The application was developed using the MESOVA methodology, employing technologies such as Unity, Vuforia, and Visual Studio with the purpose of enhancing the educational experience for elementary school students. This innovative tool integrates augmented reality with the pedagogical principles of MESOVA, standing out notably from other research. Focusing on topics such as scientific knowledge and design and construction skills, the application not only provides information but also includes games that encourage interaction with the universe and planets, offering a participative and meaningful educational experience. The pretest results revealed an average scientific knowledge of 9.75%, significantly increasing to 15.55% in the posttest. Similarly, design and construction skills, initially evaluated at 8.24%, experienced a remarkable increase to 14.99% in the posttest. The adaptability of the application to the specific needs of elementary school students creates a stimulating and personalized learning environment. The combination of MESOVA and augmented reality enriches the educational experience, promoting understanding, collaboration, and critical thinking among students. In conclusion, the initiative goes beyond providing basic information; it becomes a transformative educational resource that equips students with fundamental cognitive and social skills as they explore the universe through augmented reality. Ultimately, it highlights the potential of technology and pedagogy to create a dynamic and enriching educational environment for elementary school students."
