Where do the children go to watch Tom Robinson and trial with whom?

In Harper Lee's "To Kill a Mockingbird," the children, Scout, Jem, and Dill, go to watch Tom Robinson's trial with their father, Atticus Finch.

They sit in the colored balcony of the courtroom, separated from the white audience. This separation is a stark reminder of the racial segregation and prejudice prevalent in the 1930s South.
