Today, the subject for this eighth-grader was E-sharp, and we started by discussing the effect of sharps in the first place...
ME: So what does a sharp do to a note? And I want a more detailed answer than "it makes it sharper."
KID: Aww man, that's what I was gonna say!
ME: No, I want a little more detail than that. So again, what does a sharp do to a note?
KID: Makes it louder?
