Lesson video

In progress...


Hi everyone, I'm Miss Harris and welcome to today's science lesson.

Today, we are going to be comparing mammals and birds which are types of vertebrates.

Now remember a vertebrae is an animal which has a backbone so it has a spine.

So we are types of mammals.

So we are going to be comparing the differences and the similarities today.

Now, before we get started, at the end of the lesson I'm going to be asking you to tell me one living thing which lives in this habitat.

This is the desert.

It's a really hot place and not many animals survive here because there's a lack of water because it's so hot but there are some really special living things which can survive here.

Maybe you've thought of an animal already so keep it in your head till the end of the lesson.

So we are going to be recapping what vertebrates are, looking at what mammals are, what are birds, comparing birds and mammals, and lastly we've got our end of lesson quiz.

To complete today's lesson you will need an exercise book or a piece of paper, a pencil, a coloured pencil, and most importantly you will need your brain.

If you need to get any of these things, you can pause the video and go and get them now.

Well done.

So let's practise our star words.

So I'm going to say it then I want you to say it.

My turn then your turn.

Ready? Warm-blooded.








Good job.

Okay, my favourite part.

I'm going to describe an animal and I would like you to find it, are you ready? So get looking.

This animal is really long.

It can slither along the ground.

It's a type of reptile which has dry scaly skin.

This animal has a really long tongue.

This animal has got a really large mouth and it doesn't have any arms or legs and it makes this sound,.

What animal is Miss Harris describing? Can you point to it? Are you ready? It's a snake.

Did you get that right? Well done.

So let's recap what vertebrates are? So, so far we've learned about invertebrates which are animals without backbones.

So crustaceans, arachnids, and insects.

Today we're learning about vertebrates.

We're looking specifically at birds and mammals.

Pause point.

What is a vertebrate? Vertebrates have a what? What do they have? Pause the video and tell me the answer.

Vertebrates have a backbone.

Well done.

So all vertebrates have a backbone.

Great job.

So let's learn about some mammals.

I would like you to follow with your finger.

Are you ready? So mammals are some of the largest animals on earth.

So here's a picture of an elephant which is one of the biggest land mammals that we have.

They are warm-blooded animals and often have hair or fur.

So we can see here we've got a lion which is really furry, it's got a huge mane around its head.

And we've got a zebra which has got lovely stripey fur and it's got hair on its neck, a bit like a horse.

Mammals have pairs of lungs that help them to breathe.

All mammals, even the larger ones, live in water breathe oxygen.

So dolphins and things like whales and, not sharks, whales, can breathe oxygen so they don't breathe under the water.

Did you know that whales have got lungs as well because they are mammals even though they live in the water? Whales can hold their breath for up to two hours.

Our lungs are like two big bags and they're protected by some bones called the rib cage, they're like this and they go all the way round our chest.

Shall we fill up our lungs with air? So put your hands just under your armpits.

Ready? Take a deep breath.

Can you feel your chest filling up with air? Hold it, and breathe out.

Almost like we're filling up a bag of air when we breathe in and when we breathe out, the air gets pushed out of our lungs, help us breathe.

Now I would like you to draw some pictures to remember some facts about mammals.

So mammals have either hair or fur.

They are warm-blooded animals.

And they have a pair of lungs to help them breathe.

Can you draw some pictures to remember those three facts? Pause the video and have a go.

Well done.

So here are some pictures of some mammals.

We've got a giraffe, a killer whale, some pigs, and a rabbit.

So these are some mammals you might not have known were mammals.

In your books I would like you to draw three mammals so pause the video and do that now.

Well done.

So mammals give birth to live young.

Mammals look after their young for quite some time and protect it and care for it just before it's strong enough to protect itself and live potentially on its own.

So elephants care for their young for up to 10 years, that's a long time, isn't it? Kangaroos hold their young, so their baby, in their pouch for up to one year.

Whereas mice, they only look after their young for one month, so not a very long time.

Lots of mammals all have young and they look after it for different amounts of time like we've just seen there.

I would like you to now pause the video and answer this question, "What are these baby mammals called?" So here are some pictures of some baby animals.

They are mammals, what are they called? Let's check.

