The hypothesis is that the blood pressure will be lower while resting than when doing exercise.

You will measure the resting and exercising blood pressure of 7th grade students and compare the results.

You will need a Portable Wrist Blood Pressure Monitor, a testing room, an instruction script, a stopwatch, a metronome, and 25 subjects.

The results of the experiment showed that the student's blood pressure increased after two minutes and four minutes after exercising, but their blood pressure was higher after they rested for eight minutes than it was before they exercised at all. This suggests that the hypothesis should be accepted.

This science project is interesting because it looks at how the body responds to exercise and rest, and how it affects blood pressure.

Variations to consider include testing boys vs. girls to see which of the two genders has a higher pulse rate, and testing the subjects for a longer period of time and then having them rest for a shorter amount of time.
