     Welcome! 2023 will be my 16th year of teaching at Freedom High School.  Over the years, I taught Earth Science, Biology, Chemistry, and Physics. As you can see by the categories above, I currently go between teaching science (APES) and technology with an emphasis on Visual and Performing Arts (VAPA)

    Since we began using Canvas in 2020, most of our content updates for each class will be on that site so this site simply gives an overview of all my classes. At the top of this page, you will see links to specific classes, and when you click on one, it will open a list of subcategories that pertain to that class.

     

    'It must be remembered that the purpose of education is not to fill the minds of students with facts... it is to teach them to think, if that is possible, and always to think for themselves.'  - Robert Hutchins
