Read this to the class:
A Grade 5 goalie told her coach she was faster at stopping shots on her glove side than her blocker side. The coach said, "Prove it. Don't tell me, show me numbers." She wasn't sure how you even measure something as fast as a reaction. Your team's job: measure your reaction times with each hand and find out whether your writing hand is really faster.
Teams of three, with three jobs that rotate after each person has had ten catches: Dropper (holds and drops the ruler), Catcher (catches it), Recorder (reads the ruler and writes the numbers).
