This Association for Science Education (ASE) publication about safety in gas appliances was developed in association with the British Gas Corporation. At the time, this was the only gas industry in the world to be involved in every aspect of gas supply.

This Association for Science Education (ASE) publication about extracting metals from scrap was developed in association with ECR Ltd. This was a secondary copper refining company which was first established in Birmingham in 1807. Its origins could be traced back to...

This Association for Science Education (ASE) publication about properties of metals was developed in association with the British Aerospace Dynamics Group. At the time the Dynamics Group employed over 20,000 people at ten major design/production establishments...

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...

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

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,...

This Unilever Laboratory Experiment, published in 1970, describes the procedure for a titration with EDTA and Eriochrome Black T to determine the total hardness of water. The details cover the preparation of a standard solution of EDTA as well as the steps of the titration.

This mystery deals with a laboratory report in which the written results suddenly vanished. The students need to find out how the writing vanished,  how to recover the vanished data, and what the secret of the pen is.

Gelli Baff, a crystalline powder, has been dumped into a bathtub filled with water. How can you force the hydrogel to go down the plughole in order to drain the bathtub? 

In this investigation, students learn about swelling reactions, balanced reactions, and polymerisation. Students should be able to...

These resources were developed by the Gatsby Science Enhancement Programme and the Centre for Science Education at Sheffield Hallam University in order to demonstrate new ways that ICT can be used to enhance practical work in science. Research scientists use computer technology in both the collection and the...

This Unilever Laboratory Experiment, published in 1966, describes the use of steam distillation to separate oil from crushed cloves. The method for extracting the eugenol from the oil used carbon tetrachloride (tetrachloromethane) and so would need to be modified before this could now be done in schools and...
