As a part of the unit materials in the series produced by the Australian Science Education Project, this teacher edition is primarily composed of three parts: a core, a number of options, and test forms. The core is concerned with seashores, wind, waves, life on seashores, and rocky shore ecosystems. Options are given under the headings: Pollution of the Seashore, Wave Problems for Engineers, Beach Erosion, Vanishing Beaches, Cycles of Coastal Erosion, and The Great Barrier Reef. Students are asked to do one of the first three parts of the core, but the fourth part is required for all students. Behavioral objectives are given to facilitate students' acquisition of outcomes. Also included are recommendations for use of the unit, an introduction to audio-visual aids, lists of references and equipment, hints on excursion and group discussion, and keys to questions and tests. The accompanying record book is intended for students to record observations and write answers. (CC)
