Check Your Pulse Biology Science Experiment

In this fun and easy biology science experiment, we’re going to explore and investigate pulse rate which is the number of times your heart beats per minute. 

Materials:

• Timer

Instructions:

1. Sit quietly for several minutes.
2. Put two fingers together and place them on either side of your neck or on your wrist. You may have to feel around for a few seconds to locate your pulse.
3. Count the number of beats for sixty seconds.
4. Try again and this time count the number of beats and multiple the total by two.
5. Now count the number of beats for fifteen seconds and times the total by four.
6. These tests should give you roughly the same number and this number is your resting pulse.
7. Now exercise for sixty seconds.
8. Count the number of beats for 60 seconds and compare it with your resting pulse.

How it Works:

Pulse rates vary from person to person and increase when you exercise and decrease when you are at rest. 

Make This A Science Project:

Try more vigorous exercise and check your pulse. Check your pulse right after waking up from a night of sleep.
