Hi, we are Pablo, Mateo and Lolo. Today we will be sharing information about our machines with you. As you know, our machines need energy to work. In our case, our machines use energy from people.

2
00:00:39,340 --> 00:00:43,340
There are two types of machines.

3
00:00:43,340 --> 00:00:51,340
Simple machines that have one or two parts.

4
00:00:51,340 --> 00:01:00,030
And complex machines that have more than two parts.

5
00:01:00,030 --> 00:01:07,030
And combinations of other machines.

6
00:01:07,030 --> 00:01:12,030
Our machine is a simple machine.

7
00:01:12,030 --> 00:01:17,030
First, a cardboard tower.

8
00:01:17,030 --> 00:01:22,030
Second, a pulley.

9
00:01:22,030 --> 00:01:26,030
Third, a rope.

10
00:01:26,030 --> 00:01:28,030
And finally, an axe.

11
00:01:28,030 --> 00:01:58,069
And now, we will show the machine in action.

12
00:01:58,069 --> 00:01:59,250
Thank you for listening.

13
00:01:59,609 --> 00:02:00,209
Bye-bye.
