This interactive file shows the graphs of functions and the graph of the corresponding reciprocal function. It begins with the graph of a linear function where the gradient and intercept can be changed. The reciprocal is plotted on the same diagram. The next two sheets...

This series of videos, named Recollections, shows how Werner von Siemens, who had an inventive mind and a knack for new technology, went from being a soldier to building a global corporation. It is a good example of how careers can change dramatically and persistence has its rewards.

Purpose: Digital tools have radically changed the way that fieldwork data can be recorded and saved. There is no longer a need for clipboards and pencils in the field, as digital technology can record details of observations, times, location and images within a single app. This data can be saved to an online data...

This article focuses on Laboratory Astrophysics - the recreation of the conditions of space in the laboratory.

The shortage of specialist teachers of mathematics has been a concern for many years and this resource, from the Learning and Skills Improvement Service (LSIS), is designed to help organisations focus upon a plan of action, which will lead to better recruitment and retention of mathematics teachers.

The work suggested in this Nuffield Working with Science unit helps to make students aware of the inevitable need to recycle materials and of the practical and economic difficulties in the way of doing more at the moment.

This magic trick from the Computer Science for Fun (CS4FN) team at QMUL is based on a ‘self-working trick’. It includes a set of instructions which, so long as the commands are followed, works every time. It is, therefore, an algorithm.

The trick involves playing cards – the actual value of the cards is not...

A podcast from the Natural Environment Research Council's (NERC) Planet Earth Online collection. Red squirrels used to be the most common squirrel in Britain. But since the grey squirrel was introduced from the USA as an illegal immigrant in the late 1800s, their numbers have nose-dived.

This is partly...

Students investigate why the moon turns red during a lunar eclipse by exploring refraction, dispersion and the scattering of white light through different media.

Students investigate transport in plants by seeing what happens when flowers are placed in different coloured solutions.

The reduction mill reduces the thickness of a strip of steel using a series of rollers, each roller making the steel slightly thinner. The percentage reduction is constant on each pair of rollers. The mathematics used to calculate the actual reduction is similar to that used when calculating compound interest....

Mathcentre provide these refresher packs covering Algebra, Numeracy, Differentiation and Calculus. They were designed as activities to support students by preparing them, prior to the commencement of their university course, for the mathematical demands of their programmes. The Algebra Refresher booklet is sent out...

This collection of Nuffield Maths resources explores Decision maths. The demand is roughly equivalent to that in GCE A level. The resources include slide shows to introduce the topics, student sheets and teacher notes, as well as other relevant resources.

This ‘Refurbishing a room’ resource is an...

Practical Action have supplied this teacher's pack to challenge students to use their STEM skills to come up with solutions to a problem of water shortage in Sudan. The pack includes a PowerPoint presentation and Teacher Guide so that teachers can outline the problem to their students. The PowerPoint makes...
