In the homeostasis lab we are using as a homeostatic parameter.

Body temperature

Explanation:

We use body temperature as homeostasis parameter in the lab.

Homeostasis can be described as a self regulating mechanism used by the body systems for stability maintainable so as to adjust to several conditions that are important for survival.

The way the body controls the body temperature in humans is a good description of homeostasis

the abdomen (less formally called the belly, stomach, tummy or midriff) constitutes the part of the body between the thorax (chest) and pelvis, in humans and in other vertebrates. the region occupied by the abdomen is termed the abdominal cavity. the stomach secretes acid and enzymes that digest food. ridges of muscle tissue called rugae line the stomach. the stomach muscles contract periodically, churning food to enhance digestion. the pyloric sphincter is a muscular valve that opens to allow food to pass from the stomach to the small intestine.

the principles and empirical processes of discovery and demonstration considered characteristic of or necessary for scientific investigation, generally involving the observation of phenomena, the formulation of a hypothesis concerning the phenomena, experimentation to test the hypothesis, and development of a conclusion that confirms, rejects, or modifies the hypothesis.
