Evidence of Work:
In this project my group and I were tasked with choosing a way that the human body maintains homeostasis. My group consisted of Pranav, Luke, and Ethan. My group decided on heart rate and chose to see how it raises and why and then returns back to its original state. We followed the scientific method and to show our research, procedure, and results we created an article and then a poster to make it as organized as possible.
Content:
Homeostasis: Homeostasis is the act of the body maintaining stability. In our project this was proved by stressing the heart and increasing the heart rate and then observing how it goes back down.
Hormones (adrenaline, catecholamines): Adrenaline increases the rates of blood circulation, breathing, metabolism, and prepares muscles for exertion. Catecholamines serves as neurotransmitters, sending signals to different parts of the body. These both were triggered when we ran our testing.
Heart: The heart is an organ that pumps blood and circulates nutrients and oxygen throughout the party. In our test we found that the heart rate increased and decreased according to how much blood the body needed to circulated around the body.
Lungs: Lungs take in oxygen when you inhale and releases carbon dioxide when you exhale, allowing you to properly breathe. They were used in our project because lungs are always used ,but especially when the heart rate is increased which it was in our testing.
Independent Variable: It is the outcome of other tests that have been done. In our case it was the heart rate after running of the test subject.
Dependent Variable: The dependent variable is the aspect of the experiment that changes as a result of the independent variable and is therefore, dependent.
Control: The control is something that stays the same and is the constant in the experiment. In our experiment it was the resting heart rate before any running was done.
Scientific Method: The scientific method is an organized way of conducting an experiment. The steps include asking a big question, conducting research, constructing a hypothesis, create a procedure, test the procedure, analyze the data, and then finally communicate the results.
Feedback Loop: Feedback loops are a natural occurrence used to maintain homeostasis by triggering a response either telling the organism that it is good and continue to do it or if it is negative it will not do that again.

Reflection:
I personally enjoyed this project because it allowed me to learn a lot about the body systems and how they maintain homeostasis. My main contribution was taking part in the test/experiment that allowed us to see how the heart rate raises and then goes back to its original state. I also took part in the research portion and focused on subjects such as the body systems involved and how the body reacts. I also worked on a our scientific article used to present our research and focused mainly on the introduction portion.
Even though I thought I did very well there were also some things that I could have improved upon. One of which was utilizing my time as well as I could because I had some free time and didn't use it as well as I could have. Another thing I feel I could have improved upon is being present because I missed one day during the project and although it didn't have an effect on us finishing in a future project, it might.
