This item is needed: watch with a second hand

Follow these steps.

1. Hold the first two fingers of your right hand lightly against the inside of your left wrist. Another good place to find a pulse is on your neck, to one side of the voice box.

2. Feel the soft beat beneath your fingers.

3. Use the watch with a second hand to count the number of beats in one minute. Record the number of beats per minute.

4. Using the watch with the second hand, count the number of beats in fifteen seconds. Multiply your result times 4 for the number of beats per minute. Record.

5. Count the number of beats in ten seconds. Multiply your result times six for the number of beats per minute and record.

6. Take the pulse of one of your parents or friends. Record the number of beats per minute using the minute method, the fifteen second method, and the ten second method. Record the results.

7. Run in place with your friend for one minute.

8. Take both of your pulses again. Record them.



Write a short scientific summary comprising 150 words of your findings from this investigation. Be sure to answer the questions below as well as include 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.

yes some one who is larger than you.

tends to have a slower heart rate.

Body size normally does not increase your heart rate. However, if you are obese, you may see a higher resting heart rate.

I did have a slight change at one point but not significant

Because it saves you time but not only that It's because after time your

heart rate will drop and sow down so you can't get an accurate enough score

After I ran my heart rate shot up because During exercise, your heart typically beats faster so that more blood gets out to your body.

It's very important that you measure your heart rate carefully so you don't

pass out or damage your body.
