Hello, my name is Paula. My name is Gada. Our experiment project is about

2
00:00:08,660 --> 00:00:18,699
aerodynamics. We are going to do two different experiments. First experiment is

3
00:00:18,699 --> 00:00:26,679
about air resistance which is called DRAP. We are going to use a paper clip, a

4
00:00:26,679 --> 00:00:34,679
A reel, a thread, two pieces of carbon board, a long screw.

5
00:00:35,679 --> 00:00:38,679
I'm going to explain how to prepare it.

6
00:00:39,679 --> 00:00:42,679
We roll up a thread onto a reel.

7
00:00:42,679 --> 00:00:49,679
In the other side we tie two paper clips and we pass through the reel a long screw.

8
00:00:50,679 --> 00:00:54,679
We are going to hold the screw and letting free the reel.

9
00:00:54,679 --> 00:00:57,679
So the two paper clips are will fall down.

10
00:01:03,460 --> 00:01:07,459
Now we are going to do the same experiment but with two carboards on the side of the rim.

11
00:01:12,950 --> 00:01:15,950
The paper clips fall down slowly because of the draft.

12
00:01:15,950 --> 00:01:19,950
Mix an opposite force against the paper clips weight.

13
00:01:21,950 --> 00:01:28,480
Second experiment is about Goanda effect.

14
00:01:28,480 --> 00:01:36,480
This effect explains how a fluid touches the earth, takes a curved shape and it follows its curve.

15
00:01:36,480 --> 00:01:48,480
We are going to use a curved shape element, a square shape element and a cannon.

16
00:01:48,480 --> 00:01:55,480
We light a cannon and we put it behind the square shape element.

17
00:01:55,480 --> 00:02:00,480
We blow up the square shape and the candle keep light.

18
00:02:02,480 --> 00:02:11,750
We are going to do the same but we are going to change the square shape by a curved shape.

19
00:02:12,750 --> 00:02:16,639
You can see the difference.

20
00:02:18,639 --> 00:02:21,639
This is thanks to Canada in Fit.

21
00:02:22,639 --> 00:02:24,639
I hope you've enjoyed this video.

22
00:02:24,639 --> 00:02:26,639
And thanks for watching.

23
00:02:26,639 --> 00:02:27,639
Bye!

24
00:02:27,639 --> 00:02:42,419
Our experiment project is our...

25
00:02:42,419 --> 00:02:44,419
My name is Gala.

26
00:02:44,419 --> 00:02:46,419
Our experiment project is our...

27
00:02:46,419 --> 00:02:48,419
My name is Gala.

28
00:02:48,419 --> 00:02:50,419
Our experiment project is our...

29
00:02:50,419 --> 00:02:52,419
about aerodynamics.

30
00:02:56,419 --> 00:03:08,389
We light a candle and we...

31
00:03:08,389 --> 00:03:12,389
And now you can see the difference.
