Assess and compare three waste‑management plans—recycling, composting, and landfill—for a small elementary school. Students will evaluate each option's environmental impact (e.g., waste diversion, greenhouse gas potential), estimate simple costs (startup and recurring), and judge practical feasibility (space, staff time, student participation). Using provided data or scenarios, calculate basic metrics, rank the options, and write a clear, justified recommendation with implementation steps and trade‑offs suitable for grades 3–5.
