Physical Modeling Overview
Students work in teams of four to design, construct, and test a scale model of an emergency survival shelter that meets the engineering requirements stated in the challenge scenario. The team uses the Informed Design Process to clarify specifications and constraints; conduct research; generate alternatives; justify the optimal design; test, evaluate, and modify the solution; and communicate achievements in a class presentation and final design report.
The design criteria are: the shelter must be kept at an inside temperature of at least 45 °F when the outside temperature drops to 25 °F, the only heat source available is the body heat of the four team members, the shelter must be large enough for all four survivors to sleep side by side and sit up comfortably within it, and the shelter must sustain a 15 mile per hour wind and a snow load of six pounds per square foot.
