In this paper, a study of different authors who show how they have applied the gamified methodology in teaching and the conclusions obtained is carried out. After reviewing these investigations, an intervention proposal is carried out to implement in the subject of Biology and Geology in the course of 1st year of Bachillerato to deal with block 6 in relation to nutrition and the digestive system of animals through the use of a gamified methodology. The implementation of this proposal in class aims to enhance the intrinsic motivation of students and improve their academic performance. In addition, the proposed activities are intended to stimulate the active participation of students and create a collaborative environment in the classroom. In conclusion, it is intended to demonstrate that meaningful learning environments can be built using a game-based methodology, thus improving the attitude of students towards the study of science, compared to traditional methodologies.
