My name is Mr. Charles Jahn, and I will be educating your children in science for the 2018-19 school year. My certification is in both biology and general science with experience teaching chemistry and physical science concepts. In addition, I have Masters of Education Degree from Grand Canyon University and a Bachelors of Science Degree from Saginaw Valley State University. Plus I'm a pride graduate of Croswell Lexington High School.
I am excited to start my fifth year at Cros-Lex High School. During my first year here at Cros-Lex I’ve involved myself in the DNR Salmon in the Classroom Project along with launching the Pioneer Innovators Club that design, build, and program Robots.

Teaching science and using technology is a huge passion for me. Thanks to my preparation of a bachelor’s degree in science with a major in biology and minors in chemistry and psychology in addition to a master’s in technology education, I feel I provide a diverse background that assets students in classroom. Both my experience from both Tekonsha High School and working in Florida for those seven years have made a huge impact on my classroom's learning environment.
Before coming to Cros-Lex, I spent four years, working at Tekonsha High School, in Tekonsha, Michigan, teaching 7th grade science, 8th grade science, Biology, Biotechnology, Chemistry, Earth Science, Environmental Science, and Physics. Before my employment at Tekonsha, I worked at Neptune Middle School, in Kissimmee, Florida, teaching integrated science to sixth graders from August 2007 to September 2010.
During college I was a substitute teacher in the Croswell-Lexington School District and an assistant laboratory technician at Saginaw Valley State University in the Biology Department. There I developed and crafted my skills and techniques from preparing biological laboratory experiments.
