For many students, the first--and sometimes only--chance to look through a microscope is in high school biology class, where they observe plant and animal cells up close. Even in college, few students use a microscope for a subject other than biology. Thus, it can be a surprise to learn that microscopes are a primary tool used to understand the…

This lab experiment uses [superscript 31]P NMR spectroscopy of biomolecules to determine pK[subscript a] values and the binding energies of metal/biomolecule complexes. Solutions of adenosine nucleotides are prepared, and a series of [superscript 31]P NMR spectra are collected as a function of pH and in the absence and presence of magnesium or…

pH determination is an essential experiment in many chemistry laboratories. It requires a potentiometric instrument with extremely low input bias current to accurately measure the voltage between a pH sensing electrode and a reference electrode. In this technology report, we propose an open-source potentiometric instrument for pH determination…

In hydrostatics, pressure measurement with U-gauges and their relationship to density is a well-known experiment. Very little is studied or experimented with the dynamics of the movement of a liquid in a U-tube probably due to its theoretical complexity but, after all, it is a simple damped oscillating system. In this paper we present a relatively…

This laboratory experiment utilizes an exploration of the storage stability of beer to introduce basic aspects of electron-paramagnetic-resonance (EPR) spectroscopy. Radicals formed upon aerobic forced-aging of beer samples are established by using a spin-trap. The students are introduced to basic principles of EPR spectroscopy and food and…

This two-part laboratory experiment is concerned with investigating key aspects of the Suzuki-- Miyaura cross-coupling reaction. The first part of this experiment utilizes high-throughput experimentation techniques to reinforce, explore, and extend fundamental concepts that are presented in the classroom. In contrast, the second part employs…

The MicRoboCop project introduces chemistry students to the concepts and protocols of synthetic biology. MicRoboCop is a biosensor that has been designed for unique applications in forensic chemistry. The lab is carried out in collaboration with an instructor teaching a genetics course. Students in the biology course synthesize biosensors using…

Lactase is the enzyme responsible for the digestion of the disaccharide lactose, and deficiency in this enzyme causes the prevalent medical condition lactose intolerance. Management of lactose intolerance can be achieved through the administration of lactase supplements. Lactase is an appropriate platform for advanced enzymatic study because its…

For a variety of reasons, understanding oxidation-reduction (redox) reactions can be challenging for introductory chemistry students. To provide an experiential foundation for students to learn redox concepts, we developed a laboratory experiment that frames redox reactions as a simulated murder mystery. In this experiment, permanganate, which…

In this study, it was aimed to investigate the effects of microscope simulation software on prospective science teachers' laboratory achievements, microscope use, laboratory reports and views on microscope which was prepared for general biology laboratory. The case study design was adopted for the research. The participants were 49 science teacher…

The study of vibration in uniform beams provides physics teachers with a platform by which a broad range of physics vibration-related topics can be explored without expensive and specialized equipment. This paper presents two laboratory exercises related to lateral beam vibrations. These exercises use beam theory coupled with free sound-analysis…

In this third and final manuscript from the Human Anatomy and Physiology Society (HAPS) 2022 Lab Survey we document the efforts of Human Anatomy and Physiology (A&P) educators in response to the COVID-19 global pandemic. Institutional, instructional, and student demographics, and laboratory activities and learning outcomes were the focus of…

Astronomy, a captivating field that draws upon science, mathematics, and engineering, has traditionally relied on visual representations to convey the wonders of the cosmos. While this approach effectively engages the sighted population, the use of imagery can exclude individuals with blindness or visual impairment (B/VI). Astronomical research is…

Purpose: This study aims to investigate patterns of information use among undergraduate engineers as they progress through their academic programs. The primary objective was to discern how second and fourth-year students differ in their use of different types of information while performing specific tasks, namely, conducting labs, composing…

This study explores the moderating role of aesthetics and information quality on the technological acceptance of augmented reality. A technology acceptance model with the following variables was used: perceived ease of use, perceived usefulness, attitude towards using, and behavioural intention to use. Analysis was conducted by using structural…
