0:00:03 > 0:00:05Morning, guys.
0:00:05 > 0:00:07It's Tuesday, I'm Ricky and this is Newsround.
0:00:07 > 0:00:12Here's what's coming up:
0:00:12 > 0:00:14Closing the road for a proper playtime.
0:00:14 > 0:00:22And how much food does a dolphin need to eat?
0:00:27 > 0:00:30First up, a story of how community spirit and playing in the street has
0:00:30 > 0:00:33helped a girl with autism make friends for life.
0:00:33 > 0:00:36Hayley's got this one.
0:00:36 > 0:00:39This street in Bristol in south-west England kicks out cars once a week
0:00:39 > 0:00:41so that children can play more freely.
0:00:41 > 0:00:44The scheme is called Playing Out and has had a big impact
0:00:44 > 0:00:46on these kids' lives.
0:00:46 > 0:00:48We've made lots of friends in the street.
0:00:48 > 0:00:53Well, it's really fun and you get to do lots of activities.
0:00:53 > 0:00:56It's also a place where Poppy has been able to make new friends.
0:00:56 > 0:00:59I don't go to school, I'm hospital education.
0:00:59 > 0:01:01So that's basically the same as home educated,
0:01:01 > 0:01:06but my friends still go to school.
0:01:06 > 0:01:09Poppy was born with autism, which is a condition that can affect
0:01:09 > 0:01:12the way you live your life and see the world around you.
0:01:12 > 0:01:14Poppy was at a school, but because of her anxiety
0:01:14 > 0:01:16linked to her autism, that was too overwhelming
0:01:16 > 0:01:17and she was becoming very unwell.
0:01:17 > 0:01:20So now she stays at home and has a tutor come
0:01:20 > 0:01:23to the house, which is sent by the hospital education service.
0:01:23 > 0:01:26So for her playing out with other children is more of a rarity.
0:01:26 > 0:01:29Most streets, she is too frightened to walk down because of the noise.
0:01:29 > 0:01:31Yet you'll see her in this street feeling completely happy,
0:01:31 > 0:01:37playing with all the children.
0:01:37 > 0:01:39It's just so valuable to us as a family.
0:01:39 > 0:01:42If I didn't do Playing Out, I probably wouldn't have met someone
0:01:42 > 0:01:43else who is home educated like me.
0:01:43 > 0:01:51She's called Imelda May and we're best friends.
0:01:52 > 0:01:54And if you want to know more about autism, or to get
0:01:54 > 0:01:57some info about anxiety, you can find loads of information
0:01:57 > 0:02:00and advice over at Newsround Online where you can also watch our
0:02:00 > 0:02:03two special programmes.
0:02:03 > 0:02:06Next - if we don't eat enough, we run out of energy
0:02:06 > 0:02:07pretty quickly, right?
0:02:07 > 0:02:09That's because all of us use energy from food, called calories,
0:02:09 > 0:02:12to keep us on the move.
0:02:12 > 0:02:15And if you think you've got a plateful, you should see how much
0:02:15 > 0:02:19dolphins need to munch.
0:02:19 > 0:02:20Felling peckish?
0:02:20 > 0:02:23If you have had an active day, you might find your tummy rumbling.
0:02:23 > 0:02:26But well kids like you are recommended to munch around
0:02:26 > 0:02:291500 calories each day.
0:02:29 > 0:02:34You will never guess how much dolphins need to eat.
0:02:34 > 0:02:37New research has found that our flippered friends need up
0:02:37 > 0:02:38to a whopping 33,000 calories a day!
0:02:38 > 0:02:43Wow!
0:02:43 > 0:02:45That's 60 plates of salmon to me and you, and amazingly,
0:02:45 > 0:02:47that amount was less than scientists expected.
0:02:47 > 0:02:50The amount of food a dolphin needs varies depending on its size
0:02:50 > 0:02:52and whether it's resting, sleeping, diving or
0:02:52 > 0:02:58swimming, as well as the temperature of the ocean.
0:02:58 > 0:03:02Looks like this guy's working up an appetite.
0:03:02 > 0:03:06The study was carried out on common bottlenosed dolphins in Florida.
0:03:06 > 0:03:09They were captured for a short time in order to be monitored
0:03:09 > 0:03:13by scientists, who say the research will help with conservation.
0:03:13 > 0:03:18I just hope all that fish is providing enough vitamin C.
0:03:18 > 0:03:21Get it, because they're in the C, the sea...
0:03:21 > 0:03:24Never mind.
0:03:24 > 0:03:27Teenagers in Wales could be able to vote in some
0:03:27 > 0:03:28elections from the age of 16.
0:03:28 > 0:03:31The Welsh government says it wants to lower the age at which people
0:03:31 > 0:03:33can vote from 18 to 16 in local elections.
0:03:33 > 0:03:35In Scotland the voting age has already been
0:03:35 > 0:03:38lowered for some elections, but in the rest of the UK
0:03:38 > 0:03:40there are no plans to let 16 and 17-year-olds vote.
0:03:40 > 0:03:46These Welsh teenagers told us what they think of the idea.
0:03:46 > 0:03:50It will be a good thing for us to be able to vote because we would be
0:03:50 > 0:03:54voting for our future.
0:03:54 > 0:03:56Personally, I don't believe we should lower the age to 16
0:03:56 > 0:04:01because I don't feel that schools are educating us enough
0:04:01 > 0:04:03on the politics side of things.
0:04:03 > 0:04:05I'm in favour of voting at 16 because I think
0:04:05 > 0:04:08we are educated enough at 16 years old because we use social media.
0:04:08 > 0:04:10We see the parties, the advertisements
0:04:10 > 0:04:18they put out out there.
0:04:18 > 0:04:20It would probably raise a lot of interest within the 16,
0:04:20 > 0:04:2317-year-olds, but at the same time I feel like a lot of students
0:04:23 > 0:04:26who are 16, 17 will take the vote for granted.
0:04:26 > 0:04:30They'd just sort of vote for whoever their mates are voting for.
0:04:30 > 0:04:33If I use my voice I can change my future, so I think I would.
0:04:33 > 0:04:35It's really important for everyone to vote
0:04:35 > 0:04:38if they have the chance to, and I think maybe if we did
0:04:38 > 0:04:41have the right to vote, it would be more appealing
0:04:41 > 0:04:44for our age group to vote.
0:04:44 > 0:04:49That's it from me.
0:04:49 > 0:04:57I'll be back in about half-an-hour.
