Children's LiteratureAuthor Sally Walker has written an easy-to-understand picture book on magnets. The five chapters include an introduction to magnets, magnetic materials, how magnets work, magnetic poles, and kinds of magnets. Good photographs illustrate the concepts outlined in the book. For example, the chapter on magnetic materials explains how some magnets are stronger than others. A photograph of a powerful junkyard magnet illustrates this fact. Another example is a photograph of a stainless steel sink with magnets stuck to its surface, showing that magnets can attach to magnetic materials. The author explains that most materials are nonmagnetic and that magnets do not attract nonmagnetic materials. A photograph shows magnetic items, such as paper clips, steel pins, and scissors, and an adjoining photo shows pencils, plastic pens, and rubbers erasers that are not magnetic materials. The chapter on magnetic poles explains the two parts of a magnet, called poles. One is called the North Pole and the other the South Pole. In the chapter titled "Kinds of Magnets," an illustration shows a paper clip's atoms lined up so their poles point in the same direction. Back matter includes further reading, Web sites, and a glossary. 2006, Lerner Publications, Ages 7 to 10.
