Problem: Does a shorter straw go farther, then a regular size straw. Hypothesis: We thought that the shorter straw would make the glider fly further then the longer straw. Materials: Tape, Paper (Graph paper recommended), Straws, and Scissors. Procedure: 1st step: Cut graph paper into rectangles, one medium size rectangle and one small rectangle. 2nd step: Take two centimeter of tape and put the straw in the middle of the two centimeter piece of tape. 3rd step: Get the small paper rectangle, and put the small side exactly vertical from the tape and connect it to the other side. (The small ring is your front and big ring is the back) 4th step: Do the same thing with the bigger rectangle. Description of prototype. 5th step:Remember, repeat this test 5 times and find the average distance for each glider. ==Length of straw; 19.9cm. back ring; 3cm wide, 17cm round. Front ring; 2cm wide, 13cm round. ==

Observation: we found that the shorter straw was the worsed glider and the lng straw made for a better air time. control variables: Same person throwing the glider. At the same hight, same strength and the same angle. Sources of error: we dont know if the measurements were exactly right. we don't know if the gliders were all thrown the exact same way with the exact same strength. Conclusion: our hypothesis was wrong we thought that the shorter straw would fly better but the longer straw was the best when it came around to test time. length (cm) || test 1 (cm) || test 2 (cm) || test 3 (cm) || average (cm) || (20 cm) || 144 || 472.4 || 527.3 || 381.2 || (17.3 cm) || 82.5 || 207.3 || 341.4 || 210.4 || (14.2 cm) || 136 || 259.1 || 54.9 || 150 || (11.8 cm) || 457.2 || 365.8 || 420.6 || 414.4 || (9.2 cm) || 66 || 67 || 304 || 145.8 ||
