📈 Hypothesis

Each student writes a testable prediction for the compost solution change their team wants to try, using an If..., then... statement. The hypothesis must name one design variable such as airflow holes, material mix, lid type, sorting signage, or moisture control and predict a measurable result such as reduced contamination, less odor, faster decomposition, or better plant growth. Students add one sentence linking the prediction to ecosystem processes and prior evidence.
