Milici, Pietro; Plantevin, Frédérique; Salvi, Massimo – International Journal of Mathematical Education in Science and Technology, 2022
We propose an original machine that traces conics and some transcendental curves (oblique trajectories of confocal conics) by the solution of inverse tangent problems. For such a machine, we also provide the 3D-printable model to be used as an intriguing supplement for geometry, calculus, or ordinary differential equations classes.

Jiro Kondo; Shota Nakamura – Journal of Chemical Education, 2023
The use of molecular models in chemistry and biochemistry classes is very effective in helping students understand covalent bonds and the chemical structure of molecules. However, conventional molecular models cannot represent intermolecular interactions such as hydrogen bonds and electrostatic interactions. Herein, we describe 3D printed…

Jaconiano, Yasmim R.; Goulart, Juliana S.; Barros, José C.; Michel, Ricardo C. – Journal of Food Science Education, 2021
It began in 1869, and today we have 118 elements listed in the Periodic table, thanks to Mendeleev's work. Carbon, hydrogen, oxygen, and nitrogen are elements presented in many organic compounds. Some of them can exhibit photophysical and photochemical properties. Herein, we proposed an easy to make an experiment in chemistry classes to connect…

Mihasan, Marius – Biochemistry and Molecular Biology Education, 2021
The structure and function of biomolecules relationship is the hallmark of biochemistry, molecular biology, and life sciences in general. Physical models of macromolecules give students the possibility to manipulate these structures in three dimensions, developing a sense of spatiality and a better understanding of key aspects such as atom size…

Bernard, Pawel; Mendez, James D. – Biochemistry and Molecular Biology Education, 2020
Development of three-dimensional (3D) printing technology has started a new chapter for in-classroom modeling of chemical molecules. The technology provides the opportunity to design and produce various types of personalized models. However, using classical 3D printers is time consuming, and it is hard to involve students in the modeling process…

Renner, Melissa; Griesbeck, Axel – Journal of Chemical Education, 2020
Due to immense cost reduction and routine commercial availability, 3D printing has become the cutting-edge technology with enormous potential--also for educational and applied chemistry. It opens the opportunity to print custom-made reactors, such as (micro) flow reactors. In addition, 3D-printing technology can simplify chemical reactions, such…

Ionel Popa; Florin Saitis – Journal of Chemical Education, 2022
Proteins are "magical" workers inside our body, as they accomplish most of the cellular functions. Here we report on a novel approach to teach protein folding and unfolding, using magnets and flexible 3D-printed protein structures. To illustrate this physical process, we used colored circular magnets designed for whiteboards, connected…

Haverkamp, Nils; Havemann, Judith; Holz, Christoph; Ubben, Malte; Schlummer, Paul; Pusch, Alexander – Physics Education, 2021
Kundt's tube is a popular experiment commonly used in schools, in which standing sound waves are made visible inside a glass tube. A fine powder is stirred up in areas of high sound particle velocities, so that one can measure the wavelength of the sound waves by examining the patterns created. In this way, the 'invisible' can be made visible.…

Michelle Garcia; Frances A. O'Leary; Daniel J. O'Leary – Journal of Chemical Education, 2023
This report outlines an approach for preparing 5-color 3D printed plastic models of molecular orbitals and electron density surfaces using a hobby-grade 3D printer. Instructions are provided for preparing 3D orbital and electron density surface (EDS) models using solid or mesh representations in ground state and transition state structures. We…

Forringer, Edward Russell – Physics Teacher, 2022
In a 1993 book review, E. Pearlstein asks, "Why don't textbook authors begin their discussion of magnetism by talking about magnets? That's what students have experience with." A similar question can be asked, "Why don't professors have students measure the force between permanent magnets in introductory physics labs?" The…

Methin Intaraprasit; Piyathida Tawornparcha; Pann Veerapong; Taweetham Limpanuparb – Journal of Chemical Education, 2023
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…

Calheiro, L. B.; Freitas, W. P. S.; Martins, C. A.; Goncalves, A. M. B. – Physics Education, 2021
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…

Roy, George J.; Cunningham, Matthew; Rafanan, Kenneth – Mathematics Teacher: Learning and Teaching PK-12, 2023
In this article, the authors explain how they leveraged the popularity of the "Star Wars" franchise to introduce a task steeped in popular culture as a fun way to engage their students in investigating complex mathematics that have real-life connections to careers in toy design and engineering design in general. The authors share various…

Hobbs, Elizabeth; Schisler, Laura; Pressley, Hugh; Smith, Walter – Technology and Engineering Teacher, 2021
Picture students huddled around a 3D printer in a middle school classroom. They gaze at the object being printed, and exclamations of, "Where is that flag from?" "What does that symbol mean?" and "Oh; I didn't think of that!" can be heard. These examples of observation, curiosity, and critical thinking are the elusive…

Flowers, Jim; Rose, Mary Annette – Technology and Engineering Teacher, 2020
New technologies are being developed every day. Many of these may not make it into the curriculum for technology and engineering students. For those that do, there may be quite a delay between the time the technology is introduced at an industrial scale and when the technology is developed at a relatively low cost and small scale needed to…
