This exercise should also reveal who in the group is serious, doesn t care, is a leader, etc. Cut out obituaries from a newspaper. In effect, give them the asignment then leave them alone. When they are done, have one person from each group read the obit aloud to the class. This should give them some idea of who won t work well without pressure, who will work hard all the time, who takes charge when it simply has to get done.
Some groups work well all time, but most work very differently.
One could also follow up with journal assignment asking them to write their own obits.
