Currently, the issue of educating skills to prevent drowning accidents is an urgent issue for the entire society. Educating drowning prevention skills for students in general and primary school students in particular helps them correctly perceive the importance of practicing skills to prevent drowning accidents. We propose the idea of using 3D books combined with AR technology as a useful choice in the 4.0 era. This will bring realistic, vivid images that are close to primary school students, creating excitement in the learning process. The application of AR technology is a breakthrough in primary school teaching to contribute to improving the quality of teaching Science as well as other elementary subjects.
