Activity 1
1Recall different activities that you and your elders do during the day. How do these activities create waste? Finally, what do we do with the waste? Share your findings with your classmates.Show solution
Some examples of daily activities and the waste they create:
| Activity | Waste Created |
|---|---|
| Cooking food | Vegetable peels, eggshells, leftover food |
| Buying groceries | Plastic bags, wrappers, cardboard boxes |
| Eating packaged snacks | Plastic wrappers, foil packets |
| Reading newspapers | Old newspapers |
| Celebrating festivals | Decorations, plastic items, leftover food |
| Drinking water/juice | Plastic bottles, tetra packs |
What we do with the waste: We usually throw waste into dustbins. Some waste is collected by sanitation workers and taken away. Some people burn waste (which is harmful), and some people compost kitchen waste.
Conclusion: Almost every activity we do creates some waste. We should try to reduce, reuse, and recycle waste to keep our surroundings clean.

Activity 2 — Draw
1Draw or paste a picture of a locality. Identify the places where there is garbage or wastewater or smoke by circling them in red. Try to find out how the waste gets there. If you belong to a place that manages its waste well, ask the elders how it is done. Share your findings in the class.Show solution
Step 1: Draw or paste a picture of your locality (your street, neighbourhood, or village).
Step 2: Look carefully at the picture and identify:
- Places where garbage is dumped (near shops, roadsides, open plots)
- Places where wastewater flows (drains, puddles on roads)
- Places where smoke is seen (burning of waste, factories)
Step 3: Circle all these places in red colour.
Step 4: Think about how the waste gets there — people throw wrappers carelessly, drains overflow, waste is burned in open areas.
Step 5: If your locality is clean, ask elders how they manage waste — they may separate wet and dry waste, use compost pits, or have regular cleaning drives.
Share your findings with the class and discuss ways to improve waste management in your area.

Activity 3
1How can you help in reducing waste?Show solution
Here are ways I can help reduce waste:
1. Use a cloth bag instead of a plastic bag when going shopping.
2. Avoid buying food and drinks packed in plastic wrappers or bottles.
3. Carry water in a steel or copper bottle instead of buying plastic water bottles.
4. Take only as much food as I can eat so that food is not wasted.
5. Use both sides of a paper before throwing it away.
6. Avoid using disposable plates, cups, and spoons at parties — use washable ones instead.
7. Buy things that last longer instead of cheap items that break quickly and become waste.
Conclusion: By making small changes in our daily habits, each one of us can reduce the amount of waste we create.

Activity 4
1How can you REUSE things to reduce waste?Show solution
Here are ways to reuse things:
1. Paper: Reuse paper that has been used on one side for rough work, drawing, or making notes.
2. Water bottles: Instead of buying new plastic bottles, refill a steel or copper bottle with water.
3. Old newspapers: Use them to make paper bags, toys, or decorative items.
4. Old calendars: Use the blank side for drawing or writing.
5. Cardboard boxes: Use them to store things or make toys and models.
6. Old cloth: Use old clothes to make bags, dusters, or donate them.
7. Glass jars and bottles: Clean and reuse them to store spices, stationery, or small items.
Conclusion: When we reuse things, we give them a second life and reduce the amount of waste that goes into dustbins. This helps keep our surroundings cleaner.

Activity 5
1Create an item using waste material that you can give as a gift to someone. Show your Gratitude! You can give this to the person who helps to keep the locality or home clean.Show solution
Idea: Make a pen stand using an old cardboard tube or a used plastic bottle.
Materials needed: Old newspaper, used cardboard roll (from tissue paper), old magazines, glue, scissors, colours.
Steps:
1. Take an old cardboard roll or cut a plastic bottle to make a cylinder shape.
2. Tear old newspaper or magazine pages into small pieces.
3. Paste the colourful pieces all over the outside of the cylinder to decorate it.
4. Let it dry completely.
5. Your pen stand is ready!
How to present it: Wrap it in a piece of old cloth or newspaper. Write a thank-you note saying: 'Thank you for keeping our home/locality clean! I made this gift from waste material so that we can reduce waste together.'
Give it to the person who cleans your home, school, or neighbourhood and say a big 'Thank You' to them.
Conclusion: By making gifts from waste material, we show creativity, reduce waste, and express gratitude to those who work hard to keep our surroundings clean.

Activity 6 — Separate Your Waste
1Two dustbins are drawn below. Write the names of the waste material which will go into each of them. Items given: Plastic bottles, leaves, onion peels, light bulbs, rotten fruit, paper, eggshells, used plastic milk packets, cloth.Show solution
Concept:
- Green Dustbin (Wet/Biodegradable waste): Items that come from nature and can rot or decompose — like food waste, plant waste.
- Blue Dustbin (Dry/Non-biodegradable waste): Items that do not rot easily — like plastic, paper, glass, metal.
Sorting the given items:
Green Dustbin (Wet/Biodegradable waste):
1. Leaves
2. Onion peels
3. Rotten fruit
4. Eggshells
Blue Dustbin (Dry/Non-biodegradable waste):
1. Plastic bottles
2. Light bulbs
3. Paper
4. Used plastic milk packets
5. Cloth
Note: Sharp or harmful items like light bulbs should be wrapped in cloth or paper before putting them in the dustbin so that sanitation workers are not hurt while handling them.
Conclusion: Separating waste into wet and dry categories makes it easier to recycle and manage waste properly, keeping our surroundings clean and healthy.
