Lesson video

Hi, everyone.

I'm Miss Harris.

Welcome to today's geography lesson.

We are going to be learning all about what lives in the ocean.

You may already know some marine creatures, but we're going to learn about some more today.

So let's take a closer look at what we're doing.

We are going to be recapping the five oceans.

We're going to look at some types of habitats.

We're going to look at the types of marine life and discussing where they live in the ocean.

And then we're going to do some drawing of some animals that live in the ocean.

Are you ready? Are you sure? Are you super sure? Super-duper sure? Great.

Let's recap what a geographer is.

A geographer is a type of scientist who study the earth, the land, and the people.

So that's what we are going to be today.

You will need a sheet of paper or an exercise book.

You will need a pencil, a coloured pencil, and most importantly, your brain, well done.

Let's practise some of the key words we're going to be saying and using in this lesson.

The first one: habitat.

Did you say it to your screen like I did? Let's do it again.

Habitat.

Good.

Mollusc.

Crustacean.

Fish.

Coral.

Mammals.

Mammals.

Fish.

Coral.

Habitat.

Mollusc.

Oh, you're so fast.

Well done.

Okay, are you ready? I'm going to say an ocean and I'd like you to find it on the map.

So get your finger ready.

Is it ready? Ready? Get the pointing finger ready.

Go to make it bigger.

Can you find the Pacific Ocean? Ready, three, two, one.

There it is, it's on two places on our map because remember, our map is flat, whereas our earth is round.

So on our, let me get my globe.

Let me get my globe.

Remember that the Pacific Ocean is this huge part here.

Can you see it? So remember, when we have our map, it's almost like we chop it and then open it up, so it's flat.

So it comes up twice on our map, but actually it's just one huge ocean.

Ready? Next one, can you find the Atlantic Ocean, please? Point to it.

Ready? Atlantic in three, two, one.

There it is, it surrounds.

So the surrounding continents are North America, Europe, Africa, and South America.

Then at the top, we've got the Arctic Ocean.

So we so far we've got Pacific Ocean, Atlantic, the Arctic, can you find the Indian Ocean next? Find it on the map and point to it.

Ready? There it is.

The Indian Ocean is near Africa, Asia, and Australia, the three continents which start with a.

Then another continent that starts with a, can you find the Southern Ocean? It surrounds a continent that begins with a, can you find it? The Southern Ocean surrounds Antarctica.

Great job.

Okay, now, a habitat is where what lives? Animals and plants, fantastic.

Can you fill in the gaps on my definition here? A mm is where mm and plants mm.

Can you pause the video and write down what is a habitat? Off you go.

Great job.

So a habitat is where animals and plants live.

Let's look at some habitats.

I'm going to tell you about four habitats.

The first one is a coral reef.

Can you say that? Coral reef.

Good.

Now, some habitats are shallow, sunny, and warm, whereas others are deep, dark, and cold.

And different plants and different animals live in different areas.

We've got the open ocean, the oyster reef, and we've got the kelp forest.

So let's take a look at the coral reef.

So the coral reef is formed over thousands of years.

And each coral reef is made up of little colonies of tiny animals called polyps.

Coral reefs love the warm waters in the tropics.

And corals are in fact tiny little animals.

Did you know that? So some of them look a bit like rocks, don't they? Different coloured rocks.

But they're in fact little animals.

And 25% of all marine animals live in the coral reef.

It provides a really safe home and protection for lots of tiny little animals and fish and things like that.

Then we've got the open ocean, which is an area of the ocean that isn't near any land.

You will find some of the biggest marine animals here, like the whale that you can see in this picture.

The whale, a sperm whale, needs lots of space so that it can swim around and come up to the surface to breathe.

We've then got an oyster reef, which is similar to a coral reef because they provide a home for plants and animals, and oysters are little animals too.

Maybe someone in your family eats a lot of seafood and they might eat oysters because that's part of some seafood that people like to eat.

Then we've got a kelp forest.

A kelp forest is like a huge underwater rainforest and over a thousand species of animals, so different types of animals and plants live amongst the kelp.

Now I would like you to draw these four habitats and label what their name is.

Pause the video, have a go at that now.

Well done.

Now, there are lots of different types of animals that live in the ocean.

And we're going to learn about the different animal families.

The first one is an animal family called mammals.

What are they called? So mammals are types of animals which have warm blood and have lungs.

Do we have lungs to help us breathe? You're right, we do.

Put your hands down the side of your body and take a deep breath and breathe out.

Do one more.

Breathe out.

Inside our body, we got a rib cage, which is like a big cage of bones like this.

And it protects all of our organs in our body and it protects our lungs, they're like big bags.

And when we breathe in, they fill up.

And when we breathe out, they get smaller.

Mammals, we are types of mammals, and mammals in the ocean have lungs too.

So if we are mammals and there are mammals that live in the ocean, do you think they can breathe under water? Think, can we breathe under water? No, we can't breathe under water.

