Looking for something to do in the classroom that reinforces waste reduction issues in a fun and challenging way? These lesson ideas created by EcoSource will lead students through an interdisciplinary, curriculum-based learning experience. Carefully planned out lessons introduce students to the three Rs hierarchy. These lessons guide students from gaining an understanding of waste issues to personal action to reduce waste. We have divided the lessons up into reduce, reuse, recycle, and compost sections. In each of these categories there is a lesson for primary, junior and intermediate levels.
