Brief information about the author’s course dedicated to crystal growth is provided. The education program gives general information of the mechanisms of crystal growth, the main growing methods, crystal formation in nature and under home conditions. Issues of the origin of the first group gemstones, the specifics of their formation in the laboratory, methods of treatment and application are considered. A large amount of information is given, that’s why the course is divided into four sections and clearly structured within each of them. This helps to make it easier to perceive. Online course design allows the lecturer to effectively interact with the audience.

The article summarizes information of the crystal morphological features of zircon from metamorphic rocks, its internal structure, crystal matrix chemism, and rare earth element distribution. These data make it possible to reveal discriminant features of zircon as depend on the origin of the substance crystallized and the conditions of its transformation during metamorphism. For a reliable assessment of the content of elements in zircon, it is necessary to perform a set of analytical methods, since the concentration of impurities varies significantly even in samples from the same rock. This makes it possible to determine the range of variations and to evaluate the dynamics of the distribution of elements in zircons from metamorphic rocks of various genesis.

This article is about the world’s only cabinet-museum of the great world scientist Vladimir Ivanovich Vernadsky. The museum celebrates its sixtieth anniversary in 2023, the year of the 160th anniversary of the scientist. The museum contains items which accompanied V.I. Vernadsky and his wife Natalia Egorovna (nee Staritskaya) from the moment of their wedding to his last days. There are many photos and portraits of relatives and friends of the Vernadsky family on the walls. Vernadsky’s library had about 7,000 books, some of which are now in the museum. The museum has many books by V.I. Vernadsky himself, published during his lifetime and in recent years. The sphere of interests of the great scientist was huge. The exposition and the library of the museum tell in detail about the creative path of the scientist. Having started as a mineralogist, V.I. Vernadsky created physical (energetical) crystallography, genetic mineralogy. He is the creator of radiogeology. His studies of living matter, comparison of its properties and composition with those of mineral matter allowed the scientist to create a new science –biogeochemistry. In his scientific activity, V.I. Vernadsky paid much attention to the development of his doctrine of the biosphere, the transition of the biosphere into the noösphere. Vernadsky was a significant public and political figure of pre-revolutionary Russia. One can learn about all this from the museum’s exposition and from the story of the curator of the museum.

Brief information is given about the samples of vernadite from the mineralogical collection of the Earth Science Museum, which were passed for display at the exhibition organized for the anniversary of V.I. Vernadsky. The history of the discovery and studying of vernadite and features of its chemism, modern concepts of its crystal structure, genesis as well as some practical applications are addressed. Attribution of the exhibition samples as vernadites is questionable due to the lack of information about their instrumental diagnostics.

Here is a brief overview of the author’s lecture series — an additional general education program “Mineralogical Journey into the Depths of the Earth and Back” dedicated to minerals characterizing the main layers of the Earth, namely: the crust, the upper and lower mantle, and the core. The Program provides a general understanding of the Earth’s structure and minerals, their main properties, and natural formation processes. It covers key minerals of the Earth’s crust such as quartz, gemstones like ruby, sapphire, emerald, etc., as well as mantle minerals, including diamond. Information on the application of these minerals in technology and the jewelry industry is also presented. During the preparation and conduction of the online course, the author implemented an individualized approach, which helps enhancing the learners’ understanding and increase their satisfaction. This course was developed by the author and piloted at the Earth Science Museum of Moscow State University named after Lomonosov. To facilitate the absorption of a large amount of information, the series is divided into four sessions and clearly structured within each one. The online format enables the lecturer to interact fully with the audience at any time convenient for the participants.

The article presents a retrospective analysis of the development of educational and enlightenment activities in the Earth Science Museum of Moscow State University named after Lomonosov from the moment of its foundation to the present. The following trends are highlighted: expansion of the forms and methods of museum pedagogy over time, introduction of interactive methods in the practice of the educational and enlightenment activities, work with various age visitor groups (from younger pupils and students to adults), as well as the use of digital methods in the educational process.
