Reviews

This series is well organized and written in clear, concise language. The first chapter in each volume focuses on why a particular form of energy is important for people and/or the environment. Successive chapters discuss how that energy is generated and how it can (or cannot) be manipulated to people's advantage. Simple experiments using everyday household objects with clear instructions are provided in almost every chapter, with appropriate notes when adult supervision is necessary. Crisp photographs and/or diagrams are presented on every page, as are side boxes that contain either additional information or ask questions that draw readers back into the main text. --School Library Journal, Series Made Simple
