🧪 Mars Survival Systems Stations

Teams rotate through five short challenge stations for water recycling, food production, shelter protection, air supply, and energy generation using resource tokens, image cards, thermometers, lamp-and-shade radiation models, and simple habitat maps. At each station, students record one measurable need, one failure risk, and one trade-off in their Mars Colony Design Notebook. The class closes with a quick evidence sort to identify which system limits are non-negotiable for survival.
