Activity Overview: This activity focuses on the concept of a source reduction. Also known as waste prevention, source reduction decreases the amount of material entering the waste stream. Some examples of source reduction include buying longer lasting light bulbs to reduce the frequency of burnouts and therefore the number thrown away. Another example is refilling plastic water bottles. Even disposable bottles can be refilled from the tap, which reduces the number entering the waste stream, even for recycling.
Discuss how students can use less paper. Think of ways the whole school could cut down on paper use. Plan to share the results of this demonstration with the school.
Compare results across classrooms on your hall or in your department. Use tables, graphs, and other tools to analyze results. Are there correlations with between class sizes, subject matter, or any other parameters?
