Editorial Reviews

Children's Literature
For all those kids who ask parents how the light switch works and what electricity is, this is a great book. It explains how electrical energy is produced and offers a simple experiment that kids should be able to conduct. Berger next describes how this energy flows to each house and the source of this electrical energy. Diagrams depict the circuitry outside and inside a home and illustrate the function of switches and electrical outlets. A close up diagram shows a light bulb and how it works. There is even an experiment on the closing page that will let kids produce an electrical current. An excellent choice for home and school and a level 2 book in the "Let's-Read-and-Find-Out Science" series. 2001 (orig. 1989), HarperTrophy, $15.89 and $4.95. Ages 5 to 9. Reviewer:Marilyn Courtot
School Library Journal
K-Gr 3-- An easy-to-understand, informative, and accurate science concept book. Berger uses clear, succinct language to explain how electricity is produced and transmitted, and how generators, light bulbs, and electrical plugs work. Directions are given for readers to produce an electric current using wire, a bar magnet, and a compass. Croll's clearly labeled drawings are excellent, showing the essential elements needed for understanding without unnecessary clutter. This is an excellent book for school and public libraries. Another good source of easy-to-read information about electricity is Challand's Experiments with Electricity (Childrens, 1986). --Eunice Weech, M. L. King Elementary School, Urbana, Ill.
