Vídeo explicativo de los insectos para Natural Science, en inglés y castellano.
Hello boys and girls, hello my friends. How are you today? Are you fine? I'm very fine too.
00:00:05
Okay, let's talk about today about the last group of animals we're gonna see in natural science
00:00:14
because next unit will be about plants. And these are, these animals are insects, okay? Insects.
00:00:21
they have a characteristic in common like the previous groups of animals we've seen
00:00:30
but they are very different too so let's see some characteristics about them and let's
00:00:37
learn a little about about them too, ok?
00:00:44
What's up guys?
00:00:48
Very good, here I am again.
00:00:50
This time to talk to you about insects, okay?
00:00:53
group of animals is very different from the ones we have seen before, okay, so far, but they have some
00:00:57
characteristics in common that we are also going to see, then, well, we are going to see some of those characteristics
00:01:07
now with the help of the presentation, and I hope you enjoy it and learn a lot, okay?
00:01:14
Okay, let's begin, come on.
00:01:20
the first difference with the rest of animals we've seen okay insects are invertebrates they
00:01:22
haven't got a backbone repeat please after me insects are invertebrates they haven't got a
00:01:31
backbone okay they have no skeleton okay the inside the bodies maybe some of them they have
00:01:44
like a soft like a hard shell around like a crocodile or another grasshoppers or it seems
00:01:54
that they have a hard shell out of the of their bodies but they have no skeleton inside their
00:02:03
bodies the backbone it means the okay this this bone okay from our neck to our to our low back
00:02:11
This is the backbone, it's made of vertebrates, ok?
00:02:22
So, this is the main characteristic that they have different than the rest of animals, ok?
00:02:29
Bueno, como veis, la principal diferencia es que los insectos son invertebrados.
00:02:40
No tienen backbone, significa la columna vertebral.
00:02:45
Lo que quiere decir es que, bueno, pues algunos de ellos tienen una especie de caparazón externo, un exoesqueleto que parecen que están duros como las cucarachas, como los saltamontes, pero no se puede considerar un esqueleto. El esqueleto debe ser interno y no es el caso, ¿vale?
00:02:48
Well, let's continue then.
00:03:11
Insects are oviparous.
00:03:17
Repeat please.
00:03:20
Insects are oviparous.
00:03:21
Ok, it's easy, ok?
00:03:23
We know what the oviparous is, so in this case the insects lay a lot of eggs at once.
00:03:29
They lay anywhere and sometimes on their bodies, sometimes in any place.
00:03:37
little insects were born very, very fast, ok? So they can lay a lot of eggs and they can
00:03:46
born very fast too, ok?
00:03:56
Well, they are oviparous, right? The insects too, and in this case they can lay a lot
00:03:59
of eggs at the same time and the insects are born very fast, because they are very small.
00:04:06
So, well, as you can see, they can put a lot, we don't do that, so it's very easy for them to expand, right?
00:04:11
It's very easy for them to multiply.
00:04:20
Next.
00:04:22
Insects are small.
00:04:24
Repeat, please.
00:04:27
Insects are small.
00:04:28
Okay, they are small if we compare with the rest of animals that we've seen, okay?
00:04:32
Because, for example, we talk about elephants or we talked about whales or fish, any kind of fish. Or we talk about eagles, birds, bigger birds.
00:04:37
So, in this case they are very very small, most of them we can have it on our hand, because maybe the smallest one is the ant,
00:04:52
it could be like this, and the bigger one could be the grasshopper, the mantis, that can be like this size, more or less.
00:05:06
But, in comparison with the rest of the animals we've seen, they are small.
00:05:17
Well, they are small, the insects are small.
00:05:23
It is true that there are some insects that are very big, but of course,
00:05:27
comparing it with the animals we have seen so far, they are small.
00:05:30
They can be the size of an ant, as it can be this big,
00:05:36
or the size of a mantis or a mantis that can occupy almost the palm of our hand, okay?
00:05:41
But let's go, in comparison with the rest they are small.
00:05:48
Insects have got six legs.
00:05:53
Repeat please after me.
00:05:56
Insects have got six legs.
00:05:58
Always, always they have got six legs.
00:06:04
If we find another thing, another animal that we can think that it's an insect, that it has eight legs, like for example spiders, they are not insects, okay?
00:06:07
They belong to a different group.
00:06:19
For example, in this case, there are a lot of insects that have six legs, like ants, grasshoppers, ladybirds, butterflies.
00:06:23
all of them has six legs.
00:06:34
But for example, we talk about the spiders,
00:06:36
they belong to another group, ¿ok?
00:06:38
Bueno, pues los insectos tienen seis patas, siempre, ¿vale?
00:06:41
Si nosotros vemos algún bicho que pueda tener ocho,
00:06:46
como pueden ser las arañas,
00:06:49
ya no pertenecen al grupo de los insectos, ¿vale?
00:06:51
Por el simple hecho de tener ocho patas.
00:06:53
Entonces, pues, pertenecen al grupo de los arácnidos,
00:06:55
que es un grupo aparte, que no vamos a estudiar este año.
00:06:59
In this group of insects with six legs, well, there are a lot, okay?
00:07:02
Well, what I have told you, up to now we have put examples,
00:07:07
well, the mantis, the saltamontes, the ants, the flies, mosquitos,
00:07:11
mariquitas, butterflies, a lot, okay?
00:07:18
There are many, many insects that have six legs and that serve as an example.
00:07:23
Ok, some insects can fly, repeat please, some insects can fly.
00:07:32
Insects that can fly, flies, mosquitos, ladybirds, butterflies, ok, and there are some insects
00:07:43
that can't fly, like ants, crocoches, grasshoppers, they jump but they don't fly.
00:07:54
Okay, so they can fly and sometimes they can't fly.
00:08:04
Bueno, como veis, insectos que pueden volar.
00:08:11
Por ejemplo, los mosquitos, las moscas, mariquitas, mariposas, ¿vale?
00:08:14
Porque tienen alas.
00:08:21
Pero hay otros insectos que no pueden volar.
00:08:23
Cucarachas, hormigas, he puesto el ejemplo del saltamontes, que en este caso salta, pero no vuela, ¿vale?
00:08:25
porque no tienen alas
00:08:32
pero hay muchos que sí que pueden
00:08:34
que pueden volar
00:08:36
ok
00:08:37
and this is the end of this presentation
00:08:39
so I hope you find it useful
00:08:41
