The first metals in the universe were created in the supernova (SN) explosions of Population III (Pop III) stars, and their remnants are recorded in the abundance patterns of extremely metal-poor (EMP) stars. The properties of Pop III SNe can thus be constrained by comparing models of their nucleosynthetic yields with abundances in EMP stars. We find that variations in yields in our Pop III SN models account well for the elemental patterns discovered in the 17 most metal-poor stars with [Fe/H]<-3.5 discovered to date. Larger samples of EMP stars, obtained by ongoing and planned EMP star surveys such as SEGUE and Skymapper, will unveil the properties of primordial SNe.
