Hi, guys.

Martin here with a jam-packed show on the way.

Plus the school kids experiencing what life was like in the

World War One trenches.

It's Newsround.

But first, one of Britain's most famous landmarks

has been turned red today as the events to mark 100 years since

the start of World War I continue.

More than 800,000 clay poppies are being placed at the Tower of London

with Prince Harry and the Duke and Duchess

of Cambridge all planting one.

They're designed to remember each and every British and Commonwealth

soldier who died in the war.

This is one of the ways I can actually explain

to people how many people died in a way that everyone can see,

because it is a flower, it is a person, it is not just a number.

You can visualise it all.

Well, many of those soldiers in the Great War spent lots

of time in the trenches.

They were special ditches dug into the ground where soldiers

fought and lived.

In the next of our special reports on the 100th

anniversary of the conflict, Ricky's been back to one of the key battle

sites in Belgium to find out more.

Here at Vimy Ridge, you get a real sense of how close

the fighting would have been.

On this side, you had the Allied troops, so the Canadians, and on

this side, just a couple of metres away, the Germans in their trenches.

In the middle, you had No Man's Land, and you can

see the devastation that would've been caused by the bombs and the

shelling with those giant craters.

This is the very first time you have visited a trench.

What do you girls make of it?

It would've been quite frightening.

You can't go back once you started to be part of the war.

You can't go back and do something different, you have

to carry on doing it.

It would have been very noisy and muddy.

There would have been layers of earth everywhere,

all spread around.

Imagine the firing and all the bullets that would've

flown over here.

You would have always had to seek cover and duck down.

You would've had to make sure no-one got shot by the opposition.

And you would've been really tired, so having to sleep

in the trenches.

Can you imagine what life would have been like for those soldiers?

Just awful sleeping in the trenches when you know you could just get

shot sleeping in there is really frightening.

Thanks, Ricky.

And you can see more on the trench tactics that helped win the war,

along with loads more about World War I, on the Newsround website,

including what the soldiers wore in battle, how many people fought and

died, and the story of Horace, who went off to war aged 14.

They're incredible stories, and ones that the Prime Minister,

David Cameron, says he's been teaching his own children about.

Speaking at a special event in Belgium, he told Newsround how

he's approached explaining some of the difficult things that

happened in the war.

Were your children fascinated by what happened?

Are they intrigued and want to know more?

They do.

When you tell them about how old the people were who volunteered, when

you tell them how many people died, when you tell them about some of

the horrible things that happened, they do get interested and try to

understand how it could happen.

What have you taken from today so far?

It is important to commemorate those who gave their lives.

It is important to learn the lessons of how important it is that we find

other ways other than war in order to solve our problems.

But it is also important to remember that the First World War changed

our world, some in bad ways,

but in some good ways, such as advances for medicine and women.

There were some good things that happened.

Thank you for talking to us.

Pleasure.

Next, to a dramatic rescue of two hikers who got stuck in the

mountains of California in America.

This footage shows one of the men waving his shirt to get

the helicopters' attention.

have fallen down part of the cliff.

Both walkers were picked up and taken to safety.

And finally to the schoolboys who struck gold during

a treasure hunt in Northumberland.

This 4,000-year-old golden hair ornament was discovered during

a dig at an ancient burial site.

One of the boys who found it said he started dancing with joy

when they dug it up!

Pet lovers - there's just time to tell you how you can get involved

in the programme.

We want you to get in touch and tell us

if you're taking your pooches, cats, rabbits or whatever on holiday with

you this year, and if so where to.

Head to the Newsround website to find out how to get involved now.

That's all from me, but we'll be back bright and early tomorrow.

See you.
