A podcast from the Planet Earth Online collection and the Natural Environment Research Council (NERC). The Food Standards Agency advises everyone to eat at least two portions of fish a week, one of which should be oily, because it is good for us.

Unfortunately our appetite for fish and other seafood has...

From the National Non-Food Crops Centre, this factsheet looks at the production of vegetable oils and biodiesel for vehicle fuels. The factsheet gives information on the benefits of using bio-derived oils and also the economics of production. It also provides information on the use of biofuels.

This edition of Vegetable Oils and Detergents was a revised edition, published in 1973, of the original educational booklet. The book concentrated on the production and commercial extraction of fats and oils, the basic raw materials for two of Unilever's most important industries - margarine manufacture and soap-...

From the Science and Technology Facilities Council (STFC), this wall chart describes the space mission to Venus, the UK experiments aboard, and the extreme conditions on the surface of Venus. In addition to mission details, the resource describes properties of Venus and the conditions found on the surface of the...

A Catalyst article about the European Space Agency (ESA) which has sent the Venus Express spacecraft to explore Earth's cloudy neighbour. The purpose of the project, which is primarily to gather information about the atmosphere around Venus, is explained and is put into context with concerns about climate change on...

Purpose: Providing students with verbal feedback on their work avoids problems some students encounter when interpreting written comments. Using digital technology to record and then provide access to verbal feedback saves the teacher valuable lesson time and can be replayed by the student at will.

A selection of films suitable for use in the classroom presented by Derek Muller the from the ever popular Veritasium YouTube channel . 

Physicists are involved in a wide range of activities, including electronics, energy, space, transport, medicine and materials. Their work can involve designing and conducting experiments, simulating real-life problems and conditions in laboratories, or making a series of observations which are written up in...

Purpose: Recording a video clip of motion or colour change is an effective means of generating data, but video can also be created to communicate the methods and findings of a practical science activity.

Teaching approach: Still images, and video clips can be imported into a video editing app, where they can...

Purpose: As an alternative to traditional methods of investigating motion in the classroom, such as ticker tape timers or light gates, it is simpler and cheaper to analyse video clips of the movement of objects. Cameras in mobile phones and tablets can record a brief video which when imported into a video analysis...

These animations from the Wellcome Trust, illustrate that, unable to replicate without using the cellular machinery of more complex organisms, viruses invade and hijack their host's cells, resulting in serious disease.

The animations use the examples of Dengue virus to show how an RNA virus replicates using...

Purpose: Field trips can be difficult to organise in schools and so may be limited in scope and duration. Using virtual reality technology, it is possible to supplement a field trip with observations from other sites, to broaden the context studied.

Teaching approach: Once students have analysed data from...
