This downloadable video is part of the multimedia package Stuff and Substance, developed by the Gatsby Science Enhancement Programme (SEP). It can be used to show water condensing out of the air. A pure sample of water is normally in the liquid state at room temperature, but water particles can remain separated...

These technical briefs look at the ways Practical Action have helped poor communities to make the best use of their own labour and to use locally produced building materials and techniques that they can afford and manage.

Technical briefs are documents produced by Practical Action which are freely available...

A Year Ten module from the Salters’ double award science course. A surveyor’s report on a proposed barn conversion is used to introduce different materials used in construction and issues associated with their use. The lessons which follow then consider each type of...

These resources were developed by the Gatsby Science Enhancement Programme in collaboration with Keele University in order to provide support for teaching aspects of ‘How Science Works’. The emphasis of the materials is on ‘data, evidence, theories and explanations’ linked to ‘applications and implications of...

This is one of a series of focused units, from the Association for Science Education and the Design and Technology Association, to introduce students to important technologies and their applications. This unit features control systems and their applications to...

These activities, produced by The Centre for Industry Education Collaboration (CIEC), are based on a BASF chemical plant at Seal Sands, Middlesbrough. They enable students to see how and why chemical reactions are controlled in a chemical plant. The materials contain full teacher guidance, student notes and...

Comets are considered to be time capsules containing information about the conditions of the early Solar System. In order to understand what comets are, where they come from, and their influence on the evolution of Earth, it is necessary to find out what material they contain. This teacher demonstration and student...

A Catalyst article about the work of a scientist from the British Antarctic Survey, gathering data about climate change by studying ice cores from Antarctica. One of the areas of research was to find out whether it is possible to learn how much sea ice there was around Antarctica in the past by measuring how much...

This Catalyst article looks at how scientists can use material recovered from archaeological sites to see how crops have been introduced to different countries over the history of farming. Three processes by which some plant material can be preserved are explained. The ratio of carbon isotopes from the collagen in...

This is one of the 14 Background Books published for Stage III of the Nuffield Chemistry Sample Scheme. The books were highly illustrated and designed to be attractive. This book describes applications of chemistry to solve practical problems.

There are three parts to this book:
*Part 1: What is...

From the Technology Enhancement Programme (TEP), this publication looks at the process and problems caused by the corrosion of metals. The first part of the publication gives background information for students on elements, atoms, ions and electrochemical reactions involved in rusting. This helps students to...

This resource provides a cross-curricular design and technology and science project aimed at primary children. Using the context of the school class going to Greenland and forgetting all their shoes, children are asked to construct shoe soles that will insulate them as they take part in a dog-sled trip. Children...
