0:00:05 > 0:00:08# If you've got a question and you don't know where to go
0:00:08 > 0:00:11# Ask Nina for some help, cos she's got a science show
0:00:11 > 0:00:14# She makes sense of her senses While helping all her fans
0:00:14 > 0:00:17# By doing her experiments with potions and with bangs
0:00:17 > 0:00:19- # Touch your tongue - Tongue!

0:01:02 > 0:01:05# Nina and the Neurons find out what you need to know
0:01:05 > 0:01:07# Oh yeah! #
0:01:08 > 0:01:11- Hi, everyone! - ALL: Hi, Nina!
0:01:11 > 0:01:14Our experiment today is really simple.
0:01:14 > 0:01:16I have two beakers of water.
0:01:16 > 0:01:20What would happen if I put all this water into this dish?
0:01:20 > 0:01:22ALL: It will spill!
0:01:22 > 0:01:26Well, you know what, I'm feeling quite daring today
0:01:26 > 0:01:27so I'm going to try.
0:01:27 > 0:01:31But don't worry, I've got a cloth here in case I make a mess.
0:01:31 > 0:01:32So here we go...
0:01:36 > 0:01:38Look!
0:01:38 > 0:01:41It's not spilling everywhere.
0:01:41 > 0:01:44It's going hard, and turning to ice!
0:01:45 > 0:01:47And look!
0:01:47 > 0:01:49It's getting higher and higher.
0:01:49 > 0:01:53- It's starting to look like an icicle, isn't it?- ALL: Yes.
0:01:53 > 0:01:55So it must be really cold in here.
0:01:55 > 0:01:57Are you guys cold?
0:01:57 > 0:01:58ALL: No.
0:01:58 > 0:02:00No, neither am I.
0:02:00 > 0:02:04And look, it's getting really, really high now.
0:02:04 > 0:02:07I'll let you into a little secret, actually.
0:02:07 > 0:02:10It's not really water. And it's not really ice.
0:02:10 > 0:02:14In fact, it's not even cold. It's quite warm.
0:02:14 > 0:02:19In these beakers is a special chemical called sodium acetate.
0:02:19 > 0:02:23At this temperature, it looks just like water.
0:02:23 > 0:02:26But when it touches something else, like this dish,
0:02:26 > 0:02:28or my stirring rod,
0:02:28 > 0:02:34chemicals inside it react, and it becomes warm and turns solid.
0:02:34 > 0:02:40That's why it didn't spill all over the table. And I didn't make a mess.
0:02:40 > 0:02:42BEEPING
0:02:43 > 0:02:48Oh, I hear a beep, I see a flash, I wonder what they're going to ask.
0:02:50 > 0:02:54Hi, Nina, my name is Hasham and I've got a question for you.
0:02:54 > 0:02:56Where does our rubbish go?
0:02:56 > 0:03:01Oh, that's a brilliant question, Hasham - where does our rubbish go?
0:03:01 > 0:03:04Where does our rubbish go after we throw it out?
0:03:04 > 0:03:09- Thanks, Hasham, I'll be over to see you soon.- See you soon, Nina. Bye.
0:03:11 > 0:03:15I'm going to need help to answer this, and I know just who to ask.
0:03:15 > 0:03:17OK, Neurons, time to get to work.
0:03:32 > 0:03:35ALL: Neurons at the ready, Nina.
0:03:35 > 0:03:39OK. Today's question is, "Where does our rubbish go?"
0:03:39 > 0:03:43Which Neuron will be most useful in finding the answer?
0:03:43 > 0:03:45ALL: Me, me, me!
0:03:46 > 0:03:49Will it be fabulous Felix?
0:03:49 > 0:03:53I can help so very much, if you need the sense of touch.
0:03:53 > 0:03:55Will it be beautiful Belle?
0:03:55 > 0:04:00I send messages to brain from ear, if there's sound, I'll help you hear.
0:04:00 > 0:04:01Will it be lovely Luke?
