One of a series of social studies units designed to develop the reading and writing skills of low achievers, this student activity book focuses on the theme of energy. The unit can be used for high school classes, individual study in alternative and continuing high schools, and adult education classes. Separate sections cover early sources of energy, present-day sources of energy, energy waste in the United States, energy and the environment, conservation, and future sources of energy. Each section consists of a reading stressing vocabulary development and recognition of sounds. Additional sections contain definitions of the more important energy words, cartoons illustrating energy supply and demand in the United States, and an energy I.Q. test. Readings in the appendix illustrate the problems of pollution, nuclear energy, and the incident at Three Mile Island. Reading comprehension exercises are included. (LP)
