This teacher's manual is one of a series designed to support "general level" program development for intermediate/junior high school science, emphasizing the relationship between science and society. The main body of the manual deals with teaching about heat in the context of home heating systems. In addition, a brief treatment of the particle model of matter is included as an optional appendix. The manual is divided into five "episodes," each a logically coherent segment of instruction. (The optional treatment of the particle model consists of two further episodes). Suggested time allotment for each episode has been indicated. Episodes are laid out in two parts. The first is a "curriculum summary," a succinct presentation of four related kinds of information: content; intent or objectives; some behaviorally stated evaluation examples (keyed to objectives); and teaching essentials. The second part is a detailed teaching approach indicating how the flow of instruction should go to make maximum use of the manual. Teacher/student resource sheets to accompany episodes in the main body of the manual are found in appendix A and appendix B respectively. Appendix C contains the two optional episodes on the particle model, and appendix D contains student resource sheets for these options. (Author/JN)
