Flight results

Hello, welcome back to my blog. This week for literacy we have been working on conducting our own experiment. Next week we will have full control of our experiment. This week my question was "what can you do to maximize the distance of a paper plane?" To do this I made 6 copies of the same plane and made different modifications on 5 of them.

Plane	Modification	Distance flown	Average Distance flown
Unmodified	None	360cm, 530cm, 430cm, 420cm, 530cm	454cm
Modification 1	Wings bigger	320cm, 240cm, 270cm, 330cm, 230cm	278cm
Modification 2	Flaps pointed down	490cm, 380cm, 440cm,. 420cm, 380cm	422cm
Modification 3	Nose	120cm, 190cm, 180cm, 260cm, 310cm	192cm
Modification 4	Flaps pointed up	140cm, 230cm, 150cm, 260cm, 120cm	180cm
Modification 5	Wings smaller	430cm, 420cm, 400c,cm, 380cm  450cm	416cm

Above are my results. As you can see the unmodified plane flew the furthest. This was extremely surprising because I thought that the plane with downwards flaps would fly the furthest. I thought this because downwards flaps create lift, making the plane stay in the air for longer. Comment if you think there are any other modifications I could have made?
