This article describes an inquiry-based activity that takes the process
several steps further. In this inquiry-based activity, students not only examine adaptations that birds have for
capturing prey, and changes in a bird population over time, but also hypothesize what would happen to the bird
population if relative seed abundances change over time. Students then model an environmental change recorded by
researchers when observing Darwin’s Finches. The Grant’s observed a severe drought in 1977 resulting in a drastic
decline in seed production with small seeds being particularly affected (Grant, 1999; Boag & Grant 1981). Students
then test their hypothesis and compare their findings to those observed by the Grants. This activity is well suited for
students in general biology, ecology or evolution classes.
