Some of the commonly given theories are wrong though,
Now you're going to tell me that the lift pixies aren't real either, aren't you? You're a hard one to convince, you know.
I think every explanation of lift to a student should start with an empirical description: this is what happens with a flat plate, this is what happens when you change the AoA, when you introduce camber, when you introduce thickness, when you extend flap... That's a lot more use to the student than trying to explain why the lift is created. The rest can be saved for rainy days on PPrune...
