What I teach now
SCH4U Chemistry
Grade 12 Chemistry → organic chemistry, thermochemistry and rates, equilibrium and acids / bases, and electrochemistry. I've built full 15-lesson units for each, with worked examples and answer keys.
Computer Science
ICS3C, ICS3U and ICS4U → Python, Java, and the ideas underneath them: data structures, efficiency, and building real programs.
ICD2O Digital Technology
Grade 10 digital technology → hands-on, practical work with technology.
Teaching resources and lesson materials →
YouTube channels
ChemistNate
Chemistry lessons, including a long series of Lewis structure videos.
For teachers & students
I publish teaching resources → chemistry lesson materials, math resources, and a lesson directory → on the Teaching page. They're free to use.
