The Bergmann rule: heat loss as a function of the body sur face area and volume (with the Cobra3 Basic-Unit)

 Product No: P4100211

Principle

Demonstration of different heat losses in dependence on body surface area and volume.

Tasks

  1. To prepare a graph which demonstrates the different heat losses with different volumes and body surface areas.
  2. To interpret data on the settling of warm and cold regions by lager or smaller animals.

What you can learn about

  • Bergman rule
  • Heat losses
  • Lager versus smaller animals
  • Coler versus warmer regions of the world
