Question 3. What is air? (Page 139)
Answer: Air is a mixture of various gases. It is not just one gas but a combination of many different gases like nitrogen, oxygen, and carbon dioxide that surround our Earth. This mixture is vital for life.
In simple words: Air is a mix of many gases.

🎯 Exam Tip: Remember to emphasize "mixture" as the key term when defining air, as it's not a single substance.

Question 4. How is oxygen gas replaced in the atmosphere? (Page 141)
Answer:
1. Animals and plants breathe in oxygen from the air and release carbon dioxide gas into the atmosphere.
2. During a process called photosynthesis, plants absorb carbon dioxide from the air and give out oxygen gas.
3. These processes happen at the same time, which helps to keep the amount of oxygen and carbon dioxide in the atmosphere stable. This means plants and animals rely on each other to keep the air balanced.
In simple words: Plants make oxygen during photosynthesis, while animals use oxygen and release carbon dioxide. This cycle keeps the oxygen level in the air balanced.

🎯 Exam Tip: Clearly mention photosynthesis by plants and respiration by animals as the two main processes involved in maintaining the balance of gases.

Activities

Activity - 1 (Page 139)

1. Take a container and fill it one-fourth with water.
2. Light the candle and fix it in the middle of the container and cover it with an inverted glass as shown in figure.
3. Immediately, mark the level of water in the glass.
4. After some time, observe the candle and the level of water in the glass.
Observation - The candle blows out and the level of water in the glass increases.
Deduction - This shows that water occupies space.

Question 1. Why did this happen?
Answer: Oxygen is needed for things to burn. The candle used up all the oxygen inside the glass to keep burning. Once the oxygen was finished, the candle went out. After that, the water moved up into the glass to fill the empty space where the oxygen used to be. This shows that air takes up space.
In simple words: The candle used all the oxygen and went out. Water then moved into the glass to fill the space left by the used-up oxygen.

🎯 Exam Tip: Explain the role of oxygen in combustion and how its consumption leads to a change in air pressure, causing water to rise.

Activity - 2 (Page 141)

Take an empty glass.

Question 1. It is really empty or does it have something inside it?
Answer: No, it is not really empty; air is inside it. Even though we cannot see air, it fills up any space that looks empty to us.
In simple words: The glass is not empty; it has air inside.

🎯 Exam Tip: Remember that "empty" in everyday language often means empty of solids or liquids, but space is still filled by air.

Question 2. Does water enter the glass?
Answer: No, water does not enter the glass when it is inverted and lowered into water. This is because the air inside the glass takes up space and stops the water from coming in. If you tilt the glass slightly, then it allows the trapped air to escape.
In simple words: No, water does not enter the glass because air inside blocks it.

🎯 Exam Tip: This experiment demonstrates that air occupies space, which is a fundamental property of air.

Question 3. Does the water now enter the glass?
Answer: Yes, bubbles are coming out of the glass. When the glass is tilted, the air trapped inside escapes as bubbles, allowing water to enter and fill the space.
In simple words: Yes, as air bubbles escape, water enters the glass.

🎯 Exam Tip: The formation of bubbles is a clear sign that the invisible air is being displaced by water.

Question 5. Can you guess what was in the glass?
Answer: Air was present inside the glass. The bubbles you saw coming out were the air leaving the glass, which then made space for the water to enter. This shows that air takes up physical space.
In simple words: Air was inside the glass, and it left as bubbles when water entered.

🎯 Exam Tip: Connecting the bubbles to the presence of air is the key observation in this activity.

Answer: Water is used for many daily activities. Here is a typical list of activities and the approximate amount of water used for each:

🎯 Exam Tip: When listing activities, try to cover different daily routines to show a comprehensive understanding of water use.

Question 2. Now, find out how much water your family uses in a day?
Answer: Based on the activities listed, a family uses approximately 35 buckets of water in one day. This total comes from adding up the water needed for each task. Water is an essential resource for all our household needs.
In simple words: Our family uses about 35 buckets of water each day.

🎯 Exam Tip: To get an accurate number, make sure to add up all the amounts carefully from the previous table.

Question 3. Now, divide this amount by the number of members in your family, to calculate amount of water used daily by one member.
Answer:
Members of the family = 5
Total amount of water used = 35 buckets
Water used per member = \( \frac { 35 }{ 5 } = 7 \) buckets
So, each person in the family uses about 7 buckets of water daily. Understanding individual consumption helps in conservation efforts.
In simple words: If there are 5 family members and 35 buckets are used, each member uses 7 buckets daily.

🎯 Exam Tip: Clearly show the division step and label all units correctly (buckets, members).

Question 4. How many people live in your village or city and how much amount of water will be needed for whole village or city in one year? Find out.
Answer:
Total members in our village = 450.
If each member uses 7 buckets of water per day, then:
Water required in one day for 450 members = \( 450 \times 7 = 3250 \) buckets
Amount of water in one year = \( 3250 \times 365 = 1186250 \) buckets
Therefore, a large amount of water, over a million buckets, is needed for the entire village in one year. This highlights the large scale of water needs.
In simple words: For 450 people, about 3250 buckets of water are needed daily, which is 1,186,250 buckets per year.

