Problem/purpose: How do changes in two different characteristics (variables) of the ring-wing glider affect its flight patterns?

Hypothisis: We predict that if we put a 45 degree angle on the front ring at various angles that it will cause spin and cause the glider to go farther.

Materials: 5 straws and a piece of graph paper, tape, scissors, measuring tape

Procedure (detailed): Our gliders were not correctly made and are all completely different but our plans were supposed to be that there was the same sized back ring (12long 2wide, two squares overlapping) with the majority of the tape on the right side of the back ring. we were going to change the front ring and put it at various angles and placement (9 long and 7 wide, two squares over lapping). Then for the test one of us would throw all three gliders down the hallway from the same spot and measure it from that spot with the measuring tape.

Details of each glider: G1: The straw is taped to the out side of the loops, the front ring is sl1ghtly squared, and the back ring is round. The back ring size is two wide and 7 long. The front ring is two wide and 8 long G2: The straw is taped on the in side of the loops. The front ring is slightly squared and on the right side, and the back ring is round. The back ring side is 2 wide and 9 long. The front ring size is 2 wide and 7 long G3: This glider’s straw is taped outside of the ring, with (like the other gliders) a most of the tape the back ring on the right side. Its front ring is pointing slightly to the right. The back ring size is 2 wide and 12 long. The front ring is 2 wide and 8 long G4: It has more tape on one side then the other side and the front loop is a little side ways and the rings are taped on the outside of the straw. The back ring size is immeasurable because it is not made of graph paper. The front ring is 2 wide and 7 long G5: The tape is on the out side of the straw the rings are on the out of the straw the rings are a little side ways and tape is sticking out every were the front ring is little to much back because in the front part of the straw is sticking out G5 is missing and the ring sizes can not be recorded.

List of Control Variables: The gliders are all not the same and we were only supposed to change the elevation/angle of the front ring. We did not keep anything the same in ANY of the gliders and they were all completely different and we should’ve kept the back ring the same.

results and observations: G3 was the one that showed the best results almost doubling the others, it was also our prototype

Conclusions: First off all the gliders in our group are completely because we didn’t write down what we had to keep the same and what we had to change so none of the gliders had one characteristic that was all the same on each glider supporting my statement that they are all different. We have failed to reach our objective of finding out which angle makes the glider perform the best.
