Lesson video

Hi everyone.

Oh let's make myself a bit bigger.

There we go.

` I'm Ms. Harris and welcome to today's geography lesson.

We are going to be looking at how we can protect our oceans.

Now during this lesson, I'm going to be telling you a story about a whale.

Now, our oceans are under threat because of lots of things that we as humans are doing.

Oh my color's out there.

I'm going to read you the story about a curious whale, who wants to cook a stew for his friend.

But the ingredient that he uses might not be what you expect.

And we're going to learn about what we can do to protect this really important environment.

So let's look.

We are going to recap the five oceans.

Recap what habitat is, we're going to listen to the story and we're going to look up plastic being in the ocean, and then we're going to do our quiz.

So we are geographers! Remember? So a geographer is a type of scientist who studies the earth, the land, and the people.

You will need a sheet of paper or an exercise book, a pencil and a coloured pencil, and your brain.

Let's practise some words that we're going to be using in this lesson.

My turn then your turn.

Habitat Threat.

Rubbish.

Plastic.

Reuse.

Impact.

Endangered.

Great.

So we've got our five oceans.

We have got the Pacific Ocean then at the top, in the middle, that way.

We've got the Atlantic ocean.

Then the Arctic ocean up at the top, Indian ocean and the Southern oceans.

There are five oceans.

Now habitat is where animals and plants live.

I would like you to fill in the gap and tell me what a habitat is.

Pause the video.

Have a go at that now.

Well done.

So a habitat is where animals and plants live.

We've got four habitats we've learnt about.

We've got the coral reef, the open ocean, the oyster reef and the Kelp forest.

They are the four habitats that we learned about last lesson.

Now this is Walter.

Can say "Hello Walter." I'm going to be telling you a story about this whale, who's called Walter.

He wants to make a special birthday surprise for his friend, and we're going to follow his journey to find the ingredients that he will need for his stew.

So let's take a listen.

Let's have a listen to the story.

And I'll like you to watch very carefully because I'm going to act out the story of Walter and his stew.

So one bright and sunny day, a whale named Walter was swimming around the ocean.

Walter is a very talented chef who loves to make delicious meals for his friends.

it's his friend Polly's eight birthday, and Walter wants to make her something extra special.

"What shall I make?" He thought to himself, "A cake? No, she wouldn't expect that.

Some brownies? No, that's really boring.

What about a stew? I will make a stew for her.

It will be made of all kinds of mouth watering ingredients.

She will love that." Walter began his journey, swimming through the clear blue sea.

Pumping his tail fin to propel him through the water along the seabed.

Walter searched in the depths of the ocean, looking around and around and suddenly out of the corner of his eye, he spotted his first ingredient.

He slowed stalking his prey.

This fish is known for his infamous ability to inflate when escaping.

Do you know what it could be? "The somewhat clumsy swimming style will help me catch it, but I must be careful of the spikes on its skin." Walter whispered to himself.

With a quick up and down motion of his fin and mouth open wide, he accelerated through the water.

"Hmm, the bitter taste and spongy texture will boil down perfectly into this stew adding a tantalising savoriness to my stew," he thought.

Puffer fish, ooh puffer fish.

An ingredient I shall choose into my pot.

It goes to two puffer fish in my pot.

What should I add next? I know Polly loves tiny fish.

I will look for those next.

With the flap of his tail, Walter was off again.

He was quickly immersed in the coral reef.

An incredible network of homes for a variety of beautiful fish.

His eyes boggled again.

He caught a glimpse of the second ingredient, resting in an anemone.

Do you know what it could be? It's bright orange and has a black and white stripe down the side of its body.

It's like a clown's face paint.

Clown fish, ooh clown fish.

They will add a sweetness to my mixture.

Another ingredient that I shall choose into my pot it goes.

"The stew is really coming along nicely," he thought to himself.

Walter continued swimming.

He weaved through the towering seaweed and sea grasses glistening in the sunlight.

"What components should I add to my dish next? I'm getting quite tired," he panted.

"I only need two more ingredients, Ah!" He shouted, interrupting himself.

The next ingredient to my stew, the sleek flattened body is hard to see.

Its body camouflage on the ocean floor.

All Walter could see was his eyes peeking out of the sun.

Do you know what it could be? This ingredient to his stew would be perfect, if he chopped it up into smaller pieces.

Then, resting in the sand, he captured it! Stingray, oh stingray.

Such a classic ingredients into my pot it goes.

In the distance Walter was swimming up to a bare part of the ocean bed.

No corals, no anemones, no rocks.

Just miles of sand.

"Where will I find any fish here?" He thought.

"It was worthless searching in this area." Walter slowed his fin and he moved his fin up and down, turning round until he caught the eye of his next ingredient.

A flurry of tiny red crabs, began to sprint as fast as they could away for him.

"Crabs! That's what I need." Walter hurried up to them, closing in, metre by metre, opening his mouth ready to catch them.

Crabs! Oh crabs.

The crunchy texture with fresh meat inside.

Into my pot, they go.

Lots of crabs.

Walter carried on swimming through the ocean in search of more fish.

Ahead of him he caught shimmer that was floating near the surface.

This fish has no brain, no heart, no bones or eyes.

