Assess students' ability to design a simple classroom recycling and composting plan for Grades 3-5: identify which items to recycle or compost, propose labeled bins and a collection schedule, assign student roles and signage, describe safe sorting and basic hygiene, suggest a simple way to measure or estimate waste diverted (counts or small weight estimates), and explain how each element reduces waste and supports classroom environmental stewardship. Evaluate feasibility, clarity, and expected waste-reduction impact.
