Homeostasis
For the third project in stem, we researched homeostasis and how the body maintains it. We were tasked to find specific elements of the body and see how they are maintained through homeostasis. My group and I decided to focus on the respiratory system. For our expirement, we had both boys and girls run various lengths so we could measure their breathing rates and how long it takes to return to them.
Content
Homeostasis- how the body maintains itself through various interdepentent cycles
Respiratory System- the set of organs that allows a person to breathe and exchange oxygen and carbon dioxide throughout the body
Resting Breathing Rate- the number of times a person inhales within a minute
Gas Exchange- The primary function of the lungs; transfer of oxygen from inhaled air into the blood and the transfer of carbon dioxide from the blood into the exhaled air
Lungs- responsible for getting oxygen into the body, and exhaling "toxins"
Oxygen- a gas in the air that we need to survive
Carbon Dioxide- waste product of our bodies

Results
Our results concluded that no matter the gender, the more physical exertion the longer it takes to return to resting breathing rate. Participant 1 had a resting breathing rate of 24 breaths per minute and took 1 minute to get back to resting breathing rate after running the 100m, 2.2 mins after 200m and 3 mins after 400m. Participant 2 had a resting breathing rate of 35 and took 1 minute after 100m, 2 minutes after 200m and 2.5 minutes after 400 m. Participant 3 had a resting breathing rate of 20, and participant 4 had a resting breathing rate of 21.They both took 1.5 minutes after running the 100m, 2 after 200m, and 2.5 after 400m to return to their resting breathing rate. Each time we added more distance, we found that it took roughly 30 more seconds for their resting breathing rate to return.
Reflection
During this project, I got the privilege to work with some of my closest friends. I found that this actually helped my understanding of the knowledge we were trying to gain. I found that my energy and my mood were a lot higher during this project, because I was comfortable and knew the working style of the people I was with. If I had to criticize something however, I'd say that we could have planned everything out more thouroughly and I could have done better time management. However, I think that I collaborated well with my teammates and stayed mostly on task.
