Estudio de las relaciones establecidas entre la radiación y la materia por los estudiantes de grado quinto de primaria de la Institución Educativa Luis Henríquez

Abstract

This research shows the ideas about the relationships between radiation and matter established by the fifth-grade students of the Luis Henríquez educational institution. For this, three activities called “Challenges” were designed in which the phenomenon that reveals different relationships between radiation and matter was studied. Likewise, for each challenge, an interaction phenomenon between radiation and matter was chosen, with an independent context. On the one hand, the first challenge focuses on the photoelectric effect from the construction of a solar car; while in the second challenge the photomorphogenesis from the cultivation of bean plants was addressed and in the third challenge, the study of the physical-chemical changes of the photographic paper from the construction of a pinhole camera and the taking of photographs was proposed. According to this, the technique used was the content analysis that allowed categorizing the communications made by the students. As a result, in the first challenge the categories relationships of movement, the transformation of energy and source of energy were elucidated; in the second challenge, growth relationships and vital functions; and in the third, relationships on the physical and/or chemical changes of the photographic paper and the nature of the photon.
