By using spectra taken with the Infrared Spectrograph (IRS) aboard the Spitzer Space Telescope, in conjunction with optical, near infrared, sub millimeter and radio data from ground based observations, we construct model spectral energy distributions (SEDs) for Class I Young Stellar Objects (YSOs) in Taurus. We use the SED to infer specific values for the parameters that describe the structure of the system, such as the size and shape of the envelope. We use our modeling code to create SEDs from ~ 2 microns to 3 mm and match these models to our original spectrum and ancillary data, giving an interesting view of the structural evolution of Class I protostars.
