A game activity for children will turn the introduction to the Urals into a small exploration of stones, crafts, and museum stories. The kids will examine gemstones, learn about the famous cutting factory in Yekaterinburg, discuss malachite, jasper, amethyst, and other minerals, and then create a colorful sand appliqué as a keepsake. The Ural Mountains can easily be imagined as a large natural treasure chest: inside, transparent crystals, dense patterned stones, green malachite, iridescent agate, and other minerals lie side by side, from which jewelry, household items, and keepsakes have been made for centuries. In the game activity, children are invited to explore this topic through curiosity, tactile experience, and a museum narrative that is understandable to younger schoolchildren. The meeting is part of a summer program based on the dreams of young visitors to the exhibition "Islands and Captains." This time, the focus will be on the stone riches of the native land and the people who knew how to turn natural materials into expressive products. The kids will learn why the Urals are often called the land of gemstones, how precious and semi-precious stones differ, what properties minerals can have, and what stories are associated with them. Where to go in Yekaterinburg is known by KudaGo.
