In this ingenious unit, students use the same two lenses in different ways to create optical instruments, and in so doing find out how lenses are used in magnifiers, simple cameras, telescopes, and slide projectors. They learn that lenses have certain measurable properties that can help determine which lenses are best for specific purposes. This guide brings into practical "focus" important understandings related to physics, optics, and light, and makes a great connection to the GEMS guides Color Analyzers and Microscopic Explorations. Grades 6–8 4 Activities 68 pages ISBN: 0-912511-62-1 |
