The present work aims to know how playfulness, as a teaching technique, is contributing to a better development of modern education and, especially, to improve the learning of the contents treated in the discipline of Chemistry. The methodology used for the elaboration of this work was based on bibliographical research and field research. The latter consisted of a survey of data through the application of a questionnaire, seeking to know the opinions of the students regarding the approach of a content using a playful activity, and to compare the level of understanding acquired by the students with its realisation. The playful activity was developed from easily accessible materials with 22 third-year high school students from a public school in Crateús. From the results obtained with the application of the activity, we realise that the game can substantially assist the teaching and learning process in Chemistry Teaching.
