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 short activity introduces students to the ideas of the footprint and resolution of an image, asking them to choose and use appropriate methods to calculate how these quantities would change as they moved a camera to a series of vantage points above the surface of the Earth

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...

Work done in this Nuffield 13 - 16 module followed from the unit called ‘Food and digestion’. This B unit provided enough material for six double periods in the third year of secondary school (year nine). The teachers’ guide included four worksheets to supplement the...

This activity uses a humorous video to raise a serious question: can science tell us what animals are saying, and interpret their emotions? The Bow-lingual dog translator claims to detect animal emotions by analysing bark sounds waves. Students use research evidence to decide whether the device does what it claims...

Using real data from CensusAtSchool 2000/2001, this resource explores issues around the disposal or recycling of the empty aluminium cans in schools. Students discuss the issue, calculate statistics, draw graphs and look further into what happens to empty cans in their own school. 

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.

A Catalyst article about the many roles of chemists at work. The links with biology, physics and geology are examined as are many other subjects. The article looks at some of the areas in which chemists work and it explores what makes it distinctive from other sciences.

This article is from Catalyst:...

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...

The Nuffield Foundation provide this resource which can be used to introduce the idea of representing objects using plans and elevations. Students will have the opportunity to identify everyday objects photographed from plan and elevation views, draw 3D sketches of solids from their plan and elevation views, as...

This in-service kit published by the Mathematics Centre at the University of Chichester was compiled from experiences of the writers, gained when working at, reflecting on and discussing mathematics. It is presented here in draft form to be used by teachers working...

This activity, from the Institution of Engineering and Technology (IET), provides an opportunity to assess students understanding of remote surgery.

It is intended that students will:
• Understand what remote...

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...
