Homeostasis Lab

For our homeostasis experiment we followed a number of steps. We measured Jill's elbows temperature while she was resting in class and it comfortably leveled out around 87 degrees. Then we measured her elbows temperature after she had been lifting weights for over 20 minutes. Her temperature continued to climb until it leveled out around 98 degrees. After sitting and cooling off for quite some time Jill's temperature finally lowered back down to 87 degrees. This is an example of negative feedback because her body was able to cool back down after getting so hot. In the end Jill's temperature finally reached homeostasis.
