Help with my AP US gov Summer ignment, Bloom's Taxonomy?

Okay, so Bloom was this educational psychologist and Bloom's Taxonomy is a clification of "levels of intellectual behavior important in learning". The lowest level is knowledge, next up is understanding, then application, ysis, synthesis and finally, the highest is evaluation. So you have to demonstrate that you have studied one of those topics at each level, especially the highest one, is what I'm thinking. Every topic on that list can be a good topic, the key is to pick the one you find the most interesting, then do some research. This is an AP cl, so they want you to use your brain.
