Python can launch sub-processes that function separately. Using this approach it is possible to create any number of desktop widgets. This resource includes instructions to create two widgets: a simple RSS news reader and an image downloader for Astronomy Picture of the Day. Some additional Python modules must be...

This document looks at a variety of lessons devised by teachers in fourteen Leicester city schools, who took part in a project developing creative and cross-curricular links to practical science.

Supported by European Commission funding, the project supported European schools to raise standards in...

This Catalyst article looks at salt, in particular the process of extracting salt from the sea in the salt factories of Trapani in Sicily. Located on the west coast of the island, the saline (salt ponds) were probably started by the Phoenicians around 3000 years ago. The article also looks at the structure of salt...

This Catalyst article looks at NASA's Mars Curiosity rover, the automated chemistry lab which landed safely on Mars in August 2012. Capable of analysing samples from the planet's surface and atmosphere, the rover will undertake two years of experiments in the hope of discovering even more about our neighbouring...

A Catalyst article about Dolly the sheep which was born in 1996. The scientists who created her claimed she was a ‘clone’ from a female adult sheep. To prove this claim, genetic profiling or fingerprinting was done by another, independent group of scientists. The article explores how this was done and what other...

A Catalyst article about the work of Damian Murphy a music technologist. Acoustics and sound are examined in addition to the physical modelling and acoustics of buildings and environments, both real and virtual.

This Catalyst article is about using computer models which use natural selection to evolve new products. Computers can be used to simulate evolution showing how some species die out and how others evolve and thrive. Products used by humans in everyday activities also evolve and this article describes how their...

A Catalyst article about designing, building and testing a spacecraft. There are thousands of man-made satellites orbiting the Earth. Some are only a few hundred kilometres above the Earth and complete one orbit roughly every 90 minutes. Geostationary satellites are located around 40 000 kilometres from the surface...

This article, from the Association of Teachers of Mathematics (ATM) publication ‘Mathematics Teaching’, and is taken from MT180.

Judith Steven and Kym Scott argue the importance that primary school teachers plan activities for children’s mathematical development out-of-doors. The activities should be...
