INtroduction
In this project we were assigned to investigate a type of homeostasis and how it works, what affects it, and how it is maintained. My group, with Nico Lofrano, and Kiki Brabo, chose to do ours on blood pressure. We knew that sodium caused your blood pressure to increase so we decided to test the effect of high sodium intake on the homeostasis of blood pressure. So we decided to use instant ramen, since it has a 50% daily value of sodium, and see if it affects our blood pressure. We made a research paper and scientific poster as a result from our research.
Concepts
Homeostasis - The body's process of maintaining stability and consistency. It is necessary for the body to function properly. It functions through feedback loops to correct changes.
Feedback Loop - A biological system used to maintain homeostasis. A stimuli causes the body to send a message, that message then triggers a response to the stimuli. Either positive or negative based on the stimulus and response. All homeostasis feedback loops are negative.
Blood Pressure - The pressure at which blood is as it travels through the circulatory system.
Systolic Pressure - The pressure of the arteries when the muscles contract and blood pumps from the chambers in the heart into the arteries.
Diastolic Pressure - The pressure of the arteries when the muscles relax and blood pumps into the chambers in the heart.
Arteries - The tubes in the circulatory system that carry blood away from the heart. Blood pressure is the measurement of pressure in the arteries.
Scientific Method - The way scientists conduct an experiment, the steps are: Question, Hypothesis, Prediction, Test, Results, Conclusion.
Independent Variable - A variable that is not dependent on another variable.
Dependent Variable - A variable that is dependent on another variable.
Constant - An unchanging part of the experiment.

Conclusion
This project did not go the best, but was not the worst. One main problem we had was our efficiency. We were behind for almost all of the project, we kept getting delayed, and we had very little coordination. Another issue we were faced with was distractions. All of us were constantly distracted by others, I had to constantly remind my group-mates to stop talking to Daniel B and get on task, and Mathews and to remind me to stop talking to Daniel F and get on task.
The positives of this project were, for one, was our ability to get the work done even with the distractions, I did most of the poster at home sick on the weekend, and Kiki got a lot of the article done while in Las Vegas. Even though we struggled with distractions in class we eventually pulled through and finished everything. Another positive of this project was our groups cohesion, while we didn't work the best together, there wasn't and fighting and all decisions were agreed upon unanimously. All in all this wasn't the best project, but it also wasn't the worst.
