The aim of this unit is to enable learners to use a range of practical techniques used in science such as the analysis of substances, the separation of substances and the use of instruments/sensors. The variety of techniques in the content allows the unit to be tailored to reflect the focus of different areas of study, eg forensic science, biology, chemistry, physics, electronics and environmental science.

 

In all of these areas the ability to work safely and accurately and to appreciate the properties of materials is important. When scientists undertake investigations, they may need to know what substances are present. For example, an investigator of a pollution incident may need this information to identify the cause of the pollution. A scientist checking the purity of a pharmaceutical product may also need to know the nature and the quantities of impurities present. Learners will gain experience of both these types of analytical method:

qualitative and quantitative.

 

The ability to sample and test substances and materials is important in many branches of industry, in research work and in forensic science. In order to do this, learners need to be able to select and use appropriate instruments for the work being carried out. In this unit they will gain experience of a range of instruments and their use.
