Lesson video

Hello, my name is Ms. Chorekdjian.

I'm so excited to be learning with you today.

I will be helping you with your geography lesson.

We are going to have a great time learning together today.

Let's get started.

Welcome to today's lesson from our unit called, "Continents and Oceans: what can we find out about the world?" This lesson is called, "The World's five Oceans." Your learning outcome will be to explain what an ocean is and name Earth's five oceans.

Some of this learning is brand new, but I'm here to help you.

This links back to previous learning you might have done using globes, satellite images and geographical vocabulary to describe Earth, and you might have located and named Earth's seven continents.

I'm really excited to get started, I hope you are too.

Here is a list of all of the keywords that we will be using together today and their definitions.

Before we find out what these keywords mean, let's practise saying them together.

Ocean, ocean.

Earth, Earth.

Life, life.

Tourist, tourist.

Good job everyone, well done.

Let's find out what these key words mean.

Ocean.

An ocean is a very big area of salt water between the continents.

Earth.

Earth is the name of the planet that we live on.

Life.

Life is the time between birth and death.

Tourist.

A tourist is someone who travels to a different place from where they live for a holiday.

I want you to be using these key words throughout our lesson as well.

Here are the learning cycles that we will be working through together in today's lesson.

First, we're going to be looking at Earth's five oceans.

We're going to be locating them and naming them, and then we're going to be thinking about the importance of oceans.

Are you ready to start your learning for today? Good job, fantastic, let's begin.

Planet Earth is round and covered with water, called oceans, and land.

This is a 2D map of the world.

That means it's a flat map of the world.

It's not a 3D globe.

Most of the surface of the Earth is made up of water, about three quarters.

So if you look at that map there, you can see that there are more areas that are ocean because those areas are coloured in blue.

The bits that are coloured in green are the land.

So remember the oceans cover about three quarters of the Earth's surface.

This is why it's called the, "Blue planet." It's called the blue planet because most of the Earth's surface is made up of water and water is coloured blue.

Let's have a check here.

Roughly how much of the Earth's surface is covered with water? A, one quarter? B, half? Or C, three quarters? Pause the video and complete that check.

How did you get on? Did you say C, three quarters? That's correct, well done, you can give yourselves a thumbs up.

Good job everyone.

Oceans are large, joined up areas of salt water covering Earth's surface.

Water on Earth can be separated into five oceans.

I wonder if you can look at this map and see where you might separate all that water into five different oceans.

Pause the video and see if you can have a guess.

How did you get on everyone? Did you think about where the five oceans could be? We'll be looking at their location a little bit later.

First, let's have a check here.

There are mm oceans on Earth.

A, seven.

B, six.

Or C, five.

How many oceans are there on Earth? Pause the video and complete this check.

How did you get on? Did you say C, five? That's correct, there are five oceans on Earth.

Remember I told you we'd be locating those oceans? Here they are.

Did you guess their location correctly? The five oceans on Earth are as follows, the Atlantic Ocean, the Pacific Ocean, the Arctic Ocean, the Indian Ocean and the Southern Ocean.

Did you separate those oceans correctly? Now, you might be thinking, "Why are there two Pacific oceans?" It's rather not two separate oceans but one large ocean.

Remember I told you that the Earth is shaped as a sphere, like this.

It's a ball, and it's really difficult to represent that ball as a flat 2D map.

So when we've got the Earth like this, in order to lay it down flat, there has to be a cut somewhere.

So we'll cut it down one part of the world and fold it out flat.

And the two parts here that you can see where there's a Pacific ocean on the right and a Pacific Ocean on the left would've been joined up on this side if there were a sphere like this.

So there are five oceans on Earth.

Let's go through saying them so that you remember.

Atlantic Ocean, Atlantic Ocean, Arctic Ocean, Arctic Ocean, Pacific Ocean, Pacific Ocean, Indian Ocean, Indian Ocean, Southern Ocean, Southern Ocean.

Good job everyone.

Hopefully you've remembered the names of those oceans.

If you want to have a go here looking at the names and locating them with your partner, you can pause the video here for extra practise.

Great, let's move on.

It's now time for a quick check.

Name the five oceans.

