This booklet is part of the ‘Innovations in Practical Work’ series published by the Gatsby Science Enhancement Programme (SEP). Novel materials have surprising properties which make them useful in many applications. The interesting and unusual behaviours of these new materials can generate excitement amongst...

This Nuffield Physics Guide to Experiments was designed to supplement Teachers' Guide III by giving details of the class experiments and demonstrations to be done during the third year of the Nuffield O-level physics programme.

A special feature of the guides was the very clear, three-dimensional diagrams of...

In this Salters’ Science biology extension module, sporting contexts are used as a basis for study of various systems within the body. The module also considers how diet, exercise and life-style can contribute towards fitness and good health.

The purposes of this Revised Nuffield Chemistry option were to review the historical development of a field of chemistry with special reference to its applied and social aspects; to study the life and work of one or more famous scientists working in the field; to create an interest in the original writings of...

The first option of Revised Nuffield Chemistry explored the remarkable properties of water and sought to explain them in terms of the polarity of water molecules and hydrogen bonding. Experiments also investigated the properties of detergents and hardness of water. A further topic was the monitoring of water...

Teachers and students had considerable freedom in their response to this Revised Nuffield Chemistry option because under O-level regulations it was teacher assessed. Practical work was based on a ‘real’ industrial process from the fine chemicals industry.

This topic explores flat designs which can be folded and used to package food and drink. These Cre8ate maths activities provide rich experience of visualising 3 dimensional shapes from 2 dimensional representations. In Four Chocolates and It Takes the Biscuit!, students will need to measure accurately and construct...

Three practicals produced by the Institute of Physics (IOP) that help students to understand some of the physics used in medical analysis. In addition to the guidance included for specific activities, please refer to the generic health and safety information before commencing any practical activity. This resource...

The Pit stop activities from Cre8ate maths are designed to motivate students to investigate the performance of model solar cars through a series of racing challenges. To do this activity you will need a set of model solar racing cars which are often shared between design technology and science departments. Students...

This Salters’ Chemistry Course unit from the University of York Science Education Group covered:
* The preparation of plastics by polymerization.
* The importance of ethene as a source of plastics.
* The uses and properties of plastics.
* The use of...
