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. The authors both live in Vancouver, British Columbia. 80 pages (all in color), 8 1/2 x 10. NEW IN PAPERBACK
