Fun With Science: Earth Science

From site:  If you're looking for ideas for a science fair project or demonstration, these pages may help you find a topic that would be fun to explore. They also provide ideas for teachers who are looking for classroom demonstrations or hands-on, inquiry-based student exercises to expand their curriculum.

I am an Emeritus US Geological Survey Geophysicist specializing in seismology and earthquake location programming...

Projects and lesson plans described in the Earth Science section include a tabletop earthquake demonstration, an earthshaking lab, a shake table, and a paper model that illustrates sea floor spreading, subduction, faulting, and the source of volcanic arcs.

In addition to Earth Science projects, the Earthquakes section has links to some USGS sites that will help in keeping track of current earthquake activity. If you want to make your own seismic recorder (called a seismometer), check out the Public Seismic Net section where you can read about my design and find links to other Public Seismic Network (PSN) web sites.
