# Oh yeah! #

1:00:531:00:55

Oh, hello. I'm just tidying up after an experiment.

1:00:561:01:00

I'll have to stretch up to put this back.

1:01:001:01:02

Oh, there we are.

1:01:021:01:04

COMPUTER BLEEPS

1:01:041:01:06

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

1:01:061:01:11

ALL: Hi, Nina.

1:01:111:01:14

Hi, guys.

1:01:141:01:15

We've got a question for you.

1:01:151:01:18

Why are our backs so bumpy?

1:01:181:01:22

Oh, that's a great question. Why are our backs so bumpy?

1:01:221:01:26

I haven't thought about it. You're right, they're really bumpy.

1:01:261:01:31

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

1:01:311:01:35

ALL: See you soon, Nina.

1:01:351:01:37

Bye!

1:01:371:01:40

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

1:01:401:01:43

OK, Neurons, time to get to work.

1:01:431:01:48

ALL: Neurons at the ready, Nina.

1:02:031:02:06

OK. Today's question is, why are our backs so bumpy?

1:02:061:02:10

Which Neuron will be most useful to help find the answer?

1:02:101:02:13

ALL: Me! Me! Me! Oh, me!

1:02:131:02:16

Will it be fabulous Felix?

1:02:161:02:18

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

1:02:181:02:23

Beautiful Belle?

1:02:231:02:25

I send messages to brain from ear. If there's a sound, I'll help you hear.

1:02:251:02:29

-Lovely Luke?

-For looking and seeing, day or night,

1:02:291:02:33

I'll help you with your sense of sight.

1:02:331:02:36

-Will it be awesome Ollie?

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

1:02:361:02:40

my messages help your sense of smell.

1:02:401:02:43

Or will it be baby Bud?

1:02:431:02:44

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

1:02:441:02:49

It's Felix!

1:02:531:02:54

CHEERING

1:02:541:02:56

ALL: Go Felix! Go Felix!

1:02:561:02:58

Go Felix! Go Felix! Go Felix! Go Felix!

1:02:581:03:01

Go Felix!

1:03:011:03:03

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

1:03:031:03:07

Today's question is, why are our back so bumpy.

1:03:071:03:10

Because we use touch to feel the bumps,

1:03:101:03:13

Felix, our touch neuron, will be helping us today.

1:03:131:03:16

Right, I need to get the lab ready for the experimenters.

1:03:161:03:20

Kai likes balancing, Cara likes hopping, and Rianna loves tennis.

1:03:221:03:27

But they all want to know how our backs are so bumpy.

1:03:271:03:30

So today, for one day only, Kai, Cara and Rianna

1:03:301:03:33

become the experimenters!

1:03:331:03:35

-Hi, guys.

-ALL: Hi, Nina.

1:03:381:03:40

Oh, welcome to my science lab. Come in.

1:03:401:03:43

Now, your question is, why are our backs so bumpy?,

1:03:431:03:47

which is a great question.

1:03:471:03:49

But why do you want to know?

1:03:491:03:52

When we went swimming,

1:03:521:03:53

I noticed that my friend's back was all bumpy.

1:03:531:03:57

And we want to know why.

1:03:571:04:01

We're going to have fun exploring this question.

1:04:011:04:04

For our first experiment, we're using our senses.

1:04:041:04:07

ALL: Whoop-woo! A sense experiment! We're ready, Nina.

1:04:071:04:12

I'd like you to touch the bumps on each other's backs

1:04:121:04:16

and tell me how they feel.

1:04:161:04:18

Kai's feels lumpy.

1:04:201:04:23

Lumpy?

1:04:231:04:25

-Feels like a tortoise shell.

-Well, you're right.

1:04:251:04:28

It does feel quite hard and knobbly, doesn't it?

1:04:281:04:32

The bumps you felt in each other's backs

1:04:321:04:34

are part of your backbone,

1:04:341:04:37

which is also called your spine.

1:04:371:04:40

Now, let's have a look at Mr Skeleton's spine. So where is it?

1:04:401:04:45

The middle.

1:04:451:04:47

That's right. Our spine is in the middle of our skeleton.

1:04:471:04:51

It goes all the way from the top of our neck,

1:04:511:04:55

all the way down to our bottom.

1:04:551:04:57

Now, I'd like you guys to have a feel of Mr Skeleton's spine

1:04:571:05:02

and tell me what it feels like.

1:05:021:05:04

Lumpy.

