Cafeteria Waste Reduction Project

Grade 7ScienceMathEnglish21 days

In the Cafeteria Waste Reduction Project, 7th-grade students engage in a hands-on experience to devise a sustainable waste reduction program in their school cafeteria. Through scientific inquiry, mathematical modeling, and effective communication, students collect and analyze data on cafeteria waste, creatively design solutions, and advocate for implementation to the school community. The project aims to enhance skills in environmental impact assessment, data interpretation, engineering design, and public presentation while promoting sustainability awareness. Students also reflect on their learning journey and confidence in applying data-driven decisions to environmental issues.
