Assess students' understanding of how recycling, composting, and waste reduction benefit communities and the environment by testing key definitions, common recyclable and compostable items, simple classroom/home practices to reduce waste, and the environmental and social benefits (less landfill, resource and energy savings, pollution reduction). Include multiple-choice and short-answer items that ask students to identify suitable disposal options, explain benefits in everyday terms, and analyze short scenarios to recommend waste-reduction actions.
