The Nuffield Chemistry course for students aged 11-16 was first published in 1966. By 1971 the materials had been well tried in many schools. Dr Richard Ingle was appointed to prepare a second edition of the resources in the light of all the feedback from teachers....

These Fun-Size activities, from the Association for Science Education (ASE), are short 5-15 minute tasks that enliven lessons. This resource is part of the SYCD Can we; Should we? collection. The activities range from short games and word plays through to quick demonstrations. Fun-size is particularly useful when...

The Nuffield Advanced Chemistry students’ books were not intended to be conventional textbooks, or background books, or books of data. The books were deliberately left in many ways incomplete. The aim was to provide students with a series of starting points from which...

This package of Core Maths resources introduce students to exponential growth and decay by exploring exponential functions, compound interest for savings and depreciation of assets.

Exponential Growth and Decay: Teacher Guidance

This teacher guidance contains information including...

A Catalyst article providing examples of some drugs derived from natural substances. Many drugs which are commonly used today are similar to naturally occurring compounds which have been used for centuries to treat illnesses. Chemists have identified and purified these substances. By determining their molecular...

A Catalyst article investigating what nitrogen and its compounds are used for. Nitrogen is colourless, odourless, non-toxic and inert, and has a wide range of uses. Nitrogen makes up seventy eight per cent of the Earth’s atmosphere by volume and has a considerable influence on respiration in plants and animals. The...

Produced by Science & Plants for Schools (SAPS), this investigation looks at the taste of different fruits and vegetables. Domesticated fruits and vegetables have all been selectively bred so that they contain a particularly attractive taste for humans.

This study guide, from the Department for Education, is part of a suite designed to support the development of aspects of subject knowledge. It has been designed to link with the Progression Maps, the Revised Framework for teaching Secondary Science and Assessing Pupils...

This is a CPD taster created to give teachers a better understanding of what to expect when joining one of our secondary science courses. Below you will find a video and a task for you to do in your own time. Once you have done the activity, ...

These diagnostic questions and response activities (contained in the zip file) support students in being able to:

• Use observations to determine whether a substance is in solution.

• Recognise that a compound has properties (including solubility) that are distinct from its...
