How I describe it as a dumb pilot. Avoid trying to explain why it happens, focus on what happens.
An aerofoil is efficient at deflecting air below it as it moves through it.
An appropriately curved form is able to deflect the air more (and over a wider range of angles) than a simple flat plate (although a flat plate will still work).
The top surface of a curved aerofoil draws the air downwards more than a flat top plate will do it. The bottom surface of both an aerofoil and a flat plate also deflects it downwards if it travels with a slight angle.
If you can push air downwards, you are pushed by the air upwards.
The movement of the air caused by the aerofoil as it moves through it must correspond to a change in pressure. If you flap your hand it moves the air, your hand feels the change in pressure of the air.
You can look at the overall amount of air the wing pushes down and calculate lift. (Newton)
You can also measure the pressure of the air causing it to flow as it does around the aerofoil and calculate lift. (Bernoulli)
Both will give identical answers as they are simply answering the same question but from different perspectives.
Beroulli's thereom is derived from Newtons laws.
That is what happens.
Why does a curved surface deflect the air better than a flat plate? Much more difficult question. Avoid trying to answer it. If the student persists invoke magic.
