0:00:57 > 0:00:58SHE HUMS
0:01:01 > 0:01:06Oh, hello. I'm just tidying up after making these lovely biscuits.
0:01:06 > 0:01:07BEEPING
0:01:07 > 0:01:11I hear a peep, I see a flash, I wonder what they're going to ask?
0:01:11 > 0:01:13BEEPING
0:01:16 > 0:01:22- Hi, Nina.- Hi, guys. - We've got a question for you.
0:01:22 > 0:01:25How are biscuits in a packet made all the same?
0:01:25 > 0:01:27That's a great question.
0:01:27 > 0:01:30How are biscuits in a packet made all the same?
0:01:30 > 0:01:34When we buy biscuits from the shops, they're all the same,
0:01:34 > 0:01:39and they taste yummy too. Come down and we'll investigate.
0:01:39 > 0:01:43- See you soon, Nina, bye!- Bye!
0:01:43 > 0:01:47I'll need help to answer this and I know just who to ask.
0:01:47 > 0:01:50OK, Neurons, time to get to work.
0:02:05 > 0:02:08ALL: Neurons at the ready, Nina.
0:02:08 > 0:02:12So, how are biscuits in a packet made all the same?
0:02:12 > 0:02:16Which Neuron will be most useful to help find the answer?
0:02:16 > 0:02:19ALL: Me! Me! Me! Oh, me!
0:02:19 > 0:02:22Will it be fabulous Felix?
0:02:22 > 0:02:26I can help so very much if you need the sense of touch.
0:02:26 > 0:02:28Will it be beautiful Belle?
0:02:28 > 0:02:33I send messages to brain from ear. If there's a sound, I'll help you hear.
0:02:33 > 0:02:34Will it be lovely Luke?
0:02:34 > 0:02:37For looking and seeing, day or night,
0:02:37 > 0:02:39I'll help you with your sense of sight.
0:02:39 > 0:02:41Will it be awesome Ollie?
0:02:41 > 0:02:44If it's pongy or whiffy but you can't tell,
0:02:44 > 0:02:48- my messages help your sense of smell. - Or will it be baby Bud?
0:02:48 > 0:02:53Sour, salty, bitter or sweet, I'm your taste buddy whenever you eat!
0:02:55 > 0:03:00- It's Bud! - CHEERING
0:03:00 > 0:03:06ALL CHANT: Go, Bud! Go, Bud! Go, Bud! Go, Bud! Go, Bud! Go, Bud!
0:03:06 > 0:03:10Hooray! Bring on the tasting, Nina!
0:03:10 > 0:03:11Today's question is,
0:03:11 > 0:03:14how are biscuits in a packet made all the same?
0:03:14 > 0:03:18Biscuits are something we taste, so Bud will be helping us.
0:03:18 > 0:03:21But, Neurons, I may need help from all of you.
0:03:21 > 0:03:27I need to get the workshop ready before the engineers arrive.
0:03:27 > 0:03:32Faaizah likes ice cream. Farhan loves playing on the slide.
0:03:32 > 0:03:34Biscuits in a packet look the same.
0:03:34 > 0:03:37Home-made biscuits are different shapes.
0:03:37 > 0:03:40Today, for one day only, they are the engineers.
0:03:44 > 0:03:48- Hi, guys! - BOTH: Hi, Nina!
0:03:48 > 0:03:51Welcome, and thanks for your great question.
0:03:51 > 0:03:54How are biscuits in the packet made all the same?
0:03:54 > 0:03:58To find out, we're going to start by using our senses.
0:03:58 > 0:04:02ALL: Whoop! Woo! A senses experiment! We're ready, Nina!
0:04:02 > 0:04:07We can't have a question about biscuits without tasting some.
0:04:07 > 0:04:11I just happen to have made some biscuits today. Shall we try one?
0:04:11 > 0:04:14Are they meant to be different shapes and sizes, Nina?
0:04:14 > 0:04:17Actually, they were meant to be circles.
0:04:17 > 0:04:21They look a bit wonky, don't they? There we go.
0:04:22 > 0:04:23Lovely.
0:04:25 > 0:04:26Mmm...
