Welcome to My Domain. 00:00:00
In just a minute, we'll get to the hands-on activity, which will require that you use 00:00:06
different shapes in designing airplanes. 00:00:10
Before we do, let's take a look at Riverdeep Interactive Learning's Destination Math Tutorial. 00:00:13
It's available free to NASA Connect educators. 00:00:17
You can get to it from the NASA Connect website. 00:00:20
It's part of the Mastering Skills and Concepts III section of Destination Math. 00:00:23
With this lesson, you will explore the geometric and algebraic characteristics of basic shapes. 00:00:27
Teachers, this is an excellent tutorial that can give your students information and assistance 00:00:32
as they prepare to do the hands-on activity for the show. 00:00:38
In this tutorial, Digit explores parallelograms, trapezoids, and right triangles while examining 00:00:41
the flags of some of the countries in the United Nations. 00:00:47
Many thanks to Riverdeep for providing NASA Connect with this exciting instructional technology 00:00:50
enhancement to our show. 00:00:55
Now, let's do an aircraft design activity, which you can do in your classroom. 00:00:57
We're from Pulaski Middle School. 00:01:02
Here in New Britain, Connecticut. 00:01:08
NASA Connect has asked us to show you this show's hands-on activity. 00:01:10
Here are the main objectives. 00:01:14
You'll use algebra to calculate wing area and aspect ratio. 00:01:17
You'll use a portable glider catapult to analyze wing geometry. 00:01:21
You'll design, construct, and test an experimental wing. 00:01:25
And you'll work in teams to solve problems related to wing design. 00:01:28
The list of materials you'll need for this activity can be downloaded from the NASA Connect website. 00:01:32
The class will be divided into groups of four. 00:01:37
Each group will use a portable glider catapult, or PGC, which your teacher made previous to this activity. 00:01:39
Good morning, boys and girls. 00:01:45
This morning, NASA has designated this class as Aeronautical Engineers in Training. 00:01:46
Your job is to test current wing designs based on distance traveled, glide, and speed observations. 00:01:51
From your analysis of the data that you collect, you will have the task of designing and testing an experimental wing to achieve maximum distance traveled. 00:01:59
First, cut out the templates for the fuselage, wings, and horizontal stabilizers. 00:02:11
Place the templates on the meat trays and trace around the templates. 00:02:16
Cut out the shapes. 00:02:19
Tip a piece of masking tape to the nose of the fuselage to prevent the nose of the fuselage from breaking. 00:02:21
Students will calculate the wing area, the wing span, the root chord, the tip chord, and the average chord for each wing. 00:02:26
The average chord can be calculated using this formula. 00:02:33
Next, have students calculate the aspect ratio for each wing using the formula wing span divided by average chord. 00:02:38
Record all values onto the data chart. 00:02:45
Prep the launch area by measuring 12 meters from the PGC. 00:02:48
Mark the distance at 1 meter intervals. 00:02:51
Place tables or desks of equal height to the launching line to elevate the portable glider catapult. 00:02:54
Place a book with a height of approximately 5 centimeters under the front portion of the PGC. 00:02:59
Select a wing shape to test. 00:03:05
You will be testing four different shapes. 00:03:07
Delta. 00:03:09
Oblique. 00:03:11
Straight. 00:03:13
And swept back. 00:03:15
Attach a small binder clip to the aircraft to give it some weight in order to achieve maximum distance traveled. 00:03:17
Position the aircraft on the PGC. 00:03:23
Using a rubber band, pull the aircraft to the launch position. 00:03:25
Then announce, 00:03:28
Prepare the flight deck for aircraft catapult. 00:03:30
5, 4, 3, 2, 1, launch! 00:03:34
You will conduct five trials for each wing shape. 00:03:43
Measure the distance traveled in centimeters and record the value onto the data chart. 00:03:47
Record your observations on glide and speed ratings using the scales provided from the lesson guide. 00:03:52
From the data collected, each group will design and construct their own experimental wing. 00:03:57
Design your wing to fly farther than the original test wings. 00:04:01
Okay now, how successful or unsuccessful was your experimental design? 00:04:04
What were the factors? 00:04:09
Resume. 00:04:11
Mine had a lower aspect ratio. 00:04:12
Big one. 00:04:15
Mine had a better swept back wing. 00:04:16
Special thanks to the AIAA Connecticut section and the AIAA mentors who helped us with this activity. 00:04:19
Thanks. We had a great experience today. 00:04:27
And we encourage teachers to visit our website to learn more about the AIAA mentorship program in your area. 00:04:30
