s journey.

• How does a plant grow?
• What does germination mean?
• What is in season to grow in our area now?
• Unprocessed Beans
• If you’d like your child to see every step of the process, consider placing the beans inside of a damp paper towel inside of a ziplock. 
• You can wait, see the germinated seed together, and then plant it inside of a small cup.
• Once inside the cup, watch it grow.

Extend your work by planting various beans and altering the growth conditions in order see what makes your beans grow best! 

30. Begin Composting

Begin your “go green” resolutions by teaching your child the value of composting! Best of all, once the science experiment is done, your family will have a recycling process that will last your entire lifetimes. 

• Why is composting important?
• How else can our household go green?
• Why do we need a foundation layer for compost?
• Compost Bin
• Organic Material
• First, create a compost bin. You can purchase one or build one out of wood. 
• To begin your composting, you’ll need even amounts of brown materials (think shredded paper, dryer lint, etc.) and green materials (think fruit and vegetable waste, lawn clippings, etc.). 
• If you’re really feeling fancy, throw some earthworms in there.

For days to come, your family will be able to discuss what can and cannot be broken down by the decomposers inside of the compost bin. Never-ending science! 

31. Turn Grapes Into Raisins

Your kids may or may not eat raising – but we can guarantee you, they’ve likely never considered the option of creating their own! 

• What other snacks can we make with science?
• Should we ever eat our experiments?
• How does this work?
• For this experiment, you’ll need grapes. (Really, that’s it!) 

Leave your grapes somewhere where they will not be disturbed and use this as an opportunity for your children to journal the changes in the grapes from day to day. Believe it or not, this type of sequential journaling is a valuable literacy skill! 

32. DIY Science Experiment

The best science experiment your child can engage in is the one they create themselves! Begin brainstorming a list of questions and let the world be their oyster as they plan and carry out their own experiments. Some of our favorite brainstorming questions, from Scholastic’s Science-Fair Project Guide, are listed below:

• What is the effect of toothpaste brand on teeth-cleaning power?
• What brand of trash bag can withstand the most weight before ripping?
• How does the type of material affect how long a shirt takes to dry?

65 Science Experiments for Kids: Have a Blast at Home

Is your kid bored at the weekends or while on school vacation? Are they couch potato-ing in front of the TV again? I know a brilliant way to keep your child entertained and engage their brain: science experiments.

Whether your child is intrigued by the thought of Imploding Cans or a Lemon Volcano, I’ve put together a list of 65 dazzling science experiments for kids! No need for a fancy science lab — you can do these all from the comfort of your home.

I’ll let you know exactly how to carry out each experiment. Gone are the days when there was nothing to do. Now you have 65 theories to test out!

Easy Science Experiments Kids Will Enjoy

Safety tips, faqs about science experiments for kids.

From making a cloud in a bottle to homemade bouncy balls, here are 65 easy science projects for kids to try. Plus, most use household items, making this a cheap way to pass the time.

1. Cloud in a Bottle

Tightly secure the lid on an empty plastic water bottle. Twist the bottom of the water bottle as tightly as possible. This will compress the air and push all the molecules inside together.

When you open the water bottle, the molecules expand, releasing the pressure and creating an instant cloud.

2. Floating Fish

Learn about solubility and density with this fun experiment. On the bottom of a glass plate, draw the outline of a fish with a dry-erase marker.

After a couple of minutes, slowly pour tap water into the corner of the dish until it covers the plate. The water will move towards the fish drawing, surrounding it. Tilt the plate from side to side and watch as the fish drawing starts to float!

3. Lava Lamp

Learn about density and make a lava lamp at home. Add two inches of baking soda to the bottom of a jar, then fill the rest with vegetable oil until full. These two ingredients won’t mix.

Combine ¼ cup of vinegar with a bit of food coloring in a separate cup. Mix together before pouring the solution into the jar with oil and baking soda.

Turn off the lights and shine a flashlight on your lava lamp!

4. Foamy Fountain (Elephant’s Toothpaste)

In this experiment, kids will make foam with a few household ingredients. In scientific terms, this is called an Exothermic Reaction.

Pour ¾ cup of hydrogen peroxide into a bottle. Add 10 drops of food coloring and one tablespoon of dish soap. Swirl it around to mix.

Combine three tablespoons of warm water and one tablespoon of dry yeast in a separate cup. Mix for 30 seconds.

Use a funnel to pour the yeast-water combination into the bottle and watch it fantastically foam!

Don’t touch the foam. We know it’s tempting, but it contains peroxide, which can irritate your skin and eyes.

5. Magic Milk

Pour whole milk into a shallow pie dish with a flat surface. Add a few drops of food coloring to different parts of the dish. You can use tons of different colors!

