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...

This resource created by the IET is one of a series of resources designed to allow learners to use the theme of the men’s football World Cup to develop their knowledge and skills in design and technology. In this activity, learners will design a sports team logo.

The activity could be used as a one-off main...

Produced by the Learning Skills Improvement Service, these materials help to demonstrate effective practice. This case study, written by Options 2, looks at the themes of embedding of functional skills and the wider sector.

Options 2 provides training for young people to enable them to achieve the skills...

This booklet contains a number of case studies of lessons that emphasise working with what students already know and working from concrete ideas to the abstract. Each case study explains the task, contains examples of students’ work and explains how the lesson was followed up. [b]The function game[/b] is one way in...

This National Strategies study guide offers tried and tested practical suggestions for teachers to use in the classroom when considering the teaching of How Science Works. A variety of tasks help teachers to focus on developing their own creativity and critical thinking, transferable skills which they can pass on...

Published in 2009 by LSIS, this report describes research at Stockton Riverside College, Bede Sixth Form. The report had several aims: * to explore attitudes to e-learning for learners studying AS biology * to evaluate learner perceptions of the usefulness of e-learning resources * to develop new e-learning...

Produced by the Learning Skills Improvement Service, these materials help to demonstrate effective practice. From Grantham College, this case study looks at the themes of knowledge and technology transfer (KTT) and STEM skills for the future. This case study describes an activity to update staff knowledge and...

This article, from the Association of Teachers of Mathematics (ATM) publication ‘Mathematics Teaching’, and is taken from MT180.

Judith Steven and Kym Scott argue the importance that primary school teachers plan activities for children’s mathematical development out-of-doors. The activities should be...
