Invisible Universe: The Electromagnetic Spectrum from Radio Waves to Gamma Rays (GEMS)

These intriguing activities presented in this comprehensive curriculum from Great Explorations in Math and Science (GEMS) deepen students' understanding of wavelengths other than visible light. Students come up with their own tests to see what blocks certain wavelengths and what does not. Students also learn how other wavelengths can be used to “see” things we can’t see with our eyes, allowing scientists to detect things in space. Fascinating discussions of gamma ray bursts and other electromagnetic phenomena. Activities and content are correlated to National Science Education Standards. Designed for grades 6 through 8.
