0:00:57 > 0:00:59SHE LAUGHS
0:00:59 > 0:01:03Oh, hi, there. I'm just back from holiday. I had a great time.
0:01:03 > 0:01:06But I've got to sort everything out for my washing.
0:01:06 > 0:01:09Jeans go into the dark clothes pile.
0:01:09 > 0:01:12Coloured tops go in here.
0:01:12 > 0:01:15And white things go into this pile.
0:01:15 > 0:01:18I do wish there was a quicker way to sort different things.
0:01:18 > 0:01:20BEEPING
0:01:20 > 0:01:25I hear a beep, I see a flash, I wonder what they're going to ask.
0:01:28 > 0:01:31- ALL: Hi, Nina.- Hi, guys.
0:01:31 > 0:01:33We've got a question for you.
0:01:33 > 0:01:37How do our suitcases get on the right plane at the airport?
0:01:37 > 0:01:38Great question.
0:01:38 > 0:01:41How do our suitcases get on the right plane at the airport?
0:01:41 > 0:01:45And I've just come back from holiday, so I'd love to know how.
0:01:45 > 0:01:48Come to my workshop and we'll investigate.
0:01:48 > 0:01:51ALL: See you soon, Nina! Bye!
0:01:51 > 0:01:52Bye!
0:01:52 > 0:01:56I'm going to need some help to answer this one,
0:01:56 > 0:01:57and I know just who to ask.
0:01:57 > 0:02:00OK, Neurons, time to get to work.
0:02:15 > 0:02:17ALL: Neurons at the ready, Nina.
0:02:17 > 0:02:19OK. Today's question is,
0:02:19 > 0:02:22how do our suitcases get on the right plane at the airport?
0:02:22 > 0:02:27Which Neuron will be most useful to help us find the answer?
0:02:27 > 0:02:30ALL: Me! Me! Me! Oh, me!
0:02:30 > 0:02:33Will it be fabulous Felix?
0:02:33 > 0:02:36I can help so very much, if you need the sense of touch.
0:02:36 > 0:02:38Will it be beautiful Belle?
0:02:38 > 0:02:43I send messages to brain from ear. If there's a sound, I'll help you hear.
0:02:43 > 0:02:45Will it be lovely Luke?
0:02:45 > 0:02:47For looking and seeing, day or night,
0:02:47 > 0:02:50I'll help you with your sense of sight.
0:02:50 > 0:02:51Will it be awesome Ollie?
0:02:51 > 0:02:54If it's pongy or whiffy, but you can't tell,
0:02:54 > 0:02:58- my messages help your sense of smell. - Or will it be baby Bud?
0:02:58 > 0:03:03Sour, salty, bitter or sweet, I'm your taste buddy, whenever you eat!
0:03:07 > 0:03:08It's Felix!
0:03:08 > 0:03:10CHEERING
0:03:10 > 0:03:15Go, Felix! Go, Felix! Go, Felix! Go, Felix! Go, Felix!
0:03:15 > 0:03:18Go, Felix! Go, Felix!
0:03:18 > 0:03:21Marvellous. A little touch can mean so much, Nina.
0:03:21 > 0:03:23Today's question is,
0:03:23 > 0:03:26how do our suitcases get on the right plane at the airport?
0:03:26 > 0:03:29Since we move a suitcase with our hands,
0:03:29 > 0:03:32Felix, the touch Neuron, will be helping us.
0:03:32 > 0:03:35But stand by, Neurons, I may need help from all of you.
0:03:35 > 0:03:39I need to get the workshop ready before the Engineers arrive.
0:03:41 > 0:03:46Joe likes going to school. Lewis loves cars. Maisie likes ballet.
0:03:46 > 0:03:49I took a suitcase on holiday.
0:03:49 > 0:03:52I don't take the suitcase on the plane.
0:03:52 > 0:03:53Where does it go?
0:03:53 > 0:03:55So, today, for one day only,
0:03:55 > 0:03:58Joe, Lewis and Maisie become the Engineers!
0:04:03 > 0:04:05- Hi, guys.- ALL: Hi, Nina.
0:04:05 > 0:04:08Welcome to my workshop. Thanks for your great question -
0:04:08 > 0:04:12how do our suitcases get on the right plane at the airport?
0:04:12 > 0:04:15To find out the answer, let's start by using our senses.
0:04:15 > 0:04:20Whoo-whoo! A senses experiment! We're ready, Nina!
0:04:20 > 0:04:23Oh, and there's my suitcase that I had on holiday.
0:04:23 > 0:04:26I should move it out of the way.
0:04:26 > 0:04:27SHE GRUNTS
0:04:27 > 0:04:28Oh, dear. Oh!
0:04:28 > 0:04:32I need to find a better way to move this heavy suitcase.
