This detailed and engaging lesson supports students with their revision in the build up to their PAPER 1 (Biological processes) mocks or final assessment. The wide range of tasks and activities will challenge them on their knowledge of modules 1, 2, 3 and 5 of the OCR A-level biology A specification, allowing them to identify any areas which require further attention before the examinations. Included in the range of tasks are exam-style questions and understanding checks and all answers are embedded into the PowerPoint. There are 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: The nature of the genetic code Globular and fibrous proteins Protein structure The role of the heart valves in the cardiac cycle The conduction system of the heart The autonomic control of heart rate The mitotic cell cycle DNA replication The events of meiosis that contribute to genetic variation The structure of starch and cellulose The light-dependent and light-independent reactions of photosynthesis The ultrastructure of eukaryotic cells Calculating the size of an object under the optical microscope Saltatory conduction The structure and function of sensory and motor neurones Depolarisation and the initiation of an action potential 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 3 hours of teaching time if covered in full, but teachers may choose to use sections to focus on a specific topic. If you and your students enjoy this lesson and find it beneficial, a revision challenging the content of modules 1, 2, 4 & 6 as assessed in PAPER 2 (Biological diversity) has also been uploaded.
