Students participate in a whole-class viewing and discussion about recycling.
Then in collaborative groups of two or three members they estimate how long it takes different objects to decompose on a time line. These peanuts will break down naturally when exposed to moisture. After discussion of the term biodegradable, the students make a time line from 1 to over 100 and place different items along the time line. We need to reduce, reuse, and recycle to save the earth from over-loading of our landfills. The students will have a better concept of how long certain items take to biodegrade.
