The two separate manuals focus on environmental issues of interest to secondary students. An introductory unit deals with basic ecology and is followed by another unit that explores man's ethic toward the use of environment. Emphasis is upon two major ecological conflicts: one over the use of a wilderness area, and the other over the use of living and non-living resources of the oceans. In the third unit, students examine the right of Walt Disney productions to develop the Mineral King area of the Sequoia National Forest in California into a resort. Questions over use of the oceans are examined in the last unit, with students discussing a variety of issues ranging from oil spills and fishing rights to the division of the wealth in the oceans. Inductive methods encourage students to discover controversy through the examination and discussion of issues and through various suggested activities. Problem solving and concept learning are emphasized. The teaching guide is arranged into four major units containing several lesson plans--each including rationale, objectives, student assignment, and procedures. The lessons in the student workbook are coordinated with the guide. The teacher is provided with a tentative time schedule allowing the study to range from nine weeks to a full semesters work. (SJM)
