Background info: To survive, an organism must be able to maintain stable internal conditions in a changing environment. This process is called homeostasis. The Human Homeostasis Gizmo allows you to explore how the human body stays at a nearly constant temperature in different conditions. Notice the Air temp. and Body temp. thermometers representing the air temperature and body temperature. Initial Air Temperature:
