Evaluate young learners' ability to analyze everyday classroom and household items and decide whether each belongs in recycling, compost, or trash, giving a simple reason based on material type (paper, plastic, glass, metal), organic vs. non-organic, and cleanliness/contamination. Use picture-based items such as paper, cardboard, plastic bottles, glass jars, metal cans, food scraps, soiled napkins, yogurt cups, and diapers; students choose the correct bin and provide one short explanatory sentence appropriate for Pre-K–Grade 2. Assessment emphasizes classification skills, basic reasoning, and awareness of contamination and compostable materials.
