The 1M1 class celebrated the last day of the school term with a field trip to the Trepang Museum, where they had an entertaining quest "Find the Golden Trepang", an informative excursion and a story of a long-distance captain about sea adventures.
The guys plunged into the underwater world of the Sea of Japan, looked at live sea cucumbers in the aquariums of the museum, were surprised that, it turns out, the closest relatives of trepang are starfish and sea urchins. And trepang himself has been living in the world for 500 million years!
