Description

In this inquiry-based activity, students engage in science practices to figure out ways environmental factors drive the natural selection and adaptation of Galápagos finches.

This activity is based on content covered in the short film The Origin of Species: The Beak of the Finch. Instead of front-loading information from the film, the activity guides students through “figuring out” the key concepts first. Students make observations, analyze data, search for patterns and cause-and-effect relationships, construct arguments, and make predictions about the evolution of finch populations.

The “Card Images” ZIP file contains individual image files for the cards used in this activity that can be used in the classroom, particularly in online courses.

Student Learning Targets

  • Use evidence from observations to make claims and construct arguments about the evolution of Galápagos finches.
  • Use data to make predictions about the evolutionary relationships among finch species.
  • Obtain, evaluate, and communicate information regarding how evidence can change thinking about scientific phenomena.

Estimated Time

Two 50-minute periods, possibly more if doing the extension.

Key Terms
