After always being a rather good student, I met my nemesis in high school and it called itself, Chemistry.   The classroom itself was always fascinating to me with its knobs and handles, hoods and sinks, and tables meant to extinguish flames.  I looked forward to learning about these tools and putting them to use.  Like so many things, my expectations of what it could be didn’t entirely capture the reality.  Chemistry was a danger zone.  With experiments that  could explode and react and create other substances, it was a class full of learning but most of it not what you could find in a book.  Labs were the best part of the learning and the most important truth was follow directions one at a time and focus on each step and not the product you were trying to get.
