Lesson Outline
Cardboard helicopters are made using a template. They are then launched from the highest inside space possible. Their flight time is recorded. The blade length is adjusted and the helicopter is relaunched and the flight time is again recorded. The process is repeated as long as possible. The blade lengths are plotted against flight times and an equation formed modelling the relationship. An optimum blade length is predicted from the model and then as many helicopters as possible are set at this optimum length an launched simulltaneously.
