🐠 Design Tank Showcase

Teams set up their scaled aquarium model, math card, design portfolio, and poster for a gallery walk with invited guests, classmates, and staff. Each team gives a short presentation explaining tank dimensions, volume, surface area, material choice, and one revision made after feedback or testing. Visitors ask questions and leave brief feedback, and students end with a quick team reflection circle naming one math insight, one teamwork strength, and one future design improvement.
