The ocean affects all of our lives. Therefore, awareness of and information about the interconnections between humans and oceans are prerequisites to making sound decisions for the future. Project ORCA (Ocean Related Curriculum Activities) has developed interdisciplinary curriculum materials designed to meet the needs of students and teachers living in Washington State. Each activity packet provides the teacher with a set of lessons dealing with a particular topic related to the oceans. Included are student worksheets, lesson plans, and a bibliography. This activity packet, designed for the junior high school through community college levels, introduces students to the major themes of marine biology. Through classroom, laboratory, and field trip activities, it is intended that students develop an understanding of structural adaptation, behavioral adaptation, zonation, and habitat. (TW)
