Grade 4-9?An extremely useful offering. The book contains, in addition to explanations of many facets of magnetism and electromagnetism, 26 experiments illustrating these principles. Each includes a list of materials required and directions. Some activities are very simple, such as using iron filings to show the lines of force of a magnetic field around a store-bought magnet. Others are more complex, such as building a dynamo or spool and thread motor. Science "magic tricks" and games are yet another group of projects illustrating the principles of magnetism. All activities are well diagrammed, and ample safety instructions are given. Pen-and-ink drawings add much to the clarity of the instructions.?Margaret M. Hagel, Norfolk Public Library System, VA

Gr. 5^-9. From the discovery of the lodestone (an ancient Greek legend) to the use of magnetic technology in the space program, this clearly written book introduces the science of magnets. Throughout, explanations of scientific principles are expanded by activities that demonstrate the concepts. These activities vary from simple (magnetizing a screwdriver) to practical (building a motor) to playful (making a magnetic hockey game) to out-of-this-world (collecting and identifying micrometeorites). "Experiments Abstracts," a useful appendix, offers a one-line summary of each activity, along with its page number. Illustrated with line drawings, the book offers a good introduction to magnets.
