Conservation, Disposal and Recycling

Conservation, Disposal and Recycling

TEKS Objective

The student is expected to identify and demonstrate how to use, conserve, and dispose of natural resources and materials such as conserving water and reuse or recycling of paper, plastic, and metal.

Essential Understanding

The student conducts classroom and outdoor investigations following home and school safety procedures.

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.
