  The Schwarzschild metric is derived in a manner that does not require
familiarity with the formalism of differential geometry beyond the ability to
interpret a general spacetime metric. As such, the derivation is suitable for
an undergraduate course on general relativity. The derivation uses infalling
coordinates that are particularly well adapted to the situation, as well as
Einstein's equation in the simple form introduced by Baez and Bunn. That
version of the vacuum Einstein equations corresponds to requiring a particular
local Newtonian limit: that, to first order, the deformation of a "test ball"
of freely falling, initially-at-rest test particles is governed by the tidal
forces of Newtonian gravity.
