Already on 18 September our small delegation consisting of: Wiktoria Tomecka, Piotr Kania and Hubert Knap conducted workshops for students of Secondary High School. Andrzej Frycz Modrzewski in Rybnik. Of course, in addition to precipitation reactions, the students had the opportunity to repeat the graduation material from the Trommer test and the degrees of manganese oxidation. The students quickly became involved in both the lecture and the workshop. They'd come up and ask all kinds of questions. They liked the experience with fluorescence the most, because they have no contact with it every day - describes her observations Wiktoria, a graduate of the Second High School.
