Lab 1: homeostasis

I have been sick for most of this lab, But I have been here to be used as a Guinea pig.I was apart of the core temperature experiment at which we exerted our bodies for a period of time and recorded our temperatures and how fast it took our body to return to a state of homeostasis. This however had a very big setback with me. My core temperature is below normal. Always around 19.4 to 20.6 degrees Celsius. So in a last ditch effort, we did physical activities outside to try and get my temperature up. so I can actually be in the lab. If anything else it made me colder with all the heat escaping my body, even with a jacket on.

We returned inside, still hopeful that my body temperature was high somewhat. Imagine our surprise when, our little thermometer read my temperature and it plummeted. It literally began out as my normal temperature and then it went, zip, straight down. All of us in my group (i.e. Nick, Cassy, Seth, Jenna, and zeke (or is his name zack? Sorry i am horrible with names)), unanimously voted that i shouldn't be in the tests anymore. Just a monkey wrench in the data.

As of right now we are currently working on our graphs. I would have added a video but again, my iPad ( which I have dubbed skittles) was not on my persona. I shall link graphs back as soon as they are done.

Graph is in. None of the, data that was taken from me was not used. My core temperature, as stated before, was making the data all screwy. ( if the graph does not show up here is a link).

The graph is depicting the body's designated time to return to a state of homeostasis. Now with the hot water, we can see that Cassidy and Jenna had really short return times. Maybe their body temperatures were already hotter and thus just expelled the extra heat to return to it's original state. Seth and Tim on the other hand took longer to return to normal. Nearly a 6 second difference. The boys' body a sorbed the heat due to them having lower temperatures. (This is not always the same, just a fact).

Now in cold water, The girls had a way longer time then before  to return to a normal state. As did the boys. THis in fact shot down my previous statement. Well my new statement is, since everyone is different then this must account for the differences in the time needed to return to a normal state of homeostasis. different people need different amounts of time to return to normal. AS stated before, i was gonna be used in this lab. SInce i wasn't is this now a sign that i am not in a constant state of homeostasis?
