Einstein's derivation of special relativity theory (SRT), based on hypothetical reasoning and thought experiments, is regarded as a prime example of physics theory development. In secondary education, the introduction of SRT could provide a great opportunity for students to engage in physics theorizing, but this opportunity is largely being missed…

Materials science research has expanded significantly in recent years; a multidisciplinary field, home to an ever-growing number of chemists. However, our general chemistry degree courses have not changed to reflect the rise in interest in this topic. In this paper, we propose a laboratory experiment for the undergraduate chemistry practical…

Chemistry in water is an emerging field that fulfills the fifth principle of green chemistry: replacing toxic organic solvents with their benign counterparts. Although some pharmaceutical industries have developed and adopted chemistry in water, its implementation in teaching laboratories is still limited. Therefore, we have designed an experiment…

This work presents a homemade multirole 3D-printed modular spectrometer(MPMS), which can be easily assembled like bricks and expanded with several modules to measure different types of spectra, such as UV-vis absorption, fluorescence emission, flame emission/absorption, glow discharge, and even Raman spectra. The spectrometer is designed to be…

Microplastics have been detected in most ecosystems around the world. They affect the environment and organisms in it, including humans and possibly their health. Hence, the analysis of microplastic occurrence in the environment is highly relevant. However, there are only a few practical and easy-to-implement methods published for school use, and…

The rate of the sonochemiluminescence reaction of luminol in alkaline medium can be increased in the presence of carbon tetrachloride, chloroform, and bromoform. The presence of the latter activators enhances the light emission, to allow studying the kinetics of this reaction in a 4-h laboratory session using a mobile phone camera as a detector…

A two-component undergraduate laboratory experience has been developed by students in a senior level capstone course. The first component is a 3 h laboratory experience dedicated to the rapid synthesis of a metal-organic framework (MOF-808) in aqueous solution using readily available reagents and equipment. During the second component, MOF-808 was…

Catalysis is an essential concept in chemistry, playing a key role in industrial processes. Catalysis has been considered to be challenging not only for university students to comprehend but also for the teachers. In this Laboratory Experiment, we have described a simple activity for demonstrating the concept of catalysis using thread-based…

A Unit Operations Laboratory (UOL) is fundamental to undergraduate chemical engineering education. This article discusses a new course structure for the University of Kansas UOL and details for three new experiments covering the fundamentals of vapor-liquid equilibrium, fluid mechanics, and kinetics. Students apply knowledge from these courses as…

Chemical reactions far from equilibrium can exhibit oscillatory behavior. Full understanding of this phenomenon is outside of the school curriculum. However, the importance of such processes in life sciences and peculiar spatial and temporal patterns accompanying the reactions can attract the attention of IB Diploma science students. They will…

The laboratory is a complex environment where the three levels of the chemistry triplet coincide. As the laboratory environment places a large demand on the working memory of students, cognitive load theory can address overload which causes barriers to learning. Breaking down barriers requires iterative phases of analysis/exploration,…

Many studies have reported various interventions to increase critical thinking, but very few studies have examined the impact of learning in classrooms and laboratories. This study aimed to find a learning pattern (practice to theory or theory to practice) in improving students' critical thinking skills (CTs). Pre and posttest nonequivalent group…

In introductory physics laboratory instruction, students often expect to confirm or demonstrate textbook physics concepts. This expectation is largely undesirable: labs that emphasize confirmation of textbook physics concepts are generally unsuccessful at teaching those concepts and even in contexts that do not emphasize confirmation, such…

A research-style laboratory experiment composed of the synthesis of MOF-74 materials, related structural characterization, and the cutting-edge application of electrocatalytic oxygen evolution reaction (OER) has been designed toward advanced undergraduates at East China University of Technology (ECUT). The desired monometallic MOF-74 (Ni-MOF-74…

This study aims to showcase an experiment for introductory physics students that quantitatively describes the relationship between gas pressure, volume, and temperature. For this purpose, an Arduino Uno Microcontroller and BMP180 pressure sensor are used. The BMP180 can also measure temperature, so another temperature sensor is not needed.…
