We propose an apparatus that emulates the experiment used by Geiger and Marsden in 1913 to investigate alpha particles (Rutherford) scattering. Using a widely available fused deposition modelling 3D-printer, we built a compartmented and easily assembled educational instrument. The whole apparatus is composed of a 3D-printed chamber and an…

A Science, Technology, Engineering and Mathematics (STEM) tool is proposed in this manuscript; which consists of an interactive, simple and low-cost computer based simulation and game, with the aim of easing the teaching/learning process regarding the physics concept of projectile motion. The novelty of this proposal relies on the use of a…

This paper describes the use of a tabletop electron microscope in teaching college level physics. The workings and use of an electron microscope encompass many aspects of science, technology, engineering and mathematics (STEM). A sequence of activities was constructed to compliment the instructional material in the physics course of the University…
