1
00:00:01,780 --> 00:00:09,820
Good morning guys, so today we are going to correct the activities of natural sciences on page 36

2
00:00:09,820 --> 00:00:13,160
I asked you to do exercises 1, 2 and 3

3
00:00:13,160 --> 00:00:17,820
But first we are going to listen to the text because here I have the listening

4
00:00:17,820 --> 00:00:24,839
I'm going to explain it a little bit and then we will correct the activities. Okay, let's start

5
00:00:24,839 --> 00:00:27,620
Page 37

6
00:00:27,620 --> 00:00:37,520
there are physical differences between male and female bodies these differences are called sex

7
00:00:37,520 --> 00:00:45,500
characteristics okay this unit we are going to study about reproduction and here we can read

8
00:00:45,500 --> 00:00:53,659
we can listen that we have well our bodies are different it's not the same the body of a boy

9
00:00:53,659 --> 00:00:57,740
than the body of a girl and there are because there are some differences

10
00:00:57,740 --> 00:01:03,420
between our bodies and these differences are called sex characteristics

11
00:01:03,420 --> 00:01:08,000
características sexuales the sex characteristics are the differences

12
00:01:08,000 --> 00:01:13,299
between the male body and the female body el cuerpo masculino y el cuerpo

13
00:01:13,299 --> 00:01:17,659
femenino el cuerpo de los hombres y el cuerpo de las mujeres ok the differences

14
00:01:17,659 --> 00:01:22,579
between our bodies are called sex characteristics and we have two types of

15
00:01:22,579 --> 00:01:28,040
sex characteristics, we have the primary and the secondary. The primary sex

16
00:01:28,040 --> 00:01:33,060
characteristics and the secondary sex characteristics, the primary differences

17
00:01:33,060 --> 00:01:38,120
and the secondary differences. Let's continue.

18
00:01:38,120 --> 00:01:43,719
primary sex characteristics are the physical differences between the male

19
00:01:43,719 --> 00:01:50,900
and female reproductive organs. Okay so the primary sex characteristics are the

20
00:01:50,900 --> 00:01:57,140
differences between our reproductive organ. Reproductive organ in Spanish es

21
00:01:57,140 --> 00:02:02,959
órgano reproductor. So the differences between our reproductive organs are the

22
00:02:02,959 --> 00:02:08,719
primary sex characteristics. Reproductive organs are the penis,

23
00:02:08,719 --> 00:02:16,099
testicles, vagina and ovaries, okay? So those are the primary sex characteristics.

24
00:02:16,099 --> 00:02:19,699
Let's listen to the secondary.

25
00:02:19,699 --> 00:02:30,699
Secondary sex characteristics, such as facial hair, are also physical differences, but they aren't directly related to reproduction.

26
00:02:30,699 --> 00:02:35,699
Okay, for example, secondary sex characteristics, we have facial hair.

27
00:02:35,699 --> 00:02:43,699
During puberty, that we are going to read about it, you start growing hair in your face.

28
00:02:43,699 --> 00:02:49,879
we grow facial hair so those are differences between our bodies but they

29
00:02:49,879 --> 00:02:57,620
are not related to reproduction they are changes changes in your body so it facial

30
00:02:57,620 --> 00:03:05,860
hair for instance is a secondary sex characteristic okay let's continue

31
00:03:05,860 --> 00:03:11,659
secondary sex characteristics start appearing during a life stage called

32
00:03:11,659 --> 00:03:19,080
puberty as the reproductive organs develop okay as the reproductive organ

33
00:03:19,080 --> 00:03:28,539
develop remember that reproductive organ penis testicles vagina etc so also we

34
00:03:28,539 --> 00:03:35,240
some secondary sex characteristics appear for example facial hair this boy

35
00:03:35,240 --> 00:03:42,139
if we read here men's facial hair begins to grow during puberty and in this

36
00:03:42,139 --> 00:03:47,780
picture he's shaving because he has got hair in his face he has got a facial

