0:01:05 > 0:01:07# Oh, yeah! #
0:01:08 > 0:01:11- Hi, everyone! - ALL: Hi, Nina!
0:01:11 > 0:01:14I have an exciting experiment to show you.
0:01:14 > 0:01:18I'm going to try and move water from one glass to another
0:01:18 > 0:01:20without touching any of the glasses.
0:01:20 > 0:01:23Do you think I can do it?
0:01:23 > 0:01:24ALL: No!
0:01:24 > 0:01:27It does sound tricky, doesn't it?
0:01:27 > 0:01:29Watch carefully!
0:01:29 > 0:01:33First, I'm going to pop some green food colouring into the water
0:01:33 > 0:01:35just so we can see it better.
0:01:35 > 0:01:39Great, I'll give that a wee stir.
0:01:39 > 0:01:43Now, I'm going to take this long piece of kitchen paper
0:01:43 > 0:01:45and sit it over both glasses,
0:01:45 > 0:01:47and let's see what happens.
0:01:47 > 0:01:50Look! The water's soaking into the paper,
0:01:50 > 0:01:52heading to the other glass!
0:01:52 > 0:01:55Ho-ho! But, what do you think will happen
0:01:55 > 0:01:59when the water gets to the edge of the paper?
0:01:59 > 0:02:02Do you think it will stop or will it drip?
0:02:02 > 0:02:03THEY SHOUT ANSWERS
0:02:03 > 0:02:07Oh, not sure? We're about to find out.
0:02:09 > 0:02:10Oh! It's dripping.
0:02:10 > 0:02:14Yay! I managed to move water from one glass to another
0:02:14 > 0:02:17without touching any of the glasses
0:02:17 > 0:02:19When we put the paper in,
0:02:19 > 0:02:24the water climbed all the way along into the other glass.
0:02:24 > 0:02:28This climbing of the water is called capillary action
0:02:28 > 0:02:30and it's very useful in nature.
0:02:30 > 0:02:32It's how trees get water from the ground.
0:02:35 > 0:02:37BEEP! BEEP!
0:02:37 > 0:02:41I hear a beep, I see a flash, I wonder what they're going to ask.
0:02:46 > 0:02:49Hello, Nina. My name's Tyla and I've got a question.
0:02:49 > 0:02:52Why do we have slugs in our garden?
0:02:52 > 0:02:56That's a great question, Tyla. Why do we have slugs in our garden?
0:02:56 > 0:03:01We'll have lots of fun with this. Thanks, Tyla. I'll be over soon.
0:03:01 > 0:03:03- See you soon, Nina. Bye.- Bye!
0:03:03 > 0:03:07Well, I'm going to need help to answer this one
0:03:07 > 0:03:10and I know just who to ask. OK, Neurons, time to get to work.
0:03:10 > 0:03:12BUZZING
0:03:26 > 0:03:28ALL: Neurons at the ready, Nina.
0:03:28 > 0:03:32OK, today's question is - why do we have slugs in our garden?
0:03:32 > 0:03:36Which Neuron do you think will be most useful in finding the answer?
0:03:36 > 0:03:39- Me, me!- Me!- Me!
0:03:39 > 0:03:42Will it be fabulous Felix?
0:03:42 > 0:03:46I can help so very much, if you need the sense of touch.
0:03:46 > 0:03:48Will it be beautiful Belle?
0:03:48 > 0:03:50I send messages to brain from ear.
0:03:50 > 0:03:53if there's a sound, I'll help you hear!
0:03:53 > 0:03:54Will it be lovely Luke?
0:03:54 > 0:03:56Looking or seeing, day or night,
0:03:56 > 0:03:59I'll help you with your sense of sight.
0:03:59 > 0:04:01Will it be awesome Ollie?
0:04:01 > 0:04:04If it's pongy or whiffy, but you can't tell,
0:04:04 > 0:04:07my messages help your sense of smell.
0:04:07 > 0:04:08Or will it be baby Bud?
0:04:08 > 0:04:13Sour, salty, bitter or sweet, I'm your taste buddy when you eat!
0:04:17 > 0:04:19It's Luke!
0:04:19 > 0:04:27ALL: Go Luke, go Luke, go Luke!
0:04:27 > 0:04:30Cool, Nina. I'll be looking out to help ya!
0:04:30 > 0:04:34Today's question is - why do we have slugs in our garden?
0:04:34 > 0:04:38Slugs are something we SEE in a garden so Luke is helping.
0:04:38 > 0:04:41But standby Neurons, I'll need all of you today!
0:04:44 > 0:04:45OK...
0:04:45 > 0:04:46Let's go!
0:05:07 > 0:05:10Tyla will be finding out all about slugs.
0:05:10 > 0:05:14Little tiny slimy slugs, great big hungry slugs and shiny slugs
0:05:14 > 0:05:16of all shapes and sizes!
0:05:16 > 0:05:21Today, for one day only, Tyla, Dad and cousin Jenai become...
0:05:21 > 0:05:24..The Experimenters!
