Editorial Reviews

Children's Literature - Judy Katsh
A dozen projects demonstrating the principles of density, compression, and pressure are simply presented and clearly illustrated. Each project occupies a spread and presents a procedure, expected results, scientific explanation, and ideas for further exploration. A page of fascinating facts, a glossary, and an index make this project book a useful science study guide. The bold text and the friendly illustrations combine to make it visually appealing and scientifically inviting as well.
Children's Literature - Jeanne K. Pettenati J.D.
How does a hovercraft float on air? Why does ice float? Colorful pictures and simple, straightforward text guides children in step-by-step experiments to learn the answers to these and other questions. The projects included are easy to do at home and will engage children in science learning with hands-on activities. For example, children learn how some sea creatures are able to sink to the bottom of the ocean and float back to the surface. Deep-sea divers use this principle to study the ocean floor. Children make a diving jellyfish with a straw, paper clips and some clay. They are directed to fill a plastic soda bottle with water to make an "ocean." The jellyfish "dives" to the bottom of the bottle when a young scientist squeezes it. Squeezing the bottle pushes water into the straw, compressing the air. Because water weighs more than air, the jellyfish gets heavier and sinks to the bottom. Each experiment includes a final section explaining "Why it Works." This title, which is one in the publisher's "Fun Science Projects" series, includes a glossary and index at the back of the book. Learning basic science through play is the philosophy behind this series. Other titles include Hearing Sounds, Light and Color, and Understanding Electricity. Reviewer: Jeanne K. Pettenati, J.D.
School Library Journal
Gr 2-5–This colorful series will appeal to young scientists. The 12 experiments per title demonstrate a variety of basic science principles and include a short description of the principle, illustrated directions, a section explaining “Why It Works,” and ideas for further exploration. The older children in the grade range could try many experiments on their own. Experiments in which adult help is required are clearly marked. Unfortunately, there are no materials lists, and some of the directions, for example Sound’s “Add a little paper to the inner box,” are imprecise.
