0:00:530:00:54

Oh, hello. Oh, I'm just doing a very important experiment to find out

0:00:570:01:02

how long you can dip a biscuit into hot tea before it turns to mush.

0:01:020:01:07

Oh. That must have been too long!

0:01:070:01:10

BEEPING

0:01:100:01:12

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

0:01:120:01:17

ALL: 'Hi, Nina!'

0:01:210:01:25

Hi, guys.

0:01:250:01:26

We've got a question for you.

0:01:260:01:28

Where does the sand on the beach come from?

0:01:280:01:32

That's a brilliant question! Where does the sand on the beach come from?

0:01:320:01:37

Well, why don't you all come down to my lab

0:01:370:01:40

and we'll do some experiments to investigate?

0:01:400:01:43

ALL: 'See ya soon, Nina! Bye!'

0:01:430:01:47

Bye!

0:01:470:01:49

Well, I'm going to need some help to answer this one

0:01:490:01:52

and I know just who to ask. OK, Neurons, time to get to work.

0:01:520:01:56

ALL: Neurons at the ready, Nina.

0:02:120:02:14

OK. Today's question is, "Where does the sand on the beach come from?"

0:02:140:02:18

Which Neuron will be most useful to help find the answer?

0:02:180:02:22

ALL: Me! Me! Me! Oh, me!

0:02:220:02:26

Will it be fabulous Felix?

0:02:260:02:28

I can help so very much if you need the sense of touch.

0:02:280:02:32

Will it be beautiful Belle?

0:02:320:02:34

I send messages to brain from ear.

0:02:340:02:36

If there's a sound, I'll help you hear.

0:02:360:02:39

Will it be lovely Luke?

0:02:390:02:40

For looking and seeing, day or night,

0:02:400:02:43

I'll help you with your sense of sight.

0:02:430:02:45

Will it be awesome Ollie?

0:02:450:02:47

If it's pongy or whiffy but you can't tell,

0:02:470:02:50

-my messages help your sense of smell.

-Or will it be baby Bud?

0:02:500:02:54

Sour, salty, bitter or sweet, I'm your taste buddy whenever you eat!

0:02:540:02:59

-It's Luke!

-Yes!

0:03:020:03:05

ALL: Go, Luke! Go, Luke! Go, Luke! Go, Luke! Go, Luke! Go, Luke!

0:03:050:03:11

Go Luke!

0:03:110:03:12

Cool, Nina. I'll be lookin' out to help ya.

0:03:120:03:16

Today's question is, "Where does the sand on the beach come from?"

0:03:160:03:20

We see the sand on the beach, so Luke, our seeing Neuron, is going to be helping.

0:03:200:03:25

I better get the lab ready before the experimenters arrive.

0:03:250:03:28

Remy loves ballet, Anessa loves singing

0:03:300:03:33

and Emma loves the fairground,

0:03:330:03:35

but they all want to find out more about sand.

0:03:350:03:38

So today, for one day only, they become experimenters!

0:03:380:03:44

Hi, guys.

0:03:450:03:47

ALL: Hi, Nina.

0:03:470:03:49

Welcome to my lab. Come to the desk.

0:03:490:03:52

You asked a brilliant question -

0:03:520:03:55

where does the sand on the beach come from?

0:03:550:03:58

Why do you want to know?

0:03:580:04:00

I like making sandcastles on the beach.

0:04:000:04:04

-But we don't know where the sand comes from.

-Sand is interesting.

0:04:040:04:09

For our first experiment, we'll use our sense.

0:04:090:04:12

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

0:04:120:04:17

OK, experimenters, pop these blindfolds on

0:04:170:04:20

because you're just going to use your sense of touch.

0:04:200:04:23

I have three bowls in front of me.

0:04:230:04:26

One contains sand, one contains salt and one contains sugar.

0:04:260:04:32

I want you to feel inside each of them and try and guess which is sand.

0:04:320:04:38

Here's the first one.

0:04:380:04:40

-Salt!

-Sugar!

-Sand!

0:04:400:04:41

-Ooh, feels grainy and a bit gritty. Little bit hard?

-Yeah.

0:04:410:04:46

Here's our next bowl.

0:04:460:04:48

-Sand!

-Sand, yeah.

-No, no, it must be sugar,

0:04:480:04:53

And here's the last one. Feel what it's like.

