0:01:05 > 0:01:07# Oh, yeah! #
0:01:08 > 0:01:10- ALL: Hello! - Hello, everyone!
0:01:10 > 0:01:14Do you know, I'm really hungry today and it's ages until lunchtime.
0:01:14 > 0:01:17So I've decided to make myself a snack
0:01:17 > 0:01:20and it's going to be my favourite.
0:01:20 > 0:01:22Can you guess what it is?
0:01:22 > 0:01:26Corn. That's right. I'm going to make popcorn.
0:01:26 > 0:01:28I love popcorn for two reasons -
0:01:28 > 0:01:31one because of its fantastic taste
0:01:31 > 0:01:35and because you use all your senses when you make it.
0:01:35 > 0:01:38Have you ever seen popcorn before it's cooked?
0:01:38 > 0:01:40Look at this.
0:01:40 > 0:01:45They're really small round balls and they feel hard to the touch.
0:01:45 > 0:01:48Now let's get some into the machine.
0:01:48 > 0:01:51That should be plenty.
0:01:52 > 0:01:56In like that. Time to turn the machine on.
0:01:56 > 0:01:58MACHINE WHIRRS
0:01:58 > 0:02:01Now this is my favourite bit.
0:02:01 > 0:02:05Listen really carefully cos we'll start to hear something soon.
0:02:06 > 0:02:09NINA LAUGHS
0:02:09 > 0:02:13The popping sound always makes me laugh.
0:02:14 > 0:02:17If you look really closely you can see
0:02:17 > 0:02:22the small balls of corn turning into the fluffy popcorn.
0:02:22 > 0:02:26The smell's coming out as well. It reminds me of the the cinema.
0:02:26 > 0:02:27MACHINE STOPS
0:02:27 > 0:02:29I think it's ready.
0:02:29 > 0:02:32What a great workout for all five senses.
0:02:32 > 0:02:36I started with touching the corn before it went into the machine.
0:02:36 > 0:02:39Then I heard it popping as it cooked.
0:02:39 > 0:02:45Then I could see the small round balls change into fluffy popcorn.
0:02:45 > 0:02:49Then we could smell the fabulous aroma of it cooking
0:02:49 > 0:02:52and finally, we get to use our sense of taste
0:02:52 > 0:02:54when we enjoy eating it.
0:02:54 > 0:02:56Mmm.
0:02:56 > 0:03:00- APPLAUSE - Aw! Thank you. Thank you for coming
0:03:00 > 0:03:03and I'll see you all again soon. Bye!
0:03:03 > 0:03:04ALL: Bye.
0:03:04 > 0:03:06BEEPING
0:03:06 > 0:03:11Oh, I hear a beep, I see a flash I wonder what they're going to ask.
0:03:13 > 0:03:16KEYPAD BEEPS
0:03:16 > 0:03:18- Hi, Nina.- Hi, Nina.
0:03:18 > 0:03:20Hello. What's your question?
0:03:20 > 0:03:22John wants to know...
0:03:22 > 0:03:27..why does Uncle Bobby put so much salt in his soup?
0:03:27 > 0:03:29Great question, John. You want to know
0:03:29 > 0:03:34why your Uncle Bobby puts so much salt in his soup. I'll find out.
0:03:34 > 0:03:36- Bye! See you soon.- Bye! See you soon.
0:03:36 > 0:03:39I think we'll need help to answer this.
0:03:39 > 0:03:41And I know just who to ask.
0:03:41 > 0:03:44OK, Neurons, time to get to work.
0:03:59 > 0:04:01ALL: Neurons at the ready, Nina!
0:04:02 > 0:04:07Today's question is - why does Uncle Bobby put so much salt in his soup?
0:04:07 > 0:04:10Which Neuron can help us find the answer?
0:04:10 > 0:04:14- ALL: Me! Me! Me! Me! Me! - Me!
0:04:14 > 0:04:16Will it be fabulous Felix?