In a separate bowl, pour some dish soap. Dip a cotton swab into the dish soap and gently touch the surface of the milk with the swab.

The soap will lower the surface tension of the milk, and the colors will burst and swim around.

6. Egg in a Bottle

Did you know you can fit an egg in a bottle without breaking it? Firstly, boil and peel your egg. Then grab a glass bottle (no plastic!) and ensure that the opening is smaller than the diameter of the egg.

With an adult’s help, light three matches and drop them into the bottle. Place the egg at the bottle’s opening with the wide end pointing up. The egg will slowly squeeze into the bottle as the fire goes out!

7. Floating Ping Pong Ball

Levitate a ping pong ball with Bernoulli’s Principle! Make a paper funnel using thick card. With a grown-up’s help, cut a small hole in the bottom of the funnel.

Insert a straw into the bottom of the funnel and secure it in place with putty or tape.

Add a ping pong ball (or DIY foil ball) into the funnel and put the long end of the straw in your mouth. Blow into the straw and watch the ball levitate because of the high speed and low-pressure air.

8. Imploding Cans

Fill up a few empty soda cans with a bit of water. Then, fill up a large bowl with ice cubes and water.

Heat a flat frying pan on the stove and carefully stand your cans on the frying pan until they are hot. Using tongs, transfer the hot cans one at a time into the ice water.

When the cans drastically change temperature, they implode on themselves and crush inwards.

This is one for parents to do and kids to watch. It’s not safe for kids to do on their own.

9. Eggs and Toothpaste

Learn about the power of toothpaste in this shocking science project for kids. Fill up four glasses, two with soda and two with lemon juice. Then cover two eggs in toothpaste and pop one into a soda glass and another into the lemon juice glass.

Next, place two more eggs into the remaining glasses. This time, they’re not covered in toothpaste. Leave all the eggs in the glasses for 12 hours.

Once the time is up, remove the eggs, rinse under cool water, and pat dry. You’ll notice that the eggs covered in toothpaste feel and look different than those without. This emphasizes the significance and protective abilities of toothpaste.

10. Black Pepper Trick

Teach kids about surface tension and the power of soap in this fun and easy experiment. Pour a thin layer of water onto a plate. Pour a bit of ground pepper all over the water’s surface.

Then pour a tiny amount of dish soap onto your finger. Dip your finger into the water, and you’ll notice the pepper quickly zoom away from your finger.

Need something for your science fair project? People will love watching this one in action!

11. Ice Cream in a Bag

Have fun and try something yum! Pour four ounces of milk and cream, ¼ teaspoon of vanilla, two tablespoons of sugar, two teaspoons of vanilla, and food coloring (optional) into a zip-bag and ensure it’s securely closed.

Place the bag into a larger zip-bag and fill it with ice and a small handful of salt to surround the smaller bag. Zip it shut and hold either side while shaking back and forward for about five to eight minutes.

Yes, your arms will be tired. But in the end, you’ll have ice cream! Open the large bag and remove the smaller bag. Rinse off salt from the bag and open it up. It’s ice cream time!

12. Magic Melting Skittles

Grab a plate and line up Skittles around the edge of the bowl. Pour a little bit of boiling water into the plate to surround the bottom. Watch as the colors from the Skittles slowly melt off and swirl together on the plate.

This experiment has endless possibilities. Try it with different colors and shapes on the plate!

13. Bouncy Egg

Turn a raw egg into a bouncy egg! Simply place the raw egg (uncracked) into a glass. Cover it completely with distilled white vinegar and leave for 24 hours. After 24 hours, you can gently scrape off the eggshell, and you’re left with a squishy, bouncy egg.

14. Grow an Avocado Tree

Wash an avocado pit and insert four toothpicks halfway up the side, on all sides. Suspend the pit over a jar and fill the container with enough water to submerge the lower third of the seed. Make sure the broad side of the pit is facing down.

Keep the jar in a warm place out of direct sunlight and change the water every few days. After a few weeks, roots and sprouts should start appearing.

When the sprouts are about six inches, cut it back three inches. This will encourage more growth. When the stem has grown back again, plant the avocado pit in a 10-inch pot with soil, and voila! Your avocado tree will grow.

15. Make Slime

This exciting experiment will provide days of fun! Mix together ¼ of water and ¼ cup of white school glue in a bowl. Add a few drops of food coloring.

In a separate bowl, combine ½ tablespoon of Borax and another ½ cup of water. Stir to combine. Add the solution to the glue mixture, and enjoy playing with the slime!

16. DIY Rock Candy

On the stove, combine a 1:3 ratio of water and sugar. Bring it to the boil.

Let it cool for 10 minutes before transferring to a large glass or jar. If you want colorful rock candy, add food coloring to the solution and stir.

