A statistical graphic from the Gatsby Foundation which demonstrates the chronic shortage of physics teachers across the UK and which looks at the various campaigns to address this shortfall over the past few years.

This video shows the huge range of industries and sectors which students could work in with qualifications in STEM subjects.

This video demonstrates the Coriolis effect. However, explains that much of what we see in terms of rotating water in either the northern or southern hemispheres is mostly due to other angular momentum sources in the body of the water.

An explanation of the Coriolis effect uses a scientific model (thought...

This edition of the Computing at School newsletter contains articles covering:

*Computing in the national curriculum

*Computational thinking in the classroom

This experiment allows you to investigate the boiling point of brine and the melting point of lead using a potentiometer arrangement. An alternative approach using digital voltmeters is also included at the bottom of the sheet.

In this Catalyst article, Mike Follows describes the surprising range of thermometers available to scientists today.

Many physical properties of materials depend on temperature. Thermometers are vital for measuring body temperature. The body's biochemical reactions work best at 37°C and the body is in...
