The conduction of electricity is an important topic for any basic physics course. Issues of safety often results in teacher demonstration experiments in front of the class or in extremely simple though--for students--not really fascinating (not to say boring) hands on activities for everybody using 1.5 V batteries, cables and light bulbs etc. Here…

This paper deals with what it means to sense and touch a real image formed by a spherical mirror using a proximity sensor commonly utilized in smart phones.

A disco ball is a spherical object covered with small plane mirrors. When light reflects on these mirrors, it is scattered in many directions, producing a novel effect. The mirror globe is usually set to rotate, creating a profusion of moving spots (Fig. 1). In this article, we present a geometrical description of the movement of these spots and…

Contribution: This article aims to explore learner variables that predict the effectiveness of university class using the Havruta method. Background: This article was conducted on 105 learners enrolled in the "General Physics and Experiments 2" class at K University in South Korea. Research Questions: Independent and dependent variables…

This modular, open-framework capstone course delves deeply into the synthesis, separation, and characterization of chiral molecules while teaching critical thinking and writing skills in a research-like setting within a fertile area for discovery. This course has evolved over 30 years and has been in its present form for 5 years at the time of…

In light of COVID-19 in spring 2020, we developed a simple and versatile inquiry-based, laboratory-style active learning colorimetry experiment amenable to at-home quantitative analysis. In this experiment, students acquire an external calibration method using aqueous solutions of a self-selected chromophoric analyte from household products using…

Due to the COVID-19 pandemic, education at all levels has temporarily shifted to remote learning, hobbling an integral component of chemistry courses: the laboratory. The chemistry lab is crucial for developing student engagement and learning with hands-on, relevant experiments in a socially dynamic classroom setting. The transition to remote…

With biochemistry forced to transition to remote-teaching online, the cooperative active learning and problem-solving normally in labs have been limited. With little ability to perform experiments with laboratory equipment, determining how to mimic the qualities integral to these labs in an online environment is necessary. We propose one possible…

Simulations and virtual or remote laboratories are increasingly used in schools. The extent to which individual experimental skills can be acquired when experimenting in digital applications is, however, questionable. This paper focuses on finding multimedia features for digital experiments to support the transfer of measured values from the…

Introduction: In the Baccalaureate, the exact and experimental science subjects demand the development of scientific competence, which in turn requires mastery of theoretical knowledge and practical knowledge, but also motivation and sustained effort for greater involvement and academic performance. Hence the relevance of knowing the motivational…

The "Next Generation Science Standards" ("NGSS") have placed an emphasis on the incorporation of engineering practices into K-12 science instruction. This article details a sequence of physical science lessons that would be part of teaching matter in the second-grade classroom. The goals of these lessons are: (1) to be hands-on…

This work describes a simple talking calorimeter for the visually impaired based on the Arduino Uno without any shield. An electronic interface was designed using a Wheatstone bridge, a thermistor, or an operational amplifier (opamp). The temperature values are communicated by a loudspeaker connected to pulse-width modulation (PWM) digital output…

We present our experience with transferring a four-day photometry and dye-adsorption laboratory experiment to the kitchens of students of Applied Thermodynamics from our degree in "Industrial Chemical Process Engineering". The students designed and built a double-beam photometer using their smartphones and household materials, then…

In this study, we probed high school students' understanding of Einstein's theory of gravity by implementing an approach which mainly consists of two steps: firstly, exposing students to TEs describing the Equivalence Principle; secondly, applying the analogy of parallel lines on a curved surface with the path of two falling balls in a real…

An organic solar cell fabrication kit has been developed for demonstration in both undergraduate teaching classes and high school laboratories to promote the growing field of renewable energy and to facilitate empirical comprehension of solar technology. The laboratory focuses on fabricating organic photovoltaics (solar cells) and testing the…
