0
00:00:00,000 --> 00:00:18,000
It has been a bit difficult, but after the effort, we made it.

1
00:00:18,000 --> 00:00:22,000
First, we hammered the stick.

2
00:00:22,000 --> 00:00:28,000
Secondly, we hammered the squat.

3
00:00:28,000 --> 00:00:33,000
After that, we put the bracket at the top of the stick, covering the generator.

4
00:00:33,000 --> 00:00:36,000
We put the spiral in front of the generator.

5
00:00:36,000 --> 00:00:38,000
Then, we put the battery.

6
00:00:38,000 --> 00:00:43,000
And then, we connect the cables.

7
00:00:43,000 --> 00:00:50,000
And it works. Yes.

8
00:00:50,000 --> 00:00:54,000
This is a car that uses a balloon tube.

9
00:00:54,000 --> 00:01:08,000
The material that you need to build, to prepare it, are three flames.

10
00:01:08,000 --> 00:01:20,000
A thing to contain air and the balloon goes with it.

11
00:01:20,000 --> 00:01:23,000
Four wheels.

12
00:01:23,000 --> 00:01:26,000
A big metal connector.

13
00:01:26,000 --> 00:01:29,000
And two metal sticks.

14
00:01:30,000 --> 00:01:34,000
One balloon.

15
00:01:34,000 --> 00:01:38,000
Twelve stringers.

16
00:01:38,000 --> 00:01:46,000
And one trunk.

17
00:01:46,000 --> 00:01:59,000
This car uses aeolic energy, because air is a type of aeolic energy.

18
00:01:59,000 --> 00:02:12,000
To use it, you need to lower the balloon and put it on the floor.

19
00:02:12,000 --> 00:02:21,000
And then, you put it on the floor.

20
00:02:21,000 --> 00:02:25,000
Hello, we are going to present an aeolic generator.

21
00:02:25,000 --> 00:02:31,000
The materials are cables, screws and a platform.

22
00:02:31,000 --> 00:02:36,000
Batteries, spiral, wooden stick, squat and micro motor.

23
00:02:37,000 --> 00:02:40,000
First, put the wooden stick in the platform.

24
00:02:40,000 --> 00:02:43,000
Next, with the bracket, sustain the spiral in the top of the wooden stick.

25
00:02:43,000 --> 00:02:48,000
Then, put the cable in the spiral and hold the cable in the battery.

26
00:02:48,000 --> 00:02:52,000
The machine uses aeolic energy.

27
00:02:52,000 --> 00:02:59,000
The chemical energy is transformed into electrical energy.

28
00:02:59,000 --> 00:03:03,000
The electrical energy is transformed into mechanical energy.

29
00:03:03,000 --> 00:03:08,000
And the mechanical energy is transformed into aeolic energy.

30
00:03:08,000 --> 00:03:14,000
The objective of this machine is that the battery makes the spiral move.

31
00:03:14,000 --> 00:03:18,000
We didn't like too much to do this machine.

32
00:03:18,000 --> 00:03:20,000
But we are happy with the results.

33
00:03:20,000 --> 00:03:24,000
Thank you for listening. Bye-bye.

34
00:03:24,000 --> 00:03:32,000
We are going to speak about a machine that was using a balloon.

35
00:03:32,000 --> 00:03:52,000
The materials that you need are 4 wheels, 4 metal brackets, 1 large metal bracket, 2 metal bars, 1 finity, 6 screws, 1 balloon, 3 flanges and 1 piece of plastic with holes.

36
00:03:52,000 --> 00:03:56,000
It works with wind energy.

37
00:03:56,000 --> 00:04:01,000
It works by transforming the wind energy into mechanical energy.

38
00:04:01,000 --> 00:04:07,000
To make it work, you have to blow the balloon by blowing in the thingy.

39
00:04:07,000 --> 00:04:10,000
Then, you have to blow the thingy.

