Morse school eighth-graders get a lesson from Cambridge Health Alliance microbiology medical technologist Aurora Fernandez at The Cambridge Hospital Pathology Laboratory on Oct. 25, 2005. The lab visit by eight Cambridge students was part of an all-day “Explorations” program organized by Dr. Joan Reede, the Harvard Medical School dean for diversity and community partnership, to encourage middle-school students to think about careers in medicine  with talks at the Medical School and visits to facilities at Harvard teaching hospitals.
