0:00:530:00:54

Oh, hello! It started raining when I was walking to the lab today,

0:00:570:01:01

but I had my waterproof jacket with me, which kept me nice and dry.

0:01:010:01:07

-Oh, it suits you, Mr Skeleton!

-BEEPING

0:01:070:01:11

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

0:01:110:01:15

-ALL: Hi, Nina!

-Hi, guys!

-We've got a question for you, Nina.

0:01:180:01:23

-Why do we have skin?

-That's a great question!

0:01:230:01:27

We've all got skin, but what does it do?

0:01:270:01:30

Why don't you come down to my lab and we'll investigate.

0:01:300:01:34

-ALL: See you soon, Nina! Bye!

-Bye!

0:01:340:01:37

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

0:01:370:01:42

OK, Neurons! Time to get to work!

0:01:420:01:44

-ALL: Neurons at the ready, Nina!

-OK.

0:02:010:02:05

Today's question is - why do we have skin?

0:02:050:02:08

Which Neuron will help us find the answer?

0:02:080:02:11

ALL: Me! Me! Me Me!

0:02:110:02:14

Will it be fabulous Felix?

0:02:140:02:17

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

0:02:170:02:21

Will it be beautiful Belle?

0:02:210:02:23

I send messages to brain from ear,

0:02:230:02:25

if there's a sound, I'll help you hear.

0:02:250:02:28

Will it be lovely Luke?

0:02:280:02:29

For looking and seeing, day or night, I'll help you

0:02:290:02:33

-with your sense of sight.

-Will it be awesome Ollie?

0:02:330:02:36

If it's pongy or whiffy but you can't tell,

0:02:360:02:39

I'll help you with your sense of smell.

0:02:390:02:41

-Or will it be baby Bud?

-Sour, salty, bitter or sweet?

0:02:410:02:45

I'm your taste buddy whenever you eat.

0:02:450:02:47

It's Felix!

0:02:510:02:53

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

0:02:550:02:59

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

0:03:020:03:06

So, why do we have skin?

0:03:060:03:08

Because our lovely, soft skin is something we touch,

0:03:080:03:12

I think Felix is the neuron helping us today.

0:03:120:03:16

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

0:03:160:03:19

Right, I need to get the lab ready before the experimenters arrive!

0:03:190:03:23

Jordan likes fish fingers, Harry likes spaghetti

0:03:230:03:28

and Kieran loves computer games.

0:03:280:03:30

But they all want to know why they have skin,

0:03:300:03:34

so today, Jordan, Harry and Kieran become the experimenters!

0:03:340:03:38

-Hi, guys!

-Hi, Nina!

-Welcome to my science lab! Come on in!

0:03:410:03:46

Now, your question is,

0:03:460:03:47

"Why do we have skin?" Which is a great question,

0:03:470:03:51

-but why do you want to know?

-We have lots of skin.

0:03:510:03:54

But we want to know why.

0:03:540:03:56

Well, our brilliant bodies certainly have a lot of skin

0:03:560:04:00

and there must be a good reason why.

0:04:000:04:02

We need to do some investigating to find out.

0:04:020:04:05

For our first experiment, we'll use our senses.

0:04:050:04:08

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

0:04:080:04:12

-Now, who knows where our skin is?

-All over our body.

-That's right.

0:04:120:04:18

And if we look in our hair, there's even skin under there too.

0:04:180:04:23

We call this our scalp, and the fact we have skin

0:04:230:04:29

over our bodies is important in understanding what skin is for.

0:04:290:04:33

I'm setting you a challenge to find out more.

0:04:330:04:36

I'll get the things we need from the storeroom.

0:04:360:04:39

-I wonder what Nina is looking for.

-I'm sure you know what these are.

0:04:400:04:44

-Backpacks.

-That's right. They're backpacks

0:04:440:04:47

that you maybe use for school. There you go.

0:04:470:04:50

So, have a look inside them and take everything out.

0:04:500:04:54

-Oh!

-A sandwich!

0:05:030:05:06

And an apple.

0:05:060:05:07

Pumps...

0:05:080:05:10

-Wow!

-A banana and a sandwich! This is making me really hungry!

0:05:100:05:16

I'll take these, thank you very much. Thank you, Jordan.

