Question - Will the length of the straw affect the flying distance?

Hypothesis: if we increase the length of the straw, then we predict it will increase the distance because less wind in the straw will cause the glider to slow down.

Material used/need to use - 5 straws; grid paper; ruler; pencil; tape; scissors; net book;

Control Variables

 How hard you throw it

 How far your arm goes out when you throw it

 If you don’t throw from where you threw the first glider

 How high you throw it

 Where you aim to throw the glider

 Difference in the glider

 The length of the back wing in the glider

 The length of the front wing in the glider

 The length of the straw

 If the straw or the wing is bent

 The difference in where you put your rings

 The width of the front of the glider

 The width of the back of the glider

 The damage in the straws

 The damage is the wing

Independent Variable – Length of the straw

Dependant Variable - Distance it flies

Procedure - Hold glider in hand, hold so the bigger end is at the back, get ready to throgh, then trow it.
