Gr 4-7 -These three oversize titles suggest fundamental experiments and projects using everyday materials. Each one begins with an introduction to the topic followed by two-page spreads of each scientific concept. The 12 experiments in each book have a materials list and step-by-step photo instructions. Boxed text explains the scientific ideas in each project and the processes that make it work, and offer ideas for further experimentation. The activities are followed by a history of the topic and a useful glossary. The first title introduces air movement, air pressure, wind resistance, lift, flight, and energy from the wind. The second book covers sound waves as they travel through air and underwater, high and low sounds, how we hear, the Doppler effect, soundproofing, and recorded sound. The third has experiments on the water cycle, water density, water as a solvent, surface tension, capillary action, buoyancy, water power, and water propulsion. The “Science Alive” series (Crabtree) covers each of the subjects in this series. However, the colorful illustrations, organization, and ease of use of Parker's titles make them excellent additions.-Ann Joslin, formerly at Erie County Public Library, PA
