🛠️ Rapid Paper Plate Prototype Build

Students individually construct a low-fidelity rotating paper plate model (2 plates, brass brad, cut rim, labeled oxygen and carbon dioxide arrows, plant and animal sketches). They focus on clarity for their specific user (e.g., 4th grader), using large labels and color coding. Students record Version 1 in their design journal with a dated sketch and a short note explaining how it addresses their How Might We question.
