The SuSTEMable Agriculture professional development workshop introduced thirty-eight science teachers to concepts and activities related to sustainable agriculture that could be incorporated into their middle or high school classes. The program included presentations and demonstrations by agricultural researchers, practice with related class or lab activities, and discussions of college majors and career options in agriculture. Teachers were provided with supplies to use in their classrooms as they integrate agricultural issues and challenges in their biology, environmental science, chemistry, or other STEM courses and introduce students to related career opportunities. Pre- and post- assessments were used to assess teacher comfort in teaching different topics and to measure their content knowledge. Results indicated a significant positive difference in confidence in their abilities to teach about select topics in sustainable agriculture before and after the workshop, as well as in their subject knowledge in most of the topics covered.
