A model illustrates how removing one species affects the remaining populations.
The rabbit and hawk populations without foxes present.

The goal of this activity is to give students the
opportunity to “think like a scientist,” making hypotheses, doing experiments, making
observations, and analyzing data. Students are encouraged to construct and
conduct their own experiments with ecosystems comprising grass, rabbits, and up
to two predator species: hawks and foxes. (Evolution Readiness Activity 10 of
