Lesson video

Hi, everyone.

Welcome to today's science lesson.

I'm Miss Harris, and today we are going to be learning about how to look after our ears.

They're a very important part of our body and we need to look after them, so we're going to find out how.

Let's see what else we're doing.

We are going to be recapping what sound is, we are going to be looking at how we look after our ears, we're going to look at the parts of our ears, looking after our ears, and then we've got our end of lesson quiz.

You will need an exercise book or a sheet of paper, but you're more likely going to need a sheet of paper, so make sure that you can pull one out of your exercise book so it's ready.

You would need a pencil, a coloured pencil, and your brain.

So we are scientists in today's lesson, so let's recap what a scientist is.

A scientist is a person who studies the world around us, including the living and non-living things.

Should we do that again? A person who studies the world around us, including the living and non-living things.

Let's do our Star Words.

These are the important words we're going to learn this lesson.

Ready? Sound.

Safety.

Careful.

Damage.

Quiet.

Loud.

Protect.

Volume.

Great job.

Now, what is sound? Can you remember what sound is? Hmm, let's have a look.

So sound is a mm of vibrations that mm through the mm.

Can you pause the video and fill in the gaps, writing this down on your piece of paper? Remember to look at the pictures above the gaps to help you remember.

Pause the video, have a go at that now.

Well done.

Let's check what our answers are.

So pick up your coloured pencil and get ready to tick or fix.

Ticking means you're checking that it's right because you've got it right, and fixing means you're just going to put a nice, neat line through it and write it above it.

So sound is a wave of vibrations that travel through the air.

Give yourself a tick for wave, give yourself a tick for travel, and give yourself a tick for air.

If you didn't get those right, don't worry.

Just put a nice, neat line and write correct the word there.

If you need to do that, you can pause the video now.

Well down.

So sounds are made when an object vibrates, and when it vibrates it makes a sound.

So let's have a look.

When a guitar makes a sound, it sends an invisible wave into our ears.

You're right.

And this then sends invisible messages to our brain to help us remember the sound and listen to the sound.

And our brain can remember that sound so that we know what the sound is.

So if someone's whistling and I hear the sound but I can't see it, I know that someone is whistling, okay? Now I'm going to show you how we are going to structure our piece of paper today, because we're going to make a poster all about how to look after our ears.

So let's see how we're going to set up our piece of paper.

Okay, to fold our sheet of paper into three parts, what we are going to do is we are going to fold our sheet so that we've got two equal parts like this, and then make a crease.

We are then going to turn it and we're going to fold the other sheet back again and fold like this.

Then we have got three parts.

Now, my parts are not even but that doesn't matter too much.

So we're going to put that to the side for a moment just while we wait till we need to do some writing, so just put it to the side for now.

So this is the anatomy of our ear.

That means what our ear looks like inside our brain.

So this part is inside our head and you can see here the ear and then that parts the bit that's inside that we can't see, because I can't see it.

Can you see it? No.

So this is our ear.

Our ears are really important, so we have to make sure we look after them.

I'm going to show you the different parts of ears and how we're going to write it on our piece of paper.

So this part in this pink box, this is our outer ear.

What's it called? Our.

It's the part on the outside.

You can see it.

Look, I've got this part of my ear here.

It's our outer ear.

Now this part of our ear, we can get to it really easily.

I've got an earring in my outer ear.

You need to make sure that we clean the outside of our ear by washing regularly.

So when I'm in the shower or having a bath, I need to make sure that I clean my ears at the back and at the front and then in between all the gaps.

It's really important that they are really clean so that our ears stay healthy.

We then got this part in the blue box called the middle ear.

What's it called, the? The middle ear, well done.

This part of our ear you can see is almost like a little tunnel.

It's called our ear canal.

What's it called? Good, so you can see it goes in this part, the hole in our ear.

We must not put things inside our ear.

Now, you might put a little cotton bud in your ear to clean it, but your grownup might help you do that so you don't push it too far.

It's important that we don't put things inside our ear, including our fingers, because our finger's covered in germs and we don't want to get our ear dirty inside.

But we don't want to put things in there because they might get stuck.

So we have to make sure we do not put things inside our middle ear.

Inside our? Good.

And the last part of our ear, this is the most important part because here we've got something called our eardrum.

What's it called, our? So it's not a little drum inside our ear, but it acts like one.

It's a little muscle, and lots of muscles inside our ear help us to hear sounds.

And these muscles and all of the parts of our ear send the messages to our brain to help us hear and remember sounds.

So it's really important that we don't have really loud volume on our videos when we're listening to headphones or when we're listening to music, because this might damage our eardrum.

And your parent might say, "You're going to hurt your ear.

Can you turn it down please?", or your carer, because it's important that we don't damage the inside of our ear because the sound travels in through our ear canal into those parts of our inner ear, and we must look after them.

So now I'm going to show you how to write down the three parts of our ear.

We're then going to write down some facts about how to look after each part of our ear that we just learned about.

So let's take a look at how we can label the three parts of our ear.

Now let's write the names of the three parts.

What we can do is we can write.

Sorry, I'm just going to turn my camera slightly.

So this first part is going to be about my outer ear.

So I'm going to write the word outer and ear.

I can then later on do my writing on this side about my outer ear.

I've then got my middle ear.

And lastly, I have got my inner ear.

So I can do my writing here, here, and here.

Great.

So we have just written down the three parts of our ears.

Now we are going to write some sentences now in each section of our sheet of paper.

You are going to write this sentence down and fill in the gaps.

So let's read it together.

Can you follow with your finger? To look after our mm, we must keep it mm by mm regularly.

So we've got the three words at the bottom.

We've got outer, washing, and clean.

So look at this picture.

Can you remember which part of our ear is this? To look after our mm ear.

So which part? We must keep it by regularly.

Did you like those actions? So pause the video and write this down in the first part of your sheet.

Well done.

Let's check our sentences.

So it will look like this.

To look after our outer ear, we must keep it clean by washing regularly.

Well done.

Now the next one.

This is the next part of our sheet.

To look after our mm ear, so have a think about which part of our ear that is, we must not mm things our ear.

It could get.

Okay? So we've got the words inside, put, middle, and stuck.

I would like you to pause the video and write this down on the middle part of our sheet and fill in the gaps.

Have a go at that now.

Great work.

Let's check our answers.

So to look after our middle ear, we must not put things inside our ears.

It could get stuck.

Now the final part of our ear.

To look after our mm, we must turn the mm down when listening to sounds.

So we've got the two words inner and volume.

Where do they go in the sentence? Can you pause the video and write that down now? Well done.

Let's check.

To look after our inner ear, We must turn the volume down when listening to sounds.

Great work.

Your poster is now complete.

You can put your poster somewhere in your house to help your family look after their ears as well.

Now, if you would like to share your work with us, you can ask your parent or carer to share a photo of it on Twitter using the tag @OakNational and the hashtag #LearnWithOak.

I hope you have a wonderful rest of your day and I will see you next time.

Bye.
