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 guide, designed for the grade 10 through community college levels, contains a simulation game about land use decision making in a coastal zone environment. The simulation is based on a land use proposal submitted by the Weyerhaeuser Company for the development of land near the Nisqually Delta. The students are given the background to the historical development of the Nisqually Delta and relevant information from the environmental impact studies completed for the Nisqually. Through role-playing, students learn about the socio-political and economic interaction involved in a decision making process. Students are encouraged to research their roles and determine positions based on the data. (TW)