37
00:03:47,780 --> 00:03:52,699
hair so the secondary sex characteristics appear during a life

38
00:03:52,699 --> 00:03:58,479
stage a life stage una etapa de nuestra vida which is called puberty la pubertad

39
00:03:58,479 --> 00:04:06,639
the secondary sex characteristics appear during puberty when is puberty most

40
00:04:06,639 --> 00:04:14,240
girls go through puberty between the ages of 10 and 14 most boys between the

41
00:04:14,240 --> 00:04:22,420
ages of 11 and 16 okay so the girls go through puberty between the ages of 10

42
00:04:22,420 --> 00:04:29,500
and 14 and the boys between the ages of 11 and 16 it depends on each person

43
00:04:29,500 --> 00:04:35,540
maybe a girl goes through puberty when she's 10 and other girl goes through

44
00:04:35,540 --> 00:04:45,800
puberty when she's 13 it depends on our bodies okay human beings like many other

45
00:04:45,800 --> 00:04:52,040
living things reproduce by sexual reproduction this is how they have

46
00:04:52,040 --> 00:04:58,819
children. The reproductive process involves the combination of female and

47
00:04:58,819 --> 00:05:06,920
male reproductive cells. When these cells join together during fertilization, a

48
00:05:06,920 --> 00:05:14,959
fetus is formed. It grows inside its mother's uterus for about nine months.

49
00:05:14,959 --> 00:05:24,939
during birth the fetus is expelled and the baby is born okay so as many other

50
00:05:24,939 --> 00:05:31,720
animals human beings reproduce by sexual reproduction okay we have sexual

51
00:05:31,720 --> 00:05:38,160
reproduction reproduction sexual I'm going to show you a picture and we need

52
00:05:38,160 --> 00:05:46,699
two types of cells, dos tipos de células. The sperm cell here and the egg cell here.

53
00:05:46,699 --> 00:05:54,839
Sperm cell in Spanish, espermatozoide, and egg cell in Spanish, óvulo, okay? When

54
00:05:54,839 --> 00:06:02,459
these two cells combine, a fetus is formed or starts to form, okay? The baby

55
00:06:02,459 --> 00:06:10,379
starts to grow and when the baby is in the mom's womb for about nine months the

56
00:06:10,379 --> 00:06:15,279
baby is born. Everybody knows that but in this unit we are going to study this

57
00:06:15,279 --> 00:06:20,399
process in deep, en profundidad. This is just the introduction. Only you need

58
00:06:20,399 --> 00:06:25,339
to know that there are two type of reproductive cells the sperm cell and

59
00:06:25,339 --> 00:06:37,449
the egg cell okay so let's correct the exercise exercise one read the text and

60
00:06:37,449 --> 00:06:42,850
complete the sentences in your notebook a sexual reproduction involves the

61
00:06:42,850 --> 00:06:49,209
combining of and you have the answer in the text female and male reproductive

62
00:06:49,209 --> 00:06:54,670
cell remember the egg cell and the sperm cell the picture that I have just shown

63
00:06:54,670 --> 00:07:03,610
you B the differences between male and female bodies are called remember that I

64
00:07:03,610 --> 00:07:09,269
told you before the first part of the text the difference the differences

65
00:07:09,269 --> 00:07:15,790
between a body a male body and a female body are called sex characteristics and

66
00:07:15,790 --> 00:07:20,730
remember that we have two types of sex characteristics primary and secondary

67
00:07:20,730 --> 00:07:40,629
And finally, C, sex characteristics, the differences develop during a life stage, una etapa de nuestra vida, these differences, these characteristics develop during a life stage called puberty, ok, pubertad, puberty.

68
00:07:42,410 --> 00:07:45,339
Let's go to number two.

69
00:07:45,339 --> 00:07:52,240
look at the pictures and answer and answer the questions with a partner

70
00:07:52,240 --> 00:07:58,939
well we don't have a partner but we are going to do it hey does picture D this

71
00:07:58,939 --> 00:08:05,339
one represent puberty birth or sex characteristics so is this picture a

72
00:08:05,339 --> 00:08:15,060
life stage in which we start developing a change in our body

73
00:08:15,339 --> 00:08:22,220
For example, facial hair at the age of 11, 10, 14. No.

