Students will investigate how geometric forms affect light and shadow, establish initial lantern design criteria, and construct and revise physical nets as preparation for concept development.

Students will define a stakeholder-centered lantern problem, research existing geometric solutions, and translate measurable criteria into three distinct physical-net concepts. They will use coordinate sketches, symmetry, constructions, peer critique, and a weighted decision matrix to select and justify a shared design before construction.

Students will validate their selected lantern design mathematically, construct and inspect a precise physical net, assemble a prototype through repeated peer feedback, and collect quantitative baseline data for revision.

Students will use test data and peer critique to identify design failures, revise and retest a physical lantern net or structure, and document improvements through calculations, construction drawings, portfolio evidence, and draft museum materials.

Students will refine their exhibition materials through peer critique, present a tested geometric lantern and supporting design evidence, defend their engineering decisions, and reflect on their learning.
