The project involves the exchange of prototypes of teaching aids for diffrent sciences (biology, physics, chemistry, math and others) between the schools (models, mechanisms), designed and made by the students themselves. The exchange serves the purpose of mutual testing of prototypes in order to improve them and then implement them in the educational process. We would like to see the problem from diffrent points of view and diffrent sciences. We believe that by creating and constructing, we learn better. Feel free to join us!
