This Economic and Social Research Council (ESRC) school briefing looks at the effectiveness of advertising and whether it really is necessary for advertisers to use very thin models to sell their products. Counter to this view, research shows that women are just as likely to buy a product if the model is of average...

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.

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...

A PISA in Focus study published in 2012 from the OECD (Organisation for Economic Co-operation and Development), looks at whether students perform better in science if they are encouraged to participate in extracurricular activities, such as field trips and science projects. Most countries (22 of 31 OECD countries)...

The oceans are become more acidic. This is due to an increase in carbon dioxide in the atmosphere through the ...

Produced by Nelson Thornes, this resource helps students look at aspects of how science works. In particular, students are asked to plan an investigation into whether water expands when it freezes or when it thaws. The context is set by considering that in winter many people report burst water pipes when a thaw...

Donald Palmer's job involves studying, and teaching others how, the human body protects itself from infections and malfunctions, including cancer. He is especially interested in the way the immune system changes with age, and examines the surfaces of human cells using chemicals and instruments.

Produced by Nelson Thornes, this resource helps students look at aspects of how science works. It looks at the different forms of smog that affect major cities because of their high density of population and air pollution from industry and motor vehicles. The activity is designed to let the students review the...

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...

This Science upd8 activity draws on clinical trials. Eight young volunteers had been in clinical trials before, but this time things went horribly wrong. Six of the eight were left fighting for their lives. In this discussion activity students consider whether new treatments should be ever tested on human...
