Di-deoxy sequencing is a way to determine the order of bases (A,C,G and T) in a piece of DNA. A set of 4 lanes (one for each base) is needed to sequence any given piece of DNA. Wherever a black
band appears in a particular lane that base is present. By reading off the order of bands across the four lanes the...

This 3D video journeys into the human cell revealing a chromosome’s centromere.

This Catalyst article discusses the science behind motivation in sport. Self-efficacy has been shown to have a strong influence on performance in athletes, with those who believe in themselves generally attaining more success than those who are plagued with self-doubt. Psychologists are developing theories to...

A case study from the Engineering and Physical Sciences Research Council (EPSRC) which describes a new simple and convenient way for people with diabetes to check their own sugar levels. 'Smart' tattoos enable constant monitoring of glucose levels without the need for blood samples. EPSRC is a part of the Research...

This video lists 10 facts about great white sharks.

This Association for Science Education (ASE) publication about plant tissue culture was developed in association with Unilever plc. At the time Unilever was a major producer of consumer goods: mainly food and drinks, detergents and toilet preparations.

This Association for Science Education (ASE) publication about the industrial use of micro-organisms was developed in association with Nipa Laboratories Ltd. At the time, the company was recognised throughout the world as a specialist in the production of microbiocides...

A Catalyst article about Darwin's beetle collection - an early step in his scientific career. Beetle-collecting was something of a craze in the early 19th century; at the same time, scientific understanding of these creatures grew rapidly. The well illustrated article looks at Darwin's work in this field.

This poster, from the Science and Technology Facilities Council, celebrates 100 years since two scientists in the UK pioneered a technique for crystallography.

Crystallography uses x-rays to create a diffraction pattern to examine the atomic structure of crystals. The poster explains Bragg’s Law, which...

Produced in 2003, these performance descriptors for chemistry science subjects at AS and A2 levels were written to indicate the level of attainment characteristic of grades A/B and E/U boundary candidates across a series of assessment objectives. It was intended that they should be interpreted in relation to the...

Produced in 2007, these performance descriptors for science subjects at AS and A2 levels were written to indicate the level of attainment characteristic of grades A/B and E/U boundary candidates across a series of assessment objectives. It was intended that they should be interpreted in relation to the content...

Published in 2009 by LSIS, this report describes an action research project by Kingston Maurward College. The project compared a traditional ‘lecturer centred’ approach to physiology teaching with a student-led approach using data loggers to compare both learner retention and engagement between these methods. The...

This set of subject criteria were produced by the Qualifications and Curriculum Authority in 2006 for Awarding Bodies to produce AS and A level science subject specifications, in biology, chemistry, physics, psychology, geology, electronics and environmental science.

AS and A level subject criteria are...
