Practical work is an essential feature of secondary science education. However, questions have been raised by some science educators about its effectiveness as a teaching and learning strategy. Whilst such an approach is generally effective in getting pupils to do things with objects and materials, it is seen as relatively ineffective in developing their conceptual understanding of the associated scientific ideas and concepts. Ian Abrahams argues that this is because it is practiced as a hands-on', rather than minds-on' activity.

UV and other forms of radiation cause severe damage to a wide range of materials from living organisms to manufactured products. Plastics materials and products exposed to UV light suffer weakening, discoloring and degradation. In this book, George Wypych provides a comprehensive reference guide to help those working with plastics to limit this damage and deterioration through the use of UV stabilizers.

The author begins with physics of radiation energy, transmission, and absorption and their effect on materials. The wide range of UV stabilizers available in the market is discussed...

Gaining a better sense of how pupils conceive school geography is crucial if we are to understand the ways in which their ideas and values mediate learning processes. Geography in Secondary Schools explores how pupils experience geography lessons, what they think geography as a school subject is about, and what it means to them. School geography aims to help young people think about the world and their place in it in a distinctive - geographical - way. However very little is known about the kinds of thinking and values they associate with the subject.

Researchers are increasingly...
