Selecting Soil Organisms in Compost
Students conduct an experiment to demonstrate that many of the enzyme systems needed to break down society's wastes exist in nature among the decomposers in a compost pile. They culture compost bacteria on starch agar to examine the...

Selecting Soil Organisms in Compost
Students demonstrate that many of the enzyme systems needed to break down--and therefore clean up-society's wastes already exist in nature among the decomposers. They select the best starch-munching organisms by altering the environment...

Energy, Matter, and Organization
Tenth graders review the Energy, Matter, and Organization unit. They have one week to complete an essay. Students must submit a concept map or drawing. The activity is introduces by reading a short story line which presents a simple...
Curated OER
Non-Nutrients: Fiber and Water
Students discuss how much fiber and water a person needs each day. They use beans soaked in water to show the benefits of water to the human body. They also learn the health benefits to eating healthy.
