In which I embark on a unit planning odessey

The purpose of this blog is to track my planning for my long practicum.  I will be teaching grade 7 at in a challenging class and I have have to teach:

Science - Chemistry
Social Studies - Ancient Greece
Math - Perimeter, Area, Circumference and Area of a Circle
Language Arts - Lit Circles on dystopian fiction, and graphic novel writing
French - Winter Sports
Physical Education - Badminton
Health and Career - Drug use in sports and eating for sporting health

I am looking for a way to create a through line that connects all of these things, and I think the question "How has Ancient Greece impacted the present culture in Canada?" might be able to do this.  But I need to work on how this will work.
