Develop a model to describe the cycling of Earth's materials and the flow of energy that drives this process.

A Model of Three Faults

One of the most frightening and destructive phenomena of nature is a severe earthquake and its terrible aftereffects. An earthquake is a sudden movement of the Earth, caused by the abrupt release of strain that has accumulated over a long time. For hundreds of millions of years, the forces of plate tectonics have shaped the Earth as the huge plates that form the Earth's surface slowly move over, under and past each other. Sometimes the movement is gradual. At other times, the plates are locked together, unable to release the accumulating energy. When the accumulated energy grows strong enough, the plates break free. If the earthquake occurs in a populated area, it may cause many deaths and injuries and extensive property damage.

Burning Issues

Students will become familiar with fire terminology, realize how fire can be used as a management tool, and better understand the factors that need to be considered when planning a prescribed burn.

Chemistry of Burning

Why is CO2 increasing in the atmosphere? Who is doing it? Many people think that CO2 is “pollution,” so that clean burning should be a way to eliminate greenhouse gas emissions. In this demonstration, we review basic chemistry (see illustration) to realize that producing CO2 is an inevitable product of burning any fossil fuel.

Chocolate Rock Cycle

How sweet is this activity? It’s an introduction to the rock cycle using chocolate!

Glacier Slide

Glaciers can create lakes, valleys and areas known as kettle marshes. Their weight and movement are the tools a glacier uses to shape the landscape. Use this experiment to look at small "glaciers" and how they shape the landscape around them.

Global Change: Where Land, Air and Water Meet

The atmosphere is a mixture of gases. Similarly, the world's oceans and fresh waters contain dissolved chemicals. Many substances dispersed in air or water are measured in parts per million. Some of these substances are colorless, odorless, and tasteless, yet even in small quantities they can be toxic. To develop an understanding of parts per million as a concept, teams of students will create successive dilutions of a solution to reach a parts-per-million concentration.

How Can You Test Your Soil?

As a citizen scientist, you can use a soil test kit to find out how much of each type of chemical is in your soil.

Investigating Different Rock Types

In this investigation, you will explore the characteristics of various types of rocks.

Measuring Permeabilities of Soil, Sand, and Gravel

This investigation will help you to learn that different geologic materials have different characteristics.
