This toolkit from Plus magazine and Arctic Survey Education explores statistical aspects of the expedition, including the 'spin' that can be put on statistical evidence to make it sound positive or negative, and methods to predict future trends in Arctic climate change.

The whole toolkit can be downloaded...

Stephanie Kwolek invented the tough polymer Kevlar, used in protective clothing and developed a method for demonstrating the production of nylon in the classroom which is still used today.

This guide, for more advanced users of LINUX, shows how BASH scripts can be used for operations on strings and for arithmetical operations. The syntax for BASH is clearly explained.

A useful handbook for setting up a student-led STEM club, with exemplars from three schools.

It is increasingly recognised that giving students opportunities to act as ambassadors and mentors for STEM subjects outside of school can be of great benefit to the individual, their institution, and to the broader...

A Catalyst article about the inner surface of lungs, which is coated with surfactant, allowing oxygen to enter the bloodstream. When babies are born very prematurely they can lack this surfactant, and this can make it very difficult for them to breathe. This is called Respiratory Distress Syndrome (RDS). This...

This Catalyst article features an activity to explore the science behind creating earthquake-proof buildings and the impact of structure stabilisation.

A Catalyst article about the many uses of superconductors. The article looks at what the 1700 magnets at the Large Hadron Collider and power cables in Detroit have in common. Both use superconductors - materials which, when cooled below a certain temperature, lose all their electrical resistance, and display some...

This Catalyst article investigates x-rays. X-rays are used in security scanning and medical diagnosis. Efforts are always being made to reduce the hazard of working with these electromagnetic rays.

This activity follows on from a previous graphics surface project. Previously a single graphics surface was created - this Python program uses multiple surfaces to build more complex graphics and to create effective animations.

Students are encouraged to experiment with the behaviour of the program, and to...

A Catalyst article about the problems of badgers transmitting tuberculosis to cattle, but is a cull of badgers a solution to the problem? When cattle are found to be suffering from tuberculosis, a disease which can be passed onto humans, they are routinely slaughtered. It is known that badgers can transmit the...

A Catalyst article about Tim Berners-Lee, the founder of the World Wide Web. The article looks at the difference between the internet and the web and what is required to create a web that links computer users from around the world.

This Catalyst article explores how microbes communicate and how, by growing two different microbes together, it is possible to discover new substances which may be useful in medicine. Microbial communication happens by small bioactive molecules which the cells release into and receive from the environment. In this...
