00:00If you've got a question and you don't know where to go

00:08Ask Nina for some help, cause she's got a science show

00:11She makes sense of her senses while helping all her fans

00:14By doing her experiments with potions and with bats

00:17Touch her tongue, fingers, eyes, ears, nose

00:23Nina and the neurons find out what you need to know

00:26Nina and the neurons find out what you need to know

00:29He helps us with our eyes and Felix with our touch

00:32Ollie sniffs our snuff and sends some bells she hears so much

00:35But it's Ollie's brother, he helps us with our taste

00:38Then he knows the neurons and they're coming to your place

00:41Touch her tongue, fingers, eyes, ears, nose

00:47Nina and the neurons find out what you need to know

00:50Nina and the neurons find out what you need to know

00:53Oh yeah!

00:54Oh hello!

00:57I'm just examining my rock collection

00:59I'm rather proud of it actually

01:01It's amazing what can be found underground

01:03Oh!

01:10I hear it, I see a flash

01:11I wonder what they're going to ask

01:13Hi Nina!

01:17Hello!

01:18We've got a question for you Nina

01:20Why are we told to drink milk?

01:22That's a great question

01:23Why are we told to drink milk?

01:26Oh!

01:26Why don't you come down to the lab and we'll do some experiments to investigate

01:29See you soon Nina!

01:32Bye!

01:34Well I'm going to need some help to answer this one

01:36And I know just who to ask

01:38Okay neurons, time to get to work

01:40Okay, today's question is

02:02Why are we told to drink milk?

02:03Now which neuron do you think will be most useful in helping us find the answer?

02:07Me, me, me, me

02:09Will it be Fabulous Felix?

02:12I can help so very much if you need the sense of touch

02:15Will it be Beautiful Belle?

02:18I send messages to Brain from ear

02:20If there's a sound I'll help you hear

02:22Will it be Lovely Look?

02:24For looking and seeing, day or night

02:26I'll help you with your sense of sight

02:28Will it be Awesome Ollie?

02:31If it's Pony or Wiffy but you can't tell

02:33My messages help your sense of smell

02:35Or will it be Baby Bud?

02:37Sour, salty, bitter or sweet?

02:40I'm your taste buddy whenever you eat

02:42It's Bud!

02:46Yicky!

02:49Go Bud!

02:50Go Bud!

02:51Go Bud!

02:52Go Bud!

02:54Go Bud!

02:56Go Bud!

02:56Give me a taste of the action, Nina!

03:00Today's question is why are we told to drink milk?

03:03Now I've chosen Bud to help me because milk is something we drink and taste

03:07Right, I need to get the lab ready before the experimenters arrive

03:10Lily loves kittens

03:14Her friend Casey loves spaghetti bolognese

03:17But they both want to find out why we're told to drink milk

03:20So today for one day only

03:22Lily and Casey become the experimenters

03:26Hi, Nina!

03:29Welcome to my science lab

03:30Come in!

03:32Now you asked

03:34Why are we told to drink milk?

03:37Why do you want to know?

03:38Because my mummy's always telling me to drink milk

03:41I like orange juice better

03:42Well, I like milk and orange juice

03:45And apple juice

03:47And grape juice and pineapple juice

03:49That's right Bud, there are lots of lovely drinks

03:52So I wonder why your parents want you to drink milk in particular

03:55I think we need to investigate to find out more

03:58And for our first experiment, we're going to use our senses

04:01Whoop, whoop, a senses experiment

04:04We're ready, Nina

04:06Okay, who can tell me what colour milk is?

04:09White

04:10White

04:10White, yeah

04:12Milk is white

04:13Now, does milk smell of anything?

04:16Have a smell

04:17It smells like milk

04:18Yeah

04:20It smells delicious

04:23But it's really hard to describe

04:25Now, what about the taste?

04:28Taste is like milk

04:30It's like a creamy taste

04:32Of course, orange juice comes from oranges that grow on trees

04:36But where does milk come from?

04:38Cows

04:38That's right

04:39Milk often comes from cows

04:41But we can drink milk from other animals

04:43Like sheep's milk and goat's milk

04:46And all these different milks have something in common

04:48They have something special in them that we can't see

04:51It's called calcium

04:53Have you ever heard of calcium before?

04:55No

04:55Well, I think calcium might be the reason that you're told to drink milk

04:59So come this way

05:00Now we're all wearing our safety goggles for this experiment

05:05And I've also got my safety gloves on

05:08Now this is calcium

05:12And this calcium comes from the ground

05:14Doesn't look much like milk, does it?

05:17No, Nina

05:18What does it look like?

05:20It looks silvery

05:22Yeah

05:22Like little silvery hard lumps

05:25And this is what calcium looks like on its own

05:28Now we don't normally see it like this

05:30It's normally in other things

05:32Like milk

05:33Like milk

05:35And then it looks very different

05:37Now would you like to see me make some calcium disappear?

05:41Yes, Nina

05:43Nina's going to do a magic trick!

05:51What can you see happening?

05:53It's fizzing

05:54Bubbles are getting bigger and then popping and making the steam come out

05:59So the water made the hard piece of silvery calcium fizz up

06:02And the water and calcium have joined together

06:05And made this cloudy white liquid

06:08So what colour is water normally?

06:11No colour

06:12That's right, water doesn't have a colour

06:14So this white colour must come from the calcium

06:18But I said I'd make the calcium disappear, didn't I?

06:23Yeah

06:23OK

06:24I'm just going to add a little bit of vinegar

06:28And then give it a little stir

06:33Ta-da!

06:36It's like magic!

06:38It's science, bud

06:39But it's still pretty cool, isn't it?

