Bobby is almost finished with his galaxy poster. We printed the remaining figure captions, primarily the names of the objects portrayed. While gluing the photos and captions onto the background, I quizzed Bobby on various astronomical subjects. We reviewed the different galaxy types to begin with. When I asked Bobby to name the planets in the Solar System, not only did he know them by heart, but he also knew in which order they are from the Sun. We also discussed the difference between asteroids and meteors, and then between meteors, meteorites, and meteoroids.
