This session will describe the co-development of a freely available online course called The Science of COVID-19 for secondary teachers to use with their students. It provides the perspectives of three interconnected fields of study (virology, epidemiology, and public health preparedness) and guides students through a series of activities similar to the ways scientists have been learning about both the virus and the disease over the past several months. Most school science courses teach content that has been well-understood for years. Participants will get the opportunity to conduct three of the activities within the course and will participate in small group discussions about several of the relevant topics related to teaching science that is not yet in textbooks. The course is well-aligned with Next Generation Science Standards because it engages the user in science practices as it teaches disciplinary content.
