Pincelli, M. M.; Brustle, M.; Formichella, M. del C.; Perez-Millán, C.; Palmieri, N.; Otranto, S. – Physics Education, 2020
In this work, an adaptation is developed of the first observation attempted by Galileo to demonstrate the heliocentric hypothesis to be correct. The objective is to enable students in their final year of elementary school to confront by themselves the same contradictory evidence that Galileo confronted during the second decade of the 17th century.…

Hombas, Vassilios – International Journal of Mathematical Education in Science and Technology, 2012
This article shows a generalization of Galileo's "passe-dix" game. The game was born following one of Galileo's [G. Galileo, "Sopra le Scoperte dei Dadi" (Galileo, Opere, Firenze, Barbera, Vol. 8). Translated by E.H. Thorne, 1898, pp. 591-594] explanations on a paradox that occurred in the experiment of tossing three fair "six-sided" dice.…

Arnone, Stefano; Moauro, Francesco; Siccardi, Matteo – Physics Education, 2017
The year 2014 marked the four-hundred-and-fiftieth anniversary of Galileo's birth, making it the perfect occasion to present and illustrate a GeoGebra applet which reproduces some of Galileo's celebrated experiments on the uniformly accelerated motion, as reported on in "Discourses and Mathematical Demonstrations Relating to Two New…

Wiesner, Matthew P. – Physics Teacher, 2015
Every introductory astronomy class encounters Galileo during the course as the first man to systematically study the sky with a telescope. Every Astronomy 101 student meets Galileo as one of the major catalysts behind the shift from the Ptolemaic to the Copernican system and as one of the great minds behind the scientific method. But most of the…

Sirola, Christopher – Physics Teacher, 2019
One of the most consequential inventions of modern times is the telescope. Almost immediately upon turning it to the skies, Galileo made discoveries that altered our perceptions of our place in the cosmos forever: features on the Moon, the rotation of the Sun, the composition of the Milky Way, the phases of Venus, and the four large moons of…

Pierratos, Theodoros; Polatoglou, Hariton M. – Physics Education, 2020
In this work, we propose an interesting combination of the Atwood machine and Galileo's inclined plane to study quantitatively kinematics with a smartphone and the phyphox app. For this purpose, we use the optical stopwatch function, based on the photosensor of the smartphone. The choice of phyphox app has some advantages for presenting the…

Groetsch, C. W. – International Journal of Mathematical Education in Science and Technology, 2012
An aspect of Galileo's classical trajectory that persists in a simple resistance model is noted. The resistive model provides a case study for the classroom analysis of limiting behaviour of an implicitly defined function. (Contains 1 note.)

Machado, Juliana; Braga, Marco Antônio Barbosa – Science & Education, 2016
A characterization of the modelling process in science is proposed for science education, based on Mario Bunge's ideas about the construction of models in science. Galileo's "Dialogues" are analysed as a potentially fruitful starting point to implement strategies aimed at modelling in the classroom in the light of that proposal. It is…

Ponce Campuzano, Juan Carlos; Matthews, Kelly E.; Adams, Peter – International Journal of Mathematical Education in Science and Technology, 2018
In this paper, we report on an experimental activity for discussing the concepts of speed, instantaneous speed and acceleration, generally introduced in first year university courses of calculus or physics. Rather than developing the ideas of calculus and using them to explain these basic concepts for the study of motion, we led 82 first year…

Davidovic, Milena D.; Markovic-Topalovic, Tatjana; Sliško, Josip; Božic, Mirjana – Physics Teacher, 2020
In the same chapter of his book "Opera Geometrica," Torricelli published two discoveries: 1) initial velocity of a jet from a container increases with the square root of the depth of the hole; 2) he drew the pattern of jets from three openings at the wall of a container filled with water to constant level "H" and determined the…

Finocchiaro, Maurice A. – Science & Education, 2011
Galileo's telescopic discoveries of 1609-1612 provided a crucial, although not conclusive, confirmation of the Copernican hypothesis of the earth's motion. In Galileo's approach, the Copernican Revolution required that the geokinetic hypothesis be supported not only with new theoretical arguments but also with new observational evidence; that it…

Cerreta, Pietro – Science & Education, 2014
The Gravity-Powered Calculator is an exhibit of the Exploratorium in San Francisco. It is presented by its American creators as an amazing device that extracts the square roots of numbers, using only the force of gravity. But if you analyze his concept construction one can not help but recall the research of Galileo on falling bodies, the inclined…

Cavicchi, Elizabeth – Interchange: A Quarterly Review of Education, 2011
What do you see in a mirror when not looking at yourself? What goes on as a pendulum swings? Undergraduates in a science class supposed that these behaviors were obvious until their explorations exposed questions with no quick answers. While exploring materials, students researched Galileo, his trial, and its aftermath. Galileo came to life both…

Straulino, S. – Physics Education, 2011
In his "Two New Sciences" Galileo Galilei deals with the strength of objects, discussing how it changes with size. Our daily life offers many examples of effects due to change of dimensions and sometimes the consequences are unintuitive. This subject is really interesting for secondary school students and it can be presented through simple…

Ucke, C.; Schlichting, H. J. – Physics Education, 2017
This relatively rare thermometer has a rather unusual display: lower temperatures are located at the top of the scale, higher ones at the bottom. A sphere on a chain floats in a suitable liquid, sinking at high temperatures when the density of the liquid decreases and rising in the increased density at low temperatures. With reasonable effort and…
