In teaching the science of the nano world, ball-and-stick molecular models are frequently used as 3D representations of molecules. Unlike a chemical formula, a molecular model allows us to visualise the 3D shape of the molecule and the relative positions of its atoms, the bonds between atoms and why a pair of mirror isomers with the same atoms,…

The nature of light and how it is affected by gravity is discussed. Einstein's prediction of the deflection of light as it passes near the Sun was verified by observations made during the solar eclipse of 1919. Another prediction was that of gravitational redshift, which occurs when light emitted by a star loses energy in the gravitational field…

Early in 2010, a group of year 11 students (age 15-16) studying GCSE (General Certificate of Secondary Education) Astronomy at The Radclyffe School, Oldham, in the UK, teamed up with a similar age group from Tianyi High School, Wuxi City, in China, to undertake a joint astronomy investigation. This article outlines the outcome of the first stage…

Thermal cameras are useful tools for use in scientific investigation and for teaching scientific concepts to students in the classroom. Demonstrations of scientific phenomena can be greatly enhanced visually by the use of this cutting-edge technology. (Contains 7 figures.)

Finding an old notice on a canal towpath inspired a consultation with colleagues and search for evidence in an old book to help people look into how the words and symbols used in the teaching of electricity have evolved, including the apparent oddity of the symbol "I" for current. It is easy to explain that people use the symbol "Q" for what is…

A simple activity using cheap and readily available materials is described that allows students to experience first hand many of the concepts of measurement, uncertainty and graph drawing without laborious measuring or calculation. (Contains 9 figures.)

Pupils ask STEM subject teachers about jobs and careers in science, but where else do they learn about work? This article outlines career-related learning within schools in England alongside other factors that influence pupils' career decisions. The effect of the Education Act 2011 will be to change career learning in schools. The impact on…

Students at age 11 or 12 took a course where scientific skills were taught discretely rather than in an integrated approach alongside scientific knowledge and understanding. There is evidence that this may be a more beneficial approach for developing scientific skills. (Contains 1 figure and 1 table.)

Designing investigative skills sessions for key stage 5 students based on field research in the Ghanaian savannah prompted reflection on the similarities and differences in the ways farmers and students learned about and applied scientific methodology. Circumstantial constraints mean that farmers' experiments were less controlled than those…

A very limited questioning of undergraduate Environmental Science students at the start of their studies suggests the age of the Earth is being successfully taught in high schools. The same cannot be said for the teaching of the structure of the Earth.

The placement of final-year undergraduate students into schools and colleges is becoming increasingly common in higher education as part of outreach, employability and community-building initiatives. This article describes one such initiative at the School of Earth and Environment, University of Leeds, its successes, its challenges and why schools…

Physics is a subject where pupils hold a great number of deeply seated misconceptions. Sound is a prime example, as it requires the visualisation of a form of energy that moves imperceptibly through an invisible medium. This article outlines some of the common misconceptions that pupils hold regarding the nature of sound and how it is transmitted,…

Two groups of year 6 pupils (age 10-11 years) each experienced science practical lessons that were essentially identical but for one difference: one group (theory-led) were told by the teacher what result they should expect, and the other group (hypothetico-deductive) were not. The theory-led group demonstrated experimental bias, recording results…

This article presents a framework for considering teaching intentions relating to literacy within the context of the school science curriculum. It focuses on the provision of learning experiences involving discussion,reading and/or writing and specifically on student-authored podcasting as a "writing-to-learn" activity that can assist young people…

This article describes the design, delivery, evaluation and impact of a CPD course for physics and chemistry teachers. A key aim of the course was to use the context of the James Webb Space Telescope project to inspire teachers and lead to enriched teaching of STEM subjects. (Contains 1 box and 3 figures.)
