Assess learners' understanding of the urban heat island (UHI) phenomenon: its physical causes (land cover change, reduced albedo, impervious surfaces, anthropogenic heat), impacts on public health (heat-related illness, air quality, vulnerable groups) and infrastructure (energy demand, pavement/rail damage, stormwater/transport stress), and policy mitigation/adaptation strategies (urban forestry, green/cool roofs, reflective surfaces, zoning, heat action plans). Items will require explanation, analysis of trade-offs and equity considerations, and evaluation of monitoring and effectiveness metrics.
