A Catalyst article about the Nobel Prize for physics 2009 winner Charles Kao, who developed optical fibre systems and CCDs which are the basis of most of today's long distance telephone systems. Kao also developed tiny solid state lasers which work for years without failing. The article also looks at the bringing...

Linnean Learning wants to see a world where curiosity in the natural world is shared by all young people. We work with young people, teachers, parents and other adults to inspire the next generation to engage with world outside.

Linnean Learning projects are a part of the Linnean Society of London, which...

There are four posters in this resource covering the following areas of the biology curriculum:

• Biodiversity: gives an overview of what biodiversity is, how it is measured and the threats to biodiversity
• Classification: describes the main features of classification and the binomial system of...

For this investigation students will be calculating the density of a liquid (usually water) by using the loaded test tube method.  By adding mass to the test tube, you work out how far it has sunk then by substituting results into an equation, work out the density of the liquid.  This is a good experiment for...

Publishedin 2009 by LSIS, this report describes research undertaken by Newham Sixth Form College. The project aimed to produce a set of strategies and resources in order to develop the literacy of science students to enable them to achieve in A - level Biology. A high proportion of students come from families in...

This literature review, by NFER, sought to address the following research questions:

• What does AfL in science involve?
• What AfL techniques are...

This resource from CAS London is a reference guide to compilers, interpreters and assemblers. It could be used as a revision summary for students or as a reference for questions.

Each issue of the Big Picture is on a different topic in biology and comes with its own sprinkling of ‘fast facts’, fascinating snippets of information on the topic. This booklet brings together the best of the fast facts from the last fourteen issues, sorted into eight themes, for use in project work, as part of...

These learning materials describe ISIS, a particle accelerator facility at the Rutherford Appleton Laboratory. Produced by the Science and Technology Facilities Council (STFC), these resources will help students to:

* Improve their understanding of atoms, molecules, neutrons and muons
* Find out about...

This introduction to the Living in a Materials World CD-ROM describes the work of ISIS, a research centre based at the Science and Technology Facilities Council (STFC) Appleton Rutherford Laboratory.

At ISIS, particle accelerators provide beams of neutrons and muons to enable the structure and dynamics of...

This MEI resource for complex numbers demonstrates loci in the Argand diagram. In the complex plane the horizontal axis are real numbers and on the vertical axis are imaginary numbers.

The excel file uses sliders to alter the position of the point on the plane. The point can be picked up and moved into all...
