OCR A-level Biology A PAPER 2 REVISION (Biological diversity)

A considerable amount of time and thought has been put into the design of this extensive resource with the aim of motivating students to evaluate their understanding of the content in modules 1, 2, 4 and 6 of the OCR A-level Biology A specification which can be assessed in PAPER 2 (Biological diversity). The resource includes a detailed and engaging Powerpoint (226 slides) and is fully-resourced with differentiated worksheets that challenge the students on a wide range of topics.

The resource has been written to include different types of activities such as exam questions with explained answers, understanding checks and quiz competitions. The aim was to cover as much of the specification content as possible but the following topics have been given particular attention:

• Genetic terminology
• Monogenic and dihybrid inheritance
• Hardy-Weinberg principle
• Sex-linked diseases
• Blood clotting
• The properties of water
• Codominance and multiple alleles
• Types of variation
• Communicable diseases
• Genetically engineering bacteria to produce insulin
• Antibiotics and antibiotic resistance
• Vaccinations
• Ecological terminology
• Classification hierachy
• The genetic code and gene mutations
• Chi-squared test
• Epistasis
• Sampling
• Selection pressures and types of selection
• The Carbon cycle

Due to the size of the resource and the range of topics that are covered, this is likely to be used over the course of a number of lessons and will enable teachers to pinpoint specific areas to spend more time on. The mathematical element of the course is challenged throughout the lesson and helpful hints are provided to support students in structuring their answers.

This resource can be used in the lead up to the actual Paper 2 exam or earlier in the course when a particular area of modules 1, 2, 4 or 6 is being studied. I truly hope that this resource helps your students in their aims to achieve their potential grades.
