Lesson video

Hi everyone.

I'm Miss Harris.

Welcome to our second lesson of our Animal Kingdom Unit.

Are you doing well today? Good.

Now we are going to be looking at the differences between invertebrates and vertebrates.

I'm going to be explaining to you what those words mean and what the differences between those are.

Now invertebrates and vertebrates are how we classify animals.

So we can put all animals into two groups either invertebrates or vertebrates.

Now at the end of the lesson, I'm going to be asking you to tell me what animal lives in this habitat.

So this is a coral reef.

At the end can you tell me one animal which you know lives in the coral reefs.

So keep it in your head if you've got one now.

Well done if you've got one now.

Let's find out what else we're learning today.

So we're going to be recapping what's a living thing is.

Learning about what is an invertebrate, what is a vertebrate and identifying some different animal families and lastly, our end of lesson quiz.

Before we get started, these are the things you will need, an exercise book or a piece of paper, a pencil, a coloured pen or pencil and your brain.

If you need to get these things, pause the video now.

Well done.

Let's practise our Star Words.

So I'm going to say it then I want you to say it, Are you ready? Living thing.

Vertebrate.

Skeleton.

Hard.

Spine.

Invertebrate.

So we've got invertebrate, vertebrate.

Get that fine, well done.

Now, in each lesson I'm going to be describing an animal and I would like you to find it so that we can get our brain nice and warmed up.

Are you ready? So the animal I'm thinking of, is white, it has got some paws, four paws, it walks on four legs, it has got round ears.

It lives in a very cold place called the Arctic.

It can swim in really cold water.

And it's furry.

What animal am I describing? I am describing a? Polar bear, did you get that one right? Well done.

That was a tricky one, wasn't it? There's lots of animals on here which are white.

Now let's recap what a living thing is.

So there are five features to a living thing.

The first is all living things need to be able to breathe.

Take your hands, put them on the side of your chest take a deep breath and breathe out.

Breathe in, hold it, now breathe out.

So all living things need to breathe.

All living things need to feed.

So they need to eat.

And they can choose whether they only eat meat or plants or both.

It's up to the animal.

It depends on what animal it is.

All living things reproduce so they can have babies.

And all living things produce waste.

So they go to the toilet.

Do elephants have toilets like this? No, they just go to the toilet anywhere in the wild.

So do lots of other animals.

And lastly, all animals grow and change over time.

So us as humans we don't stay babies forever.

We need to grow up so that we can protect ourselves like all animals in the animal kingdom.

Now I would like you to use your finger to connect the picture of the feature of a living thing to its label.

So pause the video, do that now.

Right, let's check whether you've got the right answer.

So first we've got waste, growing and changing, feeding, reproduce, and breathing.

Let's learn about what an invertebrate is.

So here's the definition and we're going to read it and I'd like you to follow your finger across the screen.

Are you ready? So an invertebrate, ready? Is an animal which does not have a backbone.

They either have a soft body like worms and jellyfish or they have a hard casing covering their body like spiders and crabs.

So your backbone, what I want you to do is, I want you to take your hand, put it round the back of your neck, just below your neck here, then lean forward to tip your head down towards your chest so your chin is on your chest.

And then I want you to move your hand up and down.

Can you feel all the bony bits on the back of your neck? Can you feel that? They are your, that's your backbone.

Those bony bits are your spine, parts of your spine.

Your backbone.

Invertebrates do not have one of those.

So they are either soft or they have a hard casing covering their body.

So that's recap.

Invertebrates do not have a backbone.

Can you do that? They do not have a backbone.

They are.

They either have any soft body like jellyfish and worms or they have a hard outer casing like a shell covering their body like spiders and crabs.

Now I'm going to show you what an invertebrate.

The description of an invertebrate but using a bowl of jelly.

So let's have a look.

So I've got bowl here of jelly.

Now the reason I'm using a bowl of jelly to show an invertebrate is because jelly is soft and squishy, like the inside of an invertebrate.

Now they do not have a backbone.

So they either have a soft body like worms and jellyfish or they have a hard outer casing of their body like spiders and crabs.

So, first I'm going to show you to tip my jelly upside down.

It's going to be the shape of my bowl.

So put that together.

So here I've got my jelly.

This is what a jellyfish might look like and a worm.

We know that a worm is a long shape, but the jellyfish body looks like this really squishy and we can poke it.

Now an invertebrate does not have a backbone.

So it's going to be nice and soft like this.

