Hey there Neurotic1234!
Welcome to the forum!
Also, congratulations on getting a research elective at Johns Hopkins---you'll love your time there!
What happened in my scenario was that I had signed up for a research elective in Pediatric Ophthalmology which was to span six weeks during the summer.
However, my faculty member at JHU was gone for the first week when I arrived there due to him having prior commitments so my six week elective was in reality only five weeks long, which was much too short for any real research work to be completed. Therefore my elective mostly became a clinical one and I was fortunate enough to go on rounds with my faculty advisor and even got the amazing opportunity to assist in eye surgeries right next to the doctor himself.
Here's a few pics from my time there when I assisted in an eye surgery:
