Chemicals & Reactions (Science Factory) - Hardcover

With a colorful format; easy-to-follow, step-by-step instructions; and succinct sidebars explaining why each experiment works, Richards uses a creative context to provide young science enthusiasts with a fine introduction to experimenting with chemical reactions. Requiring only common household items, the experiments are simple enough to be done independently as well as in the classroom. Their difficulty varies: more elaborate ones result in papier-machemasks, jewelry made of flour, and bubbling volcanoes. Along the way, Richards unobtrusively introduces new vocabulary that can be understood in context and is later reiterated in a cross-reference glossary. Expertly arranged photographs demonstrate each step of the processes, and diagrams illustrate the chemical reactions. A useful resource likely to provide hours of educationally sound fun.
