\lfpar MATERIALS TITLE PAGE
This section allows the user access to several lists, displaying the many materials covered on this disc in eight different sets according to their properties. Access is via one of the eight categories displayed on the pictures.
As well as access to the lists, an introduction to each different set of lists, available by pressing on the 'introduction' button, explains the different sets and how and why different materials display the different properties mentioned.
@
\lfpar MATERIALS - INTRODUCTIONS
This section presents an introduction to some different physical properties which are used to group materials. Seven different sets of physical properties are discussed. The groupings of materials within each physical property set are described.
@
\lfpar MATERIALS - SELECTION LISTS
This section provides alphabetically sorted lists of the materials according to certain physical properties that they display. From these lists, access can be made to further information on each material by locating the required material in one of the lists and selecting the investigate button.
@
\lfpar MATERIALS - INVESTIGATE SCREENS
This section provides information relating to each material. All the materials have a 'general' section, giving a brief introduction to that material and a 'composition' section. Then, where appropriate for each material, the 'occurrence', 'extraction', 'production', 'applications' and 'history' are described. Any other relevant information, not fitting into any of these categories is displayed in the 'other' section. Not all categories are relevant for each material: For example, most manufactured materials will not have an 'occurrence' section.
Each section is available by clicking on the required button. For any section, selecting the 'others' button at the top of the page will give a list of materials, with all the materials available for that section highlighted. Any of the highlighted materials can then be selected.
At any point the tests section for any material can be accessed by clicking on the tests icon at the bottom of the screen.
@
\lfpar TESTS - TITLE PAGE
This screen provides access to fifteen different standard physical and chemical tests that can be carried out on the materials in order to identify them. Access can be made by selecting the required material at the top of the screen using the 'others' button. Clicking on the required test will then provide the information for the material chosen and an investigation into the required test can be made. For the melting point, boiling point, thermal conductivity, resistance, elasticity and tensile strength tests an interactive animation is available showing the experiment in progress and allowing you to take readings and make calculations from the results.
As well as access to the tests themselves, a tutorial section, obtained by pressing on the 'tutorial' button, is available for each test. The tutorial gives a description of each test and why and how it is carried out. For the resistance tutorial an interactive section is available showing the wiring up of the electrical circuit required in the experiment.
@
\lfpar TESTS - TUTORIALS
The tutorial section provides a description of the tests carried out on each material. The tutorial describes the test, detailing the relevance of the test and why it is used to identify materials.

This section describes the appearance of each material, giving a description of the material, followed by a description of what the material looks like on closer examination.
@
\lfpar TESTS - SOLUBILITY
This section demonstrates the solubility of a material in water and dilute hydrochloric acid. Some materials are soluble in one or both solvents, other materials are soluble in neither solvent. The final section 'A suitable solvent' names the solvent most used to dissolve the chosen material.
@
\lfpar TESTS - ACTION OF HEAT
This section demonstrates what happens to a material when it is heated in air. The method used is provided along with a description of what happens during and after heating the material. Any conclusions, giving information on what the test shows the material to be, is provided in the 'conclusions' section.
@
\lfpar TESTS - HEATING WITH CUO
This section details an experiment showing what heating a material mixed with copper oxide (CuO) can test for. The method and results are given, as is information indicating what substances can be tested for, thus giving information showing the nature of the material being tested.
