Chapter 1 of 8th Science , describes the use of Manure and Fertilisers on crops and the methods of replenishing the nutrients of soil through crop rotation. Use of irrigations and their methods, protection from weeds and use of weedicides given properly.

Chapter 2: Microorganisms: Friend and Foe

In Class 8 Science Chapter 2 we will learn about microbes. Do you know? Microbes can be classified into four major groups – bacteria, fungi, protozoa and some algae. Viruses are also known as Microscopic Organisms but they reproduce only inside the cells of the host organism. Common ailments like cold, flu and most coughs are caused by viruses. Serious diseases like polio and chickenpox are also caused by viruses. Corona [ COVID – 19 ] viruses also have made a disaster in all over the world. Harmful microbes cause or spread diseases whereas useful microbes also which are helpful for the environment as well as for the living of Human beings.

Chapter 3: Coal and Petroleum

In Class 8 Science Chapter 3 starts with the intro of Inexhaustible Natural Resources and Exhaustible Natural Resources. We have to study deeply about Coal, means formation, users and availability everything including Coal Gas, Coal Tar and Coke.

Mining and refining of Petroleum is also an interesting topic in Chapter 5 of Grade 8 Science . Natural Gas – CNG is also an important topic to study for exams. These all are natural resources and limited in quantity. So, we should use natural resources carefully and wisely.

Chapter 4: Combustion and Flame

In Class 8 Science Chapter 4 we will study about Combustion. Every combustion needs fuel. Do you know that the substance that undergoes combustion is said to be fuel (combustible)? Combustion of materials needs the oxygen and ignition temperature. The minimum temperature required to burn a substance is known as Ignition temperature .

The substances which have quite a low ignition temperature, they can easily catch fire with a flame. So, these are called inflammable substances. We should be careful about such substances and keep it away from the flame. Sometimes a material suddenly bursts into flames, without the application of any apparent cause, this is called spontaneous combustion.

Chapter 5: Conservation of Plants and Animals

In Class 8 Science Chapter 5, we will study about deforestation and its causes. Do you know that due to human activities the fertile land gets converted into deserts? It is called Desertification . We should more about Wildlife Sanctuaries, National Parks and Biosphere Reserve.

As we know that the plants and animals found in a particular area are termed flora and fauna for that area. So, we should preserve our flora and fauna. We should be more careful and protective about Endemic species, which are found exclusively in a particular area. We should know more about Endangered Animals whose numbers are diminishing to a level that they might face extinction.

Chapter 6: Reproduction in Animals

In Class 8 Science Chapter 6, we will study about the mode of reproductions like Sexual Reproduction and Asexual Reproduction . In sexual reproduction, male and female reproductive organs get involve. The male gamete is known as sperm and the female is known as ova. After the fertilisation , the zygote is formed with later on converted into an embryo. When, in embryo, all the body parts can be identified, now it is called a foetus. Budding and fission are common ways to generate the new young one in asexual reproduction.

Chapter 7: Reaching the Age of Adolescence

In Class 8 Science Chapter 7 we are going to discuss the period of life, when the body undergoes changes, leading to reproductive maturity, is called adolescence. normally the adolescence starts from the age of 11 and lasts up to 18 or 19 years of age. This period covers about thirteen to nineteen years of age, that is why adolescents are also called ‘teenagers’. The period of adolescence may vary from one person to another. At the age of puberty, there may observe the increase of height, change in voice, change in body shape and development of sex organs. In females, the reproductive phase of life begins at puberty and generally lasts till the age of approximately 45 to 50 years.

Chapter 8: Force and Pressure

In Class 8 Science Chapter 8 we are going to know about the terms related to forces and pressure. We know that any push or pull on an object can be treated as a force. The interaction between two objects results in a force between the two objects. If the forces applied on an object in the same direction, the net force can be obtained by adding one another whereas if the two forces act in the opposite directions on the object, the net force acting can be calculated by subtracting them. The strength of a force is known as the magnitude of the force. A force may bring a change in the state of motion, shape or position of an object.