Pour half a cup of sugar onto a plate. Dampen a wooden skewer in water and roll it around in the sugar. Then place the skewer into the glass jar and secure it in place with a clothespin so it stays in the middle of the jar.

After five days, your rock candy will have formed. Use a skewer to break the piece of rock candy out of the water. Place it inside an empty jar to dry, and yum! You have your own rock candy.

Ask for an adult’s help for this one since you’ll be using high heat.

17. Baking Soda and Vinegar Balloon

Baking soda and vinegar can blow up a balloon without any help from your lungs. Using a funnel, pour about ¼ cup of vinegar into a bottle (with an opening small enough to stretch the mouth of a balloon over).

Put the mouth of the balloon over the funnel and add one tablespoon of baking soda to the balloon. Stretch the balloon over the bottle’s mouth and empty the baking soda into the bottle.

Watch as the balloon fills up with air. More technically, it’s carbon dioxide because that’s what happens when you combine baking soda and vinegar.

18. Frozen Bubbles

Blowing bubbles can be even more fun when the temperatures are below freezing. The bubble solution can freeze on the spot! You can do this with a bubble solution and a bubble wand — wave it around to produce bubbles.

The bubbles will either freeze mid-air, once they fall to the ground, or even while they are still attached to the wand.

Another option is to pour the bubble solution onto a plate or shallow bowl. Use a straw to blow a bubble into the solution. The bubble will slowly freeze, forming ice crystals.

You can pop the bubble and notice how it shatters and crumples rather than disappears like a normal bubble.

19. DIY Phone Speaker

When you don’t have your own Bluetooth speaker, you can easily make one with paper cups and toilet roll tubes. On the toilet roll tube, cut out an opening on one side that will fit the bottom of your phone.

On the paper cups, cut out a small opening to fit the end of the toilet roll tube through. Connect the pieces together, choose your favorite song, and insert your phone speaker into the toilet roll tube.

The system will naturally amplify the sound from the phone! Dancy party time.

20. Invisible Ink

Reveal hidden messages with this science project for kids. Pour ⅓ cup of baking soda and ⅓ cup of water into a bowl. Mix together before adding a cotton swab into the solution and writing a secret message onto a card.

Pour 100 percent grape juice into a cup. Dip in a paintbrush and paint over the secret message to reveal it. This is a great way to teach about acids and bases.

21. Milk Bottle Xylophone

Make music with items you already have in the house. Line up six glass bottles and pour a different amount of water into each jar.

Make music by tapping a metal spoon on each jar. Notice how the amount of liquid in each jar changes the sound waves and vibrations, resulting in a higher and lower pitch.

22. Dancing Raisins

Fill a clear glass with clear soda and fill another glass with water. Place a few raisins in each glass and notice how the raisins dance in the soda liquid but not in water. This is because the gas bubbles carry the raisins up, and when the bubbles pop, the raisins sink again.

23. Exploding Lunch Bag

This chemistry test is a great way to add excitement to a dull Saturday morning!

Fill a zippable lunch bag with ¼ cup of warm water. Add ½ cup of distilled white vinegar. Zip the bag shut.

Place a piece of tissue or paper towel down and pour three teaspoons of baking soda onto the middle. Fold the tissue over itself.

It’s time to be speedy! Open the zippable bag enough to add the baking soda tissue.

Once you’ve added it, quickly shut the bag, put it on the ground and step back. The bag will begin to expand and eventually… BOOM!

Do this experiment outside. You don’t want a mess on your living room floor!

24. Lemon Volcano

Let’s make citrus volcanos! This is a great one for science fair projects.

Cut the top and bottom off a lemon and carve out the insides. Add food coloring to the inside and fill the lemon with baking soda. Mix with a knife and watch as the baking soda starts to fizz out.

You can also try this with different citrus fruits, like an orange or grapefruit. Make it with different colors to have a rainbow volcano collection.

25. Walking Water Rainbow

Place seven identical jars or glasses in a row or a circle. Fill every second jar ¾ full with water, so jars #1, #3, #5, and #7 have water.

Then add a big squirt of red food coloring to jars #1 and #7, yellow to jar #3, and blue to jar #5. Jar #2, #4, and #6 will remain empty.

Fold six paper towels in half (hot-dog style), then in half again, making long, thin pieces of paper towels. Fold each paper towel in half (hamburger-style), so they make a tent shape.

Then place one end of the paper towel in the first cup and the other half in the second cup. Repeat with each paper towel.

Each cup should have two paper towel ends inside unless your cups are in a row. In that case, the first and last cups will only have one paper towel end inside.

After a couple of hours, the paper towels will have soaked up the food coloring using a capillary action. The colors mix together to create the shades of the rainbow: red, orange, yellow, green, blue, indigo, and purple.

