NASA Sci Files segment involving students in an activity to measure the differences in lift among varying wing sizes.
Hi, I'm Linda Zeromski from Mr. Tyson's 6th grade class at Tubal Dream Academy in Newport
00:00:00
News, Virginia.
00:00:09
What is the problem you're trying to solve?
00:00:10
We wanted to know if the size of the airplane's wings affected its flight.
00:00:12
What was your experiment?
00:00:16
Our teacher, Mr. Tyson, set up the test area.
00:00:19
Let's take a look at it.
00:00:21
The test area has a hinge with a 62-centimeter stick attached with a pushpin on the other
00:00:23
end.
00:00:28
The stick should go up and down freely.
00:00:29
Here is our test fuselage.
00:00:32
We will be attaching to it different size wings that we have made.
00:00:33
Why has the propeller been removed?
00:00:38
We are going to be using a fan to create our thrust instead of the propeller.
00:00:41
However, paper clips have been added to replace the weight of the propeller so that we keep
00:00:46
our variables the same.
00:00:50
Let's test it and see how it lifts.
00:00:52
Okay, we attached the small wing to the fuselage like this.
00:00:55
Now we turn the fan to a low speed.
00:00:59
I think we need to turn it up to medium because the wing is not lifting much.
00:01:01
Now look at it lift.
00:01:10
It is stable now, so add paper clips one at a time until the plane will no longer fly.
00:01:12
Wow, it held five paper clips and each paper clip is about 1.5 grams.
00:01:18
So our total weight added was 7.5 grams.
00:01:25
We decided to do the experiment at least two more times.
00:01:29
Now we need to take an average of all the trials for each wing.
00:01:40
Remember how to get an average?
00:01:44
Just add up all the numbers and divide by the total number of numbers you added.
00:01:46
Now we are ready to test the other wing.
00:01:51
Remember, keep all the variables the same during the experiment.
00:01:54
The only variable that will change is the size of the wing.
00:01:58
Let's take a look at our data.
00:02:03
The small wing held 7.5 grams of paper clips,
00:02:05
while the larger wing held 18 grams of paper clips.
00:02:09
So that means that since the larger wing lifted the most weight, it has the best lift.
00:02:12
Newport News isn't that far away.
00:02:18
Maybe we can test our new hypothesis.
00:02:20
Our new hypothesis is if you change the size of the wings,
00:02:22
then it will affect the lift of the plane.
00:02:26
We're not seeing any lift here, that's for sure.
00:02:31
We need these planes to soar. That's if we want to win the competition.
00:02:33
We need my man Jackie Chan to be here. He's a human flying machine.
00:02:36
Yeah, right. What could he do?
00:02:40
He's so cool. I just saw him in a movie and he flies right through the air.
00:02:42
I bet he knows all about the force of lift.
00:02:45
That's fake. That's just a movie.
00:02:47
No way. If he was here, he would help us win that competition.
00:02:49
Who's that? Is that who I think it is?
00:02:57
It's him, Jackie Chan.
00:03:01
You mean the martial arts master?
00:03:03
Nice to meet you, Mr. Chan.
00:03:18
Nice to meet you.
00:03:19
Hi.
00:03:20
Nice to meet you.
00:03:21
Nice to meet you, Mr. Chan.
00:03:23
Nice to meet you.
00:03:24
Hi.
00:03:25
Hi, hi, hi. I hear you guys need my help.
00:03:26
Uh-huh.
00:03:28
What do you do when you're faced with a challenge?
00:03:29
I just never give up.
00:03:31
Think about it before I do the stunt, but I'm not going to do it today. I'll do it tomorrow.
00:03:37
Can you help us?
00:03:43
I'm going to help you to build super-duper airplane. Okay?
00:03:44
Whoa.
00:03:52
Okay.
00:03:57
Wow.
00:04:02
See?
00:04:03
Do you think studying is important?
00:04:11
When I was 17, I got out of school.
00:04:13
Then slowly, slowly, I find out education is more important than doing the punch and kicking.
00:04:15
Good luck. I know you guys will be winners. Okay? Bye-bye.
00:04:21
Bye.
00:04:24
Thank you.
00:04:25
Thank you.
00:04:26
See you, Jackie Chan.
00:04:27
That was really him.
00:04:28
It sure was. You know, I just have those connections.
00:04:30
Yeah, right?
00:04:34
