Accuracy and precision are measures of experimental error and are fundamental to most chemical analysis laboratory classes. Assessment of accuracy and precision is often based on the comprehension of the results generated by students rather than on the quality of the data generated. This activity focused on developing a chemical analysis…

A physical chemistry lab for undergraduate students described in this report is about applying kinetic models to analyze the spread of COVID-19 in the United States and obtain the reproduction numbers. The susceptible-infectious-recovery (SIR) model and the SIR-vaccinated (SIRV) model are explained to the students and are used to analyze the…

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…

Benchtop NMR spectrometers are now becoming more widely employed in university teaching laboratories. These low-field instruments are increasingly used in reaction monitoring and product purity applications. NMR spectra obtained using these spectrometers (40-80 MHz) tend to suffer from significant overlap of signals when compared to those obtained…

High voltage supplies are often used in physics classes for demonstrations and laboratory work. These devices deliver several thousand volts DC, while limiting the current to a safe level, typically under 5 mA. One issue with these power supplies is their expense, which means schools may not have one. Less expensive homemade units have been…

Raspberry Pi Pico, based on chip RP2040, is an easy-to-use development microcontroller board that can provide flexible input/output functions and meets the teaching needs of basic electronics to first-year university undergraduates. This article presents our blended laboratory design using Raspberry Pi Pico for the course unit Digital Circuits and…

Course-based undergraduate research experience (CURE) exposes an entire class of students to scientific research and is thought to increase students' knowledge retention in science, technology, engineering and mathematics education. Microbial engineering is an interdisciplinary subject that combines science and engineering. We transformed a…

Digital practical work (DPW) has emerged as a highly effective and indispensable component of science education, enhancing and extending traditional laboratory experiences. DPW aims to complement physical laboratory experiments, particularly those that teachers may find challenging to conduct or lack the confidence to perform. In this study, a…

As part of its STEM programming initiatives, Community Boating, Inc., the nation's oldest public sailing organization introduced an "Introduction to Microscopy" course merging principles of scientific investigation with analytical techniques using compound light microscopes. Boston's Charles River provided the environmental setting for…

Allowing students to practice science inquiry in the classroom is fundamental for science education. Students should master investigation skills, promoting their understanding of science concepts. Virtual laboratories have emerged as a powerful interactive tool that can be a suitable alternative to real laboratories, especially when lacking enough…

Developing models, using mathematics, and constructing explanations are three practices essential for science inquiry learning according to education reform efforts, such as the Next Generation Science Standards (NGSS Lead States, 2013). However, students struggle with these intersecting practices, especially when developing and interpreting…

Molecular photochemistry is an integral field in chemistry. Despite this, it is often difficult to demonstrate an effective hands-on experiment that offers a unique opportunity to students to observe photochemistry in action. Although simple laboratory experiments which use a UV-vis wavelength lamp do provide some photochemical information, the…

A laboratory experiment is described in which students carry out immobilization of the enzyme invertase via entrapment in alginate (Ca-alginate) and, accordingly, estimate values for kinetic constants and mass transfer coefficients. Immobilization of enzymes, or confinement thereof to a defined space with retention of most catalytic activity, is…

Coronavirus (COVID-19) disease is an emerging situation that brought challenges to all sectors, including academia and research. Undergraduate and postgraduate students in biochemistry and molecular biology have been affected significantly due to the recent laboratory closures. Experiments have been suspended for long causing extreme stress to the…

This article describes a straightforward approach to deliver an enzyme assay and kinetics laboratory via online delivery methods in the time of COVID-19.
