NINA MAKES CAR NOISES

Oh, hello. I'm just experimenting with this car.

And here comes the Nina-mobile.

Can she make it round the corner without skidding? Yeah! Woo-hoo!

The Nina-mobile has won!

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

-Hi, Nina.

-Hi, guys.

-We've got a question for you.

-How does a car go round corners?

-That's a great question.

How does a car go round corners?

Moving cars takes clever engineering.

Come down to my workshop and we'll 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 does a car go round corners?

Which Neuron will be most useful to help 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 Belle.

ALL: Go, Belle. Go, Belle. Go, Belle. Go, Belle.

Brilliant. I'm all ears, Nina.

Today's question is - how does a car go round corners?

Because cars can be noisy and loud,

Belle, our hearing Neuron, will be helping us.

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

I need to get the workshop ready before the engineers arrive.

Elliott likes pudding. Lewis loves playing with his action figures.

I can make my toy car go round corners.

I've seen my dad turn the steering wheel.

So, today, for one day only, Lewis and Elliott become the engineers.

-Hi, Lewis. Hi, Elliott.

-BOTH: Hi, Nina.

Welcome to my workshop and thanks for your great question,

how does a car go round corners?

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

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

First, we'll have a look at these cars.

Real cars have engines inside to make them move,

but we'll be the engines for our cars, so let's get pushing.

THEY MAKE CAR NOISES

Brrrm! Come on, Neurons. ALL: Brrm! Vroom!

Now let's give them a push and let go and tell me

what direction the cars go in.

-Hey.

-They go straight.

That's right, but what if the road changes direction like this?

So here's the car going straight. Oh, dear, what should we do?

-Turn round the corner.

-That's right. To stay in the road,

we need to be able to change the direction of the car.

Now, let's have a look at the wheels.

-So, what way are they pointing?

-Forward.

That's right, they're pointing forward

-But if I just change that. What way are they pointing now?

-Sideways.

They're pointing that way, they're pointing left.

So, Lewis, can I ask you to move the car and see what happens.

All the way round the road. Push it all the way. Very good.

And if I just change the wheels, what way are they pointing now?

That way, Nina.

That's right, they're pointing right.

OK, Elliott, now try driving the car. Go, go, go.

Push it all the way round. Brilliant.

The car moves the same way the wheels are pointing.

So, if the wheels are pointing left, the car goes to the left,

and if the wheels are pointing right, the car goes to the right.

If we want to turn the car and go round corners,

we need to turn the wheels.

Engineers call this steering

and they invented a steering wheel to make it work.

Wa-hey! I'm steering left and I'm steering right!

-How does a steering wheel move the wheels, Nina?

-Good question, Felix.

To find out,

we need to visit some of the most exciting cars in the world.

Let's hit the road, engineers.

Oh, goody, I love this bit. I wonder where Nina is taking us.

Nina said we're visiting some of the best cars in the world.

Maybe it's dodgem cars at the funfair!

No funfair, but I do see a very special car.

Your question was, how do cars go round corners?

So far, I've discovered that engines make cars move and to move

round corners, we need to change the way the wheels are pointing.

Engineers call this steering and cars have a steering wheel.

But how does a steering wheel work?

We've come to see some amazing cars to find out. Take a look at this.

Wow! What an amazing car!

Thank you! This is an old-style racing car. What do you think of it?

It's cool, Nina.

Racing cars are powerful and noisy, as you could hear.

-Did you see the wheels changing direction?

-BOTH: Yes.

That's because the driver was turning the steering wheel.

Racing cars go round corners really fast,

so engineers need to make sure they have the best possible steering.

So let's go and have a look at some newer cars. This way.

We're trying to find out how a car goes round corners

and we just saw a driver turn a steering wheel to

change the direction the wheels were pointing.

But how does the steering wheel work?

Let's get pedalling to investigate.

OK, engineers, this is what you've got to do -

turn your steering wheel the way I point my flag.

-OK?

-On your marks, get set, go!

ALL: Come on, engineers!

Good job, guys, you're nearly there.

-Yay!

-ALL: Hooray!

-You're both great drivers and so good at steering.

-How did it feel?

-It was great fun, Nina.

Let's have a look at the engineering of your steering.

The engineering of the steering! That rhymes.

This is how a steering wheel makes the wheels of a car turn.

The steering wheel joins this rod here which moves the wheels.

-They're joined together by a cog.

-Cog, that's a nice word.

Now, this is a model of a cog. Cogs are usually round

and they have pointy bumps on the outside called teeth.

The teeth on the cog fit onto the teeth on the rod that the

wheels are connected to.

When the steering wheel turns, the cog turns

and when the cog turns, the wheel rod is moved left or right.

And this makes the wheels move. It's very clever engineering.

But how do the cogs change which way the wheels are pointing?

I've got a great experiment we can try back at the workshop.

Now this is a model of the bottom of a car.

-What bits are the same as the cars we saw earlier?

-The cogs.

Yes, and the wheel rod.

If we change the direction of the wheel rod,

we change the direction of the wheels.

-But, can you see if there's anything missing?

-A steering wheel.

Yes, and we need the steering wheel to change

the direction of the wheels. I'll just attach it.

Look, the steering wheel has a cog on the end.

That's right, Luke, and the cog fits into teeth on the wheel rod.

Now, why don't you try the steering wheel and tell me what happens.

On you go, Elliott.

Lovely, now Lewis.

-This is like a real car.

-What's the steering wheel doing?

It's moving the wheels.

Yes, the steering wheel is joined to the wheel rod by a cog.

When we turn the steering wheel, the cog turns

and moves the wheel rod left and right.

It's this movement that changes the direction of the wheels.

# Nina and the Neurons! #

So, your question was, how does a car go round corners?

I think we've answered it.

We discovered that to go round corners,

cars need to change the way their wheels point.

Engineers invented a steering wheel which is joined to

the wheels by a rod and a cog.

This rod and cog turn when the steering wheel turns

which moves the wheels in the same direction,

pointing the car where we want it to go.

-I hope that's answered your question.

-BOTH: Thanks, Nina. Bye.

You're welcome. Bye.

I've had a brilliant day hearing the car engine roar. Brrrm! Brrm!

Ah, it's been such a great day, man. All that whizzing in go-karts.

It's been a marvellous day, learning about cogs,

rods and steering wheels. Super.

Remember, engineers help build the world around us.

They make things work and use science to solve problems.

-See you again soon. Bye!

-ALL: Bye!
