A collaboration between NASA and the National Park Service, this educational video details how the sciences of astronomy and geography guided slaves to freedom in the 1800s, and how the technologies of satellites and geographic information systems are being used to locate and visualize the secret paths they traveled. Using the North Star as a compass, freedom-seeking slaves went from safe house to ... Full description.

This 2-3 week module, based on the National Aeronautics and Space Administration's Cassini mission to Saturn, uses the mission as a context for learning fundamental science/math concepts. It consists of six standards-based, constructivist lessons, enrichment activities, and supplemental material such as questions and answers, a glossary, and a chart of Cassini's position in the sky.

Gravity controls everything from the motion of the ocean tides to the expansion of the entire Universe. To learn more about the mysteries of gravity, twin NASA satellites named GRACE, short for the Gravity Recovery and Climate Experiment, are taking detailed measurements of Earth's gravity field. This experiment could lead to discoveries about gravity and Earth's natural systems, which could have ... Full description.

This film taken by astronauts from five Space Shuttle missions with the IMAX camera, dramatically illustrates forces affecting Earth's ecological balance: volcanoes, hurricanes, earthquakes, and, ultimately, humankind. Experiments discussed in the videotape focus on infrared detection of atmospheric remnants from volcanic eruptions, ozone concentration levels, and incoming solar ultraviolet radiation ...
