Lesson video

Hello everybody, welcome to your science lesson with me, Miss Roberts.

I'm so excited to be teaching you all about ecosystems because I love ecosystems. I find them fascinating hearing about animals and organisms, what they do and where they live.

I've got a friend with me and if you've not met him before, this is Lenny the Lion.

And he always sits by my screen and listens to all of my learning because I do a lot of talking to my screen and I know that you're going to have to as well, because it helps us to keep things sticky in our minds.

If we're saying things out loud, as well as writing things down.

So he's going to sit by my screen.

If you want to go and get your favourite Teddy by your screen, then you can pause the video and go and get them now.

Okay.

So let's have a think about what we need for this lesson.

You will need a pencil or pen, a ruler and a notebook.

So things to write with, pause the video and go and get the resources you need now.

Okay.

In this lesson, we're going to do the following.

First of all, we're going to learn about our star words.

And I'll talk you through those.

If you've not done star words with me before.

Then we're going to learn about habitats and do some recapping on knowledge you already have.

Then we'll learn about ecosystems. And then at the end, I have a task for you.

Okay, are we ready to get started? I said, "Are we ready to get started?" Fantastic.

Okay.

So if you've not done star words with me before they go like this, my turn and then your turn.

Star word, star word, star words, Oh, you can do it louder than that.

So I'm going to flash my hands like stars, and I'm going to say star words.

And I want you to do the same.

So my turn, then your turn, star words, star words, star words.

Well done.

Okay, I think we're ready for our first star word.

The first word is habitat.

You're turn habitat.

Your turn.

A habitat is where an organism lives.

A habitat is where an organism lives.

Well done.

The next star word is micro organisms. I'm going to make it bigger so you can read it.

Micro organism.

Your turn.

micro organism.

Your turn.

Well done.

Now you'll notice on the screen that I've underlined half of the word organism I've underlined the prefix micro.

In the word habitat.

I said that it's where organism lives.

Can you remember from your previous learning what is an organism? Can you tell your screen? Well done, an organism is a living thing.

An organism is a living thing.

What's an organism, a living thing.

Well done.

So if I spot a living thing, then I've also spotted on organism.

Well done.

Now the prefix micro, on microorganism on the screen, hmm.

What does micro, if something's micro, here's your clue? What do you think it means? Really, really, really, really, really, really small.

Micro or microscopic is something that's really, really small.

You can only see under the microscope.

A micro organism is a living thing that you can't see.

A microorganism is a, your turn, living thing that you can't see, well done.

So of action for star words.

Microorganism is micro organism.

Okay.

Let's do that again, micro organism.

It's a living thing that we can't see.

What's a microorganism, team? Well done.

And our last star word is ecosystem? Your turn.

Ecosystem.

Your turn.

So does anybody know what an ecosystem is? If you do, can you write it down now? If you need more time, pause the video 'cause I'm going to tell you what's an ecosystem is.

An ecosystem is a collection of animals, plants, habitats, and micro organisms. Okay, so an ecosystem is a bit like a town or city.

So it's made up of lots of different parts, but the difference is that it's just the living things and their homes.

So the action for the star words ecosystem is ecosystem.

And the reason that I'm doing my hands like this is because it's made up of all the different parts.

So it reminds me that it's made up of the plants, animals, habitats, and microorganisms. So let's do that star word again, now with the actions and then we'll get the definition and then we'll carry on.

So my turn, your turn.

Ecosystem, your turn.

Ecosystem, your turn.

An ecosystem is a collection of animals, plants, habitats, and microorganisms. What's an ecosystem, team? It's a collection of, with me, animals, plants, habitats, and micro organisms. Well done.

So team, if I have a collection of animals, plants, habitats, and micro organisms, what have I got? Tell your screen.

Well done? I've got an ecosystem.

Fantastic.

And that's what our whole unit is based on.

all about the different parts of an ecosystem.

So one of the parts of an ecosystem is habitats.

So to think about habitats, first of all, we need to think about what animals need to live.

You're an animal.

What do you need to live? Can you tell me the things that you need? Well done.

Let's see if you've got them all.

You need food and water.

You need air in order to breathe, you need space to reproduce and you also need space to grow.

So all of these things are what animals need to live.

