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 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.

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, wind and water have eroded away most of the evidence; various other geologic processes have concealed it; oceans and vegetation now cover much of the rest. This activity will help your students understand how NASA scientists are discovering evidence ... 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.

Why are the Rocky Mountains so far inland? How do we preserve the changing Amazon rain forest? When will the Sun fling parts of itself towards Earth? The video magazine "Journeys through Earth and Space" follows three NASA research teams tackling these questions with supercomputers. "Journeys" begins with a short introduction that explains what supercomputers do and how scientists tap their power ... 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.

Windows to the Universe brings together scientific content on Earth and space sciences with interdisciplinary content on the arts and humanities. Three levels of content are provided: students (K-12 through undergraduate), teachers, and browsing adults. The site includes documents, images, movies, animations, sounds, games, and data. 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.

The activities in this 16-page magazine encourage children to look more closely at geology in their local environments and support their exploration of a range of dynamic Earth processes. Full description.
