Eli Clem  Ju Ri     Problem : does making the rings and straw shorter, making it go farther? Hypothesis: If I make the lenth of the straw smaller, then it would probably make the glider fly farther. Materials: You will need: A straw, some scotch tape, grid paper, rule(optional), scissors. Procedure: First, take a rectangle grid paper and cut 12 squares on the grid paper and 2 squares across. Now, take the straw and ruler and cut off 5 cm of the straw.  3. Cut about 1 – 1.5 cm of tape. Cut in half and roll into a roll, from top, with one half of the tape.

4. Place rolled tape at very end of the straw. Then take the bigger ring (or longer piece of paper) and put one end of the paper and stick it in the middle of the rolled tape. Then take the other end and do the same.

5. Take the other half of the tape and put it on top of both ends and make sure there isn’t excess tape on the end, only a little bit for it to balance to ring. Then, do the same on the other end with smaller piece of paper.

__ How to hold your glider: __ You have to hold around, estimating, the middle of the straw. Then throw at a medium hard throw with it angling almost straight, but up.      Controlled varibles:   Force of throw - C   Postion - C   Height - C   Held on straw - independent   Angle - C

 __ Obsevations __   Conclusion We were wrong about the hypothisis because the prototype went further by sixty-three centimeters. Sources of error: How hard I could have thrown it. <span style="display: block; font-family: 'Calibri','sans-serif'; font-size: 22pt; line-height: 115%;">inproper measurements.
