This manual is organized around the concept of chemical change as used to explain everyday phenomena. It concentrates on three interrelated aspects of chemical change: (l) scientific knowledge; (2) technological applications; and (3) societal issues. The unit is divided into four episodes or segments of instruction with suggested time allotments. Each episode contains a curriculum summary and a teaching approach. The curriculum summary presents content, objectives, evaluation examples keyed to the objectives, and teaching essentials. The teaching approach indicates how the flow of instruction should go to make maximum use of the manual. Appendix A contains teacher resource sheets which include demonstration instructions, experiment preparation and notes and teacher's guides to student resource sheets. Appendix B contains student resource sheets which provide students with observation record sheets for demonstrations and experiments, a list of general safety rules, and instruction sheets for experiments which include discussion questions.
