How about verifying that the path of a projectile in a uniform gravitational field really does minimize the action?

Since we know the path from Newtonian mechanics is a parabola

y = h - ax

it would be interesting to pick a one-parameter family of curves, say

y = h - b

that has the same endpoints. Then calculate the action (the time integral of kinetic minus potential energy) as a function of n and show that it is minimized for n=2.