Chapter 9: Friction

In Class 8 Science Chapter 9 we will learn about the force of friction and the factors which affect the friction. We know that friction is a necessary evil. It reduces the force but it is useful in most the actions. A moving object would never stop if there were no friction. The substances which reduce friction are called Lubricants . In some machines, it may not be advisable to use oil as a lubricant. We can reduce friction by putting an air cushion between the moving parts. Rolling of one body over the surface of another body, the resistance to its motion is called Rolling Friction . The frictional force on an object in a fluid depends on its speed in the fluid, the shape of the object and the nature of the fluid.

Chapter 10: Sound

In Class 8 Science Chapter 10 we have to study about sound and its characteristics. We will know here about vibration and devices which produce vibrations. We can produce a different type of sound with the help of the vocal cord. All the sound produced by a human is just because of the vibration of vocal cords. Sound always requires a material medium to propagate. Different sounds can be identified by their loudness, shrillness, pitch, etc., properties. Eardrums help us to hear all type of sound. The characteristic of sounds can be known by its frequency, amplitude, wavelength, speed and time periods.

Chapter 11: Chemical Effects of Electric Current

In Class 8 Science Chapter 11 we will try to know about different terms related to electricity. A substance may be termed as a good conductor or bad conductor depending on whether the current can flow through it or not. When we cover a metallic substance with another using electrolysis, it is called electroplating. It is useful to prevent the metallic substance from corrosion also.

Chapter 12: Some Natural Phenomena

In Class 8 Science Chapter 12 deals the activates known as Natural Phenomena . We all have seen the lightning and heard the thundering during the rainy season. The chapter starts with the concepts of charging and the types of charges as negative and positive. When two charged objects come close to each other, the transfer of charges takes place. Using electroscope, we can check whether an object is charged or not. It also describes the strength of charge. We must know the dos and don’ts during the thunderstorms or earthquake .

Chapter 13: Light

In Class 8 Science Chapter 13 we will study about light, visibility of objects due to light and laws of reflection. During the study about light, we should know about Incident Ray, Reflected Ray, Normal at the point of incident. The first law of reflection states that angle of incidence is always equal to the angle of reflection. According to second law of reflection, the incident ray, the normal at the point of incidence and the reflected ray all lie in the same plane. Terms lateral inversion, dispersion, diffusion and regular reflection are also important for exams. Multiple image of an object due to multiple reflection can be seen in Kaleidoscope . At the end of the chapter, structure of eye, defects of eyes and Braille system of writing is given as important part of chapter 13 of Grade 8 Science.

Science is interconnected with other subjects like mathematics, technology, and engineering. A solid scientific foundation enhances students’ abilities in these related fields.

Ans: sanctuary

(b) Species found only in a particular area are known as                 .

Ans: endemic

(c) Migratory birds fly to faraway places because of ______ changes.

Ans: climate

2. Differentiate between the following.

(b) Zoo and Wildlife Sanctuary

Ans: The difference between zoo and wildlife sanctuary is given below

(c) Endangered and Extinct Species

Ans: The difference between endangered and extinct species is given below

(d) Flora and Fauna

Ans: The difference between flora and fauna is given below

3. Discuss the effects of deforestation on the following.

(a) Wild animals

Ans: Effects of deforestation on wild animals: 

The destruction of trees or other vegetation from an area for industrial, agricultural, or other uses is known as deforestation. Many animals' habitats are made up of trees and other vegetation. As a result, if wild animal habitat is lost, their numbers will naturally drop.

(b) Environment

Ans: Effects of Deforestation on the Environment:

Photosynthesis occurs when plants absorb CO2 from the atmosphere. The level of CO2 in the atmosphere will rise if plants are killed. As a result, more heat radiation will be trapped by CO2, contributing to global warming. The natural water cycle will be disrupted if the Earth's temperature rises. As a result, there will be a shift in the pattern of rainfall. This could result in flooding or other disasters.

(c) Villages (Rural areas)

Ans: Effects of Deforestation on Villages:

The main source of revenue in the village is farming, which requires fertile soil. The trees are the ones who keep the soil fruitful by holding on to it. Without trees, the soil will become loose and readily swept away by the wind, and water will cause erosion, reducing the land's productivity. As a result, deforestation will have an impact on the villagers' livelihood.