They also need to do this in a place that's safe to do these things.

Then this needs to be somewhere they can breathe and grow.

They need to be able to find enough food and water to stay alive.

And when they produce young or babies, that's needs to be in a place that they will survive.

For example, if I moved habitats from the earth into the sea, I would not be able to survive because I wouldn't have enough air because I can't breathe underwater.

I wouldn't be able to get food because I wouldn't be able to get the fish.

So it would be really difficult.

In fact, impossible for me to live in a habitat under water.

So this lesson, we're going to be touching on more about habitats and different places where animals and organisms live.

A habitat is a home where organisms live.

Can you read that definition to the screen? Habitat is a home where organisms live, well done.

So can you tell the screen, what habitat does a fish have? Where does a fish live? Well done.

Some of you might have said the sea and some of you might have said a pond.

Both are correct.

What about a lion? Where does a lion live? Well done.

And that is its habitat.

Where do birds live? What about a Blackbird in the UK? Mostly it lives in the trees because that's where it can get all of the things that it needs.

So I'm going to show you a different habitat.

This is the rainforest.

Now on the screen, you'll see that it says macro habitat.

Now we've already seen the word micro organism.

And that meant a really, really, really small organism.

Macro is the opposite.

So what do you think it means? Can you tell your screen, what do you think macro means? Well done.

Macro means large.

So this is a large habitat.

So macro habitat means a large habitat.

So the rainforest is a really big place.

Can you tell your screen what animals can you see that live in the rainforest? Well done.

You might have said elephant.

You might have said giraffe or monkey or parrot or raccoon or hippo.

There's lots of different animals that you can see on the screen.

You might've also said snake slithering in the tree canopy there.

Now those are the animals that live in the rainforest, but they're not the only type of organism, plants are also an organism.

So you can see lots of different plants on your screen, can't you? Can you point to three different types of plants that you can see? I can see one there.

I can see a red one.

I can see a tall tree, and I can also see some lily pads.

That was four.

Which ones can you spot? Point to the video about the plants that you can see now.

Well done.

So all of the animals that you've named and all of the plants live in the rainforest.

So we would say that heir habitat is the rainforest.

Where is their habitat, team? It's the rain forest.

Well done.

As an example, an elephant would not be able to survive under water so it could not live in the habitat of the sea because it wouldn't be able to breathe under water and it wouldn't be able to eat.

And it wouldn't be able to produce its young.

So it would die.

That's why it lives in the rainforest because it can get everything it needs to survive.

Okay, here is another macro habitat.

This is the Arctic.

This is the Arctic, well done.

Which two organisms can you see on the screen? Well done, you can see a mummy polar bear and baby polar bears.

So polar bears live in the Arctic.

Polar bears live in the Arctic.

So can you tell me what's the habitat of a polar bear? the Arctic well done.

This is another macro habitat and this is the woods.

What animals do you find in the woods? Can you tell your screen? What's else? Good job.

You might find birds in the trees.

You might find insects in the ground.

You might even find, I wonder if you picked up a log, what would you see underneath the log? Well done a wood louse or even some worms. All of those creatures have the habitat of the woods.

That's where they live.

So it's their habitat.

So team, can you tell your screen, what's the habitat of a bird? Well done the woods.

Now we've looked at macro habitats, which are the big habitats.

We can also have micro habitats and we've looked at the prefix macro and micro.

What does micro mean? It means a very, very, very, very small, well done.

So on the screen, you can see a micro habitat.

This is a very small place where an organism lives.

Where are those ants living at the moment? Can you tell your screen? Well done.

They're living under a leaf.

So the micro habitat here is under a leaf.

What about in this picture? What are those organisms that you can see? Well done, they're worms. Where are they living? They're living in the soil.

So what's the worms microhabitat? It's in the soil, well done, team.

I'm going to give you an awesome cheer, because you've been working so hard.

There's been lots and lots of talking so far today.

So really well done.

Now let's have a look at ecosystems. I'm going to give you a definition of an ecosystem, because remember so far, we've looked at the fact that it's the different parts.

An ecosystem is a community of animals, plants, and microorganisms together.

Team, I'd like you to pause the video and read out the definition of what an ecosystem is to your screen now.

Well done.

Let's read it one more time together.

