0:00:04 > 0:00:09Hi, guys.
0:00:09 > 0:00:14Martin here with a jam-packed show on the way.
0:00:14 > 0:00:16Plus the school kids experiencing what life was like in the
0:00:16 > 0:00:17World War One trenches.
0:00:17 > 0:00:20It's Newsround.
0:00:20 > 0:00:22But first, one of Britain's most famous landmarks
0:00:22 > 0:00:25has been turned red today as the events to mark 100 years since
0:00:25 > 0:00:29the start of World War I continue.
0:00:29 > 0:00:30More than 800,000 clay poppies are being placed at the Tower of London
0:00:32 > 0:00:34with Prince Harry and the Duke and Duchess
0:00:34 > 0:00:37of Cambridge all planting one.
0:00:37 > 0:00:39They're designed to remember each and every British and Commonwealth
0:00:39 > 0:00:43soldier who died in the war.
0:00:43 > 0:00:45This is one of the ways I can actually explain
0:00:45 > 0:00:48to people how many people died in a way that everyone can see,
0:00:48 > 0:00:52because it is a flower, it is a person, it is not just a number.
0:00:52 > 0:00:55You can visualise it all.
0:00:55 > 0:00:57Well, many of those soldiers in the Great War spent lots
0:00:57 > 0:00:59of time in the trenches.
0:00:59 > 0:01:02They were special ditches dug into the ground where soldiers
0:01:02 > 0:01:03fought and lived.
0:01:03 > 0:01:06In the next of our special reports on the 100th
0:01:06 > 0:01:09anniversary of the conflict, Ricky's been back to one of the key battle
0:01:09 > 0:01:13sites in Belgium to find out more.
0:01:18 > 0:01:21Here at Vimy Ridge, you get a real sense of how close
0:01:21 > 0:01:23the fighting would have been.
0:01:23 > 0:01:26On this side, you had the Allied troops, so the Canadians, and on
0:01:26 > 0:01:32this side, just a couple of metres away, the Germans in their trenches.
0:01:32 > 0:01:35In the middle, you had No Man's Land, and you can
0:01:35 > 0:01:37see the devastation that would've been caused by the bombs and the
0:01:37 > 0:01:43shelling with those giant craters.
0:01:43 > 0:01:46This is the very first time you have visited a trench.
0:01:46 > 0:01:48What do you girls make of it?
0:01:48 > 0:01:50It would've been quite frightening.
0:01:50 > 0:01:55You can't go back once you started to be part of the war.
0:01:55 > 0:01:57You can't go back and do something different, you have
0:01:57 > 0:01:59to carry on doing it.
0:01:59 > 0:02:03It would have been very noisy and muddy.
0:02:03 > 0:02:05There would have been layers of earth everywhere,
0:02:05 > 0:02:10all spread around.
0:02:10 > 0:02:12Imagine the firing and all the bullets that would've
0:02:12 > 0:02:12flown over here.
0:02:12 > 0:02:18You would have always had to seek cover and duck down.
0:02:18 > 0:02:20You would've had to make sure no-one got shot by the opposition.
0:02:20 > 0:02:23And you would've been really tired, so having to sleep
0:02:23 > 0:02:24in the trenches.
0:02:24 > 0:02:27Can you imagine what life would have been like for those soldiers?
0:02:27 > 0:02:30Just awful sleeping in the trenches when you know you could just get
0:02:30 > 0:02:36shot sleeping in there is really frightening.
0:02:36 > 0:02:37Thanks, Ricky.
0:02:37 > 0:02:40And you can see more on the trench tactics that helped win the war,
0:02:40 > 0:02:44along with loads more about World War I, on the Newsround website,
0:02:44 > 0:02:47including what the soldiers wore in battle, how many people fought and
0:02:47 > 0:02:51died, and the story of Horace, who went off to war aged 14.
0:02:55 > 0:02:57They're incredible stories, and ones that the Prime Minister,
0:02:57 > 0:02:59David Cameron, says he's been teaching his own children about.
0:02:59 > 0:03:02Speaking at a special event in Belgium, he told Newsround how
0:03:02 > 0:03:04he's approached explaining some of the difficult things that
0:03:04 > 0:03:08happened in the war.
0:03:08 > 0:03:10Were your children fascinated by what happened?
0:03:10 > 0:03:12Are they intrigued and want to know more?
0:03:12 > 0:03:12They do.
0:03:12 > 0:03:16When you tell them about how old the people were who volunteered, when
0:03:16 > 0:03:19you tell them how many people died, when you tell them about some of
0:03:19 > 0:03:22the horrible things that happened, they do get interested and try to
0:03:22 > 0:03:25understand how it could happen.
0:03:25 > 0:03:28What have you taken from today so far?
0:03:28 > 0:03:32It is important to commemorate those who gave their lives.
0:03:32 > 0:03:36It is important to learn the lessons of how important it is that we find
0:03:36 > 0:03:39other ways other than war in order to solve our problems.
0:03:39 > 0:03:44But it is also important to remember that the First World War changed
0:03:44 > 0:03:47our world, some in bad ways,
0:03:47 > 0:03:50but in some good ways, such as advances for medicine and women.
0:03:50 > 0:03:53There were some good things that happened.
0:03:53 > 0:03:54Thank you for talking to us.
0:03:54 > 0:03:58Pleasure.
0:03:58 > 0:04:01Next, to a dramatic rescue of two hikers who got stuck in the
0:04:01 > 0:04:02mountains of California in America.
0:04:02 > 0:04:05This footage shows one of the men waving his shirt to get
0:04:05 > 0:04:09the helicopters' attention.
0:04:09 > 0:04:11have fallen down part of the cliff.
0:04:11 > 0:04:16Both walkers were picked up and taken to safety.
0:04:16 > 0:04:18And finally to the schoolboys who struck gold during
0:04:18 > 0:04:20a treasure hunt in Northumberland.
0:04:20 > 0:04:23This 4,000-year-old golden hair ornament was discovered during
0:04:23 > 0:04:26a dig at an ancient burial site.
0:04:26 > 0:04:29One of the boys who found it said he started dancing with joy
0:04:29 > 0:04:33when they dug it up!
0:04:33 > 0:04:36Pet lovers - there's just time to tell you how you can get involved
0:04:36 > 0:04:37in the programme.
0:04:37 > 0:04:39We want you to get in touch and tell us
0:04:39 > 0:04:42if you're taking your pooches, cats, rabbits or whatever on holiday with
0:04:42 > 0:04:44you this year, and if so where to.
