:00:00. > :00:00.Hey, everyone, Leah here with today's Newsround.
:00:00. > :00:11.We meet the scientists checking air pollution from the sky.
:00:12. > :00:15.How cool is it being a world champion surfer?
:00:16. > :00:29.And oven gloves at the ready - tonight's the final of Bake Off!
:00:30. > :00:31.But first, it's here tonight, it's the final
:00:32. > :00:34.of The Great British Bake Off and with this year's Royal Theme,
:00:35. > :00:38.Candice, Andrew and Jane will be getting their best whisking spoons
:00:39. > :00:45.So joining me on the sofa now is last year's Junior Bake Off winner
:00:46. > :00:54.Amari to give us her thoughts on the final.
:00:55. > :01:05.first of all, who do you think will win? I am jumping between Candace
:01:06. > :01:10.and Jane. They are all good bakers, but it will be one of them. What do
:01:11. > :01:17.you have to do to become champion Becker? You have to be a good break
:01:18. > :01:22.out, but it is also the personality and your creative skills to go with
:01:23. > :01:31.it as well. If you do not have that, I don't think it will win. So much
:01:32. > :01:35.goes into it. Overall, looking at the series, who has been the
:01:36. > :01:37.standout personality or the contestant you enjoy watching the
:01:38. > :02:09.most? And what makes them so good? You
:02:10. > :02:16.just need to keep calm. With him being so calm, he got to the
:02:17. > :02:20.semifinals. I have learnt a few tips about baking and I would like to try
:02:21. > :02:23.and make what they have made. Thank you so much. Brilliant having you
:02:24. > :02:26.here. You can head online for loads more
:02:27. > :02:29.good stuff about Bake Off, including We also want to know who you think

:02:37. > :02:39.of your comments later on. Now, when it comes to pollution
:02:40. > :02:42.you might think of things down here on the ground like car fumes
:02:43. > :02:45.and factories, but to find out more about how clean the air
:02:46. > :02:47.in our cities actually is, This is one of the most advanced
:02:48. > :02:56.scientific aircraft in the world. It is this plane's job to measure
:02:57. > :02:59.the amount of air pollution there is in cities across the UK
:03:00. > :03:02.and I'm about to hop on board from East Midlands to Manchester
:03:03. > :03:08.to see how it works. On the outside it might look
:03:09. > :03:13.like an ordinary aeroplane, but on the inside it is
:03:14. > :03:20.a high-tech chemistry lab. On board I spoke to one of the lead
:03:21. > :03:25.scientists to find out more. James, what are we doing
:03:26. > :03:28.on this aircraft today? We are flying off the coast
:03:29. > :03:32.of Liverpool and Manchester. The wind is currently blowing
:03:33. > :03:37.all the pollution that gets emitted from cars and factories and things,
:03:38. > :03:41.it is blowing it over the sea and we are crossing that plume
:03:42. > :03:43.of pollution trying to measure how What we are doing here is trying
:03:44. > :03:52.to understand better where this pollution is coming from,
:03:53. > :03:55.how much is being emitted and then going forward how to better inform
:03:56. > :04:01.people as to how we can improve James, how unique is this aircraft
:04:02. > :04:10.in what it does? It is the largest one in Europe
:04:11. > :04:17.and it is pretty much Compared to other aircraft
:04:18. > :04:24.around the world it is We have got a few bits of equipment
:04:25. > :04:29.out hanging beneath the wings that measure things like clouds as we go
:04:30. > :04:32.through them and we have also got quite a lot of equipment
:04:33. > :04:34.inside the aircraft cabin. The air is being sucked
:04:35. > :04:36.through and our instruments are providing a measurement
:04:37. > :04:38.of the different air pollutants. There is a lot of high-tech
:04:39. > :04:42.equipment being flown around The leaves are brown outside so that
:04:43. > :04:50.can mean only one thing - The show's team are in Dorset
:04:51. > :04:54.all week, in the south of England, and here are the presenters to tell
:04:55. > :04:57.you what they're up to. Yes, we are back and this year
:04:58. > :05:01.we are at the RSPB reserve at Arne in Dorset which is a fabulous place
:05:02. > :05:05.to be at this time of the year. One of the amazing sights
:05:06. > :05:08.is all the birds that arrive, the migrating waders, that come
:05:09. > :05:12.to overwinter on the wetlands. We have got deer fighting
:05:13. > :05:20.and calling in the night. We have seen foxes, badgers,
:05:21. > :05:23.rabbits, mice, everything. And if you get out and about this
:05:24. > :05:27.time of year you might find one of these because the deer
:05:28. > :05:29.shed their antlers. So enjoy Autumn Watch and get out
:05:30. > :05:36.there and enjoy autumn. And finally to one of the biggest
:05:37. > :05:39.surfing competitions ever. It's held in portugal and top surfer
:05:40. > :05:42.John-John Florence is officially the best after wining the 2016 World
:05:43. > :05:45.Championship. The tournament hasn't even finished
:05:46. > :05:49.but John has so many points That's all from me, Newsround's back