Pause the video and complete that check here.

Did you tell your partner the names of all the oceans? Did you say the Atlantic Ocean, the Pacific Ocean, the Arctic Ocean, the Indian Ocean and the Southern Ocean? Well done if you got those correct.

Here are some images of the five oceans.

Here's a picture of the Arctic ocean.

So the Arctic ocean you can see looks quite cold because there's lots of bits of ice floating in that ocean.

The Atlantic Ocean, the Indian ocean.

So there's a nice warm sunset over that Indian ocean.

Southern ocean, so again, you can see some icebergs in that ocean, so again, it looks quite cold.

The Pacific Ocean.

So this ocean looks really warm and sunny.

You can see the bright blue seas and the clear skies.

Pause the video and talk about these different oceans.

What do you think's the same about them? What do you think's different? Do you think that all of these oceans are the same temperature? Pause the video and discuss these oceans.

How did you get on? Did you say that maybe the Arctic ocean and the southern ocean are the coldest because you can see icebergs floating there and you know that ice is only when it's really cold? Did you say that the Indian ocean and the Pacific Ocean might be the warmest because you can see clear blue skies and you can see a little bit of colourful greenery in the Pacific Ocean picture? And then maybe the Atlantic ocean might not be icy and it might not be too warm.

It might just be average temperature.

Well done, I'm sure you managed to have lots of good discussions there about all of the Earth's five oceans.

Let's continue with our learning.

It's now time for a true or false question.

That means we've got to think really carefully about whether or not this statement is true or false.

It says, "Earth's oceans contain fresh water and salt water." Is that true or false? Pause the video now and answer that check.

How did you get on? Did you say false? That's correct.

Now, we've got to think about justifying our answer and thinking about why it's false.

Here are some answers that you could choose from.

A, oceans are large bodies of joined up salt water.

Or B, oceans are large bodies of fresh water mixed with salt water.

So which of those reasons justifies why that statement is false? Pause the video and complete that check.

How did you get on? Did you say A, oceans are large bodies of joined up salt water? That's correct, good job everyone, you can give yourselves another thumbs up.

This is fantastic learning for today.

It's now time for task A.

What I would like you to do is to locate and label Earth's five oceans on your map.

Pause the video and complete task A.

How did you get on? Did you locate and label Earth's five oceans? Here they are.

Here's the Atlantic Ocean.

Here's the Pacific Ocean.

Here's the Arctic Ocean.

Indian Ocean, and Southern Ocean.

And did you remember to locate the Pacific Ocean in two different areas? Because that's where we said if we had a sphere world it would be cut in half and laid out flat.

So both of these sides would be the Pacific Ocean.

Good job everyone, you can give yourselves a big thumbs up.

It's now time to move on to the next part of our lesson.

So now we're going to be thinking about the importance of oceans.

Oceans are really important to so many different people, plants and animals, and we're just going to be thinking in a little bit more detail as to why they're so important.

Oceans are important for all life on Earth.

Why do you think oceans are important? I want to see what you know first before I tell you.

Pause the video and do this as a think, pair and share activity.

Why do you think oceans are important for life on Earth? How did you get on? Did you say things that could be included in this list? Like oceans are important as a home for plants and animals.

Did you say that oceans are important to provide food for humans? They could also provide food for animals and plants as well.

And oceans are important because they're places for tourists to visit and to have fun.

I'm sure you said those answers and you could have said some other things as well.

Let's look in more detail now about the importance of oceans.

Oceans are important as a home for plants and animals.

It's thought that oceans are home to half or three quarters of all living things.

So if you can imagine all of the living things on Earth, all the plants and animals, about a half of them or three quarters of them live in the oceans.

That's a huge amount.

So it's now time to have a quick check.

What fraction of living things are thought to live in the oceans? A, one half to three quarters? B, one half to one quarter? Or C, one quarter to three quarters? Pause the video and complete that check.

Good job everyone, how did you get on? Did you say A, one half to three quarters? That's correct.

So one half to three quarters of all living things are thought to live in the oceans.

Good job everyone, you can give yourselves a big thumbs up.

That's fantastic.

Oceans support food and jobs for humans because of fishing for eating and selling.

