Hi, I'm Leah, and this is Newsround.

On the way...

With summer holidays on the horizon, we ask where you guys like to go.

Why these boys are wearing skirts to school.

And way to glow, find out what causes this amazing sight.

First this afternoon, Liam Payne, Rita Ora,

Stormzy and Leona Lewis.

Just a few of the names who are helping to raise

money for those affected by the Grenfell Tower block fire

which happened last week.

The singers recorded Bridge Over Troubled Water

to support victims' families.

The song hit the number one spot on iTunes just two hours

after it was released.

X Factor judge Simon Cowell organised the track.

I was thinking at the time, raise some money, I also

thought raise awareness, and I also thought

raise some support.

I wanted it to be something that, you know, weeks, months later,

when you hear the record, you still remember what happened.

To the boys at a school in Exeter now who've decided to protest

about their strict uniform policy in skirts!

Confused?

Here's Ayshah...

Just another normal day walking into school, but wait,

are the boys wearing...

Skirts?

Yep, they certainly are.

But why?

Well, the during the recent heatwave, the boys complained

that they weren't allowed to wear shorts.

Then a teacher jokingly said, "Well, you could wear skirts."

Well, because five people did it yesterday, so then everyone was,

like, if everyone else does it, then they can't stop

anyone else doing it, so then they might bring shorts back

for the summer.

Girls are allowed to wear skirts all year round,

they get cold legs and we have to sit there sweating.

I think it's good.

If they can't wear shorts, then they have to wear skirts.

The school said, with hot weather becoming more normal,

they might consider a change in the future, but the protesters

didn't count on one thing - the heatwave is over.

And what could be the biggest ship in the world has docked

in the UK for the first time.

Dozens of people headed out to Felixstowe, Suffolk,

to watch it arrive all the way from Shanghai, China.

She stands at 194 foot tall, about four times the size

of Big Ben in London.

Next - to something that looks like it's from out of this world.

Algae, that glows in the dark.

Here's Ricky to explain why.

It's a rare sight, the ocean glowing in the dark.

Yeah, a couple of salmon at the back jumping out.

It was like fireworks sort of thing, the water.

It was pretty cool.

What you're looking at is Noctiluca scintillansmore, also

known as sea sparkler.

When you pick it up, it dribbles through your fingers.

Whenever it lands on something, it glows.

Just little splatters of bright blue, I suppose.

The glow is caused by a natural chemical reaction with algae.

When a boat drives through it or you put your hand through it,

the chemical reaction is initiated, as a result of which,

you get this emission of light.

Algae are tiny living things that are found in water all the world.

When the algae is touched, it changes colour from a dull pink

to a bright electric blue.

They are not observed as often in the colder waters off Australia

but more in the sub tropical and warm temperate waters.

This display was caught on camera at a beach in South Australia.

The glow is completely harmless, but what a sight!

It's getting closer to your summer holidays.

But when it comes to the destination, do you prefer

to visit the same place each year or go somewhere new?

Well, psychologist Oliver James says it's better for children

to go to the same place, because it's nice to know

you are going to a familiar place.

We asked what you think.

It's best if you travel when you're younger and when you're older.

I like going to the same place every year.

I think it is nice to go somewhere new after a bit,

but it's just relaxing to go to the same place and do

the same things often.

I personally like going different places, because it's good

to get new experiences.

Online, you've also been having your say about this.

That's all from me, Newsround's back from 07.40 tomorrow morning.

Yo, whassup? Do you watch CBBC shows on your phone or tablet?

Oh, wait.
