Class 3 The World Around Us • Our Wondrous World • Unit: Things Around Us • Chapter 12 • Reprint 2026–27
Answer-first chapter overview
Waste becomes easier to manage when we prevent excess, separate materials and follow the three Rs: Reduce, Reuse and Recycle.
Learning focus
Students investigate waste types, litter, wastewater, smoke, segregation, disposal, Reduce-Reuse-Recycle and sanitation work. This is one interdisciplinary Class 3 learning area integrating the natural and social world; it is not split into separate Science and Social Studies books.
Scope note: The current Class 3 text explicitly teaches the three Rs—Reduce, Reuse and Recycle. This page does not invent a five-R framework.
Observation activity
Audit one small bin with adult supervision. List waste types without touching them and suggest how each could be reduced or separated.
Think and answer
- What is waste segregation?
- Give one example each of Reduce, Reuse and Recycle.
- Why should sanitation workers be treated with dignity and provided safety?
How should this chapter be studied?
Start from a real observation, discuss what you notice, use the official chapter for context, complete the activity safely, and answer in your own words.
Is “EVS” the official current title?
