In go the oranges. Nice and round.

Oh, hello there. I'm just filling up my fruit bowl.

And here are the bananas.

BEEPING

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

-ALL: Hi, Nina!

-Hi.

-We've got a question for you.

Sometimes the moon is round.

-And sometimes it's banana shaped.

-Why does the moon change shape?

That's a great question.

Why does the moon change shape? Oh, we'll have fun exploring this.

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

ALL: 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, "Why does the moon change shape?"

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

ALL: 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 or 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 Luke.

CHEERING

ALL CHANT: Go, Luke! Go, Luke!

Cool, Nina. I'll be looking out to help you.

Today's question is, "Why does the moon change shape?"

Because the moon is something we see,

Luke, our sight Neuron, will be helping us today.

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

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

Hannah likes dancing.

Rihan loves pineapple ice lollies

and Oliver loves tomato sauce on everything.

They all want to know, why does the moon change shape?

-I love looking at the moon.

-Sometimes it's different shapes.

Why is the moon different shapes?

So today for one day only, Hannah, Rihan

and Oliver become the explorers.

-Hi, guys.

-ALL: Hi, Nina.

Welcome to my workshop and thank you for your great question,

"Why does the moon change shape?"

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

ALL: Whoo-hoo, a senses experiment. We're ready, Nina.

Have a look at these photographs of the moon.

It can be so many different shapes in the sky. This is a new moon.

This is a crescent moon. Looks a bit like a banana.

This is a half moon and this is a full moon.

-So many different shapes.

-My favourite is this one!

HE GROANS

The moon is shaped like this big, round ball

and doesn't change shape.

It just looks like different shapes at different times

and we're going to find out why.

-What do you think the moon is made of?

-I know, it's made of cheese.

That's a lovely idea, Bud.

Some people joke about the moon being made of cheese.

-It's actually made of...?

-ALL: Rock.

Astronauts have actually been to the moon, so we know it's made of rock.

-Now, when do we usually see the moon?

-Night-time.

-Yes.

We see the moon at night.

Our big, round ball is also made of rock so it's a bit like the moon.

Just a lot smaller.

And now I'm going to make the workshop a bit darker.

-Now, it's a little bit harder to see the rock, isn't it?

-ALL: Yes, Nina.

The moon is made of rock.

And we found it harder to see our rock when it was dark and if it

was really dark, like night-time, we wouldn't be able to see it at all.

So how do we see the moon?

Let's see what happens when I shine a light onto our rock.

You can see the rock more clearly now, can't you?

-Yes, there it is, Nina.

-ALL: Yes!

We can see it because the torch is shining a light onto it.

It's lit up.

-And the moon is lit up by the sun.

-What?

You must have that wrong, Nina. I've never seen the sun at night.

Ah-ha. We can't see the sun at night

but it's still out in space lighting up the moon.

Is all of the moon lit by the sun?

Great question. Let's try an experiment.

And I'm going to turn down the lights even more for this.

Oh!

Now this is a beam of light.

And I'm going to use this spray so we can see it even more clearly.

So look carefully.

Remember, Nina is specially trained to do this.

You should never try anything like this yourself.

Look at this.

By using my special spray, we can see the beam of light

-coming from the torch.

-ALL: Oh!

-Now, does the light look straight or bendy?

-Straight.

Yeah, light goes in a straight line.

He-he.

The beam is shining on to our pretend moon.

The light hits this side and lights it up.

But no light is hitting the other side of the moon. So it stays dark.

Light can't bend around corners. So it can only get to one side.

Now we know that the moon is a big, round ball of rock.

We can't see rocks in the dark but we can see the moon

because light from the sun shines on it.

Half the moon is lit up and half is always dark.

Because light travels in straight lines.

Well remembered, Neurons.

We know a lot about the moon. There's still more to find out.

Let's go somewhere we can look at the moon.

Here we go. I can't wait to see where we'll end up today.

Nina said we'll look at the moon.

-Maybe we're going all the way to the moon?

-I can't wait.

-If only it was made of cheese.

-I don't think we're going to the moon.

So far we've found out that the moon is a big, round ball of rock and

we can see it in the dark because light from the sun shines on it.

And we also found out that light travels in straight lines.

Light from the sun only shines on one side of the moon

and the other side is dark.

There's a lot more to find out about the moon. This is a telescope.

What is a telescope, Nina?

Well, Bud, a telescope is something people use to see things

-that are far away.

-Is the moon far away?

Yes, the moon is far away in space. But the moon is actually really big.

But because it's far away, it looks small.

And people use telescopes to take a closer look at the moon.

But it's a bit cloudy here tonight for us to see the real moon.

But I've got some fantastic pictures of the moon here on my tablet.

-So what can you see?

-I can see bumps.

-Some of the moon is dark.

Well spotted, some of the moon is dark.

That's the part the light from the sun can't get to.

Just like we saw in our pretend moon earlier.

But, Nina, why is it sometimes round and sometimes banana-shaped?

Good question, Belle. And I've got a great game that will show us why.

-OK, explorers, what do you think this is?

-Earth.

-That's right.

This is the earth. This is where we live.

-Now, Oliver, you are the moon.

-What a great costume.

And Rihan and Hannah, you are standing in the earth

and will be looking at the moon.

The white side of the moon is the side that's lit by the sun

and the black side is the side that's not lit by the sun.

So it's dark. Now, the moon moves around the earth like that.

Whoo-hoo!

Oliver, you're going

to move around the earth always facing towards the sun.

And you guys are going to see what the moon

looks like in different places.

-So, are you ready for some moon watching?

-ALL: Yes!

Oliver, as the moon, you are in your first position.

Girls, I'd like you to take a look at the moon and then tell me which

of these pictures matches what the moon looks like in this position.

What does he look like? Have a look at all the choices.

Which one do you think it is?

Good girl.

Very good, girls.

Oliver, can you move to your next position, please?

And remember to keep facing the sun.

Excellent.

OK, girls, which one do you think it is?

Excellent. Excellent work.

OK, Mr Moon, next position, please.

Good.

Excellent, good girl.

Fantastic, well done.

So, we've seen that the moon has lots of different shapes but,

-Oliver, you were the moon. Did you change shape?

-No, Nina.

That's right. The real moon doesn't change shape, it's always round.

It just looks like it changes shape.

We can only ever see the side of the moon that is lit up by the sun.

The moon moves around the earth

and that changes how much of it we can see.

It takes the moon a month to go around the earth.

And at different times, it makes different shapes.

# Nina and the Neurons. #

So, your question was, "Why does the moon change shape?"

-And I think we've answered it.

-The moon is lit up by the sun.

But the back of the moon is always dark.

The moon is a big, round ball of rock.

The moon moves around the earth.

And that changes how much of it we can see.

So when we look up at the moon, we see different shapes.

-So I hope that's answered your question.

-ALL: Thanks, Nina. Bye.

You're welcome. Bye.

If you want to know more about the science that's around us,

go to the Nina section on the CBeebies website. Have fun.

# Look at the world before us

# Explore, explore, explore, explore

# We're always on the lookout

-# We're Earth explorers

-O-oh, o-oh

-# We're Earth explorers

-O-oh, o-oh

# We're Earth explorers. #

Exploring is about looking at the world around us,
