This project will provide K-12 teacher professional development and focused student activities to promote environmental literacy using the essential principles of ocean and climate literacy. In partnerships with NOAA entities, school districts, and museums across the United States, we will provide: (1) high-energy face-to-face professional development workshops for teachers, facilitated by experienced educators; (2) ongoing support and interactions among teachers and students through an online collaborative website, or group-hub; and, (3) high-profile, focused events in which students interact with scientists and the public to share what they've learned, both locally and internationally. The primary goal of this project is to increase the environmental literacy of K-12 teachers and their students from school districts that are part of existing science museum networks. Each summer, we will work with 4 to 6 partner museums to invite 30 to 40 teachers from their local school districts to take part in a pair of workshops.
