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, a vocabulary list, and a bibliography. This packet, designed for grade levels 3-4, is an introduction to life at the rocky shore. The packet introduces students to 12 common rocky shore animals including: (1) barnacles; (2) mussels; (3) limpets; (4) periwinkles; (5) shore crabs; (6) hermit crabs; (7) sea stars; (8) tidepool sculpins; (9) blennies; (10) sea anemones; (11) sea urchins; and (12) seagulls. It describes life on a rocky shore; how the animals move, gather their food, and behave at high tide and low tide. The packet emphasizes role-playing as a method of helping children understand the situation of living plants and animals. In addition, the packet is intended to help students develop appreciation for natural beauty and positive attitudes towards the preservation of seashore life. (TW)
