Twelve energy lessons developed for use by senior high school students are presented. These lessons are designed to help students become more aware of the energy choices that they must make in the present and for the future and to understand that the costs of maintaining a specific standard of living and thriving national economy can be controlled with wise energy choices and decisions. Each lesson includes: statement of concept(s) fostered; time requirement; list of materials needed; rationale; the economics concepts and/or topics contained in the lessons; instructional objectives; suggested teaching procedure; suggested evaluation strategy; additional activities; and (when applicable) student handouts, worksheets, and transparency masters. Among the concepts fostered in the lessons are: productive and natural resources; consumption; opportunity costs; substitutes; externalities; determinants of and changes in supply and demand; and the price mechanism. Included is a list of free and inexpensive materials by these subject areas: coal; conservation; economics and energy; electricity; energy (general); energy education; environment; natural gas; nuclear energy; petroleum; renewable energy sources; and synthetic fuels. Also included is a glossary of important energy and economics terms. (JN)
