To teach the most central concepts in evolutionary biology, we present an activity in pollination biology. Students play the role of either pollinator or flower and work through a set of scenarios to maximize plant fitness. This “Pollination Game” facilitates critical and inquiry-based thinking, and we accompany each round of the exercise with a set of discussion questions and answers. We have piloted and fine tuned this exercise with high school students, and improved the exercise with the input of high school teachers at a teaching conference. The activity could easily be adapted for freshman undergraduate students.
