Identify the hypothesis. Maria collected a tape measure, cardstock, and printer paper. She went to the hallway outside her science classroom to conduct her experiment. First she folded an airplane out of cardstock. She noticed the airplane was very sturdy because it was made of cardstock, which is heavier than printer paper. She then used the printer paper to fold a second airplane. The two airplanes were the same size and design. Standing in the same place for each throw , Maria threw the cardstock airplane ten times and used the tape measure to find the distance the airplane flew after every throw. She repeated the throws and measurements with the airplane made of printer paper. Maria recorded her data in her lab book and graphed the results so she could compare the distances of the airplane flights.
