Science Fair Projects About Water and Soil

Robert Gardner is a reliable name in children's science writing, and the experiments here — aquifers, the water cycle, pollution detection using household materials — are well-chosen and genuinely instructive for a third or fourth grader preparing a science fair project. The forty-eight pages are thin, and without independent reviews for this specific 2016 volume it is hard to call it exceptional, but it is competent and age-appropriate. Strong science students will outgrow it quickly; it is the right tool for the right moment.
