Fifth grade students compare and evaluate their attitudes, values, and concepts regarding the interrelatedness of man, his social, cultural, and bio physical environment, and examine decisions, plans, and actions affecting environmental quality. The purpose of this interdisciplinary curriculum guide is to combine text material with the wealth of resources available in each community in order to reinforce and contribute to environmental literacy. Curriculum is presented in outline form providing for each of the seven units' major concepts and learning activities, vocabulary aids, experiments, discussion questions, and suggested readings. The first half of the book focuses on science education offering units on water, oceanography, and plants. The second half proposes to develop an understanding of how men used the natural resources of this country to supply their needs, and in so doing, created environmental problems. From this historical perspective it is hoped that students will develop an environmental awareness and a sense of responsibility for their own actions. Units are included on colonization, westward expansion, landscape architecture, and selected American Indians. Two plays on environmental issues are included. (Author/SJM)
