Overview: In this investigation, we were asked to explain ways homeostasis could be represented and restored. My group chose the effect of external temperature on internal temperature (thermoregulation). Throughout the project, we learned that homeostasis is the balance that your body tries to keep and that your body temperature can fluctuate a lot.
Steps:
Take the temperature of the person at room temperature.
Have the person stand outside for 5 minutes.
Take the temperature of the person when the time reaches 2 and 5 minutes.
Record the data.
Check if the data seems right.
Look at the similarities and differences between the trials.
Repeat
With all of these steps complete, we were finally done with our experiment and we just had to put all of our research into a rough draft poster. We then had to finalize our information into a poster to hang in the hall way.

Content:
Independent Variable: The Independent variable causes the difference of the dependent variable in our project. It is what you change in your project. Link to work: Our independent variable was the difference in external temperature. Link to other subjects: The independent variable is used to reason why results come out as they do in science and it is used throughout science. It is usually used in mathematical and statistical modeling.
Dependent Variable: The dependent variable is the result of the project and is mainly influenced by the independent variable. Link to work: Our dependent variable was the internal temperature that kept changing. Link to other subjects: The dependent variable are the results of the experiment that happened and we use these results to figure out why something happens. It is usually used in mathematical and statistical modeling.
Control: The control variable is an experimental element that doesn't change. Link to work: Our control variable was the room temperature which never changed. Link to other subjects: This is used throughout science to differentiate normal vs effected variables.
Positive/Negative Feedback: Positive feedback occurs to increase the change or output: the result of a reaction is amplified to make it occur more quickly. Negative feedback occurs to reduce the change or output: the result of a reaction is reduced to bring the system back to a stable state. When the body temperature rises, a number of physiological responses are triggered in order to cool the body down. The physiological responses are sweating or any way of getting water out of your body. Conversely, when the body temperature falls, responses are triggered to warm the body up. The physiological responses would be shivering to move the muscles to warm up the body. Link to work: In thermoregulation, the body uses feedback loops to maintain a good body temperature. When the body temperature falls, responses are triggered to warm the body up. The physiological responses would be shivering to move the muscles to warm up the body. Link to other subjects: The positive/negative feedback loop is used throughout science and an example would be the brain sending signals to the body when something is too hot or cold and that's what our project was all about. It can be used in many different ways.
Homeostasis: Homeostasis is the balance of the body's temperature, heart rate or blood pressure. It maintains the balance that the body needs in order to survive and be healthy. Link to work: This relates to our project because it was all about maintaining the body temperature. Link to other subjects: Homeostasis can be used in many different ways like breathing rate, heart rate, PH levels, etc. It will let you stay healthy and have a balanced body cycle.
Scientific Method: The Scientific Method is a process used in experimentation and it is used to make theories about a scientific experiment. Link to work: We used the Scientific Method in our project to create our poster. Using the method, we were able to make a sophisticated poster with a hypothesis, data, analysis, and conclusion. Link to other subjects: The scientific method is used throughout the world in many different fields of science. It is how our body stays healthy.
Stimulus: The Stimulus is something that causes an expected reaction to happen. It creates a response for the body to have. Link to work: In our project, the stimulus is the weather outside which then turns on the response. Link to other subjects: The stimulus is used throughout science to reason why things happen as they do. It is to aid in homeostasis so that the body is healthy.
Response: The response is the output of the stimulus. It counters the stimulus and makes the Link to work: Our experiment showed that the response was shivering. Link to other subjects: The stimulus is used throughout science to reason why things happen as they do. The response is very important because it is what the stimulus provides after doing the experiment.
Reflection:
Two of the skills that I did well on in the project were critical thinking and communication. I did well with critical thinking because when the data that our group collected seemed a little off I said something and we took the data again with a different thermometer. I did well with communication because I was able to talk to all of my group mates and we were able to talk to each other.
Two things that I can work on for next project are conscientious learning and collaboration. I can work on conscientious learning by taking in what my group mates say and learning from it. I can work on collaboration by being there more days for the project and working harder on it.
In conclusion, I think that my team and I had a great project that proved that homeostasis works all day and every day to keep our body running and us feeling good. We learned a lot of stuff about how your body's temperature works and everything to go along with that. This project helped us gain a lot of knowledge of homeostasis that we would not have known about if we did not do this project.
