Assess young learners' ability to classify common household items (e.g., paper, banana peels, plastic bottles, soiled paper, food scraps) into recycle, compost, or trash categories and to give a simple explanation of how each choice helps the Earth (e.g., saves resources, enriches soil, reduces pollution). Tasks include item-based sorting, one-sentence justifications, and comparing options to practice analytical reasoning; materials may be pictured or real objects.
