00:00:00,000 --> 00:00:08,080
Hi kids and welcome to our natural science lesson.

2
00:00:08,080 --> 00:00:18,160
Today we are going to learn about conductors and insulators.

3
00:00:18,160 --> 00:00:25,640
We use different energy sources like solar energy, wind energy and petrol to produce

4
00:00:25,640 --> 00:00:26,640
electricity.

5
00:00:26,640 --> 00:00:36,480
But how does electricity travel from its origin to our homes?

6
00:00:36,480 --> 00:00:40,280
Let's see.

7
00:00:40,280 --> 00:00:44,800
Electricity is produced at power stations.

8
00:00:44,800 --> 00:00:52,800
From power stations, electricity travels along power lines with pylons.

9
00:00:52,800 --> 00:00:56,320
Electricity flows through cables in streets.

10
00:00:56,320 --> 00:01:03,280
And finally, electricity arrives to the electrical sockets in our homes.

11
00:01:03,280 --> 00:01:09,920
And to carry electricity, there are two types of materials that we have to take into account,

12
00:01:09,920 --> 00:01:12,040
conductors and insulators.

13
00:01:12,040 --> 00:01:14,800
Let's see them.

14
00:01:14,800 --> 00:01:22,360
On the one hand, we have electrical conductors, in Spanish, conductores eléctricos, which

15
00:01:22,360 --> 00:01:28,320
are the materials through which electricity flows very easily.

16
00:01:28,320 --> 00:01:35,940
Examples of electrical conductors are copper, steel and seawater.

17
00:01:35,940 --> 00:01:43,080
On the other hand, electrical insulators, in Spanish, aislantes eléctricos, which are

18
00:01:43,080 --> 00:01:48,800
the materials through which electricity doesn't flow.

19
00:01:48,800 --> 00:01:56,920
Examples of electrical insulators are plastic, wood and glass.

20
00:01:56,920 --> 00:02:03,360
There is also another type of conductors and insulators, thermal conductors and thermal

21
00:02:03,360 --> 00:02:05,560
insulators.

22
00:02:05,560 --> 00:02:12,480
Thermal conductors transfer heat very easily, for example, metals.

23
00:02:12,480 --> 00:02:17,760
That's why it is very dangerous to touch a metal saucepan when we are boiling water,

24
00:02:17,760 --> 00:02:24,160
because metal transfers the heat and we can hurt our skin.

25
00:02:24,160 --> 00:02:32,960
Thermal insulators don't transfer heat easily, for example, plastics and wood.

26
00:02:32,960 --> 00:02:34,320
And here is the end.

27
00:02:34,320 --> 00:02:35,880
I hope you like it.

28
00:02:35,880 --> 00:02:36,880
See you!

29
00:02:36,880 --> 00:02:38,720
Lots of kisses!
