To get people to notice what it is like to be excluded from a group.
Everyone gets blind folded and then assigned an animal. The animal assignment is easy. Make up 2-4 animals that you would find on a barn, but for one person give them an odd animal (elephant, donkey, lion, ect.) After you say “go” each person tries to find their group by making their noise, and the odd one will just wonder around untill you say “stop”. Have this person talk about their feelings during and after the activity. This is a good way for everyone to visually see what it is like to be excluded from the group.
