Since the end of World War II and the onset of the "new age," nuclear technology has remained high on the world's agenda as questions regarding sovereignty and the balance of power, control of the development and spread of nuclear weapons, non-military uses for nuclear technology, and nuclear safety are debated among and within nations. The "club" of nuclear nations has grown dramatically and the number of nuclear weapons has grown from zero to over 60,000 in just over 50 years. This curriculum unit examines the development and use of nuclear technology through six main activities. Each activity allows students to explore a case study that looks at possible scenarios for the control of nuclear technology and the challenges that policy makers face with respect to nuclear technology. The unit's activities help students develop a basic understanding and issues of nuclear technology. The unit's goal's are to review the history of the development and spread of nuclear technology; familiarize students with treaties and agreements regarding nuclear technology; consider options for controlling nuclear technology; and make connections between the students' own experiences with nuclear issues and the presentations in the unit. Following preparatory activities, the six activities are: (1) "supranational organizations"; (2) "nation-states"; (3) "everyone"; (4) "physicists/scientists"; (5) "business and nuclear industry"; and (6) "no one." A closing activity, six appendixes, and bibliography and resources conclude the unit. (BT)
