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…

Topographic maps are a common form of 3D surface elevation data represented as a 2D display. Despite their use in geoscience courses, many students find learning to effectively read and interpret these maps challenging. Here, we present a tool for teaching topographic map interpretation using 3D printed terrain. The terrain was 3D printed from a…

Experiments involving electrochemical cells are of great pedagogical value for learners of introductory chemistry. This paper discusses an improved experimental kit made from a 24-well cell culture plate and a 3D-printed scaffold. The current design focuses not only on the accuracy of the result but also on the intuitiveness of the wiring work and…

A planetarium is an invaluable tool for teaching introductory astronomy, but one that few astronomy educators have ready access to. Here we describe a do-it-yourself planetarium that can be built with modest funding. There have been other planetarium construction projects described in the literature and online, most of which use cardboard to make…

Today's students are increasingly immersed in a landscape of screens and handheld digital devices through which a good deal of their interactions with the world around them are mediated. Physics educators, meanwhile, continue to rely on traditional human interactions with the physical world, such as sliding down a ramp or throwing a baseball, in…

Introductory chemistry students encounter the concept of hybrid orbitals as a transition from atomic orbitals to molecular bonding. The principal purpose of learning hybridization in the undergraduate curriculum is to impart an understanding of the origins of molecular bonding and geometry. Physical models of both individual hybrid orbitals and…
