TIME REQUIRED:
20 minutes
MATERIALS:
Pictures, "Project Wild Handbook"
SET:
What would happen if your mother never swept the house, washed the dishes, picked up, or made up the beds? (response) (Explain that they would be dirty, hungry and probably get sick. Emphasize that our air, water and land must be kept clean in order for us to have them to use in the future.)
INSTRUCTION:
All of us like for things to be nice and tidy. It takes a little bit of work to keep things clean, but it is usually worthwhile. Air, land, and water are all part of our environment and they must be kept clean so they will last a long time. Throwing trash and garbage outside dirties up the land and makes it ugly. Oil spills and unhealthy things being put in our ponds, lakes, and streams makes them dirty. Smoke pollutes our air. We must all work together to keep air, water, and land clean.
(Have children discuss ways we keep things clean and list them on the board - garbage pickup, doing home chores, school chores, never littering.)
ACTIVE PARTICIPATION:
(Use the lesson Play Lightly on the Earth on p. 211 from the "Project Wild Handbook" with the children to help them distinguish between harmful and harmless, to the environment, activities.)
(Discuss with the children how smoking pollutes the environment and have them list ways to keep the environment clean.)
CLOSURE:
(Emphasize that it is up to each individual to keep his environment clean and to remind others to do this also. Discuss material on Litter We Know on page 51 in the "Project Wild Handbook.") Tell your neighbor one way to keep your environment clean. (pause, then summarize)
