ENERGY MAKES THINGS HAPPEN

Explaining sophisticated scientific concepts in terms that are both interesting and understandable is a rare talent. Bradley (Halfway to the Sky, p. 100, etc.) successfully leaps over that bar in this lively exploration of the broad concept of energy, another offering in the venerable Let’s-Read-and-Find-Out Science series. She begins with simple examples of different types of energy, introduces the concepts of storage and transference of energy, and then covers various aspects of energy: wind, types of fuels, food, solar power, and the formation of fossil fuels. Two final pages, set in a smaller type size, offer suggestions for simple experiments using toy cars and a reasoning game thinking of the origins of energy sources. The appealing cover illustration by Meisel (Trick or Treat?, p. 1395, etc.) shows a multi-ethnic group of energetic children hopping along in a sack race, and the lively internal illustrations, done in watercolor and ink, show all sorts of energy in motion: a tug-of-war, kites, hot-air balloons, windmills, and kids playing a variety of sports. Attractive endpapers show a lake scene with children and adults enjoying different kinds of boats, all under the warm glow of the sun. Energetically recommended for most library collections.