(d) Cities (Urban areas)

Ans: Effects of Deforestation on Cities:

Because the amount of pollution in cities will be high, as will the level of CO2, trees will be required to clean up the pollutants and give fresh air. However, deforestation will result in a rise in pollution, particularly CO2 emissions from automobiles and industrial waste. It may also raise the temperature in the area, disrupting the water cycle.

Ans: Effects of deforestation on the Earth:

From a bird's eye view, if the number of forests decreases day by day, this will result in an increase in CO2 levels in the air, which will cause global warming by raising the temperature, causing polar ice to melt and sea levels to rise, potentially causing natural disasters. All of this is due to deforestation.

(f) The Next Generation

Ans: Imagine the impact that deforestation will have on the following generation, as we have witnessed the effects of deforestation on a worldwide scale. The likelihood of global warming, soil erosion, greenhouse effect, drought, and flood increases as the number of trees decreases day by day. As a result, these are the other issues that the next generation will confront.

4. What will happen if:

(a) We go on cutting trees.

Ans: If we continue to cut down trees indefinitely, the trees will eventually vanish from the face of the earth. Animals and birds will be displaced from their natural environment. Biodiversity will be extinct. The water cycle has been thrown off. The rainfall pattern has been thrown off. There are floods and droughts to be seen. Soil degradation, desertification, and natural disasters will all become more common.

(b) The habitat of an animal is disturbed.

Ans: When an animal's habitat is damaged, it loses access to basic necessities such as food, shelter, and protection. Creatures will murder other animals for sustenance, putting the survival of the fittest hypothesis into effect. Both vegetation and animals will dwindle in the end.

(c) The top layer of soil is exposed.

Ans: If the top layer of the soil is exposed, the nourishing lower layer of the soil, which is hard and rocky in character, will gradually open. Continuous soil erosion depletes the humus content of the soil, rendering it barren and unproductive.

5. Answer in brief:

(a) Why should we conserve biodiversity?

Ans: Plants and animals, as well as microorganisms, make up biodiversity. We all know that all living things are dependent on one another in some way. For example, food, nutrients, and shelter. As a result, if one of the pieces is impacted, the other two will be affected as well. To maintain biodiversity, all of its components must be cultivated and cared for.

(b) Protected forests are also not completely safe for wild animals. Why?

Ans: People who live near protected woods use the resources for their own needs, so the forests are not fully safe for wild animals. They murder animals for personal gain and sell the resulting products for a profit.

(c) Some tribals depend on the jungle. How?

Ans: Forests provide food, fodder, and fallen tree branches for tribals. As a result, people rely on wood for their everyday needs.

(d) What are the causes and consequences of deforestation?

Ans: Deforestation occurs for a variety of reasons. 

i. Forests are destroyed to accommodate developing urban centers and meet their ever-increasing needs.

ii. Forests are cut down to make way for crops and livestock grazing.

iii. Trees are felled for use as firewood.

Deforestation has the following consequences:

i. Soil erosion

ii. Biodiversity loss

iii. Floods and droughts

iv. Climate change as a result of global warming 

v. Water cycle disruption

(e) What is a Red Data Book?

Ans: The Red Data Book is a reference book that keeps track of all endangered animal and plant species around the world. The International Union for Conservation of Nature (IUCN) maintains this database (International Union for Conservation of Nature and Natural resources).

(f) What do you understand by the term migration?

Ans: The movement of an organism or a group of organisms from one place to another at a specific time each year is referred to as migration. Organisms move from one location to another to avoid harsh climatic circumstances or to reproduce.

6. In order to meet the ever-increasing demand in factories and for shelter, trees are being continually cut. Is it justified to cut trees for such projects? Discuss and prepare a brief report.

