1. Reaction Time Lab

2. Problem Question  Will the male or female Celestial students have a quicker reaction time?

3. Research  Driving  Maturity  Activities/Games/Sports  Focus  Past Experiments (2011 Celestial Data)

4. Hypothesis  A hypothesis should contain an educated guess and at least one reason why you are making that prediction.  Hypotheses should not include my or I think.  _______ will have a faster reaction time because ___________________________________ _.

5. Materials  1 Reaction Time Monitor (unit used is millisecond – ms)  4 females  4 males

6. Procedures  1. Find your partner to test  2. Make sure the person being tested has arm extended at eye level  3. Place reaction time monitor between partner’s fingers at the start mark (be sure fingers are 8 cm apart and numbers facing out)  4. Drop the reaction time monitor – partner must catch it in their fingers  5. Check and record scores  6. Repeat the test - switching tester and person being tested  7. Repeat steps #1-6 with 3 other girls and 4 boys (or vice versa)  8. Calculate the mean (average) results for each boy and each girl you tested  9. Calculate the averages for all the boys’ averages and all the girls’ averages

7. Variables/Constants  Constants: same age, strip dropped from eye level, strip dropped randomly, 8 cm for catching strip with pinching fingers, same side of strip facing catcher, 4 boys/girls  Independent Variable: gender  Dependent Variable: reaction time in ms  Control Group: none
