Paper packaging trade-offs: protection can cost material

Compare two prototypes against both requirements. A design may protect the model better while using more card, giving children a defensible compromise to explain instead of an exercise with one automatically superior answer.

Extra layers may improve this model's protection while using more paper.

State which criterion gets priority here

Ask which requirement each feature serves and what it costs in the other criterion. A reasoned compromise can be a successful design outcome.

Define protection and material criteria. Test both. Explain the compromise.

Which criterion was prioritised? Use a two-axis comparison.

There may be several defensible solutions.
