Every day we deal with chemistry in various forms, but sometimes we don't see that. An example is biosensors that help us to evaluate health conditions, monitor environmental pollution and ensure food freshness. The most well known (and most widely sold) is the biosensor for blood glucose measurement, used every day by people with diabetes.…

An introduction to the noble gases and chemical bonding via Lewis theory and the octet rule are common inclusions in secondary school curricula. However, the usual approach may lead to misconceptions and difficulties when valence bond (VB) theory and valence shell electron pair repulsion (VSEPR) theory are taught at a later pre-university stage.…

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…

This article describes the results of a study into students' experiences of independent research project work in science. Independent research projects are projects in which students are supervised (usually by a teacher, scientist or both) to work independently on a scientific problem or question over an extended period. We collected data from 39…

Students make and test a seemingly impossible material made from ice and sawdust that had been developed for possible emergency use during the Second World War. It was open to the students to be creative with their methods of testing the viability of such a material. The thought of making a battleship from ice that would gradually melt seems…

This article describes how a class of year 9 (age 13-14) students engaged in a research-informed and negotiated action science project to address socio-scientific issues. The project was informed by the 'STEPWISE' curriculum framework. Evidence suggests that students benefited from collaborative problem-solving, developing confidence, motivation…

Genetics forms a major part of A-level biology specifications in the UK for 16- to 18-yearolds. Research has identified several reasons why learning genetics is hard. However, research has not investigated whether examiner reports are useful for identifying difficult genetics concepts for students. This research explored the extent to which…

This study applied an unconventional use of past examination papers by converting questions into hands-on experiments for students. Students in an experimental group were engaged in use of those experiments while the remainder attended conventional lectures with written practice. The results reflect that the experimental group positively improved…

"The Language of Mathematics in Science" is an ASE/Nuffield project aimed at supporting teachers of 11-16 science in the use of mathematical ideas in the science curriculum. Two publications have been produced. This article focuses on the first of these, "The Language of Mathematics in Science: A Guide for Teachers of 11-16…

The article describes a science activity designed to increase students' knowledge and awareness of the spread of COVID-19. It helps students achieve scientific literacy through improving their views about the nature of science and their argumentation skills. It also promotes students' engagement in scientific practices such as modelling,…

This article summarises the practical requirements for new science A-levels in biology, chemistry and physics for first teaching from September 2015. It discusses the background to how the new approach was reached and how OCR has seen this taking shape in our assessment models. The opportunities presented by this new approach to practical…

The physics curriculum is usually defined by content but this does not provide students with an authentic experience of the subject. An alternative is that physics is defined more as a way of thinking and this idea is explored in terms of the purposes of physics education, assessment and the relationship of the subject with other disciplines. A…

Raising the profile of physics is particularly important in girls' schools. Here we describe a range of astronomical activities and observations that we have used, which we hope will inspire teachers at other schools to do likewise.

From September 2015, schools in England will be teaching new A-level science specifications that have been developed by examination boards to encompass new higher levels of demand developed by the Department for Education. Integral to these new specifications is a radical change to the contribution of practical science to the A-level grade of the…

People use many different products made from plastics every day. But conventional plastics such as polyvinyl chloride (PVC) do not always have a good reputation in society at large. Bioplastics such as thermoplastic starch (TPS) promise to be better alternatives but are they really better than conventional plastics? This article presents a new…
