0:00:03 > 0:00:07# If you've got a question And you don't know where to go
0:00:07 > 0:00:11# Ask Nina for some help Cos she's got a science show
0:00:11 > 0:00:15# She makes sense of our senses By helping her fans
0:00:15 > 0:00:17# By doing her experiments With potions and with bangs. #
0:00:17 > 0:00:19Touch your tongue!
0:00:19 > 0:00:21Fingers!
0:00:21 > 0:00:22Eyes! Ears!
0:00:22 > 0:00:23Nose!
0:00:23 > 0:00:26# Every day we use our senses
0:00:26 > 0:00:30# Wherever we may go. #
0:00:30 > 0:00:31Tongue.
0:00:31 > 0:00:33Fingers.
0:00:33 > 0:00:34Eyes. Ears
0:00:34 > 0:00:36Nose.
0:00:36 > 0:00:41# Nina and the Neurons Find out what you need to know
0:00:41 > 0:00:44# Luke helps us with our eyes And Felix with our touch
0:00:44 > 0:00:48# Ollie sniffs out smells Belle hears so much

0:01:05 > 0:01:07# Oh, yeah! #
0:01:07 > 0:01:09Hello! I've had a great idea today.
0:01:10 > 0:01:15I want to show you some lovely views of the city and the countryside.
0:01:15 > 0:01:17Let's see what we can see.
0:01:17 > 0:01:20Oh, there's the Science Centre.
0:01:20 > 0:01:22And the car park.
0:01:22 > 0:01:27Oh, and there's some river. And the Science Centre again.
0:01:27 > 0:01:30The views are great but I want to see more.
0:01:30 > 0:01:34The Science Centre is much bigger than me so I can't see past it.
0:01:34 > 0:01:37For a better view, we need to get higher
0:01:37 > 0:01:41so it's lucky we have this tower here.
0:01:42 > 0:01:46This tower is 127 metres tall.
0:01:46 > 0:01:48That's 80 times taller than me.
0:01:48 > 0:01:53When we get to the top, seeing over things shouldn't be a problem.
0:01:57 > 0:02:02If you look down, you can see we're moving away from the ground.
0:02:02 > 0:02:05I hope you're not scared of heights.
0:02:05 > 0:02:06Oh!
0:02:06 > 0:02:11Wow! Oh, you really do get great views from up here.
0:02:11 > 0:02:15You can see for miles around. You can see the whole city.
0:02:15 > 0:02:17And the hills as well.
0:02:20 > 0:02:21Right down the river.
0:02:21 > 0:02:24Do you see the cars in the distance?
0:02:24 > 0:02:27On the bridge they look really tiny.
0:02:27 > 0:02:32You can see loads of places, even though they're really far away.
0:02:32 > 0:02:35You couldn't see most of them from the ground. Look!
0:02:35 > 0:02:38The Science Centre. When I was next to it,
0:02:38 > 0:02:43there was no way we could see over it. But from here, it looks small
0:02:43 > 0:02:46and you can see over it really easily.
0:02:53 > 0:02:56- BLEEPING - Oh, someone has a question for me.
0:02:56 > 0:02:58I'd better see who it is.
0:03:03 > 0:03:07I hear a bleep, I see a flash I wonder what they're going to ask.
0:03:10 > 0:03:16Hello, Nina. My name's Tanuka and I've got a question for you.
0:03:16 > 0:03:20Why are things so small when they're far away?
0:03:20 > 0:03:24What an interesting question! I know what you mean.
0:03:24 > 0:03:29- We'll have to investigate this. I'll see you soon. Bye.- See you soon.
0:03:29 > 0:03:31Bye.
0:03:32 > 0:03:37I think we'll need help to answer this one. And I know who to ask.
0:03:37 > 0:03:40OK, Neurons, time to get to work.
0:03:55 > 0:03:57ALL: Neurons at the ready, Nina!
0:03:57 > 0:03:59OK, Tanuka's question is -
0:03:59 > 0:04:03why are things so small when they're far away?
0:04:03 > 0:04:06Which Neuron will help us find the answer?
0:04:06 > 0:04:08ALL: Me!
0:04:10 > 0:04:12Will it be Fabulous Felix?
0:04:12 > 0:04:16I can help so very much If you need the sense of touch.
0:04:16 > 0:04:18Will it be beautiful Belle?
0:04:19 > 0:04:23I send messages brain to ear, If there's a sound I'll help you hear.
0:04:23 > 0:04:25Will it be Lovely Luke?
