This video uses an anechoic chamber to investigate whether an echoless environment can significantly change our perceptions.

This video demonstrates how the eye tracks motion in such a way that determining whether an object is accelerating is very difficult. So, we need another way to measure motion.

This video demonstrates how a theory cannot be proved.  Theories at best allow observations to be explained at that time, but there may be other explanations still to be discovered. The scientific method is rigorous in attempting to disprove a theory. Only when we fail to disprove our theories do we say we have...

Produced by The Centre for Industry Education Collaboration (CIEC), these resources challenge students to develop strategies for the profitable operation of fertiliser manufacturing in the United Kingdom.

Students gain an understanding of how science is used in an industrial context. The use of energy and...

A Catalyst article explaining how carbon capture and storage can reduce the amount of carbon dioxide entering the atmosphere and may reduce the effects of climate change. Burning fossil fuels releases carbon dioxide into the atmosphere. This is a major contributor to climate change but can CO2 be captured and...

This podcast from the Planet Earth Online collection and the Natural Environment Research Council (NERC) looks at how carbon capture and storage works, why it's here to stay, the effect of floodplains on water pollution, and how the thickness of polar ice can be measured from space. The venue for this Planet Earth...

A Catalyst article about carbon dioxide which can be used as a solvent in industry, or as a regulator of blood pH. This article looks at some other uses of carbon dioxide and considers its importance in global warming. It also explains how the greenhouse effect is a natural part of the operation of the Earth's...
