PAPER 4 REVISION (CIE A-level biology)

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.
