Paper Planes 22|10|14

This week, room 2 have been learning about paper planes. We have been making our own paper planes & have modyfied them to make them fly further. At the end of the week, we will be having a contest to find the plane that can fly the furthest. I made five different models. We had to come up with an assertion to make our planes fly further. My assertion was that the more slender the plane is the further it will fly. Our best plane flew 8.47 meters & our worst flew 1.4 meters. Below is my best plane.

Today, the 24|10|14 we made scatter plots about our planes. This is mine.
My assertion is that the more slender the wingspan the further it will fly.

My assertion was right but wrong at the same time because the plane with the most slender wingspan came second. But the plane with the second most slender wingspan came first..
