Good morning.

I'm Jenny, live with all the news you need to know this Thursday.

Here's what's coming up...

The smoky fog that's choking some of China's big cities.

A new campaign to get more kids into science.

And Chelsea's mega unbeaten run comes to an end against Spurs.

First up, the person whose job it is to speak up

for kids in England, called the Children's Commissioner,

says you need more advice about staying safe online.

She says lessons should start when kids are four and the rules

of apps should be clearer when you sign up.

But do you agree?

The Commissioner told Newsround what she thinks should happen.

Well, I want to see lessons in every school.

We want to put together all the children in secondary

schools with younger children to lead those lessons and make sure

children learn things that they need to know about their time online.

You should have an independent person who you can go to if things

go wrong online and they can help sort out those difficulties.

So what do you think about the idea of lessons in schools?

We asked these children.

When you're older, you do need them to stay safe as you know a lot

more about social media, how to log on.

When you're younger, you might forget a lot

and not really know.

So there's no real point wasting time on it.

When you are in primary, it is never about that.

It is just about what game you're playing or something.

I know that most kids, they don't read the terms and conditions.

So, I think the terms and conditions and the important stuff that

you need to know about setting up a profile, they need to be more

talked about and kids need to be told about privacy settings.

Rules need to be short and snappy, like one, two, three, not 15 pages.

In lessons, I would like to find out more about how children are put

in a position to be bullied and how we can prevent that.

So, by reading shorter terms and conditions and by going on sites

that you should be allowed on and not other ones.

We want to know what you think about this.

Should all kids get lessons about sharing safely online?

Do you need more information about what you are signing up

to when you use social media apps?

The Chinese capital of Beijing is on red alert because a thick

blanket of pollution, called smog, has been covering

the city for the last week.

It's been causing all sorts of problems.

Martin's got this one.

It could so easily be mistaken for a winter mist,

slowly creeping around the buildings and down the streets of Beijing.

But the people living there know better.

Over the last week, northern parts of China,

including the capital, Beijing, have been badly affected

by high levels of air pollution, which is referred to as smog.

This means that the air has become so polluted that the particles

in it can actually be seen and it looks like a smoky fog,

hence the word "smog".

It can be caused by factories burning lots of coal and exhaust

from high levels of traffic.

The weather also plays a major part, and if there is not much wind,

polluted air can gather and stay in one place for a long time.

Beijing is particularly bad at this time of year as the cold

temperatures mean the factories to the south of the city burn more

coal to keep people warm.

Smog can cause health problems by making it difficult to breathe,

irritating the eyes and nose and making it harder

for the body to fight infections and illnesses properly.

It has a huge impact on people's lives.

People have to take precautions if they leave their house,

such as wearing facemasks.

In some cases, schools have to be closed and kids

are made to stay inside.

Hundreds of flights have had to be cancelled and roads shut

because of low visibility.

Factories have also been closed to stop the situation getting worse.

China's government says that it is working hard to reduce

the amount of pollution in the air.

But, for now, it is hoped that the winds predicted for the end

of the week will clear the air and blow the smog away.

Footie now, and Chelsea's incredible winning streak is over

after they were beaten 2-0 by Tottenham Hotspur

at White Hart Lane.

Two goals from Dele Alli ended Chelsea's run of 13 consecutive wins

and moves Spurs up to third.

And from goals to golds...

Double Paralympic champion Kadeena Cox is having the money

she gets from UK Sport stopped after she said she was

going on the Channel 4 programme, The Jump.

UK Sport say she will get it back when she starts training again.

Kadeena says having the condition multiple sclerosis has

changed her outlook, and she's looking forward

to enjoying the skiing.

What's your favourite subject at school?

Only 15% of you say you would like to be

scientists when you grow up, so now a new project has been set up

called Terrific Scientific.

The campaign hopes to bring science skills into the classroom by getting

kids to do investigations that will help with real

scientific studies.

Scientist Liz Bonnin thinks that the way we think

about science needs to change.

For some strange reason, science still has a lot

of stereotypes attached to it - ie, you've got to be

brainy to like science, or you have to work in a lab,

be an older gentleman with glasses and be extremely boring.

And it couldn't be further from the truth.

That's all from us for now.

Newsround's back right here at 4.20pm.

Don't forget to head online to tell us what you think would help kids

handle the online world better.

Have a brilliant day!
