A Catalyst article about whaling. During the last century whales were hunted and killed by many nations for the valuable materials they provided. Whale populations collapsed as a result. The article looks in detail at this example of human impact on the environment and details whale populations throughout the world...

This Catalyst article explains the use of stem cells to treat medical problems, and outlines new possibilities for the use of adult stem cells in treatment.

Currently, stem cells used for treatment are embryonic stem cells, since they have the ability to form any cell type in the body. The example of the use...

This article from Catalyst looks at aurora borealis caused by the interaction of the solar wind with the Earth's magnetic field. It also explains how satellites are testing thoeires of how this happens. Auroral light emission occurs at roughly 100 km altitude. Energetic electrons in the solar wind cause the...

From the Science and Technology Facilities Council (STFC), this resource describes the new and exciting subject that brings together many different branches of science. Astrobiology is the study of how life formed and developed on the Earth, the conditions that made this possible and whether these conditions can...

This Catalyst article looks at Biochemistry, the study of chemical reactions in living things, exploring how it differs from other biological subjects and how examples can be found in everyday life.

This article is from Catalyst: Secondary Science Review 2011, Volume 22, Issue 2.

Geothermal energy is the heat produced by decay of radioactive isotopes deep within the Earth. The temperature at the centre of the Earth is thought to be around 5,000°C, with the temperature reducing toward the surface. It is estimated that 99.9% of the planet is above 100°C. Geothermal energy is considered a...

This Economic and Social Research Council (ESRC) school briefing discusses fat as a class issue, as well as a feminist issue. Research shows that middle class families are more likely to be health-conscious eaters, and chances are the shops in their neighbourhoods offer a wider range of healthy food. The resource...

With so many research groups across the world, it can be difficult for scientists to keep on top of the latest developments and findings. As well as publishing in journals (such as Nature or Science), researchers communicate their results at scientific conferences. These range in size from small, specialist...

This is one of the 14 Background Books published for Stage III of the Nuffield Chemistry Sample Scheme. The books were highly illustrated and designed to be attractive. This book is mainly an account of theories of acidity with examples to explain the importance of acids.

There are two parts to this book:...

This resource explains how important it is that social research is conducted in a scientific way, following definite rules that have been developed over time with the aim of ensuring that the results are not just the product of the researcher’s own beliefs. The paper stresses the importance of research being valid...

In this task students are required to estimate dimensions and use given densities to calculate an estimate for the mass of a number of objects. Calculators and/or spreadsheets are recommended when substituting into the formulae for the volume and mass of the solids.

The teachers' notes give a suggested...

This resource, from the Royal Observatory Greenwich, looks at what information we can gather by viewing (but not visiting) different parts of the universe.
