My masterwork is an aquaponics system presented in the Budavári Elementary School. This is a system where the aquaculture and hydroponics is presented in a symbiotic environment and I intend to use it as a tool in education. It represents the natural hydrological cycle through the formed ecosystem and it can be used in science-related classes. On the other hand, it would teach responsibility through the caretaking. The central element of the system is the floating vessel designed by me, which is used as a base for the plants and reminds the viewer to the origins of the aquaponics.
