Good morning, guys. I'm going to tell you what we're doing today for Natural Sciences. 00:00:06
So, as usual, we click in Mi Clase, we go to Content, we click on Natural Sciences Book, 00:00:12
go in into Unit 5 Forces, and today we are going to see magnetism. But we are not going to see it 00:00:20
the plus zone because it's too short i need to explain all the information so i will explain it 00:00:30
straight through the page okay so 00:00:39
And okay, so we're going to see about magnetism, okay, that we seen two days ago, we said that magnets have a force that is called magnetism, okay, so it can be, it may push or it may pull, okay, this is what we call attract or repel, all right. 00:01:00
and well magnetism remember that is a non-contact force because move objects without touching them 00:01:23
okay some of them are natural like the magnetite they are a mineral that we have seen in the 00:01:33
in the class i don't know if you remember that and but most of them are man-made man-made they 00:01:41
are made by men, OK? 00:01:49
So they are made from iron or steel, OK? 00:01:51
So this would be the typical magnet, all right? 00:01:57
So because of magnetism, so we have the typical nails moving 00:02:01
towards the magnet, or there is the repulsion strength, 00:02:07
There's a repulsion force that avoids these magnets to join, 00:02:13
or the magnets of the fridge, or this girl 00:02:19
with the typical game of fishing. 00:02:24
And also very important that we've seen in the past, 00:02:28
the needle on the compass always points north because 00:02:33
of the Earth magnetism, all right? 00:02:39
So how does a magnet work? Magnets create a magnetic field around them. 00:02:43
We cannot see it, okay, but there are attraction 00:02:51
and repulsion forces working. So this is a photo of a magnet 00:02:54
and iron fillings, okay. The iron fillings show us the magnetic 00:03:03
field. I will include a video about how a 00:03:09
magnetic field works, all right? And then, as we all know, because I'm sure you know it, 00:03:14
all magnets have two ends, all right? The north pole and the south pole. If we put north pole 00:03:24
and south pole in contact, they attract, okay? They attract each other, but same poles, 00:03:32
north and north or south and south they repel all right this is very important 00:03:40
okay so in this case if there are different poles or opposite poles they attract each other 00:03:47
if it's the same poles they repel each other all right in espanol 00:03:53
magnetism is a force of no contact of agreement because it moves objects without touching them we have 00:04:10
magnets that are natural that are minerals like the magnet that when we were seeing the 00:04:22
minerals we saw a magnet in class and we also have those that are man-made that are made by 00:04:27
man agree that they are artificial and that they are usually made of iron or 00:04:33
steel according to magnetism makes the nails stick to the magnet or that 00:04:38
the child cannot join these two magnets that I cannot join these two 00:04:47
magnets because there is a force of repulsion between them or the magnets of the 00:04:54
fridge or the magnets of this typical game that is to fish that there is a magnet 00:04:59
in the rod and a magnet in the fish and then you have to lift the fish without touching it with 00:05:05
your hands but the example of the compass is also very important, because the 00:05:12
needle of the compass always points to the north because it is attracted by the magnetic north of 00:05:18
the earth okay it is the magnetism of the earth ok that the earth has magnetism 00:05:24
also good and then let's see how it works 00:05:30
a magnetic field 00:05:34
because magnets create a magnetic field that is the magnetic field is a 00:05:37
magnetic field that cannot be seen however there is an experiment that 00:05:42
consists of rubbing iron filings that are these iron fillings iron fillings around we put 00:05:48
the iron filings around the magnet and we are seeing how the filings are arranged 00:05:56
because they are always arranged in a way with a kind of drawing of agreement this I am going to add 00:06:05
a video so that you can see how a magnetic field is I am going to put a youtube video so that 00:06:11
you see it okay and well and the last thing because we always know that we already know for sure 00:06:17
most of the magnets always have a north pole and a south pole and it is something curious I did not 00:06:23
explain it in English because if you and a magnet that has a north pole and a south pole you split it in half 00:06:30
because what we get is to have two magnets with a north pole and a south pole, that is, a north pole is always 00:06:36
genera un polo norte y un polo sur de acuerdo y entonces lo que sabemos pues 00:06:41
que dos y dos imanes que se acercan por los polos opuestos se atraen de a track 00:06:47
y dos imanes que se acercan por el mismo polo se repelen o sea que aquí hay un a 00:06:53
una fuerza de atracción y aquí hay una fuerza de repulsión ok this could be all 00:07:00
for the magnetism. So now we would go back and go to the plus zone, again go to 00:07:08
the digital activities and we would do activity three, drag the words, drag the 00:07:23
words to the sentences and 4. Are these sentences true or false? ¿De acuerdo? En la 3 tenemos que 00:07:32
mover las palabras para rellenar los huecos y en la 4 leer las frases y decir si son 00:07:42
verdaderas o falsas. Y esto sería todo por hoy. ¡Un saludo a todos! 00:07:50
