I think an overview and what kinds of results you are looking for is more important for the research essay. Hypothesis, projects and why you like it/what significance does it have can be mentioned. The adversity essay you have is good in my opinion, just make sure you highlight why your research project was harder than the average one and the ways you overcame having a tougher project. Wouldn't worry too much about results, but everything is kept private I'm pretty sure. I couldn't go into too much detail the on significance of my project, I thought it was pretty obvious but I just didn't have enough space.
