Discuss with your children what is biodegradable and what is not. Then bury things in your playground. A few weeks later dig these up and show your children the difference between biodegradable substances and non-biodegradable items. Have your children save and bring in aluminum cans (make sure they are clean). You can collect these in a corner of your classroom. When you get a lot take them to your local recycling center and use the money to buy supplies to make a recycling book. If you have an area where you can start a compost pile. This will help your students to learne what items decompose in a compost pile, and what items do not. They can watch fruits, paper, grass, etc decompos and turned into fertilizer over time. Note: This will attract bugs so only do this if you can have if a good way away from the playground Talk to your children about the role plants and trees play in the environment. Then plant a tree with your childre. Note: talk to local owned businesses and you may be able to get a discount Three to Four weeks before Earth Day discuss with your class what is and what is not bio-degradable and what isn't. Bury different items in the playground. On Earth Day dig them up and see what items were Bio-Degradable. Provide your children with trash or ask them to bring some from home. Make a large lake on a piece of paper. Put fish in the pond. Tell your children how the fish used to live happily until people started coming to the lakes for picnics. When they were done eating they woud throw their trash into the pond. (have your children throw their trash into the pond and remove a fish for each piece of trash) Soon your children will see that the pond is full of trash and no fish. Next tell your children that some people decided to clean up the pond. Have them remove their trash one piece at a time. When all the trash is gone put the fish back in because they have room to swim. Wet a paper towel, and drop it along with six white beans into a Ziploc bag. Seal the baggie (leaving air in the bag) and put it in your window. Your children will love watching the beans grow.