40
00:04:10,000 --> 00:04:15,000
Finally, you have to open the thingy and do the curve, too.

41
00:04:21,000 --> 00:04:26,000
This is an aeolic generator that generates aeolic energy.

42
00:04:26,000 --> 00:04:29,000
And we are going to show you how we've done it.

43
00:04:30,000 --> 00:04:31,000
Materials.

44
00:04:31,000 --> 00:04:46,000
A wooden stick, a screw, a battery, a tubing, a motor, 2 wires, 1 of the wires, a lever, a base and 2 brackets.

45
00:04:46,000 --> 00:04:48,000
First step.

46
00:04:48,000 --> 00:04:54,000
You have to pick the wooden stick, 4 screws and 2 brackets.

47
00:04:54,000 --> 00:04:58,000
You put the stick inside of the base.

48
00:04:58,000 --> 00:04:59,000
Second step.

49
00:04:59,000 --> 00:05:07,000
Then, we put the bracket on both sides of the stick and we screw them.

50
00:05:07,000 --> 00:05:09,000
Third step.

51
00:05:09,000 --> 00:05:19,000
We have to put the engine with a bracket and we put a screw to join it with the wooden stick.

52
00:05:19,000 --> 00:05:25,000
Then, we have to put the cable and then join it to the circuit.

53
00:05:25,000 --> 00:05:27,000
Fourth step.

54
00:05:27,000 --> 00:05:34,000
Then, we stick the battery to the base and we make a circuit and connect it with the cable.

55
00:05:44,000 --> 00:05:48,000
This is an aeolic energy generator.

56
00:05:48,000 --> 00:05:51,000
And these are the materials.

57
00:05:51,000 --> 00:06:06,000
Brackets, fan, a platform of wood, batteries and wires, a screw and a battery container, nails and a wooden stick.

58
00:06:06,000 --> 00:06:15,000
This machine uses aeolic energy but we need a battery to move the fan.

59
00:06:15,000 --> 00:06:18,000
Well, it doesn't use aeolic energy.

60
00:06:18,000 --> 00:06:27,000
It's chemical energy transformed into mechanical energy.

61
00:06:27,000 --> 00:06:29,000
This is how it works.

62
00:06:32,000 --> 00:06:45,000
We liked the result but we didn't like doing it because there were a lot of things to do and a lot of nails to screw.

63
00:06:46,000 --> 00:06:47,000
Bye.

64
00:06:47,000 --> 00:06:48,000
Bye.

65
00:06:48,000 --> 00:06:49,000
Bye.

66
00:06:49,000 --> 00:06:52,000
This car is an electric machine.

67
00:06:52,000 --> 00:07:02,000
The car converts chemical energy into electrical energy and the engines transform into kinetic energy.

68
00:07:02,000 --> 00:07:18,000
This car moves by batteries, two batteries, four wheels and an engine.

69
00:07:18,000 --> 00:07:29,000
The connection of the wires goes through the engine to the switch.

70
00:07:32,000 --> 00:07:35,000
It's like this one, the car.

71
00:07:35,000 --> 00:07:41,000
The materials are wood, plastic and metal.

72
00:07:41,000 --> 00:07:49,000
The plastic, the wheels and the disc and the circuit boards.

73
00:07:49,000 --> 00:07:52,000
We have got plastic and then the wood.

74
00:07:52,000 --> 00:08:09,000
The metal is this piece of metal, this bar of metal and the wood is this thing that holds.

75
00:08:09,000 --> 00:08:20,000
The basic things are the four wheels, the one engine and one elastic band.

76
00:08:21,000 --> 00:08:39,000
Another thing that is important on the car is this plastic circumference that holds the plastic disc for the movement.

77
00:08:39,000 --> 00:09:02,000
If you do like this, the wheels move and when the motor is connected, it's like spinning and then when it spins, only these two wheels move and then the others stop working.

