Dedicated to the conservation and preservation of whales, dolphins, and porpoises through public education, this instructional unit for grades 5-9 provides current (1993) facts, lesson plans, activities, and conservation and preservation techniques. Interdisciplinary activities involve students in debates, critical thinking, research, and investigation of the correlations between history of whaling, whale watching, and pollution. Three sections provide a series of fact sheets and activity sheets. Activity materials are teacher reproducible for use within the purchasing teacher's classroom. Section I contains general facts and activities focusing on the difference between a whale and a fish, feeding habits, family units, whale senses, identification and behavior, and evolution. Section II includes individual fact sheets and activities for various toothed whales, and baleen whales. Section III provides problem solving fact sheets and activities concerning myths and legends (bibliography provided), migration, captivity, whaling, whale watching, stranding, and the story of three gray whales stranded off the coast of Alaska in 1988. Additional activities incorporate art, games, and language arts. Other materials include a list of eight applicable National Film Board films, a student self-evaluation form, a glossary, and a 48-item bibliography. (LZ)
