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 article is from Catalyst: GCSE Science Review 2006, Volume 17, Issue 1...

This activity is based on work being carried out at The University of Oxford. A team is using laser-light to create tabletop supernovas to understand the origins of magnetic fields in our universe.

Students will act...

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...

This article, from the Association of Teachers of Mathematics (ATM) publication ‘Mathematics Teaching’, and is taken from MT231.

Jenni Back, Colin Foster, Jo Tomalin, John Mason, Malcolm Swan and Anne Watson set out to resolve the issue of ‘Tasks and their place in mathematics teaching and learning’ by ‘...

This School Science Review article attempts to summarise the good, bad and (occasionally) ugly aspects of teaching astronomy in UK schools. It covers the most common problems reported by teachers when asked about covering the astronomy/space topics in school. Particular focus is given to the GCSE Astronomy...

This Catalyst article investigates teixobactin, which scientists are developing as a new approach to tackling bacterial diseases to overcome the problem of antibiotic resistance.

This Catalyst article looks at how our knowledge of the human genome has increased greatly during the last 10 years, and genome sequencing techniques have become much faster. On 26th June 2000 it was announced that scientists had completed a first draft of the human genome, the DNA instructions for making a human...

A Catalyst article exploring the testing of new medicines to see if they are safe for people to take. The effects on cells of a potential new drug are investigated using tissue cultures of human or animal cells. Some tissue cultures use fresh tissue samples, but most come from well-established laboratory cell...

Published by the Wellcome Trust, the ‘Big Picture’ explores issues around biology and medicine.​

This Catalyst article looks at the noble gases (Group 0 or 8 in the periodic table) which are almost inert. This article shows how they were discovered through the use of fractional distillation and looks at their chemical and physical properties.

This article is from Catalyst: GCSE Science Review 2011,...

This Catalyst article investigates how humans can misjudge the weights of small dense objects and large, light objects and how their perception of weight is easily fooled.

The article is from Catalyst: Secondary Science Review 2014, Volume 24, Issue 3.

A Catalyst article about deciding right from wrong in biology. Modern science raises many ethical questions. How these questions can be answered either ethically or by coming to a personal decision is discussed. How ethical frameworks can be used to address ethical questions is applied to the case of genetically...
