Overall Project and the Scientific Method
Our objective for this project was to prove homeostasis for the topic we chose. Our topic was breathing rate. In our body, when are body has to exert more energy it needs more oxygen. The hormone progesterone is released which causes the body to start to breathe faster. This hormone is generally released during labor to help women breathe faster which aids childbirth. The following is our lab put into Scientific Method form:
Question: How does breathing rate work in our bodies and how does it relate to homeostasis.
Hypothesis: The more energy is used by our body, the higher our breathing rate goes up.
Experiment: For our test, I acted as the test subject. Kian and Simon, my partners, recorded my breathing rate before running. After I ran two laps around the track they recorded my b.r once again.
Recorded Data/ Analysis: We saw that after I ran my breathing rate increased, supporting our hypothesis and proving homeostasis.
Conclusion: In conclusion, we have found that as the body uses more energy, it needs more oxygen.

Concepts
Homeostasis - When an organism maintains a stable environment. Ours was breathing rate.
Hormones Involved - Our hormone was progesterone, which is a hormone that causes the body to breathe faster. It is used in childbirth and exercise
Organs Involved - Nose, lungs, trachea, and bronchi
IV - The exercise, which was running half a mile.
DV - The breathing rate after running half a mile.
Control - Normal breathing before running half a mile.
Tools and Units - We used a paper bag for me to breathe into so that we could record every time the bag inflates and deflates, which indicates when a breath has been completed.
What's the feedback loop - There are two types of feedback loops, a positive and negative. Positive amplifies changes and negative buffer changes.

Reflection
Overall, the project went nearly perfectly. Our results matched our hypothesis perfectly. The whole testing process was pretty easy to do and took almost no time. All group members worked efficiently which is rare in groups where all members are friends. If we were given more time I feel that our end result would have looked a lot more neat and put together. All things considered though, we still did pretty well.
