Write a short scientific summary comprising 150 words of your findings from this investigation. Be sure to answer the questions below as well as including your own data and reflections. How many times did your heartbeat in one minute when you took your own pulse?

How many times did your friend or parent's heartbeat in one minute?

If you took the pulse of someone who was a different size or age than you, did you notice a difference in heart rates?

Body size, age, and fitness level are factors in heart rate. Why is this?

When you counted heartbeats over periods of ten, fifteen, and sixty seconds, did you notice differences in the final heart rates? If so, was the difference significant?

Why is the ten- or fifteen-second method of taking a pulseless accurate than counting the beats in an entire minute?

After you ran in place, what happened to your heart rates? Why do you think this took place?

What did you find out from this experiment? Be thoughtful in your answer.
