__**Glider Project**__

__**Question**__.: Will the length of the straw affect the distance the glider will fly?

__**Hypothesis**__: If we change the length of the straw then it will have a nicer flight Because the amount of the straw cut off the lighter the glider will be.

__**Materials**__: Straws, Ruler, Tape, Paper, Scissors.

__**CONTROL VARIABLES:**__ 1) How Light you throw it. 2) How hard you throw it. 3) Direction of wind. 4)Dont hit walls. 5) Chairs. 6) Tables. 7) The spot you hold to throw it. 8) The way you throw it. 9)If you throw it upside down. 10) What angle you throw it in.

__**Independent Variable**__,
Change the lenght of the straw.

__**Dependant Variable**__, Masure the distance. Charecteristics of Prototype.

15 cm straw 3 by 14 loop front 3 by 15 loop back 10cm between rings.

__**Procedure**__ 1.Put tape where you would stand. 2.Stand stright. 3.Throw it medium. 4.Throw it in a 35 angle. 5.Then throw it like a dart 6. And last but not least measure it straight. 7. And throw it like a boss. 8.Hold it at the end of the back

__**Observations/Results:**__
 * gliders || flight 1 || flight2 || flight3 || flight4 || flight5 || average ||
 * 15 cm glider 1 || 330 cm || 340cm || 20cm || 360 cm || 390cm || 288cm ||
 * 20 cm glider 2 || 410cm || 500cm || 420cm || 510cm || 620cm || 492cm ||
 * 13 cm glider 3 || 390cm || 360cm || 180cm || 28cm || 180cm || 227.6cm ||
 * 6.5 cm glider4 || 171cm || 180cm || 170cm || 110cm || 140cm || 154.2cm ||
 * 9 cm glider 5 || 171cm || 120cm || 135cm || 170cm || 120cm || 143.2cm ||

__**//Conclusion//**__ The hypothesis was that if we change the length of the straw then it will have a longer flight, because the amount of the straw cutt off, the lighter the glider will be. This hypothesis was proven of false, the only reason why is because if you look at the chart above the 20cm did good in flight but the 6.5 cm didn't go pretty far but also look at the 9cm it did fly pretty far, I guess what im trying to say is the longer the straw the further the flight.
