Candidates should be taught to:
 * use scientific knowledge and understanding to turn ideas into a form that can be investigated, and to plan an appropriate strategy;
 * decide whether to use evidence from first-hand experience or secondary sources;
 * carry out preliminary work and make predictions, where appropriate;
 * consider key factors that need to be taken into account when collecting evidence, and how evidence can be collected in contexts in which the variables cannot readily be controlled;
 * decide the extent and range of data to be collected, and the techniques, equipment and materials to use.
