Pbs Learning Media: Tectonic Plates, Earthquakes, and Volcanoes

This interactive activity adapted from NASA features world maps that identify different sections of the Earth's crust called tectonic plates. The locations of different types of plate boundaries are also identified, including convergent,...

Are three seemingly separate volcanoes in Iceland actually connected to each other? For the first time, scientists can study a volcano from the inside and find out that these volcanoes are actually connected. Find out how in this video...

Scientists study ice sheets because they influence weather and climate, playing a role in atmospheric and ocean circulation. Ice sheets can also have huge impacts on global sea levels because they store so much water. Explore this...

Three choices of virtual worlds to enter: a vulture, a wolf or a shark world. Once inside these worlds view videos, play games, and discover the ecosystems of these wild animals.

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

This video segment adapted from NOVA/FRONTLINE demonstrates the physical property of carbon dioxide that causes the greenhouse effect. Includes background reading and discussion questions. [2:26]

Students learn about the giant impact hypothesis for the Moon's formation, and how the Apollo Moon rocks have contributed to scientists' understanding of the Moon.

Everything in our environment is interconnected. A change in one area causes a change in another area. Nowhere is this more evident than in our climate. NASA created a theoretical planet called "Daisy World" to show the complex system of...

This video segment adapted from NASA's Goddard Space Flight Center explains how and where hurricanes develop. Learn how El Nino events alter the course of atmospheric circulation. Includes background reading material and discussion...

This interactive tutorial illustrates how spectrometry is used to study, identify, and quantify materials.