74
00:08:24,060 --> 00:08:28,420
Sex characteristics? No. This is a birth.

75
00:08:28,839 --> 00:08:31,439
The picture D represents birth.

76
00:08:31,680 --> 00:08:35,480
Nacimiento, a baby, is born. Here.

77
00:08:37,500 --> 00:08:39,899
Picture D represents birth.

78
00:08:40,940 --> 00:08:44,740
And B. Which people are going through puberty?

79
00:08:44,740 --> 00:09:02,500
How do you know? Which people are going through a life stage? Well, here, I would eliminate these two pictures because they are not people. And here, is this baby baby going through puberty?

80
00:09:02,500 --> 00:09:08,740
Is he about 11, 12 years old and he's growing facial hair?

81
00:09:09,419 --> 00:09:17,779
No, the people who are going through puberty are these two guys, this girl and this boy.

82
00:09:18,559 --> 00:09:19,419
And how do you know?

83
00:09:19,940 --> 00:09:23,799
Well, because, for example, this boy has got facial hair.

84
00:09:26,529 --> 00:09:33,429
The people in picture C are going through puberty because they look about 12 or 13 years old.

85
00:09:33,429 --> 00:09:39,830
This baby doesn't look about 12 or 13 years old, but these two guys, they do.

86
00:09:40,210 --> 00:09:46,370
They look about 12 or 13, and they have some secondary sex characteristics.

87
00:09:46,629 --> 00:09:48,029
For example, facial hair.

88
00:09:48,750 --> 00:09:51,970
They have got some second sex characteristics.

89
00:09:53,570 --> 00:09:54,330
Good.

90
00:09:54,830 --> 00:09:57,730
And finally, oh, the diagram.

91
00:09:57,730 --> 00:10:09,409
Classify these secondary sex characteristics in a Venn diagram. Male, female, or both. Then listen and check.

92
00:10:10,210 --> 00:10:10,429
Okay.

93
00:10:11,570 --> 00:10:17,889
Female secondary sex characteristics include wider hips and larger breasts.

94
00:10:17,889 --> 00:10:27,889
Male secondary sex characteristics include facial hair, chest hair, wider shoulders and a deeper voice.

95
00:10:27,889 --> 00:10:38,889
Two secondary sex characteristics are shared by men and women. Both have pubic hair and underarm hair.

96
00:10:38,889 --> 00:10:48,730
okay so for example male what are the secondary sex characteristics the male

97
00:10:48,730 --> 00:10:56,169
secondary sex characteristics so we have facial hair oh wait oh let's go one be

98
00:10:56,169 --> 00:11:04,889
one cubic hair both male and female boys and girls grow pubic hair pubic hair is

99
00:11:04,889 --> 00:11:12,029
hair near your reproductive organ near your penis or near your vagina okay then

100
00:11:12,029 --> 00:11:25,570
we have wider hips it's female okay deeper voice deeper voice male the boys

101
00:11:25,570 --> 00:11:40,529
Underarm hair. Underarm hair means hair that is under your arm, in your armpit, en tus axilas. Hair in your armpits. Underarm hair.

102
00:11:40,529 --> 00:11:54,529
So, both wider shoulders, los hombros más anchos, wider shoulders. Male breasts. Female breasts are pechos.

103
00:11:55,570 --> 00:12:05,909
and finally chest hair male okay so in class we will study that maybe some boys

104
00:12:05,909 --> 00:12:12,570
have got the female sex characteristics well for example some female can have the male

105
00:12:12,570 --> 00:12:16,789
sex characteristics but we will study this in class and you can ask you can

106
00:12:16,789 --> 00:12:21,809
ask me as many questions as you want okay so that's it guys remember to copy

107
00:12:21,809 --> 00:12:29,169
the vocabulary word which is this one sex characteristics thank you bye bye
