**// Question: what will moving the front part of the glider back a centimeter do to the distance and time in the air? //** **// Hypothesis: we think it won't go as far or stay in the air as long. //** ** // materials: paper, straw scissors and tape // **

Prototype Details: Straw length: 24.6 cm Front ring Length: 6cm Width: 3cm Overlap by 0.4cm Back ring Length: 13cm Width: 3cm Overlap by 0.7cm Length between rings: 19.5cm Straw is taped on outside of rings Rings are a lined.

independant variable: the variable you change in the experiment. our independant variable is the front end of our glider that we move back dependant variable: the variable that stays constant and is changed only by the independant variabe. our dependant variable is the distance it flys control variabe: is the variables that we keep the same. 1. the person throwing the glider. 2. how hard you throw it. 3. how you hold it. 4. how the gliders made: 5. the length of the straw 6. how much paper 7. where the rings are placed 8. whether the straw is on the inner or outer side of the ring. 9. where we throw it  10. people around us

Procedures: Make a straight line on the floor. Put both feet on the line. Trevor will throw each time He will hold it about a quarter length back Use medium force Measure to the glider even if it goes a different way Measure to the back of the glider REDUE TEST IF IT HITS WALL OR CEILING

 * //__ CONCLUSION: __//**

Our hypothesis was validated. The front ring of the glider decreased the first time then didn’t really change after how far the glider flew. The evidence I have to support this claim is the graph it dropped the first time then stayed the same. We had one point that went a lot farther that the others and that was our prototype. Our data is not completely reliable because we could not completely control the strength it was thrown, how you hold it and the direction it flies in. To better confirm our results we would test it more often to see if it stays the same and try to build them as best we can to make them the same.
