Lesson video

Hi there, I'm Miss Harris and welcome to today's Geography lesson.

We are starting our new unit of work, called Oceans and Seas.

What's it called? Good, we are going to be learning about the five oceans that are on our planet.

They're in different parts all over our Earth and they're different sizes.

So today we're going to be looking at, where they are on a map, and we're going to be looking at the size of each ocean.

What is an ocean, is today's focus.

We are going to be introducing the new unit, looking at what an ocean is, the definition of an ocean.

How many oceans there are? The size of each ocean, and the temperature of each ocean.

That means how warm or cold each ocean is.

In this unit of work, we are going to be geographers.

Do you know what a geographer is? You don't, that's okay, let's have a look.

So, a geographer is a special type of scientist, who studies the earth, the land, and the people.

Now, I've got some actions to help us remember this.

So we could say, geographers are special types of scientists who study the earth, the land, and the people, you can put yourself, because you are a person, okay? We should we do that together.

So, a geographer is a, special type of, scientist, good who studies the, earth the land and the, people well done, good remembering, Okay, in this lesson, you will need an exercise book or a piece of paper, a pencil, a coloured pencil or pen, and most importantly, you are going to need your brain.

So if you haven't got your brain, can you go and get it for me? Because you're going to need it in today's lesson.

So, we're going to take a look at our star words, these are the important words that we are going to be using throughout this lesson.

So it's important, we practise saying them because saying them, it's going to help them, stay in our brain for longer.

So, we're going to do some actions.

So we're going to do something called, my turn your turn.

So when I point at you, that's when you're going to tell your screen or your tablet, okay? So, oceans, , good.

Pacific, Atlantic, Indian, Southern, Arctic, continent.

Good, let's say them with some actions.

Ocean, your turn good.

Pacific, Atlantic, good.

Indian, Southern, Arctic, good.

Continent, good, okay.

Now let's have a look at the next part of our lesson.

So, our planet, we can see here.

Our Earth, it's called Earth.

It's called Planet Earth, what's it called? Planet Earth is also known as the Blue Plant,.

Why do you think it's called the Blue Planet? So, it's called the Blue Planet because as you can see from this picture, the Earth is almost all covered by oceans.

70% of our Earth is covered by water.

So here, I have got my own inflatable planet, as you can see here.

And if I spin it around, you can see.

Look at this part, it's completely covered in oceans, the blue and you can see here.

We've got some continents, but there are a lot of water, there is a lot of water.

So, what is an ocean? Can you take 10 seconds to think about, what is an ocean? Take 10 seconds.

Have you got an answer? That's okay if you don't, we're going to look now.

So, an ocean, is a huge body of salt water.

That means the ocean is huge, and the water is really salty.

Can you use your finger to follow the words, as I read them, are you ready? You might want to read along with me.

An ocean, is a, huge body of salt water, good.

Should we do it one more time? Can you read it with me this time if you didn't that time? An ocean, is a huge body of salt water, well done.

And you can see, here is a picture of our ocean.

The oceans are huge, huge, and this is what they look like.

So, in your exercise book, or on a piece of paper, I would like you to write down this definition.

That means, what is an ocean? You're going to write down what it means, the definition.

And I'd like you to fill in the gaps because there's some words missing.

So, pick up your pencil and I'd like you to get started now.

Pause the video and have a go.

Great job, so now pick up your coloured pencil or pen, and we are going to do something called tick or fix.

That means, if you got it right, you're going to give yourself a tick.

And if you didn't get it right, that's okay, you're going to put a nice, neat line through it, and you're going to write the correct answer above it, okay? So let's have a look.

An, ocean, if you wrote ocean, give yourself a tick, we're going to fix at the end.

If you didn't write ocean, don't worry, we're going to do it in a moment.

So an ocean is a huge body of, salt, give yourself a tick, water, and don't forget that full stop at the end.

Now, if you've got some of those wrong, that's okay, you can pause the video now and make some corrections.

Okay now, on our Earth, on our planet, there are seven huge pieces of land called a continent.

A continent, is a large area of land, and you can see here, I've used this map, which shows the continents in different colours.

How many continents are there? Can you count the different colours? Ready, one, How many did you count? Seven, me too.

Now, we are going to be looking at, where the five oceans are in relation to the seven continents.

