Who is better at sport - girls or boys?
Well, Sportsround has a new challenge for some of the sportiest kids in the country.
Each week, one boy and one girl will be challenged to try out a new sport that they've never tried before. Whoever wins will get a point for their side.
The score is currently 2-1 to the boys.
Will the girls put up a good enough fight to level the scores?
THIS WEEK'S CHALLENGERS: THE BOY
USUAL SPORT: Swimmer
JOSH SAYS:"Charlotte's got a head start because she's a water skier, but I'm going to try my best!"
THIS WEEK'S CHALLENGERS: THE GIRL
USUAL SPORT: Water Skiing
CHARLOTTE SAYS: "It's really good fun. The competition is going to be tough because Josh is good as well."
THIS WEEK'S CHALLENGE: MOUNTAIN BOARDING
Charlotte mountain boarding
Mountain boarding is a pretty extreme sport, which comes from snowboarding.
It often takes place on a bumpy hill on a board smaller than a snowboard.
It takes a brave person who's not afraid of falling over to give it a go!
Charlotte won the mountain boarding with amazing speed down the hill. So now it's level with two wins to the boys and two wins to the girls.
