Hello there. It's very warm in the workshop today

so I'm making a fresh lemony drink to cool down.

Just need some ice cubes now to make it nice and cold.

The ice cubes are melting, I'd better get them in the glass.

Nice and quickly.

Boop-boop-boop.

Oh, this looks tasty!

ALARM BEEPS

Oh! I hear a beep, I see a flash, I wonder what they're going to ask?

-ALL: Hi, Nina.

-Hi.

-We've got a question for you.

-We live near Loch Ness.

Has Loch Ness always looked like this?

That's a great question - "Has Loch Ness always looked like this?"

Loch Ness is a really beautiful loch in Scotland.

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.

Neurons at the ready, Nina.

OK, today's question is - "Has Loch Ness always looked like this?"

Which Neuron do you think will be most useful

in helping us find the answer?

ALL: 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 hear.

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 or 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 Felix.

CHEERING

ALL: Go Felix! Go Felix! Go Felix!

Marvellous! A little touch can mean so much.

Today's question is - "Has Loch Ness always looked like this?"

Loch Ness is a big bit of water surrounded by rocks and mountains.

There's a lot to feel, so Felix, Touch Neuron, will be helping us

today. But stand by, Neurons -

I've a feeling I'll need help from all of you.

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

Kayla loves writing stories,

Max loves dressing as a superhero

and Cara loves eating hoc-chip cookies,

but they all want to know -

"Has Loch Ness always looked like this?"

I live near Loch Ness.

Loch Ness is really, really old.

Has Loch Ness always looked like this?

So, for one day only, Kayla, Max and Cara become the Explorers!

-Hi, guys!

-ALL: Hi, Nina!

Welcome to my workshop and thank you for your great question -

"Has Loch Ness always looked like this?"

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

Whoop-woo, a senses experiment! We're ready, Nina!

First, let's have a look at this model of Loch Ness.

And tell me what can you see.

-That's the loch.

-Yeah. Loch Ness is a long, narrow

and very deep loch and there are lots of famous stories

about a big friendly monster living here called Nessie.

Loch Ness looks beautiful now, but a very, very long time ago

you wouldn't be able to see Loch Ness at all

because it was completely covered in ice.

Let me show you...

Brr! Brr! With all that ice it must have been very cold?

-It was very cold, Felix.

-What happened with all that ice, Nina?

Good question, Luke. Some blocks of ice were as big as mountains

-and these were called glaciers.

-Glaciers!

Oh-ho-ho, that's a cool word!

There are no glaciers in Loch Ness any more.

But there are still some in other parts of the world,

let's have a look...

It looks like that glacier's moving.

Yes, glaciers do move, but only very slowly.

Oh, ho-ho-ho!

Egh! Egh! That feels all squidgy!

-Oh, no, please put it down, Nina?

-Oh-ho-ho-ho, sorry, Felix,

I just want to demonstrate something with the slime.

OK, guys, you've got some slime in front of you there.

Why don't you pick it up?

ALL: Ew!

-What does it feel like?

-It's gooey!

-Yeah?

Slime is pretty squidgy,

but it actually moves the same way a glacier does.

A glacier forms on high mountains and they slide downhill slowly...

a bit like this slime.

Ha-ha! Let's do an experiment!

This drainpipe will be a pretend mountainside.

You can see there's some rocks there

and our slime is our glacier.

Let's make this a proper mountainside by lifting it up.

Heh!

It's like a glacier.

Nina's glacier looks like a slow-moving river.

-What do you notice about the rocks?

-They've been moved by the slime.

That's right. As our glacier moves, it pushes the rocks along with it.

They've got stuck in the slime.

The same thing happens with real glaciers.

So icy glaciers get rocks stuck in them too?

That's right, Belle. Loch Ness used to be covered in a huge icy glacier

and as the glacier moved along, it pushed some rocks out of the way,

-but others got stuck in the glacier.

-What else did the glaciers do, Nina?

Well, glaciers did lots of interesting things.

To find out more, I think we need to go somewhere wild and mysterious.

Off we go for another adventure.

Nina said it's somewhere wild and mysterious!

-Maybe it's a huge sandy desert?

-Desert - hot sand and prickly cacti?

-I do hope not.

-We've arrived.

This is the famous and mysterious Loch Ness.

-So what can we see from here?

-We can see the loch and the mountains.

We call this a valley or a glen, and it's just like

our slime experiment in the workshop. Many years ago,

a huge icy glacier moved down through here

and pushed all the rocks in the middle out of the way.

How do we know that a glacier was here, Nina?

Great question, Belle. Let's experiment...

-What can you feel on this rock?

-Big scratches.

-Yeah, and what do you think made these big scratches?

-The glacier.

You're right. The huge glacier that was here

made these big scratches in this rock. Let's see how it did it.

We are going to pretend that these pieces of ice are glaciers

and that these pieces of clay are rocks, so let's see what happens

when we rub the ice over the clay. So, everyone,

take your piece of ice... and rub it over the top!

Woo...

Now, has the ice made any scratches in the clay?

No, it just looks the same, Nina.

Do you remember how our slime from earlier

collected rocks on its way down the mountain?

-Yes, Nina.

-Well, let's pretend our ice has collected some rocks.

So this time we're going to use these ice cubes,

which have some sand stuck to them.

-What happened this time?

-There are scratches on the clay, Nina.

Yes. Because the sandy ice cubes have a rough surface,

when we rub them over the clay they made scratches.

And a huge glacier made the same thing happen here in Loch Ness

many, many years ago.

Ah, the glacier slid down and got rocks stuck in it.

-And the rocks made big scratches.

-That's right, Neurons.

What happened when the glacier melted, Nina?

That's a brilliant question! Come with me to find out.

-What can you see over there?

-A hill.

-Yes, well, it looks like

a hill, but it's actually a big pile of rocks that were left here

when the glacier melted. But how did this happen?

Let's experiment.

Have a look at this, guys. This block of ice

has sand and stones frozen inside it. It's our pretend glacier.

And we need it to melt. But this would take ages to melt,

cos it's quite big, and real glaciers take years to melt.

So I left another pretend glacier to melt yesterday. Look...

And...here it is.

Wow! Nina's glacier has disappeared!

The ice on our glacier has melted

and turned back into runny water again.

And what's been left behind?

-Sand and stones.

-Yes, the sand and stones that were stuck in the ice

have been dropped here. And this is exactly what happened

many, many years ago to lots of the glaciers.

The icy weather stopped and the weather got warmer,

which made the glaciers melt.

So the rocks the glaciers had picked up were left behind?

That's right! When the glaciers melted,

they left big piles of rocks, like that one over there.

Ice changed the world around us,

and we can still see where glaciers have been today.

# Nina and the neurons. #

So, your question was - "Has Loch Ness always looked like this?"

And I think we've answered it.

We found out that Loch Ness

used to be covered in a huge, icy glacier.

Glaciers slide down mountainsides and rocks get stuck in them!

Moving glaciers make BIG valleys.

And leave big scratches so we can see where they've been.

But when a glacier melts,

the rocks that it picked up get left behind. Marvellous!

So I hope that's answered your question.

ALL: Thanks, Nina! Bye!

You're welcome! Bye!
