In this case we are going to explain something about Scratch. 00:00:03
Scratch is a free graphical programming environment 00:00:09
that was developed by researchers at Massachusetts Institute of Technology 00:00:13
under the direction of Mr. Mitchell Mresnik. 00:00:20
It was designed to help children to express their ideas, creativity 00:00:25
And develop logical thinking skills by creating games and animations that can share. We can work in Scratch in a program which you can download, but you can also use the online version of this program. 00:00:31
So here we are going to use the outline. So this is the main screen in which you can see different parts. 00:01:00
Well, Scratch is a programming language, it's a high-level program language, and it's a programming, it's graphical, and it also uses different types of blocks. 00:01:17
As you can see here, you can do a new program, for example, and in a program you can have different things and different constants also. 00:01:42
This is the work, the full script and this is the stage. 00:02:12
So in the stage you can add different costumes using the library of Scratch to add some costumes. 00:02:19
And also you can change the scenery, so the first thing, here you have different, this 00:02:43
is the scenery and in the scenery for example you have different animals or so on, so you 00:03:02
can add a costume and then using the mouse you can change its position and also do it bigger or smaller 00:03:10
this is for the the background and here you can change the the background in your program 00:03:41
You can also upload it from your computer if you want as a graphic file, so the format that you can use is the GPA or PNG. 00:04:06
and each custom, here, have... well, this is the background 00:04:40
you can change, for example, in this case, you can change the scenery 00:05:08
for example using the library for backgrounds and you can also edit the 00:05:16
different pictures and as you can see here you can change it for example I 00:05:42
I want to... you can use this tool to change something, to change your scenario or to change, for example, to change one of these, one custom, you can also change using these tools. 00:05:51
For example, I can change the color of the cat if you want. 00:06:49
And other characteristics of the costumes and also the background are sounds. 00:07:13
So you can use different sounds. 00:07:21
You can also upload from your computer and so on. 00:07:23
And the most important thing is obviously that these constants can be programmed by you and to do this you can have the different blocks in different categories. 00:07:29
For example, for control you have these categories. If you want to start something, some program, you always have to use this one. 00:07:58
For example, all of these blocks are for control. This is for example the green flag, you can also have different loops, this is a conditional for example. 00:08:15
wait something for something it's also important the the movements for example i can say that the 00:08:45
The cat moves 10 steps or do a rotation of 90 degrees or so on. 00:09:01
And also the appearance, so each costume has different, each character, each sprite has different costumes, as you can see here, so for example we decide that is the first costume. 00:09:28
You have different blocks for different things. Sensors, operations, variables. We are going to use different samples. This is just only the first day. 00:09:58
So as you can see, for example, here, 00:10:19
I can change the appearance of the cup 00:10:23
and also I move it. 00:10:27
The problem in this case is that the design of the program 00:10:33
is not very good at all. 00:10:37
It isn't good at all, but you can do it better. 00:10:40
Well, we are going to study, this is the first tutorial about Scratch. 00:10:55
What is Scratch? 00:12:19
Well, Scratch is a free graphical programming environment that was developed in Massachusetts 00:12:20
institute of technology to improve the creativity in our children and it can also be a very 00:12:29
they can also work in a share sharing their their work so it's very interesting 00:12:43
the format of the scratch usually is xv2 but you can have another station different station 00:12:53
there are you can use it in an offline version or you can use the online version 00:13:05
the outline version is very easy to use and it's more or less the same 00:13:19
well this is a scratch and you have different parts as you can see 00:13:29
this is the main scenario and here you have the background and also one of the sprites 00:13:36
so if you want to to change for example the background you can do it the 00:13:48
background you can do it because the background is just a graphic you have a 00:14:03
a graphic background you can change the background uploaded a file that you can 00:14:14
have in your computer or using the library that you have in the in the 00:14:25
program in this case we are going to to use the the library for example 00:14:33
i have to choose this one so i have changed the snri 00:14:44
is the same for the different sprites there are a lot of them 00:14:52
so I can I can change for example hearing things you can also change the the size of your of your 00:14:59
sprites using these tools and change the sprite and also undo this sprite smaller 00:15:24
well each sprite and also the scenery has three main characteristics 00:16:01
which are sounds that you can also upload from your computer if you want 00:16:11
customs which is difference appears and you can change it if you want for 00:16:23
example you can edit it this one in this case for example I am going to change 00:16:29
something or for example I can change the year I can also change the year for 00:16:46
example and finally you have programs in this case for example well it's 00:17:50
It's important that you know the coordinates of each object of this sprite here, that you 00:18:03
can see here the X and I are here and you can know it. 00:18:17
So the programs, if you want to do a program, you can have different blocks because Scratch 00:18:26
be programming using this block and they are you can get the difference block in 00:18:45
its category category for example here you have the block that can that can 00:18:56
start this program you can also have movements if you want or change the 00:19:10
appearance or sounds or you can also have a pencil sensors operators and 00:19:31
mathematical operation variables so you can do different programs for different 00:19:55
objects for example in this case I can also I can also change for example the 00:20:11
the appearance so the result you can see the result here it is very easy and we 00:20:34
develop all these contacts deeply but is the first tutorial so the main idea is 00:21:10
that you you do your your work familiar if you want to to save obviously you can 00:21:21
save in your well this is how you have saved your your work and and then you 00:21:31
can also have a I think it's better if the version online but you need to 00:22:39
register firstly so this is the this is a problem sometimes because you haven't 00:22:49
got any email and you need an email to do this well the the direction is scratch edu meet 00:23:00
if you have an account you can use your user number and your password and then here you 00:23:38
can explore you can do research about what other people have created or you go 00:24:45
to create in your in your account your brain is similar that we have already 00:24:57
explained because it's the same here you have the sprite you can add a sprite 00:25:08
here for example balloon so now we have two sprites and each have the codes the 00:25:29
customs and also the sounds the customs in the in this case can be changed easily 00:25:43
for example as you can see here from have changed the appearance also the sounds 00:25:57
and you can use the libraries and obviously the code in this case I have 00:26:47
difference for example this is our also the the SNRV and it is more or less the 00:27:01
same here you have different blocks so the first one obviously is this one 00:27:30
move, appearance and what you want to do 00:27:40
here the same, events, for example 00:28:31
and you can see what you have programming 00:29:33
here well it is important it's important for all of us that is the result we we 00:29:41
study this deeply but and I give you some some different exercises that can 00:30:11
and help you to training with Scratch. 00:30:21
It's very easy and I think it's very funny also. 00:30:28
So you can learn at the same time as you are playing. 00:30:38
And this is the first tutorial, so... 00:30:47
you 00:30:53
