Lincoln Park Academy’s IB Biology Seniors learned the Mark-Recapture technique at Harbor Branch Oceanographic Institute. Over the course of two days, Mr. Messina and his students were able to estimate the size of a population of mangrove snails by capturing a small number of snails and releasing them back into the population. When provided the opportunity, students form a deeper understanding of the content with a hands-on approach rather than sitting in a classroom lecture.
