Helicopters are rotary-wing aircraft: The wing surface is rotated through the air to produce lift. In this activity, students make paper models that imitate the rotation of the rotor blades of a helicopter. Using tape from an audio or videocassette, students determine the number of rotations of the model as it falls through the air.
