Complex systems are challenging for students, especially younger students, to learn. In this paper, we argue that agent-based models (ABMs) of social insects provide an engaging and effective space for students to learn powerful ideas about complex systems. We designed a curricular unit called BeeSmart centering on ABMs of honeybees collective behavior. Preliminary results from an implementation at a high school showed that ABMs of social insects could be a promising approach to introduce complex systems to a younger audience.
