Frogs and Fun at CSI

By Jonathan Ortiz & Dana Governara

Our trip to the College of Staten Island on May 29th allowed our class 824 to study in a nice college lab. The purpose of this trip was to dissect a frog. The first thing we had to learn was how to stay safe. We had to wear gloves to protect us; also we had to wear goggles to protect our eyes from getting poisoned from the chemicals.

We watched a virtual dissection on a screen to learn what to do first. Our class had to study the frog’s organs and find out where they were and if they worked any differently than then the human body. Our lab teacher told us that we can look through the stomach to see what the frog last ate. Jonathan’s frog didn’t eat anything, but I also found out it was a boy. Dana’s frog was different though hers was a girl (the frog had eggs) and it also didn’t have anything to eat. At first we felt it was disgusting, but kind of cool, and that we were going to be sick. First we had to cut through the skin of the frog. Then we cut through the muscles from the throat to just below the stomach. “It was interesting because we got to see the organs. The skin felt like rubber which was hard to cut,” said Anita Zekaj from 824

By the end we all felt like we learned so much about this frog and that a book can’t teach as much as we experienced here. This was something we thought we would never do in junior high school.
