1 00:00:00,000 --> 00:00:05,440 Good morning! This is a video in which we are going to learn about hearing, right? 2 00:00:05,860 --> 00:00:08,859 So, what are the organs of hearing? 3 00:00:09,660 --> 00:00:14,820 Obviously, the organs of hearing are the ears, right? 4 00:00:15,240 --> 00:00:18,739 Our ears are divided into three parts. 5 00:00:19,219 --> 00:00:24,019 The outer ear, the middle ear, and the inner ear. 6 00:00:24,199 --> 00:00:27,839 But, do you know what earwax is? 7 00:00:27,839 --> 00:00:33,920 Earwax is a sticky substance that protects our ears 8 00:00:33,920 --> 00:00:37,759 Because our ears are really, really, really delicate, right? 9 00:00:38,079 --> 00:00:41,780 And earwax protects them from dust and infections 10 00:00:41,780 --> 00:00:44,920 So let's go and read our book 11 00:00:44,920 --> 00:00:48,320 And we will learn more about hearing and our ears 12 00:00:48,320 --> 00:00:49,880 Read with me, please 13 00:00:49,880 --> 00:00:50,659 Ears 14 00:00:50,659 --> 00:00:53,479 Your ears are the organs of hearing 15 00:00:53,479 --> 00:00:56,539 And the ear has three parts that you know 16 00:00:56,539 --> 00:01:01,539 The outer ear, the middle ear, and the inner ear. 17 00:01:02,200 --> 00:01:06,700 And as you know, already know, ears are really delicate. 18 00:01:08,420 --> 00:01:14,120 Earwax is a sticky substance that protects our ears from dust and infections. 19 00:01:14,620 --> 00:01:17,640 So can you repeat with me the three parts of our ears? 20 00:01:18,560 --> 00:01:23,700 Outer ear, middle ear, and inner ear, right? 21 00:01:23,700 --> 00:01:26,400 Where is earwax? 22 00:01:26,540 --> 00:01:29,760 It's inside your ear canal, right? 23 00:01:31,920 --> 00:01:33,180 Can you see here the canal? 24 00:01:33,780 --> 00:01:36,060 So the earwax is on there. 25 00:01:36,640 --> 00:01:38,599 And the eardrum, what's that? 26 00:01:39,700 --> 00:01:41,840 Where do we have our eardrum? 27 00:01:42,480 --> 00:01:48,099 We need to know about it because we already have learned the different parts that our ears have, 28 00:01:48,099 --> 00:01:57,540 which are the outer ear, very good, the middle ear and the inner ear. 29 00:01:57,540 --> 00:02:02,500 But we need to know how do we hear things. 30 00:02:03,000 --> 00:02:04,040 How do we hear things? 31 00:02:04,920 --> 00:02:05,340 Right. 32 00:02:05,540 --> 00:02:13,819 The first step is when the sound waves enter through the outer ear, right? 33 00:02:14,360 --> 00:02:22,319 And that waves hit the eardrum and it vibrates, right? 34 00:02:22,319 --> 00:02:28,599 The vibration makes the liquid that we have in the inner ear to move 35 00:02:28,599 --> 00:02:34,419 and it sends signals to the brain, to our brain. 36 00:02:34,819 --> 00:02:42,300 Our brain reads these signals and tells you what you are hearing. 37 00:02:42,819 --> 00:02:47,699 We're going to have a look on this picture that we have on the book. 38 00:02:47,699 --> 00:02:57,360 So the first step is when the sound waves enter through the outer ear, right? 39 00:02:57,500 --> 00:03:05,060 And they travel through the canal and they hit the eardrum, our nostro tympanum, right? 40 00:03:05,060 --> 00:03:08,560 They hit the eardrum, right? 41 00:03:08,800 --> 00:03:16,939 And it sends signals to the brain, to our brain. 42 00:03:17,319 --> 00:03:26,180 And our brain, which is really, really clear, reads the signals and tells us what we are hearing. 43 00:03:26,740 --> 00:03:29,300 It's quite interesting, isn't it? 44 00:03:29,300 --> 00:03:36,199 So, now we are going to see some exercises to practice about it 45 00:03:36,199 --> 00:03:43,039 What I want you to do is first, you have to draw our ear and the different parts 46 00:03:43,039 --> 00:03:49,300 The outer ear, the middle ear and the inner ear with a canal and the eardrum, right? 47 00:03:49,599 --> 00:03:56,300 Second, what you are going to do is you are going to read the book again, right? 48 00:03:56,300 --> 00:04:04,639 and we are going to do exercises one for instance once look around which objects 49 00:04:04,639 --> 00:04:10,639 make sounds let's gonna do it all together which objects make sounds right 50 00:04:10,639 --> 00:04:18,300 look I have here my mobile phone and my mobile phone make sounds because when 51 00:04:18,300 --> 00:04:24,259 someone calls me it's gonna make a sound right what else can you please tell me 52 00:04:24,259 --> 00:04:27,879 which objects make sounds around you, right? 53 00:04:28,120 --> 00:04:30,860 I just need three objects, right? 54 00:04:30,959 --> 00:04:34,839 And you don't have to copy the exercise. 55 00:04:35,079 --> 00:04:39,639 You just have to write one page 13, right? 56 00:04:39,740 --> 00:04:40,959 And answer the question. 57 00:04:42,220 --> 00:04:47,759 Second, which organ reads signals from your eyes and ears? 58 00:04:48,199 --> 00:04:50,800 It's an organ that is really, really, really clever. 59 00:04:51,259 --> 00:04:52,439 And it's really important. 60 00:04:52,920 --> 00:04:54,100 I can give you more clues. 61 00:04:54,259 --> 00:05:01,939 right so you are going to do the exercise one the exercise two right and the exercise three 62 00:05:02,660 --> 00:05:09,779 how do sound waves travel order the words and i'm gonna give you another clue right 63 00:05:09,779 --> 00:05:16,819 if you come here and read it again or you're listening again to my video you will find that 64 00:05:16,819 --> 00:05:26,740 there are some words that are gonna give you the key, right? Perfect! So that's all related to 65 00:05:26,740 --> 00:05:34,339 hearing. We will see some videos related to the other senses that we have to learn and other parts 66 00:05:34,339 --> 00:05:43,060 of our body, right? But this is all for the moment and I will send you more videos. Bye bye! Take care!
