Students will launch the food-waste challenge, observe who is affected in their school community, gather first evidence from the cafeteria context, and draft the problem framing, user focus, and inquiry questions that will guide later research and design.

Students will deepen their investigation of school food waste by gathering information from observations, interviews, models, and source analysis; identifying root causes; comparing possible solutions; and preparing an evidence-based proposal for a prototype and communication system that fits their school community.

Students will turn research from the earlier phases into a school-ready food waste solution by studying effective examples, defining what they will test, planning roles and materials, building first versions, gathering peer and user feedback, and revising their prototype and PSA supports.

Students will implement their food-waste solution in a real school setting, collect evidence about how it works for users, and analyze results to decide what should be improved before sharing their impact.

Students will present their food-waste solution impact and complete a concise final reflection that connects prototype evidence, PSA media choices, community feedback, and their growth as sustainability coordinators.
