I10-R316-article-432622023-12-01T15:10:46Z Measurement of atmospheric pressure with simple elements in class Medición de la presión atmosférica con elementos sencillos en clase Bigliani, Juan Cruz Experimental activity Pressure measurement Curiosity Everyday objects Actividad experimental Medición de presión Curiosidad Elementos cotidianos During the Physics I classes, a series of attractive experiments were included with the aim of capturing the attention of the students, motivating them in the study of physics and helping them build significant knowledge. Based on this experience with the students, this paper relates a practical activity that can be implemented during a Hydrostatics class or as a laboratory activity. The activity is about measuring atmospheric pressure using a syringe and some other everyday objects. Covering the tip of the syringe, a bottle is hung from the stem and filled until the stem begins to descend at a constant speed. Once this is achieved, the mass of water used and the section of the syringe are measured, and the atmospheric pressure is calculated. Then some modifications are made in the way of proceeding to improve the precision of the measurements, and with these results are achieved with a very acceptable uncertainty considering the elements used. At the end of the course, a survey was carried out and 88% of the students who made comments about the classes highlighted the experiments as a positive experience with which a better understanding of the topics developed is achieved. Durante el dictado de clases de Física I, se incluyeron una serie de experimentos atractivos con el objetivo de captar la atención de los estudiantes, motivarlos en el estudio de la física y ayudarlos a construir conocimientos significativos. En función de esta experiencia con los estudiantes, en este trabajo, se relata una actividad práctica que puede ser implementada al dictar una clase de Hidrostática o como actividad de laboratorio. La actividad trata sobre la medición de la presión atmosférica utilizando una jeringa y algunos otros elementos cotidianos. Tapando el pico de la jeringa, se cuelga del vástago una botella que se va llenando hasta que el vástago comienza a bajar a velocidad constante. Logrado esto, se mide la masa de agua utilizada y la sección de la jeringa, y se calcula la presión atmosférica. Luego se hacen algunas modificaciones en la forma de proceder para mejorar la precisión de las mediciones, y con esto se consiguen resultados con una incertidumbre muy aceptable considerando los elementos utilizados. Al final del cursado se realizó una encuesta y el 88 % de los estudiantes que realizaron comentarios sobre las clases resaltaron los experimentos como una experiencia positiva con la que se logra una mejor comprensión de los temas desarrollados.
