Class is divided into 8 groups. Each group gets a sense
In your group:

• Make a list of arguments: Why is your sense the most important or best sense
• Give examples of situations in which your sense is important, amazing, fun, lifesaving, etc.
• Give examples of why living without the sense would be hard, dangerous, unappealing, boring, etc.
