Shivering Isn't Enough: Heat Conservation In Homeotherms
Questions
1) For each animal tested, describe the relationship between temperature
and time. In each experiment, which animals tend to lose heat
most easily? Base your answers on the slopes which you determined.
2) How does the layer of insulation affect heat loss in your animals?
How does the shape of the animal affect heat loss in your animals?
Do your results support or refute your hypotheses? Explain.
3) Consider the four animals drawn below. One rabbit and one fox
lives in a cold weather climate where it must conserve heat. One
rabbit and one fox lives in a warm weather climate. Based on your
results, match the four animals to their climates. Be sure to
explain the basis of your choices.
A. show picture of desert jack rabbit.
B. show picture of snow shoe hare.
C. show picture of arctic fox.
D. show picture of desert fox.
4) Describe some ways in which homeotherms conserve heat which
are not covered in this lab.
5) Describe some ways in which homeotherms lose excess heat which
are not covered in this lab.
6) What are the differences between homeothermic and poikliothermic
animals.