0:05:160:05:21

Now, your challenge is to pick everything up

0:05:210:05:26

and take it back to the storeroom in one go.

0:05:260:05:29

-Why are you dropping things?

-Because we have too many things.

0:05:440:05:49

Now, careful with the apple.

0:05:510:05:53

Ooh!

0:05:530:05:55

Oh! Poor apple!

0:05:550:05:58

I was able to carry everything over quite easily.

0:05:580:06:01

-Why was that?

-Because everything was inside the bags.

0:06:010:06:05

Exactly! And I didn't drop a thing! OK, boys.

0:06:050:06:09

Put everything back on the desks.

0:06:090:06:11

You see, it's a lot easier to carry things if you use a rucksack.

0:06:110:06:15

And our skin is like a rucksack for our brilliant bodies.

0:06:150:06:20

Underneath our skin are lots and lots of different things.

0:06:200:06:24

-Can you tell me what some of them are?

-Bones and heart.

0:06:240:06:27

-Blood and lungs.

-That's right.

0:06:270:06:31

And our super skin is like a big bag that keeps all of these

0:06:310:06:35

important parts together and protects them.

0:06:350:06:38

But, what other cool stuff does our skin do?

0:06:380:06:40

Well, to find out the answer, we need to muck about a bit,

0:06:400:06:45

and I know just where. Let's go, experimenters!

0:06:450:06:48

-Off we go for another adventure.

-Nina said we can muck about!

0:06:540:06:57

Hooray! Playtime!

0:06:570:07:00

And I thought this was a serious experiment.

0:07:000:07:02

-How can we muck about here?

-I don't know, Luke.

0:07:020:07:06

But sharpen your senses, everyone. We're here!

0:07:060:07:10

Right, experimenters.

0:07:100:07:12

Now we're going to pretend that this car is our body.

0:07:120:07:15

Our body? But it's filthy, Nina.

0:07:150:07:19

That's right. But for this experiment, that's a good thing.

0:07:190:07:23

In fact, we could do with making it even dirtier.

0:07:230:07:26

-Yes!

-That's what I meant by "mucking about". Ready, everyone?

0:07:260:07:30

ALL: Yes!

0:07:300:07:32

-I love the sound of all that sloshing water.

-That should do nicely.

0:07:430:07:50

Now that we've got it really dirty,

0:07:500:07:52

let's get inside and go through the car wash. Come on!

0:07:520:07:56

Ooh, at least the inside's nice and clean.

0:07:560:07:59

What a fabulous noisy noise! Brrrrrrrr!!!

0:08:030:08:08

Look at all that water pouring down the windows!

0:08:080:08:12

Amazing!

0:08:120:08:14

There lots of water outside, but none of it's getting inside

0:08:140:08:17

and making us wet.

0:08:170:08:19

That's because all the doors and windows are shut tight.

0:08:190:08:23

-The car is all sealed up.

-A seal pup?! Where? Wow!

0:08:230:08:29

-Arrup! Arrup!

-Not a seal pup! The car is sealed up!

0:08:290:08:34

And it's just what our skin does for our brilliant bodies!

0:08:340:08:39

Our skin is waterproof, so it keeps water out

0:08:390:08:42

when we're in the bath, the shower, even walking in the rain.

0:08:420:08:46

And our skin also keeps out dirt and germs too.

0:08:460:08:49

Germs are tiny, invisible things that can make us feel ill.

0:08:490:08:53

This is why we must always wash our hands before eating -

0:08:530:08:56

to stop germs spreading into our mouths.

0:08:560:08:59

There! Our car is nice and clean again!

0:08:590:09:03

We found out earlier it's our skin's job to keep our insides in.

0:09:030:09:06

A bit like a bag for a body.

0:09:060:09:08

It's also brilliant at keeping out water, dirt and germs.

0:09:080:09:13

But our super skin does other important jobs too.

0:09:130:09:17

-So let's go back to the lab for our final experiment.

-ALL: Yeah!

0:09:170:09:21

Let's have a closer look at our skin through our magnifying glasses!

0:09:240:09:29

-Oh... So, what can you see?

-I can see hairs.

-That's right.

0:09:290:09:35

We don't just have hair on our heads. We have hair on our skin too.

