Cosmic Debate

In this activity described on pages 2-3 of the PDF, participants debate whether there there's life elsewhere in the universe. The debate requires at least two groups, and the instructions provide a worksheet to guide group discussions, and a format for running the debate: one group presents and the other responds, question by question. The worksheet could used with an individual learner instead of for a debate.
