=Glider= __**Question:**__ Will the mass of the tape affect the flight of the gliders?
 * Brett, Brad, and Jaden.

__**Hypothesis:**__ If we increase the tape length by 10cm the distances should be farther because the mass of the gliders should glide in the air.

__**Materials:**__ 4 Straws Paper Scissors Ruler Front and back circles are the same the length of the straw are same and distance from the front and back circles. Throw it when the back ring is pointing down (softly) Length of the tape.
 * __Control variable:__**
 * __Independent varable:__**

Distance of the Glider Flies
 * __Dependent varable__**

__**Characteristics of Prototype:**__ __**Back Ring**__ 10 squares long, 2 squares wide not over lapped

__**Front Ring**__ 7 squares long, 2 squares wide not over lapped

The straw is taped on the inside of rings

The length of the straw 17.6cm

Front ring does not stick out. Back ring is taped to the end of the straw

Distance between the rings: 10.8 cm

__**Test Gliders(length of Tape)**__ __**1. No tape**__
 * __2. 10cm of tape__**
 * __3. 20cm of tape__**
 * __4. 30cm of tape__**
 * __5. 40cm of tape__**

__**Procedure**__ || 2. Throw at 45 degree angle. 3. Throw softly. 4. Put arm forward. 6. Let go. Thrown at different angles.
 * 1. Hold glider behind head, arms length.

3. Hitting ceiling or walls. We learned that with less tape, it goes farther. ||
 * __Possible Errors__**
 * 1) Thrown at different angles.
 * 2) Thrown with different amounts of power.
 * __Things Learned__**

__**Conclusion:**__ Claim: The greater the mass of the tape decreases the length of the flight. __**Evidence:**__ The length of the flight dip downs as the mass increases. Data) Averages Glider 1 Glider 2 500cm – no tape 309cm – 10cm of tape Glider 3 Glider 4 159cm – 20cm of tape 303cm – 30cm of tape Glider 5 321cm – 40cm of tape

There is a massive drop in Glider 1 to 3. The glider 4-5 increases by the length of glider 3 but still below glider 1 and 2. There were a few sources of error, such as: the glider hitting the ceiling, the wall, and going into the boys and girls washroom. Also, when Jaden threw it, it may have not been on the correct angle each time or thrown with the exact amount of power. We thought of getting a robot to throw it because Jaden did not throw it accurately.
