1
00:00:00,000 --> 00:00:08,839
morning kids how are you feeling today i hope you all are fantastic i will tell you how i am

2
00:00:08,839 --> 00:00:20,460
today i am feeling excited and do you know why because yesterday i made big chocolate cake

3
00:00:20,460 --> 00:00:29,260
that i'm going to eat today so i hope it's delicious well we are going to start a new

4
00:00:29,260 --> 00:00:36,920
Unit of Natural Science, which is the Unit 6, and it's called Matter. All the things that we

5
00:00:36,920 --> 00:00:46,479
will learn today are on pages 4, 6, and 7 of your Natural Science book, so you can open it and

6
00:00:46,479 --> 00:00:56,600
follow me, okay? So, if you go to page 4, you will see the main picture that I have on the left,

7
00:00:56,600 --> 00:01:00,719
and what can you see in the picture?

8
00:01:02,100 --> 00:01:03,979
I will tell you what I see.

9
00:01:05,200 --> 00:01:09,280
There is a big garden in a house.

10
00:01:09,980 --> 00:01:14,840
There is a parking where there is a blue car.

11
00:01:15,739 --> 00:01:17,200
There is a bicycle.

12
00:01:18,340 --> 00:01:20,500
There is a big apple tree.

13
00:01:21,680 --> 00:01:24,920
There are some presents.

14
00:01:24,920 --> 00:01:37,370
there is a dog there is a fun game on the grass of the garden and there are some people

15
00:01:37,370 --> 00:01:45,469
who are celebrating a birthday party yes and there is a cake in the middle of the table

16
00:01:45,469 --> 00:01:56,870
the cake the same cake as i made yesterday well and you will be wondering what does this picture

17
00:01:56,870 --> 00:01:58,409
have to do with matter?

18
00:02:00,090 --> 00:02:03,409
This picture has to do with matter

19
00:02:03,409 --> 00:02:06,689
because matter is

20
00:02:06,689 --> 00:02:10,030
everything that exists.

21
00:02:10,610 --> 00:02:12,870
Yes, everything is matter.

22
00:02:13,729 --> 00:02:15,930
So all the things that are in the picture

23
00:02:15,930 --> 00:02:17,330
are matter.

24
00:02:18,810 --> 00:02:22,610
The tree, the car, the grass,

25
00:02:22,729 --> 00:02:24,389
the presents, the people,

26
00:02:24,389 --> 00:02:28,069
and even the air that you can't see.

27
00:02:28,949 --> 00:02:31,090
The air is gas.

28
00:02:31,909 --> 00:02:36,409
And although you can't see gas, it exists.

29
00:02:37,310 --> 00:02:40,129
And I will prove this with a video.

30
00:02:40,729 --> 00:02:41,870
This video on the right.

31
00:02:42,550 --> 00:02:50,009
You will see a girl who is going to put a type of gas inside the container, okay?

32
00:02:50,009 --> 00:02:58,169
And then the guy in the middle will put an aluminum boat in the container too.

33
00:02:58,990 --> 00:03:01,990
So you will see what happens to the aluminum boat.

34
00:03:10,860 --> 00:03:18,199
So she's putting some gas and now the guy is putting the aluminum boat.

35
00:03:25,710 --> 00:03:29,050
Yes, the aluminum boat is not floating.

36
00:03:29,789 --> 00:03:30,150
No, no.

37
00:03:30,629 --> 00:03:34,189
It is just on the gas that the girl put before.

38
00:03:34,530 --> 00:03:37,370
So you can see that gas exists.

39
00:03:37,389 --> 00:03:53,699
although you can't see it. Let's see the next slide, if I can show you. The next slide tells

40
00:03:53,699 --> 00:04:01,439
us that matter is made up of different materials. There are two types of materials that matter

41
00:04:01,439 --> 00:04:12,969
is made up of? Natural materials and artificial materials. There are two types.

42
00:04:13,889 --> 00:04:22,480
Natural materials are the materials that come from minerals, like this rock.

43
00:04:24,360 --> 00:04:31,899
Materials that come from plants, like cotton. Cotton is what we use to make t-shirts.

