Good morning guys, so today we are going to correct the activities of natural sciences on page 36 00:00:01
I asked you to do exercises 1, 2 and 3 00:00:09
But first we are going to listen to the text because here I have the listening 00:00:13
I'm going to explain it a little bit and then we will correct the activities. Okay, let's start 00:00:17
Page 37 00:00:24
there are physical differences between male and female bodies these differences are called sex 00:00:27
characteristics okay this unit we are going to study about reproduction and here we can read 00:00:37
we can listen that we have well our bodies are different it's not the same the body of a boy 00:00:45
than the body of a girl and there are because there are some differences 00:00:53
between our bodies and these differences are called sex characteristics 00:00:57
características sexuales the sex characteristics are the differences 00:01:03
between the male body and the female body el cuerpo masculino y el cuerpo 00:01:08
femenino el cuerpo de los hombres y el cuerpo de las mujeres ok the differences 00:01:13
between our bodies are called sex characteristics and we have two types of 00:01:17
sex characteristics, we have the primary and the secondary. The primary sex 00:01:22
characteristics and the secondary sex characteristics, the primary differences 00:01:28
and the secondary differences. Let's continue. 00:01:33
primary sex characteristics are the physical differences between the male 00:01:38
and female reproductive organs. Okay so the primary sex characteristics are the 00:01:43
differences between our reproductive organ. Reproductive organ in Spanish es 00:01:50
órgano reproductor. So the differences between our reproductive organs are the 00:01:57
primary sex characteristics. Reproductive organs are the penis, 00:02:02
testicles, vagina and ovaries, okay? So those are the primary sex characteristics. 00:02:08
Let's listen to the secondary. 00:02:16
Secondary sex characteristics, such as facial hair, are also physical differences, but they aren't directly related to reproduction. 00:02:19
Okay, for example, secondary sex characteristics, we have facial hair. 00:02:30
During puberty, that we are going to read about it, you start growing hair in your face. 00:02:35
we grow facial hair so those are differences between our bodies but they 00:02:43
are not related to reproduction they are changes changes in your body so it facial 00:02:49
hair for instance is a secondary sex characteristic okay let's continue 00:02:57
secondary sex characteristics start appearing during a life stage called 00:03:05
puberty as the reproductive organs develop okay as the reproductive organ 00:03:11
develop remember that reproductive organ penis testicles vagina etc so also we 00:03:19
some secondary sex characteristics appear for example facial hair this boy 00:03:28
if we read here men's facial hair begins to grow during puberty and in this 00:03:35
picture he's shaving because he has got hair in his face he has got a facial 00:03:42
hair so the secondary sex characteristics appear during a life 00:03:47
stage a life stage una etapa de nuestra vida which is called puberty la pubertad 00:03:52
the secondary sex characteristics appear during puberty when is puberty most 00:03:58
girls go through puberty between the ages of 10 and 14 most boys between the 00:04:06
ages of 11 and 16 okay so the girls go through puberty between the ages of 10 00:04:14
and 14 and the boys between the ages of 11 and 16 it depends on each person 00:04:22
maybe a girl goes through puberty when she's 10 and other girl goes through 00:04:29
puberty when she's 13 it depends on our bodies okay human beings like many other 00:04:35
living things reproduce by sexual reproduction this is how they have 00:04:45
children. The reproductive process involves the combination of female and 00:04:52
male reproductive cells. When these cells join together during fertilization, a 00:04:58
fetus is formed. It grows inside its mother's uterus for about nine months. 00:05:06
during birth the fetus is expelled and the baby is born okay so as many other 00:05:14
animals human beings reproduce by sexual reproduction okay we have sexual 00:05:24
reproduction reproduction sexual I'm going to show you a picture and we need 00:05:31
two types of cells, dos tipos de células. The sperm cell here and the egg cell here. 00:05:38
Sperm cell in Spanish, espermatozoide, and egg cell in Spanish, óvulo, okay? When 00:05:46
these two cells combine, a fetus is formed or starts to form, okay? The baby 00:05:54
starts to grow and when the baby is in the mom's womb for about nine months the 00:06:02
baby is born. Everybody knows that but in this unit we are going to study this 00:06:10
process in deep, en profundidad. This is just the introduction. Only you need 00:06:15
to know that there are two type of reproductive cells the sperm cell and 00:06:20
the egg cell okay so let's correct the exercise exercise one read the text and 00:06:25
complete the sentences in your notebook a sexual reproduction involves the 00:06:37
combining of and you have the answer in the text female and male reproductive 00:06:42
cell remember the egg cell and the sperm cell the picture that I have just shown 00:06:49
you B the differences between male and female bodies are called remember that I 00:06:54
told you before the first part of the text the difference the differences 00:07:03
between a body a male body and a female body are called sex characteristics and 00:07:09
remember that we have two types of sex characteristics primary and secondary 00:07:15
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. 00:07:20
Let's go to number two. 00:07:42
look at the pictures and answer and answer the questions with a partner 00:07:45
well we don't have a partner but we are going to do it hey does picture D this 00:07:52
one represent puberty birth or sex characteristics so is this picture a 00:07:58
life stage in which we start developing a change in our body 00:08:05
For example, facial hair at the age of 11, 10, 14. No. 00:08:15
Sex characteristics? No. This is a birth. 00:08:24
The picture D represents birth. 00:08:28
Nacimiento, a baby, is born. Here. 00:08:31
Picture D represents birth. 00:08:37
And B. Which people are going through puberty? 00:08:40
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? 00:08:44
Is he about 11, 12 years old and he's growing facial hair? 00:09:02
No, the people who are going through puberty are these two guys, this girl and this boy. 00:09:09
And how do you know? 00:09:18
Well, because, for example, this boy has got facial hair. 00:09:19
The people in picture C are going through puberty because they look about 12 or 13 years old. 00:09:26
This baby doesn't look about 12 or 13 years old, but these two guys, they do. 00:09:33
They look about 12 or 13, and they have some secondary sex characteristics. 00:09:40
For example, facial hair. 00:09:46
They have got some second sex characteristics. 00:09:48
Good. 00:09:53
And finally, oh, the diagram. 00:09:54
Classify these secondary sex characteristics in a Venn diagram. Male, female, or both. Then listen and check. 00:09:57
Okay. 00:10:10
Female secondary sex characteristics include wider hips and larger breasts. 00:10:11
Male secondary sex characteristics include facial hair, chest hair, wider shoulders and a deeper voice. 00:10:17
Two secondary sex characteristics are shared by men and women. Both have pubic hair and underarm hair. 00:10:27
okay so for example male what are the secondary sex characteristics the male 00:10:38
secondary sex characteristics so we have facial hair oh wait oh let's go one be 00:10:48
one cubic hair both male and female boys and girls grow pubic hair pubic hair is 00:10:56
hair near your reproductive organ near your penis or near your vagina okay then 00:11:04
we have wider hips it's female okay deeper voice deeper voice male the boys 00:11:12
Underarm hair. Underarm hair means hair that is under your arm, in your armpit, en tus axilas. Hair in your armpits. Underarm hair. 00:11:25
So, both wider shoulders, los hombros más anchos, wider shoulders. Male breasts. Female breasts are pechos. 00:11:40
and finally chest hair male okay so in class we will study that maybe some boys 00:11:55
have got the female sex characteristics well for example some female can have the male 00:12:05
sex characteristics but we will study this in class and you can ask you can 00:12:12
ask me as many questions as you want okay so that's it guys remember to copy 00:12:16
the vocabulary word which is this one sex characteristics thank you bye bye 00:12:21
