Institute of Geology took an active part in the Science Fair, which was held at the PVA EXPO Fairgrounds in Prague-Letňany in the first days of June. The fair presented over 100 expositions of most Institutes of the Czech Academy of Sciences and many other institutions and companies. Much like in previous years, the stand of the Institute of Geology attracted by the display of fossils and minerals but also by thematic posters presenting the Institute activities. Very successful was the observation of fossils with a microscope and geological quizzes: the successful responders could take away a mineral of their choice. The quizzes were attended, individually or in groups, by over 350 visitors of various ages. The stand was visited by about 2000 people! It became attractive for professional photographers, too. Therefore, seven photos of the stand were included in the official gallery of the Fair.
