A new method to determine a ternary phase diagram of benzene-acetic acid-water system is provided to upper-division undergraduate students. The partially miscible liquid phase region can be accurately constructed using isothermal titration microcalorimetry (ITC). Compared with the traditional visual method, ITC can provide precise data and more…

A laboratory class was developed and evaluated to illustrate the synthesis of metal nanoclusters (NCs) and to explain their photoluminescence properties for the case of silver. The described experiment employs a synthetic protocol that consists of two sequential phases in a single reaction pot: the reduction of silver ions into plasmonic silver…

In this article, we describe a fun and engaging card game called Speed Eleusis that teaches the process of scientific discovery and publication, including such practices as replication and retraction. Much like the traditional game of Eleusis and its variant Eleusis Express, this game involves students competing to model a pattern displayed in a…

As quantum information science and technology (QIST) is becoming more prevalent and occurring not only in research labs but also in industry, many educators are considering how best to incorporate learning about quantum mechanics into various levels of education. Although much of the focus has been on quantum concepts in nonlab courses, current…

Flow cytometry has become an important tool in the fields of veterinary, medicine, and biological sciences in general. However, in the introductory and even in advanced university degree courses, students do not have many opportunities to be in contact with this type of technology. This situation motivated us to design a simple and inexpensive…

Efforts to promote disciplinary literacy can help students integrate knowledge with ways of doing and being within disciplinary settings. Yet, effectively facilitating disciplinary literacy, even within an upper-level undergraduate physics course like the one studied here, is surprisingly hard. This article qualitatively analyzes an instructor's…

Students' recognition of the common procedural mistakes in the chemistry laboratory was examined in this study. Data were collected from 49 undergraduates studying Science Teaching. A video in which a student is purposefully making common procedural mistakes was shown to the students, and they were asked to recognize the mistakes. A Written…

During the COVID-19 pandemic and subsequent lockdown, both schools and universities faced significant challenges in moving teaching from an in-situ setting to a remote one, this included laboratory experiments. This paper presents an experiment developed to use a phone's in built pressure sensor, common to most smart phones. By using this sensor…

The value of experiential lab work can be measured by its ability to transform a student's self-identity related to science, technology, engineering and mathematics (STEM). Successful experiences help students shed notions of self-incompatibility with STEM and can often motivate a research career as they develop as a scientist. However, students…

Development and evaluation of a teaching-learning activity in 4th year Forensic Physics course of Degree in Criminology was based on different combinations of a virtual laboratory and a research laboratory as teaching spaces. Students explored in detail the components and functioning of an electron microscope using both an online suite of…

Many high school students learn about nutrient cycling during biology, environmental science, and agriculture classes. These lessons often focus on soil and plants, and nutrient cycling is usually taught independently from climate change. Scientists know that animals, including fish, can have strong effects on nutrient cycling (i.e., nitrogen and…

Paper Laboratory Notebooks (PLNs) have been used for centuries to document and archive the thoughts and work of inventors, scientists, students, and engineers. PLNs are the first formal means of scientific communication we teach our students and, in turn, a student's first training on cultivating and expressing scientific thinking. In the science…

In 2022, a subset of the Human Anatomy and Physiology Society (HAPS) Curriculum & Instruction Committee administered the third offering of the HAPS lab survey. This survey included a three-part framework of (1) demographics, (2) lab activities and learning outcomes, and, (3) the impact of a global pandemic on instruction. Here we report on…

As data science and instrumentation become key practices in common careers ranging from medicine to agriscience, chemistry as a core introductory course must introduce such topics to students early and at an accessible level. Advanced data acquisition and data science generally require expensive precision instrumentation and massive computation,…

An integrated inorganic chemistry laboratory experience focusing on heterogeneous electrocatalysis with nickel (Ni)- and cobalt (Co)-based electrocatalysts is designed for upper-division, major-level chemistry students. In this laboratory, students will be guided through the fabrication of an indium tin oxide (ITO)-coated glass working electrode,…
