Course overview
Chemical analysis; The unit begins with a recap of the particle model, atomic structure and the difference between elements, compounds and mixtures which learners were introduced to in KS3. Learners will build on this by looking at the difference between pure and impure substances. The unit then moves into looking at how different separation techniques can be used to see what a mixture contains. Learners will carry out practical work to see these techniques in action as well as analysing results such as chromatograms to draw conclusions about what a mixture contains. Learners will also learn about gas tests to help identify products of chemical reactions. Those studying triple science will also look at experimental and instrumental techniques for identifying metal ions in compounds comparing the effectiveness of each approach.
Organic chemistry; In this unit learners will build on their knowledge of fossil fuels from KS3 exploring how crude oil is formed, extracted, separated and used as well as considering both economic, political and environmental problems associated with both extraction and use. They will focus on the 2 key processes of fractional distillation and cracking to obtain particular fuels as well as exploring the process of combustion to release the energy stored within these substances. Learners will look at how structure relates to properties of different compounds and how this impacts on use.
