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...

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 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....

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...

Produced by the Learning and Skills Improvement Service (LSIS), this case study looks at the themes of enrichment and enhancement in STEM, employer engagement and knowledge and technology transfer. By the National Marine Aquarium, the study demonstrates the potential for informal learning institutions to create...

Craven College in Skipton, North Yorkshire is twenty four miles from Leeds Bradford Airport where there are significant employment opportunities covering a range of areas in a busy airport e.g. pilots, ground staff and a range of auxiliary services. The College, through partnership with Jet2.com, Multiflight, TUI...

This report describes an action research project by Gateway College and is published by LSIS. The project supported BTEC Level 2 students as a pilot group to develop their literacy and language skills by integrating literacy into their science learning. This enhanced both student language competence and their...

A multiple choice quiz on fuels for A/AS level chemistry.

Although it is written for OCR AS/A level chemistry (Salters) H033/H433 course, it can be edited to suit your scheme of work.

James Briscoe studies the highly structured development of the central nervous systems in embryos. For James, personal drive and self-motivation are key to success in science. A better understanding of the development of the spinal cord will shed light on diseased and damaged nervous systems, and the hope is that...

A multiple choice quiz on metals for AS/A level chemistry.

Although it is written for OCR AS/A level chemistry (Salters) H033/H433 course, it can be edited to suit your scheme of work.

Produced by the Learning Skills Improvement Service (LSIS), this case study looks at the theme of knowledge and technology transfer. Written by Pera, it describes how research organisations, industry players and educational institutions worked together to create a suite of short technical courses.
