What Types of Content Should Be Included in A Poster Presentation of Unfinished Work?
Rather than 4, you should say something about your hypotheses. You don't have "expected" results. You only have hypotheses and results. The results may support your hypotheses or not. 

And rather than 5 you should say something about the potential significance of the study. Why is it worth asking the question and posing the hypotheses? 

These two items should be #1 and #2, actually. Your #4 and #5 can only be discussed properly after you know more. 



In a poster session for incomplete work, the attitude should be "What do we hope to learn (not show), and how do we go about testing it?"
