Over time, it was understood that glass is electrified by friction and the small bodies are electrified by induction at a distance. This simple experiment was later incorporated into the first electrostatic machines and soon became one of the classic electrostatic experiments in physics textbooks. In this article, we show that there may be more to this historical demonstration experiment than meets the eye, and that repeating this experiment in a school laboratory could be a terribly complicated affair.","PeriodicalId":39773,"journal":{"name":"Physics Education","volume":"60 2","pages":"025018-025018"},"PeriodicalIF":0.0,"publicationDate":"2025-02-21","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"147903673","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The online survey was open to all practising educators and technicians in Scotland’s secondary schools and further education colleges. Descriptive statistics were used to analyse the results, alongside basic thematic analysis of text responses. The results indicate a decline in practical work in the classroom but suggests this is not due to the COVID-19 pandemic. Instead, cost and availability of equipment alongside a perceived lack of time for experimental work are cited as the major difficulties. The resulting recommendations are improvements to the curriculum and support for educators to develop best practice.","PeriodicalId":39773,"journal":{"name":"Physics Education","volume":"59 6","pages":"065022-065022"},"PeriodicalIF":0.0,"publicationDate":"2024-10-18","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"147892751","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

However, these phenomena are explicable without assuming that the speed of electromagnetic waves changes. The actual speed does not alter in various media but is customarily assumed to do so as this facilitates straight-forward calculations and allows easily understood explanations to be advanced. An underlying account of transmission and refraction at the level of individual atoms is presented in which the speed of electromagnetic waves remains constant.","PeriodicalId":39773,"journal":{"name":"Physics Education","volume":"6 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2024-09-16","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142254133","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

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 phenomena investigated in undergraduate and upper-secondary physics courses. The objective of this Frontline is to introduce acoustic levitation in the classroom. This is done with LeviLab, a low-cost and easy-to-use experiment, accompanied by three hands-on procedures (LeviLabs): modifying the cavity length, visually representing standing waves with multiple levitated particles, and a tactile experience by moving a single particle between nodes. The first procedure yields the most accurate speed of sound measurements, while the second and third offer valuable qualitative insights into standing wave properties. This work demonstrates the educational potential of acoustic levitation to investigate sound waves. It aims to make the phenomenon accessible as a learning resource for upper-secondary and undergraduate physics laboratories by providing engaging hands-on experiences for qualitative and quantitative exploration.","PeriodicalId":39773,"journal":{"name":"Physics Education","volume":"201 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2024-09-15","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142254134","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

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 been attempts to introduce topics of Einsteinian physics (i.e. quantum physics and relativity) to school education, often at the secondary level, we still lack a seamless curriculum in which modern science concepts are gradually introduced in primary and middle schools. Guided by the Model of Educational Reconstruction and following a mixed-methods research design, the Einstein-First project aims to address this gap. Einstein-First has developed and implemented an Einsteinian curriculum from Years 3–10 (students aged 7–16) that resolves the disconnect between science in schools and modern scientific understanding. This paper presents the concepts and rationale for the Einstein-First learning approach, as well as a summary of learning outcomes in six Australian schools with 315 students across Years 3–10. Our generally positive findings lay the foundation for informed curriculum development and school education that provides all students with awareness and appreciation of the fundamental concepts that underpin the technologies of the modern world.","PeriodicalId":39773,"journal":{"name":"Physics Education","volume":"108 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2024-09-12","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142254135","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

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. The link between art and science has very ancient roots but in recent years has reached a complete overlap. For example, this is the case of the sonification process, which consists of the use of un-speech audio to transmit information. In this paper, we present Gravitational Music, an installation able to translate the physical phenomenon of gravitational waves propagation into sound, by exploiting an artistic approach. Gravitational Music is an efficient teaching tool that can be used for both school and adult purposes to simplify the complex language of science.","PeriodicalId":39773,"journal":{"name":"Physics Education","volume":"3 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2024-09-09","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142225245","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

For each material, one sheet was added each time. The amount of light received was collected and graphed by a data logger. Our findings show that, as the number of sheets increases, the amount of light received at the receiver decreases. The general paper and thin paper stacks took 4 sheets and 10 sheets respectively to achieve negligible light transmittance. The transparent film stack did not achieve negligible light transmittance, but successive addition of sheets did lower transmittance. Evidently, transparent films are not perfectly transparent. Transparency (and opacity) is not a binary condition, but rather a continuum based on boundary conditions. The inquiry activity developed through this study, which investigates a spectrum of transparency in films and papers, may be useful for students to appreciate the spectral nature of the transparency concept across different materials.","PeriodicalId":39773,"journal":{"name":"Physics Education","volume":"17 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2024-09-08","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142197991","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

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 measurement process is based on the laws of conservation of momentum and mechanical energy and the work-energy principle. The apparatus was constructed using a PVC pipe fitted with a rope pulley and load. The measurements were taken by dropping the mass onto nails embedded in the wooden specimens of keruing, teak, mahogany, and pine. The findings demonstrate that the impulsive force involved in driving nails into wood remains constant. This force is not influenced by the speed of the hammer swing, but rather by the wood’s level of hardness and penetration depth. Using harder wood results in a greater impulsive force, therefore, driving nails becomes more efficient in securing them into the wood.","PeriodicalId":39773,"journal":{"name":"Physics Education","volume":"26 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2024-09-05","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142197994","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
