The moderator calls out a question; teens should go around the room, looking for people that share a similar answer to theirs. Those who have similar answers should form a group.
After one minute, tell everyone to stop and the moderator asks each group to call out their answers.
See which groups are the largest and which are the smallest. Ask the smaller groups if they have less people because they weren’t fast enough to find others or because their answer is different from everyone else. Ask the larger groups if anyone joined just because they were following their friends around.
Choose a new moderator and repeat.