1:05:041:05:06

-Bumpy and lumpy.

-Yes!

1:05:071:05:10

The spine is lots of little bones,

1:05:101:05:12

a bit like these cotton reels.

1:05:121:05:15

We're going to use these to make a pretend spine.

1:05:151:05:19

So we're going to thread them

1:05:191:05:21

onto this piece of cord like this.

1:05:211:05:24

Whoop!

1:05:241:05:27

OK, let's do it.

1:05:271:05:29

Oh, nice work, guys.

1:05:401:05:43

We've made our very own bumpy spine. Ha-ha!

1:05:431:05:47

Now our real spine is actually a lot like this.

1:05:471:05:50

There's a cord running right down the middle of it

1:05:501:05:53

and it's called our spinal cord. It runs right down the middle

1:05:531:05:57

of our spine, through little holes

1:05:571:06:01

that you can see here.

1:06:011:06:03

Our spinal cord is like a telephone line

1:06:031:06:06

our brain uses to talk to the rest of our body.

1:06:061:06:10

Hello, is that the body? Yes, it's the brain calling.

1:06:101:06:13

I need you to do something.

1:06:131:06:15

The brain is the thing inside our head

1:06:151:06:18

that tells the rest of our body what to do.

1:06:181:06:22

If we want to jump in the air, our brain sends a message

1:06:221:06:26

down our spinal cord to our legs and feet

1:06:261:06:30

to tell them to jump.

1:06:301:06:31

It sounds like the spinal cord is really important, Nina.

1:06:311:06:36

It is, Belle. The little hard bones in the spine

1:06:361:06:39

do a good job of protecting the spinal cord inside.

1:06:391:06:44

But why is there lots of little bones, Nina?

1:06:441:06:47

Good question, Rianna. Yeah, the bumpy spine

1:06:471:06:51

looks very different to the long, straight bone

1:06:511:06:54

in Mr Skeleton's arms and legs, doesn't it? So I think we need to go

1:06:541:06:58

to an exciting place with lots of action.

1:06:581:07:00

-Let's go, experimenters!

-ALL: Yeah!

1:07:001:07:04

I wonder where Nina is taking us.

1:07:071:07:10

Nina said it's somewhere exciting with lots of action.

1:07:101:07:13

It might be a bowling alley!

1:07:131:07:17

Or maybe it's a fairground with lots of brilliant rides whizzing around.

1:07:171:07:22

Look, guys! We're here!

1:07:221:07:24

OK, experimenters.

1:07:241:07:26

We've discovered that our spine is made of lots of bones.

1:07:261:07:30

Abby here is going to help us work out why.

1:07:301:07:34

OK, everyone. Let's try a side bend.

1:07:341:07:37

Ah, yes. All this bending feels marvellous.

1:07:461:07:50

-Ah! Thanks, Abby.

-You're welcome, Nina.

1:08:001:08:03

Ah, that was brilliant fun! All that bending and twisting!

1:08:061:08:10

And what part of our bodies were we bending a lot?

1:08:101:08:14

-Our backs.

-That's right.

1:08:141:08:16

And in what directions did our backs bend?

1:08:161:08:20

Forwards and backwards and side to side.

1:08:201:08:24

Yeah, we can bend our backs forwards, backwards,

1:08:241:08:27

from side to side and all around in a circle.

1:08:271:08:31

And we can only do this

1:08:311:08:33

because our spine is made of all these little bumpy bones.

1:08:331:08:37

They allow our bodies

1:08:371:08:38

to twist and bend and turn, like this.

1:08:381:08:42

Wow, look at how it bends.

1:08:431:08:46

You can see all the bumps that stick out our back when we bend.

1:08:461:08:50

You try.

1:08:501:08:52

-It's really bendy.

-That's a good thing.

1:08:541:08:56

If our spine was just one big long hard bone,

1:08:561:09:00

like this pretend one, then it wouldn't be able to bend.

1:09:001:09:05

Hrrgh!

1:09:051:09:06

And we wouldn't be able to do lots of things,

1:09:061:09:10

like reaching over and picking something up

1:09:101:09:13

or bending over to tie our shoelaces.

1:09:131:09:16

There's another thing our spines do in our brilliant bodies.

1:09:161:09:21

Let's go back to my lab for an experiment.

1:09:211:09:23

OK, first of all, I would like you to simply jump on the spot.

1:09:261:09:30

Let's go for it!

