Hello boys and girls! Today we are going to talk about the properties of materials.

1
00:00:08,000 --> 00:00:16,000
Materials have different properties. This means they look and feel different.

2
00:00:16,000 --> 00:00:29,000
Materials can be soft, like for example a pillow, or hard, like for example a nail.

3
00:00:30,000 --> 00:00:43,000
As well, they can be rough, like for example the trunk of a tree, or smooth, like some stones.

4
00:00:45,000 --> 00:00:57,000
Materials can also be rigid, like a pan, or flexible, like these flip flops.

5
00:00:59,000 --> 00:01:13,000
Another property of materials is to be transparent, like for example a glass of a window, or opaque, like a paperboard.

6
00:01:13,000 --> 00:01:29,000
Finally, we can also say that materials can be waterproof, like an umbrella, or absorbent, like a sponge.
