0:00:05 > 0:00:06Good morning.
0:00:06 > 0:00:09I'm Jenny, live with all the news you need to know this Thursday.
0:00:09 > 0:00:11Here's what's coming up...
0:00:11 > 0:00:15The smoky fog that's choking some of China's big cities.
0:00:15 > 0:00:18A new campaign to get more kids into science.
0:00:18 > 0:00:22And Chelsea's mega unbeaten run comes to an end against Spurs.
0:00:35 > 0:00:38First up, the person whose job it is to speak up
0:00:38 > 0:00:40for kids in England, called the Children's Commissioner,
0:00:40 > 0:00:42says you need more advice about staying safe online.
0:00:42 > 0:00:45She says lessons should start when kids are four and the rules
0:00:45 > 0:00:47of apps should be clearer when you sign up.
0:00:47 > 0:00:48But do you agree?
0:00:48 > 0:00:55The Commissioner told Newsround what she thinks should happen.
0:00:55 > 0:00:57Well, I want to see lessons in every school.
0:00:57 > 0:01:00We want to put together all the children in secondary
0:01:00 > 0:01:03schools with younger children to lead those lessons and make sure
0:01:03 > 0:01:08children learn things that they need to know about their time online.
0:01:08 > 0:01:11You should have an independent person who you can go to if things
0:01:11 > 0:01:21go wrong online and they can help sort out those difficulties.
0:01:21 > 0:01:24So what do you think about the idea of lessons in schools?
0:01:24 > 0:01:27We asked these children.
0:01:27 > 0:01:31When you're older, you do need them to stay safe as you know a lot
0:01:31 > 0:01:33more about social media, how to log on.
0:01:33 > 0:01:35When you're younger, you might forget a lot
0:01:35 > 0:01:36and not really know.
0:01:36 > 0:01:38So there's no real point wasting time on it.
0:01:38 > 0:01:40When you are in primary, it is never about that.
0:01:40 > 0:01:44It is just about what game you're playing or something.
0:01:44 > 0:01:51I know that most kids, they don't read the terms and conditions.
0:01:51 > 0:01:53So, I think the terms and conditions and the important stuff that
0:01:53 > 0:01:58you need to know about setting up a profile, they need to be more
0:01:58 > 0:02:01talked about and kids need to be told about privacy settings.
0:02:01 > 0:02:08Rules need to be short and snappy, like one, two, three, not 15 pages.
0:02:08 > 0:02:14In lessons, I would like to find out more about how children are put
0:02:14 > 0:02:17in a position to be bullied and how we can prevent that.
0:02:17 > 0:02:20So, by reading shorter terms and conditions and by going on sites
0:02:20 > 0:02:24that you should be allowed on and not other ones.
0:02:24 > 0:02:27We want to know what you think about this.
0:02:27 > 0:02:30Should all kids get lessons about sharing safely online?
0:02:30 > 0:02:33Do you need more information about what you are signing up
0:02:33 > 0:02:35to when you use social media apps?
0:02:35 > 0:02:40Get to Newsround online and have your say.
0:02:40 > 0:02:44The Chinese capital of Beijing is on red alert because a thick
0:02:45 > 0:02:47blanket of pollution, called smog, has been covering
0:02:47 > 0:02:49the city for the last week.
0:02:49 > 0:02:50It's been causing all sorts of problems.
0:02:50 > 0:02:51Martin's got this one.
0:02:51 > 0:02:57It could so easily be mistaken for a winter mist,
0:02:57 > 0:02:59slowly creeping around the buildings and down the streets of Beijing.
0:02:59 > 0:03:02But the people living there know better.
0:03:02 > 0:03:04Over the last week, northern parts of China,
0:03:04 > 0:03:08including the capital, Beijing, have been badly affected
0:03:08 > 0:03:12by high levels of air pollution, which is referred to as smog.
0:03:12 > 0:03:18This means that the air has become so polluted that the particles
0:03:18 > 0:03:21in it can actually be seen and it looks like a smoky fog,
0:03:21 > 0:03:23hence the word "smog".
