Biology: Too Hot? Too Cold? Just Right!

by Texas Instruments - Simulation Lesson


  • Students will simulate environmental temperature changes and observe the effect of temperature change on the metabolic rates of two different animals.
  • Students will develop an understanding of the effect of environmental temperatures on endotherms and ectotherms.
  • Students will develop an understanding of the relationship between environmental temperature and animal metabolism.


  • circadian rhythms
  • ectotherm
  • endotherm
  • hibernate
  • homeostasis
  • insulation

About the Lesson

This lesson involves students using TI-Nspire technology simulate the effect of environmental temperature on the metabolisms of both endothermic and ectothermic animals.
As a result, students will:

  • Differentiate between endothermic and ectothermic animals.
  • Develop an understanding of the physiological needs of endothermic and ectothermic animals.
