In this thesis we explore the relationship between the formation of protostars, and the influence of protostellar outflows on their environment using Infrared Spectrograph onboard the Spitzer Space Telescope. First we introduce the modern understanding of protostellar development advanced by the IRS_Disks guaranteed time program. Next we explore the FU Orionis phenomenon, an IRS_Disks dataset of flaring stars undergoing a burst accretion event. Finally we present a suite of data on Herbig Haro flows in Cepheus A to determine whether protostellar outflows can dissociate a wide angle cavity in their natal cloud.In the standard picture of star formation, a small part of a cloud composed primarily of molecular hydrogen is compressed, slowly collapsing on itself, coalescing into a dense clump of material heated by the collapse to high temperatures.
