A detailed, engaging and informative lesson presentation (50 slides) and accompanying worksheets that looks at the commonly misunderstood topic of chromatography. This lesson goes through paper, thin-layer and gas chromatography so that students can analyse and interpret the results that would be found on a chromatogram. The lesson begins by challenging the students to recall details of this separation method when they met it at KS3. Students will meet the two chemical phases, mobile and stationary, and begin to understand that this method relies on the distribution of substances between these two phases. Students will meet the calculation for retention factor and be shown how to tackle questions on this topic before trying themselves. Time is taken to go over the details of gas chromatography, in a step by step guide format, as this is a poorly understood topic. There are progress checks throughout the lesson, which include mark schemes and detailed explanations, so that students can assess their understanding and address any misconceptions that could arise.
This lesson has been written for GCSE students but could be used with A-level students
