Welcome to the wonderful world of Biology!! On this page, you will find everything that you need to be successful in this course. I teach both ends of the spectrum--9th grade Biology and 12th grade AP Biology. Those students in 9th grade will get a foundation that will enable them to be successful in AP Biology should they take it their senior year. It is my privilege to share my day with the students at PHS and to provide a positive, comfortable learning environment for them.
