Problem. We changed the width of the back ring to see if it would make it fly in a greater distance of length. We think that if we took the back ring and changed the width it would fly better. If the width of the back ring was changed it would fly better then before.

Materials: 1: You will need a non bendable straw. 2: You will need some scissors to cut stuff. 3: You will need a sheet or two of graph paper. 4: You will need some scotch tape so you can tape the graph paper rings to the straw. 5: You would need masking tape to mark where you start and where the glider might land. 6: You will need a measuring tape to measure the distance. 7: You would need a duotang full of paper. 8: You need to make a chart so you can record. 9: A pencil.

Procedure(detailed):Step one: We got the graph paper we cut out the amount of squares in the graph. We folded the graph paper into a ring we taped the ring to the starws. Step two We got Flany to throw the gliders in the same spot at and with the same strenght We used a measuring tape to measure the length the gliders went Step five:We recorded our data of the gliders flights.

Details of each glider G1: front ring is 7cm long and 2 cm wide the back 9 cm long and 2 cm wide G2: front ring is 7cm long, 2cm wide. Back ring is 9cm, 5 cm wide. G3: front ring is 7cm long, 2cm wide. Back ring is 9cm long and 3cm wide. G4: front ring is 8cm long, 2cm wide. Back ring is 11cm long, 8cm wide. G5: front ring is 7cm long, 2cm wide. Back ring is 8cm long, 8cm wide.

List of control variables: 3.  Did the same person throw it. Flany 4. Was the straw the same length in each glider, 5. Same amount of tape front ring.  6. Same amount of tape of the back ring.  7. The length and width of front ring are kept the same.
 * 1) The way we throw it. We held it in the middle
 * 2) Is it thrown in the same place. In the cafeteria

Results and Observations: Glider One:It flew sucussful G2:It went crookedn then went straight again G3:It flew straight for a good distance then went down head first G4:It didn't go to far until the last test G5 Had to much weight and didn't fly good.
 * Gliders || Trial 1 || Trial 2 || Trial 3 || Average ||
 * G1 || 377cm || 520cm || 242cm || 379.67 ||
 * G2 || 399cm || 435cm || 124cm || 319.3 ||
 * G3 || 624cm || 310cm || 469cm || 467.67 ||
 * G4 || 274cm || 276cm || 403cm || 317 ||
 * G5 || 194cm || 210cm || 367cm || 257 ||

Conclusions: #1It flew better since weput more wieght on the back. Number two Our hypothesis was correct we predicted that if we put more wieght on the back it would fly further and we were right. Number three:If we put too big of a ring it goes side way and makes lots of turn int he air. Number 4 : Same person throwing, same straw, same tape same strenth when throwing in side our outside,a/c on, holded on the same place, throwing on the same line. The forth glider should have been kept the same at 7cm by 2cm not 8cm by 2cm so we messed up.
