This document discusses the importance of reducing, reusing, and recycling materials to help the environment. It notes that thousands of trees are cut down each year to make paper and provides tasks and instructions for craft projects that reuse common household items like newspapers, plastic bottles, egg cartons, and tin cans to help teach these principles. Students are divided into groups and instructed to make masks from newspapers, cars from plastic bottles, jewelry from tin can pulls, and spies from egg cartons. The goal is to encourage recycling and reusing materials to solve environmental problems.
