This curriculum guide is the fifth (Series VI) in a six-volume set that comprises the Sea Week Curriculum Series developed in Alaska. The book lends itself to the fifth-grade level but can be adapted to preschool, secondary, and adult education. Seven units contain 48 activities with worksheets that cover the following topics: (1) fish, their appearance, behavior, and classification; (2) fish species; (3) fish field studies; (4) fishing and fishing history; (5) human culture related to the seas and rivers; (6) fish as food; and (7) fisheries and the future. An introduction provides information designed to help teachers become familiar with the contents of the curriculum guide and to assist in planning. Each unit contains information on student objectives, and activity background, vocabulary, materials, and procedure. Activities engage students in interdisciplinary projects that involve the skills of classifying, identifying, comparing, computing, measuring, game playing, role playing, writing, observing, mapping, collecting data, recording data, and analyzing data. An annotated bibliography contains 168 resources. A packet of teacher reproducible worksheet masters accompanies the curriculum guide. (LZ)
