I was also struck by the fact that the director passes on outdated information to children, e.g. there was a periodic table of elements in the class, which was almost missing today, the complete 7th period. He also talked about 6 rare gases, of which we have known since 1999. This is something I would like to watch out for. Subsequently, I attended a science class at a six-year-old with a younger teacher.