0:04:26 > 0:04:29They might look funny, but they are yummy.
0:04:29 > 0:04:34They all taste good, and they feel and smell the same.
0:04:34 > 0:04:39But they look a bit different to these biscuits from shop.
0:04:39 > 0:04:41Even the patterns on them match.
0:04:41 > 0:04:45I wonder if we could make biscuits a bit more like that?
0:04:45 > 0:04:47Let us wash our hands and have a go.
0:04:57 > 0:05:00This is biscuit dough.
0:05:00 > 0:05:03We are going to make circles of exactly the same size
0:05:03 > 0:05:05using these cutters.
0:05:09 > 0:05:11Woo!
0:05:16 > 0:05:21Oh, this is taking ages! When is it time to eat them?
0:05:21 > 0:05:25I don't think it's a good idea to eat dough before it's cooked, Bud.
0:05:25 > 0:05:31Cutters down, guys. Now, we can try and make the same pattern.
0:05:31 > 0:05:36I think I'll try and make a big N for "Nina"!
0:05:36 > 0:05:39OK, let's see how this works.
0:05:39 > 0:05:42Oh, I'll try another one.
0:05:47 > 0:05:52- They are not exactly the same, are they?- No, Nina.- No.
0:05:52 > 0:05:55The cutters made the same shape,
0:05:55 > 0:05:58but it's difficult getting the patterns the same.
0:05:58 > 0:06:02We need something to make this easier, maybe these will help.
0:06:02 > 0:06:04There you go.
0:06:05 > 0:06:10These are biscuit stamps. I'll show you how they work.
0:06:10 > 0:06:16You press them onto the biscuit dough and they make a pattern.
0:06:16 > 0:06:21Oh, look, a lion! I like lions especially when they ro-o-oar!
0:06:21 > 0:06:24ALL GASP Sorry.
0:06:31 > 0:06:34Oh, we've finished! Have a look!
0:06:34 > 0:06:38The cutters and the stamps have made them all the same.
0:06:38 > 0:06:41We found out that by using a cutter and a stamp,
0:06:41 > 0:06:45we can make everything exactly the same shape and pattern.
0:06:45 > 0:06:48It's quicker and easier than using our hands.
0:06:48 > 0:06:52But, we have only made a few biscuits.
0:06:52 > 0:06:55There are hundreds of biscuits in the shops,
0:06:55 > 0:06:59so how have engineers solved the problem of making a lot of biscuits
0:06:59 > 0:07:01in the same shape quickly?
0:07:01 > 0:07:04I think we need to go somewhere noisy to find out.
0:07:09 > 0:07:13- Oh, I wonder where we're going today? - Nina said it was somewhere noisy.
0:07:13 > 0:07:18- Not too noisy, I hope. - I hope there are lots of noises.
0:07:18 > 0:07:22- I like being kept busy. - Well, we're about to find out.
0:07:22 > 0:07:25- Do you know where we are? - In the biscuit factory!
0:07:25 > 0:07:28Yes, this is a biscuit factory,
0:07:28 > 0:07:32that's why we have to wear these special clothes and these hairnets.
0:07:32 > 0:07:35The hairnets make sure that no hairs get into biscuits.
0:07:35 > 0:07:39Oh, when do we get to taste the biscuits, Nina?
0:07:39 > 0:07:42Bud, we're not here to taste the biscuits,
0:07:42 > 0:07:46we are here to find out how these biscuits are made using machines.
0:07:46 > 0:07:48So, let see.
0:07:51 > 0:07:55What a lot of biscuits! I've never seen so many!
0:07:55 > 0:07:59This machine is cutting the biscuits into exactly the same shape,
0:07:59 > 0:08:02and stamping the same pattern on them,
0:08:02 > 0:08:05just like we did with our cutters and stamps.
0:08:05 > 0:08:08- It's much faster, isn't it?- Yes!
0:08:08 > 0:08:11Now, the biscuits will go into an oven to be baked.
0:08:13 > 0:08:17Oh, they look so yummy, but they are still not finished.
0:08:17 > 0:08:20- What else do they need? - The middle.- That's right!
0:08:20 > 0:08:23And this is done by another machine.
