About the PBJ exercise, last semester (I'm in grade 10 right now), we had to do the same thing in Chemistry, except for a lab. It was teach us to provide detailed instructions in the lab write-ups. Almost no one in the class had detailed enough instructions. It worked like a charm. After that, on the rest of my labs, I went in a lot of detail in the instructions. I have to agree that it is a great way of teaching, and it would be amazing if every student encountered it at least once in their schooling. Especially at a younger age, it would instill an attention to detail in the student, which would serve him well for the rest of his life.
