The scientific employees of the Center prepared a lecture and demonstrations entitled “Playing with Chemistry”. During the meeting the children had the opportunity to become familiar with basic chemical concepts, and do simple chemical experiments under the watchful eye of Róża Trzcińska (M.Sc. Eng) and Daria Lipowska (M.Sc. Eng). The experiments allowed them, among others, to become detectives and read “hidden inscriptions”, to make milk whirlpools, see a volcano in a cup, and learn about the properties of an exquisite, thermosensitive polymer.
