The French horn is used to introduce the three basic properties of periodic waves: amplitude, frequency, and waveform. These features relate to the perceptual characteristics of loudness, pitch, and timbre encountered in everyday language. Visualizations are provided in the form of oscilloscope screenshots, spectrograms, and Fourier spectra to…

One of the core functions of explanation is to support prediction and generalization. However, some explanations license a broader range of predictions than others. For instance, an explanation about biology could be presented as applying to a specific case (e.g., "this bear") or more generally across "all animals." The current…

Teaching about drawbridges allows students to apply skills they have learned in math and science, while also being creative with design and the use of available materials. Students can be exposed to current and ancient designs. Today's drawbridges are beginning to look their age and are in need of updating and modernization. New bridges are being…

The study of buoyancy becomes very interesting when we measure the apparent weight of the body and the liquid vessel weight. In this paper, we propose an experimental apparatus that measures both the forces mentioned before as a function of the depth that a cylinder is sunk into the water. It is done using two load cells connected to an Arduino.…

This article discusses, at a simple level, the dynamics of the wheel-rail interface, which is fundamental to the stability of rail vehicles. The physics underlying this topic deserves to be better known by physicists and physics students, as it underpins such an important part of our technological infrastructure

The 1969 version of "The Italian Job" is used as context for teaching turning forces and introducing or enhancing the understanding of equilibrium and Newton's Third Law of Motion. A Harrington Legionnaire coach is used as the getaway vehicle for a gold heist and the film ends on a genuine cliffhanger, with the rear half of the coach…

This study investigates the modelling conceptualisation of secondary school students in two situations related to particle dynamics: pendulum's motion and horizontal motion. We performed in-depth clinical interviews with secondary school students (N = 10). Participants' ideas about properties which are not 'given' in empirical observations were…

Ongoing changes in mental and personal characteristics of the modern child initiate the updating of means and forms of education. And they, in their turn, update methodological techniques and approaches to the use of methods during the math class. The source of updating methodological techniques may be the principles used when solving scientific…

Linguistic diversity in many schools is high such that science teachers face complex issues regarding appropriate ways of mediating social and academic language in multilingual classrooms. The relationship between these aspects and the task of teaching science (i.e., pedagogy) remains a mystery to many teachers. This paper provides a narrative and…

Evolutionary evidence is important scientific background for appreciating the theory of evolution. We describe a STEAM-based lesson plan that uses paleontological drawings and a modern evolutionary database to explore and understand fossil, morphological, and molecular evidence. Together, with a focus on arthropods and the Cambrian explosion,…

Science appears to be coming under increasing pressure in parts of society and the media, with an increase in 'fake news' and less regard for 'experts'. If this is to be combatted, it is important that students develop a good understanding of both the big conceptual ideas of science and the nature of science itself. This understanding will mean…

This study aims to investigate textbook tasks in the Norwegian school subject Natural sciences and the views of science that the tasks mediate to the pupils. Natural science is an interdisciplinary subject taught in Years 1-11 that includes chemistry, physics, biology and parts of the geosciences. We conducted a qualitative content analysis of…

The authors conducted a qualitative content analysis of the 400 National Science Teachers Association Outstanding Science Trade Books for Students K-12 from 2010-2017 selected for their instructional usefulness in science classrooms. The authors examined these expert-recommended science trade books to better understand their design and to identify…

Research on nature of science (NOS) has confirmed that students' understanding of NOS is best achieved by explicitly considering NOS a cognitive learning expectation and providing opportunities to reflect on it. However, little has been discussed on how to design and use tasks enhancing students' NOS understanding. In an attempt to fill this gap,…

The phenomenon of lateral inversion is explored in this question. If a clock is viewed in a plane mirror, will the motion be clockwise or anticlockwise?
