Gr 6 Up-Most science project books aim at demonstrating some basic principle(s); this volume goes one step further to emphasize the applications. Goodwin explores extensions of basic laws of physics to simple devices (like a bicycle), environmental technologies, meteorology, and robotics. Some of the projects are quite clever such as designing a practical rocking chair. All utilize household or easily purchased materials. Several call for power tools and, therefore, adult supervision. Clear descriptions of construction are followed by suggestions for more sophisticated applications, some of which require expertise far beyond that of the initial project. Black-and-white drawings and photographs outline the experimental set-up and illustrate some real applications; also included is a short chapter on science fairs. Demonstration books with an engineering focus are not common and this second collection of ideas from this author is a welcome addition.-Alan Newman, American Chemical Society, Washington, DC
