Activities

[Author - 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. Invite students to bring in a small amount of soil from their yards or from places around their communities. Make sure they label where they got the soil. Divide the students into small groups and have them compare and contrast the soil. Why might one soil be darker than the other? What might make one soil reddish in color? Where in the community might you find drier soil or sand? Have students discuss and write down their ideas.

3. Have students plant seeds in the soil near their home and observe how they grow. Which soil is best for plants? Which soil is worst? If possible, try experimenting with different seeds such as grasses, flowers, and vegetables. Different plants grow best in different kinds of soil.

Lesson Plan version 1.1 activities

1. Ask the class this question- what is under the floor of your classroom. Imagine that you have a digging machine to dig as deep as you want. You start digging. What would you find as you go down? Draw and show.