It's hard to see in the water because it's clear and you can see straight through it.

Do you know what it could be? Walter needed to be careful around this marine predator.

It can sting it's prey using its tentacle arms. The sun was shining through the water, making it invisible.

Jellyfish, oh jellyfish.

How could I have forgotten? Another ingredient that I choose.

Into the pot it goes.

Walter had collected all his ingredients to make Polly's stew.

He had clown fish, puffer fish, stingrays, jellyfish and crabs.

All ready to be stirred into his favourite broth.

"But I need to add some last minute touches," he thought.

He needs to add some pepper and some salt.

"My masterpiece, it's complete!" Yelled Walter.

"Polly is going to love it." Did you enjoy listening to that story? Me too.

Now, were there some things, in Walter's stew, that we can't eat? You're right.

There were lots of things that Walter mistook, was mistaken for.

He thought that they were animals.

But they were in fact plastic.

Lots of our rubbish that's ended up in the ocean.

So here we've got the puffer fish and Walter mistook the puffer fish for plastic bottles.

Because when they're crushed, they look quite spiky, similar to a puffer fish.

We then had the clown fish, which he mistook for some straws, some plastic straws.

We then got a stingray, which Walter mistook for some black bags.

The we have some crabs which were mistaken for some lids of some plastic bottles.

And some jellyfish which he thought were plastic bags.

All of these plastics have ended up in the ocean.

Now, when you have a drink like a plastic bottle, or you have a sandwich from a shop, or maybe you buy a bag of apples.

Where do you think that plastic goes? Where do you put it? In the bin, you're right.

Now some plastics, like plastic bags, some of them cannot be recycled.

That means they can't be made into something else.

If it cannot be recycled and go in a special bin called a recycling bin, sometimes it can end up in the ocean and you can see from this picture here.

There's lots of rubbish all over this beach where it's been washed up from the sea.

So we need to think really carefully to make sure that we are not buying lots of plastic that might end up in the ocean.

Because sometimes this can happen.

Here we've got a plastic cup that's got a crab stuck inside it.

That can't be nice for the little crab.

We know that crabs don't live in plastic cups in the ocean.

And then we've got a turtle which is stuck inside some fishing wire.

Plastic can cause many problems for our animals in our ocean.

And plastic lasts for hundreds and hundreds of years before it disappears.

It degrades.

But what we can do, is we can recycle and we can make sure that we tidy up our beaches and that we buy things which are not made out of plastic so that we can use them over and over again.

Instead of using them once and then putting them in the bin.

We can use things that's are reusable.

That means we can use them again.

Can you write this sentence, To reduce our waste we can use.

So we can use what? What types of things? Reuse them.

Well done.

Can you write down this sentence, To reduce our plastic waste we can use.

Okay so instead of buying things that's made out of plastic, we can buy things which are reusable.

So here we've got some coffee cups.

You may have seen them before.

Now often when people are done with these, they just put them in the bin.

And sometimes they can't be recycled.

So instead we combine some reusable coffee cups like these ones to make sure that we use them again and again.

So a coffee cup looks this.

So this is my reusable coffee cup.

I can fill it up and I can use this again and wash it again.

So I can put my coffee in here and it keeps it warm, or my hot drink.

And that way I don't need to put it in the bin.

I can use it over and over again.

Now here we've got some plastic bottles.

What do you think we can use instead of buying a plastic bottle? So we can buy a reusable bottle.

This is my reusable bottle.

It's got a straw in it and I can use it again and again and again.

And I don't need to buy a plastic bottle because when I go to the shop, instead of buying a plastic bottle, I can ask them to fill up my water bottle from the tap.

Now here, we've got some plastic bags.

Instead of going to the supermarket and buying plastic bags, what could we use? We could use reusable bags.

I've got one here.

You can use reusable bags, which we can use again and again and again.

Good job.

Now what we've got here? We've got lots of fruit which is wrapped in plastic.

And often when you buy more than one, they come in plastic bags.

Now what's quite silly is that I take lots of these fruits which are in plastic bags, can actually not be in a plastic bag.

So where's my fruit bowl.

So I've got my fruit bowl here.

Can you see it? It's got lots of things in it.

I've got lots of oranges that I got from the Farmer's Market.

And I didn't need to have them in a bag because they were open like this.

Then I've got some apples which don't need to be in a plastic bag.

Some lemons, and I've got some bananas as well which are in my kitchen.

So they don't need a plastic bag.

So I combine them without the plastic bags because sometimes in some shops, they give you the option or you can go to a special place like a Farmer's Market to find fruits and vegetables which are not in plastic bags.

So maybe next time you go to the supermarket with your grown-up and you want to buy some fruit or some vegetables, can you find ones that are not wrapped in plastic bags? Great.

And that takes us to the end of our lesson.

We've had a lesson full of discussions today and lots of thinking about what we can do next time.

I would like you now, if you'd like to share your work with us, you can ask your parent or carer to take a picture and they can send it to us on Twitter, using the tag of @OakNational and the #LearnWithOak.

Now, because we are up to the end of our unit, I have made a super special end of lesson quiz.

Would you like to do the quiz? You would! Great! So you can have a go at doing our super special end of lesson quiz.

Have a great rest of your day and I'll see you next time.

Bye.
