Schmidt, Jonas; Huber, Tim; Mu¨ssig, Jo¨rg – Journal of Chemical Education, 2022
The knowledge of the mechanical properties of polymers and other materials is essential for several tasks in the field of materials science, like component design and material development. The tensile test is one method of determining many of the material's most defining mechanical characteristics. However, the teaching of laboratory experiments…

Bozzo, Giacomo; Michelini, Marisa; Bonanno, Assunta; Stefanel, Alberto – EURASIA Journal of Mathematics, Science and Technology Education, 2022
We report a research-based proposal on electromagnetic induction within the theoretical framework of the Model of Educational Reconstruction. The proposal is based on a sequence of inquiry-based experimental activities centered on hands-on materials and "Real-Time" quantitative experiments, through which students explore the…

Bouquet, F.; Creutzer, G.; Dorsel, D.; Vince, J.; Bobroff, J. – Physics Education, 2022
Using smartphones in experimental physics teaching offers many advantages in terms of engagement, pedagogy and flexibility. But it presents drawbacks such as possibly endangering the device and also facing the heterogeneity of available sensors on different smartphones. We present a low-cost alternative that preserves the advantages of…

Thy, Savrin; Iwayama, Tsutomu – Physics Education, 2022
Viscous and Coulomb's friction combined contribute to the damping of a pendulum; however, they are usually treated as a silo effect. In this study, we investigate the combination of viscous and Coulomb damping in compound pendulum oscillation, employing two modern instruments that are cheap and handy to quantify the experiments, which are video…

Preisler, Vanessa; Shume, Esayas; Talbot, Jean – Physics Teacher, 2022
Due to the COVID-19 pandemic, in the spring of 2020 many physics programs were forced to quickly transition all of their classes and laboratories to a completely online learning environment. The need for simple and engaging remote physics laboratories became apparent. One relatively low-cost remote lab system is Macmillan's iOLab device. This…

Yamamoto, Tomokazu; Kamiyama, Shinichi; Tanaka, Tatsuya; Yamaguchi, Etsuji – Journal of Baltic Science Education, 2022
In science education, the improvement in students' ability to construct arguments at the primary school level has been reported. Although these studies have identified difficulties in arguments written by primary school students, they do not indicate areas that require improvement in teaching methods. This study aims to explore the possibility of…

Mananghaya, Michael Rivera; Yu, Dennis – Physics Education, 2022
A low-cost simple one-dimensional spring-mass system was constructed to investigate damped oscillations. The suspended mass in the system can move freely inside a cylinder containing a fluid. It provides an in-depth experience for demonstrating various concepts under oscillations. It can be used to probe the magnitude of damping forces in liquids…

Mei Zhang; Wangmin Hu; Wenjing Liu; Chang Lei; Jun Guo; Hongcai Shang; Junling Hou – Journal of Chemical Education, 2022
Interdisciplinary experiments within chemistry are very important for the improvements in the overall quality of the education received by students. In this work, we describe an interdisciplinary experiment that was successfully completed by undergraduate students. This training integrates multiple disciplines including natural product medicinal…

Shirley Lin; Marianne E. Burnett; Melonie A. Teichert – Journal of Chemical Education, 2022
Acid-base titration concepts and experiments are ubiquitous, yet challenging, aspects of the general chemistry curriculum. Most general chemistry courses include at least one acid-base titration laboratory experiment, though the focus is often on determining the concentration, pK[subscript a], or molar mass of an analyte rather than on the details…

Ani Nvehr Davis; Stephan Georgiev Michaelov; Clayton Joshua Rogers; Leighann Rose Weber; Brycelyn Marie Boardman; Gretchen Marie Peters – Journal of Chemical Education, 2022
Polymer chemistry is an important subject in the undergraduate chemistry curriculum. It is required for ACS-certified degrees and significantly connects to real world issues like the plastic waste crisis. While some concepts of polymer chemistry can be incorporated into lecture courses, students' understanding of material properties and…

Ryan M. Steinert; Micah E. Heikes; Jeremy T. Mitchell-Koch; Gary A. Baker; Katie R. Mitchell-Koch – Journal of Chemical Education, 2022
Three direct complexometric titration methods for bismuth subsalicylate determination in over-the-counter stomach relief caplets and liquids are presented, as well as a UV-vis assay, for use in student laboratories. The main difference between titration methods is the choice of indicator; either xylenol orange (XO), pyrocatechol violet (PV), or…

Schweitzer, Julie; Merad, Souhila; Schrodj, Gautier; Gall, Florence Bally-Le; Vonna, Laurent – Journal of Chemical Education, 2019
A laboratory experiment for the determination of the cross-linking density of silicone elastomers is described on the basis of swelling experiments and mechanical tests. In the experiment, the macroscopic swelling and mechanical behaviors of the elastomers were discussed as a function of the cross-linking density, which can be easily controlled by…
