This video introduces a reliable technique to demonstrate tissue culture and totipotency, and shows how best to use this protocol with your students.

Unlike animal cells, many plant cells are totipotent, meaning that...

This colourful leaflet from the Natural Environment Research Council (NERC) looks at how environmental factors have affected human evolution. It includes a timeline and map showing how and where humans have developed and changed over millions of years.

Humans are a truly global species. We have colonised...

Cholera is an infectious disease caused by the bacterium Vibrio cholerae. There have been seven worldwide disease outbreaks or pandemics since 1817, killing millions of people and infecting millions more. This resource, from the Microbiology Society, charts the history of the disease and investigates the causes,...

Produced by Science & Plants for Schools (SAPS), this activity enables students to investigate the effect of competitive and non-competitive inhibitors on the enzyme beta-galactosidase.

The chemical ONPG (o-nitrophenyl beta-D-galactopyranoside) is degraded by the enzyme beta-galactosidase. The product is...

This resource from Science & Plants for Schools (SAPS) is presented as a survival guide for students, describing how to handle numbers correctly, standard form, the use of scientific calculators, the definition of a mole, calculating molarity, Avogadro’s number, how to express concentrations and how to...

This resource, from the Microbiology Society, gives an overview of role of the immune system and how it is affected by training intensity. Exercise can have both a positive and negative effect on immune function and can influence an individual’s vulnerability to...

These eighteen assignments and a teachers' guide, from the Association for Science Education (ASE) aim to encourage non-scientists to embrace a little science. The aim is to increase student's skills whilst quashing a few "science is boring" stereotypes. All assignments have been written to cover a variety of non-...

Produced by the Wellcome Trust Sanger Institute, this resource contains an overview of the techniques involved in making a BAC (Bacterial Artificial Chromosome) library. It consists of an animation that covers the key stages in the process:

From the Wellcome Trust Sanger Institute, this animation shows a detailed overview of the processes involved in the dideoxy or Sanger method for sequencing DNA. This is the method used to sequence the human genome. The animation demonstrates the principles and techniques involved in the Sanger sequencing method,...

This resource provides background information for students about the structure of DNA, DNA replication, genetic engineering, cloning, genetic testing and DNA fingerprinting.

The activities for students include a practical activity where students extract their own DNA from cheek epithelial cells or plant...

This resource is designed to meet the specifications for the A-level practical endorsement in England (CPAC). However, it will make a valuable guide to dissection and scientific drawing of a flower for those following a variety of different specifications.

The ability to accurately observe, dissect and...

This is a modelling activity where students use sampling techniques to determine the distribution and abundance of organisms in a simulated habitat. Students will simulate the mark–release–recapture technique (Lincoln Index) for estimating population sizes of mobile species. 

Curriculum links include: ...

Produced by Science & Plants for Schools (SAPS), the investigations suggested in this resource use duckweeds. These seem to be simple plants - small, green, and with no flowers. However, this simplicity makes them ideal experimental organisms for investigations into...

From the Microbiology Society, this resource contains information about biofilms. These are communities of microbial cells attached to a surface. For example, the slime lining plugholes and drains or the rough deposit that can coat teeth at the end of the day. The information clearly describes: * What are biofilms...
