A large observational effort with the ESO telescopes allowed us to obtain deep, spatially resolved, near-IR spectra of a complete sample of Lyman-break Galaxies (LBGs) at z~3.1. These observations were used to obtain, for the first time, the metallicity and the dynamical properties of a sample of galaxies that, albeit small, represents the total population of the LBGs. We propose to use IRAC to accurately determine the stellar mass of these galaxies to address two closely related issues: 1) measure the mass-metallicity relation at z~3 and its evolution to z=0, to study the chemical version of galaxy 'downsizing'' and compare the results with the expectations of recent models of galaxy evolution involving stellar and AGN feedback and galaxy merging; 2) compare the dynamical with the stellar mass, and relate these quantities with gas mass, SFR and metallicity to obtain the evolutive stage of the galaxies. The IRAC observations are a crucial step to obtain a reliable stellar mass and obtain a full descriptions of this unique sample of LBGs.