0:04:25 > 0:04:29Looking and seeing, day or night I'll help with your sense of sight.
0:04:29 > 0:04:32Will it be Awesome Ollie?
0:04:32 > 0:04:34If it's pongy or whiffy but you can't tell
0:04:34 > 0:04:37my messages help your sense of smell.
0:04:37 > 0:04:40- Or will it be Bud? - Sour, salty, bitter or sweet
0:04:40 > 0:04:44I'm your taste buddy whenever you eat.
0:04:44 > 0:04:45BLEEPING
0:04:47 > 0:04:50- It's Luke!- Yes!
0:04:50 > 0:04:52NEURONS CHANT: Go, Luke! Go, Luke!
0:04:57 > 0:05:01Cool, Nina. I'll be looking out to help you.
0:05:01 > 0:05:06We want to find out about how things look, so Luke will be helping us.
0:05:09 > 0:05:12OK, then, let's go.
0:05:53 > 0:05:57Here's Tanuka, her mum and her gran, from Newcastle.
0:05:57 > 0:06:01Today, for one day only, they are...
0:06:01 > 0:06:05the Experimenters!
0:06:11 > 0:06:13OK, now, Tanuka's question was -
0:06:13 > 0:06:17why do things that are far away look so small?
0:06:17 > 0:06:21I think we'll need to do some experiments to find the answer.
0:06:21 > 0:06:25Luke is waiting to help us. Aren't you, Luke?
0:06:27 > 0:06:28Ready, Luke?
0:06:28 > 0:06:33It's my big moment. Standing by, ready to send lots of messages.
0:06:34 > 0:06:39But I thought the family were going to meet me here. I can't see them.
0:06:39 > 0:06:40Can you?
0:06:40 > 0:06:43Oh, I can hear someone laughing.
0:06:43 > 0:06:47I think that's Tanuka and her family.
0:06:47 > 0:06:49HELLO!
0:06:52 > 0:06:54I think it is.
0:06:56 > 0:07:00Hello. Hi, everyone.
0:07:00 > 0:07:04You must be Tanuka. Nice to meet you. Thank you for your question -
0:07:04 > 0:07:09why do things that are far away look so small? Very good question.
0:07:09 > 0:07:13What kinds of things have you seen
0:07:13 > 0:07:17- that look small when they're far away?- An aeroplane.
0:07:17 > 0:07:18Oh. And what else?
0:07:18 > 0:07:20A helicopter.
0:07:20 > 0:07:22And a helicopter?
0:07:22 > 0:07:25And those things really are big.
0:07:25 > 0:07:27Yes.
0:07:27 > 0:07:31I think I know the very experiment that would help us.
0:07:31 > 0:07:33Yes.
0:07:34 > 0:07:37OK, for this experiment, we have two boxes.
0:07:37 > 0:07:39Mum, can you do me a favour?
0:07:39 > 0:07:44Can you take this box... ..Now, no peeking you, into what's in the box.
0:07:44 > 0:07:47..and pop that up the back for me? Lovely.
0:07:47 > 0:07:50We have a box here as well, Tanuka.
0:07:50 > 0:07:54But I don't want you to peek behind us to see what Mum's doing.
0:07:54 > 0:08:00Why don't you open the box and see what's inside?
0:08:02 > 0:08:03Oh! What is it?
0:08:03 > 0:08:05A teddy bear.
0:08:05 > 0:08:09It's a teddy bear. Oh, it's lovely, as well.
0:08:09 > 0:08:12Why don't we sit him on there, facing that way?
0:08:12 > 0:08:15Can you do that for me?
0:08:15 > 0:08:18We're all going to wander over here.
0:08:18 > 0:08:23- Are you ready yet, Mum?- Yes. - Come on over.
0:08:23 > 0:08:28Mum's here. OK, now... we can all turn round.
0:08:29 > 0:08:32Now, what can you see, Tanuka?
0:08:32 > 0:08:36- I can see teddy bears. - You can see teddy bears.
0:08:36 > 0:08:38Oh, that teddy's looking smart
0:08:38 > 0:08:43- with his tartan ribbon.- I bet he feels very soft to touch.
0:08:43 > 0:08:47- Have you ever measured with your fingers before?- No.
0:08:47 > 0:08:49Well, you close one eyes...
0:08:49 > 0:08:52Or you can cover one eye like that as well.
0:08:52 > 0:08:57Close one eye...look at your object and put your fingers up.
0:08:57 > 0:09:01And then close your fingers around the object.
