This instructional unit for the second grade is intended to stimulate the child's curiosity to know more and to grasp relationships through a blending of ideas about energy with a study of the effect of the use of energy on the livelihood of people in the community. There are four lessons in the unit. The first, Introduction to Energy, deals with the question, "What is energy and energy conservation?" The second lesson, Community Workers Who Work Directly With the Sources of Energy, discusses farmers, grocers, food processors, oil workers, gas station attendants, and meter readers. The third lesson is entitled Community Workers Whose Work Depends on a Continual Supply of Energy. The fourth lesson is Community Workers Who Make Decisions About Energy. Each lesson contains complete teacher and student materials including background readings, objectives, teaching strategies, and suggestions for extending the learning outside the classroom. (BB)
