In ending the activity with a student debate, both sides of the issue should become clear to the class, together with the realization that, in cases like this, there are no easy answers. Each group works on its arguments for 10-15 minutes and each selects a main debater and a rebutter. The topic ends with a general class discussion. The worksheet is collected primarily to ensure that each student comes to the debate class with concrete thoughts about the issues.
