Building (Make It Work! Science)

Hands-on experiments introduce such structures as skyscrapers, dams, keystone bridges, igloos, and lock gates and show the materials used, the method of construction, and the source of strength.

Gr. 4-7. Part of the Make It Work science series, this focuses on 20 easy projects using everyday materials. After a brief introduction to general building essentials--plans, accurate measurement, safety, and tips on cutting, drilling, and joining--crisp color photos of children's models demonstrate the appealing, carefully explained step-by-step projects, which range from large structures (hooped tents, lattice domes, and igloos) to small play-type designs (various bridges, roof frames, and cable cars). In addition, a number of designs concentrate on water science, including dams, locks, and aqueducts. Words in bold appear in the glossary. The text is peppered with interesting facts and scientific background information, as well as challenging questions, to make youngsters think as well as do. There is a clean, neat appearance to the series, one that will encourage children to try their hand at "making it work." For other series titles, see the Series Roundup, this issue. Deborah Abbott
