These quick and easy experiments provide a thorough introduction to what light is, how it behaves, and how it can be put to work. Robert W. Wood offers experiments that demonstrate the principles of light reflection, refraction, and diffraction so that students can thoroughly understand the changing qualities of light under various conditions. Young readers will also learn how to make and use such devices as a sundial, prism, Kaleidoscope, periscope, pinhole camera, stroboscope, and telescope. And a chapter is included on science fair projects that provides examples and explains the basic planning stages of a successful project.
