Guiding questions ("What Are Crystals?" "Are Crystals Running Out?") introduce basic information on the topic, explaining crystals' formation, types, and locations, as well as the ways people research and use them. Scattered across the busy pages are captioned color photographs and diagrams, text boxes, and biographical and career information about scientists; a "Grow Your Own Crystals!" activity is appended. Reading list, websites. Glos., ind. Copyright 2011 Horn Book Guide Reviews.

School Library Journal Reviews 2011 April

Gr 4-6--Enhanced by plenty of photos, digital paintings, and diagrams, these examinations of rocks and related substances treat their topics in unusual detail. Each describes distinguishing characteristics, creation, history (the "rock cycle"), and human uses in central narratives with additional notes, suggestions for activities during walks outside, and occasional thumbnail biographies of scientists in side boxes. Each volume ends with a simple activity ("Make Your Own Sediment!") plus a handful of multimedia resources and places to visit. Pleasant surprises include a picture of the diamond-studded skull created by Damien Hirst in Crystals, discussions of erosion and other environmental issues in Soil, and, in Fossils, mention of "living fossils," "trace fossils" (such as those created by footprints), fossil fakes, and fossil fuels.
