All students must take at least one year of a biological lab science at Bronx Science, a requirement that can be satisfied either by freshman biology or, if students took biology in middle school, one of the many advanced electives offered, including AP Biology, AP Environmental Science, AP Psychology; non-AP advanced courses include animal ...
The MPN method involves taking the original solution or sample, and subdividing it by orders of magnitude (frequently 10× or 2×), and assessing presence/absence in multiple subdivisions. The degree of dilution at which absence begins to appear indicates that the items have been diluted so much that there are many subsamples in which none appear.
In addition, students must take at least one elective. Potential electives include AP Chemistry, AP Biology, AP Physics 2, AP Environmental Science, Disease and Forensics, Zoology, Science Ethics, and AP Psychology / Neurobiology.
