 * Problem: How do we make the glider fly better? We can make the glider fly better if we only change one thing and no others.

Hypothesis: **  ** Materials: **     Procedure: First you get a straw and some tape and graph paper. Then you take the graph paper and some scissors and cut a length and a width and take some tape and take the graph paper and roll it in a ball and put tape on the edges of the paper then take a measuring tape and the glider and measure the distance it flew.
 * The longer the back wing is of the glider, the better it would fly straight and further distance. **
 * **straw**
 * **tape**
 * **scissors**
 * **graph paper**
 * ** tape measure **

Details:We made the glider with a normal straw with normal size. 2 square grid paper boxes wide. Every glider had a different length of the back ring. The rings are taped on the front and back wing. And the alignment is crooked big time its crooked to the left.  Glider one back wings length was 11cm long it flu 272cm. ** Glider two back wings length was 17cm and flu 451cm.

** ** Glider three back wings length was 21cm long and flu 521cm. **** Glider four back wings length was 19cm and flu 510cm. **** Glider five back wings length was 16cm and flu 269cm. **

**Control Variables: The force of throwing it, same person throwing the glider, amount of the smoothness of the glider's wings, where you will hold the glider.**     The length of tape stayed the same.        The back wing stayed the same.      The straw stayed the same.          The only thing that has changed is the back wing but the slant had stayed the same and the width of the front wing has stayed the same but the length of the back wing has changed.

 * Glider 1

 * Glider 3
 * Glider 4
 * Glider 5


 * Conclusion: **

**We found that glider three flu better because it was bigger than our prototype but bigger than that it would not fly. So we had to make it a certain length.**

It doesn’t have to be longer the back wing for it to fly better.
 * What do your results tell you?

**   **   Was your hypothesis correct? explain? **   **     No it wasn’t the longer the back wing it flu better but not to big. ** How can we make the test more fair? By useing the same person to through the glider. Holding the gliders in a similar spot each time. Standing in the exact same spot when throwing the gliders.  ** What Other observations did you make? **     **//__ Glider One __//** Glider one went straight and turned to the right. Glider one back wings length was 11cm long it flu 272cm. **//__Glider Two__//** Glider two went straight but turned to the left. Glider two back wings length was 17cm and flu 451cm. **//__Glider Three__//** Glider three did some flips though the air. Glider three back wings length was 21cm long and flu 521cm. Glider four turned to the left. Glider four back wings length was 19cm and flu 510cm. **//__Glider Five__//** Glider five went straight. Glider five back wings length was 16cm and flu 269cm.
 * //__Glider Four__//**