That means, which oceans are next to which continent? So we count where the continents are, so we have got, North America, South America, Europe, Africa, Asia, and Australia, Antarctica, down the bottom.

So, here's a picture of a map.

And you can see here, that I have got the oceans and the land.

The blue part represents the water, surrounding the land which is green.

The map shows the Earth as if it was flat, but our Earth in space is actually a sphere shape.

It's this type of shape, let me get my globe.

It's this shape, a sphere, like this.

But when we look at a map, we want to know where all of the continents, we want to know where lots of things are.

So we flatten our Earth, like this, and you can see it in this picture.

How many oceans are there in the world? Can you remember what I said at the start? There are five oceans, how many are there? Five oceans, good.

We're going to have a look at where they are on the map.

So let's look at the first one.

The first one is the Pacific Ocean.

My turn, Pacific Ocean, good.

So the Pacific Ocean, you can see, I've written it two times on the map, that's because as I said, the map is flat.

So it doesn't show you that actually when we look at our Earth, the Pacific Ocean, it's just one big ocean.

So let's have a look at my globe a bit more carefully.

So we can see here, this whole part of my globe is the Pacific Ocean.

But when it's on my map, it's almost like I've chopped it in half and opened it up.

And I've written here that this part is the Pacific Ocean, let's have a look.

So you can see on this side here, right here I've written it, which is here on my map.

And then if I spin it around this way, you can see I've written it on the other side, because this whole side of our Earth is the Pacific Ocean, because it's the biggest ocean.

Then, we have got the Atlantic Ocean, which the Atlantic Ocean on our globe goes all the way from the Arctic, oh sorry, you can't see me, up here, from the Arctic all the way down here, so this whole part.

Then we have got the Indian Ocean, which we can see on my map or my globe is here.

Then we have got the Arctic Ocean, which is at the top.

And lastly, we've got the Southern Ocean, which is at the bottom, which surrounds Antarctica, we know which is the coldest continent, okay? Now, I've mentioned this, that the Pacific Ocean is the largest ocean in the world.

What's the largest ocean? I didn't hear you, can you say it louder, the Pa? Good, the Pacific Ocean is the largest ocean in the world.

And we know that from looking at Miss Harris' globe, we can see it's huge, all this face here, it's really big.

Oh, my globe just fell on the floor.

Don't worry, we don't need it for now.

It's rolled away, that wouldn't happen in space.

Then we have got the Atlantic Ocean.

Now the Atlantic Ocean, is the second largest ocean, but it's only half the size of the Pacific, that just shows how big the Pacific Ocean is.

We've then got the Indian Ocean, which is the third largest ocean.

So, so far we've got the Pacific, then the Atlantic, and then the Indian Ocean.

Can you say that with me? Pacific, Atlantic, Indian Ocean, good job.

Then we've got the Southern Ocean, which is the second smallest ocean in the world.

It surrounds the Antarctica, which is the coldest continent.

It's home to penguins, blue whales, seals, and giant squids.

We've then got, I mean you can see here, it goes all the way around the continent.

Then we've got the Arctic Ocean.

Often the Arctic Ocean is completely covered in ice because it doesn't have any land underneath it like Antarctica does.

It's just a big sheet of ice on top of the water.

And it's got the smallest ocean in the world, and it's at the top of our Earth.

Now, I would like you to pick up your pencil, and you are going to order the oceans from the largest to the smallest.

From the, largest, good to the, smallest, good.

Now while you do that question, I'm going to pick up my globe.

So, are you ready? I'd like you to pause the video, and have a go with that now.

Okay, I've got my globe back.

Hopefully you've answered that question.

Now I'd like you to pick up your coloured pencil or pen, and we are going to mark your answers.

So you're going to tick or fix.

Hopefully we're going to do lots of ticking.

So the first one, we've already known that the Pacific Ocean is the largest ocean, so you can give that one a tick.

I already gave that one to you, but you can still tick it.

Then we have got the, Atlantic Ocean.

Is that what you wrote down? If you did, give yourself a tick.

If you didn't, don't worry, we're going to fix it at the end.

Then we have got the third largest ocean, which is the Indian Ocean.

Then the, Southern Ocean, and lastly the, Arctic Ocean.

