That is our project. We make a robot that is called Marcel3 with Marcos and Sergio. 00:00:01
We made it with aluminium paper, we cover the robot and we make it also with colour transparent paper 00:00:07
because later when we put on the light, the light will be the colour of the paper. 00:00:18
Now Marcos is going to explain how we make the circuit. 00:00:26
It has three generators inside with cable goes to the bottom and connect to the nine lines. 00:00:30
Also the cable goes to the head and join to another line. 00:00:42
Now I am going to explain how are the parts of the electrical circuit. 00:00:52
The generator is a machine that transforms chemical energy into light. 00:00:57
Later we made one switch here and another in the head. 00:01:06
A switch is an object that we use to open or close the circuit. 00:01:12
Then we use some light bulbs that transform electricity into light. 00:01:19
and this is our project. 00:01:24
And it has a bar with wheels that has an electronic motor 00:01:30
with arm chips that come... 00:01:37
This is a football field 00:01:45
and I make it to play 00:01:48
And here is the generator connected to two cables that travel to the switch and to the light bulb. 00:01:52
The generator transforms the electrical energy into electricity, the switch makes that the electricity travels to the light bulb. 00:02:11
When it is opening, it travels so fast and the lightbar travels with it. 00:02:32
This is our project. Lucia now is going to explain us how it works. 00:02:49
This is an example that we do to explain it. 00:02:56
It has its cable, negative and positive, in group of three light bulbs. 00:03:12
This is the negative and this is the positive. 00:03:19
If we connect the negative with the negative and the positive with the positive, it is function. 00:03:23
This happens when we put on and the generator passes all the energy into electricity 00:03:38
and this electricity go around the cables and good function the light. 00:03:51
I am going to show you how we can do electricity with potatoes and lemon. 00:04:01
First we need three potatoes and one lemon. 00:04:09
We have to cut in the middle and make two holes in each lemon and potato. 00:04:12
We put a coin inside one hole of each potato and we do the same with the screw. 00:04:18
Later we connect it with cables and the electricity is going to vacuum because the coins have copper and the screws have tin. 00:04:25
And with the juice of the potatoes and the lemon, it gives electricity. 00:04:36
And if we shoot, it can see that more or less it's electricity. 00:04:40
I do a hotel that have two lights here near the doors and in the top of the hotel. 00:04:46
I have a motor that we connect the negative with the positive and the positive with the negative 00:05:00
And because of that, we know that the lights have to be turned on, and this is so. 00:05:18
My present is a house of the electrical circuit. 00:05:31
The cables are in the walls inside the house, and we have two walls inside, 00:05:35
and the motor that is like a type of, I don't know, a chimney or like this. 00:05:41
We play with the switch and when it's on, the light fangs and this hope is not fanged. 00:05:49
And this is all. 00:05:58
We are going to present our project. 00:06:01
Our project is about one city that has electricity, and here we can find some cables that are connected to the motor. 00:06:04
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. 00:06:18
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. 00:06:31
that it has two parts, so when you connect it to the second part, it functions, and if you misconnect it, it also functions. 00:06:59
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. 00:07:43
Hello, hello, this is our project. It's an electrical system. 00:07:57
This project works with a battery, a cable, two threads and three light bulbs. 00:08:03
First the battery has two charges, positive and negative. 00:08:18
The electricity starts here and all the cables join here. 00:08:26
Then it continues and when you press this button, these two cables join and the electricity comes to here. 00:08:32
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. 00:08:41
and now they have energy and this one, so it starts again and again and this is it. 00:08:56
For this project we did a city with street lamps that are the light bulbs 00:09:07
and here we have the electrical circuit. 00:09:14
We use 20 cables for each lightbulb and we need a switch and a generator and a timer to get closer the cables. 00:09:19
What we did is that each lightbulb has a positive cable and a negative one. 00:09:38
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. 00:09:43
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. 00:09:57
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. 00:10:24
This is my project and here I do like a street, here is a generator behind the house and here 00:10:49
are three bulbs for the cars and one for illuminate it and here is the switches that they do like 00:11:04
The light of the car goes and the light of the street light. 00:11:18
And here I have the cables, all together I have the positive ones and the negative ones. 00:11:30
And here behind I have the generator, behind the house for two canals and that's all. 00:11:42
I prepare electrical system that we see that the solar water can conduct electricity. 00:11:55
I have two rods, but when you put them together the light bulb turns on. 00:12:11
I have the battery and the positive and negative cables. 00:12:21
When you put them in water separately, nothing happens. 00:12:29
but it is good that we bring them to our cell in such a way that if we switch on, 00:12:36
we don't put them to bed. 00:12:54
And when you put water on, the light bulb will switch on quickly and with more intense. 00:13:01
The other project that we have is an electric car. 00:13:11
I put a battery connected with a switch in the middle and a propeller 00:13:18
which is going to turn with the motor. 00:13:27
When you switch on, the car will be influenced with a force that will make it work. 00:13:32
And that is our problem. 00:13:48
I do an electric circuit that is the generator, the switch, and the cables, and if you put on the switch, the refrigerator will... 00:13:52
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. 00:14:15
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. 00:14:43
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. 00:15:03
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. 00:15:23
Hello, today I am going to present a small experiment of electrical circuit. 00:15:40
First you have to put the two cables, you have to separate them, like this. 00:15:54
And each cable you have to put in each hole of the battery. 00:16:01
Then if you want you can put a little bit of cello to make the cable fall down. 00:16:06
Then the cable you have to connect it to the switch. 00:16:15
And the last you have to connect it to the light bulb. 00:16:20
And that's all. 00:16:28
Hi, today I'm going to talk about electric circuits. 00:16:32
You need two batteries, a silver tape, aluminum, and a blue cable. 00:16:37
First, you join the two batteries, the positive and the negative, 00:16:47
and you put the brown one into the positive one, and the negative, the blue one. 00:16:52
And you put the brown cable into the light, and when you connect it, the same thing will happen. 00:17:02
I did a football shirt. I brought the player. Here is the film. Here is the light bulb. 00:17:20
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. 00:17:40
