0:00:11 > 0:00:14Hi, I'm Martin - and welcome to Newsround.
0:00:14 > 0:00:17It's a hundred years since a massive change in the law meant some women
0:00:17 > 0:00:20were allowed to vote in this country for the very first time.
0:00:20 > 0:00:28And that was made possible by a few superheroes.
0:00:35 > 0:00:37These are two superheroes with two very different superpowers,
0:00:37 > 0:00:41both battling a grave injustice.
0:00:41 > 0:00:44The story starts way back in 1897...
0:00:44 > 0:00:45I say!
0:00:45 > 0:00:48..when the only people allowed to vote for their MPs in the UK
0:00:48 > 0:00:52were rich men and no women at all.
0:00:52 > 0:00:55Marvellous Millicent was angry about it.
0:00:55 > 0:00:59She set up a league of heroes known as the suffragists.
0:00:59 > 0:01:02They campaigned for women to get the votes and tried to get support
0:01:02 > 0:01:05from men in Parliament.
0:01:05 > 0:01:08But for Amazing Emmeline, this wasn't enough.
0:01:08 > 0:01:10She started a different group of heroes called
0:01:10 > 0:01:14the suffragettes in 1903.
0:01:14 > 0:01:19They felt that they had to go much further to bring about change.
0:01:19 > 0:01:23They chained themselves to railings, set buildings on fire
0:01:23 > 0:01:26and attacked policemen.
0:01:26 > 0:01:28Not everyone liked the suffragettes because of their tactics.
0:01:28 > 0:01:32But they definitely made an impact.
0:01:32 > 0:01:35And then in 1914, a great darkness fell upon the planet
0:01:35 > 0:01:38and World War I broke out.
0:01:38 > 0:01:40That meant that women took the place of men
0:01:40 > 0:01:43in lots of really important jobs, while the men fought
0:01:43 > 0:01:45on the battlefield.
0:01:45 > 0:01:53And because women made a huge difference to winning the war,
0:01:54 > 0:01:56it became impossible to keep ignoring demands to
0:01:56 > 0:01:57give them the vote.
0:01:57 > 0:01:59So in 1918, the rules were changed.
0:01:59 > 0:02:02All adult men were allowed to vote, and for the first time, some women.
0:02:02 > 0:02:07It would be another ten years before all women could vote,
0:02:07 > 0:02:10but our superheroes played a huge part in creating a future where men
0:02:10 > 0:02:17and women could have an equal vote.
0:02:17 > 0:02:19Have you ever wondered what life's like from a polar
0:02:19 > 0:02:20bear's point of view?
0:02:20 > 0:02:27I know I have - and it seems so have scientists.
0:02:27 > 0:02:29So they attached small cameras to some
0:02:29 > 0:02:31of the bears to watch them going about their daily lives.
0:02:31 > 0:02:33Scientists say Arctic sea ice has been melting over
0:02:33 > 0:02:36the last few decades - but polar bears need that ice
0:02:36 > 0:02:41to help them catch their prey.
0:02:41 > 0:02:44They wanted to check if the animals got enough to eat.
0:02:44 > 0:02:47It's hoped the polar bear eye's view camera will help teach us more
0:02:47 > 0:02:51about how the animals are surviving.
0:02:51 > 0:02:54Next, it's one of the biggest sporting events in the world
0:02:54 > 0:02:56and the most important match in American football.
0:02:56 > 0:02:58I'm talking about the Super Bowl, which takes place this
0:02:58 > 0:03:01Sunday in the US.
0:03:01 > 0:03:03Ricky caught up with two experts to find out more
0:03:03 > 0:03:06about this incredible game.
0:03:14 > 0:03:15The Super Bowl is finally here.
0:03:15 > 0:03:19It is one of the biggest sporting events in the US and it's becoming
0:03:19 > 0:03:24huge all around the world and here in the UK too.
0:03:24 > 0:03:26It's one of the biggest sporting events in the world,
0:03:26 > 0:03:29not just the United States, and it's incredible.
0:03:29 > 0:03:31The United Kingdom taking to the sport is something
0:03:31 > 0:03:33we are all very excited about.
0:03:33 > 0:03:35The event is outstanding, the half-time show and everything
0:03:35 > 0:03:40involved with the game, I'm excited.
0:03:40 > 0:03:42A lot of people talk about the half-time show
0:03:42 > 0:03:45and there is always a huge celebrity on the stage.
0:03:45 > 0:03:46Who is it this year?
0:03:46 > 0:03:50Justin Timberlake.
0:03:50 > 0:03:55Can you tell us who is in the final and this year's Super Bowl?
0:03:55 > 0:03:58We have got the New England Patriots and the Philadelphia Eagles.
0:03:58 > 0:04:00The Philadelphia Eagles have never won a Super Bowl
0:04:00 > 0:04:02whereas the Patriots have won five.
0:04:02 > 0:04:04I'm leaning towards the Philadelphia Eagles right now,
0:04:04 > 0:04:07I like the way they play, but you can never really bet
0:04:07 > 0:04:08against New England Patriots.
0:04:08 > 0:04:11What about some top players to look out for?
0:04:11 > 0:04:14The top player in the history of the game, Tom Brady.
0:04:14 > 0:04:15Philadelphia, you've got the new quarterback
0:04:15 > 0:04:18Nick Foles who has really come into his own and last
0:04:18 > 0:04:19couple of games.
0:04:19 > 0:04:24We have Jay Ajayi, a British player, what do we think of him?
0:04:24 > 0:04:28He has been a spark.
0:04:28 > 0:04:30The reason they have had success of late
0:04:30 > 0:04:32is because of him and his skill set.
0:04:32 > 0:04:35Great player and fan favourite and I am excited to see him
0:04:35 > 0:04:36in the first Super Bowl.
0:04:36 > 0:04:39You've won the Super Bowl twice with the New York Giants.
0:04:39 > 0:04:40Tell us what that feeling was like.
0:04:40 > 0:04:43Hard to describe but I would equate it to winning the World Cup,
0:04:43 > 0:04:45something people here are more familiar with.
0:04:45 > 0:04:48It's so exciting, a lifelong dream, something of a kid America dreams
0:04:48 > 0:04:51about and to finally accomplish that was very special to me.
0:04:52 > 0:04:54Enjoy your weekend!
0:04:54 > 0:05:00Have a good one.
