One of the ways to develop and enhance students' scientific literacy is by using various educational problems and tasks. These tasks are designed based on real-life situations that simulate specific practice-oriented scenarios. Extracurricular activities, as an integral part of the educational process, provide the opportunity to implement these tasks. This article presents the practical experience of organizing the first STEAM festival in Uzbekistan, analyzing its role in the development of scientific literacy among schoolchildren and students. It demonstrates that organizing such festivals contributes to popularizing science among learners, attracts their attention to the scientific activities of researchers, their studies, and promotes the development of scientific creativity and literacy among schoolchildren and students.
