1 00:00:05,549 --> 00:00:13,390 Hello boys and girls, hello my friends. How are you today? Are you fine? I'm very fine too. 2 00:00:14,269 --> 00:00:21,129 Okay, let's talk about today about the last group of animals we're gonna see in natural science 3 00:00:21,129 --> 00:00:30,429 because next unit will be about plants. And these are, these animals are insects, okay? Insects. 4 00:00:30,429 --> 00:00:37,509 they have a characteristic in common like the previous groups of animals we've seen 5 00:00:37,509 --> 00:00:44,350 but they are very different too so let's see some characteristics about them and let's 6 00:00:44,350 --> 00:00:48,630 learn a little about about them too, ok? 7 00:00:48,630 --> 00:00:50,630 What's up guys? 8 00:00:50,630 --> 00:00:53,630 Very good, here I am again. 9 00:00:53,630 --> 00:00:57,850 This time to talk to you about insects, okay? 10 00:00:57,850 --> 00:01:07,510 group of animals is very different from the ones we have seen before, okay, so far, but they have some 11 00:01:07,510 --> 00:01:14,030 characteristics in common that we are also going to see, then, well, we are going to see some of those characteristics 12 00:01:14,030 --> 00:01:19,689 now with the help of the presentation, and I hope you enjoy it and learn a lot, okay? 13 00:01:20,569 --> 00:01:22,250 Okay, let's begin, come on. 14 00:01:22,250 --> 00:01:31,090 the first difference with the rest of animals we've seen okay insects are invertebrates they 15 00:01:31,090 --> 00:01:44,540 haven't got a backbone repeat please after me insects are invertebrates they haven't got a 16 00:01:44,540 --> 00:01:54,500 backbone okay they have no skeleton okay the inside the bodies maybe some of them they have 17 00:01:54,500 --> 00:02:03,459 like a soft like a hard shell around like a crocodile or another grasshoppers or it seems 18 00:02:03,459 --> 00:02:11,280 that they have a hard shell out of the of their bodies but they have no skeleton inside their 19 00:02:11,280 --> 00:02:22,520 bodies the backbone it means the okay this this bone okay from our neck to our to our low back 20 00:02:22,520 --> 00:02:28,599 This is the backbone, it's made of vertebrates, ok? 21 00:02:29,520 --> 00:02:39,139 So, this is the main characteristic that they have different than the rest of animals, ok? 22 00:02:40,159 --> 00:02:44,900 Bueno, como veis, la principal diferencia es que los insectos son invertebrados. 23 00:02:45,699 --> 00:02:48,460 No tienen backbone, significa la columna vertebral. 24 00:02:48,460 --> 00:03:11,960 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? 25 00:03:11,960 --> 00:03:17,599 Well, let's continue then. 26 00:03:17,599 --> 00:03:20,360 Insects are oviparous. 27 00:03:20,360 --> 00:03:21,740 Repeat please. 28 00:03:21,740 --> 00:03:23,099 Insects are oviparous. 29 00:03:23,099 --> 00:03:29,639 Ok, it's easy, ok? 30 00:03:29,639 --> 00:03:37,199 We know what the oviparous is, so in this case the insects lay a lot of eggs at once. 31 00:03:37,199 --> 00:03:46,159 They lay anywhere and sometimes on their bodies, sometimes in any place. 32 00:03:46,159 --> 00:03:56,719 little insects were born very, very fast, ok? So they can lay a lot of eggs and they can 33 00:03:56,719 --> 00:03:59,919 born very fast too, ok? 34 00:03:59,919 --> 00:04:06,080 Well, they are oviparous, right? The insects too, and in this case they can lay a lot 35 00:04:06,080 --> 00:04:11,319 of eggs at the same time and the insects are born very fast, because they are very small. 36 00:04:11,319 --> 00:04:19,720 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? 37 00:04:20,079 --> 00:04:21,439 It's very easy for them to multiply. 38 00:04:22,600 --> 00:04:23,079 Next. 39 00:04:24,560 --> 00:04:26,100 Insects are small. 40 00:04:27,519 --> 00:04:28,600 Repeat, please. 41 00:04:28,899 --> 00:04:30,459 Insects are small. 42 00:04:32,850 --> 00:04:37,209 Okay, they are small if we compare with the rest of animals that we've seen, okay? 43 00:04:37,209 --> 00:04:52,170 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. 44 00:04:52,170 --> 00:05:06,170 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, 45 00:05:06,170 --> 00:05:17,170 it could be like this, and the bigger one could be the grasshopper, the mantis, that can be like this size, more or less. 46 00:05:17,170 --> 00:05:23,170 But, in comparison with the rest of the animals we've seen, they are small. 47 00:05:23,170 --> 00:05:27,170 Well, they are small, the insects are small. 48 00:05:27,170 --> 00:05:30,170 It is true that there are some insects that are very big, but of course, 49 00:05:30,170 --> 00:05:36,170 comparing it with the animals we have seen so far, they are small. 50 00:05:36,170 --> 00:05:41,170 They can be the size of an ant, as it can be this big, 51 00:05:41,170 --> 00:05:48,610 or the size of a mantis or a mantis that can occupy almost the palm of our hand, okay? 52 00:05:48,610 --> 00:05:51,670 But let's go, in comparison with the rest they are small. 53 00:05:53,569 --> 00:05:56,009 Insects have got six legs. 54 00:05:56,930 --> 00:05:58,230 Repeat please after me. 55 00:05:58,569 --> 00:06:01,810 Insects have got six legs. 56 00:06:04,420 --> 00:06:07,019 Always, always they have got six legs. 57 00:06:07,019 --> 00:06:18,639 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? 58 00:06:19,000 --> 00:06:22,480 They belong to a different group. 59 00:06:23,060 --> 00:06:34,100 For example, in this case, there are a lot of insects that have six legs, like ants, grasshoppers, ladybirds, butterflies. 60 00:06:34,100 --> 00:06:36,699 all of them has six legs. 61 00:06:36,819 --> 00:06:38,519 But for example, we talk about the spiders, 62 00:06:38,699 --> 00:06:40,319 they belong to another group, ¿ok? 63 00:06:41,279 --> 00:06:45,800 Bueno, pues los insectos tienen seis patas, siempre, ¿vale? 64 00:06:46,079 --> 00:06:48,939 Si nosotros vemos algún bicho que pueda tener ocho, 65 00:06:49,019 --> 00:06:50,480 como pueden ser las arañas, 66 00:06:51,180 --> 00:06:53,360 ya no pertenecen al grupo de los insectos, ¿vale? 67 00:06:53,379 --> 00:06:54,920 Por el simple hecho de tener ocho patas. 68 00:06:55,920 --> 00:06:59,579 Entonces, pues, pertenecen al grupo de los arácnidos, 69 00:06:59,720 --> 00:07:02,300 que es un grupo aparte, que no vamos a estudiar este año. 70 00:07:02,300 --> 00:07:07,040 In this group of insects with six legs, well, there are a lot, okay?
