Homeostasis Lab

We did a lab that showed homeostasis taking place. There were many different changes that you could study to demonstrate homeostasis. The way my group picked was our heartbeat. We decided to swim and run. Remember homeostasis is  is the property of a system in which variables are regulated so that internal conditions remain stable and relatively constant.

Materials:

• Heart rate monitor
• swimming pool
• stairs
• pencil
• paper

Procedure:

 On the first day we did swimming and I, Leah, swam a total of 5 laps. The first 3 laps my heart rate went up by 40%, at 4 laps it went up by 66%, and at 5 laps I was at 53%. Christian also swam and her results were: 3 laps a rise of 4%, 4 laps a rise of 18%, 5 laps a rise of 6%. The next day we both ran stairs. Here are Christians results: 2 stairs a rise of 38%, 4 stairs a rise of 17%, and 6 stairs a rise of 21%. Here are my results: 2 stairs a rise of 53%, 4 stairs a rise of 19%, and 6 stairs a rise of 45%. 

Conclusion:

Everytime we collected data, the second result always went down then the third went right back up. I think this is because after the first time our body was going to homeostasis and thats why the second result was less. When we did something the third time it went right back up, but not by to much. Down below are graphs of the data we collected.
