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.

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...

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...

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 report, published by LSIS, describes a research project by Family Learning, Cheshire East Council. The research looked at resources and strategies for improving parental numeracy skills. This then tied in with tutor professional development.

This collection of resources supports the development of practice in behaviour for learning.

Produced by Science & Plants for Schools (SAPS), these activities look at career opportunities in plant biology, as well as useful classroom activities and practical investigations. The range of careers and activities covered include:

Produced in 2011 by the Learning Skills Improvement Service (LSIS), this case study tackles the theme of enrichment and enhancement in STEM. From Newcastle College, it describes an outreach project bringing local community organisations together with teaching staff.

By demystifying simple health tests (e.g....

Produced by the Learning Skills Improvement Service, these materials help to demonstrate effective practice. This case study, from Network Learning Centres UK Ltd, looks at the theme of embedding functional skills. In this instance, the planned implementation of functional skills was broken into four stages. This...

Produced by the Learning and Skills Improvement Service (LSIS), this case study looks at the theme of harnessing technology. The study describes ProVQ, a work-based learning provider, which wanted to improve the support to their motor vehicle apprentices while they were in the work place. ProVQ aimed to look at the...

The materials in this resource are from the Secondary National Strategy ‘Progressing to Level 6 and beyond in science’ project. They were intended for science teachers who are focusing on developing writing in science – specifically explanations, arguments and descriptions.

These materials consist of general...

Published by LSIS, this research report describes a project undertaken by New College Nottingham. The project describes the creation of a webquest to aid the learning of space exploration for a BTEC first diploma.

Using a blog facilitated a dialogue between the students themselves and also with the class...
