=__GLIDERS!__ = **Question:** Does the length of the straw change the distance it travels? **Hypothesis:** if the length of the straw is smaller the glider will not go as far because the strips are too big for the stra **Materials**: Paper,tape,scissors,straw. 1. Get a normal straw 2. Get paper that’s 2cm wide. And 14cm long strip of paper and get a 3cm wide and a 24cm strip of a paper.the straw goes inside the rings. 3. Get the big strip of paper and overlap it 4cm and get the small strip and overlap it 1 cm. With the bigger strip sure you make the straw one cm out of the ring. And the smaller strip will sit exactly on the strip with no extra pieces sticking out. 4. ready to fly them! Independent Vairable- We change the length of the straw Dependent Variable- It changed the distance the glider travles Controlled Variables- The width of the strips, the length of the strips, the amount of tape we use, the same tape, the same paper,the same type of tape,the power,the way we throw it,the same overlap,the same person that throws it. **Procedure-** When flying the glider make sure your feet are planted on the ground. Point to where you want it to go,place the glider where your ear is and bring it back, and take one step and throw it. Make sure you hold the glider in the middle. When we measuere the distance it travles, we measure from the front ring. While testing and it hits a wall or the celing we do a re-test.Also make sure that the glider and the floor are parallel
 * Prototype Details: **
 * Variables **

Glider 1 is 16 cm length Glider 2 is 18 cm Glider 3 is 20 cm Glider 4 is 22 cm Prototype is 24 cm. the farther it went. || **Conclusion:** Our hypothesis was validated. As the straw length increased it increases the distance the glider flew. The evidence I have to support this claim is in our graph showed that the larger the straw in length, the farther the glider will go. We had one data point in our experiment when the straw length the biggest at 24 cm, the glider flew the best. And it did not fit the trend. Our data is not completely reliable because we couldn’t completely control the power, the amount of tape and the overlap. To better confirm out results we would, properly make a machine to to make sure each throw is reliable.
