SHE HUMS

Oh, hello. I'm just tidying up after making these lovely biscuits.

BEEPING

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

BEEPING

-Hi, Nina.

-Hi, guys.

-We've got a question for you.

How are biscuits in a packet made all the same?

That's a great question.

How are biscuits in a packet made all the same?

When we buy biscuits from the shops, they're all the same,

and they taste yummy too. Come down and we'll investigate.

-See you soon, Nina, bye!

-Bye!

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

OK, Neurons, time to get to work.

ALL: Neurons at the ready, Nina.

So, how are biscuits in a packet made all the same?

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 Bud!

-CHEERING

ALL CHANT: Go, Bud! Go, Bud! Go, Bud! Go, Bud! Go, Bud! Go, Bud!

Hooray! Bring on the tasting, Nina!

Today's question is,

how are biscuits in a packet made all the same?

Biscuits are something we taste, so Bud will be helping us.

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

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

Faaizah likes ice cream. Farhan loves playing on the slide.

Biscuits in a packet look the same.

Home-made biscuits are different shapes.

Today, for one day only, they are the engineers.

-Hi, guys!

-BOTH: Hi, Nina!

Welcome, and thanks for your great question.

How are biscuits in the packet made all the same?

To find out, we're going to start by using our senses.

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

We can't have a question about biscuits without tasting some.

I just happen to have made some biscuits today. Shall we try one?

Are they meant to be different shapes and sizes, Nina?

Actually, they were meant to be circles.

They look a bit wonky, don't they? There we go.

Lovely.

Mmm...

They might look funny, but they are yummy.

They all taste good, and they feel and smell the same.

But they look a bit different to these biscuits from shop.

Even the patterns on them match.

I wonder if we could make biscuits a bit more like that?

Let us wash our hands and have a go.

This is biscuit dough.

We are going to make circles of exactly the same size

using these cutters.

Woo!

Oh, this is taking ages! When is it time to eat them?

I don't think it's a good idea to eat dough before it's cooked, Bud.

Cutters down, guys. Now, we can try and make the same pattern.

I think I'll try and make a big N for "Nina"!

OK, let's see how this works.

Oh, I'll try another one.

-They are not exactly the same, are they?

-No, Nina.

-No.

The cutters made the same shape,

but it's difficult getting the patterns the same.

We need something to make this easier, maybe these will help.

There you go.

These are biscuit stamps. I'll show you how they work.

You press them onto the biscuit dough and they make a pattern.

Oh, look, a lion! I like lions especially when they ro-o-oar!

ALL GASP Sorry.

Oh, we've finished! Have a look!

The cutters and the stamps have made them all the same.

We found out that by using a cutter and a stamp,

we can make everything exactly the same shape and pattern.

It's quicker and easier than using our hands.

But, we have only made a few biscuits.

There are hundreds of biscuits in the shops,

so how have engineers solved the problem of making a lot of biscuits

in the same shape quickly?

I think we need to go somewhere noisy to find out.

-Oh, I wonder where we're going today?

-Nina said it was somewhere noisy.

-Not too noisy, I hope.

-I hope there are lots of noises.

-I like being kept busy.

-Well, we're about to find out.

-Do you know where we are?

-In the biscuit factory!

Yes, this is a biscuit factory,

that's why we have to wear these special clothes and these hairnets.

The hairnets make sure that no hairs get into biscuits.

Oh, when do we get to taste the biscuits, Nina?

Bud, we're not here to taste the biscuits,

we are here to find out how these biscuits are made using machines.

So, let see.

What a lot of biscuits! I've never seen so many!

This machine is cutting the biscuits into exactly the same shape,

and stamping the same pattern on them,

just like we did with our cutters and stamps.

-It's much faster, isn't it?

-Yes!

Now, the biscuits will go into an oven to be baked.

Oh, they look so yummy, but they are still not finished.

-What else do they need?

-The middle.

-That's right!

And this is done by another machine.

Do you see how the machine lines up the biscuits,

and adds the middle in exactly the same way?

The tops go on there and our biscuits are finished!

So, to make biscuits quickly and all the same,

engineers have made machines to do it.

Each machine has its own job to do to help make the biscuit.

This is called a production line.

-A what?

-A production line, Bud.

-Really, should listen more.

-That's your job! Hahaha!

Each machine in the factory is in a line.

They all do their own job over and over again.

The biscuit goes along the line, and each machine adds something.

Why can't one machine do everything? Let's do an experiment find out.

So, how are biscuits in a packet made all the same?

We found out that factories use a production line of machines,

that each do a different job, and we're going to find how that works.

I've got a box here,

and I'd like you guys to make one exactly the same,

using the things in front of you.

Try and make it quickly,

and finish your box before I pass you the next one.

-OK?

-Yes, Nina.

Three, two, one, go!

The boxes are coming too fast. They can't keep up.

-OK, stop there! Oh, that was hard, and it took a long time.

-Yes, Nina.

Let's try it a different way.

This time, we're going to make our very own production line,

doing one job each.

I'll put on the strawberry sticker,

Farhan can stick on the blue rectangle,

and Faaizah, you do the red circle.

-OK, ready?

-Yes, Nina.

-Three, two, one, go!

Oooh!

You're doing brilliantly, guys!

Well done, we've made some lovely boxes on our production line!

-Was it easier with just one job to do?

-Yes, Nina!

Building a machine that does everything is difficult,

especially if you're making something with many parts.

Engineers solve this problem by making lots of machines in a line.

Lots of things are made in production lines like cars,

televisions and computers.

# Nina and the Neurons! #

Your question was, how are biscuits in a packet made all the same?

I think we have answered it.

Engineers made machines that use cutters and stamps

to quickly make the same shape over and over again.

A production line is a line of machines doing different jobs.

Machines on a production line make things the same,

and much quicker than we could. I hope that answers your question.

-Thanks, Nina, bye!

-You're welcome, bye.

I've had a fabby day!

There were biscuits here, there, and everywhere!

Yummy!

I really enjoyed myself today.

Nina's biscuits may have looked funny, but they smelled delicious.

I've had a brilliant day!

Who would have thought

biscuit-making machines would have been so noisy!

Engineers help to build the world around us.

They make things work and use science to solve problems.

See you again soon, bye!

ALL: Bye!
