An educational excursion is a study trip or research trip, in which students leave the school building to develop educational and learning activities in a different environment, usually related to the subject on which the excursion has reason. Thus, for example, an excursion to a museum can be part of the curriculum of the history subject, where the teacher transfers his students to a different environment so that they can make direct contact with the topic to be addressed in class.
Excursions, in general, are excellent educational experiences, as they are efficient ways of establishing knowledge since the student relates the subject studied with the lived experience, which facilitates their understanding of the topic and their fixation of knowledge.
