Аннотация:In the conditions of quarantine in 2020 many museums faced the questions: "What to do? And How to work?" For the M.V. Lomonosov Moscow State University Earth Science Museum such issues are highly relevant, as the museum is located on the upper floors of the MSU Main Building (Leninskie Gory). According to guidelines established by the Russian health system during the pandemic, students couldn’t visit the museum, even in small groups. So, we decided to make digital versions of the museum’s lessons.Our museum specialists have developed a number of online (Zoom) activities. We had two important tasks in the pandemic period. The first task was - to improve the way we teach classes and to make classes interesting, which may contribute to increasing the quality of sustainable education in general (SDG-4). The second task was: to enrich the programs with environmental content, focusing on the state of urban ecosystems (SDG-11).The content of our programs covered such topics as - especially protected natural areas, conservation of biodiversity in the city, recycling of household waste, methods of determining the state of vegetation and reservoirs, etc. Most importantly, we were able to conduct online classes with practice, as a result of which schoolchildren mastered simple bioindication techniques and rules for the treatment of household waste in the city. Thus, 47% of schoolchildren for the first time learned what the labelling of solid municipal waste means, and 76% were able to understand how to determine the asymmetry of a plant’s leaf to determine degrees of adverse impact on the urban ecosystem.