0:04:01 > 0:04:06For looking, day or night, I'll help you with your sense of sight.
0:04:06 > 0:04:08Will it be awesome Ollie?
0:04:08 > 0:04:11If it's pongy, or whiffy, but you can't tell,
0:04:11 > 0:04:13I can help your sense of smell.
0:04:13 > 0:04:15Or will it be baby Bud?
0:04:15 > 0:04:19Sour, salty, bitter or sweet, I'm your taste buddy when you eat.
0:04:23 > 0:04:24It's Luke!
0:04:24 > 0:04:25Yes!
0:04:25 > 0:04:28ALL: Go Luke, go Luke, go Luke.
0:04:28 > 0:04:32ALL: Go Luke, go Luke, go Luke, go Luke.
0:04:32 > 0:04:34Cool, Nina.
0:04:34 > 0:04:36I'll be looking out to help you.
0:04:36 > 0:04:40Thanks, Luke. Our question is, "Where does our rubbish go?"
0:04:40 > 0:04:44As rubbish is something we see, Luke will help.
0:04:44 > 0:04:48But stand by, Neurons, I might need all of you today.
0:04:48 > 0:04:51OK. Let's go.
0:05:08 > 0:05:11Hasham will find out about rubbish.
0:05:11 > 0:05:15Rotten rubbish, noisy rubbish, even really smelly rubbish.
0:05:15 > 0:05:20So today, for one day only, Hasham and his sister Rania become...
0:05:20 > 0:05:21The Experimenters!
0:05:25 > 0:05:28- Hi, everyone. - BOTH: Hi, Nina!
0:05:28 > 0:05:31I see you're busy putting your rubbish in the bin
0:05:31 > 0:05:34and I can see there's a lot.
0:05:34 > 0:05:38And Hasham, your question is, "Where does our rubbish go?"
0:05:38 > 0:05:43- Why do you ask that?- I was wondering where it goes in the bin lorry.
0:05:43 > 0:05:47To help answer your question, I think we need to take a trip.
0:05:47 > 0:05:49- So, are you ready? - BOTH: Yes!
0:05:49 > 0:05:50Good, let's go.
0:05:58 > 0:06:03Oh, look at this place - there's rubbish lying everywhere!
0:06:03 > 0:06:07Even mouldy food, ew, yuck!
0:06:07 > 0:06:12This is where our rubbish is brought when the bin lorry takes it away.
0:06:12 > 0:06:16This is a landfill site. Normally, people aren't allowed here,
0:06:16 > 0:06:21but we have special permission. Look, the lorries are just arriving.
0:06:21 > 0:06:24I wonder if your rubbish is in there.
0:06:25 > 0:06:30When it arrives, they put it in the ground and cover it with soil.
0:06:30 > 0:06:34If it's in the ground, why is there still so much around?
0:06:34 > 0:06:39Burying rubbish isn't a good way of getting rid of things we don't need.
0:06:39 > 0:06:43It's like trying to tidy your bedroom by putting your smelly socks
0:06:43 > 0:06:47under your bed. Soon there would be so much there,
0:06:47 > 0:06:48there's no more room.
0:06:48 > 0:06:51That's what's happening at landfill sites.
0:06:51 > 0:06:55Because there's so much rubbish, they're filling up,
0:06:55 > 0:06:59- and soon they'll be full. - Where will rubbish go then?
0:06:59 > 0:07:02Perhaps there are other places rubbish could go
0:07:02 > 0:07:06before the landfill sites become too full. I've got an idea!
0:07:08 > 0:07:13OK, we need to find out if there are other places for our rubbish.
0:07:13 > 0:07:14That's why we're here.
0:07:14 > 0:07:16More bins, Nina?!
0:07:16 > 0:07:19Don't worry. These are different.
0:07:19 > 0:07:24These are recycling bins because the rubbish in them can be used again.
0:07:24 > 0:07:28Lots of rubbish that we put into our bins at home can go here instead.
0:07:28 > 0:07:30Like what, Nina?
