Unilever updated its series of Educational Booklets in the late 1960s. The company launched a Revised Ordinary Series and also began an Advanced Series. Detergents was the first booklet in the Ordinary Series. This booklet covers both soaps and soapless detergents. [b]Contents...

This is one of the 18 Background Books published for Stage II of the Nuffield Chemistry Sample Scheme. The books were highly illustrated designed to be attractive. This book describes applications of chemistry to cleaning.

There are three parts to this book:
*Part 1: Soap
This part explains how...

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.

In this resource students are given a quadrilateral with one angle of 60 degrees and varying side lengths- with two of the sides of equal length. The challenge is to calculate the lengths of the diagonals.

Each student worksheet contains a different quadrilateral, but the solutions all have something in...

As the number of cells in a microbial culture increases, turbidity increases. In this experiment students calculate doubling time and growth rate constant using absorbance as the measure of growth. Turbidity is caused by suspended cells in the growth medium scattering light, and may be measured using a colorimeter...

This experiment is a continuation of Determining Doubling Time. Students create a standard curve of absorbance against yeast concentration, and use this to determine the concentration of yeast produced over time.

The standard curve (dry mass, grams per litre) is generated from known concentrations of dried...

This resource requires students to consider the challenges of designing and developing a new sports venue. To make this challenge more manageable, it has been divided into four separate challenges: the site, the structure, the court and the environment. As well as researching and developing ideas, the challenge is...

In this resource, learners will investigate a decade counter circuit. They will then compare the operation of this to their programmable counter. 

This activity, suitable for a cross-STEM project day or series of lessons, focuses on how information can be provided to travellers on the London Underground. Students are asked to consider user needs – what information would they need to see, and how might their requirements be communicated? A deep understanding...
