One of the objectives of the project to develop a youth museum under the auspices of the MSU Museum of Earth Science is the popularization of scientifi c research and the creation of mechanisms for scientific and educational engagement among groups of early-career researchers. Within this framework, the annual Science Festival held at Moscow University assumes particular importance. Since 2016 the Museum of Earth Science has collaborated with the scientific and educational expedition Flotilla of Floating Universities, which ope rates in the Volga, Don, and Caspian regions. Presenting the youth museum as a mobile and network-based project at the Science Festival has proven most eff ective when combining three mechanisms: the exhibition format — temporary display of natural specimens and artifacts collected by young naturalists during expeditions; the presentational format — demonstration of popular-science books, films, and scholarly works produced with the participation of young colleagues; and the interactive format — the organization of specially designed engagement platforms. This approach was tested at the All-Russian Science Festival held on the MSU campus in 2023–2024. The exhibition featured finds from the Flotilla of Floating Universities (including prize-winning entries from the first All-Russian competition Youth and Museum) in the Volga region, and was displayed in the pavilions of the Museum of Earth Science and the MSU University Gymnasium. Key products created in collaboration with the youth museum project included the book Vernadism in the Contemporary University and the popular-science film The Brotherhood of Scientific Creativity: Vladimir Vernadsky’s Floating University, continuously screened throughout the event. Specially designed interactive platforms were also presented, including Virtual Reality in Museum Space: VR-Travel into the Geological Past of the East European Plain (developed by winners of the Youth and Museum competition), which enabled visitors to experience participation in an actual Flotilla of Floating Universities scientific expedition through VR technologies and curated video content, and S.N. Vinogradsky’s Column: A Living Demonstration of Ecosystem Evolution in Real Time. In addition, an expeditionarylaboratory practicum, Cosmic Traces on Earth, was conducted by students of the MSU University Gymnasium.
