Hi everyone, we are going to continue with the Scratch project. First we are going to open again

2
00:00:06,290 --> 00:00:12,050
Scratch. We are going to close these two things that we don't need as we did before and we are

3
00:00:12,050 --> 00:00:21,730
going to upload the project that we saved before. There it is and there we are going to have what we

4
00:00:21,730 --> 00:00:27,890
did previously. The two characters and the code for the red and the blue spot. Now we are going to do

5
00:00:27,890 --> 00:00:34,729
do the difficult part which is to program the code to make the matter in

6
00:00:34,729 --> 00:00:41,149
this case water change to liquid solid or gas depending on the temperature okay

7
00:00:41,149 --> 00:00:45,829
the first that the first thing that we are going to do as we did before is to

8
00:00:45,829 --> 00:00:57,289
start with when we click on the green flag forever and inside forever we put

9
00:00:57,289 --> 00:01:08,870
conditionals if and we are going to do first is to say to the red point that if

10
00:01:08,870 --> 00:01:13,609
we touch it it has to increase temperature and to the red to the blue

11
00:01:13,609 --> 00:01:21,250
point that if we touch it it has to decrease temperature so this is if

12
00:01:21,250 --> 00:01:33,150
touching color blue and to get exactly this color we have to do it like this if

13
00:01:33,150 --> 00:01:41,689
touching color blue it change

14
00:01:41,689 --> 00:01:52,489
variable that we have to create to minus one because we want to decrease

15
00:01:52,489 --> 00:01:58,489
temperature. First we are going to create a variable that is going to cool

16
00:01:58,489 --> 00:02:08,810
temperature only for this object so change my temperature by minus one and

17
00:02:08,810 --> 00:02:36,889
And then again, if touching color red, and to get exactly the same color, first we click on red. And we look for it. If touching color red, again, change my variable, which is temperature, to plus one.

18
00:02:36,889 --> 00:02:43,770
okay that's for the colors to increase and decrease temperature then what we want to do

19
00:02:43,770 --> 00:02:52,250
is to say to the program that if the temperature is lower than zero it has to be ice solid if

20
00:02:52,250 --> 00:03:00,250
temperature is more than 100 degrees it has to be gas in this case the cloud and if the temperature

21
00:03:00,250 --> 00:03:10,810
is between 0 and 100 it has to be liquid, a drop of water. So if we are going to say

22
00:03:10,810 --> 00:03:30,990
again if temperature is less than zero and then we are going to say if temperature is

23
00:03:30,990 --> 00:03:40,389
less than zero, then it changes or switches to costume solid, the ice cubes.

24
00:03:40,389 --> 00:03:59,800
And again, if, we have to put it there, if, we need another operator, if temperature is

25
00:03:59,800 --> 00:04:12,060
more than 100 I want to switch my costume to gas the cloud and finally we

26
00:04:12,060 --> 00:04:24,839
are going to say that if and we need two operators here so if first temperature

27
00:04:24,839 --> 00:04:41,180
is more than zero and less than 100 so this is more than zero and less than 100

28
00:04:41,180 --> 00:04:59,680
the temperature in both gaps it has to change to costume water okay drop of water so we are going

29
00:04:59,680 --> 00:05:06,800
to see that if it touches you see it increases temperature and it changes to well if we make

30
00:05:06,800 --> 00:05:13,519
it bigger we can see it better now it's color blue and if we touch the cloud it

31
00:05:13,519 --> 00:05:19,100
should decrease temperature and it happens because it's less than 100 it

32
00:05:19,100 --> 00:05:23,079
changes to liquid and if we continue touching the drop of water when it's

33
00:05:23,079 --> 00:05:29,540
less than zero it will be ice that's it and if we change to red the same the

34
00:05:29,540 --> 00:05:36,579
temperature increases and it changes the different states of water and that's all

35
00:05:36,579 --> 00:05:46,779
we can save again the project save to your computer and so we have it and you

36
00:05:46,779 --> 00:05:55,980
can share it with your teacher as he or she likes bye bye I hope you like it
