Description:
When conducting an investigation, the first step is to conduct research about the subject. My crew and I investigated homeostasis by measuring a person's respiratory rate while exercising. However, before we could do the experiment, we needed to learn some background information and answer a few questions. What is homeostasis, how does your particular method of homeostasis operate, and so on were the questions we wanted to address. What organs are affected, what hormones are released, and how does your body react?
We then had to fill out the graphic organizer after we finished answering a handful of questions regarding our topic. What we were testing, the protocol, the hypothesis, the independent and dependent variables, constants, control variables, and the experimental run were all components of the graphic organizer that we had to fill out as a group. This has to be done before to the actual experiment so that you know exactly what you're doing and what kind of data you should be gathering.
We went to the track to conduct the procedure after filling out the graphic organizer. Our approach involves two participants jogging two laps around the track to determine if their respiratory rate increased after each lap and then returned to normal after three minutes of rest. We all gathered data and jotted down our observations. After the experiment, it was time to turn our findings into a presentation. A graph, data table, clear paragraph, introduction, technique (materials and methods), discussion, and finally a work's cited page made up the presentation. After all our research and work has been done we had to present to the class about our findings during this respiratory project.

Dependent Variable- The thing you change or are manipulating. Our dependent variable was the breathing rate (breaths per 15 seconds). An example of a dependent variable in another experiment like the product Feliway would be the cats. The dependent variable was important for the completion of the project because it's what our homeostasis was based off of.
Independent Variable- It is the thing you are measuring or responding to. Our independent variable was the total distance ran. An example of an independent variable in another experiment like Feliway would be the cats behavior.
Control Run- The baseline that you compare everything to. Resting breathing rate before run. Or for example it could be people who don't use crest whitening strips compared to the people who do.
Experimental Run- The trials where you changed things. Our's was the change in breathing rate. During every trial your breathing rate would change as you increased the distance you ran.
Constants- All the things that are the same between each trial. Time of measuring breathing rate (15 seconds each time). Kept the time we measured the breathing rate the same so you could compare accurately between the trials.
Procedure- What you are going to do for the experiment. A list of the things you are going to conduct in order.
Go to San Marin track
Have someone run half a mile
Check breathing rate before the run
After Every lap, have the runner stop to check their breathing rate
Check breathing rate by counting breaths for 15 seconds to get breathing rate per 15 seconds
After both laps have been completed wait another 3 minutes to see if it went back to a stable breathing rate.
Then repeat for next trial
Sample size- How many people or animals are going to be used during the experiment? During the experiment, two people ran and out of those two people one person ran twice. Normally sample sizes for experiments are large and contain lots of people or animals or objects.
Hypothesis- Can be an if then statement. If someone run's half a mile on a track, then every-lap the person complete's there breathing rate will increase. Always create a hypothesis before you conduct an experiment because this is what you will be testing off of for the experiment. At the end of the experiment you will write a clear paragraph to determine if you proved your hypothesis to be true of false.
Homeostasis- Systems in your body monitor and regulate important parameters of the body and keep them within normal levels(equilibrium). The respiratory system maintains homeostasis by using gas exchange and regulation of blood ph. Gas exchange is when the lungs eliminate carbon dioxide. Progesterone, Thyroxine, Corticotropin, and Leptin are used within your body to stimulate your respiratory system to breathe and take in the oxygen in the atmosphere. Also, the faster that you are breathing the more of these hormones are released to help regulate breathing.
Pros :
I think our Character was good in this project sine we had to step up to run for some other people who couldn't because they were injured
Our Critical thinking also was great since we had to oversee the statistical aspect in a harder way due to formatting sheets but we overcame it
Cons:
Our communication was bad due to us having to change roles for different tasks then we are usually used to
Although our Collaboration was bad because different people had to redirect new roles and had to make the work equal