44
00:04:31,899 --> 00:04:43,300
this t-shirt is made up of cotton materials that come from animals like wool this wool that is made

45
00:04:43,300 --> 00:04:53,100
from the sheep and then on the other side we have artificial materials the artificial materials

46
00:04:53,100 --> 00:05:01,120
are not made by nature as the natural materials artificial materials are made and created by

47
00:05:01,120 --> 00:05:11,379
humans, by people, like glass, paper, and plastic.

48
00:05:12,720 --> 00:05:19,019
Okay, these are the two types of materials, natural materials that are made by nature

49
00:05:19,019 --> 00:05:23,139
and artificial materials that are created by people.

50
00:05:24,040 --> 00:05:27,860
Now we will see the properties of matter.

51
00:05:27,860 --> 00:05:34,279
Matter has two properties, mass and volume

52
00:05:34,279 --> 00:05:41,040
Mass has to do with how heavy something is

53
00:05:41,040 --> 00:05:47,300
Mass is the amount of matter that something has

54
00:05:47,300 --> 00:05:57,839
For example, in this picture we can see that the red box has more mass than the blue box

55
00:05:57,839 --> 00:06:01,420
if we use a comparative sentence

56
00:06:01,420 --> 00:06:03,980
that's what we are learning in English

57
00:06:03,980 --> 00:06:06,360
we can say this sentence

58
00:06:06,360 --> 00:06:09,180
the red box is

59
00:06:09,180 --> 00:06:13,579
heavier than the blue box

60
00:06:13,579 --> 00:06:14,259
ok?

61
00:06:14,759 --> 00:06:16,680
so that's why the blue box

62
00:06:16,680 --> 00:06:20,160
doesn't have as much mass

63
00:06:20,160 --> 00:06:21,800
as the red box

64
00:06:21,800 --> 00:06:25,860
and the other property

65
00:06:25,860 --> 00:06:27,220
volume

66
00:06:27,220 --> 00:06:32,699
Volume has to do with how big something is

67
00:06:32,699 --> 00:06:39,600
So volume is the space that matter occupies

68
00:06:39,600 --> 00:06:44,180
For example, in this picture on the right

69
00:06:44,180 --> 00:06:47,839
We have a blue box again and a red box

70
00:06:47,839 --> 00:06:50,920
So which one has more volume?

71
00:06:51,779 --> 00:06:55,379
The blue box has more volume than the red box

72
00:06:55,379 --> 00:07:03,120
because the blue box is bigger, so you can see that it has more volume, it occupies more space.

73
00:07:03,819 --> 00:07:08,879
These are the properties of matter, mass and volume.

74
00:07:09,800 --> 00:07:11,160
And now we will see an example.

75
00:07:12,740 --> 00:07:16,420
We have a paper boat and a rubber.

76
00:07:18,339 --> 00:07:20,720
Let's talk about the properties of matter.

77
00:07:20,720 --> 00:07:23,759
first of all

78
00:07:23,759 --> 00:07:26,759
do you think they are natural materials

79
00:07:26,759 --> 00:07:28,600
or artificial materials

80
00:07:28,600 --> 00:07:33,069
they are artificial materials

81
00:07:33,069 --> 00:07:34,930
because paper is artificial

82
00:07:34,930 --> 00:07:36,250
and rubber too

83
00:07:36,250 --> 00:07:38,370
well

84
00:07:38,370 --> 00:07:41,269
now we will see which one

85
00:07:41,269 --> 00:07:42,810
which ones are

86
00:07:42,810 --> 00:07:45,110
the properties

87
00:07:45,110 --> 00:07:48,310
which one has more mass

88
00:07:48,310 --> 00:07:51,290
which one is heavy

89
00:07:51,290 --> 00:07:52,689
which one has more mass

90
00:07:53,490 --> 00:07:55,629
The rubber has more mass.

91
00:07:56,490 --> 00:07:58,629
And which one has more volume?

92
00:07:59,009 --> 00:08:00,589
Which one occupies more space?

93
00:08:01,529 --> 00:08:04,629
Yes, the paper boat has more volume.

94
00:08:05,649 --> 00:08:12,589
So, although the rubber is smaller, it has more mass than the paper boat.

95
00:08:12,589 --> 00:08:18,269
And the paper boat has more volume because it occupies more space.

