Reflection
This project was a lot more hands on than some of the other ones we have done this year. I really enjoyed it and hope we do more in the future. A huge bonus was that we could chose our groups and I worked with my friends. This improved all our attitudes towards the project and made it a lot more enjoyable. We all collaberated really well and it helped when it came time to gather data and analyze it. Another thing we did well was adapting to the circumstances. A few times, we had to tweak our experiment due to lack of proper equipment and certain conditions. We worked together and communicated to solve the issues that presented themselves. One thing I could improve on is staying focused on the important parts of the project. Many times I would find myself working on our project, but focusing too much attention on the minor details. Another thing we can improve on is time management. Usually, we are very good about this, but for this project we found ourselves in a little bit of a time crunch. In the end, our poster turned out great, and we were very satisfied with the content of our final work.

Our Project
For the third project, we looked into homeostasis. We studied the various ways our body maintains itself in different environments and what triggers these reactions. After choosing a specific area in the body to focus on, we conducted some field tests looking at the different variables in this process. After conducting these tests, we analyzed the data and created a poster to show our conclusions.
After learning some more background knowledge, my group (Brigid, Tara, and Ashley) and I chose a body function to observe. We chose the lungs and the respiratory system. To test homeostasis, we designed a running experiment. This included having 2 physically fit boys and girls run certain distances around the track. We measured each participant's resting breathing rate as well as after each test was completed. Participant 1 plays basketball and is fairly physically fit, participant 2 plays baseball and is physically fit, participant 3 runs cross country and is physically fit, and participant 4 plays soccer and is physically fit. After our volunteers ran, we analyzed the data and using this information, we created a poster to present to the class.

Results
The results we found after running the experiment were that no matter the gender, everyone takes longer to get back to resting breathing rate after a certain amount of physical exertion. Every time more distance was added to the run, it would take the runner about 30 more seconds to get back to resting breathing rate. Participant 1 had a resting breathing rate of 24 breaths per minute and took 1 minute to get back to resting breathing rate after running the 100m, 2.2 mins after 200m and 3 mins after 400m. Participant 2 had a resting breathing rate of 35 and took 1 minute after 100m, 2 minutes after 200m and 2.5 minutes after 400 m. Participant 3 had a resting breathing rate of 20, and participant 4 had a resting breathing rate of 21.They both took 1.5 minutes after running the 100m, 2 after 200m, and 2.5 after 400m to return to that normal rate of breaths per minute.

Content
We used all these terms and concepts within our project. The respiratory system includes the lungs and gas exchange (oxygen, CO2, nutrients, etc.). We used our knowledge of this in our experiments and analysis.
Homeostasis- how the body maintains itself through various interdepentent cycles
Respiratory System- the set of organs that allows a person to breathe and exchange oxygen and carbon dioxide throughout the body
Resting Breathing Rate- the number of times a person inhales within a minute
Gas Exchange- The primary function of the lungs; transfer of oxygen from inhaled air into the blood and the transfer of carbon dioxide from the blood into the exhaled air
Lungs- responsible for getting oxygen into the body, and exhaling "toxins"
Oxygen- a gas in the air that we need to survive
Carbon Dioxide- waste product of our bodies
