This visual mathematics project focuses on the beautiful images known as Julia Sets (named after French mathematician Gaston Julia). Students use a repeated iterations to explore the world of complex numbers, writing and amending a relatively complicated Scratch program. 

Edexcel’s GCSE Astronomy syllabus provides an opportunity for students to develop their understanding and enthusiasm for astronomy, as well as to complement and extend the reach of their study of Key Stage Four science, technology, engineering and mathematics (STEM) subjects.

A Catalyst article about Socotra, a small archipelago of four islands in the Indian Ocean off the horn of Africa, belonging to the Republic of Yemen. The islands are becoming famous for their range of animal and plant species and for their use as a natural 'laboratory' where ideas about evolution can be tested. The...

This School Science Review article outlines the Space Academy programme led by the National Space Centre from 2008 to 2011 with the stated goals of harnessing the inspirational contexts of space and climate change to support GCSE, A-level and vocational students in their curriculum studies as well as to enhance...

A Catalyst article describing the species that have had the greatest impact on planet Earth during its billions of years of history. Which come out on top of the 'league table of life'? As hominids have only walked the Earth for part of its existence the article looks at the history of life, from the dawn of...

This Catalyst article looks at the effect exercise has on the body. Poor fitness contributes to poor life expectancy, and inability to exercise reduces quality of life in the ill or aged. Scientists hope to understand the mechanisms which limit 'exercise tolerance' which would contribute to enhanced performance for...

Most people are all too familiar with the idea of animal parasites, including tape worms, ticks and lice. But did you know that plants can also act as parasites, exploiting resources from unwilling hosts? Rather than being rare anomalies, however, there are over 4000 known species of parasitic plants, with...

This resource is a simplified version of part of the Intergovernmental Panel on Climate Change's (IPCC) report in 2021on the evidence for climate change and human activity that drives it. The language used is appropriate for pupils aged 14 to 16 and can be used as a reading comprehension exercise. Pupils have to...

This Catalyst article looks at how plants colonise sandy beaches, producing dune systems and ultimately new land.

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

*Computing in the national curriculum

*Computational thinking in the classroom

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...

This Catalyst article looks at thorium - a heavy element, similar to uranium. Some people think that it could be the nuclear fuel of the future, as it can be used as the fuel in a fission reactor - and it appears to be much safer than uranium.

A Catalyst article about neutrinos. Neutrinos are fundamental particles. They are tiny, a neutrino has a mass about one-millionth of the mass of an electron, and they have no electric charge. This article looks at the detection of these elusive particles which requires the use a giant detector. The one described is...