0:04:16 > 0:04:20I can help so very much if you need the sense of touch.
0:04:20 > 0:04:22Will it be beautiful Belle?
0:04:22 > 0:04:24I send messages brain to ear.
0:04:24 > 0:04:27If there's a sound, I'll help you hear.
0:04:27 > 0:04:29Will it be lovely Luke?
0:04:29 > 0:04:31Looking and seeing, day or night,
0:04:31 > 0:04:34I'll help you with your sense of sight.
0:04:34 > 0:04:35Will it be awesome Ollie?
0:04:35 > 0:04:38If it's pongy or whiffy or you can't tell,
0:04:38 > 0:04:41my messages help your sense of smell.
0:04:41 > 0:04:42Or Baby Bud?
0:04:42 > 0:04:44Sour, salty, bitter or sweet,
0:04:44 > 0:04:47I'm your taste buddy whenever you eat.
0:04:47 > 0:04:50BEEPING
0:04:50 > 0:04:54- It's Bud!- Yippee! - CHEERING
0:04:55 > 0:04:56ALL: Go, Bud! Go, Bud!
0:04:56 > 0:05:00Go, Bud! Go, Bud! Go, Bud!
0:05:00 > 0:05:01Go, Bud!
0:05:01 > 0:05:05- Go, Bud! - Give me a taste of the action, Nina!
0:05:05 > 0:05:09We're gonna investigate our tongues with taste experiments.
0:05:09 > 0:05:12I think Bud is the perfect Neuron to help out.
0:05:15 > 0:05:16OK, then.
0:05:17 > 0:05:19Let's go!
0:05:26 > 0:05:30Mmm? Let's start at the beginning.
0:05:30 > 0:05:31Let me think...
0:05:34 > 0:05:37Oh! That's it. We can start with our tongues!
0:05:37 > 0:05:40- Hi, guys! - ALL: Hi, Nina!
0:05:40 > 0:05:44I'm helping John and Sarah answer their question -
0:05:44 > 0:05:47why does Uncle Bobby use so much salt in his soup?
0:05:47 > 0:05:51Would you like to help us out today?
0:05:51 > 0:05:55- ALL: Yes! - Brilliant. Well, follow me!
0:06:01 > 0:06:05We're going to have a proper look at our tongues -
0:06:05 > 0:06:08so stick your tongue out!
0:06:08 > 0:06:13- Now tell me what you see. - It's got white dots on it.
0:06:13 > 0:06:16- Is it rough or is it bumpy?- Bumpy.
0:06:16 > 0:06:19- What's underneath like? - Smooth!- Smooth!
0:06:19 > 0:06:23Oh, yes, the top is bumpy but underneath feels very different -
0:06:23 > 0:06:25it's all smooth.
0:06:25 > 0:06:29- Does anyone know why our tongues have those bumps?- I don't know.
0:06:29 > 0:06:35- Your taste buds live there. What are your taste buds for?- Tasting.- Yes!
0:06:35 > 0:06:38And taste buds aren't just on our tongues.
0:06:38 > 0:06:42You can also find them in your throat and inside your cheek.
0:06:42 > 0:06:47- So who would like to play a game? - ALL: Yes!
0:06:47 > 0:06:49We're going to play a guessing game.
0:06:49 > 0:06:54Here we have three different size jars of peas.
0:06:54 > 0:06:59I want you to use your imagination and think they're taste buds.
0:06:59 > 0:07:02The small jar has 100 taste buds in it.
0:07:02 > 0:07:06The medium-size jar has 1,000 taste buds in it.
0:07:06 > 0:07:10And the big jar has 10,000 taste buds in it.
0:07:10 > 0:07:13If you have a look around the room,
0:07:13 > 0:07:16you can see they're are pictures of the jars.
0:07:16 > 0:07:20If you think the answer is 100 - run to the small jar.
