Each book provides a collection of activities to help explain such physical science topics as light paths, chemical reactions, and senses. Varying in creativity, the experiments range from simple observations and model building to collecting data across multiple trials. Volumes include safety precautions and color illustrations and diagrams that help clarify experimental setups and science content. Reading list, websites. Glos., ind.

Is the moon really bigger when it rises? Where is the image you see in a mirror? Despite the title, there is nothing "easy" in this lively book in Gardner's Easy Genius Science Projects series, but the physics involved are nonetheless fascinating and will grab curious readers. With instructions for doing experiments on light sources and paths, colors, lenses, mirages, and much more, the inviting and chatty text for each project includes a boxed list of "things you will need," all of them commonly available, followed by detailed step-by-step instructions with clear diagrams. In many cases Gardner warns of danger and the need for adult supervision. Excellent boxed suggestions for related experiments make this book a great resource for lab use, and it is sure to stimulate plans for more science-fair ideas and projects. Back matter includes a glossary and bibliography of books and Web sites.
