Electronic Field Trip
Hot Colors - Windows into Hidden Worlds
Premiered September 8, 2004

All viewers!!! We must stress that this field trip uses science fiction as a tool to teach middle school students about microorganisms, life forms that are unfamiliar to many people. In reality, Yellowstone's hot springs are extremely dangerous and easily damaged. In no way does this field trip wish to suggest that it is permissible to touch or enter these fragile natural resources.

A submarine capable of miniaturization has been pirated from the Yellowstone Ministry of Mysteries-and you are on the mission to retrieve it! As you trek through the park's "hot colors," you will experience the hidden worlds of microorganisms. These are worlds where human life cannot exist, where organisms draw energy from chemicals as well as from sunlight, and where extremes are the norm. Learn how these tiny life forms may represent the origin of life on the Earth and the possibility of life on other planets.