0:03:23 > 0:03:26It can be caused by factories burning lots of coal and exhaust
0:03:26 > 0:03:30from high levels of traffic.
0:03:30 > 0:03:33The weather also plays a major part, and if there is not much wind,
0:03:33 > 0:03:36polluted air can gather and stay in one place for a long time.
0:03:36 > 0:03:39Beijing is particularly bad at this time of year as the cold
0:03:39 > 0:03:42temperatures mean the factories to the south of the city burn more
0:03:42 > 0:03:44coal to keep people warm.
0:03:44 > 0:03:48Smog can cause health problems by making it difficult to breathe,
0:03:48 > 0:03:51irritating the eyes and nose and making it harder
0:03:51 > 0:03:54for the body to fight infections and illnesses properly.
0:03:54 > 0:03:57It has a huge impact on people's lives.
0:03:57 > 0:04:00People have to take precautions if they leave their house,
0:04:00 > 0:04:03such as wearing facemasks.
0:04:03 > 0:04:05In some cases, schools have to be closed and kids
0:04:05 > 0:04:09are made to stay inside.
0:04:09 > 0:04:12Hundreds of flights have had to be cancelled and roads shut
0:04:12 > 0:04:13because of low visibility.
0:04:13 > 0:04:16Factories have also been closed to stop the situation getting worse.
0:04:16 > 0:04:18China's government says that it is working hard to reduce
0:04:18 > 0:04:20the amount of pollution in the air.
0:04:20 > 0:04:24But, for now, it is hoped that the winds predicted for the end
0:04:24 > 0:04:30of the week will clear the air and blow the smog away.
0:04:30 > 0:04:32Footie now, and Chelsea's incredible winning streak is over
0:04:32 > 0:04:34after they were beaten 2-0 by Tottenham Hotspur
0:04:34 > 0:04:38at White Hart Lane.
0:04:38 > 0:04:44Two goals from Dele Alli ended Chelsea's run of 13 consecutive wins
0:04:44 > 0:04:46and moves Spurs up to third.
0:04:46 > 0:04:47And from goals to golds...
0:04:47 > 0:04:49Double Paralympic champion Kadeena Cox is having the money
0:04:49 > 0:04:53she gets from UK Sport stopped after she said she was
0:04:53 > 0:04:57going on the Channel 4 programme, The Jump.
0:04:57 > 0:05:03UK Sport say she will get it back when she starts training again.
0:05:03 > 0:05:05Kadeena says having the condition multiple sclerosis has
0:05:05 > 0:05:07changed her outlook, and she's looking forward
0:05:07 > 0:05:08to enjoying the skiing.
0:05:08 > 0:05:09What's your favourite subject at school?
0:05:09 > 0:05:12Only 15% of you say you would like to be
0:05:12 > 0:05:15scientists when you grow up, so now a new project has been set up
0:05:15 > 0:05:17called Terrific Scientific.
0:05:17 > 0:05:21The campaign hopes to bring science skills into the classroom by getting
0:05:21 > 0:05:23kids to do investigations that will help with real
0:05:23 > 0:05:26scientific studies.
0:05:26 > 0:05:28Scientist Liz Bonnin thinks that the way we think
0:05:28 > 0:05:30about science needs to change.
0:05:30 > 0:05:32For some strange reason, science still has a lot
0:05:32 > 0:05:35of stereotypes attached to it - ie, you've got to be
0:05:35 > 0:05:38brainy to like science, or you have to work in a lab,
0:05:38 > 0:05:40be an older gentleman with glasses and be extremely boring.
0:05:40 > 0:05:46And it couldn't be further from the truth.
0:05:46 > 0:05:48That's all from us for now.
0:05:48 > 0:05:50Newsround's back right here at 4.20pm.
0:05:50 > 0:05:54Don't forget to head online to tell us what you think would help kids
0:05:54 > 0:05:55handle the online world better.
0:05:55 > 0:05:57Have a brilliant day!
