Homeostasis- state of steady internal conditions maintained by living things within the body. This equilibrium is required in all of the body's systems, which require certain amounts of water, heat, and nutrients.
Overview
For this project, we were given minimal instruction. The purpose was to observe the process of homeostasis in a given area. The one we tested was blood pressure. Therefore, we were to see how the body's blood pressure changed in response to an outside factor, then return to its original level.
Having done so, we were then to create a research article and poster that were presented to the class. The results are below.
Concepts
Epinephrine-hormone secreted to increase the BPM in the heart Catecholamines-hormone secreted to decrease the BPM in the heart Independent Variable-a variable which does not rely on another(Time) Dependent Variable-a variable relying on another variable(BPM) Control Variable-a variable or test used as a baseline for future results(Resting BPM) Scientific method-A scientific procedure used in the pursuit of conducting an experiment: Observe, Question, Hypothesis, Develop experiment, Test experiment, conclusion, communicate Beats per minute(BPM)-amount of heart beats in a minute Feedback loop-biological occurrence wherein the output of a system amplifies the system or inhibits the system

Reflection
Over the course of this project, there were several things that were done well, and somethings that could have been done better. In the former category, there are many things to be placed. As a group, the fact that we had all worked together before meant that we more cohesive as a team. This lead to a better brainstorming process, resulting in more imaginative ways to achieve our goals. Also, this lead to more communication of ideas regarding individual working areas. This resulted in a higher quality end product. The result of us working together also involved some issues. As with all projects, there were some members that were off task. This was exacerbated by the friendly atmosphere, and resulted in a somewhat unproductive environment. The second issue with this assignment was more administrative. The instructions, while intentioned to be brief, were the cause for much confusion in the class/group. It was unclear what the goal was of the project, and had to be clarified in greater detail.
