__Question__: Will the length of the back ring affect the flying distance?

__Hypothesis__:

If we decrease the length of the back rings, then we predict that it will increase the distance because we shortened the length in the rings and that will make it lighter so it can go farther.

__Materials__: 1. tape 2.Some straws

5.Ruler

Our data shows the shorter the ring the longer it flys.

The realationship between the dependent and independent variables when the size of the ring goes down and the avarage goes up.

The source of error is, we had a hard time throwing the glider the same way each time. Another sorce of error is keeping your arm in the same place. Also another error is measuring, and also keeping the ring straigt. We would make our eperiment better by thorwing it the same height and the same speed and out the st

=__claim and evidence chart__= our claim is: The shorter the back ring makes the glider not fly as long. Our evedince is: The shorter the ring the longer it flys, and the longer the ring the shorter it flys. The longer one is 437.4 the shorter one 632 and the odd one out is 290.2
