As I have resources ready I'll be sure to put course specific resources below! As a starting place, I'm often inspired by the work done by Perimeter Institute and Chris Meyer.

If you want to get started on some hands on activities for senior physics (SPH3U and SPH4U specifically), in the pandemic I created a bunch of at home labs students could do to experience physics while in a virtual course. These can be used at home today or brought into the classroom, depending on your comfort level and current restrictions you are facing in the classroom. You'll find demo videos here with sample student worksheets in each videos comments.
