But I wanted to post something he does on a regular basis that you might like to use also, if you have a 12-14ish year old. It is called Above and Beyond Five in A Row. He is reading the Newberry award winning book Hitty, Her First Hundred Years. And following the book of activities. It is pretty much self-guided and picks what he wants to learn about and do with each chapter. He keeps a notebook of what he has done. It covers art, cooking, history, science, language arts, and other things. We have both learned a lot from it!
He made gingerbread from the book
There is plenty of vocabulary and art
Learning the history of a quill pen and and how to use it
Science
Learning about what causes sea-sickness