26. Rising Water

Fill a shallow bowl with enough water to cover the bottom. You can add food coloring for more fun!

Place a tealight candle in the middle of the water and light it. Quickly place an empty glass over the candle.

The candle will gently burn out while water rises into the glass. This is a great way to teach Charles’s Law, which conveys how when temperature decreases, the volume does, too, allowing water to rise and fill the empty space.

Get an adult to help with the Rising Water experiment, since it involves fire.

27. Bend Water

Run your kitchen or bathroom tap with a very thin stream of water. Blow up a balloon and create static by rubbing it against a towel or your hair. Hold the balloon close to the water and watch as the water bends towards the balloon.

28. Citrus Pops Balloons

Limonene, a component in citrus, has the ability to dissolve rubber, which is a component of balloons (1) . Therefore, when you squirt citrus onto a balloon, it pops!

Blow up a few balloons. Peel an orange, ensuring you have large pieces of the peel to hold.

Hold the peel a few inches from the balloon, with the rind side facing the rubber. Quickly squeeze the peel so the liquid squirts onto the balloon, and it should pop!

Something To Note

Not all balloons will pop through this experiment. If the balloons are made from natural rubber, they will most likely pop easily. But if the rubber is vulcanized, it’s more durable and harder to dissolve.

29. DIY Compass

Never get lost again! To make a compass, stroke a strong magnet down one length of a sewing needle 50 times. Then flip the magnet and the needle, and repeat on the other side.

Cut a cork so it’s about 1.5 centimeters thick. Push the needle through the cork — you may need to use pliers, so ask a parent for help.

Next, fill a bowl with a few inches of water. Place the cork into the water, and it should point North.

30. Sink or Float

Take note of which ones sink and which ones float. Can you determine why?

31. Optical Illusions

Optical illusions are an incredible way to confuse your brain using your eyes. Why not get a book of optical illusions for your kids to flick through all summer? This will keep them entertained — and amazed.

32. Pumpkin Volcano

Cut a hole in the top of a pumpkin and clean out the insides. Pour ¼ cup of baking soda into the pumpkin with a squirt of dish soap and watch the pumpkin start to foam from the top!

33. Create a Marshmallow Catapult

Stack up six popsicle sticks and tie them together with a rubber band on either end. Then tie a wooden spoon and another popsicle stick together at the bottom end of the spoon. Push the large stack of popsicle sticks between the spoon and the second stick until it’s halfway down.

Secure it together by making an “X” with a rubber band where the two sticks meet. Then put a mini marshmallow on the spoon and pull it back slightly.

The marshmallow should fly through the air! If not, adjust your mechanism until it can catapult the marshmallows.

34. Make Ginormous Bubbles

Make the biggest bubbles your eyes have ever seen! Mix together six cups of distilled or purified water with ½ cup of cornstarch.

Add one tablespoon of baking powder, one tablespoon of glycerine, and ½ cup of dish soap. I recommend Blue Dawn dish soap .

Use it with a giant bubble wand. If you need to make your own giant bubble wand, do this beforehand so you can use the bubbles immediately.

35. Magnet Experiment

Fill a glass with water and add a few tablespoons of magnetic fine iron filings . Run magnets up and down the side of the glass and watch the iron fillings move around.

36. Paper Bridge

All you need for this are pieces of paper, two plastic cups, and a bunch of pennies. Create different types of bridges by trying out different designs with the paper. Add one penny at a time to the bridges to discover the strongest bridge design.

37. Shine Up Pennies

Discover how to clean copper pennies using household items. Fill different cups with different liquids, including white vinegar, soapy water, ketchup, and soda. You can fill up the other cups with any liquid you please!

Put a penny in each cup and wait 10 minutes. Then rinse the pennies with water and rub with a paper towel. Which liquid cleans the pennies best?

38. Egg Drop Challenge

The aim here is to drop the egg into the glass of water. So fill a glass full of water (make sure it’s big enough for the egg) and place a piece of cardboard or a small tray on top of the glass. Then place a toilet paper tube on top of the tray before balancing the egg horizontally on the tube.

When you’re ready, strike the tray or cardboard away with your hand, making sure to send it flying away without knocking over the water. The egg will hang in the air for a split second before dropping into the water.

39. Green Pennies

Above, I taught you how to polish pennies. Did you know you can turn pennies green using a very similar method?

Fill up two bowls with ¼ cup of vinegar and one teaspoon of salt. Mix well. Add a few pennies to each bowl.

After 10 minutes, remove the pennies from one bowl, rinse them, and lay them flat to dry on a paper towel.

Take the other pennies from the second bowl and place them onto the paper towel. Don’t rinse! Wait and see what happens.

