Round and round and round...

Oh, hello there.

Just playing with my new toy.

It's a spinning top.

The top spins around a pole that goes down through the middle. See?

SHE LAUGHS

-BEEPING

-Oh, I hear a beep, I see a flash,

I wonder what they're going to ask.

-Hi, Nina.

-Hi.

-We've got a question for you.

How can we spin and turn faster?

That's a great question - how can we spin and turn faster?

Spinning around when we're playing is great fun

but how can we do it really fast?

Why don't you come to my lab and investigate?

See you soon, Nina, bye.

Bye. Well, 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.

OK. Today's question is -

how can we spin and turn faster?

Which Neuron will be most useful in helping us find the answer?

ALL: Me! Me! Me! Oh, 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 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!

CHANTING: Go, Felix! Go, Felix!

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

Today's question is - how can we spin and turn faster?

Because spinning is something we feel,

Felix will be helping us but stand by, Neurons.

I have a feeling I may need help from all of you.

I need to get the lab ready before the experimenters arrive.

James loves history.

Amy likes playing games on her tablet.

My dad was a gymnast.

How do we spin and turn faster?

But they both want to know - how can we spin and turn faster?

So today, for one day only, Amy and James become the experimenters.

-Hi, guys.

-Hi, Nina.

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

how can we spin and turn faster?

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

ALL: Whoop whoo! A senses experiment! We're ready, Nina!

First, let's have a look at some sports

that involve spinning, turning or rolling.

Ooh! Look at those spins.

Oh, they must have practised very hard to do that!

Wow, those people were brilliant at spinning and turning.

Let's have a look at some of the different ways

that we can spin and turn.

Can anyone here do a forward roll?

Well, let's get rolling!

Well done, that was brilliant, experimenters.

Rolling forwards is just one of the ways that we can spin and turn

so let's try another.

How about standing up and spinning on the spot?

Ready... Spin!

NINA LAUGHS

I think we should stop now, Nina. I'm feeling a bit dizzy.

My goodness! And stop spinning!

Now, spinning is fun

but it does make you feel a bit dizzy, doesn't it?

-Yes.

-Let's have a look at these over here.

These little models can help us understand something important

about the spinning we were just doing.

So, James, can you spin this figure forward for me?

Just like when you did a forward roll. That's it. Whee!

Brilliant. Let's give him one more round, go for it.

Good spinning, James, thanks very much.

Now look at the pole through its hips.

-Do you see how the model is spinning and turning around the pole?

-Yes.

That's what we do, although we don't have a pole through our hips.

When we do a forward roll, we spin around an invisible spin line.

Oh! An invisible spin line. I like the sound of that.

Let's look at this model.

So this shows what happens when we spin on the spot.

So, Amy, do you want to show us

the spinning around that we were doing earlier? Ooh!

-Where's the pole this time?

-Down the middle.

Yes, the pole goes right down the middle of the body

and the model spins around it.

And because this model spins in a different way to the first model,

the spin line is in a different place.

But we still don't know how we can spin and turn faster

so let's go somewhere really bouncy to find out.

Where do you think we're going today?

-Nina said it was somewhere really bouncy.

-Oh, oh!

-Maybe it's a big bouncy castle!

-Or a big bouncy bed.

Look, everyone. We're here.

-Here's something bouncy - a trampoline.

-Yeah!

So, you asked - how can we spin and turn faster?

So far, we've discovered there are different ways of spinning,

but we always spin around an invisible line.

So we've come here to see Scott who's a trampolinist

and he can spin in lots of different ways.

Let's have a look.

Doing somersaults on a trampoline can be dangerous.

You should never try this at home.

Oh, I love the springy sound of the trampoline.

Boing, boing!

CLAPPING

That's amazing, Scott, thank you.

-Trampolinists can spin in lots of ways, can't they?

-Yes.

Let's watch Scott do some special spins called somersaults.

Ho ho, that is fast! I can hardly keep up.

It is fast, Luke.

These are called tuck somersaults

because the arms and legs are tucked in.

That's brilliant, Scott, thank you.

Can you show us another type of somersault?

-What's different about these somersaults?

-They're straighter.

Yes, the body shape is not tucked in, it's straighter.

These are called lay-out somersaults

because it looks like the person is laying out flat.

Did you notice anything else about these somersaults?

-They're slower.

-They're much slower.

So let's see both of the somersaults again.

So the tuck is faster...

..and the lay-out is slower.

Thank you, Scott.

Whoo!

-FELIX:

-So we've found out that the tucked-in somersault

is quicker than the straight somersault. But why is that, Nina?

That's a very good question, Felix.

Let's do another experiment to find out.

You're both sitting on special spinning disks

and you'll each have two of these in your hands to give you extra weight.

Now I'm going to spin you both round

and first of all I want you to hold your arms out straight

to either side like this and when I tell you,

I want you to pull your arms in like this, OK?

So there's your weights, and there are your weights.

James, you're going to go first.

Hold your arms out straight. That's good.

Here we go!

Hee hee! More spinning.

I love this question.

At least Nina's not doing it this time.

And pull your arms in.

Whoo!

Fantastic, guys. So, what happened when you tucked your arms in?

We went faster.

Yes. What happened when your arms were out straight?

You get slower.

Yes. The reason that happened

is to do with the invisible spin line you were spinning round.

Come with me and find out more.

So, when you were spinning, where do you think the spin line was?

-Down the middle.

-Yes, right down the middle.

Down here.

When your arms were straight, your body weight

and the extra weight were further away

from the invisible line

and this makes you spin more slowly.

But when you tucked your arms in to your bodies,

your weight was all bunched up in the middle

close to the spin line, and this makes you spin faster.

-OLLIE:

-So Scott's tuck somersault was faster

because his body was all scrunched up and not spread out?

Exactly, Ollie.

The tuck somersault is faster

because the body weight isn't spread out.

It's all scrunched up close to the spin line.

And that's how we can spin faster.

-Would you like a go?

-Yes, please!

ALL: Whee!

Aw, really good, guys.

SHE LAUGHS

Oh, that was great fun

but I don't think I'm quite ready for somersaults yet.

# Nina and the Neurons! #

So, your question was - how can we spin and turn faster?

And I think we've answered it.

LUKE: We found out that we can spin and roll in lots of different ways,

but we always spin around an invisible spin line.

-BELLE:

-If our body is stretched out, away from the invisible line,

we will spin more slowly.

OLLIE: But if we scrunch up our body,

keeping our weight as close to the invisible line as possible...

-BUD:

-..We can go faster, whee!

-FELIX:

-Although spinning can make us feel very dizzy.

So don't try to spin too fast.

-So, I hope that that's answered your question.

-Thanks, Nina, bye.

You're welcome, bye.
