Mission
The organization's mission is to establish sustainability as an integral part of every child's PreK-12 learning experience. By integrating sustainability across subjects and grades, we can equip students with the knowledge, skills and attitudes that will help lead to a sustainable future for everyone. CELF programs use sustainability as an integrating context for teaching and learning, decision-making, civic engagement, community partnerships and campus practices. The lens of sustainability transforms curriculum, school operations, physical surroundings and school-community activities and fosters the cultivation of engaged citizens.
Program accomplishments
- 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.Expenses $39,662
- Civic ScienceCivic Science 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 $439,309
- Professional development and TrainingThe concepts of sustainability are universal, but every district and school starts from a different place in implementing sustainability education. CELF customized professional development (PD) helps schools infuse curriculum and school culture with education for a sustainable future. PD services include: gap analyses of curriculum; on-site Education for Sustainability training and resources (specific to grade level and school or district needs and interests); and review of facilities green infrastructure improvements to help infuse projects into curriculum. Through half-day workshops to multi-year engagements, we provide a framework for integrating sustainability concepts into curricula, community, and culture, helping teachers connect students to place-based learning opportunities in the community, create whole-school action plans, and activate student civic engagement.Green Careers Speaker SeriesAs student interest in sustainability grows, CELF helps students see how their interests and community concerns can be channeled into potential career pathways by connecting them with professionals working in a wide array of sustainability focused careers. CELF connects classrooms directly with industry professionals across sectors to explore opportunities for applying sustainability and systems thinking in their career planning and aspiration.Expenses $140,733 · revenue $11,100
