Seeing as this is one of my last classes with Bobby, I thought it might be beneficial to review the material that we have studied this year. I quizzed Bobby on topics ranging from the different types of nebulae to the classification of galaxies to the two main types of black hole. I started by asking Bobby what might be the one thing he'll take away from our time together, and after a moment's thought, he smiled and answered 'Nebulae'. He was also very proud that his galaxy poster has been displayed at the school for all this time. That was a lot of hard work he did!
