Evaluate early learners' ability to analyze and classify familiar household items (clean paper, soiled paper, cardboard, food scraps, fruit peels, plastic bottles, metal cans, glass, diapers) into recycle, compost, or landfill. Students should sort real or pictured items, give simple age‑appropriate justifications referring to material, cleanliness, and biodegradability, predict consequences of mis-sorting, and respond to teacher prompts that probe reasoning; include expected answers, common misconceptions, and extension questions to deepen analysis.
