NASA Connect segment exploring a web activity involving the design of a scale model. The video involves students in this activity to build, test, and record data according to the web activity.
Well, we sure have seen and heard a lot about how proportionality is used in science.
00:00:00
Now, bringing it to your computer desktop is NASA's Educational Technology Program Manager,
00:00:05
Dr. Shelley Kenright.
00:00:10
NASA researchers are constantly testing new technologies and designs for X-planes,
00:00:14
using everything from scale models to full-size flying machines that carry people.
00:00:18
These researchers evaluate their designs by using a basic formula of building, testing,
00:00:23
and recording their results.
00:00:28
I'd like to introduce a class of 8th grade students from Talladega County Central High School in Talladega, Alabama.
00:00:30
They are undertaking their own investigation into scaling and proportionality
00:00:36
using a unique model design challenge posted at the NASA Connect website.
00:00:40
Let's see what they're doing.
00:00:44
Welcome to Talladega County Central High School, Talladega, Alabama.
00:00:46
We have been asked by NASA to answer these questions.
00:00:52
Can you take a design that works on one scale and use it for an effective design on another scale?
00:00:56
Do you have to change the design when you change the scale?
00:01:01
To find out, we went to Norbert's lab and visited the NASA Langley Research Center Kids' Corner Model Shop website.
00:01:05
We reviewed the activity intro, collected our materials, and went to work building the eGrid, a paper airplane model.
00:01:13
We used the Model Shop extra activity to build the eGrid 2X.
00:01:21
We had to come up with ways to scale up the design plan,
00:01:26
determine the best materials to use to build the model airplanes, test flight, and record the results.
00:01:30
We learned that changing the scale of a working design is possible.
00:01:37
Making the model bigger revealed some design problems which were fun to solve.
00:01:41
We're even planning to increase the size of the model three times to see what happens.
00:01:46
We're also able to find information about aerospace grids and to see how NASA uses models in their research.
00:01:51
Jennifer, as the students from Talladega, Alabama have learned,
00:01:59
design and testing with scale models brings its own set of unique challenges and questions.
00:02:02
From Norbert's lab, viewers can try their hand at being a design engineer.
00:02:07
I encourage our viewers to visit Norbert's lab at the NASA Connect website
00:02:12
and to test their skills at building the eGrid 2X and other paper airplane models
00:02:16
that are available from a specially created online aeronautics model shop.
