Hello everybody, this is a video in which I am going to show you how to do the natural science experiment

2
00:00:05,330 --> 00:00:12,050
because some of you wrote an email to me asking me about the experiment

3
00:00:12,050 --> 00:00:15,130
because you don't know how to do it in a proper way

4
00:00:15,130 --> 00:00:21,989
and in the video, in the meeting that we had today, you also were in trouble

5
00:00:21,989 --> 00:00:29,469
so it's really really easy but maybe you are not doing it in the correct way

6
00:00:29,469 --> 00:00:50,530
So you will see how to do it and I hope you will do amazing things to me and you will record amazing videos for me. So what you will need is, I'm going to move just the computer, right? So you will need a couple of glasses or a glass, right?

7
00:00:50,530 --> 00:01:09,129
And you will need also some drawings, right? Like this one. So what you have to do is very easy. If you put behind the glass the arrow which is following a direction, that direction will change.

8
00:01:09,129 --> 00:01:27,510
Can you see it? It's a direction, a different one. If you put it like this, you won't see it, right? So you just have to move it little by little till you find the correct position, right? As you can see, that could be the perfect position.

9
00:01:27,510 --> 00:01:45,870
If we put it in a different kind of glass, we will see that maybe it's not working or maybe you will see different things, but in this case, the direction of the arrow is changing, right?

10
00:01:45,870 --> 00:01:54,510
I have here a guy saying hello to everybody and if I put it behind the

11
00:01:54,510 --> 00:01:59,989
glass you will see at that place and that's more in this position you will

12
00:01:59,989 --> 00:02:06,109
see that the guy is upside down and you see it like a Modena when we have

13
00:02:06,109 --> 00:02:11,770
meetings right but if I continue moving it it just changed the direction of the

14
00:02:11,770 --> 00:02:25,469
hand, right? Yes, he has a different hand, right? He's raising a different hand and we

15
00:02:25,469 --> 00:02:39,110
can observe here the same, that he, the guy, is upside down, right? And let's go

16
00:02:39,110 --> 00:02:45,610
into some... that is magic, right? Look, I have a number 9 and can you see the

17
00:02:45,610 --> 00:02:55,800
number nine because now it's a number oh it's not a number it's a number six

18
00:02:55,800 --> 00:03:08,680
right can you see number six and here I have a number nine or a number six right

19
00:03:08,680 --> 00:03:23,599
and we will have sorry can be an a I know right so that's the experiment you

20
00:03:23,599 --> 00:03:30,580
have to do the one with a pencil or the pen in this case a pen it's very simple

21
00:03:30,580 --> 00:03:37,000
look we can see that if is that there is following this direction it doesn't

22
00:03:37,000 --> 00:03:46,939
change but when we move it we can see we can observe what we want to learn in

23
00:03:46,939 --> 00:03:53,879
this unit which are the concepts the concepts of reflection and reflection

24
00:03:53,879 --> 00:04:00,699
right and that's all this is a video I would like to see your videos please

25
00:04:00,699 --> 00:04:10,060
send send the videos to the to the different folders we have and have a nice week bye bye
