Glider
//__**Problem**__-// How will the position of the front wing affect the flight?

//__**Hypothesis**__// - If we put the front wing back more will it fly further and longer? Because the more weight in the back will cause the front end to point upwards making it fly higher and longer in the air.

__//**Materials**//__ - Grid paper, Plastic straw, sotch tape, Sissors, Ruler. __//**Control varibles**//__ Staw length, Same size rings, Same amout of tape, Back ring in same position

//__**Independent varibles**__// Front wing in a different position

__//**Dependent varibles**//__ The distance the glider flies

__//**Prototype**//__ - 20cm plastic straw, 4'' of sotch tape, front wing is 12cm x 3cm back wing is 18cm x 4cm

__//**Proceedure**//__- Lay down a peice of tape then put your left foot on the tape and hold the glider in your righjt hand with three fingers in the middle of the glider. then rise your right arm behind your head and throw like a base ball. Take a measuring tape and measure from your left foot to the back of the glider in a straight line. Then record the measurement on the chart.

The angle the person is throwing. The measuring of the flit distance could be a little off. The power of the person that’s throwing. The standing of the person could be a little off. It could hit the wall, ceiling and the boys and girls bathroom. The holding of the position of the glider. Building the gliders just the same as the prototype prototype got rinkal.

 * __Analysis:__**
 * __Sources of error__**

__**The conclusion**__ From the data the hypothesis is right becuase there is a steady increase in the data, beside some of the outliers caused by the sources of error. From our changes to the prototype with the ring 15 cm from the back ring flew 602 cm and the change of glider 2 which was 11.5 cm.and it increased its flight to 643 cm.

__**Possibilities for further studies**__ To make it far you would need to have a robot to make the throws far every time so they would get the right distance because no human is perfect so that is why you would take a robot and tell it what to do. So that is what you would do because every time the human arm will not be back in the same spot at the same angle and so on.

There is a relationship from the position of the front ring and the distance the glider flies becuse, in the data there was a steady increase in the distance the glider flown with the front ring farther away from the back ring but the prototype has droped in the distance when flown because it was the oldest glider and had the most flight causeing it to become rinkled and tatterd.
