The Open Air Laboratories (OPAL) network is an initiative which aims to create and inspire a new generation of nature-lovers by encouraging people to explore, study, enjoy and protect their local environment. OPAL began in 2007 with a total of 15 partners, headed by Imperial College London, working together to...

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 Catalyst article explains the code structure of DNA and looks into how it is copied across generations.

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...

This A-level tutorial video follows on from the the distance, speed and time video.  It looks at the terms displacement and velocity and how they differ from speed and time.  An example of a displacement / time and velocity / time graph is given and discussed.  A...

The ability to accurately observe, dissect and record an organism is a key skill for biology students. Many students are intimidated by the idea of making a scientific drawing, and struggle to develop their skills in this area.

This resource is designed to meet the specifications for the A-level...

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...

With this a-level video tutorial, the presenter talks about how we get the equation speed = distance / time and then looks at the differences between a distance / time and a speed / time graph.  It also demonstrates what the area under the graph represents as well as the gradient.  This can be followed by the...

Produced by the Learning and Skills Improvement Service, this activity takes students through a step-by-step approach to understanding the basic principles of distance-time and velocity-time graphs. Working through the activity will help students to:
* Understand the terms distance, time, velocity 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.
