Test students' ability to sort common household items into recycling, compost, or trash. Present simple pictures or descriptions (e.g., clean paper, pizza box with grease, banana peel, plastic bottle, soiled napkin, glass jar, aluminum can, food scraps) and require learners to apply basic rules—clean/dry and accepted materials to recycling, organic food/plant waste to compost, and greasy/contaminated or non-recyclable items to trash—plus a brief explanation for each choice.
