This detailed lesson will support students with their revision for the PAPER 4 mocks or final assessment. The wide range of tasks and activities will challenge their knowledge and understanding of topics 12 - 19 of the CIE A-level biology specification (for assessment in 2025 - 27), allowing them to identify those areas which require further attention before the examinations. Included in the range of tasks are exam-style questions and 34 short-answer understanding checks and all answers are embedded into the PowerPoint. As shown in the cover image, there are several quiz rounds to maintain engagement and to encourage healthy competition, as well as guided discussion periods to provide opportunities for students to support each other. The following content is directly covered by this revision lesson: Directional, disruptive and stabilising selection The evolution of antibiotic resistance Allopatric and sympatric speciation The Founder effect and genetic bottlenecks The Hardy-Weinberg principle Genetic terminology Calculating phenotypic ratios for sex-linked disease and alleles demonstrating codominance Autosomal linkage The events of meiosis which contribute to genetic variation Calculating the chi-squared value Mutations Gel electrophoresis The lac operon as an example of the control of protein production The three-domain system Classification taxa Saltatory conduction Structure of neurones The function of cholinergic synapses The role of abscisic acid and calcium ions in the response to water stress Skeletal muscle contraction Aerobic respiration The connection between the light-dependent and light-independent stages of photosynthesis Calculating the Simpson’s index of diversity Many of the tasks have been differentiated to maintain challenge whilst providing access to all. This is an extensive lesson with many tasks so it is estimated that it will take over 4 hours of teaching time if covered in full, but teachers may choose to use sections to focus on a specific topic.

This revision lesson provides students with the opportunity to assess their understanding of topic 7 and identify those areas which need revisiting. Included in the lesson is a multiple-choice assessment consisting of 20 questions and a PowerPoint revealing the answers, along with explanations and workings for the more difficult questions, and key points which relate to the AQA A-level biology specification.
