Homeostasis
Project Description: Homeostasis is the body's maintinance of balance in the body. In this project, we designed and carried out an experiment to test on form of homeostasis. We chose thermoregulation, the body's regulation of internal body temperature to keep it at around 96.8°F.
We tested thermoregulation by following the body temperatures and symptoms of three subjects through warm and cold conditions. They were all wearing shoes, jeans, and a short-sleeved shirt. We began by measuring their baseline body temperature, then asked them to put on a hooded sweatshirt, scarf, down jacket, and warm hat. We measured their body temperature every minute for 15 minutes. We also periodically asked them to describe how they felt, whether they were sweaty, and if they had dialated veins. After they took off the layers, we waited 5 minutes for them to cool off and went outside, where it was about 60°F. We recorded their body temperature every 15 minutes and periodically asked whether they had shivers, dialated veins, or goosebumps.
Then, we drew results from our findings. We concluded that we did indeed see homeostasis in action. The subjects' bodies stayed within 0.5-2.3°F of their original temperature. See our Prezi and google doc below for more justification and details.