0:04:32 > 0:04:35Can you see anything that might help me?
0:04:35 > 0:04:38What about the wheels on the suitcase, Nina?
0:04:38 > 0:04:43Oh, yes, I could roll it, instead of pushing it. Let me try that.
0:04:45 > 0:04:47Oh. Oh, that's much easier.
0:04:47 > 0:04:49And it's just given me an idea
0:04:49 > 0:04:52to show you how bags are moved at an airport.
0:04:52 > 0:04:55Can I ask you to lie down, please?
0:04:55 > 0:04:58There you go.
0:04:59 > 0:05:02And can I ask you to hold this?
0:05:02 > 0:05:04SHE LAUGHS
0:05:04 > 0:05:07- OLLIE:- I hope that isn't heavy. - Don't worry.
0:05:07 > 0:05:09The block is made of light foam.
0:05:09 > 0:05:12But it's true, you should never lie under heavy things.
0:05:12 > 0:05:15OK, guys, I want you to roll this way
0:05:15 > 0:05:18and we'll see what happens to the block of foam.
0:05:18 > 0:05:21Ready, steady, roll!
0:05:22 > 0:05:23Go, go!
0:05:23 > 0:05:26NINA LAUGHS
0:05:26 > 0:05:30Well done, guys! You can stop there. Up you get.
0:05:30 > 0:05:33That was great, and the block of foam moved with you.
0:05:33 > 0:05:36That's because you were moving like a conveyor.
0:05:36 > 0:05:40A conveyor makes it easier to move heavy things.
0:05:40 > 0:05:44And I've got one over here, which I'll show you. Follow me.
0:05:45 > 0:05:49It's like lots of wheels all next to each other.
0:05:49 > 0:05:53So can I ask you to push my suitcase along the conveyor?
0:05:53 > 0:05:55Keep an eye on the rollers.
0:05:56 > 0:05:59- FELIX:- They hardly need to push it, Nina.- I know.
0:05:59 > 0:06:02So what did you notice about the rollers?
0:06:02 > 0:06:06- They all go the same way, Nina. - That's right.
0:06:06 > 0:06:10The rollers all move the same way, just like you all moved the same way
0:06:10 > 0:06:13when you were rolling under the block of foam.
0:06:13 > 0:06:17So can I ask you to push this suitcase along the conveyor again,
0:06:17 > 0:06:21but this time just push it halfway and then let go?
0:06:23 > 0:06:27- It's stopped, Nina. - That's right, it did stop.
0:06:27 > 0:06:30It only moves when you pull or push it.
0:06:30 > 0:06:34So we've discovered that wheels make it easier to move heavy things
0:06:34 > 0:06:39like my suitcase and so does a machine called a conveyor.
0:06:39 > 0:06:42Engineers needed to work out how to move heavy suitcases
0:06:42 > 0:06:46without having to push every one along the conveyor.
0:06:46 > 0:06:50So let's roll along to a place where we can see lots of bags
0:06:50 > 0:06:51to find out more.
0:06:56 > 0:06:59Hmm. Where do you think we're going today?
0:06:59 > 0:07:04- BUD:- Nina said it was somewhere with lots of bags.
0:07:04 > 0:07:08Maybe we're going shopping. I love sniffing out a bargain.
0:07:08 > 0:07:11- FELIX:- We'll soon find out. We've arrived!
0:07:11 > 0:07:15- So, Engineers, where do you think we are?- The airport, Nina.
0:07:15 > 0:07:18Right. People come here to get on aeroplanes
0:07:18 > 0:07:20so they can fly away on holiday.
0:07:20 > 0:07:24LUKE: I can see lots of people with heavy suitcases, Nina.
0:07:24 > 0:07:28- I wouldn't like to lift all these bags.- No, that would be hard work.
0:07:28 > 0:07:30With so many bags here,
0:07:30 > 0:07:34the airport needs machines like conveyors to keep them moving.
0:07:34 > 0:07:36- Can I check this bag in, please?- Yes.
0:07:36 > 0:07:38Oh, thank you.
0:07:44 > 0:07:48We've got permission to follow my suitcase through the airport.
0:07:48 > 0:07:49So let's go.
0:07:53 > 0:07:54Here's my suitcase!
0:07:54 > 0:07:58- Now, did you notice anything about it?- It's moving on its own.
0:07:58 > 0:08:01That's right. Nobody is pushing it.
0:08:01 > 0:08:05This conveyor can move lots of heavy bags and suitcases all at once.
0:08:05 > 0:08:07Let me show you how it works.
0:08:09 > 0:08:12So, a conveyor has rollers inside it
0:08:12 > 0:08:15with a belt that goes around the rollers.
