Hello everyone. Today we are going to talk about where do materials come from. Let's

1
00:00:10,000 --> 00:00:25,000
see. Natural materials come from the ground or from living things. Natural materials come

2
00:00:25,000 --> 00:00:39,000
from the ground or from the living things. Class, mirror, word. Natural materials come

3
00:00:39,000 --> 00:00:54,000
from the ground or from living things. Excellent, everybody. Let's see what's next. Now, these

4
00:00:54,000 --> 00:01:13,000
are the materials that come from the ground. Sand, rocks, and petroleum. These are the

5
00:01:13,000 --> 00:01:33,000
materials that come from the ground. Sand, rocks, and petroleum. Class, mirror, word.

6
00:01:33,000 --> 00:01:56,000
Materials from the ground. Sand, rocks, and petroleum. Excellent, everybody. Well done.

7
00:01:56,000 --> 00:02:13,000
Now let's see what's next. These are the materials that come from living things. Wool, wood,

8
00:02:13,000 --> 00:02:43,000
and cotton. Class, mirror, word. Materials from living things. Wool, wood, and cotton.

9
00:02:43,000 --> 00:02:51,000
Good. Well done, everybody. Now, these are the natural materials that come from ground

10
00:02:51,000 --> 00:03:00,000
and from living things. Let's see if you remember. Is the wood from the ground or from

11
00:03:00,000 --> 00:03:11,000
living things? It's from the living things, from the trees. How about the cotton? Where

12
00:03:11,000 --> 00:03:21,000
is the cotton from? Is it from the ground or from living things? It's from living things,

13
00:03:21,000 --> 00:03:36,000
from some plant. And how about the sand? Where does the sand come from? Comes from the ground.

14
00:03:36,000 --> 00:03:47,000
How about the wool? Where does the wool come from? It comes from the living things, animals

15
00:03:47,000 --> 00:04:01,000
like sheep. And how about the petroleum? The petroleum comes from the ground. And the rocks

16
00:04:01,000 --> 00:04:14,000
comes from the ground. Excellent, everybody. Now, welcome to the factory. In the factory,

17
00:04:14,000 --> 00:04:39,000
we transform natural materials to manufactured materials. Class, mirror, word. In the factory,

18
00:04:39,000 --> 00:04:59,000
we transform natural materials to manufactured materials. Very good. Excellent, everybody.

19
00:04:59,000 --> 00:05:23,000
Now, the manufactured materials are metal, paper, fabric. This is a fabric. And glass.

20
00:05:23,000 --> 00:05:37,000
We use natural materials to make manufactured materials. These are the natural materials

21
00:05:37,000 --> 00:05:51,000
to make manufactured materials. The petroleum, the sand, again, the rocks, the wood, the

22
00:05:51,000 --> 00:06:09,000
wool, and the cotton. These all make some metal, paper, fabric, and glass. Now, let's

23
00:06:09,000 --> 00:06:31,000
see the manufactured materials. Metal, paper, fabric, glass, and plastic. Now, what are

24
00:06:31,000 --> 00:06:38,000
the natural materials we use for these manufactured materials? Let's see. Number one, petroleum.

25
00:06:39,000 --> 00:06:51,000
Where does it go with? Let's see. Petroleum is used to make plastics. Petroleum makes

26
00:06:52,000 --> 00:07:12,000
plastics. Number two, the sand. Sand makes glass. Number three, rocks. Rocks make metals.

27
00:07:12,000 --> 00:07:25,000
Ding, ding. How about the wood? What does it make? Let's see. Wood makes paper. Paper.

28
00:07:27,000 --> 00:07:38,000
And how about the wool? What does it make? The wool makes fabric, like this.

29
00:07:39,000 --> 00:07:46,000
And how about the cotton? How about the cotton? What does it make? The cotton is used for

30
00:07:49,000 --> 00:07:53,000
fabric as well. Well done, everybody.
