Tangible teaching aids can provide a valuable supplement to traditional textbook-based learning of fundamental STEM concepts. 3D-printed templates detailing the construction of simple parallel and series circuits were incorporated into the lesson plans for 6th-grade introductory physics. Aiming to introduce the concepts of junction and loop rules…

This work shows the redesign of an elemental experience based on the Helmholtz resonator using 3D printing. A Helmholtz resonator is based on a volume and at least one opening that can include a tube or not. The air column inside the tube can be considered the mass of the system, whereas the volume represents the system's stiffness. Due to these…

In this paper, we present the details of the development of a smartphone spectrometer for education using a 3D printer and characterized the performance by comparison with a paper craft spectrometer. The optical design and the narrow slit used in the build resulted in the formation of accurate images of the slit on the image sensor leading to a…
