This REVISION resource has been designed to motivate and engage students whilst they are challenged on their knowledge of the content in topics C6-C10 of the AQA Trilogy GCSE Combined Science specification which can be assessed on PAPER 4. This is fully-resourced and contains a detailed PowerPoint (118 slides) and accompanying worksheets, some of which have been differentiated. The resource was written with the aim of covering as many C6-C10 sub-topics as possible, but the following ones have received particular focus: Pure substances in Science Chromatography Detecting gases Reversible reactions Changing conditions and the position of the equilibrium Factors affecting the rate of a chemical reaction The structure of the alkanes Complete combustion of the alkanes Cracking and the alkenes Fractional distillation of crude oil This resource can be used in combination with the PAPER 3 revision resource which covers the content in Chemistry topics C1 - C5 as well as the other AQA GCSE Combined Science REVISION lessons which I’ve uploaded
