These animations, from the Wellcome Trust, explore DNA structure, function and analysis. They explain the biological processes that transcribe and translate the genetic code to produce proteins. Animations also illustrate how the processes used to sequence DNA have developed to allow genomes to be analysed at a...

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...

Activities in this resource aim to:

• celebrate the achievement of completing the Human Genome project in 2003
• show the relevance of genome sequencing today
• explain the methods used for DNA sequencing, including the illumina method of rapid sequencing and the shotgun sequencing

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 article is from Catalyst: GCSE Science Review 2007, Volume 17, Issue 3.

This Mathematics Matters case study, from the Institute of Mathematics and its Applications, looks at how mathematical models try to understand the causes of rogue waves. These huge waves appear without warning, towering high over ships and oil rigs. Traditional mathematical models could not predict the occurrence...

Published by the Wellcome Trust in January 2011, this report provides the findings from the final stage of the evaluation of the Darwin Education Initiative. It includes the findings from follow-up interviews with case study schools which explored the continued use of the Great Plant Hunt and Survival Rivals...

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...

This collection of Nuffield Maths resources explores Data Analysis. The demand is roughly equivalent to that in GCE A level. 

This collection of Nuffield Maths resources explores Data Handling. The demand is roughly equivalent to that in Higher Level GCSE and Level 2 Functional Mathematics.

This resource, aimed at lower ability Key Stage 4 students, introduces the concept of data compression, specifically Run Length Encoding. Students are asked to use an online tool to convert names into binary (ASCII), this binary data is then subjected to Run Length Encoding and encoded binary compared to the...

Using a spreadsheet as a grid of 'pixels', this computing activity teachers how 1's and 0's can store image data. The classroom exercises use images with increasing pixel resolution, looking at how this affects the clarity of the image. Moving from black-and-white images, the students then use grids of colour...

In this resource, the students are asked to look at various aspects of data security. In part this covers cyber security but it also looks at data integrity and ensuring that users data does not become corrupt through various means. There are a variety of activities provided, and all of the necessary resources are...
