Double-slit interference is a difficult phenomenon for students to grasp in an introductory physics course. A thorough understanding of constructive and destructive interference is critical, but even with such an understanding, visualizing exactly how an interference pattern is formed by light passing through two slits can still be a challenge for…

Writing and argumentation are critical to both professional physics and physics education. They are both necessary to the practices of professional science like paper writing and peer review, and are increasingly emphasized in science education standards and best practices. Despite this, the skill of making an extended argument in writing is often…

This chapter provides some elements that may be useful for teacher educators who wish to promote critical analysis in physics. Firstly, it is argued that conducting a critical analysis is useful for any text, whether highly debatable or not, in order to maximise its comprehension. It is suggested that you can give the students both a classic…

Argumentation as a scientific practice has largely been examined along an epistemic and/or dialogic perspective in science education research. Both perspectives have sidelined the use of real material objects that are indispensable for scientists to construct arguments about the natural world. To address this gap, this article investigates how…

This work presents the design of an inexpensive electronic system to measure water temperature and generate an experimental data set used to verify the fitting between experimental and theoretical curves of a water-cooling process. The cooling constant is computed with three different theoretical methods to check their efficiency and this approach…

Light spectrum dispersion is an exciting subject in science because of its beautiful atmospheric colour phenomenon which attracts students. However, to see the phenomenon is not easy since it needs a spectrometer, which is commonly expensive. Therefore, the present study aims to describe a low-cost spectrometer for investigating lighting spectrum…

Air pollution is one of our day's significant reasons for human health problems and affects every community throughout the world. Monitoring air pollution is a key aspect of raising awareness and pollution mitigation approaches followed by different nations. This paper targets to develop a low-cost Internet of things-based embedded system to…

The flight of a quadcopter drone, readily available as a toy, is analyzed using simple physics concepts. A smartphone with built-in accelerometer and gyroscope was attached to the drone to register the accelerations and angular velocities along the three spatial axis while the drone is taking off, landing or rotating. The vertical speed, the…

The paper introduces an electronic device named 'Blinker', which is suitable for laboratory work on topics related to electric current and resistance, as it allows the visualization of electric current. The Blinker is well suited for all levels of education if the activities are carefully selected. However, despite other devices used for measuring…

The current pandemic era demands distance learning, including physics experiments on the topic of optics. One of the optical phenomena that needs to be explained in optic courses is fluorescence. This study offers a simple home experiment regarding the application of fluorescence, namely to identify the purity of olive oil using simple…

We outline the basic theory behind white light interferometry and the workings of a typical light interferometer microscope. We study WLI images obtained for rough and smooth chrome steel spheres to illustrate the principle that curved rough surfaces can be imaged with such a device as long as the surface roughness is kept within certain limits.

Teaching and learning introductory thermodynamics has drawn considerable research attention over the last two decades, especially in several disciplines of higher education. Under particular investigation is the First Law of Thermodynamics (FLT), which offers an expression of energy conservation in thermodynamic systems, as the evidence shows that…

We present a simple and affordable method for making a surface electrodynamic trap for microparticles. The principles of electrodynamic trapping of charged particles are discussed and step-by-step instructions on how to make a surface trap are given. In addition to the electrodynamic trap implementation and operation process, options for its…

When teaching a general education introductory astronomy course that includes a mathematics prerequisite, it is important to convey that formulas and equations physically represent properties of actual objects and processes that occur that can actually be observed. Students with varying comfort levels with mathematics often need to be convinced…

Gender disparities in retention in pathways to science continue to vary widely by course. Undergraduates intending to study prehealth and premedicine often represent a majority of students enrolled in introductory science courses, contribute to a large number of eventual science degree earners, and are a population that typically includes a high…
