Assess students' ability (grades 3–5) to analyze a proposed schoolyard development by identifying effects on local habitat and biodiversity, predicting changes in water runoff and drainage, evaluating how space for play and learning would be reallocated, and weighing community trade-offs (safety, cost, recreation, ecology). Include tasks to interpret simple diagrams/maps, compare before-and-after scenarios, make evidence-based recommendations, and explain reasoning in age-appropriate language.
