NINA HUMS

Ho-ho! Oh, hello!

I'm just looking...

Oh no! I think my light bulb's blown.

Oh dear, it's definitely gone. I'll need to change the bulb.

The bulb will be too hot to touch now.

I'll wait for it to cool down.

-BEEPING

-Oh!

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

ALL: Hi, Nina!

Hi, guys!

-We've got a question.

-What is fire?

That's a great question. What is fire?

Fire is hot and has lots of flames,

but what is it made of, where does it come from?

Come down and we'll do some experiments to investigate.

ALL: See you soon, Nina.

-Bye!

-Bye!

I'll need some help to answer this one and I know who to ask.

OK, neurons, time to get to work.

ALL: Neurons at the ready, Nina.

OK, today's question is - what is fire?

Which neuron will be most useful in finding 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 hear.

Will it be lovely Luke?

For looking and seeing, day or night

I'll help with your sense of sight.

Will it be awesome Ollie?

If it's pongy 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 Felix!

-CHEERING

ALL: Go, Felix! Go, Felix! Go, Felix!

Go, Felix! Go, Felix! Go, Felix! Go, Felix!

Marvellous! A little touch can mean so much, Nina.

Today's question is - what is fire?

Fire is very hot and can burn us, we must never touch it,

so Felix will help me stay safe.

I need to get the lab ready for the experimenters.

Diarmuid likes his scooter,

Mia loves her globe and Ronan likes rally cars.

They all want to find out what fire is, so today, for one day only,

Diarmuid, Mia and Ronan become the experimenters!

ALL: Hi, Nina!

Welcome to my lab! Come in!

Ha-ha! Oh, it's lovely to see you all.

So your question is, what is fire? Why do you want to know?

We know it has flames and we know not to go near it.

-But we don't know what it's made of.

-Yes, fire has very hot flames,

that's why it's dangerous.

Fire can burn us,

-so it's important that everyone listens to me, OK?

-OK.

-Brilliant.

For our first experiment we'll use our senses.

ALL: Woo-hoo! A senses experiment! We're ready, Nina!

This is a Bunsen burner,

it's a special piece of scientific equipment used in labs

for doing experiments.

I'll light it carefully, so can you take a step back?

That's good.

I'll pop on a heat-proof glove...

So, what does the flame look like?

-It's red and orange.

-And it's flickering.

The flame can't stay still.

I wish fire wasn't so dangerous!

It makes me a little scared.

It's good to be a little scared of fire, Bud.

It's important to know when things are dangerous so we don't get hurt.

OK, guys, I'm going to turn the lights down

so we can see what the flame looks like in the dark.

-Can you still see the flame?

-ALL: Yes!

It looks really bright.

Yes, so as well as giving out heat,

fire gives out light as well.

Let me put the lights back up...

I'll turn this off...

So we've learnt that fire has colourful flames that always move,

and fire also gives out lots of heat and light.

But fire needs certain things to do this. We need another experiment!

We'll use candles for this experiment.

-Never touch candles at home, but you know that, don't you?

-Yes.

These two candles are burning.

What would happen if I put this jar over one of the flames?

-It would go out.

-It might get smaller.

It might get bigger.

We'll just have to see.

Careful, Nina! Don't touch the hot flame!

I won't, Felix.

I'll put my heat-proof gloves on to be extra safe.

OK...

Let's watch very closely to see what happens to the candle flame.

-The flame is still burning brightly.

-But keep watching.

Oh! The flame's gone out.

That's because it's trapped in the jar, so it's run out of air.

Although we can't see it, air is all around us.

We need air to live and so does fire

because there's something important in air - oxygen.

Oxygen is a gas in the air,

and our bodies need oxygen to breathe

and fire needs oxygen to burn.

Although we couldn't see it, the jar had air in it,

and the flame kept burning until all the oxygen was used up.

And this candle here, it's still burning,

because there's air all around it.

It has all the oxygen it needs, just like we do.

