Using numerical data to describe and compare objects and events may seem difficult or something that is hard to do, but, in fact, it is very simple. For this activity, we will count the number of times our heart beats in one minute. Then, we will record that number and compare our number with a partner’s number to see how they differ. We will count our heart beat on two separate occasions to see how they differ. Once will be at rest, and the other time will be after we did 30 jumping jacks.
To check your heart rate you must place your fore finger and your middle finger on one side of your neck and find your pulse. After you do this, you will need to have your partner time you for 30 seconds while you count the number of times that your heart beats. Then, you will multiply that number by 2 and that will tell you how many times you hear beats per minute.
