Phrasal verbs are those pesky verbs that combine a verb with a preposition or adverb (which we will call a verb particle).  The meaning of these verbs doesn't seem to have anything to do with the root verb or particle.  When Susie throws up, what does she throw exactly?  Or if Kevin gives in, does he give anything?  They don't seem to make sense...but there are SO MANY of these verbs in English, and new ones are being created every day! Seriously:  It's 2020, and I just spotted a road sign saying "Mask up!"  Well good news...these little verbs actually do have some logic to them, but in order to understand the logic (without reading pages upon pages of research), we need to take you (and your students) through some visualization exercises into the world of metaphor and imagery.
