Less packaging or more protection? Compare both requirements

Evaluate material use alongside protection in an invented design task.

Two paper package prototypes can make a trade-off visible. Measure or describe them against the same criteria, then explain why this small model comparison cannot establish a product's complete environmental impact.

A smaller package may use less card but protect the paper model less well.

One improvement may affect another criterion

Compare both designs using the same criteria. A claim about total environmental benefit would require evidence beyond this small paper-model test.

Agree on criteria. Compare each design. Explain a trade-off.

One criterion does not establish overall environmental impact.
