Lesson Plan version 1.1 activties

1. Make a list of various materials used by us in daily life and classify them as natural or man-made material.

2. Ask students to identify the material from which following things are made:

Chalk (lime stone), wooden desk (wood), iron chair (iron), bricks (clay).

Now ask students (among the above discussed materials) which are inexhaustible and exhaustible material.

3. Ask students to make a list of type of fuels used in their neighborhood.

4. Ask students to find out where CNG is used in Jharkhand?

5. Take some containers. Fill them with popcorn/peanuts/roasted gram/toffees. Divide students into groups of seven each. Further divide each group into three subgroups containing 1, 2 and 4 students. Label them as first, second and third generation respectively. These sub-groups represent the consumers. As population is growing, second and third generations have larger number of consumers. Put one full container for each group on a table. Ask consumers of the first generation from each group to consume eatables from the container of their group. Now, ask the second generation consumers from each group to do the same. Ask students to observe carefully the availability of eatables in each container. If some thing is left in the containers, ask third generation from each group to consume it. Now, finally observe whether all the consumers of the third generation got the eatables or not. Also observe if anything is still left in any of the containers.
