Creating pleasant musical sounds by vibrating the strings of musical instruments such as guitars and violins is the result of the type of instrument played as well as the mastery of the player. This article explains the physics of vibrating strings caused either by a bow drawn over them or by being plucked, and provides a simple analysis to…

The formation of waves as used for surfing close to the shore is described and explained, and linked to other wave topics that are covered in school science. Of course, there are differences because the wave activity is influenced by many factors, such as the weather and the shape of the shoreline, which make the wave patterns much more…

Earthbound manifestations of gravity in falling objects are distorted by the large mass and size of the Earth. Movement is also affected by air resistance. This article questions whether an approach based on everyday observations is necessarily the best starting point for introducing the idea of Newtonian gravity. Instead, a theoretical approach…

The bicycle is one of the greatest locomotive machines ever invented. It is also a perfect vehicle for you to teach some of the ideas that are taught in forces topics to 11- to 16-year-olds. In this article we look at some of the ways in which you can use the bicycle and cycling to provide an alternative and engaging context for teaching some of…

The infrared camera, or thermal imaging camera, can be used to complement the teaching of a number of topics in high school science. Here, we provide seven examples of its application in teaching physics, chemistry and biology concepts at high school level. We also discuss its strengths for such applications and provide some pointers for science…

Martin Wagenschein's ideas of prioritising phenomena in making sense of science processes have influenced the German "Lehrkunstdidaktik" (art of teaching) approach. This article sketches a "Lehrkunstdidaktik" teaching unit inspired by Michael Faraday's "Chemical History of a Candle." It shows how primary and lower…

This article is the second of a two-part series that explores science teachers' and their pupils' experiences of using different pedagogical approaches based on understandings of how brains learn. Part 1 (Torrance Jenkins, 2017) focused on the two approaches rooted in cognitive psychology: Cognitive Load Theory (CLT) and Cognitive Acceleration…

This overview is intended to help colleagues achieve successful and satisfying observations using a ripple tank. There are many observations to consider that can effectively illustrate reflection, refraction, interference and diffraction, but the most important consideration is to make every effort to enable students to see the effects we want…

This article examines how students taking a post-compulsory physics course for 16- to 19-year-olds (A-level physics) benefited from a change in pedagogy which meant that they spent more time problem solving in collaborative groups. Video analysis of these collaborative problem-solving sessions revealed that the students improved a number of key…

While on the International Space Station, Tim Peake undertook and recorded video files of experiments suitable for physics teaching coordinated by the National Space Academy. This article describes how the video of these experiments was prepared for use with tracking software. The tracking files of the videos are suitable for use by teachers or…

A key challenge when teaching physics is to equip students with the ability to apply the concepts to real-life situations. Students do not learn by information alone; they are affected by their environment, their social setting, how their body and mind feel and the interactions between these different aspects. This may explain why wild places and…

Science education research has shown that students use causal reasoning, particularly the model "agent--instrument--object," to explain or predict the outcome of many natural situations. Students' reasoning seems to be based on a small set of few intuitive rules. One of these rules quantitatively correlates the outcome of an experiment…

'Best Evidence Science Teaching' (BEST) is a collection of open-access, research-evidence-informed resources for science teaching at 11-14. BEST includes progression toolkits comprising sequenced learning steps, diagnostic questions and response activities. Case studies illustrate how teachers are using BEST resources. Observations and interview…

This article explores some of the common mathematical difficulties that 11- to 16-year-old students experience with respect to their learning of physics. The definition of "understanding" expressed in the article is in the sense of transferability of mathematical skills from topic to topic within physics as well as between the separate…

The historical background to the laws of thermodynamics is explained using examples we can all observe in the world around us, focusing on motorised transport, refrigeration and solar heating. This is not to be considered as an academic article. The purpose is to improve understanding of thermodynamics rather than impart new knowledge, and for…
