We summarize the Design Reference Science Program for the Star Formation Camera (SFC), baselined as one of 3 primary instruments for the 4-m Theia space telescope concept. SFC is a wide-field ( 15'x19', >=280 arcmin2), high-resolution (18x18 mas pixels), mid-UV--near-IR (190--1075nm) dichroic camera that will deliver diffraction-limited images at lambda >= 300nm in both a Blue (190--517nm) and a Red (517--1075nm) Channel simultaneously. Our aim is to conduct a comprehensive and systematic study of the astrophysical processes and environments relevant for the births and life-cycles of stars and their planetary systems, and to investigate and understand the range of environments, feedback mechanisms, and other factors that most affect the outcome of the star and planet formation process. Via a 4-Tier program, we will step out from the nearest star-forming regions within our Galaxy (Tier 1), via the Magellanic Clouds and Local Group galaxies (Tier 2), to other nearby galaxies out to the Virgo Cluster (Tier 3), and on to the early cosmic epochs of galaxy assembly (Tier 4). Out to Virgo, SFC will be able to resolve individual luminous stars within galaxies. Interpretation of the panchromatic imaging is intimately tied to far-UV R >= 30,000 spectroscopic observations with the Ultra-Violet Spectrograph (UVS), also aboard Theia. Each step will build on the detailed knowledge gained at the previous one. Such a study, which addresses the origins and evolution of stars, galaxies, and cosmic structure, also has direct relevance for the formation and survival of planetary systems such as our own Solar System and planets such as Earth.
