Wooo!

Hello, I'm playing with my new toy.

It's very clever(!)

It can be small like this.

Or big like this!

Ha-ha-ha!

Woo, whoop!

But it always stays the same round shape.

Hee-hee.

DOOT DOOT

I see a flash, I wonder what they're going to ask.

-Hi, Nina.

-Hi.

We've got a question for you.

How do we know the Earth is round?

That's a great question. How do we know the Earth is round?

Why don't you come down to my workshop and we'll investigate?

ALL: See you soon, Nina! Bye!

Bye.

I'm going to need some help to answer this one

and I know just who to ask. OK, Neurons, time to get to work.

ALL: Neurons at the ready, Nina.

Today's question is how do we know the Earth is round?

Which Neuron do you think would be most useful

in helping us find the answer?

ALL: Me! Me! Me!

Will it be...Fabulous Felix?

I can help so very much if you need the sense of touch.

Will it be...Beautiful Belle?

I send messages to brain from ear,

if there's a sound I'll help you here.

Will it be...Lovely Luke?

For looking and seeing, day or night,

I'll help you with your sense of sight.

Will it be...Awesome Ollie?

If it's pongy or whiffy,

but you can't tell, my messages help your sense of smell.

Or will it be Baby Bud?

Sour, salty, bitter, or sweet, I'm your taste buddy whenever you eat.

-It's Luke.

-CHEERING

-ALL:

-Go, Luke.

Go, Luke!

Go, Luke!

Cool, Nina.

I'll be looking out to help you!

Today's question is how do we know the Earth is round?

Because we can see a round shape, Luke will be helping us today,

but stand by, Neurons, I may need help from all of you.

I need to get the workshop ready before the Explorers arrive.

Charlie loves his bike, Katie loves holidays

and Zak likes Taekwondo,

but they all want to know, how do we know the Earth is round?

There's a round model Earth at school.

But outside the ground looks flat.

How do we know the Earth is round?

So, today, for one day only,

Charlie, Katie and Zak become the Explorers.

Hi, guys.

ALL: Hi, Nina.

Welcome and thank you for your great question -

how do we know the Earth is round?

To find out the answer, let's start by using our senses.

ALL: Woot-woo, a senses experiment.

We're ready, Nina.

We live on a big planet called Earth,

which looks like this.

The blue parts are water.

Which are the seas and the oceans

and the greeny parts?

Well, they're land.

-Now, what shape is this?

-Round!

Yes, and the real Earth is round too!

Why does the ground look flat?

Well, let's play a ball game to find out.

Yippee! A ball game! My favourite!

Here is a really small ball,

so let's see what it looks like close up using the Nina Cam.

Oh.

Now, does it look curved or flat?

Curved.

The small ball is really curved, but planet Earth,

where we live, is much bigger than this, isn't it?

So I think we should try a bigger ball.

Woot-woo.

Ha-ha-ha!

Now let's see what this big ball looks like closer up.

Ooh.

Now, does it look more curved or more flat than a small ball?

More flat.

Yes, the bigger ball is less curved than the small ball,

so it looks flatter.

But Earth is much bigger than this ball too.

So, hold on a minute.

Whoa. Whoa.

Whoa, ho-ho. Ha-ha!

Come on.

Ho-ho, I think this is a bit bigger.

LUKE: Whoa, ho-ho, that is a huge ball!

Imagine playing football with that.

So, let's see what this really, REALLY big ball looks like up close.

Whoa.

Now, does it look more curved or flat?

-Flat.

-Yes.

As the balls got bigger and bigger, the top looked flatter and flatter

and that's what happens on the real Earth.

The real Earth is much, much bigger than this ball.

It's so big, the ground looks flat to us.

But, really, it's gently curving, like the top of a gigantic ball.

But how do we know the Earth is round, Nina?

We need to see the Earth from a bit higher up to find out.

LUKE: Here we go!

I can't wait to see where we'll end up today.

-OLLIE:

-Nina said we have to see the Earth

from somewhere a bit higher up.

Oh, maybe we're going on a rollercoaster!

That's really high up!

And really noisy.

Whee!

Well, we're about to find out, Neurons, we're here.

So, in order to help answer your question -

how do we know the Earth is round -

we need to see the Earth from somewhere a bit higher.

The sky.

Ah, yeah!