06:41Yeah

06:41So calcium is hard and silvery grey

06:45But then when it's mixed with things like water

06:48It changes and can even turn invisible

06:51So we know that there's calcium in milk

06:53Even though we can't see it

06:55But how does it get there?

06:56Oh, I know somewhere

06:59A bit dark and spooky

07:00That might help us find out

07:02Let's go, experimenters

07:04Here we go

07:10I can't wait to see where we'll end up today

07:13Nina said it would be dark

07:15And spooky

07:17And there'd be goblins and witches and...

07:20Don't be silly, bud

07:22Nina wouldn't take us anywhere scary

07:25I've brought you to these caves to see some amazing science

07:29And we're going to go down under the ground to see it

07:32You're not afraid, are you?

07:33No

07:34Oh, excellent

07:36And you guys look like very brave experimenters

07:38So come on, let's go in

07:40Oh, it feels rather cool down here

07:54That's because the sun doesn't shine underground, Felix

07:57Oh, wait, did you hear something?

08:00It's water dripping

08:02Yes, and if we follow the sound of the dripping water

08:05Then we should find what we're looking for

08:07This way

08:08Wow, cool

08:16Oh, wow

08:17Oh, what is it?

08:19Is it scary?

08:21Can I lick?

08:22Oh, bud, they're not scary at all

08:24They're called stalactites and stalagmites

08:28And they're found in underground caves like these

08:31And they have calcium in them

08:33Now, remember I was telling you earlier

08:35That calcium is found in the ground

08:37Now, the ground is usually below us

08:40But as we've come down into these caves

08:42The ground is now above us and below us

08:46Stalactites and stalagmites are made

08:50When special water from the ground above us

08:53Drips into these caves

08:55And the water has calcium in it

08:57Because it's travelled through the ground

08:59To get here, picking up calcium on the way

09:02Over many, many years

09:04The special water dries up

09:06Leaving these amazing hard pointy things

09:10Now, do they remind you of something?

09:12Giant teeth that haven't been brushed very well

09:15Yeah, they do look a bit like dirty giant teeth

09:19Giant teeth? Oh no!

09:23They just look like giant teeth, little bud

09:26Don't you want to see them?

09:28Wow! They're amazing!

09:31Our teeth are a bit like stalagmites and stalactites

09:34Because they have calcium in them too

09:36Our bodies use calcium to make our teeth

09:39And our bones strong and hard

09:41Is that why we're told to drink milk?

09:44Exactly!

09:45But how does the calcium get into the milk?

09:48Ah! Well, I know an experiment that will help us answer this question

09:51So let's go back to the lab for our final experiment!

09:54So here we have two beakers

10:00Now in this beaker is tap water

10:02And in this beaker is special water that you might find in the ground

10:06Now can you tell them apart?

10:09No!

10:09Oh, well I think you might be able to after the experiment

10:13So goggles on please

10:14Now we never drink out of experiment beakers as that could be dangerous

10:20So I want you to pick up your special blowing tubes

10:23And blow into the beaker of water

10:26Okay, stop there guys

10:37Now what's happened to the water?

10:39Mine's gone all whitish

10:41And mine's just stayed the same

10:43That's right

10:44Now this has gone all whitish

10:46Because this water from the ground has calcium in it

10:50And blowing air into the calcium water made it change and turn white

10:55And Lily, your water, the tap water, has stayed the same

10:59Because it's got no calcium in it

11:00But how does calcium get into our milk?

11:03Well, all the fruits and vegetables that we eat

11:06Come from trees and plants like this one

11:09Now where do these grow?

11:11They come from ground

11:12Yes, plants come from the ground

11:14So they drink water from the ground around them

11:17Now remember when we visited the caves

11:19We found out that water from the ground has calcium in it

11:23So what do you think happens when plants drink water from the ground?

11:27The plants drink out calcium too

11:29That's right

11:30So almost all of the fruit and vegetables that we eat have calcium in them

11:34But what about the milk?

11:37It doesn't come from a plant

11:38It comes from a cow

11:40Good point, bud

11:42Ah, so what do cows eat?

11:45Grass

11:45Ah, yeah

11:47Grass grows in the ground

11:49So the grass also drinks up water with calcium in it

11:52So cows get calcium from the grass

11:55And then make lovely creamy milk with it

11:57So your question was

12:01Why are we told to drink milk?

12:03And I think we've answered it

12:04First we found out that milk has something called calcium in it

12:08And calcium is found in the water in the ground

12:11And because plants drink this water

12:14Calcium is found in lots of the fruits and vegetables that we eat

12:17And because cows and other animals eat plants like grass

12:21Calcium is found in the milk they make too

12:24So we're told to drink milk because it has lots of calcium in it

12:28Which our bodies need to make healthy bones and teeth

12:31But we also discovered that calcium is in lots of other foods too

12:35So I hope that's answered your question

12:37Thanks, Nina

12:38If you want to know more about the science that's all around us

13:14In the lab

13:15In the lab

13:16Go, Nina

13:16In the lab

13:18We see a popping steam and smoke

13:21We need protection, don't we, folks?

13:24We always put our safety first

13:28We do experiments in the lab

13:33In the lab

13:34Go, Nina

13:34Ah, it's been such a great day, man

13:38Seeing Nina make the calcium change colour was cool

13:42I've had a fabby day

13:45Going down into those exciting caves

13:47It's been a marvellous day

13:49It felt quite cold underground

13:51But the stalagmites and stalactites were fascinating

13:54Oh, I've had a brilliant day

13:56Hearing all about how calcium gets into our food

14:00Our day's been bursting with sensational experiments

14:04I hope you've enjoyed it