But if I starve it of oxygen...

(It'll go out).

Yeah - it goes out.

And this is what some fire extinguishers do.

A fire extinguisher like this one sprays special, thick foamy stuff

onto a fire, and that stops oxygen getting to the fire,

and without oxygen, the fire goes out.

Fire doesn't just need oxygen to burn,

it needs something else very important,

and I know a place where we can find lots of this important thing.

The candles are out safely - let's go, experimenters!

Where do you think we're going today?

Nina said we were going to see something important that fire needs.

I think bananas are very important.

Bud, I have a feeling that wasn't what Nina meant.

I've brought you to this huge forest. Does anyone know why?

ALL: No, Nina!

A fire needs two things to burn.

It needs oxygen and it also needs something called a fuel.

A forest like this has got lots of fuel in it,

so let's go see if we can find it!

Hey, Nina, I can see lots of fuel.

Where? Where? What does it look like?

Is it a wild animal?

No, Bud. I should explain exactly what fuel is.

A fuel is something that burns. There are different types of fuel.

The Bunsen burner in my lab uses a gas as its fuel,

and so do some cookers.

Candles use candle wax as fuel,

and cars usually have an oil as their fuel.

But there's another very common fuel

that's growing in the forest right now.

What could it be?

-Trees!

-That's right, trees are made of wood,

and wood is an excellent fuel.

People use it to heat their homes,

and to build camp fires to keep them warm.

But wood will only burn when it's dry.

If it's been raining and the wood's damp, it won't burn,

because fire doesn't like water.

Is that why firemen use water to put out fires?

Yes, firemen use water to put out certain types of fire

because water stops some fuels like wood from burning.

Now back to the lab for our final experiment.

We know that fire is dangerous because it's hot and burns,

but WHY is fire hot? Let's get experimenting!

-Yay!

-OK, I want you to have a look at this mat.

It's very special because it changes colour when it gets warm. Look...

-Cool!

-The heat from my hand has changed the colour of the mat!

Look at the beakers in front of us.

Can you give them a feel

and tell me are they warm or cold?

ALL: They're cold.

So the water and special powder are cold.

But if we mix these together, something interesting might happen.

Let's find out what!

Brilliant.

We all have protective gloves on as we're going to use our hands

to gently mix in the last of the dry bits, OK?

THEY GROAN

-NINA LAUGHS

-What does it feel like?

-Squidgy.

-Disgusting.

-Hee-hee! Is it warm or cold?

-Cold.

-Yuck!

We need to leave the mixture to harden for a while,

and something surprising might happen.

So the mixture of powder and water has gone hard.

Let's feel our tubs and see what it feels like.

-It feels hot.

-Yes, mine too!

The mixture started off cold,

but it's warmed up all by itself.

In science we say the water and powder are reacting with one another

to make heat.

Oh, let's put our tubs onto these mats

because heat makes the mat change colour.

OK...that's good.

So are you ready? And lift them up!

-Yay, it worked!

-Wow!

This has shown that sometimes when different things are put together

they react and make heat.

This is what happens with fire -

fuel and oxygen react to make heat and to make light too.

# Nina And The Neurons. #

Your question was what is fire, and I think we've answered it.

We discovered that fire is a flame or flames that are colourful

and give off heat and light

and fire needs two things to burn - oxygen and fuel.

But the most important thing we learned is that fire is dangerous

because it's so hot,

so you should always, ALWAYS stay away from flames and fire.

-I hope that's answered your question.

-ALL: Yes, thanks, Nina.

-Bye!

-Bye!

# Go, Nina! #

It's been such a great day, man!

The flame on Nina's Bunsen burner sure gave off a lot of light!

I've had a fabby day! I learned to stay away from candles

because they can burn.

It's been a marvellous day,

feeling those beakers get warm all by themselves.

Our day's been bursting with experiments.

-I hope you enjoyed it. See you soon. Bye!

-Bye!
