a scale is simply a series of notes that produce a particular sound, no matter where they are played.
e.g a C major scale is made up of C D E F G A B
and a G major scale is made up of G A B C D E F#
the notes change but the overall sound doesn't
I suggest that you consider taking lessons and get taught this properly.
Hope i made sense:)
