A real easy thing to keep in mind is that Ionian mode is the major scale and the Aeolian mode is the minor. So the minor scale is the 6th degree of its corresponding major. Both scales will use the exact same notes. For example, if one mode has a B-flat, the other also uses the B-flat. In fact, all the modes of a single scale use the identical notes. There's ways to use them to get jazzy or bluesy effects and so on. I'm not much of an expert on that. But a good music teacher going one-on-one with you would be a big help.