0:04:530:04:57

-Salt!

-This is sand! Sand.

-We can't decide which was sand.

0:04:570:05:01

Why don't you take your blindfolds off and now can you tell me

0:05:010:05:06

which one is sand?

0:05:060:05:07

ALL: That one.

0:05:070:05:09

This one! Yeah. Sand looks a bit different from the others.

0:05:090:05:14

So the sand, salt and sugar all FELT the same

0:05:140:05:18

but sand LOOKS different.

0:05:180:05:20

My microscope will let us take an even closer look at some sand.

0:05:200:05:25

-What do the grains of sand look like now?

-Rocks.

-Ah.

0:05:250:05:31

Under the microscope, the tiny grains of sand look like rocks or pebbles.

0:05:310:05:37

-Yeah.

-So, from this experiment, we found out that

0:05:370:05:41

sand, like salt and sugar, is made of lots of tiny grains.

0:05:410:05:45

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

0:05:450:05:49

I think we need to do another experiment.

0:05:490:05:52

For this experiment, I'm going to make a mess!

0:05:540:05:58

Now I'm going to add some warm water.

0:06:110:06:13

Give it a good stir.

0:06:190:06:22

Something is happening to the salt and sugar but, to see it,

0:06:220:06:27

we need to pour the water back out again.

0:06:270:06:30

So, the sand is still in the beaker.

0:06:410:06:45

But where's the salt and sugar gone?

0:06:450:06:47

-In the water.

-In the water! Absolutely right!

0:06:470:06:52

This experiment has shown us that salt and sugar

0:06:520:06:55

seem to disappear when you put them in water. We call this dissolving.

0:06:550:07:00

But the sand is different. It doesn't dissolve in water,

0:07:000:07:05

which is just as well. If it did, it'd disappear into the sea

0:07:050:07:09

and there would be no sand on the beach to make sandcastles.

0:07:090:07:13

So we know that sand is made of lots of tiny, hard grains.

0:07:130:07:17

But what are the grains made of?

0:07:170:07:20

I think we need to investigate a little further.

0:07:200:07:23

In fact, we need to do some digging!

0:07:230:07:26

Let's go, guys!

0:07:260:07:28

Where do you think we're going?

0:07:340:07:36

Nina said we would have to do some digging.

0:07:360:07:39

I don't like the sound of that!

0:07:390:07:42

Nina might get soil under her fingernails! Ugh!

0:07:420:07:47

I think we're here.

0:07:470:07:48

And I recognise that smell!

0:07:480:07:51

Look!

0:07:510:07:52

Wow! Look at those waves! Aren't they amazing?

0:07:580:08:02

ALL: Yes.

0:08:020:08:04

They make a brilliant crashing noise, too, Nina!

0:08:040:08:07

They certainly do, Belle.

0:08:070:08:10

We've come to the beach to find out more about sand.

0:08:100:08:13

We need to find some buried treasure! Arr!

0:08:130:08:17

X marks the spot, me hearties!

0:08:170:08:20

So let's get digging! Whoo-hoo!

0:08:200:08:23

-I think it's up there.

-Over there?

-Yeah.

0:08:290:08:33

I mean that's where the cross is.

0:08:330:08:37

Where that orange thing is.

0:08:370:08:39

Oh, I love the smell of the salty sea.

0:08:420:08:45

But when are they going to find the treasure?!

0:08:450:08:48

Ooh, look at this, girls.

0:08:480:08:50

ALL: Ooh!

0:08:500:08:51

Do you think that's an X? ALL: Yeah!

0:08:510:08:54

Let's move the wood and start digging!

0:08:540:08:58

I just found it!

0:08:580:08:59

Brilliant. OK, girls. Here's your spades.

0:08:590:09:02

-I think it's...

-Guys, guys, guys!

0:09:040:09:07

ALL: Wow!

0:09:070:09:10

Let's open it.

0:09:110:09:12

ALL GASP

0:09:160:09:18

Wow, look!

0:09:180:09:19

Wow!

0:09:190:09:21

Nina's found a diamond!

0:09:210:09:23

It's not a diamond, Bud. It's quartz.

0:09:230:09:26

Quartz. That's a funny-sounding word, Nina.

0:09:260:09:30

It is a bit funny-sounding, Belle. I quite like it.

0:09:300:09:33

So do I. Quartz. Quartz. Quartz. Quartz!

