The hypothesis, classic dart will go the farthest  with 2.5 meters is rejected. The data shows that Nick’s Paper Airplane went the farthest with an average of 26.5 meters. Classic Dart had gone more than 2.5 meters but still didn’t go as far as Nick’s Paper Airplane. It went with an average of 16.2 meters. The results of this investigation are useful since it can help with aerodynamics. it helps find a style that could be useful when flying an actual airplane. This investigation can be improved by trying to throw it from somewhat the same spot and/or by the same person, that would’ve made a more fair result. Another question that needs to be answered is, “Does shape take a large part of how the plane flies?”  With that I’ve learnt that the shape of the plane can change a lot more than what I had thought it could change.
