Heart Rate Experiment

In Science, we have been learning about the circulatory system so we decided to conduct an experiment to see which exercises cause the highest heart rate. We picked four exercises to test and made sure it was a fair by performing each one for the same amount of time. We measured our heart rate in beats per minute (bpm) after each exercise and made sure it had gone back down to resting rate before the next exercise. Our heart rate rose after each exercise because our heart was pumping blood faster to deliver oxygen to our body.
