Question: Does blood pressure vary by different activities?

Hypothesis: Blood pressure does vary by different activities.

Experiment: I performed different activities and measured my blood pressure and noted the findings.

Analysis: I looked at how the numbers varied. When I was reading, I had 107/63 and when I was sprinting, my pressure went up to 127/80. So my hypothesis was correct.

Conclusion: Blolod pressure does vary after different activities. Blood pressure is lower when you relax than when you are physically active.
