This video recaps on the idea that light sent along an optical fibre requires total internal reflection for it to progress along its length. It explains that information is sent as a series of on – off signals.  However, if light rays take different paths they can be modally dispersed, and this can degrade the...

This article from Catalyst looks at aurora borealis caused by the interaction of the solar wind with the Earth's magnetic field. It also explains how satellites are testing thoeires of how this happens. Auroral light emission occurs at roughly 100 km altitude. Energetic electrons in the solar wind cause the...

Salters' Science was a complete teaching programme to provide an applications-led approach to double award science at Key Stage Four. It was followed by 'Science Focus', a Key Stage Three programme to illustrate a similar approach to teaching and learning in science....

A Year Ten module from the Salters’ double award GCSE science course. This module deals with interactions between species in ecosystems. Students are shown how stable conditions lead to a natural balance in populations and how human activities can disturb this balance....

A Year 11 module from the Salters’ Key Stage Four double award gcse science course. This module draws together ideas about chemical bonding and the energy changes associated with bond making and bond breaking. The relationship between type of bonding and the properties...

This is a CPD taster created to give teachers a better understanding of what to expect when joining one of our primary science courses. Below you will find a video and a task for you to do in your own time. Once you have done the activity, ...

Food Science was one of the four topics that featured as a separate area of study in the Nuffield Home Economics course for students aged 14–16. The course was designed to help students understand the scientific principles underlying the practical work they would do in...

The Science Processes and Concepts Exploration (SPACE) project research report on Light was published in 1990 by Liverpool University Press. The SPACE research was conducted at two centres: at the University of Liverpool and King’s College, London, with Wynne Harlen and...

The Science Processes and Concepts Exploration (SPACE) project research report on Materials was published in 1991 by Liverpool University Press. The SPACE research was conducted at two centres: at the University of Liverpool and King’s College, London, with Wynne Harlen and Paul Black as joint directors.
