This activity uses food to demonstrate plate tectonic motions. Students construct a model using different snacks, which represent various parts of the Earth. For example, frosting represents the asthenosphere, fruit rollups are the Earth's plates, and graham crackers are meant to be the Earth's crust. Students learn how tectonic plates (lithosphere) ride atop the slow flowing asthenosphere layer, ... Full description.

NASA's Visible Earth is a searchable directory of images, visualizations, and animations of the Earth. The images are also listed under the following categories: agriculture, atmosphere, biosphere, cryosphere, human dimensions, hydrosphere, land surface, oceans, radiance or imagery, solid earth, locations, and satellites. Accompanying each image are credits, data about the image, the satellite it ... Full description.

This site is a collection of interactive, inquiry-based learning exercises for variety of science topics. Activities are grouped by category and include earthquakes and seismicity, global warming, absolute dating, hydrology, and biology. Earth science tutorials and online laboratory activities feature photographs, maps, diagrams, interactive graphs, and helpful illustrations and animations that make ... Full description.

This page offers two pieces of software that produce visualizations of seismicity, volcanic activity and wave propagation. The Seismic Waves program displays waves propagating out from the epicenter simultaneously on three-dimensional and cross-sectional views of the earth. These two views are synchronized with actual event waveforms so that as a particular phase arrives at a seismic station, one ... Full description.
