Homeostasis

Homeostasis is a process that living things use to maintain stable conditions to survive. It keeps your body healthy by stabilizing important organs such as your lungs, pancreas, kidneys, and skin. For example, the hormone adrenaline in your body is released into your bloodstream as a reaction to the "fight-or-flight" stimulus. The adrenaline makes the blood vessels contract, sending more blood to large muscle groups faster.

For our project, we researched and tested how adrenaline reacts to stress on the body. We took a baseline measurement of our heart rate, blood pressure, and breathing rate. Then our team took turns running around the track, 400 meters, and then testing each measurement in three minute intervals. Our results proved our hypothesis true: If you run 400 meters and constantly measure your heart rate, blood pressure, and breathing rate, then you will see your adrenaline levels increase, before decreasing to their original rates.

Reflection

Me and my team learned that listening to others ideas is imperative to a coherent project, and flawless experiment. I learned to speak up and voice my opinions only at the right time. We struggled to keep our experiments consistent. With three different people, running at three different times, and a simple phone timer, it was difficult to get accurate data.

We succeeded in communicating accurately to each other. We worked quick for the experiment and were efficient in getting the writing assignments done. We all did an equal amount of work, even if we had to do some for homework. We were all dedicated to the project, and were there for each other to complete the work.
