This document is one of a series of role plays that focus on science-related social issues of concern in contemporary public policy formation. The role plays are designed to help students develop information-processing and decision making skills needed to deal effectively with such issues. The role plays guide students in analyzing science related social issues by applying the concepts of science, technology, conflict, values, risks, costs, benefits, decisions, and public policy. The role play presented in this manual considers the dilemma faced by a community whose landfill is nearing capacity and faced with closure. The case is set in the fictional community of Hanson. Students are assigned roles representing Hanson City Council members, scientists, government officials, Hanson residents holding various views on the issue, and other interested individuals. The students participate in a simulated city council hearing to present arguments related to the pros and cons of various ways to manage Hanson's solid waste disposal in the future. Three major alternatives are considered: (1) build a waste-to-energy incinerator, (2) build a new landfill, and (3) institute a mandatory recycling program combined with a new landfill. Students are organized into groups representing the three positions and a decision making group, the city council. Through several days of research the groups compile evidence to support their respective positions and contribute the information to a classroom resource center for the use of all groups. The culminating exercise is a public hearing. A discussion analyzing the different viewpoints and the decision making and risk management processes concludes the activity. (DK)