78
00:09:02,000 --> 00:09:08,000
The speed of the car is approximately three kilometres per hour.

79
00:09:09,000 --> 00:09:28,000
There are two wires, one negative and one positive, that the car moves and goes to the switch.

80
00:09:29,000 --> 00:09:39,000
You can switch and then we are going to do a demonstration of the car.

81
00:09:39,000 --> 00:10:06,000
Our electric car, the materials are two batteries, four wheels, a switch, six screws of M4, six nuts of M4, two screws of M3, two nuts of M3 and a wire.

82
00:10:06,000 --> 00:10:18,000
A little motor, a motor bracket, a fleet of two centimetres, a plane skewer and a gate of six seven.

83
00:10:18,000 --> 00:10:45,000
A plastic of four centimetres, a little motor, a GM base of 8.5 per 20 centimetres, an elastic band of 6 centimetres and a metal bar of 10 per 0.4 centimetres.

84
00:10:46,000 --> 00:10:56,000
How does it work? First, the battery generates electricity. This electricity goes through two cables, the red and the black.

85
00:10:57,000 --> 00:11:12,000
It passes through the mini motor and then to the switch. The little metal stick of the mini motor moves. This causes that the small wheel moves.

86
00:11:12,000 --> 00:11:18,000
The movement of the small wheel and the big wheel causes that the car moves.

87
00:11:18,000 --> 00:11:37,000
Now, the instructions are, first you need to put the flicks in their seat by pressing them with screws and nuts of M4.

88
00:11:37,000 --> 00:11:53,000
Then you need to put the wires in the seat. Next, you put the axis of plastic in the motor.

89
00:11:53,000 --> 00:12:09,000
Then you put inside the abrasivator.

90
00:12:09,000 --> 00:12:23,000
Then you put it and you put the elastic band to roll it.

91
00:12:24,000 --> 00:12:38,000
This machine is an aeolic geometric. The materials are a cable, a battery, a light bulb and a helmet.

92
00:12:38,000 --> 00:12:48,000
What is used for? It is used to create aeolic energy.

93
00:12:48,000 --> 00:13:03,000
Hello, I am Gabriel. And I am Teruma.

94
00:13:03,000 --> 00:13:19,000
This is an aeolic generator. This machine has a battery, a light bulb and a long wire. It also has a fan.

95
00:13:19,000 --> 00:13:39,000
The chemical energy of the battery converts into electrical energy that converts into mechanical energy of the fan and the fan spins around.

96
00:13:39,000 --> 00:14:05,000
We do it with positive and negative wires to connect the machine to go.

97
00:14:05,000 --> 00:14:15,000
Hi, we are Hector, Sergio, Fabiola and me, Teruma. We are going to present you our machine. It works with aeolic energy.

98
00:14:15,000 --> 00:14:22,000
When the balloon is blown, it moves. The bag don't let blow the balloon and keep the rope.

99
00:14:22,000 --> 00:14:28,000
The objectives are very simple. Making a car that we can put in the air moves.

100
00:14:28,000 --> 00:14:35,000
Some materials are four wheels and two axes of iron.

101
00:14:35,000 --> 00:14:39,000
Aluminium and four squares of graphite.

102
00:14:39,000 --> 00:14:42,000
Six screws and six nuts.

103
00:14:42,000 --> 00:14:45,000
One for a maze and a small riddle.

104
00:14:46,000 --> 00:14:50,000
A balloon and a technique lid.

105
00:14:50,000 --> 00:14:53,000
And one big valve opens.

106
00:14:53,000 --> 00:15:09,000
When we open the bag, the air escapes very fast out of the balloon.

107
00:15:09,000 --> 00:15:18,000
The pressure that is there in the floor produces movement.

108
00:15:19,000 --> 00:15:23,000
And now we are going to make an illustration because our balloon is broken.

109
00:15:23,000 --> 00:15:25,000
So, to look up.
