Assess students' ability to apply simple decision rules to sort common household items into recycle, compost, or trash bins. Scope includes identification of material types (paper, plastic, metal, glass, food scraps), recognizing contamination (soiled paper, food residue), basic compostables (fruit and vegetable scraps, napkins), recyclables (clean paper, empty bottles and cans), and landfill items (soiled plastics, non-recyclable wrappers). Use age-appropriate pictures or short scenarios for Pre-K–Grade 2; ask learners to choose the correct bin and provide a one-sentence reason. Include a few items that require simple analysis (e.g., rinse vs. discard, separate lids) to assess applied reasoning and safe handling.
