Lesson video

Hi, everybody.

It's Miss Simkin here for your next science lesson.

I hope that you're having a good day.

And I hope that you are excited to learn all about the organisms, that means the animals and the plants, that live in desert habitats today because that is our lesson question.

What lives in a desert habitat? In today's lesson, we are going to start with our star words.

Then we're going to look at what a desert habitat is like, then we're going to learn about the desert organisms. Then we're going to do a matching activity.

And then at the end of the lesson, you have a chance to see how much you have remembered in the end of lesson quiz.

For this lesson, you will need a piece of paper, a pencil, a coloured pencil but you might want all of your colouring pencils today because we'll be doing some drawing and you're going to need your brain.

If you don't have any of those things, you can pause the video now and go and get them please.

Great, then that's just wake our brains up and then we'll be ready to begin.

So a gentle tap.

Hello, and then a shake to get the blood flowing and three deep breaths to get the oxygen.

Ready? Good job.

Let's say our star words.

I'm going to say them and then you're going to say them.

Desert cold, dry, hot, camel, cactus, scorpion.

Good job.

So a desert is the type of habitat we're going to be learning about today.

Cold is when something's a low temperature.

Can you do an action for cold? Good job dry mean something that's not very wet and hot is the opposite of cold.

It's when something's a high temperature.

Can you do the action for hot? Well, maybe because you're sweating.

Show me your action.

Great.

A camel, the cactus and a scorpion are the organisms we're going to be learning about today.

Remember an organism is anything that's alive, so it could be a plant or an animal.

Let's start with some recap.

Can you remember what a habitat is? A habitat is the natural join the action of an organism.

What goes in that gap? Can you say it for me? Great.

A habitat It's a natural home of an organism.

Good job.

And last lesson we looked at micro habitats.

Can you remember why I'm saying it in that voice? A microhabitat is a? Mmmh, habitat.

What goes in that gap? Say it to your screen.

Great.

A microhabitat is a small habitat that is? Mmmh, to the surrounding environment.

Can you remember what goes in that gap? Is microhabitat the same or different to its surrounding environment? Say it to your screen.

Great.

It's different.

So a microhabitat is a small habitat, that's different to the surrounding environment.

Good job.

Today we're going to learn about desert habitats.

So this is a picture of a desert.

And in the day deserts are very very hot, hotter than the hottest summer day here in the United Kingdom.

But this is something that might surprise you in the nighttime desert are very very very cold.

And deserts are very dry.

It doesn't rain in a desert, where it rains very very little.

So does it feel hot? When are they hot? During the day.

When are they cold? Good.

And then dry.

This is a map of the world.

And you can see the red parts show you where the deserts are.

So there's a big patch of desert environments here in Northern Africa and parts of the middle East.

There's a big patch of desert environments in the middle of Australia.

And then you've got some smaller places where you can find deserts to some small patches in North America and South America and down towards the South of Africa as well.

And then a little bit here on this Island next to Africa, which is called Madagascar.

You might have seen a movie about Madagascar.

Because that's where the deserts are in the world.

Can you get your finger and can you point to the desert that's in Australia.

Great.

That's down here.

What about the deserts that are in Northern Africa? Great.

There's the ones here.

Good job.

Okay.

What I would like you to do next please, is to write a sentence on your piece of paper with your pencil on how you would describe a desert.

A desert.

Deserts are? You write three things that desert are.

Giving you a clue.

Pause the video and write your sentence about deserts please.

Great, Good job.

Let's Mark your work.

Did you write something like this? Desert are hot during the day they're cold during the night, and they're very dry.

The main words you need to get in there are hot, cold, and dry.

So if you've written those words, you can give yourself a tick each time.

And if you miss one of them out, that's okay.

You can add it in now with your different coloured pencil.

If you need some time to mark your work, then pause the video and do that now, please.

Great.

Now let's learn about some of the organisms that live in a desert in a desert.

I keep saying that word wrong today, which is silly.

Coz it's the word main word in our lesson.

Maybe I need to practise it.

Desert, desert, desert.

Good job.

Do you want to practise too? Well done.

So the first desert organism we're going to learn about is the camel, maybe one of the most well known animals that lives in a desert.

Now a camel is really suited to a desert habitat.

It would have a much better chance of surviving than I would or you would if we turned up in a desert.

Because we don't have the same things that our camel has, that helps us to survive in a desert.

Now a camel can go a whole week without water.

Which is a really long time.

How long can it go without water? Say it to your screen.

A whole week exactly.

Camels also have really long eyelashes that's to keep the sand out of their eyes and their nostrils.

So the holes in their nose, they can actually close them.

They've got a flat that shuts close on their nostrils to keep the sand out as well, which is really clever.

Whereas we can't do that.

So we get lots of sand up our nose in a desert sand storm.

Now lots of people think that camels can hold water or store water in their humps.

