When she arrived to her new school, she used telekinesis in class to telekinetically rotate a pencil on its tip. When she lost concentration, the pencil fell. This marks Sarah as the first witch to use telekinesis in the movie.
Nancy Downs is also a user of this ability. Most notably, she used this power to kill Chris by opening a window and pushing him out of it. Secondly, she used it to unlock a bathroom stall that Sarah was in.
