Roast the Ghost One
Grade 5 and up.
Set a timer for six minutes.
Write everything a ghost did in its living life to cause it to be punished with an existence of floating aimlessly for an eternity with no friends and with nothing to do, but to mourn its many bad deeds.
Concentrate on actions, the bad things it did while alive to its enemies and friends. Try to write constantly, never lifting your pen or pencil from the page.
After the six minutes are up, highlight all the good stuff, and then write a poem, song, or story (picture book or part of a YA novel chapter) based on your notes.
Spook us out.
