KIRKUS REVIEW

A "Let's-Read-and-Find-Out" book about the electricity that lights lamps and makes TV sets work. Simple experiments using a magnet, a coil of wire, and a magnetic compass demonstrate how electricity is generated; simple drawings show how it travels from a generator to homes. The topic is made more down-to-earth and accessible by limiting discussion to a consistent type of electricity--not, for example, bringing in batteries or lightning. Fine for the early grades.
