Test grade 6-8 students' understanding of how urbanization alters land use (impervious surfaces, loss of green space), increases stormwater runoff (reduced infiltration, higher peak flows), and impacts local ecosystems (water quality, habitat fragmentation, biodiversity) and community resources (flooding, infrastructure strain, public spaces). Assess ability to explain cause-and-effect relationships, interpret simple diagrams or basic data, and identify common mitigation strategies such as green infrastructure, permeable paving, and retention basins.
