Bernoulli's principle is certainly involved, but the full explanation is more complicated and arguably beyond high school level:

See #3. Wings are not constrictions in a tube.
From your source:
Sure, it might be more complicated and there are other forces at play. Also, top and bottom air molecules may not reach the backside of an airfoil at the exact same time, but that doesn't diminish the effects of this pressure differential on lifting force.
Sorry, i meant in the classical form of bernoulli's equation it's been a while. It's common for people to suggest the wing is half a venturi, then try to apply 1DOF algebraic equations which don't work here.
