This article provides a rationale and resources for teaching climate justice and civic engagement across the STEM curriculum in K-12 and higher education. It presents a culturally responsive approach to STEM teaching and learning that centers social justice issues arising from climate impacts, and energy extraction and development activities, with a focus on participatory and equitable solutions and actions. This approach promotes STEM curricula that introduce social justice issues into the classroom as an entry point for investigating the issues using STEM. A social justice approach allows students to make meaning of abstract and disparate STEM knowledge and skills through real-world issues aligned with their interests, experiences, identities, and communities. In this article, we provide resources for teaching STEM through climate justice and civic engagement that are being collectively developed by groups in Washington (WA) State, led by Deb Morrison at the University of Washington (K-12); Sonya Remington Doucette and Heather Price at local community colleges (Bellevue College and North Seattle College); and Irene Shaver at the WA State Board of Community and Technical Colleges.
