Description
My science fair groupís experiment had to do with the heart beat. We had kids walk up and down stairs for 3 minutes and recorded the heartbeat. Then we had them do the same thing 2 more times, except that music was playing (rock and classical) while they were running. My hypothesis was that music would not have an effect, but it raised the heartbeat. My favorite part of science fair is looking at other peopleís experiments.
