In light of the proven benefits of high-quality afterschool STEM programming for teens, the author worked with colleagues at University of Maryland Extension to institute the Pollinator Ambassador program. The program was launched through a county-based 4-H program at a partner site in a community outside Washington, DC. Following the 4-H Thriving Model and other research-based best practices, the program introduced participants to the vital importance of bees and other pollinators through hands-on activities. Its success in engaging participants and building their awareness of science careers can make it a model for other STEM-based youth development programs.
