This paper presents the role of social networks in the lives of primary school students. It could be said that social networks are a way of living for young people. Communication and face-to-face socializing are increasingly being replaced by virtual comunication and messaging by social networks. The purpose of the research was to examine which social networks young people most often use and what is their role in young people lifes. The research was conducted on 237 respondents, primary school students. Out of the total number of respondents, all 237 use social networks, which confirmed the initial assumption of the conducted research. Research has shown that young people most often use social networks to exchange messages with friends. They also use social networks in school to communicate with teachers and for better understanding the teaching content. The results of the research also showed that a large number of students, as many as 160 (67, 5%), encountered some of the inappropriate behaviors on social networks. This data only says that young people should be educated about the proper use of the Internet and approach the use of social networks with caution in order to avoid the negative aspects of using them.
