Blood Pressure Science Project
Blood Pressure Science Project: Colors and Blood Pressure
This blood pressure science project determines if colors have an affect on blood pressure.Background:
Research information on blood pressure and color perception. Answer the following questions: What is blood pressure? How is blood pressure determined? What factors cause an increase or decrease in blood pressure? Can colors affect blood pressure? Do certain colors induce stress? Can colors affect pulse rate?
Hypothesis:
From your research you will determine if colors have an affect on blood pressure. The colors that will be used in this experiment are: blue, red, green, orange, purple, black, and white.
Materials: (Adult supervision of kids is always recommended.)
- Suggested kit: Flashing Lite Cube - You will need 3 cubes.
Scientifics Online: 7 Color Flashing Lite Cube
Science Kit: 7 Color Flashing Lite Cube
- Blood pressure and pulse monitor - Suggested monitors:
Scientifics Online: Wrist Blood Pressure/Pulse Monitor
- Construction paper - black sheet and white sheet
- Drinking glass
- Towel
- Tape
- A number of human participants; the more the better
- Comfortable chair or sofa
- Table
1. Gather materials needed for your blood pressure science project experiment. List all of the materials used including anything used in your kits.
2. Follow the instructions for properly operating your flashing Lite Cubes and blood pressure monitor product.
3. Choose a dimly lit room for your experiment. Arrange the furniture in the room so that a table is positioned in front of a comfortable chair or sofa.
4. Fill the glass with water until it is half full. Set the Lite Cubes to the clear setting and place them in the glass. Place the glass on the table.
5. Ask one of your participants to sit in the chair while you place the blood pressure monitoring system on his/her arm or wrist. This monitor will remain in place during the experiment.
6. Ask your participant to look at the glass for about 3 minutes. After 3 minutes, take the participant's blood pressure (BP) and pulse readings while he/she is looking at the glass. Record the starting BP and pulse.
7. Remove the Lite Cubes from the glass and change the setting to the blue color. Place the cubes back into the glass, dry your hands with the towel, and set the glass on the table.
8. Ask your participant to look at the glass for about 3 minutes. Take the participant's BP and pulse readings after each minute while he/she is looking at the glass. Record each BP and pulse reading.
9. Repeat steps (7-8) for the remaining colors. For white, put the Lite Cubes on the clear setting and wrap a sheet of white construction paper around the glass. Use tape to hold the construction paper in place. For black, remove the Lite Cubes and wrap a sheet of black construction paper around the glass.
10. Repeat steps (4-9) for the remaining participants in your study. Calculate and record the average BP and pulse readings for each participant. Also calculate and record the average BP and pulse readings for all participants.

Results:
Compare the results for your blood pressure science project experiment. Did any of the colors affect the blood pressures of your participants? If so, how? Were there any differences between the participants in age, gender, etc.? Was a particular group more affected by the colors than others (ex. males or females, younger or older)? Graph and chart your data.
Conclusion:
Summarize what happened in your project experiment based on your results. Explain patterns in your data. Did your data support your hypothesis? If not, explain why. Evaluate your project and make suggestions for improvements.
Project Display:
Now that you have completed your science project experiment, it is time to showcase all of your hard work. For information on how to display your science fair project, see Science Project Displays.
