These classes are offered to pupils in the 4th, 5th, and 6th grades of primary school and aim at familiarizing them with the terminology of natural sciences in the Greek language. Natural sciences classes in minority primary schools are taught in Turkish. Therefore, those pupils of minority primary schools who continue their education at public secondary schools encounter difficulties regarding the Greek terminology. The classes utilize specially designed educational materials. Children conduct experiments by themselves, solve problems, and use special software that helps them learn the Greek terminology of natural sciences.
