“Are You Healthy?”
Purpose:
Station 1: What is the relationship between health and blood pressure?
Station 2: What is the effect of exercise on heart rate?
Station 3: What is the effect of exercise on respiration?
Hypothesis:
Station 1: If I compare my blood pressure with the chart then I will determine that I am healthy or Unhealthy.
Station 2: If I exercise then my heart rate will increase.
Station 3: If I exercise my respiration will increase.
Materials:
Sphygmomanometer
Stethoscope
Test Tube With Bromothymol Blue
Straw
Procedures/Methods:
Station 1: You will measure your partner’s blood pressure with a Sphygmomanometer. Write down systolic and diastolic blood pressures.
Station 2: Using the wrist or neck method you will find your resting heart rate and then check your active rate after you exercised for a minute.
Station 3: You will check your exchange rate before and after exercising. Before exercising you will blow air through a straw into test-tube A and record how long it takes to change color. Then exercise for one minute then blow through test-tube B and record how long it takes to change color.

Conclusion:
Paragraph 1 The purpose of this experience was to see the relationship between health and blood pressure. Also, too see the effect exercise has on heart rate and the effect of exercise on respiration. My hypothesis was correct because when I compared my blood pressure with the chart I determined if I was healthy or unhealthy. When I exercised my heart rate increased and my respiration increased as well. Your artery is used to measure your pulse because it is what transports all materials to the lungs and back to the heart. While my resting pulse increased by almost half after I exercised, it proves that exercise
