Students will launch the sphere-cover challenge by testing quick paper-wrap ideas, identifying measurable criteria and constraints, and connecting early observations about gaps, overlap, and waste to the problem of flattening a sphere.

Students will generate and compare multiple one-piece sphere-cover concepts, use geometric evidence and projection comparisons to justify a final team choice, and prepare a measurable prototype plan for the next phase.

Students will present and defend their revised one-piece paper sphere cover, compare it to a matching map projection, and use measurement evidence and revision history to explain efficiency, distortion, and design trade-offs during the Sphere Jam Showcase.
