The Sootin books of experiments are notable for their succinct texts and their very clear progression of illustrated steps for each suggested experiment. Rocks, minerals and soil are the subjects in this book, with the usual well organized experiments recommended together with thought provoking questions about results and hints about what to watch for during and after a test. A glossary and index are provided. The Suggestions for Further Reading is a short list of other outstanding books on rocks and minerals for this age level. The ingredients for the experiments are readily available around the house items or easily acquired from hardware and lumber stores. Teachers in the early grades, short of equipment, and when low on inexpensive ideas, will find these books invaluable.
