Lesson video

This lesson is called Biodiversity.

We will be looking at what biodiversity means.

We will be exploring two different ecosystems and the damage that we are having on these places.

You will also complete the lesson by conducting a speaking and listening task.

In this lesson, you will need some paper or an exercise book, a pen or a pencil, your speaking mouths, and your eco-warrior brains.

Pause the video, collect your materials, and come right back.

Hello there, children.

My name is Mrs. Walsh, and I am an explorer.

In this lesson, we are going to learn about biodiversity.

Now, don't you worry if you don't know what that means yet, because you soon will.

You are coming on a journey with me around the world.

Shall we find out where we're going? Excellent.

Oh, here's a clue.

Can anybody tell me where the star is? South America.

Does anybody know what that flag is? Where is that a flag of? Who said Brazil? Brilliant, give yourself a pat on the back.

Today, children, we are going to Brazil, but let's find out why.

Oh, look at that cute animal.

How pretty.

Let's find out why we're here.

Brazil is the home of the Amazon rain forest.

15 to 20% of the world's biological diversity is in Brazil.

Around 700 species are discovered each year.

And the average temperatures of Brazil is 22 to 26 degrees.

Now, that is pretty warm.

Okay, children, before we start, I think it's really important that we understand what the word bio diversity means.

So let's break the word up.

Who's heard of any word with bio in it? Throw them at me.

Go on, throw them at me.

Biological, brilliant.

Biography.

Yep, that's a type of book, and that's a book about somebody's life.

So what do you think bio means? Brilliant, it means living.

So let's take the second part of the word, diversity.

Can you think about what diversity could mean? Yes, somebody said diverse, I could hear that.

So what does diverse mean? Oh, you are good children.

Diversity means a range of different things.

So pull the two together, biodiversity, and that means a range of different living things.

Well done.

Okay, let's take a look at this picture.

This is a picture of an ecosystem.

Can anybody guess what this picture is? Who said a woods? A woods, a forest.

Okay, let's go bigger and wetter.

Yes, a rain forest.

This is a rain forest, and a rain forest is an ecosystem.

Let's find out more.

All right, children, it's challenge time.

Pick up your pens.

You have 20 seconds to write down as many animals as you can think of that you think live in a rain forest.

Are you ready? Set, go.

Five, four, three, two, one.

Okay, pens down, children.

What did we get? Shout 'em out to me.

Shout 'em out to me.

A king cobra? You're correct.

Any more, a tiger.

Parrots.

Obviously, how can we forget the parrots? Hmm, no, not a shark.

Okay, let's see how you did.

There we go.

A king cobra, a tiger, some parrots, chimpanzee, rhinoceros.

And you get an extra point if you got vampire bat, because some people think vampire bats don't really exist, but they do.

They live in the Amazon rain forest.

All right, children, this is a nother ecosystem.

Can anybody guess what this one is? A fish tank? No, it's not a fish tank.

Think bigger.

Yes, it's a coral reef.

Challenge time again.

You have 20 seconds to think of as many animals that live in this coral reef.

Are you ready, set, go.

Five, four, three, two, one, pens down.

How did you get on? Should we take a look? Oh, fish, yes, absolutely.

Beautiful fish.

Colourful fish.

Any more? Yes, sharks live in the coral reef.

Not in the rain forest.

They live in the coral reef.

Any more? Seahorses, yes, they will do.

Yes, absolutely.

Let's take a look.

There we go.

Did you get any of these? Who said shark? You, you, you.

Yes, well, the one that I've got on here is a hammerhead shark.

So we do have beautiful, colourful fish.

We've got a hammerhead shark.

We've got sea turtles, they live in the coral reef.

Lobsters, sea horse.

Somebody said sea horse.

Now, this pink wiggly one at the bottom, does anybody know what that is? Yes, coral.

Now, did you know, children, that coral isn't a still pretty piece of rock, it's actually a living organism? Now, the sad thing is, children, this was once a rain forest.

And the second picture was once a beautiful, colourful coral reef.

Now, our human actions are ruining these beautiful places.

So carbon dioxide, which is a toxic gas, which goes up into the sky, pollution, which put your hand up if you're guilty of throwing your rubbish on the floor, oil, fishing, and the climate change, they are all responsible for ruining our beautiful rainforests and polluting our beautiful oceans.

I want you to think about what we can do to make sure that these places in our precious planet stay beautiful and healthy.

Pause the video and do that now please.

Welcome back.

These are my suggestions.

We can all pick up litter off the floor, wherever we are.

If we're walking along the street or we're playing out in the parks with our friends, and we see some litter on the floor, just pick it up and pop it in the bin.

We can plant a tree.

We can support charities.

So there are many, many charities out there that support the environment.

And if you want to, you can find out ways to support those charities.

We can reduce energy in our homes by turning down the heating, putting a jumper on if we're cold before we put the heating on, closing doors, and we can also encourage others around us.

So the people around us, we can influence those to stop doing some of these things and maybe encourage them to do better things for our environment.

Do you think you can do that, children? Excellent.

So now it's your turn.

It's time to get inventive.

What I would like you to do is I would like you to have a conversation with your parents and carers, or anybody that you live with, anybody who's your family and your extended family, I would like you to have a conversation with those people and come up with some ideas of how you can make a difference.

Now, you might decide that you are going to close all your doors when you are sat in the house.

You might decide that you're going to turn all the lights off when you're not using that one room.

You might decide to only put your heating on at a certain time.

But whatever you decide, I'd like to know your three top tips.

So remember children, you are having a conversation with your parents and carers.

And here is your success criteria.

Plan, plan what you're going to say.

Discuss, discuss how you can all make a difference to our planet.

And don't forget to write down your top three and remind your parents and carers what you have all agreed to.

Good luck.

I can't wait to see your conversations.

If you'd like to, please ask your parent or carer to share your work on Instagram, Facebook, or Twitter tagging @OakNational and #LearnwithOak.

See you soon.
