An experiment — Round 1

• Have your items with you.

• Half to the right, half to the left side of the classroom.

• You are not allowed to talk to people from the “other side.”

• You will have 10 minutes to talk to each other, ask questions, and trade items.

An experiment — Round 2

• You are no longer divided in two sides.

• You are allowed to talk/trade with everyone in the room.

Why people trade

Trade is the exchange of goods and services.
