= The Airplane Design Challenge  =

// Design an airplane that returns the best results when tested for accuracy, distance and time aloft. //

Design :
**Plane #1**



**Results**
To calculate the average of each category, add each trial and divide the sum by 3.
 * || ** Accuracy ** || ** Distance ** || ** Time Aloft ** ||
 * **Trial #1** || no || 96 in. || 1.90 sec. ||
 * **Trial #2** || no || 89 in. || 2.40 sec. ||
 * **Trial #3** || no || 276 in. || 3.36 sec. ||
 * ** Total ** || no || 461 in. || 7.66 sec. ||
 * ** Average ** || no || 153.66 in. || 2.55 sec. ||

**Results**
To calculate the average of each category, add each trial and divide the sum by 3.
 * || ** Accuracy ** || ** Distance ** || ** Time Aloft ** ||
 * **Trial #1** || no || 96 in. || 2.10 sec. ||
 * **Trial #2** || no || 216 in. || 2.10 sec. ||
 * **Trial #3** || yes || 216 in. || 3.20 sec. ||
 * ** Total ** ||  || 528 in. || 7.4 sec. ||
 * ** Average ** ||  || 176 in. || 2.46 sec. ||

 * **Did you get any good ideas from the groups you were watching?**
 * **What techniques can you borrow?**
 * **What do the results of the different planes suggest about their designs?**
 * //**Hypothesize**//**: What specific design elements might make a difference when testing for accuracy, distance and time aloft? Why?**

Iterate :

 * Design a new plane**

Plane #3



 * Results**

To calculate the average of each category, add each trial and divide the sum by 3.

The fourth plane that failed miserably was not successful with the last fold we did with the wings. Also when our last plane was built we tilted the wings to the side and it seemed to work better, but when we tired it this time it didn't work out so well, and it was like we wonted the plane to fail .that was because we were all tried and wonted to go home.
