00:06If you've got a question and you don't know where to go, ask Nina for some help, cause she's got
00:11a science show.
00:12She makes sense of her senses while helping all her fans, by doing her experiments with potions and with bags.
00:18Touch her tongue, fingers, eyes, ears, nose.
00:24Every day we use our senses wherever we may go.
00:31Tongue, fingers, eyes, ears, nose.
00:36Nina and the neurons find out what you need to know.
00:39Nina and the neurons find out what you need to know.
00:42Look, he helps us with our eyes and Felix with our touch.
00:45Ollie sticks our skulls and some bells she hears so much.
00:48But it's Ollie's brother, he helps us with our taste.
00:51Then he has little neurons and they're coming to your place.
00:54Touch her tongue, fingers, eyes, ears, nose.
01:00Nina and the neurons find out what you need to know.
01:03Yeah!
01:03Nina and the neurons find out what you need to know.
01:06Oh yeah!
01:08Hi everyone!
01:10Hi Nina!
01:12Now I have got a very exciting experiment to show you today.
01:15I'm going to try and move water from one glass to another without touching any of the glasses.
01:21So what do you think?
01:22Can I do it?
01:23No!
01:24Oh ho ho!
01:25Well it does sound pretty tricky, doesn't it?
01:27Well watch carefully.
01:29First of all, I'm going to pop some green food colouring into the water just so we can see it
01:35better.
01:36Oh great, look at that, a wee stir.
01:39Now what I'm going to do is take this long piece of kitchen paper and sit it over both the
01:45glasses and let's see what happens.
01:48Oh look at that!
01:49The water's soaking into the paper heading towards the other glass.
01:53Oh ho!
01:54But what do you think will happen when the water gets to the edge of the paper?
01:59Do you think it will stop?
02:01Or do you think it will drip?
02:02Drip!
02:04I'm not sure.
02:05We're about to find out.
02:10It's dripping!
02:11Yay, so I did manage to do it.
02:13I managed to move water from one glass to another without touching any of the glasses.
02:17You see, when we put the paper in, the water climbed all the way along the paper into the other
02:23glass.
02:24And now this climbing of the water is called capillary action and it's very, very useful in nature because it's
02:31how trees get water from the ground.
02:37Oh, I hear a beep.
02:39I see a flash.
02:40I wonder what they're going to ask.
02:46Hello, Nina.
02:47My name's Tyler and I've got a question to ask you.
02:50Why do we have slugs in our garden?
02:52Oh, that's a great question, Tyler.
02:54Why do we have slugs in our garden?
02:57I think we're going to have lots of fun finding this out.
02:59Thanks, Tyler.
03:00I'll be over soon.
03:01See you soon, Nina.
03:03Bye.
03:03Bye.
03:05Well, I'm going to need some help to answer this one and I know just who to ask.
03:09Okay, neurons.
03:10Time to get to work.
03:29Okay, today's question is why do we have slugs in our garden?
03:33Now, which neuron do you think will be most useful in helping us find the answer?
03:37Me.
03:38Me.
03:39Me.
03:39Me.
03:40Me.
03:40Me.
03:41Will it be fabulous Felix?
03:43I can help so very much if you need the sense of touch.
03:47Will it be beautiful Belle?
03:49I send messages to Brain from ear.
03:51If there's a sound, I'll help you hear.
03:53Will it be lovely Luke?
03:55For looking and seeing, day or night, I'll help you with your sense of sight.
04:00Will it be awesome Ollie?
04:02If it's Pony or Whiffy, but you can't tell, my messages help your sense of smell.
04:07Or will it be baby bud?
04:09Salty, salty, bitter, or sweet.
04:11I'm your case buddy whenever you eat.
04:18It's Luke.
04:20Go, Luke.
04:21Go, Luke.
04:22Go, Luke.
04:24Go, Luke.
04:25Go, Luke.
04:26Go, Luke.
04:27Go, Luke.
04:31Go, Luke.
04:32Thanks, Luke.
04:32Today's question is why do we have slugs in our garden?
04:36And as slugs are something we see in a garden, Luke will be helping us, but stand by neurons.
