Unit

Balancing Act: Tradeoffs in frogs, humans, and other animals

Grades

9, 10, 11, 12

Balancing Act unit banner

Students will follow in the soggy footsteps of scientists wading through ponds at night to record frogs as they learn about biological tradeoffs that connect humans to horses to frogs. Along the way, they'll decide which male a female frog should choose as a mate, based on analysis of call performance.

Alignment summary( Target)

Lesson 7

The culminating discussion in Lesson 2, where students connect their findings on trade-offs to broader biological concepts, ties into explaining how natural selection drives adaptation in populations, particularly how performance thresholds can determine fitness and reproductive success in a given environment.