0:07:20 > 0:07:24If you think the answer is 1,000 - run to the medium-size jar.
0:07:24 > 0:07:30If you think the answer is 10,000 - run to the picture of the big jar.
0:07:30 > 0:07:34And the question - how many taste buds are we born with?
0:07:34 > 0:07:35Three, two , one, go!
0:07:37 > 0:07:43- Oh, so would you like me to tell you who the winners are?- Yes, yes, yes!
0:07:43 > 0:07:50Nobody won because the answer is 10,000 taste buds.
0:07:50 > 0:07:53But, guys, I still don't know why Uncle Bobby
0:07:53 > 0:07:56puts so much salt into his soup.
0:07:56 > 0:07:59I think it's time for me to meet Uncle Bobby.
0:08:04 > 0:08:05In the town of Paisley
0:08:05 > 0:08:09lives John, his sister Sarah, Uncle, Dad and Mum.
0:08:09 > 0:08:13Today for one day only they are...
0:08:15 > 0:08:19..The Experimenters!
0:08:22 > 0:08:25- Hi, everyone! - ALL: Hi!
0:08:25 > 0:08:28- Hello there, John!- Hello!
0:08:28 > 0:08:32So you want to know why Uncle Bobby uses so much salt in his soup?
0:08:32 > 0:08:36I'm here to do some experiments to find the answer.
0:08:36 > 0:08:38Bud is waiting to help us as well.
0:08:38 > 0:08:42BEEPING
0:08:42 > 0:08:43Ready, Bud?
0:08:43 > 0:08:47It's my big moment! Standing by!
0:08:47 > 0:08:49Ready to send lots of messages.
0:08:51 > 0:08:55So for this experiment it's a tasty time of testing our taste buds.
0:08:55 > 0:09:00That's a tongue twister, isn't it? Try saying that quickly.
0:09:00 > 0:09:04Tasty time testing our taste buds! Testy time tasting...
0:09:04 > 0:09:07THEY LAUGH Oh, what a tongue twister!
0:09:07 > 0:09:10We've got four drinks in front of us.
0:09:10 > 0:09:12I'd like you all to have a sip.
0:09:14 > 0:09:16Would John like a taste?
0:09:16 > 0:09:19- Well?- Water.- Water.- Just water.
0:09:19 > 0:09:22OK, now can you all close your eyes.
0:09:22 > 0:09:26Nina wants them to ONLY use their taste buds.
0:09:26 > 0:09:29If they can see they may use their eyes as well
0:09:29 > 0:09:31and that'd ruin the experiment.
0:09:35 > 0:09:38OK, everyone! You can have a taste of your water again.
0:09:40 > 0:09:44- Tell us what you taste now. - Oh, that's water.
0:09:44 > 0:09:45- Sarah?- It's orange.
0:09:45 > 0:09:47- Dad?- Water.
0:09:47 > 0:09:49- Uncle Bobby?- That's water.
0:09:49 > 0:09:54Still water. OK, if you can close your eyes again for me, please.
0:09:54 > 0:09:55SQUIRT!
0:09:55 > 0:09:59Once again, open your eyes and have a drink.
0:09:59 > 0:10:02- Mum, what does that taste of now? - Orange juice?
0:10:02 > 0:10:05- There's a tang of orange juice. - Orange juice?
0:10:05 > 0:10:08- Uncle Bobby, what can you taste? - Still water.
0:10:08 > 0:10:14Everyone has tasted the orange juice in the water except Uncle Bobby.
0:10:14 > 0:10:17Why don't we all close our eyes again?
0:10:21 > 0:10:24We'll just taste it one more time.
0:10:24 > 0:10:25BUD LAUGHS
0:10:25 > 0:10:29Nina's playing a trick on Uncle Bobby!
0:10:29 > 0:10:33She's putting loads and loads of orange juice into the water
0:10:33 > 0:10:35to see if he can taste it now.