04:40I think I'm going to need help from all of you today.
04:44Okay.
04:46Let's go.
04:47Okay.
05:07Tyler will be finding out all about slugs.
05:10Little, tiny, slimy slugs, great, big, hungry slugs, and shiny slugs of all shapes and sizes.
05:17So today, for one day only, Tyler, Dad and Cousin Janae become the experimenters.
05:25Hi, everyone.
05:26Hi, Nina.
05:28Oh, you look busy.
05:29We're buying food out for the birds.
05:31We are going to have loads of birds in the garden today.
05:33And speaking of having things in the garden, Tyler, your question is why do we have slugs
05:39in our garden?
05:40So why do you want to know about slugs?
05:42I don't like slugs because my dad gets in our garden because sometimes they eat as plants.
05:47I think we should find out a bit more about them to try and work out why they're in the
05:51garden.
05:52So are you ready for a slug search?
05:54Yeah!
05:58Okay, Tyler, in order to answer your question, why do we have slugs in our garden, we're
06:02going to try and find out exactly where in the garden the slugs are living.
06:06So are you up for the challenge?
06:08Yes, Nina.
06:09Let's get searching.
06:18Nina, there's a slug over there on that cabbage leaf.
06:22Good work, Tyler.
06:24Let's have a closer look.
06:29It's an enormous slug.
06:31Calm down, Felix, man.
06:33It just looks that way because Nina's using a magnifying glass.
06:38That makes things look much bigger so we can see them better.
06:42Now, so we don't forget where this slug is, let's mark the spot using one of these flags.
06:49Excellent.
06:52There's one, Nina.
06:54Oh, so there is.
06:56Well done, Jeannie.
06:57Let's have a closer look.
06:59Whoa.
07:01Hoo-wee.
07:02Nina, that compost heap is really whiffy.
07:06I agree, Ollie, but a compost heap is a great place for recycling.
07:11You can put lots of garden waste in it, like grass cuttings or even old vegetable peelings.
07:16And over time, it rots away to become compost, which you can then use to put in the garden
07:22to feed the plants.
07:24Oh, but a compost heap can be a bit smelly.
07:27But this slug doesn't seem to mind.
07:29I think he's pretty happy living in it.
07:31So, let's pop a flag in and go and find some more slugs.
07:38Hey, look at that, Nina.
07:40It's a slimy trail.
07:42Something tells me you might find something in there if you look hard enough.
07:46You're right, Luke.
07:48Slugs and snails can sometimes leave a slimy trail behind them.
07:52So, shall we follow it to see where it leads?
07:54Yeah.
07:55OK.
07:59Oh, wow, we've found another one.
08:01Fantastic.
08:02Oh, and he looks really comfy in these old rotting leaves.
08:06So, let's put the last flag in.
08:10Oh, great work, experimenters.
08:13So, let's take a look around to see where we've put all the flags,
08:16and that'll tell us exactly where all the slugs live in the garden.
08:19In the old rotten leaves, in the smelly compost, and on the cabbages.
08:26That's right, and the reason we've found slugs in these places
08:29is because they eat all of these things.
08:32And although slugs eat some things that we don't want them to eat,
08:35like your dad's cabbages,
08:36they also eat things that are really useful that we want to get rid of,
08:39like old leaves and rotten vegetables.
08:43That would taste horrible.
08:45Not to slugs, though, Baud.
08:46That would be like a big fancy dinner to them.
08:49So, through our slug search,
08:51we found out that we have slugs in the garden
08:53because there's lots of things for them to eat.
08:55So, slugs can be very useful.
08:58And there's another reason why slugs are good to have around.
09:01And to explain why, I think we need to play another game.
09:04Yay!
09:07OK, guys, to find out another reason why we have slugs in the garden,
09:11we're going to play a game,
09:12and this game is called the food chain game.
09:15Have you ever heard of a food chain before?
09:17No.
09:18Well, it's all about what animals eat.
09:23Here I have some grain.
09:26And that's what that looks like there.
09:29And I'm going to set this arrow here.
09:32Now, which of these two animals
09:37do you think eats the grain?
09:39The fox or the chicken?
