Title: Finding a Person's Breathing Rate at Different Depths.

 

Problem Statement: How does the breathing rate compare and contrast from each person while swimming at different depths of water?

 

Hypothesis: To see our hypothesis please click here.

 

Method and Materials:

Four people: (Three girls and one boy all wearing their scuba diving equipment)
Girl #1: Emma Huser (Person #1)
Girl #2: Caitlin Tortorici (Person #2)
Girl #3: Ashley Willson (Person # 3)
Boy #1: Dylan Chapgier (Person #4)

-One piece of rope/string marked every five feet
-One clipboard
-Three overhead projector sheets
-A group of oil pastels
-One watch (water proof)
-One disposable, water proof, camera
-Diving Equipment (Including mask and snorkel)

Step One: Take person number one and have them breathe outside the water with their
diving equipment on, for one minute.

Step Two: While the person is breathing, keep track of how many breaths the person takes.
Record your results using the overhead projector sheets, on the clipboard,
writing with the group of oil pastels.

Step Three: Take person number one and have him/her go underwater to the five-foot
marker on the rope have him/her breathe for one minute and then record the
results.

Step Four: Then, have person number one go down to the ten-foot marker, let him/her
breathe for one minute; and record the results.

Step Five: Move person number one to the fifteen-foot marker and have him/her breathe for
the final minute, then record the results.

Step Six: After completing steps one through five successfully, repeat the five steps using
person number two in place of person number.

Step Seven: Then replace person number two with person number three and have him/her
repeat steps one through five.

Step Eight: And finally, take the last person, person number four, and have him/her repeat
steps one through five; record the results.

* We are able to determine how many breaths per minute of the person being tested by listening to the sound of them inhaling and exhaling on land. While they are underwater, we will be able to get our results by counting how many times the bubbles come up from their tanks, exhaling.

Conclusion: The breathing rate of each person differs depending on his or her weight,
height how active they are, and other personal information. As the person goes underwater their breathing rate should slow. However, because each person has a different pattern of breathing their breathing rate may fluctuate, stay the same, increase, or decrease when going to larger depth underwater.
