Virtual laboratory activities are flexible approaches to engage undergraduate students in scientific practices during the COVID-19 pandemic. By utilizing online simulations, students can conduct virtual experiments on important biochemical reactions that occur during photosynthesis. The learning module described here provides students with this experience and was implemented for first-year students in a virtual summer bridge program. It introduces new biochemistry majors and nonmajors to the discipline, and it is based on an in-person photosynthesis laboratory module taught for the summer bridge program before the emergence of COVID-19. This virtual laboratory module can be readily adapted for use during the academic year in introductory biochemistry courses.
