<p>While school campus grounds are ubiquitous in urban landscapes, their potential for Urban Civic Ecological Education is often unrealized, limiting them to greening and beautification roles. This article presents a case study of Commonwealth Secondary School (CWSS) in Singapore, examining the development, challenges, and opportunities of transforming a campus landscape into a living laboratory that helps integrate urban ecology into a school community. Through an analysis of the decade-long development of the school’s physical spaces, educational programs, and community partnerships, it explores a replicable working model for Urban Civic Ecology Education. This case shows that campus grounds can be designed to engage students through hands-on activities to support teaching about ecological knowledge, research and data collection skills about agriculture and biodiversity, and environmental stewardship. It has been supported by external stakeholder groups, including government agencies, environmental NGOs, educators from other institutions, and the local community who guided tours, took part in tree planting activities, and harvested crops. However, the case also highlights the fragility of a siloed project reliant on a small group of champion teachers, with tenuous community engagement, and operational friction between ecological goals and conventional maintenance. Despite such challenges, the CWSS initiative underscores the critical roles that school grounds can potentially play in educating students while actively regenerating the social and ecological fabric of urban environments.</p>
