Using the C-ROADs World Climate simulation designed by Climate Interactive, eighth-graders are culminating their cross curricular unit on global issues by conducting a climate summit simulation. Students are role-playing the negotiations United Nation players would go through to come up with a climate treaty. After spending the past several weeks studying global issues such as climate change, and the role and structure of the United Nations, students are split into groups representing various countries or regional blocs. Their task is to negotiate agreed upon climate policies that their country/region can pursue based on realistic national and/or regional parameters (economic, social, environmental, political, etc.). The computer software will then be used to quantify the possible results of their policies and the overall treaty. This activity will test their collaboration, negotiation, communication, and problem solving skills.