The pennies that you rinsed will be polished. But the pennies you didn’t rinse will be green. This is called a patina — a layer caused by the weathering chemical process you just carried out.

40. Homemade Butter

Pour heavy cream into a jar and put the lid on tight. And start shaking! This is a great one for siblings so they can take turns because it can take up to half an hour for the cream to turn to butter!

As the cream solidifies, it separates from the buttermilk. When you remove the lid, pour the buttermilk away; underneath, you’ll have butter. Spread it on your toast, and enjoy!

41. Neon Flowers

Fill up a few glasses with water and five drops of food coloring. Mix well before adding white daisies or carnations to each glass. The next day, your flowers should be bright and colorful!

42. Expanding Soap

Watch what ivory soap does when you microwave it. Submerge a bar of ivory soap into water before cutting it into quarters and placing it on a plate. Pop it in the microwave for two minutes and watch as it expands into a pile of fluff!

43. Sticky Ice

Fill a container with water and ice cubes. Lay a piece of string across the container, ensuring the string is in contact with one or some ice cubes. Sprinkle salt over the string.

One minute later, gently submerge the ice cube slightly under the water to wash the salt off. Pick up the string, and you’ll notice that the ice cube comes with it!

This is because the salt melts the ice a little, and when you wash the salt away, the ice cube refreezes, attaching the string to it.

44. Density Jar

This is what I did my 5th grade science experiment on. Learn all about density with this cool and easy experiment.

Pour some honey into a jar, followed by corn syrup, dish soap, water, oil, and alcohol. The layers of liquid will sit on top of one another rather than mixing together!

45. Soap Boat

Cut out a mini boat about one-inch long using card or paper. Fill up a large tray or container with water. Dip a cotton swab into dish soap and place a tiny amount on the back of the paper boat.

Watch as it starts zooming around the water! This works because the soap breaks the surface tension of the water and creates a force strong enough to push the paper through the liquid.

46. Dancing Sprinkles

Place plastic wrap tightly over a bowl and secure it with a rubber band. Make sure there aren’t any wrinkles.

Pour a few sprinkles over the plastic wrap. Lean closely and hum songs near the bowl. The louder or higher you sing, the different sound waves you’ll create.

You can also try placing a speaker into the bowl before you place the plastic wrap over it. Once you’ve poured on your sprinkles, play a song and watch the sprinkles boogy!

47. Eggs and Salt Water

Fill a glass full of water. Fill a second glass all the way with water and add a bunch of salt. And finally, fill a third halfway with water.

Place an egg in the plain, full glass of water and watch as it sinks. In the salty glass of water, the egg floats. Finally, add salt to the third glass of water, allowing it to dissolve slightly before placing the egg inside.

What does the egg do? It floats. But if you pour water on top of it so the glass is full, the egg stays in the middle. This is a great science lesson to teach density to kids.

48. Leakproof Bag

Fill a plastic zippable bag half full with water and seal it shut. Stab a sharp pencil through the bag until it comes out the other side. Repeat with a few more pencils. Notice how the bag doesn’t leak water when you stab the pencils through!

50. Frozen Baking Soda

Fill a freezable tray with one cup of baking soda. Add three cups of water and food coloring. Mix well.

Add some figurine toys to the mixture and freeze the mixture overnight. Start pouring vinegar into the mixture as you try and rescue the figurine toys. The vinegar will slowly break down the baking soda with a fizzing reaction until you can break free the figurines.

51. Leaf Breathing

Fill three bowls with warm water. Place one freshly picked leaf in each bowl and hold the leaf down with a small rock. After a few hours, check back, and you’ll notice little oxygen bubbles all over the leaves.

These bubbles convey the oxygen coming out of the leaves. This highlights that plants breathe! They take in carbon dioxide and transform it into oxygen, which goes back into the air we breathe.

52. Exploding Colors

Fill a tray with baking soda. Fill an ice cube tray with distilled white vinegar. Add food coloring to the vinegar. Use an eyedropper to transfer the colored vinegar to the baking soda, and watch the colors explode!

53. Floating Paperclip

When you drop a paperclip into water, it will sink because it has a bigger density than water. But with this experiment, you can make it float!

Bend a paperclip to create an “L” shape. Balance another paperclip on the bottom end of the “L” shaped paperclip.

Gently lower the paperclips into the water, sliding out the “L” shaped one from beneath the second paperclip. The second paperclip will now float!

54. Viscosity Experiment

Fill three glasses with different liquids like water, olive oil, and honey. Place a ruler over the top of the glasses with a marble balancing above each glass.

At the same time, tip the marbles into the cups and watch which one reaches the bottom first. This is a great science lesson on viscosity.

55. Plastic Milk

Create your own plastic using milk. Pour one cup of fat-free milk into a saucepan with four teaspoons of white vinegar. Stir gently to combine.

