Develop a model to illustrate how Earth's internal and surface processes operate at different spatial and temporal scales to form continental and ocean-floor features.

Dating Popcorn

How do geologists understand the Earth’s history? In part, they measure the age of rocks and other natural materials by dating techniques. They can date rocks by gauging the amount of decay of radioactive elements. You can simulate the dating process with popcorn.

EarthCaching

EarthCaching is an exciting educational activity through which you can learn about Earth and the natural processes that shape our planet over time. By combining GPS technology with outdoor field experiences, EarthCaching allows students and others to experience the wonders of Earth in an entirely new and entertaining way.

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.
