Dazzling Science Projects With Light And Color (Fantastic Physical Science Experiments)

Grade 4-6–The first title is devoted to light and seeing, mixing colors, and more. Each of 10 chapters includes an experiment, followed by an explanation of why it works, and offers ideas for devising projects to present at a science fair. For example, an experiment designed to show how light bends uses a pencil in a glass of water. Readers are then directed to find other ways to demonstrate the principle involved. The first chapter of Machines explains force, friction, distance, and work. The book then introduces levers, inclined planes, pulleys, etc. Both titles have the same introductory paragraphs about what science-fair judges look for and lists of safety rules that address the need for adult supervision. Large colorful, cartoonlike drawings complement the texts. Most of the materials required should be readily found at home or at school. These books may not be entirely accessible to children without some background in the principles discussed, but they offer solid information.–Maren Ostergard, Bellevue Regional Library, WA