Set the heat to a high temperature. Don’t stir. After a couple of minutes, the milk will start separating.

Gently stir the solution, and the milk will form a big curd called a casing. Voila! You’ve made plastic out of milk. You can mold and cut it into anything you want.

Adults should help set the heat to a high temperature and stir the milk. Don’t leave your child unattended with this experiment.

56. Oxidation With Apples

Learn about oxidation with this fun and fruity experiment.

Get 10 plastic cups and pour ½ cup of water in all but one cup. Then add ½ teaspoon of ingredients to each water-filled cup, including vinegar, honey, salt, sugar, baking soda, and anything else you’d like to try.

With the help of an adult, cut up 10 apple slices. Place one apple slice in each solution for 10 minutes.

Remove them from the solution and wait another 10 minutes. Notice how the oxidation process varies depending on what solution the apple slice was exposed to.

57. Sunscreen Science

Using bright construction paper, fold each sheet in half and open it back up. Squeeze sunscreen onto a paper plate and use a paintbrush to draw a picture on one half of the construction paper.

On the other half of the paper, apply a spray-on sunscreen. Leave the paper outside in the sun for a few hours, ideally all day.

Notice how the sunscreen bleaches the part of the paper that doesn’t have sunscreen on it. But the sunscreen portion is protected! This is a great way to enforce the importance of sunscreen.

58. Static Electricity Hair

Teach your kids about electrons and negative vs. positive charge with this silly balloon experiment! Rub the surface of a balloon with a cloth for around one minute. Hold it slightly above your head and watch your hair move upwards towards the balloon.

59. Chicken in a Cup

Punch a hole in the bottom of a plastic cup. Attach a paperclip to the end of the ribbon and weave the other side through the hole so the paperclip is inside the cup. Dampen the dangling part of the ribbon slightly.

Hold the cup tightly in one hand and use your other hand to squeeze the ribbon and pull it down in sharp, short movements. All going well, it should make chicken noises!

60. Gummy Bear Osmosis

Pour water, coke, salt water, and white vinegar into four separate cups. Add one gummy bear into each cup and wait 24 hours. Remove the gummy bears and notice how they expand or stay the same depending on the liquid they rested in.

Weigh and measure the gummy bears before and after the experiment to track exactly how much they changed.

61. Make a Sundial

Make your own sundial to help you tell time! Start by poking a stick in the ground. If you live in the Northern Hemisphere, tilt the stick at a bit of an angle to the North. If you live in the Southern Hemisphere, angle it slightly to the South.

Every hour, take note of where the stick’s shadow is pointing on the ground. So, at 7 a.m., head outside and mark the shadow with a rock. Repeat at 8 a.m., 9 a.m., and so forth. As long as the sun is in the sky, you can use your sundial to tell the time.

62. Homemade Bouncy Balls

Combine ½ teaspoon of Borax with two tablespoons of warm water. Add a few drops of food coloring (optional). Then add one tablespoon of school glue to a separate bowl. Add glitter if you’d like.

Now add ½ teaspoon of the Borax solution into your glue, followed by one tablespoon of cornstarch. Stir well.

Once the solution has hardened, pick it up and mold it into a ball. Leave it to dry for 10 minutes. Watch it bounce!

63. Instant Ice

Fill a plastic bottle with water and place it in the freezer for two hours. Carefully remove it from the freezer.

Place a bowl or cup upside down and set an ice cube on top of it. Then, slowly pour the cold water onto the ice cube and watch instant ice form!

As an extra step, you can pour the cold water into a glass. Then hold an ice cube slightly into the water’s surface and watch as the water slowly freezes beneath it.

64. Mystery Smell

Get an adult or friend to fill up various opaque containers with different objects, such as chocolate, milk, vanilla, and other fragranced items. The children should put a blindfold on and sniff the different containers, trying to guess what is inside.

65. What Dissolves in Water?

This experiment is fantastic for learning what dissolves in water and what doesn’t. Drop some ingredients into various cups — oil, sugar, pepper, flour, and more. Then add warm water and stir.

Make it more fun by guessing beforehand which ingredients will dissolve and which won’t. Were your theories correct?

It’s essential to stay safe during your science fair projects and experiments. Here are five tips for ensuring your child is safe while they meddle with science.

• Stay nearby: Don’t leave your child unattended while they perform science experiments. Stay nearby without distractions to keep an eye on what your child tries out.
• Wear protective clothing: It’s a good idea to wear a lab coat, glasses, and goggles while conducting experiments. Many ingredients, even natural ones, can irritate the skin and eyes.
• Provide clear instructions: Before your child attempts a science experiment, ensure you have given them clear instructions, and they have a good understanding of what to do.
• Only do approved experiments: The experiments on this list have been tried and tested many times. I urge you to stick with approved experiments. Don’t make up your own experiments, as many mixtures and chemical combinations can make toxic gasses.
• Work in a well-ventilated spot: Some ingredients might cause nausea, dizziness, and headaches. So always work in a well-ventilated spot near an air purifier or open window.

