Cold-blooded and Warm-blooded Animals
Exploring Meanings and Implications

The fact that monarch butterflies are cold-blooded affects every aspect of their lives. A monarch's ability to move, the rate at which it develops from egg to adult, its ability to survive the winter in Mexico without food—are all ways the temperature of a monarch's environment regulates its life.

Children studying monarch butterflies will have questions related to body temperature, thermoregulation and metabolism. Use these resources and activities to explore and build understanding. Discussion Questions are provided to support learning.

Teaching Suggestions
These Discussion Questions are provided to support learning. Student directions are provided on the blank Facts Sheet and Comparison Chart. Students can collect facts from their own research or while reading these related slideshows: Temperature and Survival, No Food for Five Months?, Too Cold to Fly? Both Journal Pages give students an opportunity to work with the concepts.
