0:00:08 > 0:00:09- ..to sing and dance.
0:00:12 > 0:00:13- You and me.
0:00:15 > 0:00:19- In TiPiNi!
0:00:23 > 0:00:26- There are quarries around us here.
0:00:26 > 0:00:28- We've pitched the tepee - in Snowdonia.
0:00:29 > 0:00:33- We're looking for new friends - in a large village called Bethesda.
0:00:33 > 0:00:36- Who will our friends be today?
0:00:36 > 0:00:39- Hello, my name is Beca.
0:00:40 > 0:00:41- I'm Math.
0:00:42 > 0:00:43- I'm Elin.
0:00:43 > 0:00:45- I'm Elin.- - And I'm Oscar.
0:00:46 > 0:00:49- I'm Sylvie, - and I'm telling the story.
0:00:50 > 0:00:52- They're great. - We'll go to look for them.
0:00:53 > 0:00:57- But first, let's ask WiCiNi - what we can see in Bethesda.
0:00:58 > 0:01:03- In the Bethesda area years ago, - there were lots of quarries.
0:01:03 > 0:01:05- The quarrymen dug for slate.
0:01:06 > 0:01:09- The slates were transported - through this tunnel...
0:01:10 > 0:01:12- ..called Tynal Tywyll - - the dark tunnel.
0:01:13 > 0:01:15- Today, you can walk through it.
0:01:17 > 0:01:21- Nearby are the pretty valleys - and mountains of Snowdonia.
0:01:21 > 0:01:23- Why not visit Cwm Idwal?
0:01:30 > 0:01:32- We're in Tynal Tywyll!
0:01:34 > 0:01:39- Kizzy and Kai have asked us - to meet in Tynal Tywyll.
0:01:39 > 0:01:41- This is Tynal Tywyll.
0:01:41 > 0:01:47- There are lots of tunnels here, - but this is Tynal Tywyll.
0:01:47 > 0:01:50- Do we need to go through the tunnel?
0:01:52 > 0:01:54- Maybe they're there.
0:01:54 > 0:01:55- Maybe.
0:01:56 > 0:02:00- Luckily, the tunnel has a roof, - because the rain is pouring down.
0:02:04 > 0:02:06- They're coming at last.
0:02:07 > 0:02:08- Hello!
0:02:08 > 0:02:10- Hello!- - Hello, children. Are you OK?
0:02:11 > 0:02:13- Let's go into the song.
0:02:18 > 0:02:20- # Number one, dance freely
0:02:23 > 0:02:25- # Dance freely #
0:02:28 > 0:02:32- Today, this is - a walking and cycling path.
0:02:35 > 0:02:37- But what was its purpose - a long time ago?
0:02:39 > 0:02:41- If they hadn't built the tunnel...
0:02:42 > 0:02:45- ..the steam train - would have had to stop over there...
0:02:45 > 0:02:48- ..because there was a mountain here.
0:02:48 > 0:02:52- Why did the train - have to go through the mountain?
0:02:52 > 0:02:56- It carried slates - to make roofs all over the world.
0:02:56 > 0:02:57- What kind of train was it?
0:02:57 > 0:02:59- What kind of train was it?- - A steam train.
0:02:59 > 0:03:03- They put coal on the fire...
0:03:03 > 0:03:07- ..and the coal made smoke.
0:03:07 > 0:03:11- They put the coal on a shovel - and threw it into the fire.
0:03:15 > 0:03:17- What noise does a steam train make?
0:03:18 > 0:03:19- Toot toot!
0:03:19 > 0:03:20- Toot toot!- - Choo choo!
0:03:20 > 0:03:26- The smoke from the train - turned the tunnel roof black.
0:03:26 > 0:03:28- Where does this tunnel lead?
0:03:28 > 0:03:32- Where does this tunnel lead?- - From the river to Tregarth.
0:03:33 > 0:03:35- I like the echo in the tunnel.
0:03:35 > 0:03:40- I like shouting - and hearing myself shouting back.
0:03:40 > 0:03:41- Hello!
0:03:42 > 0:03:43- Hello!
0:03:44 > 0:03:45- Hello!
0:03:46 > 0:03:47- Hello!
0:03:47 > 0:03:50- I know. Let's play the echo game.
0:03:51 > 0:03:52- Hello!
0:03:52 > 0:03:53- Hello!
0:03:53 > 0:03:54- Hello!- - Mee!
0:03:55 > 0:03:56- Mee!
0:04:09 > 0:04:13- # Here in the dark tunnel
0:04:16 > 0:04:20- # Lights shining overhead
0:04:23 > 0:04:27- # Slates under my feet
0:04:31 > 0:04:34- # And the echo of the train
0:04:37 > 0:04:41- # Here in the dark tunnel
0:04:44 > 0:04:48- # Lights shining overhead
0:04:52 > 0:04:55- # Slates under my feet
0:04:59 > 0:05:04- # And the echo of the train #
0:05:12 > 0:05:16- # Thank you, friends, thanks a lot
0:05:16 > 0:05:20- # For the warm welcome - you gave to us
0:05:20 > 0:05:24- # There's nothing like new friends
0:05:25 > 0:05:28- # Seeing each other every other day
0:05:29 > 0:05:32- # But when we are apart
0:05:33 > 0:05:37- # Remember us in dance and song #
0:05:39 > 0:05:42- Thank you, friends. It's been great.
0:05:42 > 0:05:44- Goodbye, friends!
0:05:44 > 0:05:45- Goodbye, friends!- - Ta-ta!
0:05:58 > 0:06:03- Today, we've asked Kizzy and Kai - to meet us in Snowdonia.
0:06:03 > 0:06:05- We're in Cwm Idwal.
