The results of an educational project aimed at promoting the development of critical thinking and promote interest in experimental sciences in High Schools and College students is presented. In this paper, we made a compilation of several activities, which ways of integrating information technology and communication (ICT) in various experiments of...

Cuando se deja caer una barra que pivotea por una de sus puntas, el extremo libre, bajo ciertas condiciones, cae con una aceleración vertical mayor que g. Esta es una demostración sorprendente que se conoce desde hace tiempo. En este trabajo presentamos un experimento simple que permite medir con precisión el movimiento de caída del extremo libre y...

En este trabajo se propone un conjunto de actividades susceptibles de realizarse en el aula, que permiten estudiar y “descubrir” leyes de escala presentes en diversos sistemas. El objetivo es desarrollar actividades de investigación aplicables en la enseñanza de la física y ciencias naturales de las escuelas medias, utilizando elementos de bajo cos...

The sound card of a PC is used as a data acquisition system to study the characteristics of the propagation andreflection of sound pulses in open and closed cylindrical tubes of different lengths. From the analysis of the phases ofthe reflected pulses relative to the incident pulse it is possible to explore the difference between the reflection in...

Here we study the kinematics of rigid bodies that roll down an inclined plane without slipping. This work is divided intwo parts. Our objective is to study how, for a given angle of inclination of the plane, the mass distribution of the bodyaffects its acceleration. To carry out this study we make use of a digital camera in video mode. The experime...

We present a simple and inexpensive experiment that illustrates how a digital camera or WebCam can be used in thelaboratory to carry out quantitative studies on the motion of a body in two dimensions. In particular, here we studiedthe case of projectile motion in two dimensions, when the effect of friction with the air is negligible and when it is...

The present study analyzes the shock wave phenomena using a digital camera and an application of this concept tomeasure the speed of a supersonic jet using videos from Youtube. We determined the speed of the plane by measuringthe aperture of the cone of the shock wave. When the plane exceeds the speed of sound, a conical cloud is clearlyvisible on...

AbstractIn this work we discuss classical geometrical models that allow us to estimate the distances from the Earth to theMoon, the Sun, and the diameters of the Sun and the Moon in relation to the Earth diameter. We also indicate how toobtain the distance from the Sun to the rest of the planets and the need of elliptical orbits for the planets. Ou...