1:09:301:09:32

THEY GIGGLE

1:09:341:09:36

Oh, that was fun.

1:09:381:09:41

OK, tell me how the floor felt underneath your feet

1:09:411:09:44

when you were jumping.

1:09:441:09:46

Hard and a wee bit sore.

1:09:461:09:48

OK, the same thing again,

1:09:481:09:50

but this time we're jumping on these big cushions. Let's go!

1:09:501:09:55

-OK, now how did your feet feel that time?

-Really bouncy.

1:09:591:10:04

Yes, much comfier on the feet and legs.

1:10:041:10:07

This is another reason why our spines are brilliant.

1:10:071:10:11

In between the bony bumps on our spine,

1:10:111:10:14

we have something called discs which act as little cushions.

1:10:141:10:18

And this experiment

1:10:181:10:21

is going to explain why.

1:10:211:10:23

OK, now you each have an egg joined to a little pole.

1:10:231:10:27

What will happen if you bang the bottom of the pole

1:10:271:10:30

against the hard brick?

1:10:301:10:33

-It'll smash.

-Well, let's see.

1:10:331:10:35

OK, when I count to three,

1:10:351:10:38

you're going to hit the bottom of the pole off this hard brick, OK?

1:10:381:10:43

One, two, three, go!

1:10:431:10:45

Oh! Ho-ho-ho!

1:10:481:10:51

Hee-hee-hee! Oh, dear! OK, Kai.

1:10:511:10:54

Let's see if it happens again. Go!

1:10:541:10:57

Oh! Ha-ha-ha!

1:10:571:11:00

Oh, no! The eggs are both smashed!

1:11:001:11:03

We only broke the eggs for our experiment, Bud.

1:11:031:11:07

It's not good to waste food normally.

1:11:071:11:09

OK, now Cara.

1:11:091:11:12

What will happen if we do the same thing again,

1:11:121:11:15

but this time with a little cushion under the egg?

1:11:151:11:18

Don't know.

1:11:181:11:20

OK. Well, let's give it a go.

1:11:201:11:23

Oh!

1:11:231:11:25

It didn't break! Why do you think it didn't break?

1:11:251:11:29

There was a soft cushion underneath.

1:11:291:11:31

Eggs-actly! Ha-ha!

1:11:311:11:34

The soft, squishy cushion protected the egg

1:11:341:11:37

and stopped it breaking.

1:11:371:11:40

And the disks in our spine do the same thing.

1:11:401:11:43

They act like little cushions

1:11:431:11:45

in between all the hard little backbones

1:11:451:11:48

so that when we walk, run or jump in the air,

1:11:481:11:51

the little bones don't bash together and our head stays nice and safe.

1:11:511:11:56

Your question was, why are our backs so bumpy? I think we've answered it.

1:12:011:12:05

Our brilliant backbone, our spine,

1:12:051:12:08

is bumpy because it's made up of lots of little bones.

1:12:081:12:13

This allows us to bend, stretch and move in lots of different ways.

1:12:131:12:17

These little hard bones also protect

1:12:171:12:20

the soft spinal cord

1:12:201:12:22

which our brain uses to talk to our body.

1:12:221:12:25

The soft discs between the bones in our spine

1:12:251:12:29

cushion our body and head when we walk, run or jump up and down.

1:12:291:12:33

So I hope that's answered your question.

1:12:331:12:36

ALL: Thanks, Nina. Bye!

1:12:361:12:38

Bye!

hard, bumpy spine.

1:13:441:13:46

Oh, I've had a brilliant day.

1:13:461:13:48

The exercise class with the bending

1:13:481:13:51

and stretching was great fun!

1:13:511:13:53

Ah, it's been such a great day, man.

1:13:531:13:56

The experiment with the eggs was really smashing. Hee-hee!

Nina investigates why people's backs are so bumpy, with the help of Felix, her touch neuron.

Experimenters Cara, Kai and Rianna visit Nina in her lab and find out that backs feel bumpy because the backbone - or spine - is made up of lots of little hard bones. These protect something called the spinal cord which the brain uses to talk to the rest of the body.

They go to an exercise class and do lots of bendy, stretchy moves. Nina explains that people are able to bend and stretch in lots of different, useful ways because the spine is made up of lots of little bones, not one big, long, hard bone.

Back in the lab, they do a smashing experiment with eggs and discover that there are little soft discs between the bones in the spine. These act as little cushions, stopping the bones from bashing together when people move.
