Interstellar turbulence is driven by strong inputs from various energy-providing sources, the strongest being supernova explosions. The turbulence in turn gives rise to a large number of observable phenomena. It is not unreasonable to think that the turbulence governs and regulates star formation and evolution in our Galaxy. In this talk we focus on two aspects of the turbulence, the growth of magnetic fields and the mixing of supernova ejecta. New insights from dynamical chaos theory are shown to provide us with new insights in understanding these phenomena.