0:10:35 > 0:10:37Open your eyes and taste.
0:10:40 > 0:10:44- Uncle Bobby, what can you taste now? - I can taste...orange.
0:10:44 > 0:10:48NEURONS: Hooray! He can taste it! He can taste it!
0:10:48 > 0:10:50Finally, Uncle Bobby could taste it.
0:10:50 > 0:10:55You guys tasted the orange juice with only a little in the water
0:10:55 > 0:10:58but it took more for Uncle Bobby to taste it.
0:10:58 > 0:11:02Remember I told you we're born with 10,000 taste buds,
0:11:02 > 0:11:05well as we get older we start to lose them.
0:11:05 > 0:11:11So Uncle Bobby may only have half the amount of taste buds Sarah does.
0:11:11 > 0:11:16The question - why does Uncle Bobby put so much salt in his soup?
0:11:16 > 0:11:21Mmm? I think we know the answer. We'll find out for sure at lunch.
0:11:25 > 0:11:28Ah! Wow! A picnic!
0:11:28 > 0:11:30What a great idea, Nina!
0:11:30 > 0:11:33Ah, isn't this a perfect place for a picnic?
0:11:33 > 0:11:36Em...what are you doing, Uncle Bobby?
0:11:36 > 0:11:39Why's Nina saying that to Uncle Bobby?
0:11:39 > 0:11:42Uncle Bobby's going to put salt in his soup -
0:11:42 > 0:11:44too much salt's not good for you.
0:11:44 > 0:11:47No, no, salt's not very good for you.
0:11:47 > 0:11:50We need to find other things to make our food tasty.
0:11:50 > 0:11:54You could try some orange juice. Pop some in.
0:11:54 > 0:11:56Have a taste of that.
0:11:56 > 0:11:59Mmm. Mmm. That's nice.
0:11:59 > 0:12:03There's loads of other things you can use instead of salt.
0:12:03 > 0:12:08We've discovered that it's our taste buds that help us taste things.
0:12:08 > 0:12:13We're born with 10,000 of them so we can taste loads of different things.
0:12:13 > 0:12:16But as we grow older, like Uncle Bobby here,
0:12:16 > 0:12:19we start to lose some of them.
0:12:19 > 0:12:23He can't taste his soup as well cos he doesn't have as many taste buds.
0:12:23 > 0:12:27That's why he puts salt in his soup, so he can taste it better.
0:12:27 > 0:12:33Oh, I'd better get back. I've had such a lovely day. Thanks very much!
0:12:33 > 0:12:37- Have a lovely picnic. Bye! - ALL: Bye, Nina!
0:12:37 > 0:12:38Bye!
0:12:50 > 0:12:53# It's been a busy, busy day
0:12:53 > 0:12:56# Questions, answers Experiments done
0:12:56 > 0:12:59# We've all used our senses in so many ways
0:12:59 > 0:13:02# Tell me, Neurons What have you done today? #
0:13:02 > 0:13:06Well, I definitely worked the hardest today.
0:13:06 > 0:13:10Nina showed Uncle Bobby how he can use orange juice instead of salt
0:13:10 > 0:13:12to make his soup lovely and tasty.
0:13:12 > 0:13:15Yeah, I was pretty busy.
0:13:15 > 0:13:20There was lots of looking at those tongues and looking at those peas.
0:13:20 > 0:13:22I was working hard too you know.
0:13:22 > 0:13:27Those tongues felt rough on top and smooth underneath.
0:13:27 > 0:13:29There were sounds to keep me busy.
0:13:29 > 0:13:33There was lots of listening at questions and answers.
0:13:33 > 0:13:37The orange juice made a funny skooshing noise when she put it in.
0:13:37 > 0:13:42I was busy helping my little brother cos there was tasting to be done.
0:13:50 > 0:13:56That was great fun. I hope you've had a sensational time too. Bye!
0:13:56 > 0:13:58ALL: Bye!