What Are the Most Popular Science Experiments?

The most well-known science project experiment is definitely the baking soda and vinegar volcano. It has a beloved place in school fairs, movies, and TV shows.

Other popular projects include invisible ink, growing crystals, making a vegetable battery, making a baking soda rocket, and elephant’s toothpaste.

What Are Some Simple Science Experiments?

Your science experiment doesn’t need to be super complicated.

Keep it nice and simple with these easy experiments:

• Magic Milk.
• Black Pepper Trick.
• Dancing Raisins.
• Sink or Float.
• Eggs and Salt Water.

5 easy science experiments to do at home

Check out these speedy STEM activities that kids can do on themselves!

Kids won’t need beakers and microscopes for these easy science experiments to do at home – they just need themselves!

Each of these five biology activities lets children discover how a human body system works. And by doing these ‘tests’ on their own bodies, they’ll get to see and feel exactly how their own systems function. (We promise it’s safe!)

“Going through the process of physically doing something gets people more excited than just reading about it or watching someone else do it,” says Evan Barnes, a biology instructor at Westmont College in California.

Challenge your kids to experiment on themselves with these activities – and watch them be wowed.

1. The Big Jump (muscular system)

What to do: Have your kids stand with their legs straight and try to jump. Then have them bend their knees and jump again. This time they’ll probably be more successful!

What’s going on: The muscular system is made of special cells called muscle fibres that contract to help your body move. “As you crouch, the muscle fibres in your thighs, hips and glutes contract,” MacKenzie says. “When you start to jump, the muscle fibres expand, and the effect is like a spring uncoiling.” That releases the energy needed for your body to jump. When your legs are straight, the muscles don’t contract, so they don’t release as much energy.

2. Spinning and Sitting (nervous system)

What to do: Have your child sit in a chair blindfolded, then stand up and spin in a circle seven times. Now, without removing the blindfold, have them try to find the seat to sit down. (Make sure you do this in a safe place that’s clear of obstacles!)

What’s going on : The nervous system relies on chemical and electrical signals to communicate with the brain and different parts of the body. Those signals are sent with the help of receptors that are all over your body – including hair-like structures in the inner ear. When those receptors are touched by the endolymph, a fluid inside the ear’s canals, they send a message to the brain that your body is moving. But after you stop spinning, the fluid keeps moving.

“That sends signals to the brain, brain stem and cerebellum, and the brain interprets this as movement,” says biology instructor Jamie Parker of Fordham University in New York City. “So, if the liquid is moving while you’re still, your brain still thinks you’re still spinning.”

3. Water Bottle Test (respiratory system)

What to do: Fill an empty water bottle with water and dump it into a large basin. (Tip: Do this in the sink!) Refill the bottle, mark the water level on the outside and place the cap back. Turn the bottle upside down into the basin. Then, keeping the mouth of the bottle underwater, take off the cap. Have your child insert a bendy straw into the jug, with the other end sticking out of the water.

Have your kid take a deep breath, then blow into the straw until no more air is in their lungs. When they’ve blown out all they can, place the cap back on the still-underwater jug. When you remove it from the water, you’ll see the water level has gone down, and the missing water replaced by air.

What’s going on: Our lungs breathe in oxygen that our cells need to live, then breathe out carbon dioxide as a waste product. The air in the bottle shows how much carbon dioxide they’ve exhaled – and how much lung capacity they have to inhale air.

4. Hopping Marshmallow (circulatory system)

What to do: Have a child stick a marshmallow on top of a toothpick. (A mini one is best, but any will do!) With their arm palm-up on a level surface, balance the marshmallow so that the toothpick sticks straight up over their wrist where they feel a pulse. You’ll see the marshmallow stick jiggle back and forth or even hop up and down. Then have your kid jog or do star jumps for 30 seconds, and repeat. The marshmallow stick will move faster!

What’s going on: The circulatory system is what causes the heart to pump blood and lymph through your body’s arteries and veins. Pumping blood into an artery creates a pulse. That’s what you feel when you press your fingertips to your wrist—and why the marshmallow stick moves when it’s balanced there. And after you exercise? “The heart pumps  more  strongly to send more blood to the areas of the body that are moving, bringing them more nutrients and oxygen,” Parker says.

5. Bag of Bones (skeletal system)

What to do: Grab a friend for this experiment! With a long string, Kid 1 measures the height of Kid 2, then cuts the string there. Then Kid 2 stretches their arms out to each side, and Kid 1 uses the same string to measure fingertip to fingertip. It will be almost exactly the same length!

