🛠️ Colony Build and System Trial

Students assemble the main base on cardboard, connect labeled living, laboratory, energy, and food modules, and run the first planned test on their chosen system. They measure results with cups, timers, observation notes, or light comparisons, then add a short end-of-build voice note naming one science idea used, one design choice made, and one crew health or safety challenge. The model and test notes become evidence for later revision.
