Biology students require broad preparation for diverse careers including agriculture, natural resource management, and laboratory research. Concurrent with this need, employers are seeking applicants who have the scientific skills that allow them to solve problems related to locally relevant economic systems and develop ways to foster economic growth. To support these efforts, biology faculty from six different campuses in the University of Maine System collaborated to develop an economically relevant activity where students differentiate the roles light energy, carbon dioxide, and nutrients have in photosynthetic organisms. In addition, the activity addresses the relationship between photosynthesis and global carbon dioxide cycles, as well as the potential impacts of rising global atmospheric carbon dioxide on economic industries that rely on these processes. The activity was taught in 11 classrooms throughout the University of Maine System, and student performance was assessed using a multiple-choice pre/post-test, pre/post constructed response questions, in-class clicker questions with peer discussion, and exam questions. Here we report that the activity improved student learning and that combining the expertise of University of Maine System faculty and the Hurricane Island Center for Science and Leadership provided the opportunity to integrate biological concepts with economic development. Although the examples in this lesson have economic relevance in the state of Maine, the examples can be modified to align with other regional economic systems.
