Aha! Excellent Janice VanCleave science experiment books that cover all the bases. These 200+ various science experiments represent some of the best investigations from several branches of science, including astronomy, biology, chemistry, earth science, and physics. Typically, these experiments use limited and readily available materials, and demonstrate major science concepts from each of these branches. Each experiment takes up half of a page, and includes a goal, list of materials, procedure, the results we should get, and then a short explanation of why it happens like that. Small black-and-white line illustrations demonstrate how to carry out experiments, for additional help. An excellent resource for elementary and middle school science courses - you will definitely find an experiment to take your learning beyond the lesson here. (And, for those intimidated by the title, already thinking "not in my house!" there are quite a few nice, neat simple experiments included here too). - Jess
