Sami's Science Project

My first science project involved investigating pulse rate. I took 15 subjects and took their pulse rate. I did this by putting my finger up to the wrist or neck, finding the pulse and counting. I counted how many beats I felt in ten seconds and then multiplied it by six. I then took everyone on a walk around our school. Halfway through, I took the pulse again, and then again at the end of the walk. I found the rate is higher halfway through the walk than before and highest after the walk was over. I also found that girls have a higher pulse rate. If I did this experiment again, I would have the same amount of girls as boys. I would also have everyone rest for the same amount of time before taking the resting pulse rate.
