Augmented Reality (AR) is a live, direct or indirect projection of the physical-real world which allows users to experience the surrounding environment as it is, in real-time, enhanced with digital and/or interactive content. It seems that AR can be exploited for teaching various disciplines. In this paper, the preliminary results of a study regarding a teaching intervention about science education in primary school and specifically the topic of the water circle are presented. The AR content was deployed through the ENTITI creator application.
