This website, from the 1998 PBS "Savage Earth" series, shows seismic waves from an earthquake that took place in Bolivia in 1994. The animation illustrates the way the earth's surface, core/mantle boundary and inner/outer core boundary reflect and deflect P- and S-waves. Full description.

This interactive, animated globe allows users to rotate it and change the virtual sea level by up to 200 meters, observing which areas are inundated. Full description.

This site is a joint effort of NOAA Research and the College of Education at the University of South Alabama. The goal of the site is to provide middle school science students and teachers with research and investigation experiences using on-line resources. In this unit students explore what El Nino is, where it is located, how it is created, and weather changes that El Nino causes. Students analyze ... Full description.

This video shows the retreat of the Laurentide ice sheet that covered much of North America from 18,000 to 8,000 years ago. Full description.

With this tool, users can build their own animations from infrared satellite imagery superimposed on a world map. Animations are constructed by selecting year, month, date, and time for the archived images. Users can also adjust the animation length, interval between images, and speed of the animation. Full description.

This animation shows the retreat of glacial ice, changes in the shoreline, and the disappearance of the land bridge across the Bering Sea which occurred at the end of the last ice age, beginning just over 21,000 years ago. Full description.

This animated model shows the predicted effects of glacial melting and changes in vegetation patterns in the Blackfoot-Jackson Glacier Basin of Glacier National Park, Montana. The scenario incorporated in the model consists of a predicted exponential rise in atmospheric CO2 concentrations, a 2xCO2 global warming scenario, with a concurrent warming of 2-3 degrees centigrade (4-5 degrees Fahrenheit) ... Full description.

In this exercise, students will study the three types of faults, investigate the association between faults and earthquakes, and examine the relationship between earthquakes and plate tectonics. There is a set of animations that illustrate the types of seismic waves, an exercise in which students determine the location of an earthquake epicenter using arrival times of P and S waves, and an exercise ...

The DataStreme Project is a pre-college teacher enhancement initiative of the American Meteorological Society (AMS). Its main goal is the training of Weather Education Resource Teachers who will promote the teaching of science, mathematics and technology using weather as a vehicle, across the K-12 curriculum in their home school districts. The initial step in the training of Resource Teachers is their ... Full description.

This educational module has been designed to provide students with the opportunity to interactively investigate the nature of earthquakes. The module has been divided into three major sections, "What is an Earthquake?", "The Distribution of Earthquakes", and "Measuring Earthquakes". Each section presents background material and interactive learning activities allowing students to understand such characteristics ... Full description.
