🛠️ Concept Sketch Critique

Teams sort individual sketches into promising directions using a criteria matrix that includes user desirability, clarity of welcome message, likely chain reaction, and material feasibility. Students give feedback to 2 peers, receive feedback, and revise one sketch before the team combines ideas into a single annotated concept sheet. The teacher checks each team’s selected direction as a gate before Phase 4, and teams record strengths, needs, and next steps in their engineering journal with a photo or revised drawing.
