Chemistry experiments are challenging for people with vision impairment (VI) as results often rely on visual observations such as a color change. This puts pupils with VI at a disadvantage both in their scientific learning and in their development of broader life skills. In this paper, we describe a simple and low-cost experiment on the adsorption…

In this study, we derived several formulas for the currents induced in a circular loop by a magnet connected to a spring-based simple harmonic oscillation system. In addition, we conducted an experiment for measuring the induced currents and compared the results with the theoretical prediction. It was confirmed that the prediction from the derived…

Science diagrams are an integral part of science because they are an important means of conveying and visualizing abstract science content. In recent years, researchers have demonstrated the educational benefits of encouraging students to draw their own conceptual diagrams, rather than focusing on interpreting diagrams given to them. To help…

A drug discovery project has been successfully implemented in an advanced undergraduate organic chemistry laboratory. In the laboratory, a five-step synthetic sequence is used to prepare five analogues of 13-phenyl-1-tridecanol. These compounds are key precursors in the synthesis of 2-oxo-14-phenyltetradecanes. This class of compounds, isolated…

There have been growing calls for inquiry, a practice-oriented way of engaging students in authentic scientific work, yet research has shown some challenges that might impede inquiry practices in educational settings. In this study, we proposed an approach that blends educational gaming with physical experiments. We developed an educational game,…

This paper describes a student-centered approach to teaching and learning physics in a high school classroom. The teacher designs and uses a 5E learning cycle to teach series and parallel electric circuits. This article provides an example of the implementation of 5E model for a physics lesson to address three-dimensional learning-science and…

A community-engaged learning experiment was developed for an introductory analytical chemistry course at the University of Toronto Scarborough in collaboration with Campus Farm. The experiment introduced students to the application of analytical techniques to studying environmental samples. More specifically, students investigated the potential of…

Experiments involving electrochemical cells are of great pedagogical value for learners of introductory chemistry. This paper discusses an improved experimental kit made from a 24-well cell culture plate and a 3D-printed scaffold. The current design focuses not only on the accuracy of the result but also on the intuitiveness of the wiring work and…

A Maker-oriented experimental course in general chemistry has been created by using digital tools, such as a computer, a pressure sensor, and data processing software, in combination with a new multiple expansion method and laboratory equipment to determine the vapor pressure precisely. In this Maker chemistry experiment, the pressure sensor…

In this guided inquiry experiment, students extract catecholase enzyme from apples to catalyze the oxidation of catechol. They follow the reaction using the UV--vis absorbance of the "p"-benzophenone produced to determine the Michaelis-Menten kinetic parameters. Students make selected experimental choices within a structured framework…

Photochemical synthesis, in which light is used as an indispensable reagent, is recognized as a green technique for organic synthesis and has been paid extensive attention. In this laboratory experiment for chemistry classes, a photoinduced C-C coupling reaction is introduced, which can be conducted under mild conditions at room temperature.…

Based on a publication of Assis, where the most straightforward and oldest motor is described, first constructed by Ampère, a simple experiment is added to demonstrate once again, why published explanations about its principle of operation and especial the kind how Newton's 3rd principle is used has to be rejected. Ampère's description of his…

Transistors are semiconductor devices that form the basis of today's electronic technology. Following the first step of developing a point-contact transistor developed by Walter Brattain and John Bardeen in 1947, the development of the junction transistor by William Shockley in early 1948 opened the way for rapid progress in electronic technology.…

Cosmetic chemistry is a prevalent part of everyday life, but there are very few undergraduate laboratories that explore this topic. Here, we present a laboratory exercise in which students use fizzing bath tablets (better known as "bath bombs") to learn about introductory kinetics. Students created their own bath bombs by combining…

The Michelson interferometer is one of the key experiments in modern physics when it comes to the topic of interference (Box 1). Experiments using interferometry have a high historic relevance as well as uses in current areas of research (quantum erasers, gravitational wave detection) and are used in higher education. Because of the high cost of…