0:09:01 > 0:09:04Both teddies appear to be the same size.
0:09:04 > 0:09:10- Mum, could you bring your teddy over for us, please?- OK.- Thank you.
0:09:10 > 0:09:16Now, let's watch as this teddy at the back comes towards us.
0:09:17 > 0:09:19What's happening?
0:09:19 > 0:09:22It's getting bigger.
0:09:22 > 0:09:25Can we measure this teddy with our fingers?
0:09:25 > 0:09:30Oh, I don't know about you, but my fingers can't stretch that far.
0:09:30 > 0:09:35- I think we need to measure him with hands.- Yes.- One...- One...
0:09:35 > 0:09:37- two...- Two hands.
0:09:37 > 0:09:41- Three hands. - Oh, three and a half hands.
0:09:41 > 0:09:43So he's really big.
0:09:43 > 0:09:45That experiment has shown us
0:09:45 > 0:09:49the bigger the distance between yourself and an object,
0:09:49 > 0:09:51the smaller the object looks.
0:09:51 > 0:09:55But when the object, like the teddy, comes towards you,
0:09:55 > 0:09:58it gets bigger and you can see its real size.
0:09:58 > 0:10:01Wow-ee! Look at that.
0:10:01 > 0:10:05Mum's teddy's much bigger than Tanuka's.
0:10:05 > 0:10:09They only look the same size because the big teddy was further away.
0:10:09 > 0:10:12I really like measuring things.
0:10:12 > 0:10:16We should measure more things. Would you like to come on a trip?
0:10:16 > 0:10:21- I promise I'll have you all back by tea time.- Yes.- Excellent.
0:10:39 > 0:10:41Oh, wow!
0:10:41 > 0:10:43Look at that!
0:10:47 > 0:10:52- It's the Angel of the North. - It looks teeny from up here.
0:10:52 > 0:10:55Let's measure it with our fingers.
0:10:56 > 0:11:00- It's only this big.- Yeah.
0:11:00 > 0:11:03It looks brilliant even though it's very small.
0:11:03 > 0:11:06Have you any ideas where we should go next?
0:11:06 > 0:11:09Let's get close to it.
0:11:09 > 0:11:12Good idea. Let's go, everyone.
0:11:27 > 0:11:29Oh, wow!
0:11:29 > 0:11:34When you're this close, you can really see how big it is.
0:11:34 > 0:11:36Shall we measure it? Yes.
0:11:36 > 0:11:41Oh, can you...? It's nearly too big for my fingers.
0:11:42 > 0:11:46Why don't we try hands again? You're very good at that.
0:11:46 > 0:11:48One...
0:11:48 > 0:11:49two...
0:11:49 > 0:11:52It's just massive.
0:11:52 > 0:11:56Wow! Look at the size of it when we're up close.
0:11:56 > 0:11:58It's massive.
0:11:58 > 0:12:02You'll need more than one hand to measure that lot.
0:12:22 > 0:12:26- I've had such a good day with you guys. Have you?- Yes.
0:12:26 > 0:12:32I must be going now, I'm afraid. So take care of yourselves. Bye!
0:12:32 > 0:12:34- Bye.- Bye.
0:12:44 > 0:12:45NEURONS: Oh!
0:12:45 > 0:12:49# It's been a busy, busy day
0:12:49 > 0:12:51# Questions answered Experiments done
0:12:51 > 0:12:54# We've all used our senses in so many ways
0:12:54 > 0:12:58# Tell me, Neurons what have you done today? #
0:12:58 > 0:13:01Well, I definitely worked the hardest today.
0:13:01 > 0:13:03I had loads of messages to send
0:13:03 > 0:13:07about how objects look small when they are far away
0:13:07 > 0:13:10but large when they are near you.
0:13:11 > 0:13:14Well, I was working hard too, you know.
0:13:14 > 0:13:18There was all that reaching out with fingers and hands
0:13:18 > 0:13:21to measure the teddies and the Angel of the North.
0:13:21 > 0:13:24There were loads of sounds to keep me busy.
0:13:24 > 0:13:30I had to listen out for Tanuka when she was far away in the park.
0:13:30 > 0:13:34We've had a bit of an easy day, haven't we, Bud?
0:13:34 > 0:13:37Yes. But I've still had a fabby time.
0:13:44 > 0:13:49Well, that was great fun. I hope you've had a sensational time too.
0:13:49 > 0:13:51Bye!
0:13:51 > 0:13:53ALL: Bye!
