A few years ago, the city council of Monza, Italy, barred pet owners from keeping goldfish in curved bowls… saying that it is cruel to keep a fish in a bowl with curved sides because, gazing out, the fish would have a distorted view of reality. But how do we know we have the true, undistorted picture of reality? (Stephen Hawking)

The title of this podcast—The A&P Professor—can be a bit confusing. Is it like “The Ohio State?” Is Kevin “the” A&P professor? Are you “the” A&P professor? Anonymous hackers, maybe? Find out in this segment!

7 | Fishbowl Model of Homeostasis

12.5 minute

fishbowl modelMultiple models of homeostasis may be needed for students to fully understand the important core concept of homeostasis. Kevin uses the typical thermostat model (feedback loop or engineered control system) along with several other models. Here, he describes the fishbowl model of homeostasis.

  • Optional equipment for demonstration/storytelling
  • A physiologist’s view of homeostasis (article in Advances in Physiological Education related to the HAPS workshop I mentioned, this paper proposes a particular way to represent homeostasis in a diagram) my-ap.us/2HSJL5b
  • BONUS: The TAPP APP has a sample handout you can use with your students (app only)
