| Abstract | To most students entering today's biology classes, evolution is something that occurred long ago, and is therefore irrelevant to their lives. Examples of evolution that are important concerns in the modern world, such as the resistance of insects to pesticides and antibiotic resistance, do not match students' concept of evolution. In this article, the authors present and describe the "Jelly bellicus" activity, which is an effective tool in teaching students the basic principles of natural selection and the concept of evolution as significant to their lives. The activity uses students and jelly beans to simulate the selection forces placed on populations by predators. To adapt the activity to the high school science classroom, the authors created a fictional narrative and characters that demonstrate the effects of cryptic coloration and mimicry. In the activity, students play the role of competitive predators by collecting jelly beans in an effort to "survive"; as students progress through the activity, they learn that some jelly beans thrive while others become endangered or extinct.
