These resources allow students to explore natural selection using different coloured baits (spaghetti ‘worms’) that are selected and eaten by birds. Uneaten ‘worms’ are counted after predation and the ‘worm’ population is replenished in proportion to those colours which remain. After several cycles of predation and...

A pair of videos that investigates the IV characteristics of a filament bulb. The first allows students observe the experiment, which is a required practical for students to be able to understand and carry out for GCSE Combined Science and Physics.  The second explains how to interpret the data, plot the graph and...

In this practical activity students analyse ice cores extracted from the icy worlds of Enceladus or Europa. This resource provides information about Enceladus and worksheets for both qualitative and quantitative analyses. In the video, Steve Althorpe explains how ice cores containing minerals can be made and then...

Produced by Science & Plants for Schools (SAPS), this resource suggests a range of ideas for extended investigations into plant growth and physiology. Each suggestion is given a brief description but details of experimental methods are not provided.

The resources in this collection show how you can take basic physics and chemistry demonstrations and change them into magic tricks. Each resources comes with teachers notes and a video which shows how to carry out the trick.

Produced by Science & Plants for Schools (SAPS), this activity enables students to look at the induction of the lac operon in the bacterium Escherichia coli (E. coli).

Lactose is found in milk but not in many...

This video clip demonstrates an investigation into the absorption of infrared radiation by different surfaces. This is a required practical for students to understand and be able to carry out for GCSE Combined Science and Physics.

A pair of videos that investigates the emission of infrared radiation by different surfaces.  The first allows students to see the experiment undertaken and the second clip explains how to plot a graph to evaluate the relationship. This is a required practical for students to understand and be able to carry out for...

Produced by Science & Plants for Schools (SAPS), this resource looks at the compounds produced by conifers that inhibit the growth of other plant species.

Conifers, such as pine trees, contain compounds which...

Produced by Science & Plants for Schools (SAPS), these materials look at the work of conservation biotechnologist, Jonathan Kendon. Through investigating the effects of human activity on the environment, students gain a greater understanding of the career...

Produced by Science & Plants for Schools (SAPS), these materials look at the work of the plant biologist, Julian Ma. Through seeing how natural and genetically-modified plants can produce medicines, students gain a greater understanding of the career opportunities...
