• Summer Institutes:Multi-day immersive professional development programs for K-12 educators that explore the social, economic, and environmental dimensions of sustainability, and ways of bringing these concepts to life in classrooms through hands-on STEAM activities, case studies, and fieldwork. The Institutes build practical curriculum integration of stewardship perspectives, skills and action to the restoration, rebuilding, and reconnecting of human communities, environmental stewardship and civic life.Participants leave with resources for implementing interdisciplinary,place-based, and inquiry-driven sustainability projects, and receive implementation support from CELF throughout the academic year.

• Civic ScienceInquiry to Action is a semester- or year-long program that engages educators and students in project-based STEAM learning outside of the classroom. Using our Inquiry-to-Action framework, this program trains teachers to engage students in hands-on learning to identify, analyze, and solve real-world environmental issues that impact their school communities. Exploring cross-curricular inquiry pathways such as air and water quality, biodiversity, waste, and infrastructure, students visit local green spaces to collect data, develop action plans, and share findings and solutions with field experts and decision-makers during our culminating annual Student Symposium events.

  Expenses $412,500
