Hello guys, so today we are going to study pages 14 and 15 of Natural Sciences, okay?

2
00:00:10,419 --> 00:00:13,279
The last two pages of this unit.

3
00:00:14,300 --> 00:00:17,699
The title is How can we keep our nervous system healthy?

4
00:00:18,320 --> 00:00:24,100
Okay, we are going to study different ways in order to keep our nervous system healthy.

5
00:00:24,539 --> 00:00:30,120
The meaning of healthy is sano, saludable, very good in Spanish.

6
00:00:30,120 --> 00:00:35,280
okay let's start reading to keep your nervous system healthy you should look

7
00:00:35,280 --> 00:00:41,100
after your brain and your muscles look after what's the meaning of this verb

8
00:00:41,100 --> 00:00:49,719
it's a phrasal verb in Spanish it means cuidar so we should look after our brain

9
00:00:49,719 --> 00:00:55,560
and our muscles it's important because the nervous system is responsible for

10
00:00:55,560 --> 00:01:04,760
for movement breathing and your heart beat ok let's start with how to keep our brain

11
00:01:04,760 --> 00:01:11,280
healthy in order to keep your brain healthy you should exercise it so we have to exercise

12
00:01:11,280 --> 00:01:19,200
our brain how you can do this by doing puzzles and playing thinking games like I spy guess

13
00:01:19,200 --> 00:01:27,060
who or for example Sudokus are a good way in order to exercise our brain you

14
00:01:27,060 --> 00:01:32,159
can also exercise your brain by training your memory for example you go to your

15
00:01:32,159 --> 00:01:38,200
house and you start okay this morning what was my what were my classmates

16
00:01:38,200 --> 00:01:44,459
wearing so for example Remaesa was wearing a pink jumper Irene was

17
00:01:44,459 --> 00:01:51,140
wearing a blue t-shirt like this it's a good way to train our memory and solving

18
00:01:51,140 --> 00:01:58,560
mathematical or linguistic problems it's also important to rest your brain the

19
00:01:58,560 --> 00:02:06,840
meaning of rest in Spanish descansar so it's important to rest our brain by

20
00:02:06,840 --> 00:02:13,379
sleeping about 10 hours a night you are giving your brain plenty of time to rest

21
00:02:13,379 --> 00:02:21,300
and recharge itself so we should sleep at least 10 hours a night about 10 hours

22
00:02:21,300 --> 00:02:27,280
a night so you can go to bed at 10 o'clock in the evening and then wake up

23
00:02:27,280 --> 00:02:35,219
at 8 o'clock in the morning and then a balanced diet is also important for a

24
00:02:35,219 --> 00:02:41,860
healthy brain so we need to eat or to have a balanced diet just like other

25
00:02:41,860 --> 00:02:48,280
organs your brain needs energy from food in order to function well we get the

26
00:02:48,280 --> 00:02:53,979
energy that we need from the food so the food that we eat needs to be balanced we

27
00:02:53,979 --> 00:03:01,139
need to eat vegetables meat fish pasta it needs to be balanced not only sugar

28
00:03:01,139 --> 00:03:08,620
and you should also drink lots of water not soft drinks water dehydration can

29
00:03:08,620 --> 00:03:14,300
cause memory problems or confusion we have to drink a lot of water during the

30
00:03:14,300 --> 00:03:21,400
day these are the recommendation in in recommendations in order to have or to

31
00:03:21,400 --> 00:03:28,180
keep our brain healthy now how can we keep our muscles healthy let's read in

32
00:03:28,180 --> 00:03:33,520
order to keep your muscles healthy it's important to do regular exercise for

33
00:03:33,520 --> 00:03:40,780
example running, swimming, gymnastics, trampoline, whatever. Physical

34
00:03:40,780 --> 00:03:46,539
education with Annabelle is a good example of exercise. This guarantees a

35
00:03:46,539 --> 00:03:53,379
regular supply of blood and oxygen to your muscles. By doing exercise you are

36
00:03:53,379 --> 00:04:00,219
also exercising your heart and lungs. The meaning of lungs in Spanish we have two

37
00:04:00,219 --> 00:04:09,819
lungs in our body pulmones okay so doing exercise by doing exercise you are also exercising your

38
00:04:09,819 --> 00:04:16,779
lungs and your heart this helps your nervous system to control involuntary movements such

39
00:04:16,779 --> 00:04:23,980
as breathing or blinking so in order to keep our muscles healthy we have to do a lot of exercise

40
00:04:23,980 --> 00:04:36,120
For example, instead of taking the elevator, el ascensor, you can go up the stairs, for example.

41
00:04:36,120 --> 00:04:38,120
It's a good idea.

42
00:04:38,120 --> 00:04:43,120
And finally, what about health and safety at school?

43
00:04:43,120 --> 00:04:50,120
When we can't see or hear well, our brains have to work harder to interpret the information they receive.

44
00:04:50,120 --> 00:04:55,120
So it's important to get your eyesight and hearing checked regularly.

45
00:04:55,120 --> 00:05:11,100
So we need to go to the doctor and we need to get our eyesight and hearing checked, because if we can't see or hear well, our brain is going to work harder and we are going to feel tired, more tired.

46
00:05:12,839 --> 00:05:19,860
Make sure that you can see the teacher, the board and your notebook clearly and that you can hear the teacher well.

47
00:05:19,860 --> 00:05:24,660
well in this year it's different because we are in the gym and we have this situation

48
00:05:24,660 --> 00:05:30,259
but in general you need to hear the teacher well you need to see your notebook clearly you

49
00:05:30,259 --> 00:05:38,180
you need to see the board okay there should be good light good lightning in your classroom

50
00:05:38,180 --> 00:05:44,819
check that there aren't objects in your way when you move about or sharp edges that could cut or

51
00:05:44,819 --> 00:05:49,620
hurt you so for example when I say please stop running don't run in the

52
00:05:49,620 --> 00:05:54,959
classes because you might fall down and there are a lot of edges picos sharp

53
00:05:54,959 --> 00:06:01,860
edges for example the tables have got sharp edges the classroom isn't a safe

54
00:06:01,860 --> 00:06:08,040
place to run around in because it's full of obstacles and sharp corners this is

55
00:06:08,040 --> 00:06:13,139
what I was saying the class is full of obstacles for example chairs tables

56
00:06:13,139 --> 00:06:19,139
students people and sharp corners the corners of the cupboard the corners of

57
00:06:19,139 --> 00:06:28,019
the tables etc okay so if you have any question please ask me or write an email

58
00:06:28,019 --> 00:06:31,800
okay and I will answer as soon as possible I will reply as soon as

59
00:06:31,800 --> 00:06:37,600
possible now you have to do the exercises okay the exercises are in the

60
00:06:37,600 --> 00:06:45,100
list of activities that I sent you okay bye bye guys