Now, if there are some that you didn't get right, or your spelling is a little bit different from mine, it's important that you check it and fix it.

Even if you got it right, but you spelt it wrong, I'd still like you to use your coloured pen to write the correct spelling.

That's what really, really, really good geographers do, they make sure they spell things correctly.

Okay, you are working so hard, well done.

So now we are going to look at something called waves.

Have you ever seen waves in water before? You have, well, did you know that the ocean is constantly moving? The wind causes the ocean water to move in waves.

Steady and powerful waves can cause big waves and gentle breezes can cause small ripples.

Now, large swells in ocean water usually come from stormy weather, that means when we have a storm, we have lots of waves, big waves.

I'd like you to listen to the sound of these waves for a moment.

So I'd like you to close your eyes and I'm going to play some wave sounds, I'd like you to listen carefully, ready, listening.

How peaceful is it listening to some waves? Now, we have something called the polar regions, which are the coldest parts on our planet.

And the polar regions are at the top of our planet and at the bottom.

We've got the Arctic and we've got Antarctica at the bottom, called the North and South Pole, you may have heard of them before.

Now, the Southern Ocean surrounds Antarctica, it goes all the way around and touches, I will show you on my map, it goes all the way around here like this.

The Arctic is in fact, the coldest ocean on our Earth.

Even though we know that Antarctica is really cold, the coldest continent, the Arctic has in fact, the coldest water surrounding it.

Winds and other forces cause the water to be in motion, and it moves this water around the Earth.

This is called currents, when larger amounts of water move around the Earth.

Ocean currents can be warm or cold, so the water moving around the Earth can be warm or cold.

So you can see here, a picture of the Arctic waters.

And there's lots of chunks of ice in the water, isn't there? I wouldn't want to go swimming in there, would you? It'd be very cold.

So, we are going to read these statements and we are going to say whether they are true or false.

You can choose if you want to write these down, or you can point or say the correct answer.

So if you think it's true, you're going to say true.

Or if you think it's false, you're going to say, false.

Are you ready? So the first one is, waves are a form of movement in the ocean, waves are a form of movement in the ocean.

Is that true or is that false? It's true, waves are showing us that the ocean is moving, it's a form of movement.

Now B, the Southern Ocean surrounds Antarctica.

Is that true or is that false? It's true, well done.

C, the smallest ocean is the Pacific Ocean.

Is that true or is that false? It's false, it's not right.

The Pacific Ocean is the largest ocean, whereas the Arctic is the smallest one.

D, the Indian Ocean is near Africa, Asia and Australia.

Now that's a tricky one, because you need to have a really good knowledge of maps to know of our countries and continents to know if that's true.

But this one is in fact, true, and I can show you on our globe.

So here on our globe, need to hold it up straight.

We have got over here Asia, Australia and then across, we have got Africa the continent.

So this whole part here, is the Indian Ocean.

So that one is true.

And the last one, the Arctic Ocean is the warmest ocean.

Is that true or is that false? It's false, it's not the warmest ocean, it's the? Coldest ocean, you're right.

Now, I'd like to show you something, before we end our lesson.

Creating waves is what I would like us to do to end our lesson.

You are going to need a bowl.

Quite a large bowl, a flat one would be best.

And I would like you to put some water in there, and we are going to blow like this.

We are going to blow the water and pretend that we are the wind, and that way, we can create our own waves.

Let's have a look at how I want you to do it.

Okay, so what I've done, is I got my bowl, and I have got a wide bowl so that there's lots of area that I can see in the water, into my bowl.

What I'm going to do, is I'm just going to lean over like this.

I'm going to take a deep breath and blow,.

Did you see the waves in the water? I'm going to do it again, ready? Deep breath That's how you can make some waves, pretending that your breath is the wind.

What if I do it one more time? Now, your turn, can you have a go making some waves in a bowl of water? Okay, now that we've made our waves, it's time for, our end of lesson quiz.

The quiz is the part of the lesson, where you can test your knowledge to see how much you have learned this lesson.

Now, if you would like to send in your work to us, you can ask your parent or carer to send a picture on Twitter using the tag OakNational and the #ONAYear1 or #LearnWithOak.

And we'll be able to see it on there.

You've worked so, so hard today, and I'm really proud of you.
