Introduction - Chilly adventures only on CBBC

The CBBC Channel gets serious this winter with Serious Arctic, which follows the amazing adventure of eight young volunteers as they search for the effects of global warming on the glaciers and resident polar bears.

There's also a special week of programming on Newsround, looking at what life is like for young Muslims in the UK today.

For Sunday teatimes, there's an all-star cast lined up for CBBC's adaptation of Kidnapped, Robert Louis Stevenson's classic tale.

And new comedy series The Crust promises to get your mouth watering as CBBC's Reggie and Dev star in a sitcom based on a pizza delivery service.

On CBeebies, young viewers can keep warm with the return of Boogie Beebies, with more great dance routines to get everyone dancing around the living room.

And a brand new series - Razzledazzle - aims to help pre-school viewers learn the joy of language through play, stories, dance and song.
