Guided investigation

Green Works: Model one relationship

Green Works: a prototype meets one criterion while approaching a stated constraint.

Green Works Grade 6 mission: Use the provided comparison and keep one condition fixed. Build evidence for this learning goal: Compare design choices using both a human need and an environmental effect.

Model

Criteria, constraint, and prototype

Run the baseline and one changed case. Keep the named controls fixed.

Criteria
meets the intended function; retains a measurable performance margin
Constraints
limited resources; safe operating boundary
Failure measure
Performance margin
Choose a design claim that names both a criterion and a constraint.
Evidence

Prototype test results

Commit a testable model and run the investigation to generate evidence.

Your criteria, constraints, measured failure, iteration, and tradeoff defense become inspectable engineering evidence.