96
00:08:18,269 --> 00:08:23,470
now we will see the states of matter

97
00:08:23,470 --> 00:08:26,410
there are three states of matter

98
00:08:26,410 --> 00:08:31,769
solid, liquid and gas

99
00:08:31,769 --> 00:08:36,789
solid like an apple

100
00:08:36,789 --> 00:08:38,330
which is solid

101
00:08:38,330 --> 00:08:42,409
liquid like this orange juice

102
00:08:42,409 --> 00:08:46,230
and gas like smoke

103
00:08:46,230 --> 00:08:52,149
and the characteristics of these states are

104
00:08:52,149 --> 00:08:55,110
the first one, solid.

105
00:08:56,570 --> 00:08:58,730
If you look at this table,

106
00:08:59,070 --> 00:09:03,669
you see that solids have always the same shape

107
00:09:03,669 --> 00:09:06,169
like this pencil case.

108
00:09:06,169 --> 00:09:10,370
My pencil case has always the same shape.

109
00:09:10,669 --> 00:09:14,269
It doesn't become bigger or smaller.

110
00:09:14,990 --> 00:09:15,970
It's always the same.

111
00:09:15,970 --> 00:09:31,090
and they occupy the same space okay then liquids liquids take the shape of the

112
00:09:31,090 --> 00:09:45,029
container okay like this this water takes the shape of this glass and

113
00:09:45,029 --> 00:09:51,590
liquids have the same volume they don't change although you change the container

114
00:09:51,590 --> 00:10:03,750
the volume is always the same. Gas. Gas has the shape of the container and it occupies the space

115
00:10:03,750 --> 00:10:13,970
of the container. For example, the air in this room takes the shape of the room, which is a square,

116
00:10:13,970 --> 00:10:20,409
And it also occupies the space of the room.

117
00:10:20,909 --> 00:10:23,370
What happens if we open the window?

118
00:10:23,850 --> 00:10:27,309
The air goes out as well.

119
00:10:27,629 --> 00:10:29,789
It goes out of the window as well.

120
00:10:30,490 --> 00:10:31,629
It spreads.

121
00:10:32,330 --> 00:10:37,190
So gas fills the space of the container.

122
00:10:37,710 --> 00:10:37,970
Okay?

123
00:10:37,970 --> 00:10:51,889
Now, we will see an experiment to see that liquid takes the shape of the container and the volume doesn't change.

124
00:10:52,450 --> 00:11:17,299
Look, there were 100 milliliters and the water is taking the shape of the different types of containers.

125
00:11:17,299 --> 00:11:30,399
the bottle the glass and now this long tube that although it's thinner it it is always the same

126
00:11:30,399 --> 00:11:41,159
volume you will see the water is has the same volume 100 milliliters the same as the ones we

127
00:11:41,159 --> 00:11:49,580
had before, the original volume. So, liquid changes and takes the shape of the different

128
00:11:49,580 --> 00:11:55,779
containers where you pour it, but the volume is always the same, although you change the container.

129
00:11:56,639 --> 00:12:06,200
What about gas? Let's see gas. There is another experiment to prove that gas has a volume and a

130
00:12:06,200 --> 00:12:16,639
For example, we are going to take a balloon and first the balloon is empty, like this one.

131
00:12:17,320 --> 00:12:19,759
But what happens if we blow the balloon?

132
00:12:20,320 --> 00:12:33,720
It is full of air and now the air, the gas, takes the shape of the balloon and it occupies a space, as you can see.

133
00:12:33,720 --> 00:12:45,139
now let's see and let's prove that gas has a mass in the video on the right there are two balloons

134
00:12:45,139 --> 00:12:52,360
one is empty and the other is full and you will see that the balloon which is full

135
00:12:52,360 --> 00:13:04,879
has more mass than the empty balloon it is heavier it has more mass so that's why gas

136
00:13:04,879 --> 00:13:17,279
which is there inside, has a volume and a mass. Today we learned a few new words. The first one

137
00:13:17,279 --> 00:13:24,000
is container, which is a recipient where we keep things and put things inside.

138
00:13:25,519 --> 00:13:33,759
Full and empty. You can see the first container is full of popcorn and the second container

139
00:13:33,759 --> 00:13:43,200
is empty because there isn't popcorn and the last one balloon you can see the picture of a balloon

140
00:13:44,080 --> 00:13:51,200
and now you can take your little notebook write these new words and draw pictures

141
00:13:51,200 --> 00:13:59,519
about them okay i hope you like this session see you later alligators take care
