In this project me and my team were given the chance to choose a certain Homeostasis to research and write a report on. We all decided on Blood pressure as our homeostasis. To begin the project we had to choose what type of exercise we wanted to test with. We choose to do 20 jumping jacks. Before the exercise we would record our blood pressure and then after the exercise we recorded the blood pressure and come to the conclusion our hypothesis at the beginning was true.
Homeostasis - The tendency toward a relatively stable equilibrium between interdependent elements, especially as maintained by physiological processes (noun) (oxfordlanguages.com)
Adrenaline - A hormone secreted by the adrenal glad's, especially in conditions of stress, increasing rates of blood circulation, breathing, and carbohydrate metabolism and preparing muscles for exertion (noun) (oxfordlanguages.com)
Blood Pressure - The pressure of the blood in circulatory system, often measured for diagnosis since it is closely related to the force and rate of the heartbeat and the diameter and elasticity of the arterial walls (noun) (oxfordlanguages.com)
Feedback Mechanisms - The regulation system of the human body that allows the body to return back to its normal internal state
Positive Feedback - Feedback that makes a process greater, increases its output
Negative Feedback - Feedback that causes a system a counter response to return back to a set point
Feedback Loops - The process where the outputs of a system are circled back and used as inputs
Control - The element that remains unchanged or unaffected by other variables (ex. resting blood pressure)
Independent variable - The variable that stands alone and remains unchanged by other variables (ex scary movie)
Dependent variable - The variable that changes as a result of the independent variable (ex. blood pressure/adrenaline)
Constant - The factors that remain unchanged (ex people/blood pressure monitor)
Scientific Method:
1. Problem/Question - The problem is a question you form based on your observations that you can test with an experiment.
2. Observe/Research - Observe around you if you need to for your experiment and then do research about
3. Hypothesis/Prediction - Predict a solution or reasoning to the problem based on your research
4. Experiment - test your hypo step by step. Make sure it is explained well and has lots of detail. Also label all materials used and have an independent and dependent variable.
5. Collect Data - Collect information and observations you saw during the experiment. Be very descripti
6. Analyze Results - Display the data using graphs and tables.
7. Conclusion - The solution to the problem. Explain is your hypothesis was correct or incorrect. Summarize your results
8. Report Findings - Report and share all your information to others
During this project there were some up and downs such as when the blood pressure tester would squeeze our arms to the point where it hurt but some good that came put of it was that everyone laughed which made collaboration easier when you feel like your in a safe environment. Two things i learned during this was to have fun and to be kind and supportive with each other.
Two things i could work on is definitely the same thing as always with my ability to stay focused during the whole project. Another would be my attitude towards the teacher. I got to keep my cool and realize she is also trying to help her.
