Volleyball is a really fast-moving game, played on an indoor court.
Players use their hands to hit the ball over the net.
Each team is allowed to touch the ball three times before passing it over the net to the other team.
Points are scored when the ball lands on the other team's side of the court.
In this week's challenge the winning team will be the first to score 25 points.
Emma and her netball team stormed their way to victory in the Volleyball. that now means the girls are in the lead five-three in Superkids.
