Assess young learners' ability to analyze and sort common household items into "recyclable," "compostable," or "trash." Present 8–12 simple items (e.g., paper cup, banana peel, plastic wrapper, cardboard box, glass jar, soiled napkin) and require students to place each item in the correct category and provide a brief child-friendly explanation (1–2 sentences) focusing on material type and contamination. Scope: everyday household materials, basic compost/recycle rules, and simple justification appropriate for Pre-K–Grade 2.
