Question 4

Long Form

Discuss the process and importance of waste segregation into wet and dry categories.

Segregation involves separating waste into two distinct groups to manage it more effectively and cleanly.
Wet waste includes organic items like food peels and leftovers which can rot or be composted.
Dry waste consists of materials like plastic, metal, and paper that do not decay easily.
Using green bins for wet waste and blue bins for dry waste makes the process easy for everyone to follow.
In the classroom game, students practice this by putting chits of items like banana peels in the wet waste box.

How can schools encourage the reuse of items through recyclers and community involvement?

Schools can set aside items like old newspapers and metal instead of throwing them into regular dustbins.
Traditional recyclers can be invited to collect these specific items for processing and reuse.
Teachers can invite a recycler to visit the class and explain how their work helps the environment.
Students learn where their old items go and how they can be turned into something useful again.
For example, old newspapers are often given to recyclers because they should never be mixed with wet waste.

Question 6

Long Form

Explain the scientific reasons behind keeping a school building cool naturally.

Natural cooling can be achieved by utilizing trees to provide shade over the building walls and roof.
Windows should be kept open to allow breezes to flow through the classrooms and refresh the air.
White-colored roofs are used because they reflect the Sun's heat instead of letting it inside.
In contrast, black surfaces absorb heat, making the building much warmer during the day.
An example of natural cooling is using clay pots for water, which use a smart design to stay cool without power.

Question 7

Long Form

Describe the experiment involving black and white tiles to understand heat absorption.

To start the experiment, you take two identical tiles or stones and paint one black and the other white.
Both tiles are then placed outside under the direct heat of the Sun for a while.
After some time, you must touch each tile to feel the difference in their surface temperatures.
The white tile will feel much cooler because it reflects heat, while the black tile feels hot because it absorbs heat.
This activity helps students understand why painting a school roof white can keep the classrooms cooler.

Question 8

Long Form

Analyze the impact of dripping water and the importance of fixing leaks.

Water is a precious treasure, but it is often wasted through small leaks that go unnoticed.
A single dripping tap can fill a glass with water in a surprisingly short amount of time.
Over an entire day, these drops can add up to many liters of wasted water across the school.
Students can perform an activity by collecting drips in a glass and measuring the time it takes to fill.
For example, checking the water tanks to ensure they are clean and covered also helps prevent water loss.

Discuss how trees and greenery contribute to the school's ecosystem.

Trees act as natural air purifiers, helping to keep the air on the school campus clean and fresh.

Greenery serves as a habitat, providing food and homes to various birds and beneficial insects.
Students can even create specific areas like butterfly gardens by planting trees that attract them.
An example from the text is how the man in Assam created a forest that now houses elephants and birds.
