The digital revolution has transformed the ways of doing, acting, and training in the university field. For this reason, as an objective of this work, social media was used to generate and share knowledge related to sustainability, classification of living beings, and the functioning of the human body. The information was collected through questionnaires, that were completed before and after the intervention program, as well as the work carried out by the students. The participants were 131 students enrolled on the Primary Education degree course of the University of Murcia. The students were well aware of social media, although initially not their educational use. This perception changed when having to make concrete proposals with Instagram and Pinterest, since students valued the wide potential of the use of these networks in teaching. As a result of this intervention, 266 images were generated on Pinterest related to the classification of living beings and 67 about the devices and systems of the human body. Additionally, in terms of the activity on Instagram, 213 publications were created, reaching 1454 followers and 7885 likes. In addition, the participants recognized social media as a source of resources for education, and therefore teachers must explore all the possibilities they offer.
