This activity allows students to observe a small-scale model of liquefaction, a hazard associated with strong-magnitude earthquakes. The sand, water, and ping pong ball(s) represent the composites of soil: sediment, water, and air,...

Go on a geologic adventure in this interactive, online trail guide to the Wallace Creek site on the San Andreas Fault.

Explore the science behind the "extremes" in our world. Organized into sections on earth science, the animal kingdom, technology, and space science, this site opens your eyes to giant creatures, amazing technological advances, vast...

A resource to help understand that the movement of the Earth's tectonic plates is caused by convection. The plates' movements cause geologic features on the Earth's surface.

A lesson plan for investigating longitudinal waves by use of a Slinky toy. Directions, questions, and applications to seismic waves are provided.

In this video adapted from KUAC-TV and the Geophysical Institute at the University of Alaska, Fairbanks, learn how tectonic plate movement is responsible for building mountains, such as the Wrangell and St. Elias Mountains. 2m 16s

Use this site to teach your students what a tidal wave or tsunami is from this lesson plan. The discovery activity shows how a tsunami happens.

The Ring of Fire is a region of volcanic and earthquake activity that surrounds the Pacific Ocean. In this project you can explore the connection between plate tectonics and volcanic activity by mapping historical data.

What is the highest elevation on earth? How about the driest place on earth? Do you know where the greatest earthquake took place? Let Extreme Science take you to these places and other extreme places around the world.

This site is a very simple overview of plate tectonics. It includes a map of all the major plates and a diagram of the layers of the earth.

[Free Registration/Login Required] Students will investigate the scientific view of how the earth's surface is formed. Students recognize that lithospheric plates constantly move and cause major geological events on earth's surface....

Discover the ways in which the Earth's surface is always changing and what causes those changes through reference materials and a collection of activities.

Here's a common sense site about what to do in case you are in the area of a tsunami. This site is very interesting in that it provides lots of pictures of the damage a tsunami can do. Lessons were learned after these particular tsunamis.

Visit an active volcano site to find out the connection between the movement of the Earth's plates and the processes deep within the Earth's interior. [58:23]

Presents information and data on all aspects of the geography, natural resources, and climate of Texas, including natural disasters and extreme weather events.

Here's a project for studying compression waves in different soil types. It uses a homemade wave tank for solids, with a frequency generator, amplifier, and loudspeaker as the vibration source. There are lots of interesting possibilities...

This comprehensive overview of continental drift takes a historical look at the various types of evidence which led to the development of the theory.
