📋 Evidence Check and Retest

Teams conduct a short second-round test of revised exhibit sections with classmates and use a competency checklist to verify that claims, visuals, and interactions now communicate accurate science and social studies evidence. Students explain one design choice, one trade-off, and one remaining weakness while classmates probe for evidence from maps, artifacts, observation notes, and user feedback. The teacher uses this checkpoint to determine whether teams are ready to advance to the next phase.
