In this lab we were testing a form of homeostasis that could be found in the human body. We were seeing how long it would take for our body to get back to a normal state. We decided to see how temperature effects your blood pressure.
Content
Homeostasis:
The tendency toward a relatively stable equilibrium between interdependent elements, especially as maintained by physiological processes.
Blood Pressure:
It is the amount of force the blood being pumped has on the arterial walls.
Systolic:
It is the top number when you look at blood pressure. It represents the amount of pressure in your arteries during the contraction of your heart muscle.
Diastolic:
It is the bottom number of the blood pressure reading. It shows the amount of pressure in the arteries in between the heart’s beats. This is when the heart fills with blood to get oxygen.
Osmosis:
The movement of water from a high concentration to a low concentration.
Hyper-tonic:
Too much water moving out of the cell leaving the inside dehydrated.
Isotonic:
Equal amount of water moving in and out of the cell.
Hypo-tonic:
Too much water coming into the cell.
Solute:
What is being dissolved.
Solvent:
What solute is being dissolved into.

Abstract
Objective:
The objective of this study was to test how the surrounding climate effects your blood pressure and to prove homeostasis in blood pressure.
Design:
Four teenage high school students were put into a group to conduct a lab to study homeostasis.
Subjects:
We tested our procedure using two, 15 year old, boys
Analysis:
The closer the water is to room temperature the closer the blood pressure is to normal.
Variables Measured:
Blood pressure before and after submerging their hands in various temperatures of water.
Results:
We found that if the water was colder, it increased the subject’s blood pressure. Also, we noticed that it took our subjects about 3 to 5 minutes for their blood pressure to return to normal.

Introduction
Blood pressure affects the heart and the kidneys. Depending on the cause, different hormones are in effect, but some of them are aldosterone, epinephrine (adrenaline), and rennin. Blood pressure can be increased by a number of things whether it be genetics, stress, age, or eating habits. However, some people do not know that activities you do before you get your blood pressure taken can affect the results. For example, caffeine intake, medications, physical activity, and what we’re observing, temperature. Over time, high blood pressure can affect your brain, kidneys, and eyesight in a negative way. They can deteriorate because the high amount of pressure can harm your arteries, which could slow blood flow. A slow blood flow limits the amount of blood tissues and organs get, sometimes damaging the brain, kidney, and eye.
We are performing a lab to see how different temperatures affect your blood pressure. We hypothesized that the warmer the water temperature, then the higher your blood pressure.

Method
Materials
1. Blood pressure cuff
2. Bowl
3. Hotplate
4. Thermometer
5. Ice cube
6. Bowls of 30℉, 50℉, 70℉, 90℉, 110℉
7. Salt
Procedure
1. Take your resting blood pressure as a control for each test.
2. Prepare 5 bowls that each have 4 cups of water, or enough to fully submerge your hand in the water.
3. Put ice a bowl until the bowl of water gets to 30 ℉ (add salt if the water isn't reaching that temperature with ice alone)
4. Place your hand in 30℉ water. for 2 minutes, then take out of the water.
5. Take blood pressure and record it.
6. Repeat for 50℉, 70℉, 90℉, 110℉ water.
7. Graph the change overtime.

Results
SYS=systolic, this is the top number when you look at blood pressure. It represents the amount of pressure in your arteries during the contraction of your heart muscle.
DIA= diastolic bottom number of the blood pressure reading. It shows the amount of pressure in the arteries in between the heart’s beats. This is when the heart fills with blood to get oxygen.

Observations
We observed that it was a challenge to work with the blood pressure cuff since none of used had used one before. We also noticed that it was more uncomfortable to keep your hand in the colder water, and the warmer water was comfortable.
Discussion
Our data shows the resting systolic and diastolic versus the systolic and diastolic of our subjects after putting their hands in different temperatures of water for 2 minutes at a time. The data shows that the closer the water was to room temperature the closer the blood pressure was to normal. You can see that with the 30℉ water, the resulting blood pressure was very different than the original because it was the farthest from room temperature.
One thing that went very well in this experiment was the choosing of the water temperatures. We were able to get a variety of different temperatures without harming our subjects.
One error that happened in our lab was not fully understanding how to use the blood pressure machine. Since we did not know how to correctly use it, the first few blood pressure readings were completely inaccurate. Another error we had was not running the same test on every subject or having each subject do every test.
Next time we can improve the lab by testing each temperature more than once so we can get an accurate array of the data. We can also take the subjects blood pressure after a certain interval to get a better idea of homeostasis.
One question that has stemmed from this lab is what other functions that have homeostasis in our body are affected by temperature.

Reflection
Some peaks in this project was that I was able to lead my group, made sure we were on task, and I learned a lot of valuable information from this project like how to take blood pressure. I was able to lead my group by making sure that everyone had an equal part in the project.
Some pits of this project was that I needed to make sure that everyone in my group had a task the could accomplish because one group member was not always there so we could not give them a big part. We also could have communicated better so I would not have to the poster all by myself. Even though we were productive we could have worked better with each other because most of the time we work independently and we did not work as a group.
