In primary education, a large proportion of teachers highlight the difficulties experienced by their students in understanding scientific texts and in some cases the gradual dismotivation towards reading science books. There are a number of obstacles that emerge from textbooks, such as vocabulary, or that images or graphics used do not attract much interest when compared with other multimedia resources. At present, there are resources that use increased reality that can be applied to the educational context, making it easier for students to manipulate virtual objects through markers as if they were real objects, performing these operations naturally and intuitively, without any additional hardware mediating in the alumno-computating relationship. This work shows the results of an extension experience developed in 2014, where the technology Increased Reality is used to teach subjects covered in natural sciences at the primary level.