So you can see there's a man there who's a fisherman and he's hauling in his net and he's going to collect that fish and either eat it and use it to feed his family or he's going to sell it to restaurants and shops so that they can use it to support their families and other people can go to the shop or the restaurant and eat the fish.

Oceans and beaches are also important for tourism.

Remember we said that tourists are people that visit different places to learn about them and to have fun.

Tourists spend money which supports local communities.

If a tourist comes to your community and buys something and gives you money in exchange for that, it then helps you to have that money so that you can then go and buy food or buy things to make your life more comfortable.

You can see some pictures here of how tourists spend time and money and enjoy the oceans.

Have a look at these pictures and discuss them with your partners.

What can you see the tourists using the beaches and oceans for? Pause the video now.

How did you get on? Did you say that tourists enjoy beaches and activities linked to oceans such as swimming, snorkelling, diving, scuba diving and boat tours.

And they might also go along the beach and walk and maybe collect some shells and they might also do a little bit of sunbathing too.

So those are all the different ways that tourists enjoy the oceans.

And remember that we said tourism supports local communities.

Well done everyone.

Let's have a quick check here.

Why do tourists visit oceans? Is it A, for hiking? B, to visit beaches? C, snorkelling? Or D, boat tours? And I'll give you a clue here.

There's more than one correct answer.

Pause the video and complete that check.

How did you get on? Did you say B, visiting the beaches, C, snorkelling, and D, boat tours? That's correct, those are the main reasons why tourists visit oceans.

Tourists mainly go hiking in areas where lots of hills are or lots of mountains.

Well done if you said beaches, snorkelling and boat tours.

Good job everyone, you can give yourselves a thumbs up, and that's fantastic learning.

Oceans also supports wellbeing, connectedness to nature and create a sense of awe and wonder at the plant and animal life and ocean landscapes.

Have a look at these two pictures here.

One is of that beautiful fish and coral reef and the other one is a nice picture of a beach and a bay.

Look at that ocean landscape.

Talk about with a partner why it's so important that we appreciate oceans linked to our wellbeing and our connectedness to nature.

How did you get on? Did you talk about appreciating all of the plants and animals that share the world with us? Did you talk about those beautiful ocean landscapes making you feel at awe and at one with nature? That can all help us really appreciate life on Earth and how special it is.

Well done everyone.

It's now time for a true or false check.

That means you've got to think carefully about whether or not this sentence is true or false.

"Oceans are beautiful to look at, but not important." Is that true or false? Pause the video and answer that question.

How did you get on everyone? Did you say false? That's correct.

Now let's think about justifying our answer and explaining why it's false.

Is it A, oceans are important for all life on Earth? Or B, oceans are important only for human life on Earth? Pause the video and answer that check.

How did you get on? Did you say A? That's correct, oceans are important for all life on Earth.

They are beautiful to look at, but we talked about other reasons why they're important.

Well done if you got that right, you can give yourselves another thumbs up.

We're doing some fantastic learning so far together in today's lesson.

It's now time for task B.

What I would like you to do is to draw and label a picture to show why oceans are important.

You could draw a picture of an ocean landscape, a way people use the ocean, or something that lives in the ocean.

Pause the video now and complete task B.

How did you get on completing task B? Here's my example.

I've said oceans are important as a home for plants and animals, food for humans and for tourism.

And then I've drawn a picture here of one of my favourite animals, which is a turtle, and I've labelled it to say, "Turtle." I've said that you can swim with turtles and that turtles live in the ocean and that the ocean is a home for the turtle.

Well done if you did something similar.

Good job everyone, you've worked really hard today naming and locating the world's five oceans and also thinking about why they're important.

We've now come to the end of our lesson.

Let's go through a quick summary of all of the learning that we've completed together today.

The ocean is a large joined up area of salt water covering nearly three quarters of Earth's surface.

We have five named ocean areas, the Pacific, Atlantic, Indian, Arctic, and Southern oceans.

And finally, oceans are very important for all life on Earth.

You've been fantastic today.

You can give yourselves one last thumbs up.

Well done for joining me today and for completing your learning with me.

I'll see you soon for more geography lessons.

Goodbye.