And we're going to do the actions like the star words an ecosystem is a community of animals, plants, and microorganisms together.

So if ecosystems are all of the different parts, let's go and look again at our rainforest picture.

The ecosystem here is made up of the rainforest, which is the habitat.

The rainforest is the habitat, then the water, the animals, the fish, and then the algae.

Now algae is something that would be living in the water.

And it's very, very, very, very small.

So we can't even see it.

That reminds me of one of my star words.

What was our star word for an organism that's so small you can't even see it? Well done, I could hear you! It's a micro organism.

Algae is a micro organism.

Algae is a micro organism.

Well done.

So all of these parts together make up the ecosystem.

In this picture, I'm showing you a different ecosystem.

First of all, I want you to tell me what animals can you see? Can you tell your screen? Well done.

I wonder if you got ducks.

I wonder if you saw the deer.

I wonder if you saw the frog and the fish and the dragonfly? I've named five there.

Did you get any of those now? Now I want you to tell me what plants, you can see, pause the video and name all of the plants that you can see in this picture.

Well done.

Did you get daisies or lily pads or trees or reeds around the edge of the pond? You've done really well.

Now, I want you just have a go at naming all of the other things that you can see that you've not already named.

So things that aren't a plant or some of the animals that you've named already pause the video and have a go listing all of the other things that you've not already said.

Well done.

I wonder if that was a bit hard.

So you could have had the water or the soil or the trees.

Those are all parts of the ecosystem and also the rocks.

There's something else that you can't see.

What was that microorganism we just learned about in the previous slide? Do you remember? It was called al.

Algae, well done.

And the algae is so small that you can't see it, but it's in the water.

And that is a micro organism, which is also part of the ecosystem.

So now what I'd like you to do is note down all of the animals, the habitats, the plants, and the microorganisms that we talked about in that picture.

Well done.

Okay, pause the video if you need more time.

We're going to do another example.

Hey, is a different ecosystem.

Oh wow, this is under water in the sea.

And this is a coral reef.

First of all, I want you to tell me what animals you can see.

What can you see in this picture? Well done.

You can see lots of fish.

What habitats can you see? Hmm, interesting.

So I can see the macro habitat of the sea.

I could also maybe live under one of the coral or within one of the plants that I can see.

What else can you see? Well done.

You can see lots and lots of water and what can't you see? Well done.

You can't see the micro organisms in the water or in the coral.

I want you to jot these down now, team.

Which animals could we see? Which habitats could we see? Which plants could we see and what microorganisms? I'm just going to go back one step for a moment.

Because to clarify, coral is a living thing, even though it might just look like it's there forever.

So have a go now at listing all of the things that we talked about.

Well done.

Pause the video if you need more time.

And here is a list of the things that you might've written down.

This isn't every single one, but these were the main ones that I thought about the animals were the fish and the coral, the habitats were under the coral or in the sea.

The plants were seaweed, or even you might've seen some sea grass.

The microorganisms were algae that we've talked about and also some bacteria, which is so, so, so, so so small that you can't see it with your bare eyes.

You need to put it under a microscope so that you could see bacteria.

Well done.

If you want to pause the video and add some of the ones on that, you missed then please do that now.

Okay.

I now have a task for you.

I would like you to join up the definition with the correct title.

So on the left hand side, you've got organism, habitat, microorganism and ecosystem.

And on the right hand side, you've got your definitions, the natural home of an organism, a community of plants, animals, microorganisms, together with their habitat, anything that is alive and an organism that's too small to be seen by the human eye.

I'd like you to pause the video and join up the definitions.

Now using a ruler, or you could download the worksheet and do it on that.

Well done.

Pause the video if you need more time, 'cause I'm going to go through the answers.

Okay.

An organism is anything that is alive.

A habitat is the natural home of an organism.

A microorganism is an organism that's too small to be seen by the human eye.

And an ecosystem is a community of plants, animals, and micro organisms together with their habitats.

Wow, well done, everyone.

I've been so impressed with your learning today.

I'm really proud of you, for your first lesson on ecosystems. Well done everyone.

Lenny the Lion here, I'm really excited to teach you the rest of this unit.

So make sure you join us for lesson two on ecosystems next time.

Bye everybody.
