See attached PDF.

In this lab we will learn how to measure blood pressure and pulse rate, and examine different factors and conditions that affect blood pressure and pulse.

Prior to Lab Day:

Review the attached PDF to familiarize yourself with the general idea of the lab.

extra credit: Complete the Pre-lab assignment (circulatory physiology) on a separate sheet or google doc and submit on lab day. Complete bullet point summaries, vocabulary definitions, and answer questions at the end.

Lab Day:

1. You will work in your assigned lab groups.

2. Execute the procedure for 10A and 10B of the handout and complete the data tables.

3. In the next phase of the lab, you will design your own experiments to measure the effects of various conditions or factors that might affect heart rate and blood pressure.

4. Before you begin, discuss hypotheses with your group and agree on a best hypothesis.

Examples: If an individual listens to heavy metal music then their heart rate will increase. You can test whatever you like within reason and appropriateness (i.e. different types of music - classical, hip hop, reggae, etc. different types of physical activity - walking, running, jumping, etc. different stressors - yelling, any number of competitive or stressful games, etc.)

5. Execute your experiment.

6. Share data, record class data.

7. When finished, immediately begin writing up a formal lab report in your actual lab notebook of what you did.

a. Title and date

b. Problem: What factors affect blood pressure and pulse?

c. Hypothesis: See above. If... then...

d. Experimental Design: brief description of what you did and the conditions tested.

e. Materials: list the items used in the lab.

f. Procedure: Give a summary of the procedure and set up.

g. Data collection: tables, recorded observations, etc. for your individual group and the class.

h. Analysis: graphs (for tests 5 and 6) and comments. state which parameters tested in the class increased pulse the most/least.

i. Conclusion: discussion of your observations and results...

address the parameters that increased pulse the most/least, and reasons WHY this would be the case.

address physical versus psychological parameters (if applicable).

address differences in the individuals involved in testing (sex, age, fitness level, lifestyle, etc.)

what implications does this have in real life (stress/relaxation/physical activity/lifestyle, etc.)

relate to information we covered in class.

j. Post-lab: conclusion questions on the handout.

8. Turn your in lab notebook by the assigned date for review by Dr. Kostenko.
