DESCRIPTION:Metals and dust are produced by stellar processes\, hence\nthe
 ir abundance traces the star formation history in galaxies.\nHowever\, met
 allicity\, dust content\, and their distribution within\ngalaxies\, are al
 so subject to several other processes involved\nin galaxy evolution\, such
  as outflows\, inflows and merging of galaxies.\nTherefore\, the evolution
  of metals and dust through the cosmic\nepochs provides important informat
 ion on the mechanisms involved in\ngalaxy formation and on their relative 
 roles.\nI will review some observational results on the metallicity and\nd
 ust evolution in high-z star forming galaxies\, by also emphasizing\ntheir
  relation to other galaxy properties\, such as the star formation rate\,\n
 stellar mass and dynamics. I will mostly focus on the redshift\nrange 3<z<
 7\, the early epoch of galaxy formation.\nObservations tend to favor scena
 rios of galaxy formation\ninvolving prominent cold gas inflows\, which hav
 e been recently proposed.\nHowever\, there are still some puzzling observa
 tional results that\ncannot be easily explained by current theories.\nI wi
 ll present plans for future observing programs that may\nshed light on suc
 h open issues.\n