0:07:30 > 0:07:33Well I've put symbols in front of these bins
0:07:33 > 0:07:37and it tells us what type of rubbish goes in them. Let's work it out.
0:07:37 > 0:07:40- What goes in this bin here? - Plastic.
0:07:40 > 0:07:44That's right. You can put plastic bottles in there.
0:07:44 > 0:07:46- What about in this bin?- Paper.
0:07:46 > 0:07:48Yes, correct, well done.
0:07:48 > 0:07:51And what rubbish do you think we'd put in here?
0:07:51 > 0:07:53- Glass.- That's right.
0:07:53 > 0:07:57Although, we must be careful when handling things made of glass.
0:07:57 > 0:08:02It's important to get the right bit of rubbish in the right bin.
0:08:02 > 0:08:06The symbols on the front will tell them all they need to know.
0:08:06 > 0:08:10I think you're ready to play a little recycling game.
0:08:10 > 0:08:13I brought this to help us - my rubbish!
0:08:13 > 0:08:16Really, Nina? Bringing out your old rubbish?
0:08:16 > 0:08:18That's not very nice.
0:08:18 > 0:08:22Don't worry, Felix, everything's washed so it's clean.
0:08:22 > 0:08:25What I want you to do is pick something from the bag,
0:08:25 > 0:08:30decide what it's made of and put it in the right recycling bin.
0:08:30 > 0:08:32- Ready?- BOTH: OK, Nina!
0:08:32 > 0:08:33That's it, pull it out.
0:08:33 > 0:08:38If you have a good look at rubbish, you can normally tell what it is.
0:08:47 > 0:08:50Good job, Rania. These guys are good at this.
0:08:56 > 0:09:01Listen to the tinkling and smash of the glass as it falls into the bin.
0:09:01 > 0:09:03CLINK!
0:09:03 > 0:09:05Wow, everything's gone.
0:09:05 > 0:09:08All that I've got left is this old paper.
0:09:08 > 0:09:10We've recycled all my rubbish.
0:09:10 > 0:09:12Thanks, guys.
0:09:12 > 0:09:15Lots of things can be recycled.
0:09:15 > 0:09:19and when we recycle rubbish, it doesn't go to the landfill site,
0:09:19 > 0:09:23it goes to recycling factories so it can be used again.
0:09:23 > 0:09:27How can recycling factories turn old rubbish into new things?
0:09:27 > 0:09:28Good question, Hasham.
0:09:28 > 0:09:33I've still got this old paper. That gives me an idea for an experiment.
0:09:35 > 0:09:41So far, we know that the rubbish in our bins goes to the landfill.
0:09:41 > 0:09:44But this isn't a good way to get rid of things.
0:09:44 > 0:09:47A better way is to put it in recycling bins.
0:09:47 > 0:09:51Then it can be collected and used again.
0:09:51 > 0:09:54Now we'll learn how we can recycle rubbish.
0:09:54 > 0:09:56By turning old paper into new paper.
0:09:56 > 0:09:59- Shall we get recycling?- BOTH: Yes!
0:09:59 > 0:10:03Fantastic. The first thing we need to do is rip up some paper.
0:10:03 > 0:10:06So there's some for you, Hasham.
0:10:06 > 0:10:09You need to make it into really small pieces.
0:10:10 > 0:10:14Listen to the lovely tearing sound of the paper. R-r-rip!
0:10:14 > 0:10:18Now we just need enough water to soak all the paper.
0:10:18 > 0:10:19BOTH: Yes.
0:10:19 > 0:10:23Ahh! Perfect.
0:10:23 > 0:10:25Let's get mashing.
0:10:28 > 0:10:32- How's it going, is your paper mushy? - BOTH: Yes.
0:10:32 > 0:10:34It's time for the next step.
0:10:34 > 0:10:38Bring the basin full of water around here.
0:10:40 > 0:10:45Excellent, spread it out. Try not to lose too much paper over the sides.
0:10:45 > 0:10:49Ooh! Let's bring this round here.
