Lab Investigation: How Healthy Are You?
Purpose:
To determine how healthy you are and compare your vital signs (pulse and respiratory rates, blood
pressure and vital capacity) before and after exercise. You will also compare your vital signs with your
classmate’s and with the standards for your age group.
Prediction/Hypothesis:
Formulate a hypothesis. Your hypothesis should be clearly worded and indicate your understanding of
the purpose of this activity. State how healthy you are and predict how you think exercise will affect
your pulse and respiratory rates, blood pressure and vital capacity.
Materials:
Rubbing alcohol, cotton balls, blood pressure wrist cuff, stop watch, spirometer, cardboard tube
Procedure:
1. With your partner, write out the steps required to measure your pulse and respiratory rates,
blood pressure and vital capacity before and after 5 minutes of brisk exercise. Use your textbook
pages 270 and 299 as a reference.
2. Be sure to include any safety measures to be followed.
3. Be sure to include an observation table to record your results and your partner’s results.
Observations:
Complete observation table. Be sure to include room to record your partner’s results.
Analysis:
How do your behaviour choices and habits relating to exercise, diet, rest and other choices (such as
smoking and alcohol) affect your circulatory and respiratory systems? How do your rates compare with
your classmates? How do these rates compare with the standards for your age group?
Points to discuss:
 Do you do at least 20 to 30 minutes of aerobic physical activity three times a week? Did this
show in your data?
 Do you eat 3 nutritionally balanced meals each day? Did this show in your data?
 Do you avoid harmful substances such as tobacco, alcohol or other drugs? Did this show in your
data?
Conclusions:
State how exercise affected your pulse and respiratory rates, blood pressure and vital capacity. Was
your hypothesis supported? Explain. Describe 2 possible sources of error.
