:00:25. > :00:28.Afternoon everyone. Newsround has arrived on BBC One with Leah and
:00:28. > :00:33.Joe. We have another action-packed show, and here's the proof:
:00:33. > :00:36.We find out what's powering the fastest thing ever on four wheels.
:00:36. > :00:42.And we carry on Space Week by cranking up the heat on the biggest
:00:42. > :00:45.star in our universe. First up we're talking school
:00:45. > :00:48.dinners. A few years ago, the celebrity chef, Jamie Oliver,
:00:48. > :00:51.started a big campaign to try to make them more healthy, but there
:00:51. > :00:54.are worries they're still not as good as they should be. Now, the
:00:54. > :00:59.Government is sending the people behind fast food health chain Leon
:00:59. > :01:02.to schools to check if you guys are getting the right things for lunch.
:01:02. > :01:04.Hayley's been to a school that's undergone a revolution in healthy
:01:04. > :01:08.cooking since the summer, with salads, fruit and all sorts of
:01:08. > :01:16.other good stuff on the menu. But it doesn't mean they still can't
:01:16. > :01:22.enjoy the odd treat. It is lunchtime here at this primary
:01:22. > :01:28.school in North London. On the menu today we've got burgers chips and
:01:28. > :01:34.beans, vegetable pasty, jelly or fruit. Most of the kids today have
:01:34. > :01:39.gone for burgers and chips, but it's a Friday. What have you had
:01:39. > :01:45.for dinner today? Burger and chips. I had chips, a burger and some
:01:45. > :01:48.beans. How was it? Really nice. There are figures out there,
:01:48. > :01:54.according to Government figures just under half of kids each one
:01:54. > :01:59.portion of fruit a day but over half of schoolchildren eat some
:01:59. > :02:03.fried or cooked food like pizzas and burgers every day. It is up to
:02:03. > :02:10.this guy to do something about that. This is John, the man from Leon,
:02:10. > :02:15.who is on a mission to make meals happier. We've been forced into a
:02:15. > :02:20.position of creating I guess a plan for how we can get more kids eating
:02:20. > :02:24.great food. The other thing is to try to make school food exciting
:02:24. > :02:31.for kids. Make sure they don't have to queue for long and that the
:02:31. > :02:35.dining rooms are attractive. Jamie Oliver did this four years ago, why
:02:35. > :02:40.are you having to do this again? Jamie publicised some of the
:02:40. > :02:45.problems out there and started to make people realise that it is
:02:45. > :02:49.possible for kids to eat better. What we now need to do is take it
:02:49. > :02:53.from where it is, which is better than it was and make it better
:02:53. > :02:57.again. Many people are saying you are not going to do anything with
:02:57. > :03:02.it, what are you going to do? make a good point. We don't want to
:03:02. > :03:06.delay anything. We want to make it better straight away. Over the next
:03:06. > :03:10.year John promises to keep news the loop. On Newsround we hear that
:03:10. > :03:15.kids care a lot about the food they eat at school. Would you be able to
:03:15. > :03:18.keep us up to date with your findings and your action plan over
:03:18. > :03:22.the next year? We would be delighted to do that. It's a big
:03:22. > :03:25.part of what we hope to do. Well, we want to hear what you
:03:25. > :03:28.think of your school dinners. Do you want healthier options, or
:03:28. > :03:38.would you be upset if things like chips were taken off the menu
:03:38. > :03:45.
:03:45. > :03:48.completely? Loads of you have been Next up, we're halfway through our
:03:48. > :03:50.special space week on Newsround, where we're finding out about the
:03:50. > :03:53.most interesting stories in the universe. Today we're talking about
:03:53. > :03:56.the one thing we most definitely couldn't live without - the Sun.
:03:56. > :03:59.It's going through some massive changes, so I've been to meet the
:03:59. > :04:09.people trying to understand what's happening, and predict what it'll
:04:09. > :04:13.
:04:13. > :04:17.mean for all of us in future. Our Sun, a huge chemical factory
:04:17. > :04:22.burning at 15 million degrees Celsius. It is 93 million miles
:04:22. > :04:29.away, but without it we wouldn't be here. For our an c'est overs it was
:04:29. > :04:32.seen as a God, bringing light and warmth to Earth. Even today people
:04:32. > :04:37.travel to Stonehenge in Wiltshire to worship the star. Our
:04:38. > :04:42.understanding of the Sun has progressed thanks to NASA's
:04:42. > :04:45.observatory. But at the moment something's happening to our star
:04:45. > :04:51.and scientisting like Liz have noticed big changes. Tfrplgts Sun
:04:51. > :04:55.has an 11-year cycle. Every 11 years it gets a lot more active.
