So I designed the lab to measure how the change in rotor lengths of paper airplanes affects the time the helicopter remains in the air. RESEARCH QUESTION As the length (independent variable) of the helicopter’s rotors increase, how is the amount of time (dependent) the helicopter remains in the air affected? While keeping the drop height, room conditions, stop watch used, paper clip, and airplane material (controlled variables) the same throughout the experiment. HYPOTHESIS If the length of the airplane’s rotors increases, then the time the airplane remains in the air increases. MATERIALS • White printing paper • Scissors • 1 standard paper clip • Ruler • Measuring Tape • Stopwatch PROCEDURE • Constructing paper helicopters o Measure and cut strips of paper 2 cm wide.Measure and cut strips of paper 2 cm wide....
