Not sure if this is the right forum for my question, but here it is anyway

I emailed Phil a while back asking him if he knew where I could get curriculum for a high school astronomy course (grade 11 or 12 level)

I'm a teacher in Ontario (Canada) and have always wanted to teach astronomy, but there is no such course here.

Phil referred me to someone else, but I never got a response, so I was hoping that someone here might be able to guide me in the general direction.

I also have a question about singularities: Can different singularities have different amounts of energy even though they are infinitely small? (i.e the big bang singularity vs a "regular sized" black hole)
