Assess students' ability to analyze the lifecycle and environmental impacts of a single-use plastic water bottle by examining production (raw materials, manufacturing energy and emissions), use-phase issues (resource consumption, contamination risk), disposal pathways (landfill, incineration, recycling, litter), and alternatives (reusable containers, biodegradable materials, policy and behavior changes). Tasks include comparing environmental trade-offs, interpreting simple data on emissions and waste volumes, and proposing realistic mitigation strategies for middle school learners.
