Procedures:

NOTE: This activity will be most effectively implemented in cooperative learning groups. Student teams should choose, or be assigned, to investigate smaller segments of the larger issues. Scientific investigation of the problem would necessarily involve many different perspectives. Student teams could concentrate on the investigation of one component of the activity. In the final presentation, teams could use a jigsaw approach, with each team presenting a different perspective on the issues.

Step 1 Place students into teams of 3 or 5.

Step 2 Distribute the Scenario and the Problem-Solving Model handouts found on the following pages. Instruct each group to read and discuss the Scenario.

Step 3 Ask them to read the Problem-Solving Model to help them develop sound advice. They should follow the steps and prepare a 5-10 minute presentation. Remind them to record all the information they research, including a bibliography, on their Student Activity Sheets.

Step 4 Assign groups presentation times.
