Through this Biotechnology and Biological Sciences Research Council (BBSRC) resource, students gain an understanding of the role of DNA within cells of the human body, and an appreciation that it is the uniqueness of their own DNA ‘recipe' which makes them individuals. The activities were first run as workshops...

Discovering New Medicines is the latest educational resource from Understanding Animal Research. This colourful and informative classroom poster takes the student through the medicines discovery process, from basic research to clinical trials and treatment approval.

The poster includes key facts such as...

These diagnostic questions and response activities (contained in the zip file) support students in being able to:

• Recall that the good health of all organisms can be compromised by diseases.

• Recall that diseases can be caused by germs, lifestyle, environment or information in the...

Produced by Nelson Thornes, this resource helps students look at aspects of how science works. In this activity students are given the results of an experiment to investigate the effectiveness of different concentrations of disinfectant and their effectiveness at killing bacteria. Students are asked to suggest a...

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: ...

This Catalyst article explores how many mammal species' bodies are adapted to cope with the great pressures involved as they dive to great depths.

This Economic and Social Research Council (ESRC) school briefing looks at the effectiveness of advertising and whether it really is necessary for advertisers to use very thin models to sell their products. Counter to this view, research shows that women are just as likely to buy a product if the model is of average...

Produced by the Science Museum, this resource sees students working in groups to explore the issues surrounding genetic testing. Students receive a sealed secret box, that contains a chance card. Opening the box represents taking a genetic test. Students have to decide whether they would want to open the box. In...

This Science upd8 activity draws on clinical trials. Eight young volunteers had been in clinical trials before, but this time things went horribly wrong. Six of the eight were left fighting for their lives. In this discussion activity students consider whether new treatments should be ever tested on human...

These three activities, from Centre of the Cell, demonstrate how double blind trials are run, explaining what a placebo is and how the placebo effect works, how bias is removed as far as possible and how participants and trial medicines are randomised. Through these activities, students investigate the placebo...

A series of images representing double helix images.

• DNA double helix and sequencing output: molecular model of a DNA double helix showing the individual atoms (apart from hydrogen) as coloured balls. Carbon atoms are in white, oxygen in red, phosporus in purple and nitrogen in blue....

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...
