Hot and Cold

Discovering Science is a first introduction to the exciting world of science. Vivid but simple text is complemented by large color photographs and clear, labeled illustrations. Each book contains 4-6 easy science projects, with simple, step-by-step guides and explanations. Throughout, these books there is an abundance of amazing facts and secret details of science that bring the subject alive for young readers. Simple explanations, illustrations, examples, and experiments that stress the child's need to "investigate" will be the introduction to the concept of matter.Here young readers move from what they already know about heat to the explanation of what causes heat energy. The most basic concepts, such as heat always moves to something that has less heat, are presented convincingly. Topics such as friction, chemical reactions, temperature, the thermometer, Fahrenheit and Celsius, are introduced. Conductors and insulators, and radiation are fully explained. Students learn how the Sun heats the Earth, how it affects our climate, and how plants and animals need this warmth.Hunter, Rebecca M. is the author of 'Hot and Cold', published 2000 under ISBN 9780739830161 and ISBN 0739830163.
