🎥 Showcase Video & Fair Debrief

Students participate in the One School, Many Welcomes Fair with their team exhibition model, feedback wall, engineering journal, and prototype photos, then each student records a short video reflection. In the video, students explain the user need their machine addresses, describe how force, motion, collisions, energy transfer, and simple machines appear in the design, and cite at least one change made from gallery walk sticky notes, peer testing, or sixth-grade/community feedback. To close, teams sort final feedback into strengths, needs, and next steps and add one final journal entry with a photo or labeled sketch of the finished machine.
