If the straw’s lengths are different sizes would they fly further ?
Hypothesis ;

If the straw is shorter it would go further. -then if the shorter straw goes further then you know the longer straw is heavier then the shorter straw. I think this because, the longer straw has more weight on it then the short and then you know the longer straw is heavierthen the shorter straw ; Materials; a straw; paper; scissors; tape;measuring tape;

How to build the prototype:

To make the front ring you need to cut a piece of graph paper, 3 by 10 squares. then you need to make the back ring which is, 7 by 22 squares. you have to take the two rings you made, and tape them to the front and the back straw; then length of the straw is 20 cm

How to fly it ; you have to keep your gliders the same, height and force when your throwing your glider also your angle of your glider has to be the same, 180 digrees;
 * Glider #'s || Size || Trial 1. || 2 . || 3 . || average ||
 * 1 || 10cm || 238 || 369 || 407 || 338 ||
 * 2 || 15cm || 425 || 680 || 440 || 515 ||
 * 3 || 18cm || 358 || 404 || 446 || 403 ||
 * 4 || 19cm || 359 || 600 || 423 || 521 ||
 * 5 || 20cm || 400 || 325 || 410 || 378 ||

Conclusion : Are hypothesis was incorrect, Our data shows that the smaller the straw the = Sources of error;  = when you build it it might be all the same. when you trow it ,the force or the angle will be not the same.
