Hockey is a popular sport that requires several pieces of equipment in order to play. The term 'Hockey Need' refers to the four items necessary for playing the game: a PUCK, ICE, a STICK, and a CAGE. A PUCK is a small, hard rubber disc that is used as the ball in hockey. ICE is the surface on which the game is played. A STICK is a long, curved piece of wood or composite material used to hit the PUCK. Finally, a CAGE is a protective helmet with a face mask worn by players to protect their heads and faces.
