STEM-to-public science communication is recognized as an important skill, but a pedagogical framework for teaching these skills is lacking. Collaborating with safety and science communication experts, an educational innovation was developed in a health and safety course for chemical engineering students. Students attended three science communication workshops and conducted a mock town hall based on briefs from historical chemical incidents. Initial and follow-up surveys show that students’ self-efficacy around these skills improved following participation in the educational innovation.
