Mississippi Science ZOO.9.3
The Standard
- ZOO.9
- Students will understand the structure and function of phylum Chordata, class Aves, and how they demonstrate the characteristics of living things.
Define the term endothermic and describe how birds regulate body temperature in extreme environments.

What This Standard Means
What Students Need to Do
- Students explain that endothermic animals produce body heat through metabolism. They describe how birds keep heat in during cold weather and release it during hot weather.
What Mastery Looks Like
- A student explains that shivering produces heat, fluffed feathers slow heat loss, and panting cools through evaporation. They can choose a fitting response for a bird in extreme cold or heat and explain why it works.
Common Misconceptions
- Students may think endothermic means a bird's temperature never changes. They may think feathers produce heat or that birds sweat like humans to cool down.
How to Assess It
- Ask students to define endothermic, then explain how a bird could stay warm at −10°C and cool down at 40°C. Have them name one response for each temperature and explain how it works.

Ways to Teach It
Wrap one jar of warm water in a down jacket sleeve and leave a second jar bare; measure both temperatures after ten minutes.
Ask students to write why a bird might fluff its feathers on a cold day but pant on a hot one.
Give pairs cards labeled shiver, fluff feathers, pant, and seek shade; have them sort the cards by cold or heat and explain each choice.
Read a local heat advisory, then ask students why birds might seek shade and pant instead of sweating.