And even animals that live in the ocean and the seas that are mammals, they can't breathe under water.

They come up to the surface to breathe and then they dive back down again and they can hold their breath under water for a really long time.

These animals are like this one, a sperm whale, a dolphin, and killer whales.

They come up to the surface to breathe and then they dive back down.

So considering how big these animals are, where do you think they live? Do they live in the coral reef? Do they live in the oyster reef? Do they live in the open ocean? Yeah, you're right, they live in the open ocean because they need lots of space to swim around near the surface so that they can come up to breathe and then go back down again.

And you can see the tail here of a whale and it's diving back down.

I would like you now to fill in the gaps to tell me what a mammal is.

So a mm is an animal with mm blood and mm.

So once you've written that sentence and filled in the gaps, choose an animal, and I would like you to draw one of these mammals.

So you're going to write what a mammal is and then draw a picture of a mammal.

Pause the video, have a go at that now.

Well done.

Which animal did you draw? Which mammal? Wow, lovely.

Let's check what a mammal is.

A mammal is an animal with warm blood and lungs.

Did you write that down? Great.

Now the next type of animal are fish.

Fish have something called gills, which help them breathe under water.

Do we have gills? Do mammals have gills? No, because we can't breathe under the water.

Gills are organs which help animals breathe under water.

Which animals? Fish, well done.

So we've got tuna, a sea horse, swordfish, clown fish, and salmon.

There are hundreds and hundreds of other types of fish, but these are ones that I thought were quite interesting.

I like the swordfish 'cause the nose is like a sword.

Where do you think they live? Where do you think fish live? So most fish live in the coral reef.

And you can see a picture here of lots of fish in the coral reef.

Now, same thing, I would like you to tell me what gills are and then draw a picture of a fish.

So fill in the gaps and then draw one picture of a fish.

Pause the video, have a go at that now.

Excellent.

Let's check what gills are.

So gills are organs which help animals breathe underwater.

Which fish did you draw? Wow, that's a good one.

Okay, the next animal family are called crustaceans.

Can you say that, crustacean? Well done.

A crustacean is a cold-blooded animal which has a hard skeleton on the outside of its body.

So our skeleton is inside our body.

We've got skin and muscle and lots of other things and fat surrounding our bones, but a crustacean has its skeleton on the outside to protect it.

So let's look at some crustaceans.

We've got a lobster, a shrimp, a starfish, and a crab.

Can you put your hands like a crab? Where do you think they live? So crustaceans can live anywhere, really, in the ocean.

They have been found in the coral reef, in the oyster reef, in the open ocean and in the kelp forest.

They live pretty much anywhere, really.

Now, can you write about a crustacean? Fill in the gaps and then draw a picture of a crustacean.

Pause the video, have a go at that now.

Well done.

So a crustacean is a cold-blooded animal which has a hard skeleton on the outside of its body.

Which crustacean did you draw? Wow, great.

So remember that they can live anywhere, really, in the open ocean.

In the open ocean? They can live anywhere in the ocean and that could be in the open ocean, it could be in a coral reef, an oyster reef or a kelp forest.

Now the last animal family we are going to look at are molluscs.

Can you say that word? Mollusc.

Good.

A mollusc is a cold-blooded animal and most have gills just like fish to help them breathe under water.

And some molluscs live inside a shell.

So they're cold-blooded, they have gills and some live in a shell.

Let's have a look at some types of molluscs.

We've got an octopus.

Now, does an octopus have a shell? Does this picture of the octopus have a shell? No, it's really squishy.

And molluscs, some of them are really, really squishy when they don't have a shell.

Like jellyfish, it's in the name, it's like jelly.

Then we've got mussels.

Now, mussels have got the squishy part inside the shell.

They live inside the shell to protect them.

Then we've oysters as well.

And this one's a silly one, it's called a blobfish.

Have you ever seen a blobfish before? That's what a blobfish looks like.

Looks like a bit of a silly face, like a blob.

Now, molluscs can live, again, they can be anywhere, really, in the ocean, but most of them are found in coral reefs, oyster reefs and kelp forests.

Can you fill in the gaps to tell me what a mollusc is and then draw a picture of one mollusc.

Pause the video, have a go at that now.

Well done.

Let's check what a mollusc is.

A mollusc is a cold-blooded animal with gills and some live inside a shell.

So here we can see a picture of a coral reef.

It's really colourful and there are lots of little animals that live in the coral reef.

You've worked so hard today and learnt a lot about different animal families that live in the ocean.

Which was your favourite? Me too.

Great job.

Now, if you would like to share your work with us, you can ask your parent or carer to take a picture of your work and they can upload it to Twitter using the tag OakNational and the hashtag LearnWithOak.

If you would like to do your end of lesson quiz to show off all your knowledge, that would be really great.

If not, I will see you next time.

Have a great rest of your day.

Bye.
