1. Ask around and find clothes or other household objects which contain:

a) Rayon

b) Nylon

c) Polyester

Also, find their properties, uses and differences between them.

2. Take two cloth pieces of the same size, roughly half a metre square each. One of these should be from natural fibre. The other could be a synthetic fibre. You can take help of your parents in selecting these pieces. Soak the pieces in different mugs each containing the same amount of water. Take the pieces out of the containers after five minutes and spread them in the sun for a few minutes. Compare the volume of the water remaining in each container.

3. Look around you. Name some articles made from plastic that you can see.

4.List some articles that are biodegradable and non biodegradable.

5. Debate: The children may be given an option to role play as manufacturers of synthetic fabrics or those of fabrics from natural sources.

They can then debate on the topic ‘My Fabric is Superior’.
