Gr 3-5-An important moment in the history of geology or a fictional child's encounter with the world of rocks serves as a lively opener in these titles, and is followed by clear information on related science and scientists. Fossils is the best book, including as it does numerous close up, bright images of dinosaurs and other extinct creatures; explanations of the ways in which the rocks are formed; and a discussion of fossil fuels. Without mentioning political issues, the book debunks creationist arguments by explaining why there are gaps in the fossil record and the evidence that birds descended from reptiles. Soils is also useful, as it boasts better photographs of different soil types than are commonly seen in books of this type, including a particularly interesting photo of a series of soil horizons and a case study involving soil removal at the Leaning Tower of Pisa. Gems, Minerals, and Ores are ripe for combining into one longer volume. The material is available elsewhere, and the images are pedestrian. All of the titles include a craft, such as creating a fossil or making metamorphic rocks, that involves bought materials and requires adult assistance (a fact that is mentioned as the first step in the instructions).[Page 96].