🎯 Exam Tip: Remember to multiply by 365 days to get the annual requirement and clearly show both daily and yearly calculations.

Question 5. What do you see?

Question 3. Explain water cycle with a suitable diagram?
Answer: The water cycle describes how water moves around the Earth. Water from bodies like rivers and oceans turns into vapor and rises into the air through a process called evaporation. This water vapor then cools down and forms clouds in the sky, which is called condensation. When the clouds become heavy, water falls back to the Earth as rain. This rain then returns to the water bodies, completing the cycle. This continuous movement ensures water is always available.
In simple words: The water cycle is when water evaporates from earth, forms clouds in the sky, and then falls back as rain.

🎯 Exam Tip: Use terms like evaporation, condensation, and precipitation (rain) to explain the stages of the water cycle clearly.

Question 5. Explain the importance of oxygen in atmosphere?
Answer: Oxygen is extremely important in the atmosphere because it is essential for all living things to breathe, a process called respiration. Both animals and plants need oxygen to get energy from their food. Additionally, oxygen is necessary for the process of combustion, which is burning. Without oxygen, fires cannot start or continue to burn, and many human activities would be impossible. Life as we know it would not exist without this gas.
In simple words: Oxygen in the air is vital for living beings to breathe and for things to burn.

🎯 Exam Tip: Highlight the two main roles of oxygen: respiration for life and combustion for energy/processes.

Long Answer Type Questions

Question 1. Explain diagrammatically, the component of air in the atmosphere.
Answer: Air in the atmosphere is made up of several gases and water vapor. These are the main components of air:
1. Water Vapour – When air touches a cold surface, the water vapor in it changes into tiny water droplets. This is how dew and fog form. The amount of water vapor in the air changes depending on the weather.
2. Oxygen - Oxygen makes up about 21 percent of the total air. It is very important for both animals and plants to breathe. It is also needed for burning things, like a candle or wood.
3. Nitrogen - Nitrogen is the most common gas in the air, making up about 78 percent of the total. It helps to dilute oxygen and does not support burning itself. Nitrogen is crucial for plant growth.
4. Carbon dioxide - Besides oxygen and nitrogen, air also has a small amount of carbon dioxide gas, as well as other gases like carbon monoxide and sulphur dioxide. These gases are present in small, fixed amounts. Carbon dioxide is essential for plants to make food.
In simple words: Air is a mixture mainly of nitrogen (78%), oxygen (21%), and small amounts of water vapor and other gases like carbon dioxide (0.03%). Nitrogen dilutes oxygen, oxygen is for breathing and burning, and carbon dioxide is for plants.

🎯 Exam Tip: When explaining components, state the percentage and a key function for each major gas to score well.

Question 2. What is soil should be taken to prevent it?
Answer: Soil erosion is when the top, fertile layer of soil is carried away by wind and water. To stop soil erosion and conserve soil, we need to take several steps. Planting many trees, a process called afforestation, helps to hold the soil in place. We must also protect natural forests as their roots keep the soil together. When harvesting crops, it is helpful to leave the roots in the soil to bind it. Building fences around fields with natural materials, known as bio fencing, also prevents soil from being blown or washed away. These methods help to keep the soil healthy and fertile.
In simple words: Soil erosion is the loss of topsoil by wind and water. To prevent it, plant more trees, protect forests, leave crop roots in the soil, and build natural fences around fields.

Long Answer Type Questions

Question 1. What is water harvesting? Why is it necessary? How can we harvest water?
Answer: Water harvesting is the process of collecting and storing rainwater. This water can then be used later instead of letting it run off and go to waste.
Water harvesting is necessary because only a small amount of the Earth's water is fresh and directly usable by humans and plants. Most of the water is salty seawater, which cannot be used directly. Due to less rainfall in some areas, more people, too much use in factories, and water wastage, the amount of clean drinking water is becoming less. So, we need to collect rainwater to meet our water needs. This helps maintain the natural water cycle and groundwater levels.
We can harvest water by collecting rainwater from rooftops. This water can be guided through pipes into tanks or pits dug in the ground. This stored water then slowly soaks into the soil, helping to refill the groundwater. Also, water collected in drains by the roadside can be directed to soak directly into the ground.
In simple words: Water harvesting means collecting and saving rainwater. It is important because we need to save fresh water due to less rain and high usage. We can do this by collecting roof water in tanks or letting it soak into the ground.

🎯 Exam Tip: When answering multi-part questions, ensure you address each part clearly. For water harvesting, explain what it is, why it's needed, and provide specific methods.

Question 2. How should we use water judiciously?
Answer: We should use water carefully to avoid wasting it. Here are some ways to do this:
1. Do not let water run from taps unnecessarily.
2. Fix any water leaks quickly.
3. Choose washing machines that use less water.
4. Keep drainage systems clean to prevent blockages and contamination.
