Dead trees provide nutrients for the soil, food for animals, protection and a home for organisms, a seed-bed for new trees, and a place for nitrogen-fixing bacteria to live. In the activity, pupils collect decaying logs, expose them to a...

Biology or ecology learners studying parasitism or food webs will learn a lot from this lesson on the activity of nematodes. Learners collect soil samples, bait them with insect larvae, and then examine insect carcasses over time to...

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...

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...

High schoolers simulate digging for forensics evidence at a crime site. They choose tools to use in order to reveal the clues and determine whether what they've found is relevant to the crime and how it relates. They write a report about...