0:05:24 > 0:05:27- Hi, everyone! - ALL: Hi, Nina!
0:05:27 > 0:05:30- You look busy!- We're putting food out for the birds.
0:05:30 > 0:05:33You'll have loads of birds in the garden today
0:05:33 > 0:05:37and speaking of having things in the garden, Tyla, your question is -
0:05:37 > 0:05:40why do we have slugs in our garden?
0:05:40 > 0:05:42- Why slugs?- I don't like slugs
0:05:42 > 0:05:46because Dad gets annoyed cos they eat his plants.
0:05:46 > 0:05:49We should find out more about them
0:05:49 > 0:05:51and work out why they're in the garden.
0:05:51 > 0:05:53Are you ready for a slug search?!
0:05:53 > 0:05:54BOTH: Yeah!
0:05:57 > 0:06:00OK, Tyla, to answer your question -
0:06:00 > 0:06:02why do we have slugs in our garden? -
0:06:02 > 0:06:06we're going to try and find out where the slugs live.
0:06:06 > 0:06:08- Are you up for the challenge? - Yes, Nina!
0:06:08 > 0:06:11Let's get searching!
0:06:17 > 0:06:20Nina, there's a slug on that cabbage leaf!
0:06:20 > 0:06:26Ooh. Good work, Tyla. Let's have a closer look.
0:06:28 > 0:06:30Oh! It's an enormous slug!
0:06:30 > 0:06:32Calm down, Felix, man.
0:06:32 > 0:06:37It just looks that way because Nina's using a magnifying glass.
0:06:37 > 0:06:41That makes things look much bigger, so we can see them better.
0:06:41 > 0:06:44So we don't forget where this slug is,
0:06:44 > 0:06:47let's mark the spot with one of these flags.
0:06:49 > 0:06:50Excellent.
0:06:51 > 0:06:53There's one, Nina!
0:06:53 > 0:06:56Oh, so there is. Well done, Jenai.
0:06:56 > 0:06:58Let's have a closer look.
0:06:58 > 0:07:00Oooh!
0:07:00 > 0:07:05Ooh, Nina, that compost heap is really whiffy! Yuck!
0:07:05 > 0:07:11I agree, Ollie, but a compost heap is a great place for recycling.
0:07:11 > 0:07:13You can put lots of garden waste in it,
0:07:13 > 0:07:17like grass cuttings or even old vegetable peelings.
0:07:17 > 0:07:19Over time it rots away to become compost,
0:07:19 > 0:07:24which you can then use to put in the garden to feed the plants.
0:07:24 > 0:07:27But a compost heap can be a bit smelly.
0:07:27 > 0:07:32But this slug doesn't seem to mind. He's pretty happy living in it.
0:07:32 > 0:07:35So, let's pop a flag in and go and find some more slugs.
0:07:37 > 0:07:40Hey, look at that, Nina. It's a slimy trail.
0:07:40 > 0:07:46Something tells me you might find something in there if you look.
0:07:46 > 0:07:47You're right, Luke.
0:07:47 > 0:07:51Slugs and snails can sometimes leave a slimy trail behind.
0:07:51 > 0:07:54So, shall we follow it to see where it leads?
0:07:54 > 0:07:56OK...
0:07:58 > 0:08:01Oh, wow! We've found another one. Fantastic.
0:08:01 > 0:08:05Ho-ho! He looks really comfy in these old rotting leaves.
0:08:05 > 0:08:08Let's put the last flag in...
0:08:10 > 0:08:12Ah, great work, Experimenters!
0:08:12 > 0:08:16Let's take a look at where we've put the flags
0:08:16 > 0:08:19and that'll tell us where all the slugs live.
0:08:19 > 0:08:23- In the old rotten leaves. - In the smelly compost heap.
0:08:23 > 0:08:25And on the cabbages.
0:08:25 > 0:08:29That's right and the reason we've found slugs in these places
0:08:29 > 0:08:32is because they eat all of these things.
0:08:32 > 0:08:34Slugs eat some things we don't want them to,
0:08:34 > 0:08:36like your dad's cabbages,
0:08:36 > 0:08:39but they also eat useful things, that we want rid of,
0:08:39 > 0:08:41like old leaves and rotten vegetables.
0:08:41 > 0:08:43Eugh! That would taste horrible!
0:08:43 > 0:08:45Not to slugs, though, Bud.
0:08:45 > 0:08:48That would be like a fancy dinner to them.
0:08:48 > 0:08:52Through our slug search, we found out we have slugs in the garden
0:08:52 > 0:08:54because there's lots for them to eat.
0:08:54 > 0:08:56So, slugs can be very useful
0:08:56 > 0:09:01and there's another reason why slugs are good to have around.
0:09:01 > 0:09:03To explain why, we can play another game.
0:09:03 > 0:09:04BOTH: Yay!
0:09:07 > 0:09:10To find another reason that slugs are in the garden
0:09:10 > 0:09:14we'll play a game called The Food Chain Game!
0:09:14 > 0:09:17- Have you heard of a food chain before?- No.
