Essential Understanding

The student conducts classroom and outdoor investigations, following home and school safety procedures and environmentally appropriate and ethical practices.

Science Background

Recycling: Environmental Protection Agency (website) – Recycling creates valuable resources from materials that otherwise would become waste. This EPA website outlines the benefits to recycling, and explains the steps involved in the recycling process.

Reduce & Reuse: US Environmental Protection Agency (website) - By reducing consumption and reusing materials, individuals and industry can save natural resources and lower costs. Navigate this site for information about strategies we all can employ to conserve resources—and the benefits to be gained by doing so.

Signature Lesson

In Search of Recyclable Plastic: Wonderville (website) - Students collect and list plastic items from home, learn how to recycle different types of plastic, and become able to make informed choices regarding conservation and proper disposal of recyclable materials.

Supporting Lessons

Recycling: Discovery Education (website) - Students learn what biodegradable materials are, how they compare to man-made materials, and how they are “friendly” to the environment.

Elaboration Lessons and Extensions

Trash Art: US Environmental Protection Agency (PDF) - Scroll to page 59 for an activity that raises student awareness of the materials they throw away. With assistance from their parents, students collect trash from home, along with images of disposable garbage to create murals that illustrate how much we routinely waste.
