Knurr, Benjamin J.; Hauri, James F. – Journal of Chemical Education, 2020
For the past century, humans have been increasingly dependent on plastics, but have not developed adequate disposal practices. In this lab, students are asked whether burning plastic for energy seems like a reasonable disposal technique. To answer the chemical aspects of this question, students use bomb calorimetry to quantify the combustion…

Kamarainen, Amy; Grotzer, Tina; Thompson, Meredith; Sabey, David; Haag, Brooke – Journal of Biological Education, 2023
Education reform calls for portraying science as a process of inquiry and argumentation grounded in the epistemic traditions of a domain. While experimentation is a core scientific investigation strategy, diverse approaches are represented across different domains of science. Ecosystem scientists use experiments as a core part of their…

Victoria Borish; H. J. Lewandowski – Physical Review Physics Education Research, 2023
Quantum mechanics is a field often considered very mathematical, abstract, and unintuitive. One way some instructors are hoping to help familiarize their students with these complex topics is to have the students see quantum effects in experiments in undergraduate instructional labs. Here, we present results from an interview study about what it…

Midori Tanaka; Toshimichi Shibue – Journal of Chemical Education, 2023
High-resolution mass spectrometry (HRMS) is an analytical technique that is typically used by mass spectrometry experts. However, with recent advancements, it is becoming more accessible to students in organic chemistry laboratories. Still, a significant knowledge gap exists between these experts and students. A straightforward laboratory…
