Assess students' ability to apply clear rules to sort common household waste into recycling, compost, and landfill bins. Include typical examples (paper, cardboard, glass, plastic bottles, food scraps, yard waste, greasy pizza boxes, soiled paper, diapers), ask students to justify placements and note simple preparation steps (rinse containers, remove lids, flatten cardboard) and contamination considerations. Designed for grade 6–8; emphasis on practical application in everyday scenarios.
