A 4-week mini-project is proposed for an experimental Physical Chemistry course applied in Food Science training. Activities include preparation of beet extract for the extraction of betanins and analysis of the kinetics of betanins in thermal degradation at three temperatures (60, 70, and 80 ºC). In addition to developing common laboratory…

Biochemistry textbooks often provide a disconnected, highly mathematical, and decontextualized treatment of thermodynamic and kinetic principles, which renders topics like protein folding difficult to teach. This is concerning given that graduates entering careers, like the pharmaceutical industry, must be able to apply such knowledge and related…

Laboratory experiences are a key and integral part of the chemistry degree that are intended to provide the students the necessary training for laboratory work and improve their scientific reasoning/research abilities and their understanding of the uncertainty in experimental measurements. Despite the unquestionable capacity of hands-on laboratory…

This paper describes ten simple thermal imaging experiments designed primarily for upper secondary students, but usable with younger pupils as well. The author's primary motivation was to come up with a meaningful use for a thermal imaging camera even if the teacher only has a short time to work with it--in the extreme case, only one lesson in…

The development, testing, and classroom implementation of a low-cost, reproducible, desktop sized, highly visual double-pipe heat exchanger are presented. Quantitative measurements with the module reveal its usefulness for demonstrating basic and advanced convective heat transfer theory while worksheet-guided inquiries promote student engagement.…

In 2019 and 2020, third-year chemical engineering majors completed a concept inventory at the beginning and end of the semester in their thermodynamics course. Midway through spring semester of 2020, the course switched to emergency remote instruction, replacing hands-on inquiry-based laboratory activities (IBLAs) with short videos. Analysis of…

Augmented reality (AR) has the potential to fundamentally transform science education by making learning of abstract science ideas tangible and engaging. However, little is known about how students interacted with AR technologies and how these interactions may affect learning performance in science laboratories. This study examined high school…

After many years of confusion, thermal performance of sleeping bags has now been quantified and unified using expensive test techniques. Based on Newton's law of cooling, we present a simple inexpensive test and model to check manufacturers' claims on the temperature performance of a range of modern sleeping bags.

Although students take courses in transport phenomena and thermodynamics, they probably do not ask whether these two subjects are related. Here we give an answer to that question. Specifically we give relationships between the equations of change for total energy, internal energy, and entropy of transport phenomena and key equations of equilibrium…

In this work we discuss the intricacies of a simulation using the MS Excel spreadsheet that allows to study in detail the process of heat transfer between two reservoirs at different temperatures through a conducting rod when heat losses are neglected. The proposed physical model computes the time dependence of the reservoir temperatures and…

One of the obstacles that occur in Chemistry learning is low student motivation due to monotonous media. Another thing that currently becomes an obstacle is the COVID-19 pandemic which limits face-to-face learning. However, Chemistry practicum learning in the laboratory is difficult to carry out at students' homes. The purpose of the study is to…

Pupils often find the concepts of heat and temperature difficult to understand and differentiate. The authors believe that an image-to-writing approach can help pupils learn these two abstract concepts -- an approach that uses a series of guided enquiry activities involving heat and temperature. The basic premise is that pupils produce images to…

Within the self-regulated learning literature, motivation is considered to be an essential feature of students' self-regulatory processes. Additionally, task affect (i.e., personal objectives and task value) is thought to influence students' self-regulatory processes; insufficient task affect may lead to failures to self-regulate effectively. In a…

Synthesis and characterization of nanomaterials yields opportunities for instruction of related topics in solution chemistry and materials science, as well as spectroscopy connecting to band theory, the "particle in a box" quantum mechanical model, and thermodynamics. In collaboration with an undergraduate research assistant, we have…

Thermodynamics challenges teachers and learners. Its pervasiveness about nature, mathematical abstractness, nonnumerical relations, and complexity in applications can inhibit understanding and usage, especially by undergraduates. Perspectives are given about these obstacles, and some suggestions are made to enhance comprehension of the discipline.
