00:00:00,240 --> 00:00:09,779
Good morning, boys and girls. How are you today? I hope that everyone is okay and ready for a new natural science class.

2
00:00:10,039 --> 00:00:13,539
So today we are going to talk about water.

3
00:00:14,119 --> 00:00:19,059
So if you have your book, you can open your book on page 8 and 9.

4
00:00:19,600 --> 00:00:29,579
And if you are going to use the digital version of the book, you can open this book on pages 80 and 81.

5
00:00:29,579 --> 00:00:39,759
okay so let's going to talk about water as i said water is an example of matter and water has

6
00:00:39,759 --> 00:00:48,140
three main characteristics so let's going to see the characteristics so water is odorless

7
00:00:48,140 --> 00:00:58,460
tasteless and colorless oh these words are very difficult and new for us so let's going to explain

8
00:00:58,460 --> 00:01:06,739
these words little by little and step by step. The first one, OTHERLESS. Let's go

9
00:01:06,739 --> 00:01:16,400
to see the meaning of OTHERLESS. OTHERLESS means no smell. So if you take a

10
00:01:16,400 --> 00:01:25,040
glass of water and you smell this glass of water you can see that there is no

11
00:01:25,040 --> 00:01:37,859
smell so water is odorless ok so no smell if you have also in the kitchen the

12
00:01:37,859 --> 00:01:44,180
possibility to smell a glass of orange juice you can see the difference so

13
00:01:44,180 --> 00:01:49,400
please if you can take a glass of water and a glass of orange juice you can see

14
00:01:49,400 --> 00:01:59,340
the difference right now let's going to analyze the second word tasteless so tasteless is means

15
00:01:59,340 --> 00:02:07,780
no taste so if you have your glass of water and you drink a little bit of this water you can see

16
00:02:07,780 --> 00:02:17,680
that it's no or you can feel that it's not salty or it's not sweet so the taste is nothing so no

17
00:02:17,680 --> 00:02:26,759
taste for water and if you have your glass of orange juice for example you can see that this

18
00:02:26,759 --> 00:02:37,639
the taste is orange so the taste the taste is different between the orange juice and water

19
00:02:37,639 --> 00:02:46,020
and finally colorless maybe is the easiest word so means no color so as you can see

20
00:02:46,020 --> 00:02:55,240
if you have your glass of water it's transparent it's no color on it and if you see the glass of

21
00:02:55,240 --> 00:03:04,860
orange juice obviously it's orange so as a review as a quick review the three main characteristics

22
00:03:04,860 --> 00:03:16,620
of water are odorless tasteless and colorless okay so it's going to continue and

23
00:03:16,620 --> 00:03:25,840
we can find water in the three states of matter so this means we can find water

24
00:03:25,840 --> 00:03:34,680
solid solid water we can find liquid water and we can find gas water okay even in at home

25
00:03:34,680 --> 00:03:43,280
it is easy to find the three states of water. So let's going to see the main characteristics of

26
00:03:43,280 --> 00:03:55,560
water is in a gas state at temperatures over 100 degrees. This means that the temperature is more

27
00:03:55,560 --> 00:04:04,960
than 100 okay over the word the word over means more than 100 okay so imagine if you are helping

28
00:04:04,960 --> 00:04:14,180
in the cook in the kitchen and you put some water on the fire and you can see some vapor

29
00:04:14,180 --> 00:04:23,680
is because this water is over 100 degree so this water is getting into gas okay

30
00:04:25,560 --> 00:04:32,019
Next, so water is in a liquid state between 1 degree and 99 degrees.

31
00:04:32,019 --> 00:04:37,220
OK, so this is the most common state of water.

32
00:04:37,439 --> 00:04:40,939
So if you open the tap, you can find liquid water.

33
00:04:41,439 --> 00:04:49,379
OK, and finally, water is in a solid state at temperatures below zero degrees.

34
00:04:49,660 --> 00:04:53,060
So below means less than zero.

35
00:04:53,060 --> 00:05:01,959
So if you put some water into your freeze in the kitchen, you can have solid water.
