Soil's Secret

Tenth graders create maps to a secret location on the school grounds for others to follow, study topographical maps, estimate the size and shape of the Earth, explore various formations of the Earth's topography, and give an oral report...

In this soil formation worksheet, students will review examples of chemical weathering and biological weathering. Students will also review the different soil layers and how they are created. This worksheet has 6 matching, 5 multiple...

The general characteristics of fungus types are presented here. Your class will love the pictures of the amazing features found on these strange living things. The internal and external structures and their functions are highlighted. By...

Viewers explore vascular plants with a video that shows their different tissues, their ability to grow taller and wider, and their parts. Young scientists then see these plants xylem and phloem and learn how vascular plants move water...

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 activity on the activity of nematodes. Learners collect soil samples, bait them with insect larvae, and then examine insect carcasses over time to...

The question isn't whether trees can communicate with each other, but how their communication works. Learn about the intricate communication network between trees and the fungus in the soil, and how the relationship goes beyond a simple...

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...

Students 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...
