Assess young learners' ability to categorize common household items into recycling, compost, or trash. The quiz covers basic material identification (paper, plastic, metal, glass, food/yard waste), recognition of contamination (food-soiled or greasy items, loose lids, plastic bags), and simple local-rule exceptions. Students will sort pictured or described items (e.g., apple core, pizza box, aluminum can, plastic bottle, paper towel, glass jar, yogurt cup) and give a brief justification for each choice. Designed for Pre-K–Grade 2, focusing on applied decision-making skills.
