If, let's say, I am making a plan to participate in a new research project about how humans form memories, I could write:
The previous plan is vague, but that is the point. When entering a new field, it is impossible to already know everything about it, and so your plan should be about acquiring details in order to make a new plan that is more refined. This new plan can be written out like the one I've done, but if you are now confident in what you are going to do, use that confidence to go do it... with the approval of your research mentor, of course!
Further, the reason I've put the word "review" into bold font in the first part of my example plan is because this is a type of scholarly article that will likely be incredibly useful to you. A review is not a paper based on a novel study or experiment, but is instead a paper dedicated to summarizing and offering a holistic perspective on the current state of a field of study. I cannot stress enough how amazing review papers are if you are new to a field. In the case of AP Research, all of you will be new to the fields you are working in.
I don't mean this at all in a negative way; when I join a new laboratory, I spend hours reading review papers pertaining to the field that they are studying.
