Problem/purpose: We need to make the glider fly better by changing the back ring bigger and keeping the front ring the same size.

Hypothesis: I think if we change the front ring bigger and keep the back ring the same size. the front wing is smaller by couple sqaures and if we change the front ring the glider will do flips in the air

Materials: What you need to make a glider is graph paper,sisors,straw and tape

procedure(detailed): First take a straw and grap paper then take scissors how ever long you want. then loop the ring after you cut out ur sqaures.then you take tape and take the rings to each end of the straw. We made the same person throw the same strength and by the same height.

Details of each glider: G1:the front ring of the glider is alot to the right and the straw is bent a little. G2:the front ring is a little to the right. G3:the front ring is bent down a little and is smaller then the back ring. G4:the back ring is slightly to the left. G5:We couldnt find glider 5!

List of Control Variables: to tall, to short, how hard you through it, where you hold it in the middle or at the end of the gliders, who holds it

Results and Observations:
 * gliders || trial 1 || trial 2 || trial 3 || Average ||
 * G1: || 383 || 375 || 399 || 385 ||
 * G2: || 500 || 177 || 272 || 316 ||
 * G3: || 348 || 367 || 362 || 359 ||
 * G4: || 309 || 422 || 360 || 363 ||
 * G5: || 460 || 390 || 333 || 394 ||

Conclusions: 1) What do your results tell you? My results tells me that we can improve on our gliders  2)  Was your hypothesis correct? Explain no because some body in my class has a big glider. And its not a circle its a big square 3) What other observation did you make? We watched our glider fly and we need more strength.  4)  How could you make your test more fair? Too make the test more fair we can make the same person throw it and the same strength.
