This teacher's guide and its accompanying supplement were prepared for use with the U.S. Department of Energy's Dinosaurs and Power Plants, a publication designed for students in grades 5-8 about the history, detection, extraction, transportation, use, environmental problem/solutions, and future of fossil energy. The study of energy science shows the close interrelationships of all creatures and phenomena. Therefore, attempts have been made to incorporate information in all three documents (publication, teacher's guide, and supplement) that involves history, geography, geology, biology, language studies, etc. Although the text of the teacher's guide closely follows "Dinosaurs and Power Plants," some additional or more explicative information is included in the guide for teachers to use in classroom discussions. The suggested lesson introduction methods and follow-up activities encourage the student to use or develop skills of leadership, deduction, communication, organization, socialization, observation, interpretation, and creativity. The guide is divided into five lessons about fossil fuels: (1) "Importance and Formation"; (2) "Discoveries and Uses"; (3) "Detection, Extraction, and Transportation"; (4) "Environmental Problems/Solutions"; and (5) "Energy for the Future." The first page of each lesson plan shows a summary of the key questions to be covered, the lesson objectives, time allotment, and suggested materials to be used. The second (and sometimes third) page of each lesson plan suggests one or two methods for introducing the lesson topic. Key questions are answered by the italicized text seen with brackets on the right side of the page. The graphics point out a picture or series of pictures that can be used with a particular portion of the lesson text. Boxes are used in the guide to provide additional information, offer suggestions for activities or graphics, or show needed materials. Student activities are offered at the end of each lesson plan. "Student Activity Options" are listed that can be performed in class at the time of the lesson. "Student Follow-Up or Extension Options" that can be done as homework, classroom activities separate from the lesson, or as refresher activities in the days or months following the lesson series are also provided. The supplement contains 8 1/2" x 11" versions of the graphics and materials mentioned in the teacher's guide. The materials in the supplement are presented in the five lesson plan format followed in the teacher's guide. Materials in the supplement may be used for vu-graphs, bulletin boards, reproduction for individual student use, or any classroom activity. (KR)
