This Campfire session explores the use of altar-making as a visual and ritual practice in environmental education. Drawing inspiration from Día de Muertos and sacred commemoration traditions, the session invites educators and scholars to consider how altars—honoring endangered species, climate-impacted places, or ecological loss—can serve as powerful tools for civic reflection and hope. A brief presentation will share examples and theoretical framing, followed by a collaborative dialogue where participants will reflect on grief, resilience, and visual storytelling in climate pedagogy. Together, we will explore how classrooms might become sacred spaces of ecological witness—where images and objects carry memory, meaning, and a call to action.
