This very basic video shows what people believe water is.  It might be useful as a discussion point.

With the increasing pressure of a growing human population it is becoming increasingly difficult to conserve natural habitats. Ultimately, not every green space can be afforded conservation protection. This field study encourages students to act as environmental scientists to compare different habitats and decide...

Conditions on other planets are unlikely to be within the same ranges as that experienced by Earth. However, a degree of variance from ‘ideal’ ranges may be tolerable for a small number of organisms known as extremophiles. This investigation looks at the effects of subjecting a living organism (yeast) to some...

Produced by the Royal Observatory Greenwich, this booklet introduces the concepts of dark matter and dark energy. Included is an online video that discusses how the Universe will end, including the role of dark matter and energy. The booklet describes the composition of the Universe, this is followed by questions...

Sports engineers from Sheffield Hallam University and Frazer Nash are helping Team GB's wheelchair paralympians fine-tune their equipment and training regimes using advanced analysis technology. Engineers explain the relationship between science and engineering in disability sports and how inspiring it is to work...

This Catalyst article looks at agricultural plants, that are prone to many diseases, and scientists who develop new techniques to fight these diseases.

This physics extension module from the Salters' Science course focuses on the physics and electronics behind each part of a television set. Production of electron beams and their deflection by electrical or magnetic fields are shown and students see how colours can be...

This Catalyst article explains why there are many anti-bacterial drugs but few antivirals. There are millions of bacteria everywhere – on skin, in the gut, and on food. Bacteria have been troubling human beings for as long as they have been around, so a lot of effort has been directed into finding ways to fight...

This podcast from the Natural Environment Research Council's (NERC) Planet Earth Online collection looks at how scientists are using fish scales to figure out why the UK salmon population is falling; and how carbon dioxide emissions from power stations could be used to make household bricks.

Salmon numbers...

From Understanding Animal Research, these materials help students understand the process of drug discovery and development. It shows that the drug discovery process is long and complex and involves several different stages, including basic research, animal testing and clinical trials. The materials include: *...

A Catalyst article looking at how living organisms can act as biological indicators of problems in the way the environment is managed. Skylarks and other birds are disappearing from farmland. The article looks at how the statistics have been obtained, how and why bird numbers have declined and what can be done to...
