Gr 6 Up-Although Gardner covers some familiar ground in these two books, he brings fresh perspectives that make both volumes valuable contributions. In Electricity, he presents 17 activities dealing with static electricity, magnetism, electromagnetism, and basic electrical properties such as simple circuits. Most of these demonstrations are well known and similar to those found in Janice Van Cleave's Electricity (John Wiley, 1994). However, Gardner fits his demonstrations into a historical narrative that is sprinkled with some contemporary gee-whiz tidbits-for example, the role of static electricity in photocopiers, and magnetism as a possible cause of whales beaching themselves. Optics offers 15 activities that explore topics such as refraction, lenses, and color photography. The text dwells primarily on the underlying physics, along with descriptions of the workings of the human eye. In both titles, explanations of what happened in the demonstrations become part of the discussion and, as a result, concepts build upon one another. Some of the items required for the projects are more likely to be found in schools rather than homes, especially in Optics, which calls for a small laser. Optics is also tougher to read, but the author competently explicates a number of difficult subjects without resorting to mathematics. Attractive, full-color drawings and photographs illustrate the set-ups for most of the activities. A glossary along with lists of materials and English and metric units are found at the end of each book; but there are no suggestions for further reading.-Alan Newman, American Chemical Society, Washington, DC
