morning kids how are you feeling today i hope you all are fantastic i will tell you how i am 00:00:00
today i am feeling excited and do you know why because yesterday i made big chocolate cake 00:00:08
that i'm going to eat today so i hope it's delicious well we are going to start a new 00:00:20
Unit of Natural Science, which is the Unit 6, and it's called Matter. All the things that we 00:00:29
will learn today are on pages 4, 6, and 7 of your Natural Science book, so you can open it and 00:00:36
follow me, okay? So, if you go to page 4, you will see the main picture that I have on the left, 00:00:46
and what can you see in the picture? 00:00:56
I will tell you what I see. 00:01:02
There is a big garden in a house. 00:01:05
There is a parking where there is a blue car. 00:01:09
There is a bicycle. 00:01:15
There is a big apple tree. 00:01:18
There are some presents. 00:01:21
there is a dog there is a fun game on the grass of the garden and there are some people 00:01:24
who are celebrating a birthday party yes and there is a cake in the middle of the table 00:01:37
the cake the same cake as i made yesterday well and you will be wondering what does this picture 00:01:45
have to do with matter? 00:01:56
This picture has to do with matter 00:02:00
because matter is 00:02:03
everything that exists. 00:02:06
Yes, everything is matter. 00:02:10
So all the things that are in the picture 00:02:13
are matter. 00:02:15
The tree, the car, the grass, 00:02:18
the presents, the people, 00:02:22
and even the air that you can't see. 00:02:24
The air is gas. 00:02:28
And although you can't see gas, it exists. 00:02:31
And I will prove this with a video. 00:02:37
This video on the right. 00:02:40
You will see a girl who is going to put a type of gas inside the container, okay? 00:02:42
And then the guy in the middle will put an aluminum boat in the container too. 00:02:50
So you will see what happens to the aluminum boat. 00:02:58
So she's putting some gas and now the guy is putting the aluminum boat. 00:03:10
Yes, the aluminum boat is not floating. 00:03:25
No, no. 00:03:29
It is just on the gas that the girl put before. 00:03:30
So you can see that gas exists. 00:03:34
although you can't see it. Let's see the next slide, if I can show you. The next slide tells 00:03:37
us that matter is made up of different materials. There are two types of materials that matter 00:03:53
is made up of? Natural materials and artificial materials. There are two types. 00:04:01
Natural materials are the materials that come from minerals, like this rock. 00:04:13
Materials that come from plants, like cotton. Cotton is what we use to make t-shirts. 00:04:24
this t-shirt is made up of cotton materials that come from animals like wool this wool that is made 00:04:31
from the sheep and then on the other side we have artificial materials the artificial materials 00:04:43
are not made by nature as the natural materials artificial materials are made and created by 00:04:53
humans, by people, like glass, paper, and plastic. 00:05:01
Okay, these are the two types of materials, natural materials that are made by nature 00:05:12
and artificial materials that are created by people. 00:05:19
Now we will see the properties of matter. 00:05:24
Matter has two properties, mass and volume 00:05:27
Mass has to do with how heavy something is 00:05:34
Mass is the amount of matter that something has 00:05:41
For example, in this picture we can see that the red box has more mass than the blue box 00:05:47
if we use a comparative sentence 00:05:57
that's what we are learning in English 00:06:01
we can say this sentence 00:06:03
the red box is 00:06:06
heavier than the blue box 00:06:09
ok? 00:06:13
so that's why the blue box 00:06:14
doesn't have as much mass 00:06:16
as the red box 00:06:20
and the other property 00:06:21
volume 00:06:25
Volume has to do with how big something is 00:06:27
So volume is the space that matter occupies 00:06:32
For example, in this picture on the right 00:06:39
We have a blue box again and a red box 00:06:44
So which one has more volume? 00:06:47
The blue box has more volume than the red box 00:06:51
because the blue box is bigger, so you can see that it has more volume, it occupies more space. 00:06:55
These are the properties of matter, mass and volume. 00:07:03
And now we will see an example. 00:07:09
We have a paper boat and a rubber. 00:07:12
Let's talk about the properties of matter. 00:07:18
first of all 00:07:20
do you think they are natural materials 00:07:23
or artificial materials 00:07:26
they are artificial materials 00:07:28
because paper is artificial 00:07:33
and rubber too 00:07:34
well 00:07:36
now we will see which one 00:07:38
which ones are 00:07:41
the properties 00:07:42
which one has more mass 00:07:45
which one is heavy 00:07:48
which one has more mass 00:07:51
The rubber has more mass. 00:07:53
And which one has more volume? 00:07:56
Which one occupies more space? 00:07:59
Yes, the paper boat has more volume. 00:08:01
So, although the rubber is smaller, it has more mass than the paper boat. 00:08:05
And the paper boat has more volume because it occupies more space. 00:08:12
now we will see the states of matter 00:08:18
there are three states of matter 00:08:23
solid, liquid and gas 00:08:26
solid like an apple 00:08:31
which is solid 00:08:36
liquid like this orange juice 00:08:38
and gas like smoke 00:08:42
and the characteristics of these states are 00:08:46
the first one, solid. 00:08:52
If you look at this table, 00:08:56
you see that solids have always the same shape 00:08:59
like this pencil case. 00:09:03
My pencil case has always the same shape. 00:09:06
It doesn't become bigger or smaller. 00:09:10
It's always the same. 00:09:14
and they occupy the same space okay then liquids liquids take the shape of the 00:09:15
container okay like this this water takes the shape of this glass and 00:09:31
liquids have the same volume they don't change although you change the container 00:09:45
the volume is always the same. Gas. Gas has the shape of the container and it occupies the space 00:09:51
of the container. For example, the air in this room takes the shape of the room, which is a square, 00:10:03
And it also occupies the space of the room. 00:10:13
What happens if we open the window? 00:10:20
The air goes out as well. 00:10:23
It goes out of the window as well. 00:10:27
It spreads. 00:10:30
So gas fills the space of the container. 00:10:32
Okay? 00:10:37
Now, we will see an experiment to see that liquid takes the shape of the container and the volume doesn't change. 00:10:37
Look, there were 100 milliliters and the water is taking the shape of the different types of containers. 00:10:52
the bottle the glass and now this long tube that although it's thinner it it is always the same 00:11:17
volume you will see the water is has the same volume 100 milliliters the same as the ones we 00:11:30
had before, the original volume. So, liquid changes and takes the shape of the different 00:11:41
containers where you pour it, but the volume is always the same, although you change the container. 00:11:49
What about gas? Let's see gas. There is another experiment to prove that gas has a volume and a 00:11:56
For example, we are going to take a balloon and first the balloon is empty, like this one. 00:12:06
But what happens if we blow the balloon? 00:12:17
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. 00:12:20
now let's see and let's prove that gas has a mass in the video on the right there are two balloons 00:12:33
one is empty and the other is full and you will see that the balloon which is full 00:12:45
has more mass than the empty balloon it is heavier it has more mass so that's why gas 00:12:52
which is there inside, has a volume and a mass. Today we learned a few new words. The first one 00:13:04
is container, which is a recipient where we keep things and put things inside. 00:13:17
Full and empty. You can see the first container is full of popcorn and the second container 00:13:25
is empty because there isn't popcorn and the last one balloon you can see the picture of a balloon 00:13:33
and now you can take your little notebook write these new words and draw pictures 00:13:44
about them okay i hope you like this session see you later alligators take care 00:13:51
