Explores the properties of light and color by means of experiments and analysis of various optical instruments including periscopes, and telescopes. What could be more important than light? It makes plants grow; gives us food; lets us see bright, beautiful colors; and provides warmth. But to grasp the nature of light--and vision--we must understand optics. These delightful hands-on experiments vividly demonstrate the workings of absorption, reflection, refraction, and more. Toast marshmallows by the sun's intense heat. Create a "ray box," and view the entire spectrum through a water prism, and a rainbow in soap bubbles. Or try filters to really see the world through rose-colored glasses! Along with a materials list, the book includes safety instructions, explanations of the scientific principles underlying each experiment, a note on color blindness, and a glossary.
