This site has information about where the tectonic plates were located in the Pleistocene and throughout geologic time. You can view animations of the plates moving or download models. Full description.

This booklet provides a brief introduction to the concept of plate tectonics and complements the visual and written information in This Dynamic Planet, a map published in 1994 by the U.S. Geological Survey (USGS) and the Smithsonian Institution. The booklet highlights some of the people and discoveries that advanced the development of the theory and traces its progress since its proposal. Although ... Full description.

This building-wide science enrichment program consists of a series of posters and accompanying questions designed to pique student interest in science concepts and their application to the world in which we live. Accompanying each poster are question sheets of increasing difficulty levels that students answer and submit at a designated location (collection box, office, etc.). Random prize drawings ...

This site presents a take-home web-based project for introductory geology students. The exercise has the students interpreting the sedimentary geology (lithology and fossils) of the Grand Canyon to create a geological history for the region. It is an open-ended exercise with no absolutely correct answer; it involves students acting as scientists - that is, the way real scientists think and combine ... Full description.

Researchers have identified approximately 140 individual impact craters on Earth. These craters probably represent only about 25 percent of those to be found. Assuming an equal rate of impact around the globe, many more craters remain to be discovered, particularly in remote land regions of our planet and in the oceans. This activity uses satellite images of several craters on the earth to study impact ... Full description.

This activity will help students understand how NASA scientists are discovering evidence of impact craters on Earth through satellite images and technology, which enables them to see landforms that we cannot see with our eyes alone. Earth and all the other planets and moons of our Solar System have been continuously pelted by asteroids and comets ever since their formation. On Earth though, wind and ... Full description.

Students will utilize the Internet to take a virtual field trip to visit a glacier and discover what physical effects glaciers have on the land. They will also have the opportunity to virtually visit Vermont and trace the pictorial history of how a whale's fossils were found there. The site also contains a student worksheet for their visual field trip. The site also provides an explanation of the ... Full description.

Discovering Plate Boundaries is based on 5 world maps containing earthquake, volcano, topography, satellite gravity, and seafloor age data. The novel aspect of the exercise is the "jigsaw" manner in which student groups access the maps and use them to discover, classify, and describe plate boundary types. The exercise is based only on observation and description, which makes it useful at a wide variety ... Full description.