An invertebrate might look like this or it might have a hard outer casing so, I can touch the jelly like this, if it's a jellyfish or worm.

But if I put my bowl back over the top, can I get to the jelly now? Can I touch the jelly? I cannot touch the jelly because my bowl represents the hard outer casing of an invertebrate.

So then I put it back down.

Can I get to the jelly? No, but if I lifted it up I can.

So it's either like this a soft body, or it has a hard shell like this over the top.

So that is how jelly represents invertebrate.

So now hopefully we're a little clear about what an invertebrate is.

So let's write down some facts.

The first sentence says, an vertebrate is an animal which does not have a? So they either have a soft body like a jellyfish or worm, or this sentence here, or they have a hmm outer casing covering their body.

Can you pause the video? Write the sentences down and fill in the gaps.

Let's check, pick up your coloured pen or pencil.

We're going to tick or fix.

We're going to tick if we've got the right answer or fix it if we've got the wrong answer.

So they do not have a backbone and they either have a soft body or a hard outer casing.

Now here are the two pictures of some invertebrates.

Can you pause the video and tell me the name of these invertebrates.

And press play when you're done.

So we have got an ant and a snail.

Well done.

So I'm going to show you a table now which helps us identify invertebrates.

So some invertebrates, they either have legs or they don't have legs, so they either have legs or they don't have legs.

Okay, so jointed legs remember we looked at crabs, so a crab is a type of invertebrate and they have legs which bend like this, they've jointed legs.

So our fingers have got joints in them.

And that's what a crabs legs are like.

So now we can see a list of animals here, so we have got sorry, a list of how many they've got.

So they either have three pairs of legs, which we can see and let me make it bigger for you.

So all we can see now a list of animals which are all invertebrates.

Some have three pairs of legs, some have more than three pairs of legs.

And some are worm-like and some are not-worm like.

So let's see what animals we've got.

So we've got an ant, a cockroach, a ladybug, which have three or more pairs of legs.

We then got a.

So here we've got a scorpion.

Then we've got worm-like invertebrate like an earthworm or a leech.

And then lastly we have got not like a worm so it doesn't have legs but it's also not like a worm which is a tape.

So these are lots of invertebrates here.

In your books, I would like you to draw three invertebrates.

Pause the video and do that now.

Well done.

Now let's learn about what a vertebrate is.

So follow with your finger.

Sorry, we're learning about what a vertebrate is.

Vertebrates, vertebrates are animals which have a backbone inside their body.

So vertebrates do have a backbone.

So we are vertebrates because we have a backbone.

The major animal families include fish, amphibians, birds and mammals.

So they are some of the animal families, which are vertebrates.

So they have a backbone, they do have a backbone.

And here are some of the animal families.

So you might recognise some of these animals and they are vertebrates.

They have a backbone.

So now we've got our pause point.

Can you name these two types of vertebrates? So we've a goldfish and a pigeon hopefully you knew the names of those.

Now we're going to write some facts about a vertebrate.

So what a vertebrate? Vertebrate are animals which have a hmm inside their body.

What do they have inside their body? Pause the video and write that sentence down filling in the gaps.

Well done.

So they have a backbone inside their body.

So let's look at the table again.

So here we've got vertebrates, vertebrates.

They are warm-blooded or cold-blooded.

So we've got here other animal families.

We've got mammals, birds, fish, reptiles, and amphibians.

Here are some examples of those animals which are vertebrates.

So some, you can see that mammals and birds are warm-blooded, whereas fish and reptiles and amphibians are cold-blooded.

Can you draw three vertebrates in your book.

Pause the video, do that now.

Well done.

Now let's identify some animal families.

So there are lots of different types of animal families.

And in this unit of work, we will be learning about each group.

So there are two categories, we've got invertebrates and vertebrates, which we have learned about today.

There are then as you can see, different animal families in each group.

So vertebrates, we've got crustaceans, arachnids and insects.

Whereas invertebrates, we've got fish, amphibians, reptiles, mammals and birds.

Over the next few lessons, we are going to be learning about each group that is in these two categories.

Some are invertebrates and some are vertebrates.

Some are invertebrate, some are vertebrate.

Now it's time for your end of lesson quiz where you can show off everything that you have learned today.

You've worked super hard and I'm really impressed.

But before we go, can you tell me which animal lives in the coral reef? Well done.

So you could have said any fish which you know that lives in the sea in the coral reef but another animal you might not know are crabs, live in coral reefs and so do some types of sharks some smaller ones.

Well done today and I'll see you next time.

Bye.
