Thermochromic paint can be made in the laboratory and used for temperature sensing by observation of colour changes. This can be illustrated by an improved method of showing comparative conductivity of heat by different materials, and an amusing method of indicating approximate temperatures of liquids in drinking glasses. The fabric Lycra, used to…

If a person were to observe my classroom when I taught high school physics, he or she would find the traditional labs with the lectures, notes, and problems to solve that enhanced understanding. As I became more skilled in my profession, I promoted inquiry and critical thinking skills. However, the necessity was never obvious to me, nor was I ever…

Young's experiment is hailed as a milestone in ushering a new understanding of the wave nature of light and is even taught at the high school level. Unfortunately, even the most cursory presentation of the subject of diffraction becomes confusing. The theory and equations based on Fresnel's work appear arcane and incomprehensible to a high school…

Physical principles are involved in almost any aspect of cooking. Here we analyse the specific process of baking pizzas, deriving in simple terms the baking times for two different situations: for a brick oven in a pizzeria and a modern metallic oven at home. Our study is based on fundamental thermodynamic principles relevant to the cooking…

For more than 10 years, I had taught Kepler's laws and the law of universal gravity without a corresponding experiment. I sometimes remember how these topics were difficult for me in my high school days to understand. At that time, I thought that one of the reasons for my difficulty was that these phenomena cannot be visualized using physical…

Undergraduate lab design balances several factors: 1) simple experiments connected with learning objectives, 2) experiments sufficiently accurate for comparisons between theory and measurements without gaps when students ascribe discrepancies to confounding factors (imperfect simplifying assumptions, measurement uncertainties, and "human…

Magnetism is traditionally taught within the subject of electromagnetism at the undergraduate and graduate levels in physics courses, with the goal of establishing a solid foundation of the underlying physical mechanisms before advancing to more specialized topics. Oftentimes, a laboratory component of these courses involves practical, hands-on…

The program team operating an NSF Noyce Master Teacher program has been building a conceptual framework for developing teacher leaders. The program has focused its efforts on a group of 16 chemistry and physics teachers in Southeast high-needs schools. The conceptual framework is based on the view that teacher leaders are those individuals who…

Demonstrations of physics phenomena via relatively simple devices and toys have been around for a long time. Because of the pedagogical value of demonstrations, this journal and other periodicals have published papers on the subject of classroom demonstrations including those related to fluid mechanics. Four new, low-cost apparatuses that…

The internal sensors in smartphones for their advanced add-in functions have also paved the way for these gadgets becoming multifunctional tools in elementary experimental physics. For instance, the acceleration sensor has been used to analyze free-falling motion and to study the oscillations of a spring-mass system. The ambient light sensor on…

The introductory physics classroom has long educated students about the properties of the atom and the nucleus. But absent from these lessons has been an informed discussion of magnetic resonance imaging (MRI) and its parent science nuclear magnetic resonance (NMR). Physics teachers should not miss the opportunity to instruct upon this highly…

The relevance of physics is an active line of inquiry within the physics education research (PER) community. Many studies have shown that physics instruction typically negatively impacts students' sense of the relevance of physics to their lives. Irrespective of students' beliefs, physics is communicated as being relevant through policy…

The Moroccan Ministry of Education has recently implemented a multilingual programme, called 'language alternation' (LA). The programme aims at improving students' foreign language (FL) proficiency level and promoting plurilingualism by using French, English, and Spanish, for the teaching of math, physics and life and earth sciences at the…

Content-language integration has been perceived to be an effective approach in second and foreign language learning. However, it can be challenging to implement in content classes, especially in science classrooms. Researchers have suggested using tasks and games to help design diverse opportunities for language and content learning; in…

This paper explores the integration of STEM activities in teaching and learning, emphasizing the importance of innovative pedagogical approaches in effectively introducing theoretical concepts, such as variables and functions, and merging them with practical applications. Drawing on existing literature, this study investigates the integration of…
