1
00:00:01,389 --> 00:00:03,509
Good morning, guys. How are you?

2
00:00:04,549 --> 00:00:07,250
First of all, I hope you are all in good health.

3
00:00:07,690 --> 00:00:12,509
If someone doesn't feel well, please let me know and take a break.

4
00:00:12,990 --> 00:00:15,990
The first thing now and the most important thing is your health

5
00:00:15,990 --> 00:00:19,670
and you will have time to work when you feel better, okay?

6
00:00:20,289 --> 00:00:24,089
Today we're going to revise the classification of living organisms

7
00:00:24,089 --> 00:00:26,730
and how are species named.

8
00:00:26,949 --> 00:00:30,010
I'm on page 16 and 17, yeah?

9
00:00:30,010 --> 00:00:38,770
Yes, we're going to revise the most important ideas about the classification of living organisms

10
00:00:38,770 --> 00:00:41,369
that you can read here.

11
00:00:41,369 --> 00:00:46,450
Taxonomies classify organisms into smaller categories according to similarities and there

12
00:00:46,450 --> 00:00:53,689
are seven categories, kingdoms, virulence, class, order, family, genus and species.

13
00:00:53,689 --> 00:00:56,770
You have to know what is a species.

14
00:00:56,770 --> 00:01:04,790
A species is a group of organisms that can reproduce in nature and produce fertile offspring.

15
00:01:05,209 --> 00:01:06,010
This is important.

16
00:01:06,269 --> 00:01:10,650
They can reproduce and they produce fertile offspring.

17
00:01:10,650 --> 00:01:19,790
OK, you had to investigate about the wolf and you had to write the name of the categories in your notebook.

18
00:01:20,170 --> 00:01:23,010
Did you all complete the information?

19
00:01:24,290 --> 00:01:24,549
Yeah.

20
00:01:24,950 --> 00:01:26,590
So here you can check.

21
00:01:26,769 --> 00:01:46,329
The seven categories are in this picture, kingdom, animalia, phylum, caudate, class mammals, order carnivore, family, canidae, genus, canis, and the name of the species, lupus.

22
00:01:46,969 --> 00:01:47,609
Very good.

23
00:01:48,049 --> 00:01:51,370
And now I'm on page 17, okay?

24
00:01:52,069 --> 00:01:54,010
We're going to listen to the audio.

25
00:01:54,010 --> 00:01:57,170
How are species named?

26
00:01:58,370 --> 00:02:01,590
Every language has its own way of naming different species.

27
00:02:02,489 --> 00:02:05,390
We call these words the common names of the species.

28
00:02:06,489 --> 00:02:10,030
Every species also has a scientific name.

29
00:02:11,129 --> 00:02:18,849
The scientific name is based on a system invented by a Swedish scientist, Carl Linnaeus, in the 18th century.

30
00:02:18,849 --> 00:02:22,430
He invented a binominal way of naming the species.

31
00:02:22,430 --> 00:02:30,789
this means that the species name is formed of two words he used latin or greek words to name

32
00:02:30,789 --> 00:02:37,389
the species the first word is the name of the genus it is always written with a capital letter

33
00:02:37,389 --> 00:02:45,129
to start the word the second word is the name of the species it is always written with a small

34
00:02:45,129 --> 00:02:55,060
letter to start the word okay i cannot clean the market but the most important idea is here

35
00:02:55,060 --> 00:03:02,580
what you should underline is um that there are two different ways we can name species

36
00:03:02,580 --> 00:03:11,300
the common name and the specific name okay the specific name is form of two words

37
00:03:11,300 --> 00:03:18,620
Latin or green words yeah here with this mind map sorry you can see the most

38
00:03:18,620 --> 00:03:26,719
important ideas how are species named with a common name like dog cat perro

39
00:03:26,719 --> 00:03:32,000
gato chicken in different language different names and the scientific name

40
00:03:32,000 --> 00:03:38,900
that is made up of two words can be Latin or Greek word okay the first word

41
00:03:38,900 --> 00:03:45,400
is the genus with a capital letter and the second one the name of the species.

42
00:03:45,400 --> 00:03:53,360
Species, is that clear? Yeah? You can practice with activity number 11. We're

43
00:03:53,360 --> 00:03:59,539
going to try to do it quickly. It says map the scientific names to the picture A to

44
00:03:59,539 --> 00:04:17,600
E? Try to guess. Try to guess. Do you know? Bostaurus. Try to match with the letter. A,

45
00:04:17,680 --> 00:04:29,199
B, C, D or E? Bostaurus, letter A. Well done. Pavocristatus, letter C. Cercucilex, is a

46
00:04:29,199 --> 00:04:40,139
tree? Yes, letter E. What about the lumbricus terrestris? The worm? Very good, letter D.

47
00:04:41,139 --> 00:04:51,959
And lynx by dinos? Very good, letter V. Well done. Now, I recommend you read again page

48
00:04:51,959 --> 00:05:04,000
17 okay and also you can have a look at page 18 yeah it's about how can we study nature they say

49
00:05:04,000 --> 00:05:10,579
that the most important thing is the observation yeah and you can use also some in some instruments

50
00:05:10,579 --> 00:05:18,000
some tools like cameras a magnifying glass a notebook yeah different things and when you

51
00:05:18,000 --> 00:05:27,279
finished reading these pages open here is written page 18 but you have to work on page 19 now

52
00:05:28,319 --> 00:05:37,120
i want you practice with activity number one and two as every day you have to copy the table you

53
00:05:37,120 --> 00:05:43,040
have to copy everything the statement the questions with your pen and you answer with

54
00:05:43,040 --> 00:05:50,000
your pencil okay and we will take a both activities next Friday okay this is the

55
00:05:50,000 --> 00:05:55,339
end of the lesson if you have any doubt any question you can send me a message

56
00:05:55,339 --> 00:06:03,779
or use the using the chat and I can't and I will try to help you okay see you

57
00:06:03,779 --> 00:06:08,420
next see you tomorrow I hope bye bye
