Paper 2 REVISION (AQA A-level biology)

This extensive revision lesson challenges students on their knowledge and understanding of the content of topics 5 - 8 of the AQA A-level specification. The PowerPoint and accompanying resources are detailed and engaging and contain a selection of tasks which challenge the following points:

• Directional, stabilising and disruptive selection
• Saltatory conduction and other factors affecting conductance speed
• The structure of a motor neurone
• Sensory receptors, depolarisation and initiation of an action potential
• Hardy-Weinberg principle
• Genetic terminology
• Codominance and sex-linkage
• Autosomal linkage
• Chi-squared test
• Phosphorylation
• The stages of aerobic respiration
• Explaining lower ATP yields in anaerobic respiration
• Skeletal muscle contraction
• Structure and function of slow and fast twitch muscle fibres
• The control of heart rate
• Electrophoresis and genetic fingerprinting
• The secondary messenger model

The students are tested through a variety of tasks including exam questions, understanding checks, and quiz rounds to maintain engagement. Due to the mathematical content in all A-level exams, there is also a focus on these skills. The answers to all questions are embedded into the PowerPoint so students can use this resource outside of the classroom.

The delivery of the whole lesson will likely need at least 2 or 3 hours of contact time so this resource could be used with students in the final weeks building up to their paper 2 exam, or alternatively with students before their mocks on these topics.
