Despite its cold and barren appearance, Alaska's tundra supports a surprising variety of insects, birds, and mammals. In this document, three teacher's guides (for primary, upper elementary, and junior and senior high schools) and a supplementary resource packet present a comprehensive unit of study on Alaska's living tundra. The five lessons in each guide cover the nature of tundra environments, types of tundra and the organisms present, special survival adaptations of tundra wildlife, interconnections of the tundra ecosystem, and human use of and effects on the tundra. Guides include teacher background information, a glossary, classroom activities, ideas for curriculum integration, worksheets for student review or evaluation, and references. Class activities develop or improve students' skills and knowledge in science, social studies, language arts, mathematics, or art. The supplement contains summaries of information about permafrost, topography of the tundra, and tundra wildlife, as well as over 100 wildlife cards with illustrations and text, presenting the most common or easily recognized plants, animals, fungi, and microscopic organisms found in Alaskan tundra.
