![]() In this way, engineers learn exactly how the craft reacts to the altered the control surfaces. When testing an aircraft model, engineers move one of the control surfaces during each test and leave the other control surfaces in its standard configuration. This engineering curriculum aligns to Next Generation Science Standards ( NGSS).Įngineers use the scientific method when testing their design models, changing one variable at a time and comparing it to the original configuration. Then they change one of the control surfaces and compare the results to their base glider in order to determine the cause and effect relationship of the control surfaces. They construct paper airplanes (model gliders) and test their performance to determine the base characteristics of the planes. Students use the scientific method to determine the effect of control surfaces on a paper glider.
