Hi, we are Alonso, Jorge, Jaime, Alejandro and Daniel.

1
00:00:17,000 --> 00:00:26,000
Today we will be sharing information about our machine with you.

2
00:00:26,000 --> 00:00:31,000
As you know, all machines need energy.

3
00:00:31,000 --> 00:00:39,000
To work, in our case, it uses chemical energy.

4
00:00:39,000 --> 00:00:43,000
There are two types of machines.

5
00:00:43,000 --> 00:00:49,000
Simple machines that have one or two parts

6
00:00:49,000 --> 00:00:57,000
and complex machines that have more than two parts.

7
00:00:57,000 --> 00:01:01,000
Our machine is a complex machine.

8
00:01:01,000 --> 00:01:09,000
Now we will explain the parts of our machine.

9
00:01:09,000 --> 00:01:15,000
First, the base is made of iron.

10
00:01:15,000 --> 00:01:20,000
The walls and bars are made of carbon.

11
00:01:20,000 --> 00:01:28,000
Second, the vents are made of clay and gaseous material.

12
00:01:28,000 --> 00:01:38,000
When we exhaust the gas, it turns into energy sources.

13
00:01:38,000 --> 00:01:43,000
Finally, the chemical reaction moves the machine.

14
00:02:46,000 --> 00:02:56,000
We think our machine didn't work because it needs more energy.

15
00:02:56,000 --> 00:02:59,000
Bye bye!
