📏 Hershey Prototype Test Bench

Teams build quick paper models of their rectangular prism and square pyramid from their selected nets, then run the same test protocol on both: measure dimensions with rulers, verify calculated volume against the target, and compare surface area as material use. Students record results on a shared data table, note build problems such as misaligned tabs or unstable faces, and flag whether each design meets the brief. Close with a brief whole-class calibration on correct square versus cubic units before teams finalize test notes.
