# Doo-doo-doo... #

Oh, that's strange. Hello. Just trying to turn my lamp on

but it doesn't seem to be working, I wonder what's wrong.

Oh... Silly me.

Forgot to plug it in.

That's better.

BEEP

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

-BOTH: Hi, Nina!

-Hi, guys.

We've got a question for you.

-Where does electricity come from?

-That's a great question.

Where does electricity come from?

We need electricity to make lots of things work

but where does it come from?

Why don't you come down to my workshop to investigate?

-See you soon, Nina! Bye!

-Bye.

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, where does electricity come from?

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 Belle!

-ALL:

-Go, Belle. Go, Belle. Go, Belle. Go, Belle. Go, Belle.

Brilliant. I'm all ears, Nina.

Today's question is, where does electricity come from?

Because electrical things in our homes sometimes make a noise,

Belle will be helping us. But standby, Neurons,

I may need some help from all of you.

Right, I need to get the workshop ready before the Engineers arrive.

Faye likes singing. Eliza like spaghetti.

And they want to know about electricity.

How does it get to my house?

How is it made?

So today, for one day only, Faye and Eliza become the Engineers.

-Hi, Faye. Hi, Eliza.

-BOTH: Hi, Nina.

Welcome to my workshop. Thanks for your great question,

where does electricity come from?

To find out the answer, we'll start by using our senses.

ALL: Whoo-whoo! A senses experiment! We're ready, Nina.

First, we're going to play a little game.

I have some things here from the workshop.

We've got a mug, a fan,

a pencil, hairdryer, stapler, and smoothie maker.

I'd like you guys to put these ticks next to the ones you think

need electricity to work. Go, go, go!

Good.

Well done, you've got them all right. Fantastic.

The fan, the hairdryer and smoothie maker all need electricity to work.

-How did you know?

-They all have plugs.

-Yes, that's right.

We get electricity in our homes from plugs in the wall.

The electricity moves down the wire

and into the smoothie maker to make it work.

Shall we plug them in to check they work?

-Yeah.

-Lovely.

Yay, it's working!

How about the hairdryer?

Oh, what a noise!

Ooh, delightful. Oh, lovely.

The hairdryer's definitely working, too. And what have we got here?

The smoothie maker.

SMOOTHIE MAKER WHIZZES

Oh! Have a look at this. Normally, we can't see electricity.

This machine lets us see what happens

when electricity moves through the air.

The electricity is going to jump from here to here.

Can I ask you guys to stand behind the safety screen?

That's right, Nina's been specially trained to do this.

Never play with electricity yourself.

I'll turn the lights down.

Now watch closely as I turn it on.

ELECTRICITY BUZZES

Ha-ha-ha! And that's electricity moving.

Come back and I'll turn the lights back up.

So, we've learnt that electricity makes things in our homes work.

But we still don't know where it comes from.

We need to take a trip to a special station to find out. Let's go.

Where do you think we're going today?

Nina said we were going to a station.

Oh, oh, oh, maybe it's a train station.

Brilliant! Choo-choo!

Well, it looks like we've reached our stop.

Here we are at a power station.

A power station is where they make electricity

and inside this big tube is where electricity is actually made.

I'll show you what's inside on here.

This bit in the middle is called a magnet.

-Do you know what a magnet is?

-Yes, it sticks to metal.

-You're right.

A magnet? Like people put on their fridges, Nina?

Yes, they're like the magnets people put on their fridges.

But this is a lot bigger. And I've got some magnets here.

N, I, N, A

-spells...?

-BOTH: Nina!

But that's not the only clever thing that magnets can do.

Magnets can also make electricity.

How, Nina?

The magnet is in the middle of some circles of wire

and it's spinning round and round

and as that magnet spins round, it makes electricity.

This power station actually makes enough electricity for a whole city.

Oh! That's a lot of electricity, Nina.

Let's go somewhere quieter to find out more.

We are going to make our very own electricity,

just like the power station does downstairs.

Remember, you should never try this yourself at home.

Electricity is dangerous.

I've made one of these for each of us.

If you have a look inside, you can see the magnets

that will spin round. And on the outside, lots of circles of wire.

And these are just like the machines downstairs but a lot smaller.

To show that we really are making electricity,

we've attached them to these light bulbs.

If those light bulbs light up, we know that we've made electricity.

OK, it's time to see if it works.

Let's see if we can spin the magnet inside the wire fast enough

to make enough electricity to light up the light bulbs.

OK, three, two, one, go!

You can do it.

The lights have come on! Yay! We've made electricity!

ALL: Hurray!

Well done, girls.

This is how the power station makes electricity, too.

But their magnet and wire is much bigger so it can make a lot more.

We've just made a tiny, tiny amount of electricity here,

so small that it's safe to be near.

But we must remember that much more electricity comes into our homes,

so we should always be very, very careful.

Oh! Do you see what has happened

since we've stopped spinning the magnets?

The light has gone off.

And that's because the magnets have stopped moving.

Magnets need to keep moving to make electricity.

I wonder how this power station keeps the magnets moving

all the time. Let's find out.

You asked, where does electricity come from?

We've discovered that electricity can be made

by spinning a magnet around inside circles of wire.

We also found out that magnets need to keep moving

to make electricity. But what keeps the magnet moving?

This power station uses water and there's lots of it, isn't there?

Yes, lots.

So let's do an experiment.

In front of us here we have some water wheels.

What do you think will happen if we pour some water on to them?

They'll get very wet, obviously, Nina.

Yes, they will get wet, Felix. But that's not all. What else?

-It will spin around.

-OK, well, let's see.

OK.

Yay, you're right, it's spinning!

And that's because as the water pours onto it,

it catches in these ridges and pushes the wheel round.

This power station uses water in exactly the same way.

The water from up here is poured down big pipes.

It spins a big wheel and that wheel makes the magnet spin round.

Because there is lots of water here,

it can keep the magnet spinning for a long time.

-And that means...?

-Lots of electricity.

-You are right.

Water and electricity are very dangerous together

but this power station makes sure they don't touch.

There are other ways to keep the magnets spinning

to make electricity. Some power stations use water like this one,

and some use steam and some wind.

It takes a lot of effort to make electricity

so we shouldn't waste it.

We should always turn things off if we're not using them.

Your question was, where does electricity come from?

I think we've answered it.

We found out that engineers make electricity by spinning

a magnet inside circles of wire.

Magnets are kept spinning at this power station using water.

-I hope that's answered your question.

-BOTH: Thanks, Nina.

Ooh.

That's the electricity working.

It's been such a great day, man. It was electric.

I've had a brilliant day.

Inside the power station was the noisiest!

It's been a marvellous day.

I liked it when everyone made their own electricity.

That was very clever.

And remember, 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!
