Children will be able to construct models of wooden ships. The mock-ups are copies of ships found in the last underwater archaeological expeditions in the Black Sea. The children will be able to assemble and disassemble them according to drawingс and photoс, accompanied by information about the ship and the time it sailed. The game “Underwater archaeologists” will be related to exploring the hidden secrets of the Black Sea. For this purpose, children will use a periscope equipped with virtual reality glasses and video footage of the underwater archaeological expedition. The installation will allow participants to “explore” the bottom of the sea, discovering sunken objects. The “Marine Researchers” Exposition will be linked to research studies and demonstrations how underwater archaeological expeditions are made.
