Grades 6—8 Time: Four 30- to 50-minute sessions. In this GEMS unit, students will create magnifiers, simple cameras, telescopes, and slide projectors. They learn that lenses can be used for different purposes (i.e. camera lenses vs. microscope lenses.) The unit relates magnifiers to physics, optics, and light. |