0:08:17 > 0:08:20Motors turn the rollers around, which moves the belt.
0:08:20 > 0:08:26Oh, this actually reminds me of another experiment, so let's go.
0:08:26 > 0:08:28This is a pretend conveyor.
0:08:28 > 0:08:34Now, Maisie and Joe, you are going to turn the rollers towards me,
0:08:34 > 0:08:37and, Lewis, you're going to put the boxes onto the belt.
0:08:37 > 0:08:40So, three, two, one, go!
0:08:42 > 0:08:44Oh, very good.
0:08:44 > 0:08:48BELLE: It's working, Nina! Just like the real conveyor.
0:08:50 > 0:08:54OK, guys, stop, everyone. OK, let's do it one more time.
0:08:54 > 0:08:59Joe, have your hands by your side and don't touch the handle.
0:08:59 > 0:09:03Maisie, can you turn the handle on the roller towards me? Go.
0:09:06 > 0:09:08Keep going.
0:09:08 > 0:09:10LUKE: It's still working, Nina.
0:09:10 > 0:09:14Right. Instead of turning all the rollers in a conveyor,
0:09:14 > 0:09:17only one needs to turn to make the belt move.
0:09:17 > 0:09:20So we've learnt that a conveyor moves heavy things
0:09:20 > 0:09:24without anyone pushing them, even if only one roller is turning.
0:09:24 > 0:09:28Now we know how our suitcases move around the airport,
0:09:28 > 0:09:32but we don't know how they get onto the right plane. Let's find out.
0:09:32 > 0:09:36This is where the airport sorts all the suitcases
0:09:36 > 0:09:40and the slides take the suitcases to the right planes.
0:09:40 > 0:09:42LUKE: Those red lights point at the conveyor.
0:09:42 > 0:09:45Maybe they're party lights!
0:09:45 > 0:09:48Uh-uh! Uh! Uh-uh! Uh! Uh-uh-uh!
0:09:48 > 0:09:51Sorry, Bud, they're not party lights.
0:09:53 > 0:09:57- There's your suitcase, Nina. - So it is.
0:09:57 > 0:10:00I'd best get it before it goes on a plane.
0:10:02 > 0:10:05- OLLIE:- Nina, your suitcase has a label on it.
0:10:05 > 0:10:10Yes, Ollie. That's how the conveyor knows where to send the suitcases.
0:10:10 > 0:10:13Every single suitcase gets one of those labels put on it.
0:10:13 > 0:10:19Now, you might have seen labels like these on other things, like...
0:10:19 > 0:10:20Oh, cereal bars.
0:10:20 > 0:10:24There are red lights in supermarkets that read this
0:10:24 > 0:10:26and tell how much it costs.
0:10:26 > 0:10:29The red lights here at the airport do the same,
0:10:29 > 0:10:33but they tell the conveyor which way to send the suitcase.
0:10:33 > 0:10:36The red light is like the conveyor's eyes?
0:10:36 > 0:10:40Yes. Watching the conveyor has given me an idea for a final experiment.
0:10:40 > 0:10:42So let's go, Engineers.
0:10:44 > 0:10:47We are going to play a sorting game.
0:10:47 > 0:10:50These boxes are the suitcases and they have labels on
0:10:50 > 0:10:53to tell us which plane they need to go on.
0:10:53 > 0:10:57Some have sunshine labels and they need it go on that plane -
0:10:57 > 0:10:59they're off on a beach holiday. Lovely.
0:10:59 > 0:11:03Some have snowflake labels and they need to go on that plane -
0:11:03 > 0:11:06they're off on a snowy holiday, to somewhere cold.
0:11:06 > 0:11:09You guys are like the red lights that read the labels.
0:11:09 > 0:11:12You need to send the suitcases down the right slides
0:11:12 > 0:11:15to the right planes. So are you ready?
0:11:15 > 0:11:18- ALL: Yes!- OK. Let's go.
0:11:46 > 0:11:50Come round, guys. You were great at sorting the suitcases. Well done!
0:11:50 > 0:11:51ALL: Yeah!
0:11:53 > 0:11:54Your question was,
0:11:54 > 0:11:58how do our suitcases get onto the right plane at the airport?
0:11:58 > 0:12:00I think we've answered it.
0:12:00 > 0:12:03A machine called a conveyor can help move things,
0:12:03 > 0:12:05without anyone pushing them,
0:12:05 > 0:12:08thanks to a big belt that's stretched across its rollers.
0:12:08 > 0:12:11We discovered that labels on suitcases
0:12:11 > 0:12:15tell conveyors where to send them to get onto the right plane.
0:12:15 > 0:12:19- So I hope that's answered your question.- ALL: Thanks, Nina.
0:12:19 > 0:12:20You're welcome.
