GEMS: Invisible Universe Available Upon Request

In this GEMS guide intriguing activities deepen student understanding of the electromagnetic spectrum, enabling students to detect and consider wavelengths other than visible light. Activities feature energy stations, including infrared (TV remote); microwave (pager); ultraviolet (black light) and other devices. Students come up with their own tests to see what blocks each wavelength, and what does not. They learn how these other wavelengths can be used to "see" things we cannot see with our eyes allowing space scientists to detect and image objects, phenomena, and sources of energy far off in space. Colorful examples of these images are included in the guide.
