L.I:To use statistical and scientific methods to study the effect of of wing span and area on lift.
My wingspan is 21.7 centermetres.We had to make a paper air plane any different kind of designs.
We had to do step by step so it can be good.We had to throw it 10 times or more so we could get our measurement.When we have got our measurements you have to divide it by 10 and then that means you got your exact measurements.
My measurements were 3.233.
