This video begins with the mnemonics Very furry lambs and Cute furry lambs.

Using a model of a railway carriage (its length, x and time taken to travel, t) the equation for velocity (v = ^x/_t) is derived.  Equating the length of the carriage to wavelength, λ and time to the period, T the...

This Catalyst article looks at X-ray free electron lasers that generate intense beams of X-rays and are used to reveal the structure of complex molecules.

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

*Computing in the national curriculum

*Computational thinking in the classroom

This experiment allows you to investigate the boiling point of brine and the melting point of lead using a potentiometer arrangement. An alternative approach using digital voltmeters is also included at the bottom of the sheet.

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 Unilever Laboratory Experiment, published in 1970, describes the analysis of fluorescers from soap and soapless detergent powders. The procedure describes how the fluorescers can be extracted from the product, separated by thin layer chromatography techniques, and made visible by exposing the chromatograms to...

Published by the Wellcome Trust, the 'Big Picture' explores issues around biology and medicine. The human brain may be the most complex structure in the universe.

The brain is so powerful that it is attempting to...

This resource from Susan Wall contains a number of open–ended questions which explore understanding and allow a variety of approaches.

Each question is easily accessible but can be extended to make a more complex problem. Students are required to justify their answer and, where possible, generalise their...

In this section you can see learners engaged in activities that promote mathematical discussion and explore your role in managing discussion with your own learners.

Introduction
Discussion is an excellent way for learners to rehearse their understanding and to learn from each other. Teachers often say...

Thinking about learning focusses on five aspects of effective practice that teachers and trainers have found to be particularly important in promoting successful learning: questioning, discussion, using misconceptions, assessment and meeting the needs of all learners. Selecting each of these aspects will allow you...
