MóviLab (Moving Lab) was an educational strategy developed at Universidad Industrial de Santander, Colombia, to promote chemistry and science among schoolchildren and teenagers from far rural areas of the Santurbán moor in Colombia during the COVID-19 pandemic. The strategy consisted of designing a kit with chemistry experiments that could be done…

Vera, Fernando Luna; Chalapud, Marcelo Guancha; Viveros, Ingrid Castillo; Medina, Edgar Alexander Vasquez – Journal of Chemical Education, 2018
In this paper, we report an experiment intended as a tool to introduce chemistry and materials science students to several chemical concepts through the determination of the best experimental conditions for the formation of calcium oxide (lime) from a source of high content of calcium carbonate (eggshells). Thermal gravimetric analysis (TGA),…

Ladino, Luis A.; Rondón, Hermilda S. – Physics Education, 2018
The purpose of this paper is to present and discuss an alternative solution to an experimental problem given to high school students in the XXII Ibero-American Physics Olympiad held by Colombia this year. From the measurements of electric current and potential difference across a small tungsten filament lamp students should find the dimensions of…

Torres, Sergio; Powers, Judith L. – Science Scope, 2009
In the exciting, "out of this world" activity described here, students measure the Earth using meter sticks while measuring their shadows in two distant locations. To obtain the size of the Earth, students discover the connection between the measurements of the shadows and a model of the spherical Earth following the method developed by…
