Research as most meaningful?

Right now I'm considering my most meaningful activities as I put together this year's application. Two of my three most meaningful are clinic- and service-oriented, and I'd like to write about research as my third. There are two approaches I could take for this: discussing what I did one particular lab, or taking a more general approach, discussing how current and previous research experiences have contributed to my education and how it might fit into my future. I think my largest concern... Research as most meaningful?
