Abstract The Federal University of Goiás (UFG) and the University of Brasília (UnB), in partnership with the company Eletrobras Furnas, have developed research and, based on this, extension projects aimed at education in a broad sense, in which they seek to disseminate and popularise technical-scientific knowledge. This paper aims to present and evaluate educational actions carried out in the area of soil science and geotechnics applied to engineering, geography, and the environment. To do so, the educational experiences developed within the scope of two extension projects are shared. Besides that, the relevance of publishing books and primer, with language adapted to lay society, within the scope of research projects, is analysed. The results collected regarding the effectiveness of the extension actions as a tool for learning point to a positive evaluation by the students. Furthermore, social networks are an important tool for scientific dissemination and have the potential to disseminate knowledge more widely than in a classroom course. By comparing the number of citations in Google Scholar of the books and booklets with the papers arising from these projects, one can observe the reach of this type of publication, although its purpose is the popularisation of science, with reach in places not considered in the technical-scientific publication metrics. Finally, for effective scientific development, it is necessary to have public policies, effective interaction between universities, research centres and schools, and the participation of professional associations, funding and evaluation agencies, Education Departments and the Ministry of Education, Science, Technology, and Innovation.

ABSTRACT Soil education plays an important role in preventing soil degradation processes by raising awareness among the population about the importance of this non-renewable resource. Using new educational technologies in teaching, such as educational videos and social media, can speed up communication and information. This article aimed to develop educational videos on the topic of erosion, posted on social networks, as a way of popularizing science. Four videos of a maximum of 7 minutes were produced, which were shown in the classroom and on Instagram (@saberessobresolos). In-class promotion reached nine undergraduate and postgraduate classes, totaling an average of 255 students. Metrics used for evaluation were polls and video engagement on the social network. Instagram metrics results indicated, in a period of 49 days, 1615 profiles had accessed the video. There was a reduction in this engagement in other publications, probably due to the variation in time, day of the week, and frequency of posts. The results of the surveys were positive for all the characteristics evaluated, with little disparity among the videos. On a smaller scale, negative feedback was observed, such as: the narration, running time, the translation into Brazilian Sign Language (Libras), and video captions. Approximately 81 % of individuals reported experiencing soil erosion effects, and 59 % had encountered issues as a direct consequence. The evaluation also indicated the videos’ ability to enhance knowledge is above 90 %, largely due to the dynamic and inclusive nature of this pedagogical approach, fostering genuine comprehension of the content, satisfaction in learning, and the ability to engage in meaningful discussions on the subject. Disseminating educational videos through social media ensured the democratization and widespread access to soil education, as it expanded reach and facilitated the exchange of knowledge between universities and society. The project fulfills its mission of producing and popularizing knowledge on soils, expanding scientific dissemination, making it more accessible, and contributing to recognizing the importance of conserving this resource. nonrenewable non renewable resource teaching information networks science produced @saberessobresolos. saberessobresolos @saberessobresolos .
