    The document is an activity worksheet about measuring heart rate. It instructs students to take their pulse at rest and after exercise to see how it changes. It explains that the heart has four chambers and acts as a double pump. It provides step-by-step instructions to take the pulse for different time periods and calculate the heart rate. Students are asked to record their observations and answer questions about the difference between their resting and exercising heart rates and how to interpret these rates.

    Activity 6
    The Rhythm of My Heart
    Objectives:
     Measure and describe your pulse (heart rate) after several different activities
     Explain how to use different time intervals to measure your heart rate
    Materials:
    Stopwatch / timer Data Logbook
    KEY CONCEPTS
    The heart is a hollow muscular organ, about the size of your fist, which is located in the center of your chest between the
    lungs. It is a double pump that pumps on the left and right sides. Every side is divided into two chambers, the atrium and the
    ventricle, each of which has left and right portion, totaling to four chambers altogether. The top chamber is the atrium (plural:
    atria). The bottom chamber is called the ventricle. The valve acts as a one-way door, allowing blood to flow either forward into
    the next chamber, or out of the heart.

    Procedure:
    1. Sit quietly for a few minutes before beginning the activity.
    2. When you are ready, place your first two fingers either on your neck or on the inside of your wrist and locate your pulse.
    3. Once you find your pulse, start the watch, and for 60 seconds, count the number of beats you feel. That is your pulse.
    4. Try the experiment again, but this time count for only 30 seconds. When you are done, multiply your count by two. Compare
    your pulses.
    5. Repeat by counting for 15 seconds and multiplying your count by four, then counting for 10 seconds and multiplying by six,
    and so on.
    6. Once you have determined your resting pulse, go to a place where you can exercise vigorously for at least one minute.
    Exercise of this sort might include a fast jog, running stairs, skipping rope, or doing pushups. When you are done, you should
    be breathing hard.
    7. Choose the length of the test you wish to perform and find your pulse again.
    8. Compare your resting pulse with your pulse after exercise.
    9. After the activity, record your observations and answer the guide questions.
    Guide Questions:
    Q20. What was your calculated resting pulse?
    _____________________________________________________________________________________
    Q21. What was your pulse after exercising?
    _____________________________________________________________________________________
    Q22. How would you differentiate your heart rates before and after exercising?
    _____________________________________________________________________________________
    Q23. What is the advantage of timing for a full minute to find your pulse?
    _____________________________________________________________________________________
    If you know that you have a serious medical condition, do not perform this activity.
    Q24. What is the advantage of timing over a shorter period of time, especially when you have just finished exercising?
    ___________________________________________________________________________________
    Q25. According to statistics, the maximum heart rate should be 220 minus a person's age. How would you interpret your
    highest heart rate in relation to that given number?
