Let's Go Rock Collecting

PreSchool-Grade 3. More than just the title has been changed in this updated edition of Gans's Rock Collecting (Crowell, 1984). The topics are the same? basic rock formation; the characteristics of igneous, metamorphic, and sedimentary rocks; the uses of rocks in the past (Roman roads, Egyptian pyramids) and the present (cement); and, finally, a bit about rock collecting. The excellent diagrams, full-color photographs of specimens, and minor textual changes clarify the concepts (for example, Mohs' scale of hardness) and extend the presentation. Gans barely introduces collecting rocks in the field and organizing and storing them, but the pair of youngsters featured in Keller's brightly colored illustrations certainly convey the joys of being a rock hound.?