0:09:17 > 0:09:20It's all about what animals eat.
0:09:21 > 0:09:24Here I have some grain...
0:09:26 > 0:09:27..and that's there.
0:09:28 > 0:09:32I'm gonna sit this arrow here.
0:09:32 > 0:09:38Now, which of these two animals do you think eats the grain?
0:09:38 > 0:09:40The fox or the chicken?
0:09:40 > 0:09:46BUD: Erm...um... Hold on a minute, I'm sure I know the answer...
0:09:46 > 0:09:47The chicken.
0:09:47 > 0:09:50BUD: Exactly what I would have said.
0:09:50 > 0:09:54The chicken would eat the grain, so we'll sit the chicken there,
0:09:54 > 0:09:56next to the arrow.
0:09:56 > 0:09:58- So, who might eat the chicken? - The fox.
0:09:58 > 0:10:03The fox would eat the chicken, so we'll put the fox down here.
0:10:03 > 0:10:06OK, let's try another one. For this one,
0:10:06 > 0:10:11I'd like you guys to run around the garden to try and find the animals
0:10:11 > 0:10:13and put them where they're meant to go.
0:10:13 > 0:10:19Here we have a pile of leaves. Who do we know eats leaves?
0:10:19 > 0:10:20Slugs.
0:10:20 > 0:10:24BELLE: Well done, Tyla! They're doing really well.
0:10:24 > 0:10:25Off you go!
0:10:28 > 0:10:31Oh, you're getting hotter!
0:10:35 > 0:10:38The leaves are eaten by the slugs.
0:10:38 > 0:10:43OK, what type of animal do we think would like to eat the slug?
0:10:43 > 0:10:44A bird!
0:10:56 > 0:10:59Brilliant! Tyra, where do you think the bird goes?
0:10:59 > 0:11:01Down here.
0:11:01 > 0:11:04That's right! Birds like to eat slugs.
0:11:04 > 0:11:08So, we can see that leaves provide food for the slug,
0:11:08 > 0:11:11and the slug provides food for the bird.
0:11:11 > 0:11:15This is a food chain and all the plants and animals in it are linked.
0:11:15 > 0:11:19What would happen if one of these things was taken away,
0:11:19 > 0:11:20like the slug?
0:11:20 > 0:11:25- There wouldn't be food for the birds! - The leaves would pile up!
0:11:25 > 0:11:28Yes, almost all animals are part of a food chain.
0:11:28 > 0:11:30If you take one thing away,
0:11:30 > 0:11:33it effects everything else in a bad way.
0:11:33 > 0:11:38So slugs are very important because they're part of a few food chains.
0:11:38 > 0:11:41If you took slugs out of the garden,
0:11:41 > 0:11:45animals that eat them like hedgehogs and frogs have less to eat
0:11:45 > 0:11:47and might stop visiting.
0:11:47 > 0:11:49What do you think about slugs now?
0:11:49 > 0:11:52It's important to have slugs in your garden.
0:11:52 > 0:11:55- Yeah, they are really important. Hi, Dad!- Hi.
0:11:55 > 0:11:58Another reason why slugs are in the garden
0:11:58 > 0:12:00is because they're part of a food chain.
0:12:00 > 0:12:03I still wish they wouldn't eat my plants.
0:12:03 > 0:12:06OK, well, I've brought a present.
0:12:06 > 0:12:08Eggshells and a plastic bottle?
0:12:08 > 0:12:11Don't worry! These help protect the plants
0:12:11 > 0:12:15but the slugs can still live happily in the garden.
0:12:15 > 0:12:18- Shall we protect your dad's plants? - Yeah!
0:12:23 > 0:12:26The eggshells stop the slugs from coming too close
0:12:26 > 0:12:30and the plastic bottle protects the plants.
0:12:30 > 0:12:33The slugs can live here, but won't eat your dad's plants.
0:12:33 > 0:12:36Everyone's happy. Tyla, you asked,
0:12:36 > 0:12:39"Why do we have slugs in our garden?"
0:12:39 > 0:12:43We have slugs because they do some important jobs.
0:12:43 > 0:12:47They eat up lots of rotting stuff like old leaves and compost,
0:12:47 > 0:12:51and they also provide food for other animals.
0:12:51 > 0:12:53It all helps protect our planet!
0:12:53 > 0:12:58- You'll take care of them now. - Yes, Nina!- We like slugs now.
0:12:58 > 0:13:01- See you later, guys. Bye! - BOTH: Bye, Nina!

0:13:34 > 0:13:37I loved the slug search in the garden!
0:13:37 > 0:13:43It was great fun seeing the giant slug under the magnifying glass.
0:13:43 > 0:13:45I really enjoyed myself today
0:13:45 > 0:13:48although the compost heap was a bit whiffy!
0:13:48 > 0:13:54I've had a fabby day! I really liked the food chain game. That was fun!
0:13:54 > 0:13:56It's been a marvellous day.
0:13:56 > 0:14:00Especially when everyone put eggshells and plastic bottles
0:14:00 > 0:14:01round the plants.
