We present a spectroscopy study of 37 emission line galaxies that were selected from their colors in three photometric bands responsive to the Balmer break. These galaxies span a redshift range from 0.045 to 0.93. The studied sample has multiwavelength photometric data from ultraviolet to mid-infrared Spitzer bands. We study relations between star formation rate (SFR) surface density (Σ_{SFR}) and stellar mass surface density per time unit (Σ_{M_{*}/τ}) as function of redshift. We found that both quantities are larger for higher redshifts. We also study the SFR and specific SFR (SSFR) versus stellar mass relations. More massive galaxies have higher SFR values and lower SSFR values than less massive galaxies. Furthermore, at a given mass, high redshift galaxies have on average larger SFR and SSFR values than low redshift galaxies.