So we've got a puppy, a kitten, and a lamb.

So they are some young, that's what they're called, mammals, baby mammals.

Now let's learn about birds.

So birds are also warm-blooded animals just like mammals.

They have wings to help them to fly.

They have a really strong beak to help them to feed.

They all also have feathers.

Okay, so they have wings, a strong beak, and they have feathers.

Some birds have got webbed feet to help them swim, but not all birds, because some birds have claws to help them grip on to branches.

So we can see here, I've got some duck feet down the bottom here, and some eagle feet which have got sharp claws on them.

Now we are going to finish these sentences.

In your books I would like you to write all of these sentences, I keep pointing to the wrong place, can you write all of these sentences down into your book and fill in the gaps? So the first one says, "Birds have beaks to help them to mm." Number two, "Some birds have claws to help them mm onto branches." "Some birds have wings to help them to," and the last one, "Some birds have webbed feet to help them to mm." Pause the video and fill in the gaps.

Well done.

Let's check whether we've got the right answer.

So now pick up your coloured pen or pencil, we are going to tick or fix.

Ready? "Birds have beaks to help them to feed." So to eat.

"Some birds have claws to help them to grip onto branches.

Some birds have wings to help them to fly and some birds have webbed feet to help them to swim." Well done.

Now, not all birds can fly.

Some birds cannot fly and these are some examples.

Ostriches, penguins, and emus cannot fly.

They are birds which cannot fly.

Compared to these birds which can fly, so we've got a flamingo, a crow, a toucan, a robin, a canary, and a blue tit, these are all birds which can fly.

So let's recap.

Ostrich, penguin, emu cannot fly.

Flamingo, crow, toucan, robin, canary, blue tit can fly.

In your books, I would like you to write a list of birds which can and cannot fly.

So your sentences are going to up here.

"Birds which cannot fly are mm." So write a list.

"Birds which cannot fly are mm." So birds which can, birds which cannot.

And here are our list and I've jumbled them up to make it a bit more tricky.

So pause the video and do that now.

Well done.

So flamingos can fly.

A toucan can fly.

An emu cannot fly.

A robin can fly.

Penguins cannot fly.

Canary bird can fly.

A parrot, it can fly.

An ostrich cannot fly.

A pigeon can fly and an eagle can fly as well.

Well done.

Now let's compare some mammals and birds.

So here, I have got a table and we are going to read the facts and identify whether they are mammals or whether they are birds and we're going to put a tick whether it's a mammal or whether it's a bird.

So I would like you to draw this table.

So you're going to have either, actually no, we're not going to draw it, not going to draw, we're going to say it instead.

Is that better? Yeah, let's say it.

So the first one.

"This animal lays eggs." Does a mammal lay eggs or does a bird lay eggs? "These animals have feathers." Is it a mammal or does a bird have feathers? "This type of animal family is warm-blooded." Is that a mammal or is that a bird? "These animals give birth to live young." Is that a mammal or is that a bird? Now I want you to pause the video and I would like you to tell me which one is mammal or birds.

So read the facts, does it apply to a mammal or a bird or both, ready? Let's check now.

So, "This animal family lays eggs." Birds lay eggs, mammals do not lay eggs.

Well done.

"This animal family has feathers." We know that birds have feathers.

Well done.

"This type of animal family is warm-blooded." Both of these families are warm blooded.

Well done.

And lastly, mammals give birth to live young.

Great job.

Now, we have learned all about different animal families.

We've learned about invertebrates and vertebrates, and we've learned about all these animal families here and we've ticked them off.

Next lesson we're going to be learning about what each living thing might eat.

So we're going to look at some specific diets that some animals might follow.

Well done.

Now it's time to complete your end of lesson quiz where you can show off all of that wonderful knowledge that you have learned today.

Before we go, can you tell me an animal which might live in the desert? Do you know one? Can you tell me? Wow, great job, yeah, I think that animal might live in the desert but I was thinking of a scorpion which might live in the desert and also camels spend a lot of time in the desert too.

Well done.

You've worked super hard today as usual and we've got one lesson left in this animal kingdom unit.

I hope you've had a really good lesson and I will see you next time, bye.