OK, so far we've found out that we live on a planet called Earth

that is round. But cos it's so big, the ground looks flat,

when actually it's a gentle curve.

So how can we see what shape the Earth is?

Well, maybe my little astronaut friend will be able to explain.

Ha-ha, say hello.

ALL: Hello, Mr Astronaut.

-OLLIE:

-Oh, Mr Astronaut, so cute.

Now, when we're standing on the Earth, like we are now,

we can't see the shape of it.

But if we were to go very, very high up into the sky -

way up above the clouds -

we would be able to see what shape the Earth is.

So we're going to do an experiment to see

what the Earth looks like from very, very high up.

FELIX: Ooh, I'm not sure going up that high is very wise, Nina.

No, we're not going high up, Felix,

something else is going to do that for us -

a giant balloon.

This is a very special balloon that can go really high.

We have permission to do this

and we've got experts helping us, so you can't do this at home.

Can you see underneath the balloon here,

there's a box with some tiny cameras in it

and these cameras are going to record

what shape the Earth is from way up high so that we can see it.

But I think this balloon needs a captain.

How about we send Mr Astronaut in his space rocket up there too?

ALL: Yeah!

Mr Astronaut will be able to see

what the Earth looks like from very high up.

Oh, I've always wanted to see the world.

Are we ready to launch?

ALL: Yeah!

Let's count down.

Five, four, three,

two, one, blast-off!

NEURONS: Bye, Mr Astronaut!

Hooray, our balloon and Mr Astronaut are on their way

and soon they'll be very, very high up in the sky.

I can't wait to see what the camera records,

so thank you so much for helping us.

Will the balloon ever come back down again?

We'll have to wait a while to find out.

You asked how do we know the Earth is round

and so far we've found out that we live on a planet called Earth,

which is round. It's so big that the ground looks flat,

but really it's a gentle curve.

And we also found out that if we were to go

very, very high up into the sky, we could see the shape of the Earth

and there are special balloons to do it for us.

So I wonder how our balloon got on.

Well, does anyone recognise this?

It's Mr Astronaut.

Yes! So the balloon did eventually come down, but a long way from here.

So Mr Astronaut's had a bit of an adventure, haven't you?

Let's have a look at what the camera recorded

and see what shape the Earth is.

That's when we launched the balloon.

Mr Astronaut's getting lifted very high up into the sky.

Oh, he's really, really, really high now.

LUKE: Whoa, look at the astronaut,

he's on top of the world.

So, this is what the camera recorded.

So what shape is the Earth?

Round.

Exactly, because our camera was so high up,

we can see that the Earth is round

and I've got another fun way to show that the Earth is round.

Let's play a game.

So, here is a big globe of the Earth

and we're going to do a bit of travelling.

We're starting here and we want to go...over there.

So, shall we take the plane?

Yeah, are we ready to take off?

Go.

And we're here. Well, that was a very short flight.

I'd like to see more of the world, let's take the train next.

Let's see some train choo-choo arms. Choo-choo!

ALL: Choo-choo!

Choo-choo!

Choo-choo, choo-choo!

I love train sounds.

Choo-choo, choo-choo.

Oh, we've gone halfway round the world.

But we've come to a bit of sea, we need to take the boat.

Need to paddle. That's it, let me see your paddling arms everyone.

All the way round, keep going.

Paddling in the boat and we've come to dry land,

let's drive the rest of the way. Seat belts on, everyone.

Steering wheels ready.

ALL: Brrrm!

Well, that was fast.

They're back already.

Hey, that was a brilliant trip. Well, where are we now?

Back where we started.

Yes, we've gone right round the world.

We went forward the whole time

and we've ended up back where we started.

Explorers did that many years ago

and that's how we found out the Earth is round.

# Nina and the Neurons! #

Your question was how do we know the Earth is round

and I think we've answered it.

OLLIE: We live on a big planet called the Earth that is round.

-LUKE:

-Because the Earth is so big, it looks flat.

-FELIX:

-But really it is a very gentle curve.

BELLE: Special cameras can go very, very high up in the sky,

and record what shape the Earth is.

-BUD:

-And we can see that it's round!

So, I hope that's answered your question.

ALL: Thanks, Nina, bye.

You're welcome, bye.

If you want to know more about the science all around us,

go to the Nina section on the CBeebies website. Have fun.