09:41Eh, um, oh, hold on a minute.
09:44I'm sure I know the answer, Nina.
09:47The chicken.
09:48Exactly what I would have said.
09:50The chicken would eat the grain.
09:53So we'll just set the chicken there next to the arrow.
09:56So, who might eat the chicken?
09:58The fox.
09:59The fox would eat the chicken.
10:01So we'll put the fox down here like that.
10:05OK, let's try another one.
10:06Now, for this one, I'd like you guys to run around the garden
10:10to try and find the animals
10:12and then put them in the spot where they're meant to go.
10:14OK, so here we have a pile of leaves.
10:18Now, from our search, who do we know eats leaves?
10:20Slugs.
10:21Well done, Tyler.
10:23They're doing really well.
10:25Off you go.
10:29Oh, you're getting hotter.
10:36The leaves are eaten by the slugs.
10:38OK, what type of animal do we think would like to nibble on the slug?
10:43A bird.
10:56Brilliant.
10:57So, Tyler, where do you think the bird goes?
11:00Down here.
11:01That's right.
11:02Birds like to eat slugs.
11:04So, from this we can see that leaves provide food for the slug
11:08and the slug provides food for the bird.
11:11So this is a food chain.
11:13And all the plants and animals in a food chain are linked together.
11:16So what would happen if one of these things was taken away,
11:19like the slug?
11:21There wouldn't be much food for the birds.
11:24All the leaves would pile up.
11:25Yes, almost all animals are part of a food chain.
11:29So if you were to take just one thing away,
11:32it would affect everything else in a bad way.
11:34So slugs really are very important
11:36because they're actually part of a few food chains.
11:39So if you were to take the slugs out of the garden,
11:41then other animals that eat them, like hedgehogs and frogs,
11:44would have less to eat.
11:46And they might stop visiting your garden.
11:48So what do you think about the slugs now?
11:49It's really important to have slugs in your garden.
11:53Yeah, they are really important.
11:55Hi, Dad.
11:56Hi.
11:56We've just been finding out that another reason why there's slugs in the garden
11:59is because they're part of a food chain.
12:01I still wish they wouldn't eat my plants.
12:03Ah, well, I did think you'd say that.
12:05So I've brought you a little present.
12:07Eggshells in a plastic bottle.
12:09Don't worry.
12:10These will help to protect the plants you don't want the slugs to munch,
12:13but the slugs can still live happily in the garden.
12:15So shall we go and help protect your dad's plants?
12:18Yeah.
12:19Yeah.
12:23So the eggshells stop the slugs from coming too close
12:26because they've got rough edges
12:28and the plastic bottle protects the plants.
12:31So the slugs can live in the garden,
12:32but they won't eat your dad's plants.
12:34So everyone's happy.
12:35Now, Tyler, you asked,
12:37why do we have slugs in our garden?
12:38And I think we've answered your question.
12:40We have slugs in our gardens
12:42because they do some important jobs.
12:44They eat up lots of rotting stuff
12:46like old leaves and compost
12:48and they also provide food for other animals,
12:50which all helps to protect our planet.
12:53So you'll take special care of them now, won't you?
12:55Yes, Nina.
12:56We like slugs now.
12:58Oh, brilliant.
12:59So I'll see you later, guys.
13:00Bye.
13:01Bye, Nina.
13:06Help protect our planet.
13:09Go eco.
13:10Go eco.
13:32Ah, it's been such a great day, man.
13:35I loved the slug search in the garden.
13:38It was great fun seeing the giant slug
13:41under the magnifying glass.
13:43Hee-hee.
13:44I really enjoyed myself today,
13:46although the compost heap was a bit whiffy.
13:49I've had a fabby day.
13:51I really liked the food chain game.
13:54That was fun.
13:55It's been a marvellous day,
13:57especially when everyone put eggshells
13:59and plastic bottles round the plants to protect them.
14:02We've had a sensational time.
14:04I hope you've enjoyed it too.
14:05See you again soon.
14:07Bye.
14:08Bye-bye.
14:08Who knows why?
14:13Go eco.
14:15Go eco.
14:15Go eco.
14:15Go eco eco.
