The current energy situation in the United States is a web of complicated and related elements. This document attempts to address some of these variables in presenting interdisciplinary energy lessons taken from instructional packets previously developed by the Project for an Energy-Enriched Curriculum (PEEC). The 19 physical science lessons include background information, teaching suggestions, student handouts and activities. Each lesson also contains the objectives of the lesson, target audience, a suggested time allotment, and sources for more information. Lesson topics include the following: (1) the laws of thermodynamics; (2) nuclear power; (3) energy resources and technologies; (4) biomass conversion processes; (5) synfuels produced from coal; (6) automobile engines; (7) new inventions and improvements; (8) energy quality; (9) appropriate technologies; (10) the greenhouse effect; (11) global temperature changes and possible effects; and (12) the use of water in coal and oil shale production, and in thermoelectric power plants. The activities are intended to be infused into existing courses in chemistry, physics, and geology. (TW)
