The document is a guide to a 9th and 10th grade industrial education course investigating the total system of power--how man controls, converts, transmits, and uses energy; the rationale is that if one is to learn of the total system of industry, the subsystem of power must be investigated. The guide provides a "body of knowledge" chart delineating the content possibilities for any power-related course at any level of instruction, orientation suggestions, safety instruction, and introductory activities such as suggested teacher demonstrations and discussions of career possibilities. Lesson plans covering five major topics comprise the bulk of the guide; objectives, equipment, resources, and the procedure for learning activities are provided for: (1) power conversion (26 days); (2) mechanical transmission (5 days); (3) fluid transmission (8 days); (4) electrical transmission (8 days); (5) synthesis of power systems (a single "synthesis problem" occupies the students for 14 days). Appended are a definition of behavioral objectives; a pretest, posttest, and attitude inventory, with answer sheets; an equipment list; and a bibliography. The guide is one of the outcomes of the Secondary Exploration of Technology (SET) Project. (AJ)
