:00:23. > :00:27.Hi guys. It's girl power on Newsround this afternoon. Hayley
:00:27. > :00:32.and Nel here with all the day's top stories. Here's what's coming up.
:00:32. > :00:35.Switch off, or standby? We've been on an energy saving challenge. And
:00:35. > :00:41.it's my most dangerous mission yet for Newsround - swimming with
:00:41. > :00:45.sharks! But first to Northern Ireland, where the Queen's started
:00:45. > :00:48.a two-day visit as part of her Diamond Jubilee celebrations. But
:00:48. > :00:51.this trip is very different from the other parts of her Jubilee tour.
:00:51. > :00:54.That's because over the years there's been a lot of violence
:00:54. > :00:58.there, as people are divided about whether to stay part of the UK or
:00:58. > :01:01.join the Republic of Ireland. This visit is one of the first in 40
:01:01. > :01:04.years by the Queen, that hasn't been kept a secret and many hope it
:01:04. > :01:14.will show just how far the peace process in Northern Ireland has
:01:14. > :01:15.
:01:15. > :01:20.come. This visit isn't about the past. How can you forget the past,
:01:20. > :01:26.but no-one will. It's about the future. The good thing about this
:01:26. > :01:30.crowd, people here, five, six, seven, eight, nine years of age.
:01:30. > :01:35.They've only known the good days in Northern Ireland. We don't have
:01:35. > :01:42.total peace yet, but dare I say it, this looks like a scene you could
:01:42. > :01:44.see in most parts of the UK today. Crowds have lined the streets and
:01:44. > :01:47.Union flags are everywhere to be seen. The Queen has visited
:01:47. > :01:51.Northern Ireland 19 times during her reign, but she hasn't always
:01:52. > :01:56.been made to feel this welcome. For years, violent clashes there
:01:56. > :01:59.between two main groups of people, have led to a lot of problems.
:01:59. > :02:03.Unionists wanted Northern Ireland to stay part of the UK and be ruled
:02:03. > :02:08.by the Royal Family. Nationalists wanted the area to join the rest of
:02:08. > :02:12.Ireland, the Republic. For years, armed groups on both sides held
:02:12. > :02:15.violent campaigns. There were bomb attacks in Northern Ireland and in
:02:15. > :02:19.Britain. Many people died in the conflict which became known as The
:02:19. > :02:25.Troubles. All this made it a very dangerous place for the Queen to
:02:25. > :02:28.visit. For years details of her visits were kept top secret. In her
:02:28. > :02:38.Silver Jubilee, she couldn't stay overnight, and no one was allowed
:02:38. > :02:39.
:02:39. > :02:42.to know where and when she was arriving. Earlier on, the Queen
:02:42. > :02:46.arrived by helicopter to a church in Enniskillen, a town where 12
:02:46. > :02:49.people were killed by a bomb during the height of the violence. And
:02:49. > :02:51.lots of eyes will be on her tomorrow when she'll meet Martin
:02:51. > :02:53.McGuinness, the former leader of a terrorist group called the
:02:53. > :02:57.Provisional IRA, who were responsible for that attack and
:02:57. > :03:01.another which killed Prince Philip's uncle. He's now Northern
:03:01. > :03:04.Ireland's Deputy First Minister. Despite the celebrations taking
:03:04. > :03:09.place in many parts of the country, there have still been some protests
:03:09. > :03:12.by people unhappy at the Queen's visit. On the whole though this is
:03:12. > :03:18.seen as a ground-breaking trip that is hoped will mark the start of a
:03:18. > :03:21.new Northern Ireland. Now to a massive stroke of luck for two guys
:03:21. > :03:25.in Jersey and their metal detectors. They've found one of Europe's
:03:25. > :03:30.largest ever hoards of old coins. They're more than 2,000 years old
:03:30. > :03:35.and thought to be worth around �10 million. Archaeologists say there
:03:35. > :03:41.could be about 50,000 in all. It'll take months to sort through them
:03:41. > :03:46.properly. Now, you've been on the Newsround website today, telling us
:03:46. > :03:49.how you save energy. It's after a report found that by leaving things
:03:49. > :03:53.like TVs and mobiles on standby instead of switching them off, we
:03:53. > :04:00.waste enough energy in a year to run two power stations for 12 whole
:04:00. > :04:03.months! Your comments in a sec guys, first though, watch this. You get
:04:03. > :04:07.home from a long day at school, kick off your shoes, turn on the tv,
:04:07. > :04:17.maybe you're laptop too and text your mates on your phone while it's
:04:17. > :04:35.
:04:35. > :04:41.charging. But when you're done, do you actually turn them off? Knell!
