Do boys or girls have a faster reaction time?

on February 20, 2013

4th grade students dropped a ruler and recorded the partner’s reaction time in seconds.  We compared the boys’ times to the girls’ times in the class.  One section got the same averages for both genders, while another section had the boys reaction time significantly faster than the girls.

This encouraged a debate in the class about data collection.  Students discussed how the there needs to be a standard height dropped and distance between the ruler and the student catcher.  There are lots of different variables that may affect the outcome of the experiment.  There are more variables to test in the class such as age of student.  Bringing gender into the discussion helped to illustrate the importance of fairness when testing an idea scientifically.

    What a great way to explain those concepts. I’ve been trying to explain these things to my sixth grader, who has been somewhat grouchy about the need for precision in science lab this year…..

      I am so glad I am trying these experiments with the fourth grade. Naomi really dives right into the data collection and experimentation. The kids are ready for science at this age!
