One of a set of high school curricula on nuclear issues, this 10-day social studies unit helps students understand the interrelationship of economics, the arms race, military spending, and the threat of nuclear war. Activities such as role plays, discussion, brainstorming, and problem solving develop students' abilities to evaluate issues and information in order to make educated decisions. Topics covered in the 10 lessons are conflict and resolution, war and negotiation, countries currently at war, effects of a nuclear explosion, Hiroshima, perceptions of the Soviet Union, national security, tax allocation, military spending and the economy, and the quality of life. In a culminating activity, students are encouraged to express their feelings and explore ways they can affect society. Each lesson includes a plan sheet, readings, student activities, worksheets, and a homework assignment. Additional materials include an evaluation form; a bibliography; and lists of informational, instructional, and audiovisual materials. (LP)
