Chemical Demonstrations: A Sourcebook for Teachers. Volume 2.

This book contains 112 classroom demonstrations intended to be used with any introductory chemistry program. These demonstrations were selected in an effort to provide simple, safe, effective and enjoyable experiences for the class. In addition, they are intended to be used to introduce many of the major concepts in chemistry. The demonstrations involve color changes, gas evolution, precipitate formation, smoke, fire, and other obvious or dramatic chemical changes. The guide is organized into 11 major sections including: (1) introducing chemistry; (2) physical changes; (3) reactions involving gases; (4) reactions of some elements; (5) transition metals and complex ions; (6) chemical bonding; (7) energy changes; (8) solutions and solubility; (9) kinetics and equilibrium; (10) acids and bases; and (11) oxidation and reduction reactions. Appendices include an equipment and reagent list and detailed safety and disposal instructions. (TW)