That's actually not true, but they can store fat in that humps.

And this fat is like an energy store.

It's a food store.

So it means that they can go a long time without food as well.

Can you point to the camel and start tell me one thing that it has that helps it survive in the desert.

Good job.

Did you choose nostrils? I chose the nostrils one of my head, the next organism we're going to look at is the cactus, the spiky spiky, cactus.

So cactuses are also really well suited to live in the hot dry desert.

They've got spiky spines on them.

Can you say spiky spine and show me your spiky spine.

And those spines protect them from being eaten by other organisms. So even if a camel comes across a cactus, it's not going to be very tempted to bite into it because it's going to get a mouth full of spiky spines.

They also can store water inside their flesh.

So if you were to break into a cactus you'd see that it was very like juicy like full of water.

And they've got really long roots to help them find water that's far away underground.

Okay.

So they've got spiky spines.

Show me the action.

Good.

They've got long roots.

Show me your action.

And they store water.

So maybe we can do something like this.

Coz they're storing the water.

They're storing it inside them.

We might be able to think about action.

Maybe this water your choice, whatever is going to help you remember it.

Okay.

So let's practise one more time.

Show me your action for spiky spines.

Good job.

Show me your action for long roots.

Good job.

And show me the action that you've chosen for Storing water.

Good job.

Well done.

Okay.

And then our last desert an organism that we're going to learn about today is the scorpion.

Scorpions are actually part of the same family as spiders.

They're part of the arachnid, arachnid family.

I'm going to say.

And then you're going to say arachnid.

Good.

How many legs do spiders have? Can you show me on your fingers? That's fine.

Spider has eight legs.

And so just as scorpion let's count them.

So don't count this big pincers at the front, but let's count its legs because arachnids all have eight legs.

So let's check.

One, two, Three, four, five.

You can see it's hiding behind it's opisthosoma six, seven, eight.

So it does have eight legs.

So great.

Yeah, it's part of the arachnid family.

Scorpions are also nocturnal.

That means that they're mostly active at night time, which is good if you live in a desert, because remember it's really, really hot in the day.

So it's better to be active at night when it's much cooler.

Scorpions can also go a whole year without food.

I can't even go a day without food.

It's very impressive.

And scorpions are pretty fearsome little creatures because if they're threatened, they can curl their tail up.

And they've got a very poisonous stinger on the end of it.

Show me your poisonous stinger.

Exactly.

So you wouldn't want to get stung by a scorpion.

Okay.

So those are three desert organisms. What we're going to do now is I'm going to ask you please to draw a picture of each of our organisms and label it.

So we've got camel, cactus and scorpion.

Can you make sure that underneath your picture, you leave about two or three lines, a space where you can write some facts.

Okay.

So draw three pictures and leave a space under each picture.

Pause the video and do that for me now, please.

Great.

You haven't already, you can add some colour to your pictures or you can add some colour at the end of the lesson.

What we're going to do now is I am going to show you some facts about each organism.

There are facts that we've already learned that you've already heard, but I want to see if you can remember which fact matches which organism.

Okay? So are you ready for your first one? Here is your first fact.

Has a poisonous stinger.

Which organism is this about? Is it the camel, the cactus or the scorpion? Say it to your screen.

Good job.

It's the scorpion.

So now can you write this fact underneath your picture of the scorpion.

Be careful with the spelling of the word poisonous is on the screen.

So look carefully.

Pause the video and write this fact for me now.

Good job.

Okay.

Are you ready for the next fact? Has spines to stop other animals from eating it? Which organism is this about? Say it to your screen.

That's right.

It's the cactus.

Can you please write this fact underneath your picture of the cactus.

Pause the video and do that for me now.

Great.

Lets look at our next fact.

Has nostrils to keep the sand out.

Sorry.

Has nostrils that closed to keep the sand out.

That's the important bit, that they can close.

Which animal is this about? Say it to your screen.

That's right.

It's the camel.

Good job.

Can you write this fact underneath your picture of the camel.

Pause the video and do that for me now, please.

Okay.

We've only got two facts left.

You're doing great.

Good job.

Can go a year without food.

Which animal was this? Or I should say which organism.

That's right.

It's the scorpion.

Good job.

Can you write this fact underneath your scorpion.

Pause the videos do that now.

Great okay.

And here's our last fact of the day.

Can go a week without water.

Which organism was this? Tell your screen.

It was the camel.

Good job.

Can you write this fact underneath your camel please.

Pause the video and do that for me now.

Great.

Well done.

You have worked really hard today.

Good job.

I hope that you've learned lots about deserts and the animals and plants that live in them.

You can test your memory in the end of lesson quiz.

Thank you for all of your hard work today.

In our next lesson we're going to be learning all about rainforests and two of my favourite animals.

I can't wait.

So hopefully I will see you back here for another science lesson soon.

Bye everybody.
