Problem/purpose: How do changes in one different characteristics (variables) of the ring wing glider affect its flight patterns? ** Hypothesis: We thought the glider would fly farther with the back wing 16cm long and 4 cm wide.We keep the front the same. ** Materials: Straw, Graph paper, Scissors, Tape,Ruler,Measuring tape, Paper. **
 * __ This report will include: __****

Details of each glider: (The length of the straw was 10cm long,the front ring was 2cm wide and 10cm long,The back ring was 10cm to 16cm long and 4cm wide to 4 cm wide) **
 * Procedure, (detailed):Step 1: The first step was to get the materials. We then used a straw and we cut 2 peaces of paper and cut them 10cm long and 2cm wide, the back was 16cm long and 2 to 4 cm wide.W e made the gliders loop bigger in the back and the same in the front. **** Step 2: We tried holding the gliders in the middle and it seemed to work very well. Step 3: we tested our work out and the results came very well. **
 * List of Control Variables:** ** The things that stayed the same was the straw length and the front ring stayed the same. The same person throw the glider everytime so there would be the same speed of the throw and the same strength. The person stayed at one spot and throw it there every time. **

G1: This glider fly’s well in a strait line.This gliders back ring is 2cm wide and 16 around and the front ring is 2cm wide and 10cm around. G2: This glider turns to the left and fly’s ok.This gliders back ring is 4cm wide and 16 cm wide and the front ring is 2cm wide and 10 cm around. G3:Doesn't fly well.This gliders back ring is 4cm wide and 16 cm around and the front ring is 2cm wide and 10cm around. G4: This glider spins and turns up word.This gliders back ring is 2cm wide and 16cm around and the front ring is 2 cm wide and 10cm around. **
 * Results and Observations:
 * gliders || trial 1 || trial 2 || trial 3 || average || ||
 * g1 || 500cm || 680cm || 800cm || 300cm || ||
 * g2 || 541cm || 323.5cm || 268cm || 273cm || ||
 * g3 || 672cm || 120cm || 281.5cm || 552cm || ||
 * g4 || 263cm || 187cm || 260cm || 76cm || ||

1. What do your results tell you?
 * Conclusions: (4 questions given) **
 * The first one was the instructed one and it flew well.On the second one we changed the back ring to 16 cm long and it flew a little futher. On an other we changed the back ring wo 4cm wide and it flew the furthest out of them.On the last one we made the straw shorter and it didn't work well it just flew everywhere**.

2. Was your hypothesis correct? Explain. The hypothesis was correct and the results came out well. All the gliders flew well but one

3. What other observations did you make? All flew well but onebecause it flew up word.

4. How could you make your tests fairer? By throwing at the same speed, with the same person,at the same place, and hold your finger at the same place on each glider.(In the middle)
