Activities

[Contributor - Kripa S]

1. Take a little soil. Break the clumps with your hand to powder it. Now take a glass tumbler, three quarters filled with water, and then add a handful of soil to it. Stir it well with a stick to dissolve the soil. Now let it stand undisturbed for some time. Observe the layers of soil and take notes.

2. Make a group of five students and discuss the uses of water in your daily life. Write down the uses. Classify the above uses of water in three

groups, uses in a house or family, for agricultural purposes and others.

3. Form groups of 4 to 5 students and discuss the following topics in each group. Prepare points and share. The topics to be discussed are :

a) What will happen if rainfall this year is less than last year?

b) What would happen if there was no rainfall for five years?

c) What could be the possible reasons for water scarcity in a particular place?

d) What problems can arise due to water scarcity in a particular place?
