1
00:00:01,010 --> 00:00:07,009
That is our project. We make a robot that is called Marcel3 with Marcos and Sergio.

2
00:00:07,009 --> 00:00:18,010
We made it with aluminium paper, we cover the robot and we make it also with colour transparent paper

3
00:00:18,010 --> 00:00:26,010
because later when we put on the light, the light will be the colour of the paper.

4
00:00:26,010 --> 00:00:30,010
Now Marcos is going to explain how we make the circuit.

5
00:00:30,010 --> 00:00:42,009
It has three generators inside with cable goes to the bottom and connect to the nine lines.

6
00:00:42,009 --> 00:00:52,450
Also the cable goes to the head and join to another line.

7
00:00:52,450 --> 00:00:57,450
Now I am going to explain how are the parts of the electrical circuit.

8
00:00:57,450 --> 00:01:06,450
The generator is a machine that transforms chemical energy into light.

9
00:01:06,450 --> 00:01:12,450
Later we made one switch here and another in the head.

10
00:01:12,450 --> 00:01:19,450
A switch is an object that we use to open or close the circuit.

11
00:01:19,450 --> 00:01:24,450
Then we use some light bulbs that transform electricity into light.

12
00:01:24,450 --> 00:01:27,450
and this is our project.

13
00:01:30,450 --> 00:01:37,450
And it has a bar with wheels that has an electronic motor

14
00:01:37,450 --> 00:01:40,450
with arm chips that come...

15
00:01:45,450 --> 00:01:48,450
This is a football field

16
00:01:48,450 --> 00:01:52,450
and I make it to play

17
00:01:52,450 --> 00:02:11,449
And here is the generator connected to two cables that travel to the switch and to the light bulb.

18
00:02:11,449 --> 00:02:32,449
The generator transforms the electrical energy into electricity, the switch makes that the electricity travels to the light bulb.

19
00:02:32,449 --> 00:02:42,449
When it is opening, it travels so fast and the lightbar travels with it.

20
00:02:49,659 --> 00:02:56,659
This is our project. Lucia now is going to explain us how it works.

21
00:02:56,659 --> 00:03:12,150
This is an example that we do to explain it.

22
00:03:12,150 --> 00:03:19,150
It has its cable, negative and positive, in group of three light bulbs.

23
00:03:19,150 --> 00:03:23,150
This is the negative and this is the positive.

24
00:03:23,150 --> 00:03:38,310
If we connect the negative with the negative and the positive with the positive, it is function.

25
00:03:38,310 --> 00:03:51,310
This happens when we put on and the generator passes all the energy into electricity

26
00:03:51,310 --> 00:04:01,310
and this electricity go around the cables and good function the light.

27
00:04:01,310 --> 00:04:09,310
I am going to show you how we can do electricity with potatoes and lemon.

28
00:04:09,310 --> 00:04:12,310
First we need three potatoes and one lemon.

29
00:04:12,310 --> 00:04:18,310
We have to cut in the middle and make two holes in each lemon and potato.

30
00:04:18,310 --> 00:04:25,310
We put a coin inside one hole of each potato and we do the same with the screw.

31
00:04:25,310 --> 00:04:36,310
Later we connect it with cables and the electricity is going to vacuum because the coins have copper and the screws have tin.

32
00:04:36,310 --> 00:04:40,310
And with the juice of the potatoes and the lemon, it gives electricity.

33
00:04:40,310 --> 00:04:46,310
And if we shoot, it can see that more or less it's electricity.

34
00:04:46,310 --> 00:05:00,310
I do a hotel that have two lights here near the doors and in the top of the hotel.

35
00:05:00,310 --> 00:05:18,290
I have a motor that we connect the negative with the positive and the positive with the negative

36
00:05:18,290 --> 00:05:29,290
And because of that, we know that the lights have to be turned on, and this is so.

37
00:05:31,290 --> 00:05:35,290
My present is a house of the electrical circuit.

38
00:05:35,290 --> 00:05:41,290
The cables are in the walls inside the house, and we have two walls inside,

39
00:05:41,290 --> 00:05:49,290
and the motor that is like a type of, I don't know, a chimney or like this.

40
00:05:49,290 --> 00:05:58,290
We play with the switch and when it's on, the light fangs and this hope is not fanged.

41
00:05:58,290 --> 00:06:00,290
And this is all.

42
00:06:01,290 --> 00:06:04,290
We are going to present our project.

43
00:06:04,290 --> 00:06:18,290
Our project is about one city that has electricity, and here we can find some cables that are connected to the motor.

44
00:06:18,290 --> 00:06:31,290
The cables pass through the house and under this, and we put in the motor, and we break the motor, and it dies, and it's sold.

45
00:06:31,290 --> 00:06:59,730
This is my project. It is an electrical circuit. First I run the things, then I put the generator with the cables so they can pass the negative and the positive charges through the switching and through the switch to the valve.

46
00:06:59,730 --> 00:07:43,620
that it has two parts, so when you connect it to the second part, it functions, and if you misconnect it, it also functions.

47
00:07:43,620 --> 00:07:56,620
This is because the negative charges pass through the cable to the valve, but if you put the switch on, it doesn't pass, so, happy on that, this is it.

48
00:07:57,620 --> 00:08:03,620
Hello, hello, this is our project. It's an electrical system.

49
00:08:03,620 --> 00:08:18,620
This project works with a battery, a cable, two threads and three light bulbs.

50
00:08:18,620 --> 00:08:26,620
First the battery has two charges, positive and negative.

