This project was a role-play on the Kyoto Treaty, which dovetailed with a chapter on air pollution and global warming. Students were given a scenario handout and put into groups. A certain number of students were the Senate committee charged with investigating the merits of the treaty. The remainder of the students were various experts who were to testify to the committee. Each student highlighted those parts of the treaty that pertained to their area of interest. They were also required to research the history and current status of the treaty as pertains to the USA and other world countries. Props were required. Each student had three minutes to present their arguments and the committee had five minutes to ask questions of each expert.
