• Welcome to Ms.Jerro's class. I teach Biology and Environmental Science. It has been my life long dream to be a teacher and I am so thankful to be fulling that dream here at Corsicana High School. My classroom is a safe environment where students are encouraged to be critical thinkers. Einstein said "Everybody is a genius. But if you judge a fish by its ability to climb a tree,it will live its whole live believing that it is stupid." My goal is for all of my students to find their genius, whether its climbing a tree or swimming a stream.
