The first journalist arrives and checks the wires for the stories Newsround might cover that day. They make a list of possible stories to be discussed at the morning meeting.
Sometimes people set off much earlier if they have a long drive to a shoot.
The programme producers and the rest of the team arrive.
The morning meeting. The team watch yesterday's programme to see what was good and what could have been done better.
They then discuss which of today's stories should be covered, and how to make them as interesting and fun as possible.
The producers make a running order and allocate which assistant producer is going to cover which story.
The assistant producers and reporters go out and film their stories, interviewing children and famous people.
They also write the scripts and find other pictures they might need - either from the library or from picture feeds.
The afternoon meeting. The producer of the programme tells the graphic designer all the graphics that will be needed for the stories that day.
The director (who runs the studio) looks at the running order and works out how to run things technically.
2.00pm until the show
The assistant producers and reporters go down to the edit suites to cut their stories with a picture editor.
The graphic designer prepares the graphics for the programme. He also tells the assistant producers when the graphics are ready for them to add to their stories.
The camera and lighting operators get the programme ready in Studio 7.
The producer also has to check that the programme is running to time - and shortens part of the script if it's not!
The presenter goes into make-up and then to the studio to start rehearsing. Sometimes there's a live trail to do as well!
If there is an important breaking story all the team can be working hard to get the story ready for the programme. Then there is not so much time to rehearse.
Showtime! The producer sits in the gallery with the technical team: the director, the sound and vision mixer, and the person who watches the time carefully to make sure the show doesn't over-run.
In the studio the presenter listens to the producer's instructions through their earpiece. They read the autocue to bring all the day's stories to you.
Some people stay to plan the next day's stories and do some extra research. But for most of the team this is hometime!
