Glass under water can be cut and sliced in much different ways than above the surface, so you can easily create your own glass designs to show your students in a safe way.

45. Can Eggs Float?

Finally, on our list, we have the experiment that has shown students for years how eggs can float on water if salt is added to the liquid. It’s a simple way to explain density, and it’s always a good idea to bring in the Dead Sea example.

The Dead Sea is so salty that people can simply float on its surface, but it’s also deadly because if you turn around – it’s difficult to get your head out of the salty water! 

Things To Remember

There are always things you should remember when it comes to these sorts of experiments. Some are much more obvious than others, but it’s always important to ensure we’re on the same wavelength. These include the following.

Safety 

Conduct a health and safety risk assessment before you carry out any experiment, and always be aware of any safety equipment you and your students may need to wear. Be sure to take reasonable care with all of your experiments (and best to do a trial run first!).

Reinforce Learning 

It’s all fine and good demonstrating the experiments, but you must ensure that you reinforce the student’s learning by asking questions at the end of the lesson. It’s also wise to set some theoretical homework based on their practical experiment. 

Do Your Research 

It’s of course critical that you know exactly what you are doing before you show your students, but it’s also as important to know your students. For example, if an experiment is more tailored for younger students, do not try it for older kids.  You may also like: 1st grade science project ideas .
