Electronics Projects for Young Scientists

School Library Journal

Gr 9-12-- In addition to presenting various projects, this book discusses Ohm's Law using simple mathematics, and defines a host of components (from resistors to integrated chips) and their schematic symbols. The activities range from the time-honored crystal radio to sophisticated (and interesting) circuits for electronic dice and an intercom. The projects are clearly outlined with all the necessary materials listed. Where appropriate, adequate safety warnings are included. However, because the projects escalate quickly in complexity (e.g., from crystal radios to power supplies connected to potentially dangerous household current), adult supervision or previous experience is strongly advised. The black-and-white illustrations range from circuit diagrams to scattered--and sometimes blurry--photographs. --Alan Newman, American Chemical Society, Washington, DC
