Produced by the Wellcome Trust, these animations take a detailed look at the molecular mechanisms that allow the dengue virus to subvert the cells of its mammalian host, allowing it to replicate and spread. Dengue is an example of an RNA virus.

Produced by The Centre for Industry Education Collaboration (CIEC), this resource looks at the testing of materials in the context of dentistry. Students first look at the properties of teeth and the nature of toothache before going on to test materials for a range of properties.

Experimental methods...

In this ARKive activity, students research and design their own conservation programme to learn about the importance of biodiversity as well as the economic benefits and services ecosystems provide. Using examples of successful conservation programmes within the UK Overseas Territories, students learn about the...

This resource, from the University of Nottingham, describes a number of investigations which could be carried out in heathland habitats. Heathlands are excellent habitats to use for designing and carrying out experiments. Plants are often relatively easy to identify when compared with other habitats and...

Design and make a seed from a newly discovered plant using junk materials.This activity provides an opportunity for creative thinking around the topic of germination and seed dispersal. It also supports the development of literacy and presentation skills. Further ideas...

This comprehension activity, aimed at students aged 11-14, looks at the role of the immune system in protecting us from infectious disease, and how it recognises the difference between the body (‘self’) and invader. This worksheet is part of a collection of materials based on...

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....

Di-deoxy sequencing is a way to determine the order of bases (A,C,G and T) in a piece of DNA.  A set of 4 lanes (one for each base) is needed to sequence any given piece of DNA. Wherever a black band appears in a particular lane...
