During Earth Day week, the preschool students did many experiments to see the effects of pollution. One experiment showed them the effects of littering.
Talk about how much fun it is to go camping and have a picnic. Talk about fishing and swimming in lakes and oceans and rivers.
Create a mountain scene using a piece of aluminum foil. Mound up one end of the foil with blocks or wads of paper so one side of the mountain is higher and the other side of flat.
Tear up pieces of paper and throw on the foil like people are littering their campsites and picnic areas. Throw a plastic cup on the area, too.
Then pour some water on top of the mountain and let it roll down the foil.
Explain to the students that is what happens when people do not throw their litter in the trash can or recycle bins. The litter gets into the lakes and rivers and oceans making the water dirty and polluted for fish and swimmers.