:04:55. > :05:01.There'll be a lot more sunspots. These are a sign that the Sun is
:05:01. > :05:06.moving around a lot more. It throws out huge amounts of particles. They
:05:06. > :05:10.can damage satellites. They can affect computers and power lines.
:05:10. > :05:15.They can stop your television transmission. Predicting and
:05:15. > :05:19.preparing for these events is really important. That in mind the
:05:19. > :05:24.European Space Agency are in the middle of their most daring noigs
:05:24. > :05:29.the Sun yet. The solar orbiter be launched in 2017. It will cost
:05:29. > :05:35.hundreds of millions of pounds but get scientists closer to the star
:05:35. > :05:42.than ever before. Surely it is going to melt? The top of the heat
:05:42. > :05:49.shield are get to over 1,200 degrees Celsius. That's twice as
:05:49. > :05:53.hot as an oven. A maximum of 50 degrees assessies. And that will
:05:53. > :05:59.protect the electronics become there? Yes it will. Some cameras
:05:59. > :06:03.will look at the surface of the Sun. Others will concentrate on the
:06:03. > :06:07.atmosphere and a couple will look at the extended atmosphere. The Sun
:06:07. > :06:11.will continue to burn for 5 billion years ago. There are lots of
:06:11. > :06:18.unanswered questions about how it affects Earth, but most of us will
:06:18. > :06:23.carry on enjoying it regardless. The Sun is one of which 200 billion
:06:23. > :06:27.that make up our galaxy. It is nice to think that somewhere out there
:06:27. > :06:30.is one just starting its cycle. And don't forget to tell us what
:06:30. > :06:33.area of space you think we should be exploring next over on the
:06:33. > :06:36.Newsround website. We'll be revealing the results of our big
:06:36. > :06:39.space survey on Friday. Next, it's a big day for fast cars.
:06:39. > :06:42.And we're talking really fast cars. Bloodhound is a rocket-powered car.
:06:42. > :06:46.The British team behind it say it's faster than a bullet. They've
:06:46. > :06:49.designed it to reach speeds of more than 1,000 miles per hour - enough
:06:49. > :06:53.to break the land speed record by 2014. And today they're giving it a
:06:53. > :06:56.test drive for the first time. Nel went to meet the engineers who
:06:56. > :07:02.created it. If successful, this is what the first car to reach 1,000
:07:02. > :07:06.miles per hour will look like. The guys behind the Bloodhound are
:07:06. > :07:10.confident that it is fast. This car is faster than a bullet. Will it be
:07:10. > :07:14.the fastest horizontal thing that has a man in it. It breaks the
:07:14. > :07:17.airspeed record as well as the land speed record. That record was
:07:18. > :07:22.broken three years ago in North America. This is going 300 miles
:07:22. > :07:25.per hour faster than Thruster went. This will be unbelievable. On
:07:25. > :07:31.Wednesday what we are doing for the first time is firing the rocket
:07:31. > :07:36.system in one go. We are using pumped liquid into the rocket.
:07:36. > :07:39.That's amazing in itself. Bloodhound has the same engine as a
:07:39. > :07:43.jet fighter. Will it be driven bay pilot and will look like kit fly to
:07:43. > :07:46.the Moon. But keeping it on the ground is one of the biggest
:07:46. > :07:49.challenges. You have to try and stop the car from flying, which is
:07:49. > :07:55.never a good thing. It has four wheels all in contact with the
:07:55. > :07:59.ground. They must stay in contact to get a record, let alone keeping
:07:59. > :08:03.our drivers safe. The attempt to hit the 1,000 miles per hour mark
:08:03. > :08:06.won't happen until late next year, something everyone is only too
:08:06. > :08:11.aware of. I'm sure we've got the best car but competition is what
:08:11. > :08:14.makes this exciting. We've got four other credible computers. Two
:08:14. > :08:18.American, one Australian and one from New Zealand. We want to get
:08:18. > :08:24.the record for Britain. To do that the engine needs to work perfectly.
:08:24. > :08:27.That's why today's testing is such a big deal.
:08:27. > :08:30.Would you like to drive that? would be terrified.
:08:30. > :08:34.Finally, ever wondered what happens when you flush the loo? A water
:08:34. > :08:37.company in Poland has created an app that lets people in one town
:08:37. > :08:40.follow the passage of their poo! They say users can even compare the
:08:40. > :08:43.speeds at which it travels through sewers. It's supposed to get young
:08:43. > :08:47.people interested in the sewage systems. I'm not sure it's going to
