The student conducted an experiment to test how alterations to a paper airplane's design affected its flight. The airplane was launched six times with different combinations of a paper clip added to the nose and the elevator flaps positioned up or down. Observations showed the airplane with a paper clip on the nose traveled farthest, while one with just lowered flaps went the shortest distance. The student concluded the paper clip helped drag the airplane farther after landing, while lowered flaps kept one airplane aloft longer without other changes to assist its travel distance.
