🧠 Compost System Criteria Sort

Teams sort evidence cards from the waste audit, compost sample observations, and stakeholder notes into design criteria, constraints, and unanswered questions. The class builds a shared anchor chart naming what a school compost solution must do, what problems it must avoid, and how ecosystem science should guide decisions. Students use this chart to connect design choices to nutrient cycling, organisms, odors, pests, space, and plant growth.
