This curriculum guide is the second (Series II) in a six-volume set that comprises the Sea Week Curriculum Series developed in Alaska. This second book in the series lends itself to the first-grade level but can be adapted to preschool, secondary, and adult education. Nine units contain 30 activities with worksheets that cover the following topics: (1) introduction to marine invertebrates; (2) marine invertebrate species; (3) beach field studies; (4) freshwater invertebrates; (5) fish; (6) amphibians; (7) marine mammals; (8) freshwater mammals; and (9) aquatic habitats. 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 observing, identifying, reading, writing, coloring, numbering, counting, comparing, investigating, composing songs, role playing, and game playing. An annotated bibliography contains 239 resources divided according to unit. A packet of teacher reproducible worksheet masters accompanies the curriculum guide. (LZ)
