Explores such topics in physics as the properties of water, transmission of heat, evaporation, and air pressure as seen in home plumbing, refrigerators, and other common items

From School Library Journal

Grade 6-9?Friedhoffer explores basic physical principles of common devices and includes some science not found in his earlier volumes. Topics focus primarily on heat transfer, and air and water pressure. These phenomena are explained in terms of household items such as the refrigerator, toilet, and vacuum cleaner. (Noticeably absent are any electrical examples.) The explanations are clear and straightforward; in several places there are also simple demonstrations to build and perform using common objects. Black-and-white line drawings appear throughout. A list of resources, including Internet sites, is appended.?Alan Newman, American Chemical Society, Washington, DC
