The Emergency Medicine Interest Group organizes an elective that you can do any time during the first two years. It's a great experience by which you spend 6 four hour shifts in the ER shadowing an attending or resident. I'm a 2nd year and did it last semester.
I got to help intubate a patient, stitch up this guy's head which had a 5 inch laceration, try to resuscitate a patient, and got to observe all sorts of things like pelvic exams, putting in femoral lines, lumbar punctures, etc.... I highly recommend it. You'll see more in Newark than most other places that I can think of. It's especially great when you're thinking about EM, like I am. It has been one of the most eye-opening experiences that I've had in medicine so far.
If you attend NJMS in the fall, just keep your ears and eyes open for announcements for it. There will be advertisements from EMIG that will tell you how to get signed up and how to go about getting involved.