0:06:05 > 0:06:08- The River Ogwen runs from here...
0:06:09 > 0:06:14- ..down the valley, through Bethesda - and into the sea at the far end.
0:06:14 > 0:06:18- This valley is called Nant Ffrancon.
0:06:18 > 0:06:23- This is Nant Ffrancon, - and it was all carved out by ice.
0:06:23 > 0:06:24- This is Guto.
0:06:25 > 0:06:29- He's the warden - who looks after this area.
0:06:29 > 0:06:34- He knows all there is to know - about mountains and valleys.
0:06:35 > 0:06:40- If you come with me, I'll try - to explain how mountains form...
0:06:40 > 0:06:43- ..and how ice - shaped what's around us.
0:06:43 > 0:06:48- We're making a model - of the area in the sand.
0:06:51 > 0:06:52- Abercaseg Mountain!
0:06:55 > 0:06:58- Who can tell me - what happens to the water?
0:06:58 > 0:07:01- When it rains on the mountain, - where does the water go?
0:07:02 > 0:07:03- A river.
0:07:03 > 0:07:04- A stream.
0:07:04 > 0:07:07- Yes, we have them on the mountain.
0:07:07 > 0:07:12- Take your turn - and make a line down the mountain.
0:07:12 > 0:07:15- That will be your river.
0:07:17 > 0:07:21- That's what happened - before the Ice Age.
0:07:21 > 0:07:23- It rained on the mountains...
0:07:24 > 0:07:29- ..and the rain eroded the rock - and formed rivers or streams.
0:07:29 > 0:07:34- Next, we'll see - how ice shapes the terrain.
0:07:35 > 0:07:39- Put your hand - at the top of your stream...
0:07:39 > 0:07:43- ..press into the sand - and pull your hand down.
0:07:46 > 0:07:47- Excellent.
0:07:47 > 0:07:53- We're left with exactly the same - as we saw on the model.
0:07:53 > 0:07:56- Deep valleys with flat floors.
0:07:57 > 0:08:00- This is like Cwm Bochlwyd - or Cwm Idwal.
0:08:00 > 0:08:04- You've hit a hard section - and the glacier had to rise.
0:08:04 > 0:08:07- In that hole, a lake would form.
0:08:07 > 0:08:13- Look down Nant Ffrancon - and it has a flat floor...
0:08:13 > 0:08:15- ..and steep sides.
0:08:15 > 0:08:18- The processes we spoke about, - these glaciers...
0:08:19 > 0:08:22- ..is happening now - in the world's highest mountains.
0:08:22 > 0:08:24- It happened here long ago.
0:08:24 > 0:08:27- We see traces of it today.
0:08:27 > 0:08:32- And here it is, - the real Nant Ffrancon today.
0:08:32 > 0:08:36- The river flows - along the valley floor...
0:08:37 > 0:08:41- ..and the mountains - rising steeply on both sides.
0:08:43 > 0:08:48- Remember that the weather can change - unexpectedly in the mountains.
0:08:48 > 0:08:53- Take sunny and wet weather clothing - with you when you visit.
0:09:08 > 0:09:12- And to carry everything, - the biggest rucksack you can carry.
0:09:14 > 0:09:18- # The valley was formed
0:09:18 > 0:09:22- # By ice a long time ago
0:09:23 > 0:09:26- # The steep mountains
0:09:27 > 0:09:31- # Look down on the green pastures
0:09:40 > 0:09:44- # La la la la la #
0:09:45 > 0:09:48- Near Bethesda, - the past echoes in Tynal Tywyll.
0:09:50 > 0:09:53- A long time ago as well, - Nant Ffrancon was created by ice.
0:09:54 > 0:09:57- What a nice place - to learn about yesterday.
0:10:01 > 0:10:03- Today is our day in the tepee.
0:10:03 > 0:10:05- How exciting!
0:10:06 > 0:10:11- I thought - it was going to be a small tent.
0:10:11 > 0:10:13- But now I've seen it, it's big.
0:10:14 > 0:10:16- My favourite thing is Kai!
0:10:17 > 0:10:19- I'm sure that Kai is happy!
0:10:19 > 0:10:22- It's time - for a dance lesson with Kai.
0:10:22 > 0:10:25- Yay!
0:10:38 > 0:10:39- Here you are.
0:10:39 > 0:10:40- Here you are.- - Oh, wow!
0:10:41 > 0:10:43- That's so pretty.
0:10:43 > 0:10:46- I love them. Thank you!
0:10:51 > 0:10:54- Here come the gang!
0:10:54 > 0:10:58- Off we all go to sing and dance!
0:11:13 > 0:11:15- It's lovely to see you.
0:11:15 > 0:11:17- Let's sing about Bethesda.
0:11:18 > 0:11:20- # Hear, hear the voices
0:11:20 > 0:11:23- # Calling and calling again
0:11:27 > 0:11:33- # Our voices reverberate the history - when you hear the echo
0:11:37 > 0:11:42- # The trains carries slates - through the dark tunnel
0:11:46 > 0:11:52- # Now, Tynal Tywyll is a path - for us and our friends
0:11:56 > 0:11:57- # Bethesda
0:11:58 > 0:12:01- # Is full of noise
0:12:01 > 0:12:05- # It echoes all across the world
0:12:06 > 0:12:11- # Hear, hear the legends - in Cwm Idwal, and visit the lake
0:12:15 > 0:12:21- # Glaciers shaped it, - but no legends live here
0:12:25 > 0:12:31- # Here, there are treasures - prettier than any other
0:12:34 > 0:12:40- # An innocent little flower, - the Snowdon lily
0:12:44 > 0:12:45- # Bethesda
