Sound waves are often studied as part of mechanical waves in the upper-secondary and undergraduate physics curricula. Acoustic levitation is an application of standing-wave phenomena, growing in popularity through the recent adoption of low-cost ultrasound transducers. Nevertheless, acoustic levitation has not yet been included in the standard phen...

There has been a growing realisation that school science curricula do not adequately reflect the revolutionary changes in our scientific understanding of the 20th century. This discrepancy between current school education and our modern scientific understanding has led to calls for the modernisation of the science curriculum. Although there have be...

Nowadays scientific research, supported by technological development, proceeds at an inexorable speed. Thus, technical features could be difficult to understand for many of the population. Therefore, the research for a universal language has now become fundamental. At the same time, in the post-digital era, artistic research approached technology. ...

We designed an inquiry activity to investigate the question ‘How transparent are transparent films and papers?’ Using an easily-replicable set up, we observed the effect of increasing the number of transparent films, thin papers and general papers between a light source and a light sensor. For each material, one sheet was added each time. The amoun...

During the pandemic, traditional final assessments in the form of in-person, timed, invigilated final examinations were not an option. As a result, in the academic years 2020/2021 and 2021/2022, students in the second year Electricity and Magnetism courses at the University of Guelph were asked to complete personalized study guides/portfolios as a ...

For approximately 2400 years BC, carpenters have been using hammers to nail wood. The reason for this method is unclear and evaluations of its effectiveness should not be made without proper research. Therefore, this study aims to develop a force-measuring instrument to analyze the impulsive forces produced during hammer strokes on nails. The measu...

A simple method of demonstrating apparent weightlessness in free fall is described. The Apollo 15 hammer and feather drop experiment can be recreated in the classroom using a book to shield the feather from air resistance. Plastic toys and a feather thrown together in a plastic bottle can be used to recreate an apparent weightless environment close...

This study investigates the application of a Wheatstone bridge, specifically through the utilization of a meter bridge constructed on chart paper using pencil graphite. Employing the Wheatstone bridge principle, this study aims to achieve precise measurements of an unknown resistance. Results indicate an error margin between measured and calculated...

Several public schools and also universities in Brazil have few or none financial resources to acquire certain equipment for teaching physics. Nevertheless, it is extremely important that institutions, schools and universities offer laboratory conditions for the students, mainly in engineering courses, in order to get the first contact with physics...
