This series of Marvin and Milo cards include eight simple experiments that can be performed at home that link in to the theme of light, using: - A torch and a bottle to show total internal reflection - A glass of water to make a lens - Milk and water to show the scattering of light - Making a light bulb light up...

A Catalyst article about mobile phones. This article looks at the science behind this popular piece of technology, such as the use of radio waves, aerials and cells. The article also explains how mobile phones are able to use short aerials.

This article is from Catalyst: GCSE Science Review 2005, Volume 16,...

Produced by the Science Museum, this resource sees students working in groups to explore the issues surrounding genetic testing. Students receive a sealed secret box, that contains a chance card. Opening the box represents taking a genetic test. Students have to decide whether they would want to open the box. In...

This video asks people if they believe cell phones can cause cancer.  It then considers the available evidence logically, that is types of radiation emitted by a cell phone (non-ionising) and the power rating to conclude that the radiation should not be harmful. However, recent evidence suggests that heat-shock...

Video from the Big Picture issue on Fat, showing an experiment to discover if we favour fatty foods.

This video demonstrates how applying pressure to ice melts it, yet on removal of the pressure the ice re-freezes.  This is called regelation.

A Catalyst article about Dorothy Hodgkin who was a pioneering scientist, a peace activist, a mother of three and a Nobel Prize winner. The article looks at her life and work in science. She did valuable work as an X-ray crystallographer and in finding the structure of biologically important molecules such as...

Like the Deflection tube investigation this allows A-level students to measure the specific charge for an electron. It provides a step-by-step guide, along with the calculations that are required to find this measurement.

This resource has been provided by Keith Gibbs.

A series of images representing double helix images.

• DNA double helix and sequencing output: molecular model of a DNA double helix showing the individual atoms (apart from hydrogen) as coloured balls. Carbon atoms are in white, oxygen in red, phosporus in purple and nitrogen in blue....

This kit and their associated resources are designed to help teach about double-slit and diffraction patterns.

Before teaching this, students should:

• be familiar with constructive and destructive interference;
• be aware that we get diffraction when a wave travels through a gap;
• ...

Produced by Science & Plants for Schools (SAPS), the investigations suggested in this resource use duckweeds. These seem to be simple plants - small, green, and with no flowers. However, this simplicity makes them ideal experimental organisms for investigations into...

A Catalyst article about Charles Darwin's home and in particular his study which is open to the public. Visiting information is included in the article which puts into context the importance of this room in his work.

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

This Catalyst article looks at how people lived in the past, archaeologists look at the items (artefacts) these cultures left behind. Using chemical analysis of residues in the artefacts an enormous amount of additional information can be gleaned. This article investigates early dairy farming. Analysis of tiny...

From the Microbiology Society, this resource contains information about biofilms. These are communities of microbial cells attached to a surface. For example, the slime lining plugholes and drains or the rough deposit that can coat teeth at the end of the day. The information clearly describes: * What are biofilms...