0:09:350:09:40

It's all over our bodies.

0:09:400:09:42

In fact, the only places we don't have hair are on our lips

0:09:420:09:48

and on the palms of our hands. Magnifying glasses down!

0:09:480:09:52

Let's all rub our forearms with the balloons

0:09:520:09:55

and see what happens to those little hairs.

0:09:550:09:58

Then lift the balloon a tiny bit above your skin

0:10:010:10:05

and see what happens to the little hairs.

0:10:050:10:08

-Wow! Would you look at that!

-What's happening to the little hairs?

0:10:080:10:12

-They're standing up.

-That's right.

0:10:120:10:15

We made them stand up by rubbing them with a balloon

0:10:150:10:17

to create something called static electricity.

0:10:170:10:20

But sometimes the hairs on our bodies stand up all by themselves

0:10:200:10:26

and we call this having goosebumps. Have you ever had goosebumps?

0:10:260:10:29

-Yes.

-How were you feeling when you got them?

0:10:290:10:32

-Cold.

-Feeling cold? That's right.

0:10:320:10:35

When we feel cold, the little hairs on our skin stand up on end.

0:10:350:10:41

They do this to trap warm air, which is near our skin,

0:10:410:10:44

and stop it from escaping. That makes us feel warmer.

0:10:440:10:46

So, our skin helps us to stay warm when we're cold.

0:10:460:10:51

But it can also help us if we feel hot.

0:10:510:10:53

I need you to put your goggles on to protect your eyes,

0:10:530:10:56

because I'm going to spray your face with a little bit of water.

0:10:560:11:01

Here I come. Are you ready?

0:11:010:11:03

Very good. OK, Harry?

0:11:030:11:06

Are you ready?

0:11:080:11:10

He-he-he-he-he!

0:11:110:11:13

-That must feel SO refreshing!

-How does that water feel?

-Nice and cool.

0:11:130:11:19

Have you guys ever been in a really warm place,

0:11:190:11:22

-or been running around so much you felt really hot?

-Yes, Nina.

0:11:220:11:27

When that happens, our body needs to cool down quickly.

0:11:270:11:31

-Can anyone think how it does this?

-Cos it makes you sweat.

-That's right!

0:11:310:11:37

Our skin releases little drops of sweat

0:11:370:11:39

through things called sweat glands. It's this sweat

0:11:390:11:43

that takes the heat away from our body

0:11:430:11:45

and cools us down. So, our super skin helps us to cool down

0:11:450:11:49

when we're hot and helps us warm up when we're cold. Brilliant!

0:11:490:11:54

Your question was - why do we have skin? And I think we've answered it.

0:11:590:12:04

It's like a protective bag for our brilliant bodies,

0:12:040:12:07

which holds all of our insides in place.

0:12:070:12:11

It also keeps out dirt and germs that could make us feel ill.

0:12:110:12:15

And it's waterproof, so it keeps water out when we're in the bath.

0:12:150:12:19

It's also important in making sure we're not too hot or too cold.

0:12:190:12:24

The little hairs on our skin stand up when we're cold

0:12:240:12:28

and trap warm air to warm us up.

0:12:280:12:30

And when we're hot, our skin makes sweat to cool us down.

0:12:300:12:34

-So I hope that's answered your question.

-ALL: Thanks, Nina. Bye!

0:12:340:12:38

You're welcome! Bye!

0:12:380:12:40

-all those things without a bag.

-It's been such a great day!

0:13:480:13:52

I loved looking through the magnifying glass at all those hairs!

0:13:520:13:58

Remember, everyone's body is different,

0:13:580:14:01

but they're all brilliant. See you again soon! Bye!

Nina investigates why people have skin, with the help of Felix, her touch neuron. Experimenters Ciaran, Harry and Jordan visit Nina in her lab and find out that skin is like a rucksack for the body, keeping the insides safe and in place.

Then they visit a car wash and discover that skin is also good at keeping things out of bodies, such as dirt and germs. And skin is waterproof too, which is a good thing when you have a bath!

Back in the lab, they use their magnifying glasses to see that people have lots of tiny hairs in their skin. Nina explains that when people are cold, the tiny hairs stand up, helping to trap warm air and warm them up. Skin also helps to cool people down when they are too hot by making them sweat.
