Class Experience

I have a PhD in Microbiology but soon thereafter became certified to teach because I wanted to teach kids. I have many years experience teaching science at the elementary, middle, secondary and college levels.  I have taught Microbiology in both online and classroom settings. Even in an online setting, I make my classes as hands-on, interesting, fun, and rigorous as possible. 
Students will need a notebook for notes and small activities.  For full participation, students can purchase a set of nutrient agar plates.  A microscope is a true bonus for this course (but not required), as is methylene blue to view cheek cells. 
1 hour 30 minutes per week in class, and maybe some time outside of class.
