Hand Squeeze
Collect the Data
Start with two students at the front of the room. (You're eventually going to need enough space for everyone in the class to get in a circle) Have the two students hold hands. When the timekeeper says "now" the first person should squeeze the hand of the second person who then squeezes the other hand of the first person. The last person will say "now" when she feels the hand squeeze come back to her. Record that data in the table below. Now add two more students to the circle and repeat the process, passing the hand squeeze around the circle. Record that time and repeat the process with two more students.
Continue the experiment, recording the time each time until everyone has joined the circle. Have everyone try to pass the squeeze as quickly as they feel it, maintaining the same rate of speed. If someone messes up, it's okay to disregard that time and repeat the experiment.