Now fold the string in half, and measure from the bottom of the heel to the top of the femur (just under the rear end). It will be almost exactly half the distance from fingertip to fingertip. If you unfold the same string and then fold it in half twice, it will equal the distance from the elbow to the fingertip. Finally, unfold the string and refold it in thirds, and it will equal the circumference of the head!

What’s going on: The skeletal system is all about the body’s bones and how the muscles support them, helping us stand and walk. So, your skeleton’s limbs must be proportionate to each other. “If these proportions are uneven, it will impact your gait,” MacKenzie says. If your legs are uneven, you might limp. Or, if your arms are too long for your legs or your skull is too big for your spine, you might have trouble balancing.

Many people think science is difficult and needs special equipment, but that’s not true.

Science can be explored at home using everyday materials. Everyone, especially children, naturally ask questions about the world around them, and science offers a structured way to find answers.

Misconceptions about the difficulty of science often stem from a lack of exposure to its fun and engaging side. Science can be as simple as observing nature, mixing ingredients or exploring the properties of objects. It’s not just for experts in white coats, but for everyone.

Don’t take my word for it. Below are three experiments that can be done at home with children who are primary school age and older.

Extract DNA from bananas

DNA is all the genetic information inside cells. Every living thing has DNA, including bananas.

Did you know you can extract DNA from banana cells?

What you need: ¼ ripe banana, Ziploc bag, salt, water, washing-up liquid, rubbing alcohol (from a pharmacy), coffee filter paper, stirrer.

What you do:

Place a pinch of salt into about 20ml of water in a cup.

Add the salty water to the Ziploc bag with a quarter of a banana and mash the banana up with the salty water inside the bag, using your hands. Mashing the banana separates out the banana cells. The salty water helps clump the DNA together.

Once the banana is mashed up well, pour the banana and salty water into a coffee filter (you can lay the filter in the cup you used to make the salty water). Filtering removes the big clumps of banana cells.

Once a few ml have filtered out, add a drop of washing-up liquid and swirl gently. Washing-up liquid breaks down the fats in the cell membranes which makes the DNA separate from the other parts of the cell.

Slowly add some rubbing alcohol (about 10ml) to the filtered solution. DNA is insoluble in alcohol, therefore the DNA will clump together away from the alcohol and float, making it easy to see.

DNA will start to precipitate out looking slightly cloudy and stringy. What you’re seeing is thousands of DNA strands – the strands are too small to be seen even with a normal microscope. Scientists use powerful equipment to see individual strands.

Learn how plants ‘drink’ water

What you need: celery stalks (with their leaves), glass or clear cup, water, food dye, camera.

• Fill the glass ¾ full with water and add 10 drops of food dye.
• Place a celery stalk into the glass of coloured water. Take a photograph of the celery.
• For two to three days, photograph the celery at the same time every day. Make sure you take a photograph at the very start of the experiment.

What happens and why?

All plants, such as celery, have vertical tubes that act like a transport system. These narrow tubes draw up water using a phenomenon known as capillarity.

Imagine you have a thin straw and you dip it into a glass of water. Have you ever noticed how the water climbs up the straw a little bit, even though you didn’t suck on it? This is because of capillarity.

In plants, capillarity helps move water from the roots to the leaves. Plants have tiny tubes inside them, like thin straws, called capillaries. The water sticks to the sides of these tubes and climbs up. In your experiment, you will see the food dye in the water make its way to the leaves.

Build a balloon-powered racecar

What you need: tape, scissors, two skewers, cardboard, four bottle caps, one straw, one balloon.

• Cut the cardboard to about 10cm long and 5cm wide. This will form the base of your car.
• Make holes in the centre of four bottle caps. These are your wheels.
• To make the axles insert the wooden skewers through the holes in the cap. You will need to cut the skewers to fit the width of the cardboard base, but leave room for the wheels.
• Secure the wheels to the skewers with tape.
• Attach the axles to the underside of the car base with tape, ensuring the wheels can spin freely.
• Insert a straw into the opening of a balloon and secure it with tape, ensuring there are no air leaks.
• Attach the other end of the straw to the top of the car base, positioning it so the balloon can inflate and deflate towards the back of the car. Secure the straw with tape.
• Inflate the balloon through the straw, pinch the straw to hold the air, place the car on a flat surface, then release the straw.

The inflated balloon stores potential energy when blown up. When the air is released, Newton’s third law of motion kicks into gear: for every action, there is an equal and opposite reaction.

As the air rushes out of the balloon (action), it pushes the car in the opposite direction (reaction). The escaping air propels the car forward, making it move across the surface.
