Assess students' ability to design a complete sustainable community garden for a 100-square-foot lot that maximizes food yield, conserves water, and stays within a $200 budget. Students should submit a scaled layout showing beds and spacing, a plant selection and succession plan emphasizing high-yield, climate-appropriate crops and companion planting, a water-saving irrigation and mulching strategy, a simple materials and cost breakdown under $200, a basic yield estimate and maintenance schedule, and a brief neighborhood engagement plan (roles, volunteer schedule, sharing/education activities). Evaluation emphasizes practical problem-solving, simple calculations, and clear written or visual communication suitable for grades 3–5.