:04:41. > :04:45.Nell! As a country we're now using a lot more energy than before, but
:04:45. > :04:48.what makes it worse is that a lot of it is wasted. It's because lots
:04:48. > :04:51.of us aren't turning off stuff tvs and laptops properly, but just
:04:51. > :04:54.leaving them plugged in or on sleep mode. Lots of people reckon that
:04:54. > :04:57.leaving stuff on standby or sleep mode means that it stops using
:04:57. > :04:59.electricity, but it doesn't. Some experts reckoned that the amount of
:04:59. > :05:03.electricity wasted by leaving gadgets in standby or sleep mode
:05:03. > :05:06.would be enough to keep two power stations going for a year. Things
:05:06. > :05:08.like not unplugging your mobile or laptop when its fully charged waste
:05:08. > :05:11.electricity. And overcharging some gadgets like smart phones can
:05:11. > :05:15.actually damage their battery life in the long run. A group that looks
:05:15. > :05:18.into how we can save more energy say that the amount of energy each
:05:18. > :05:21.family wastes by leaving stuff on standby is the same amount needed
:05:21. > :05:31.to power their tv, DVD player, set- top box, hi-fi and radio for 12
:05:31. > :05:33.
:05:33. > :05:36.months. Over the next few years it's going to become harder to
:05:36. > :05:40.power Britain, so the Energy Savings Trust want to work with the
:05:40. > :05:43.Government to make us more energy smart. On the Newsround website,
:05:43. > :05:46.Maika from Bognor Regis says, "My family and I save electricity by
:05:46. > :05:49.not using too many lights and remembering to turn them off. Not
:05:49. > :05:53.only does it save energy it saves money." And Abby got in touch all
:05:53. > :05:56.the way from Hong Kong. She's got a top tip. "My family have reminder
:05:56. > :06:00.notes on everything so when you leave a device on, you see the
:06:00. > :06:02.reminder and you remember to switch it off." Last word from Kaleb in
:06:02. > :06:12.Merseyside who says, "The way I save electricity is instead of
:06:12. > :06:15.watching TV, I read for two hours." Hope you're watching now, Kaleb.
:06:15. > :06:18.Someone who'll be wanting to save up all his energy is Andy Murray,
:06:18. > :06:23.who's making his first Wimbledon appearance of the year a bit later
:06:23. > :06:27.on. Could be a tough match. He'll play the former world number three
:06:28. > :06:37.Nikolay Davydenko from Russia. Former Wimbledon champion, Rafa
:06:38. > :06:39.
:06:39. > :06:43.Nadal, is playing now on Centre Court. He's two sets up against
:06:43. > :06:46.Thomaz Bellucci. I've done some pretty daring stuff for Newsround.
:06:46. > :06:50.I've rescued lions and been pulled on a sledge by husky dogs. But
:06:50. > :06:54.nothing quite beats swimming with sharks. I'm so jealous. It wasn't
:06:55. > :07:04.just for fun though.. Hayley was on a mission to find sharks teeth to
:07:05. > :07:06.
:07:07. > :07:11.see what they tell us about ancient breeds of the species. This is
:07:11. > :07:16.Blackpool Sea Life Centre and there are five different species of
:07:16. > :07:20.sharks, including this eight-foot large one and in a few moments I'll
:07:20. > :07:23.be getting in there to collect their teeth. Experts here are
:07:23. > :07:27.working with the University of Birmingham to find out more about
:07:27. > :07:31.sharks that lived thousands of years ago, by collecting their
:07:31. > :07:36.teeth and today I'm giving them a helping hand. Here we go. To do
:07:36. > :07:42.that, I've got to get in at the deep end. The tank is ten-feet deep
:07:42. > :07:46.and with 15 sharks in there, one nearly nine-foot long, well, I was
:07:46. > :07:52.nervous, but I didn't have to go near their mouths. They lose their
:07:52. > :07:56.teeth naturally, so I just collect them. There you go. It was quite
:07:56. > :07:59.scary, but I've managed to find some shark teeth and I'm glad to be
:08:00. > :08:04.getting out of here. This is one of the teeth I've collected today.
:08:04. > :08:09.What sort of information can this tell you? We look at the chemistry
:08:09. > :08:12.and it can reflect the food and nutrition which sharks take. This
:08:12. > :08:15.is a prehistoric tooth and if you compare that one to the one I've
:08:15. > :08:20.got today you can find out the differences between the environment.
:08:20. > :08:25.Exactly. How warm the water was, what was the climate life millions
:08:25. > :08:28.of years ago. The tooth will hopefully help scientists get
:08:28. > :08:31.closer to sharks that were around thousands of years ago, but
:08:32. > :08:41.considering their had teeth this big, well, I think I got close
:08:42. > :08:46.
:08:46. > :08:54.enough today already. That's it. Look at this egg roulette. One
