By Solar Spark, this activity explores the relationship between light scattering and colour through anodising. This is the electrochemical process used to thicken the protective oxide layer found on several metals. Aluminium is the most common metal treated in this way, but others, including titanium can also be...

This Nuffield Working with Science unit aimed to give students the experience of designing experiments, carrying them out, and evaluating the results. The unit explores the paranormal which is a field where there are many strongly held beliefs, often unsupported by...

This Nuffield Working with Science unit aimed to draw on the popularity of bird watching to develop skills of observation and investigation.

Guidance for teachers and technicians appears in...

The core of this Nuffield Working with Science unit is made up of sections covering the preparation and testing of beer, the science of brewing, and the effects of alcohol consumption.

Produced for Future Morph, this video clip shows an apprentice in motor vehicle maintenance talking about her work and college course. She describes how a car's engine is tested to find a fault with its fuelling. An additional activity describes a classroom demonstration that shows the products of hydrocarbon...

From Solar Spark, this activity allows students to see how chlorophyll can be energised and how this causes it to fluoresce. Chlorophyll in plant leaves absorb red light and pass the energy on to other parts of the plant, hence leaves look green. But if there is nowhere for the energy to go, it gets released as...

Two translucent liquids are mixed. At first, nothing happens: the resulting solution is still translucent. Suddenly, with no warning, the solution turns blue-black all at once.

Curriculum links include redox reactions, rate of reaction, kinetics

The enzyme lactase is widely used in the dairy industry to convert the naturally occurring disaccharide sugar lactose into glucose and galactose. In this practical students investigate the treatment of milk with lactase. Following treatment they test the glucose content of the converted milk, and compare products...

This Nuffield Working with Science unit was intended to help students to appreciate the purposes of different types of cosmetics, to distinguish between purely decorative and 'useful' preparations, to understand the reasons for the formulations of different types of...

This Nuffield Working with Science unit featured experiments derived from forensic techniques but could only give the 'flavour' of a scientific investigation of a crime. The unit aimed to emphasise the basic needs, in a scientific investigation of evidence, of accurate...

This Unilever Laboratory Experiment, published in 1973, describes two methods for determining the vitamin C in foods. The leaflet describes the estimation of vitamin C (L-ascorbic acid) in foodstuffs, after extraction with metaphosphoric acid, by titration with a standardized dye, 2,6 dichlorophenolindophenol,...
