Assess Grade 3–5 students' ability to apply environmental concepts by designing a classroom recycling and composting plan that reduces waste. Students should identify recyclable, compostable, and landfill items; design sorting stations with clear signage; create a weekly collection schedule and student roles; outline a safe indoor or outdoor compost setup and contamination-prevention steps; estimate simple expected waste reductions and monitoring methods; and describe how to communicate the plan to classmates and custodial staff. Include a brief rubric or checklist for implementation and evaluation.
