Chapter 4 of Class 5 EVS (Our Wondrous World), Our School — A Happy Place, follows Aasha and Mohit as they dream of turning their school into a “green school.”
Key Concepts
What makes a “green school”: managing waste properly, saving water, using electricity carefully, and planting trees.
Waste management: separating waste into dry waste (blue bin) and wet waste (green bin).
A happy school: comes from friendship, kindness, cleanliness, and a positive environment — not just good facilities.
Quick Recap
- Dry waste (paper, plastic, metal) goes in the blue bin; wet waste (food scraps, peels) goes in the green bin.
- Road, traffic, and fire safety around school are also part of keeping a school genuinely safe and happy.
Common Mistake to Avoid
Mixing dry and wet waste together — keeping them separate at the source makes recycling and composting far more effective.
Frequently Asked Questions
Why is separating waste into dry and wet important?
Wet waste can be composted into fertiliser, while dry waste can often be recycled — mixing them makes both processes harder or impossible.
What besides facilities makes a school a happy place?
Friendship, kindness among students and teachers, cleanliness, and a generally positive, caring environment.
