The manufacture of metal alloys is ubiquitous, yet infrequently discussed in high school coursework as concepts related to them are often too complex or abstract for beginning science students. However, earlier introduction to metallurgy in classroom settings could promote interest in practical applications of chemistry, physics, and geology due…

Light rays refract when passing through pockets of transparent fluids with different indices of refraction such as ordinary air pockets of varying temperature. This phenomenon makes night stars twinkle, distorts views above hot asphalt roads and hot barbeque grills, and provides an opportunity for visualizing the normally invisible movement of…

To further the study of learning in the context of immersive virtual technologies, this systematic literature review addressed the following research questions: 'How is self-efficacy being studied in immersive virtual learning environments?' 'What kinds of self-efficacy findings have been made in immersive virtual learning environments?' The…

Classifying, naming, and identifying insects have been complicated topics among science teachers and students. This problem is due to the highly technical collection protocols, safekeeping procedures, the unavailability of appropriate learning resources, and the closure of school laboratories and facilities due to the COVID-19 pandemic. Using the…

In this article, a low-cost, simple, and rapid fabrication of paper-based analytical devices (PADs) using a wax screen-printing method is reported here. The acid-base reaction is implemented in the simple PADs to demonstrate to students the chemistry concept of a limiting reagent. When a fixed concentration of base reacts with a gradually…

Home-based biology experiments (HBEs) are practical learning activities that allow students to perform safe and relevant experiments at home. Motivated by the need to innovate teaching approaches in science education due to the COVID-19 pandemic, this study was conducted to determine the effects of home-based biology experiments (HBEs) on their…

The transfer of electrical energy without any electric leads or cables is not only a modern subject of research, but the technology has already found its way into our daily lives. Especially in consumer electronics a lot of applications are commercially available, mostly non-contact charging applications for toothbrushes, mobile phones, etc. On…

Traditionally, laboratory practice aims to establish schemas learned by students in theoretical courses through concrete experiences. However, access to laboratories might not always be available to students. Therefore, it is advantageous to diversify the tools that students could use to train practical skills. This technology report describes the…

Inquiry practices can be integrated into various settings that differ in terms of their constraints and hence in the scope and depth of the practices that students experience. Key policy papers suggest implementing a gradual learning sequence for inquiry practices so that students' learning experiences in more constrained settings can serve them…

Video analysis is carried out for one-dimensional motion and collision experiments using Tracker. Physical variables, i.e. displacement, time, and velocity, can be deducted from the analysis and allows one to connect them to the equation of motion and energy conservation. Corresponding equations of motions are given without neglecting the effect…

Metals enable numerous physiological processes ranging from respiration to nitrogen fixation. However, the role of metals in biology and biocatalysis is not appreciated by the general public. This lack of knowledge around biological metals can lead to misinformation, especially regarding vaccines and health products. Here, we present a series of…

Research has identified several students' misinterpretations of the principles of the photoelectric effect (PE). Students cannot interpret the formula using the graph's context despite the linear dependence inherited in it. Many studies pointed out that the graphical representation of kinetic energy of the ejected electrons versus frequency of…

1000 Future Scientists (1000FSc) is a university extension project developed at the Department of Chemistry in Federal University of Minas Gerais (UFMG). Conducted by the Higher Education Administrative Technicians and Professors, it presents the university to the community by proposing an engaging experience for elementary and high school…

This study presents an experimental method that illustrates and quantifies the Doppler-effect phenomenon. Two stages of the experimental process were carried out. First, a simplified ripple tank was used to depict the Doppler effect, and the whole experiment was recorded by a digital camera. Second, video analyses of the recorded experiment were…

In Vietnam, nuclear physics is a fundamental part of the national curriculum for physics. However, due to a lack of experimental apparatus (detectors, radioactive sources, etc) at most of the schools, the majority of students do not have opportunities to experience the phenomena behind the concepts. Moreover, safety is another major concern when…
