Abstract:  Metal-poor galaxies are the key to understanding star formation
in a nearly pristine interstellar medium, and may provide a template for
understanding the formation of the first stars.  Extremely metal-poor
galaxies are extremely rare; among the 1,000,000 spectra released by
Sloan, 19 have log(O/H)+12 < 7.65.  We have devised an efficient technique
to find new extremely metal poor galaxies, and discuss the scientific
questions a student might address with a statistical sample of these
objects.
