Marking the death of a massive star, and the birth of a neutron star or black hole, core collapse supernovae bring dramatic change to their circumstellar environment through their ejecta. Carrying 10^51 ergs of kinetic energy and a rich-mix of newly synthesized atomic nuclei, the spreading ejecta provides hints about the inner workings of the supernova itself, revealing features originally hidden deep inside the stellar core. We will discuss our emerging understanding of the convectively unstable, neutrino-driven explosion mechanism, highlighting the imprint it leaves on the morphology and isotopic composition of the ejecta. Ultimately, observations of such features, in supernovae and their remnants, will provide the confirmation of the simulations and verification of our understanding.