0:08:26 > 0:08:30Do you see how the machine lines up the biscuits,
0:08:30 > 0:08:33and adds the middle in exactly the same way?
0:08:33 > 0:08:37The tops go on there and our biscuits are finished!
0:08:37 > 0:08:40So, to make biscuits quickly and all the same,
0:08:40 > 0:08:43engineers have made machines to do it.
0:08:43 > 0:08:47Each machine has its own job to do to help make the biscuit.
0:08:47 > 0:08:49This is called a production line.
0:08:49 > 0:08:53- A what?- A production line, Bud.
0:08:53 > 0:08:58- Really, should listen more. - That's your job! Hahaha!
0:08:58 > 0:09:02Each machine in the factory is in a line.
0:09:02 > 0:09:05They all do their own job over and over again.
0:09:05 > 0:09:09The biscuit goes along the line, and each machine adds something.
0:09:09 > 0:09:14Why can't one machine do everything? Let's do an experiment find out.
0:09:17 > 0:09:21So, how are biscuits in a packet made all the same?
0:09:21 > 0:09:25We found out that factories use a production line of machines,
0:09:25 > 0:09:29that each do a different job, and we're going to find how that works.
0:09:29 > 0:09:32I've got a box here,
0:09:32 > 0:09:35and I'd like you guys to make one exactly the same,
0:09:35 > 0:09:38using the things in front of you.
0:09:38 > 0:09:40Try and make it quickly,
0:09:40 > 0:09:43and finish your box before I pass you the next one.
0:09:43 > 0:09:45- OK?- Yes, Nina.
0:09:45 > 0:09:48Three, two, one, go!
0:10:06 > 0:10:09The boxes are coming too fast. They can't keep up.
0:10:17 > 0:10:23- OK, stop there! Oh, that was hard, and it took a long time.- Yes, Nina.
0:10:23 > 0:10:25Let's try it a different way.
0:10:25 > 0:10:29This time, we're going to make our very own production line,
0:10:29 > 0:10:31doing one job each.
0:10:31 > 0:10:33I'll put on the strawberry sticker,
0:10:33 > 0:10:36Farhan can stick on the blue rectangle,
0:10:36 > 0:10:38and Faaizah, you do the red circle.
0:10:38 > 0:10:44- OK, ready?- Yes, Nina. - Three, two, one, go!
0:10:55 > 0:10:57Oooh!
0:11:05 > 0:11:07You're doing brilliantly, guys!
0:11:14 > 0:11:19Well done, we've made some lovely boxes on our production line!
0:11:19 > 0:11:23- Was it easier with just one job to do?- Yes, Nina!
0:11:23 > 0:11:26Building a machine that does everything is difficult,
0:11:26 > 0:11:30especially if you're making something with many parts.
0:11:30 > 0:11:35Engineers solve this problem by making lots of machines in a line.
0:11:35 > 0:11:38Lots of things are made in production lines like cars,
0:11:38 > 0:11:40televisions and computers.
0:11:40 > 0:11:45# Nina and the Neurons! #
0:11:45 > 0:11:49Your question was, how are biscuits in a packet made all the same?
0:11:49 > 0:11:51I think we have answered it.
0:11:51 > 0:11:54Engineers made machines that use cutters and stamps
0:11:54 > 0:11:57to quickly make the same shape over and over again.
0:11:57 > 0:12:02A production line is a line of machines doing different jobs.
0:12:02 > 0:12:05Machines on a production line make things the same,
0:12:05 > 0:12:09and much quicker than we could. I hope that answers your question.
0:12:09 > 0:12:14- Thanks, Nina, bye! - You're welcome, bye.

0:13:29 > 0:13:33There were biscuits here, there, and everywhere!
0:13:33 > 0:13:36Yummy!
0:13:36 > 0:13:39I really enjoyed myself today.
0:13:39 > 0:13:43Nina's biscuits may have looked funny, but they smelled delicious.
0:13:43 > 0:13:45I've had a brilliant day!
0:13:45 > 0:13:47Who would have thought
0:13:47 > 0:13:51biscuit-making machines would have been so noisy!
0:13:51 > 0:13:54Engineers help to build the world around us.