Ans:  No, chopping down trees to meet the needs of the human population is not justified. Trees provide a home for a wide range of animals and microbes. They give off O2 and absorb dangerous CO2 gas from the atmosphere, providing us with high-quality air. They protect against soil erosion as well as other natural calamities such as floods. They aid in the fertility of the soil and protect the planet from global warming, or the greenhouse effect, which is caused by people. The removal of forests will upset the natural balance. As a result, tree cutting for personal benefit should be prohibited, and forests should be preserved.

7. How can you contribute to the maintenance of the green wealth of your locality? Make a list of actions to be taken by you.

Ans: To begin, one should take care of the plants and trees that are already flourishing in the area in order to contribute to society's green wealth. Later, you can take action by planting more trees in the area. After that, one can begin to raise awareness among the general public and explain the significance to them. The tagline for the campaigns should be "each one plant one," and more trees should be planted and grown.

8. Explain how deforestation leads to reduced rainfall.

Ans: Deforestation refers to the removal of plants and other trees from the environment for industrial, agricultural, or human interests. Trees regulate the CO 2 and O 2 levels in the atmosphere and safeguard the planet from global warming. It also aids in the preservation of the earth's water cycle. Deforestation has the potential to disrupt the water cycle, raise global temperatures, and alter rainfall patterns. It can also cause draughts in certain areas.

9. Find out about national parks in your state. Identify and show their location on the outline map of India.

Ans: The Corbett National Park is one of the national parks near Delhi.

10. Why should the paper be saved? Prepare a list of ways by which you can save paper.

Ans: Paper is made from trees, as we all know. A tonne of paper requires seventeen fully grown trees. We also know that trees help to maintain the natural balance. As a result, we should conserve paper, which will save trees and, as a result, our ecosystem.

Paper can be saved by: 

decreasing the amount of paper used.

using both sides of the paper 

recycling paper

raising awareness about the dangers of misusing it

11. Complete the world puzzle.

• 5.0 CBSE Class 8 Science Preparation Tips

1. Understanding the Syllabus: Before diving into your studies, it is critical to gain full knowledge of the entire curriculum to avoid overlooking any topics. When you have understood what is required, the best plan is to divide the syllabus into smaller manageable parts. In this way, on the one hand, you can pay attention to the section at a time; on the other hand, you can organize better your study sessions, set realistic goals, and be sure that all topics are covered.

2. Regular revision: To keep information in your mind and make it solid, you need to revise it periodically. Another way is to test yourself on a topic without using the book or notes. Memory is enhanced through this active recall exercise, and areas that require more attention are identified. On top of that, flashcards can be used for reviewing the main ideas, definitions and terms in the course work. By constantly going through these flashcards, one might be able to easily remember what was contained in them keeping the information fresh in one’s mind hence making it easier to retrieve during exams.

3. Practice Regularly: If you want to excel in your examinations, regular practice is very essential. One of the strategies is executing mock tests, this can be an evaluation of personal preparation; hence, one can see where some improvements may be needed. When practising, focus on finishing the questions within the time frame to improve your speed and accuracy. 

4. Ask for Doubts: If you are having any doubts or questions while studying, never hesitate to ask for help. Ask your teacher or classmates who can help you understand the problem topics. Learning among one another's classmates helps because the discussion of the concepts confers understanding over and over again, with new insights.

5. Stay Healthy and Focused: Among the most important prerequisites for studying well are health and focus. Therefore, one should get adequate sleep at night to help the mind remain alert and the focus sharp.

Examples of situations in which you push or pull to change the state of motion of objects are

1. Pull situations

a) In order to open a drawer, we have to pull it. This action changes the state of motion of the drawer.

b) To draw water from the well, the rope is pulled. This action changes the state of motion of the bucket.

2. Push Situations

a) A football is pushed by the foot of a player. This action changes the state of motion of the ball.

b) In order to change the place of the heavy box from one room to another, we have to push it. This action changes the motion of the box.

2. Give two examples of situations in which applied force causes a change in the shape of an object.

The forces which change the shape of an object are as follows:

i) By pressing the clay between the hands, it deforms.

ii) The shape of the plastic bottle changes by squeezing it.

3. Fill in the blanks in the following statements.

(a) To draw water from a well, we have to __________ at the rope.

