Maveric, Brett, Nick, Damian Gliders **__Question:__** How does the width back ring affect how far the glider files ?

__**Hypothesis**:__ If we make the back ring longer it will make it glide further because it will get more air while it’s gliding.

__**Materials**__: 1.Tape 2. Scissors 3.Straw 4.Graph paper 5.Net books

__**Control vairibles**__
1. Same length of the glider. 2.The same ammount of tape. 3.Same length of the front ring. 4.The same person to throw the gliders. 5.the way you throw for the height. 6.and where you hold the glider when you throw it.

6. Let go.
__**Glider prototype characteristics**__ 1. Straw lenght 20cm. 2. Distance between rings 15cm. 3. Front ring 2 units wide 5 units long. 4. Back ring 3 units wide 10 units long (proto type).

We wll measure it with a measuring We will measure it from where we threw it right untill the back of glider.

 * __Analysis:__**

Ever since we changed the back ring its increasing and decreasing. Our hypothesis was not correct well we can't confirm that because we don't have enough information to confirm it. If we take the first three it seems as its decreasing but if you take the last three it is increasing. you can look at it a different ways. All we really need is more resaults/testing.
 * __Conclusion:__**

1. If the glider bumps in to things. 2. If one of the rings hit the throwers fingers. 3. If the thrower makes a mistake and throws it wrong. 4. If a person steps in the way or catches the glider. 5. If someone stepped on the ring before throwing it. Our hypothesis was correct; the glider with the biggest back ring caught more air and glided further.
 * __Sources of error__**

The greater the back ring increases the distance of the flight of our glider.

Build a robot to make the glider get thrown exactly the same time. Stay as steady as you can. Build a arm brace to make you stop when you throw it.
