In this video clip radioactive decay is modelled using the rolling of dice. The data are plotted on a graph and the half-life is determined. 

Produced by Solar Spark, this activity shows how two metal plates and a person, can make a battery (cell). This helps to demonstrate how a solar photovoltaic cell works.

A solar cell has two electrodes. These have to be connected up to make a circle which we call an electrical circuit. One side is connected...

In this podcast from the Planet Earth Online collection and the Natural Environment Research Council (NERC), reporters find out what sexual conflict means for female guppies, how female promiscuity may be a good thing and why female mongooses all give birth at the same time.

In an extreme example of sexual...

'What will happen as we use up fossil fuels? Are we facing an energy crisis? Where will we get our energy from in the future?'

Understanding the nature of energy, how it moves from one place to another and how it can be changed from one form to another will help us harness energy more effectively in the...

Seven activity sheets produced by the Institute of Physics (IOP) to accompany the MODEL Project's Harnessing Energy video.

Worksheet one takes an overview of the topic. Worksheets two - seven are targeted at specific sections of the video.

Eight practicals produced by the Institute of Physics (IOP) that help students to understand energy transfer and transformation and the use of energy in its various forms.

Accompanied by the Teacher and technicians'...

If you travel from the UK to France via the channel tunnel, your carriage is riding on rails made of a particular kind of steel that Harry Bhadeshia invented. He has also developed the world's strongest armour, called 'super bainite', in part through the discovery of a steel that seemed to sing.

He has done...

A Catalyst article about the composition of sea water. The article looks at how the sea became salty, how the factors such as hydrothermal systems can affect it and it investigates whether its composition has always been the same.

This article is from Catalyst: GCSE Science Review 2005, Volume 15, Issue 3....

The short videos explore a variety of STEAM topics such as sound waves and frequencies, 3D...

This case study describes David Topping’s career path in environmental research, investigating how tiny atmospheric particles influence our climate and air quality. Some research can take place almost entirely in a laboratory, whilst other studies look at complicated interactions that are vast in scale or that take...
