Meter Stick Experiments: Independent Practice, p. 45. Students may wish to test some other hypotheses, such as the following: (1) Reaction time is better in the morning than in the late afternoon. (2) Reaction time is better after vigorous exercise. (3) Reaction time varies with age. (4) Reaction time varies between the right hand and the left hand. An Exploration Worksheet, p. 37, is available to accompany Exploration 2.

Stage 2:

Theme Connection: Changes Over Time, ATE p. 45. Focus question: If you were to repeat the dropping and catching of the meter stick 25 times, how would your results change?