0:10:52 > 0:10:54Here we are.
0:10:54 > 0:10:57Right, let's just open this out.
0:10:57 > 0:11:02Take the wooden frame onto the piece of paper.
0:11:02 > 0:11:06Turn over this paper so we can use that to soak it up as well.
0:11:06 > 0:11:10Everyone get your hands in there, squeeze to soak up all the water.
0:11:10 > 0:11:12Good job, guys.
0:11:12 > 0:11:15OK, now let's open this up.
0:11:15 > 0:11:17And we're going to turn it over.
0:11:18 > 0:11:19And now...
0:11:19 > 0:11:23Careful, Nina! You need a steady hand for this job.
0:11:23 > 0:11:26Woohoo! Look at that.
0:11:26 > 0:11:31It's really starting to look like paper. Let's dry our hands.
0:11:31 > 0:11:36Because, to really dry off this paper, we're using a hairdryer.
0:11:36 > 0:11:38Here we are.
0:11:41 > 0:11:44Lift the wet newspaper away.
0:11:45 > 0:11:50Look at that. We have made a brand new sheet of paper.
0:11:50 > 0:11:54We recycled the old paper to make new paper.
0:11:54 > 0:11:57That's like what happens in recycling factories,
0:11:57 > 0:12:01except they have big machines and they make more paper.
0:12:01 > 0:12:03BOTH: Brilliant, Nina.
0:12:03 > 0:12:08Yeah, it is brilliant. And there's other things we can recycle too.
0:12:08 > 0:12:11We can reuse carrier bags that we get when we're shopping,
0:12:11 > 0:12:15and we can use old paper to write and draw on.
0:12:20 > 0:12:24Well, I've had great fun, guys. Recycling rubbish is fun.
0:12:24 > 0:12:28Hasham, you asked, "Where does our rubbish go?" Now you know.
0:12:28 > 0:12:32Rubbish from our bins goes to a landfill site,
0:12:32 > 0:12:34but soon there will be no more room there,
0:12:34 > 0:12:38so we should recycle it. If we put rubbish in recycling bins,
0:12:38 > 0:12:42it gets reused, and less goes to the landfill site.
0:12:42 > 0:12:45Which helps protect our planet.
0:12:45 > 0:12:48- Thanks, Nina. We're going to recycle lots.- Brilliant.
0:12:48 > 0:12:52I'm glad to hear it. Most rubbish can be recycled,
0:12:52 > 0:12:56- so stop and think before you throw anything out.- BOTH: We will, Nina.
0:13:01 > 0:13:03# Help protect our planet
0:13:03 > 0:13:07- # Go eco!- Go eco!
0:13:07 > 0:13:09# Walk to school or cycle
0:13:09 > 0:13:13- # Go eco!- Go eco!
0:13:13 > 0:13:16# Turn off the tap Switch off the light
0:13:16 > 0:13:18# Recycle what you can
0:13:18 > 0:13:21# Help protect our planet
0:13:21 > 0:13:25- # Go eco!- Go eco!
0:13:25 > 0:13:26# Go eco. #
0:13:26 > 0:13:29I really enjoyed myself today.
0:13:29 > 0:13:32The smell of the landfill site was a little bit whiffy.
0:13:32 > 0:13:36Ah, it's been such a great day, man.
0:13:36 > 0:13:39Seeing all the types of rubbish you can recycle.
0:13:39 > 0:13:41Oh, I've had a brilliant day.
0:13:41 > 0:13:47Hearing the clinking and clanking of Nina's rubbish.
0:13:47 > 0:13:49I've had a fabby day.
0:13:49 > 0:13:54I liked it when everyone was mashing up the paper till it went gooey.
0:13:54 > 0:13:56It's been a marvellous day.
0:13:56 > 0:14:01It was interesting seeing how old paper can be turned into new.
0:14:01 > 0:14:06We've had a sensational time. I hope you've enjoyed it too. See you soon!
0:14:06 > 0:14:08ALL: Bye!