(b) A charged body __________ an uncharged body towards it.

(c) To move a loaded trolley, we have to __________ it.

(d) The north pole of a magnet __________the north pole of another magnet.

• To draw water from a well, we have to pull at the rope.
• A charged body attracts an uncharged body towards it.
• To move a loaded trolley, we have to pull or push it.
• The north pole of a magnet repels the north pole of another magnet.

4. An archer stretches her bow while taking aim at the target. She then releases the arrow, which begins to move towards the target. Based on this information, fill up the gaps in the following statements using the following terms.

muscular, contact, non-contact, gravity, friction, shape, attraction

(a) To stretch the bow, the archer applies a force that causes a change in its __________.

(b) The force applied by the archer to stretch the bow is an example of __________ force.

(c) The type of force responsible for a change in the state of motion of the arrow is an example of a __________ force.

(d) While the arrow moves towards its target, the forces acting on it are due to __________ and that due to __________ of air

(a) To stretch the bow, the archer applies a force that causes a change in its shape .

(b) The force applied by the archer to stretch the bow is an example of muscular force.

(c) The type of force responsible for a change in the state of motion of the arrow is an example of a contact force.

(d) While the arrow moves towards its target, the forces acting on it are due to gravity and that due to friction of air.

5. In the following situations, identify the agent exerting the force and the object on which it acts. State the effect of the force in each case.

(a) Squeezing a piece of lemon between the fingers to extract its juice.

(b) Taking out paste from a toothpaste tube.

(c) A load suspended from a spring while its other end is on a hook fixed to a wall.

(d) An athlete making a high jump to clear the bar at a certain height

a) We make a muscular force to extract the juice of the lemon by squeezing it. As a result, the shape of the lemon gets changed.

b) To take out paste from the toothpaste tube, we use our muscular force. This muscular force acting on the toothpaste tube leads to a change in its shape.

c) Here, the suspended load exerts a force on the spring and pushes the spring downwards. As a result, the spring gets stretched. Hence, its shape gets changed.

d) The feet of the athlete exert muscular force on the ground, which pushes the ground. This allows them to jump over the bar. As a result, their state of motion gets changed.

6. A blacksmith hammers a hot piece of iron while making a tool. How does the force due to hammering affect the piece of iron?

A blacksmith uses their muscular force while hammering a hot piece of iron. The muscular force changes the shape of the iron so that it can be given the desired shape.

7. An inflated balloon was pressed against a wall after it had been rubbed with a piece of synthetic cloth. It was found that the balloon stuck to the wall. What force might be responsible for the attraction between the balloon and the wall?

When an inflated balloon is rubbed with a piece of synthetic cloth, it becomes charged. A charged body attracts an uncharged body. When this charged balloon is pressed against a wall, it sticks to the wall. Thus, the electrostatic force acts between the charged balloon and the wall.

8. Name the forces acting on a plastic bucket containing water held above ground level in your hand. Discuss why the forces acting on the bucket do not bring a change in its state of motion.

For holding the bucket of water above the ground, we use muscular force. This muscular force acts against the force of gravity that pulls the bucket towards the ground. The two forces are equal in magnitude but opposite in direction. Therefore, the net force on the bucket is zero. Hence, there is no change in the state of motion.

9. A rocket has been fired upwards to launch a satellite in its orbit. Name the two forces acting on the rocket immediately after leaving the launching pad.

The force of gravity is the one which acts on the rocket to pull it towards the ground, and the other one is the force of friction due to the earth’s atmosphere, which opposes its motion.

10. When we press the bulb of a dropper with its nozzle kept in water, the air in the dropper is seen to escape in the form of bubbles. Once we release the pressure on the bulb, water gets filled in the dropper. The rise of water in the dropper is due to

(a) pressure of water

(b) gravity of the earth

(c) shape of rubber bulb

(d) atmospheric pressure

a)   Due to the atmospheric pressure, there is a rise of water in the dropper.

When all the air escapes from the nozzle, the atmospheric pressure, which is acting on the water, forces the water to fill up the nozzle of the dropper.