0:09:330:09:38

So quartz is a special type of rock.

0:09:380:09:41

Can you remember what the sand grains looked like under the microscope?

0:09:410:09:46

-ALL: Yeah.

-They looked like rocks.

0:09:460:09:50

That's right. They looked a bit like this quartz rock, didn't they?

0:09:500:09:55

-Yes, Nina.

-That's because the sand on most beaches

0:09:550:09:59

is mostly made from quartz.

0:09:590:10:01

-But how's it made, Nina?

-To answer that, we need to go back to the lab

0:10:010:10:06

for one final experiment.

0:10:060:10:08

THEY CHEER

0:10:080:10:11

OK. WE know that sand comes from the beach,

0:10:170:10:20

but what else do we always find at the beach?

0:10:200:10:23

Smelly seaweed.

0:10:230:10:24

Noisy seagulls?

0:10:240:10:25

Yummy ice cream!

0:10:250:10:27

ALL: The sea!

0:10:270:10:29

That's right, the sea!

0:10:290:10:31

This experiment will show us that the sea is very important

0:10:310:10:35

in making sand.

0:10:350:10:36

I need to put my protective gloves on. You guys already have yours on.

0:10:360:10:41

-We also need our safety goggles on to protect our eyes.

-Yes!

0:10:410:10:46

It's very important to protect our eyes

0:10:460:10:49

when doing experiments in Nina's science lab.

0:10:490:10:52

OK, we're going to use these pebbles from the beach

0:10:520:10:56

to try and break up these rocks into tiny pieces like sand.

0:10:560:11:00

Wow! This experiment sounds like fun!

0:11:000:11:04

Bud, it's not a good idea to break things normally.

0:11:040:11:07

this is part of a controlled experiment. Let's do it!

0:11:070:11:11

Whoo! That was hard work!

0:11:350:11:37

But we did it. We used the pebbles to break the rocks

0:11:370:11:43

into tiny grains, like sand.

0:11:430:11:45

This happens to rocks in the sea.

0:11:450:11:48

Remember the waves crashing on the rocks at the beach?

0:11:480:11:52

ALL: Yes, Nina.

0:11:520:11:54

When the waves crash on the rocks, the rocks and pebbles bash together,

0:11:540:12:00

along with other things, like sea shells,

0:12:000:12:04

and after a long, long time,

0:12:040:12:06

and lots of bashing and banging together,

0:12:060:12:09

the rocks break up into sand.

0:12:090:12:12

Your question was, where does sand come from?

0:12:160:12:19

I think we've answered it.

0:12:190:12:21

We discovered sand is made of lots of tiny grains.

0:12:210:12:25

These grains don't dissolve in water, and are mostly made of quartz.

0:12:250:12:31

The waves in the sea smash the rocks against one another

0:12:310:12:35

and over a long time, these rocks break up into lots of grains of sand!

0:12:350:12:40

I hope that's answered your question. ALL: Thanks, Nina.

0:12:400:12:44

ALL: Bye! Bye!

0:12:440:12:46

It's been a marvellous day.

0:13:410:13:43

I really enjoyed feeling those grains of salt, sugar and sand.

0:13:430:13:48

I've had a fabby day!

0:13:480:13:51

Finding the buried treasure was the BEST!

0:13:510:13:54

Oh, I've had a brilliant day.

0:13:540:13:56

Nina and the children made a smashing noise

0:13:560:13:59

breaking those rocks up!

0:13:590:14:02

Our day's been bursting with experiments.

0:14:020:14:05

I hope you've enjoyed it. See you soon!

Scientist Nina and her young experimenters discover the amazing ways that things can change and react in the everyday world.

Nina investigates where the sand on the beach comes from, with the help of Luke, her sight neuron. Experimenters Annessa, Emma and Renee visit Nina in her lab. Using their senses, they discover that sand is made of lots of tiny hard grains which look a bit like rocks under Nina's microscope. Next, Nina does an experiment to show that, unlike grains of sugar or salt, sand doesn't dissolve or seem to disappear in water.

Then they all go to the beach for a treasure hunt and find a beautiful rock called quartz. Nina explains that sand is mostly made from quartz. But how does this happen? Back in the lab, the children use pebbles to break some special soft rocks up into grains like sand. Nina explains that the waves in the sea turn quartz rocks into sand by bashing them together.