51
00:08:26,620 --> 00:08:32,620
The electricity starts here and all the cables join here.

52
00:08:32,620 --> 00:08:41,620
Then it continues and when you press this button, these two cables join and the electricity comes to here.

53
00:08:41,620 --> 00:08:56,620
There is a few energy so we have another switch here because we need to pass the energy from here to the tube like that.

54
00:08:56,620 --> 00:09:07,620
and now they have energy and this one, so it starts again and again and this is it.

55
00:09:07,620 --> 00:09:14,620
For this project we did a city with street lamps that are the light bulbs

56
00:09:14,620 --> 00:09:19,620
and here we have the electrical circuit.

57
00:09:19,620 --> 00:09:38,620
We use 20 cables for each lightbulb and we need a switch and a generator and a timer to get closer the cables.

58
00:09:38,620 --> 00:09:43,620
What we did is that each lightbulb has a positive cable and a negative one.

59
00:09:43,620 --> 00:09:57,620
So we put a red cable and a blue one and later we connect all the red together and all the red together inside the clema that goes inside the switch and later there is a blue one.

60
00:09:57,620 --> 00:10:24,340
That is, the light bulbs have to charge the positive and the negative. We know that because the positive is longer than the negative and the generator has to charge it. The longer is the negative and the shorter is the positive.

61
00:10:24,340 --> 00:10:49,940
So what happens is that when this is closed, the electricity doesn't pass to the light bulbs, which are the street lamps, so it doesn't work. But when we switch on the switch, it works and the light works.

62
00:10:49,940 --> 00:11:04,559
This is my project and here I do like a street, here is a generator behind the house and here

63
00:11:04,559 --> 00:11:18,299
are three bulbs for the cars and one for illuminate it and here is the switches that they do like

64
00:11:18,299 --> 00:11:30,870
The light of the car goes and the light of the street light.

65
00:11:30,870 --> 00:11:42,870
And here I have the cables, all together I have the positive ones and the negative ones.

66
00:11:42,870 --> 00:11:52,870
And here behind I have the generator, behind the house for two canals and that's all.

67
00:11:55,500 --> 00:12:11,500
I prepare electrical system that we see that the solar water can conduct electricity.

68
00:12:11,500 --> 00:12:21,500
I have two rods, but when you put them together the light bulb turns on.

69
00:12:21,500 --> 00:12:29,500
I have the battery and the positive and negative cables.

70
00:12:29,500 --> 00:12:36,500
When you put them in water separately, nothing happens.

71
00:12:36,500 --> 00:12:54,330
but it is good that we bring them to our cell in such a way that if we switch on,

72
00:12:54,330 --> 00:13:01,690
we don't put them to bed.

73
00:13:01,690 --> 00:13:11,690
And when you put water on, the light bulb will switch on quickly and with more intense.

74
00:13:11,690 --> 00:13:18,690
The other project that we have is an electric car.

75
00:13:18,690 --> 00:13:27,690
I put a battery connected with a switch in the middle and a propeller

76
00:13:27,690 --> 00:13:32,690
which is going to turn with the motor.

77
00:13:32,690 --> 00:13:48,690
When you switch on, the car will be influenced with a force that will make it work.

78
00:13:48,690 --> 00:13:52,690
And that is our problem.

79
00:13:52,690 --> 00:14:15,690
I do an electric circuit that is the generator, the switch, and the cables, and if you put on the switch, the refrigerator will...

80
00:14:15,690 --> 00:14:43,870
For my project I do a lighthouse that is an electrical circuit that is composed by two cables, one negative and one positive, a generator, a switch and a light bulb.

81
00:14:43,870 --> 00:15:03,870
When we connect the cable to the generator, the energy passes through them, and with the switch, the light goes on, and this is it.

82
00:15:03,870 --> 00:15:23,470
I made a windmill that functions with a movement. I put the chemicals under the wood and then I connected them with the motor that is here.

83
00:15:23,470 --> 00:15:40,769
Then I put the generator inside the box and I put at the front a switch and you switch it on and you see that it moves.

84
00:15:40,769 --> 00:15:54,600
Hello, today I am going to present a small experiment of electrical circuit.

85
00:15:54,600 --> 00:16:01,600
First you have to put the two cables, you have to separate them, like this.

86
00:16:01,600 --> 00:16:06,600
And each cable you have to put in each hole of the battery.

87
00:16:06,600 --> 00:16:15,600
Then if you want you can put a little bit of cello to make the cable fall down.

88
00:16:15,600 --> 00:16:20,600
Then the cable you have to connect it to the switch.

89
00:16:20,600 --> 00:16:25,600
And the last you have to connect it to the light bulb.

90
00:16:28,600 --> 00:16:32,610
And that's all.

91
00:16:32,610 --> 00:16:36,850
Hi, today I'm going to talk about electric circuits.

92
00:16:37,570 --> 00:16:46,750
You need two batteries, a silver tape, aluminum, and a blue cable.

93
00:16:47,450 --> 00:16:52,590
First, you join the two batteries, the positive and the negative,

94
00:16:52,590 --> 00:17:02,590
and you put the brown one into the positive one, and the negative, the blue one.

95
00:17:02,590 --> 00:17:20,900
And you put the brown cable into the light, and when you connect it, the same thing will happen.

96
00:17:20,900 --> 00:17:40,900
I did a football shirt. I brought the player. Here is the film. Here is the light bulb.

97
00:17:40,900 --> 00:18:01,220
We need a light bulb, a switcher, two cables and the battery that is going to send the energy to the light bulb and it is going to illuminate.
