Test educators' ability to design and implement a classroom recycling and composting plan for grades 3–5 that reduces waste. Assess selection and labeling of recyclable and compostable items, bin placement and signage, student roles and routines, collection and composting schedule, contamination prevention and safety, simple measurement methods to track waste reduction (e.g., counts or weights over several weeks), and a brief lesson/assessment to teach and sustain habits; evaluate feasibility, age-appropriateness, and expected impact.
