This resource uses the context of the British Challenge for the America's Cup to explore composite and nano materials.  The video uses the challenge to build the highest performing racing yacht as an introduction to composite materials and how they are designed to improve their properties for a specific use.  This...

Produced by the Charles Darwin Trust, the activities in these materials help students to consider biodiversity within a habitat. To observe change over time, in 1846 Darwin planted a hedge at Down House. Twenty years later, he surveyed the hedge and recorded those species that had disappeared and new plant arrivals...

From the Charles Darwin Trust, these materials help students to consider the concept of how species are sustainable and how changes in the environment can lead to extinctions.

The activities look at how human activities have impacted on the Galapagos Islands since Darwin's visit. This includes effects on...

Produced by ARKive, this resource teaches key stage three children about biodiversity and classification whilst developing skills in independent research, collaboration and scientific thinking. It also gets students thinking about how scientists plan expeditions and surveys. A presentation introduces biodiversity...

This resource from Siemens looks at how the ear works and how sounds are converted into nervous impulses. The activities aim to develop student’s understanding of the concept of loudness and the decibel. A signal generator is used to compare loudness to frequency and to demonstrate how sound is represented in waves...

This ASE PowerPoint quiz game ia aimed to liven up topics revision and reinforce vocabulary. The presentation includes two sets of questions on solids, liquids, gases and physical properties. They challenge students to find the "odd one out" from four options provided. A paper version of the question options and...

The purpose of this Ofsted conference was the use of assessment in raising standards of teaching and learning. Workshops drew on good practice from Key Stage Two and Key Stage Three, and provided 31 delegates with the opportunity to work with other professionals on assessment for learning (AfL).
