Children's Literature - Barbara L. Talcroft
Without energy there would be no life; transformation of energy from one form to another makes things happen. In this appealing "Energy in Action" series, tweens and even teens can learn how energy works in many different spheres. Each book includes big double-page spreads that define energy, matter, forces, and their interactions, using examples highlighting the book's topic. In this volume, the authors demonstrate how energy is used by the human body, starting with potential and kinetic, and including chemical, electrical, heat, light, and sound energy. Electrical energy sends messages through nerve cells (pictured in a diagram) to and from the brain. Light energy, produced in atoms by heat, allows us to see; especially interesting are vivid diagrams of the eye's structure, wavelengths of colors, and a prism breaking up light into its component parts. Another diagram pictures the human ear, where sound energy is transformed into kinetic energy, while a color photo shows girls listening to music on an mp3 player, where sound energy is transformed into electrical energy. As food (chemical energy) is changed into heat energy, temperature control is important; action photos show kids wearing warm layers in the snow and a sweating tennis player dispersing heat energy. Each book is sprinkled with sidebars conveying basic information and "Snapshots" about scientists like Hippocrates, who first understood how the skeleton and muscles work, and Luigi Galvani, who showed that nerves use electrical energy to make muscles move. A "Future Flash" page explains that scientists are experimenting with electrodes that can allow a disabled person to control appliances by using the brain's electrical energy. The books have an energy of their own with backgrounds of lively greens, blues, lavenders, and golds; well-selected illustrations are placed just where they're needed. An excellent value for the modest price! Reviewer: Barbara L. Talcroft
