Every semester when I talk to my class about group dynamics and leadership we go through a exercise called Lost at Sea. In the exercise a chartered yacht catches fire and is sinking in the middle of the ocean. Groups work together and use a rating system to determine the necessity of several recovered items. How each group rates the items determines whether or not the group will be rescued. In addition to the items a life raft that can hold four people has also been found. Before letting the groups work on the exercises I add a twist. I make them kick someone off the raft.
