This revision resource has been designed with the simple aim of motivating the students whilst they assess their understanding of the content found in module 4.2.2 (Classification and evolution) of the OCR A-level Biology A specification. This module is often brushed over by students which leads to misconceptions and therefore time has been taken to explain the important concepts so that key points are recalled and retained. The resource includes a detailed and engaging Powerpoint (85 slides) and associated worksheets, some of which are differentiated to allow students of differing abilities to access the work. The range of activities have been designed to cover as much of the content as possible but the following sub-topics have been given particular attention: The biological classification of a species Classification hierarchy The three-domain and five-kingdom classification The features of the five kingdoms Phylogenetic trees Anatomical, physiological and behavioural adaptations Calculating the standard deviation Continuous and discontinuous variation In addition to these topics, some topics from other modules such as cell division and prokaryotic cells are tested in order to challenge the students on their ability to make links between the modules. The range of activities include exam questions and understanding checks as well as quiz competitions to maintain student engagement.

This fully-resourced REVISION lesson has been written to challenge the students on their knowledge of the content of topic 8 (Transport in mammals) of the CIE International A-level Biology specification. The engaging PowerPoint and accompanying resources will motivate the students whilst they assess their understanding of the content and identify any areas which may require further attention. The wide range of activities have been written to cover as much of the topic as possible but the following specification points have been given particular focus: The significance of the oxygen dissociation curves at different concentrations of carbon dioxide (The Bohr effect) The role of haemoglobin in carrying oxygen The role of haemoglobin in carrying carbon dioxide Draw the structures of red blood cells, neutrophils, monocytes and lymphocytes The relationship between the structure and function of a capillary The internal structure of the heart and its associated blood vessels Explain how heart action is initiated and controlled The pressure changes of the cardiac cycle The relationship between the structure and function of arteries and veins The double, closed circulatory system of a mammal Quiz rounds such as “Does this FLOW correctly” and “YOU DO THE MATH” are used to test the students on the finer details of their knowledge of the blood vessels and numerical facts

This revision lesson has been designed to challenge the students on their use of a range of mathematical skills that could be assessed on the six OCR Gateway A GCSE Combined Science papers. The mathematical element of the GCSE Combined Science course has increased significantly since the specification change and therefore success in those questions which involve the use of maths can prove to be the difference between one grade and another or possibly even more. The engaging PowerPoint and accompanying resources contain a wide range of activities that include exam-style questions with displayed mark schemes and explanations so that students can assess their progress. Other activities include differentiated tasks, class discussion points and quick quiz competitions such as “It doesn’t HURT to CONVERT”, “YOU DO THE MATH” and “FILL THE VOID”. The following mathematical skills (in a scientific context) are covered in this lesson: The use of Avogadro’s constant Rearranging the formula of an equation Calculating the amount in moles using mass and relative formula mass Calculating the relative formula mass for formulae with brackets Using the Periodic Table to calculate the number of sub-atomic particles in atoms Changes to electrons in ions Balancing chemical symbol equations Empirical formula Converting between units Calculating concentration in grams per dm cubed and volumes of solutions Calculating size using the magnification equation Using the mean to estimate the population of a sessile species Calculating percentages to prove the importance of biodiversity Calculating percentage change The BMI equation Calculating the acceleration from a velocity-time graph Recalling and applying the Physics equations Understanding prefixes that determine size Leaving answers to significant figures and using standard form Helpful hints and step-by-step guides are used throughout the lesson to support the students and some of the worksheets are differentiated two ways to provide extra assistance. Due to the detail of this lesson, it is estimated that it will take in excess of 3 hours of GCSE teaching time to cover the tasks and for this reason it can be used over a number of lessons as well as during different times of the year for revision

This is a fully-resourced lesson which uses exam-style questions, quiz competitions, quick tasks and discussion points to challenge students on their understanding of topics B1 - B5, that will assessed on PAPER 1. It has been specifically designed for students on the Pearson Edexcel GCSE Combined Science course who will be taking the FOUNDATION TIER examinations but is also suitable for students taking the higher tier who need to ensure that the fundamentals are known and understood. The lesson has been written to take place at the local hospital where the students have to visit numerous wards and clinics and the on-site pharmacy so that the following sub-topics can be covered: Cancer as the result of uncontrolled cell division The production of gametes by meiosis Mitosis and the cell cycle Sex determination The difference between communicable and non-communicable diseases The pathogens that spread communicable diseases Identification of communicable diseases Treating bacterial infections with antibiotics Evolution of antibiotic resistance in bacteria Vaccinations Genetic terminology Genetic diagrams Structures involved in a nervous reaction A Reflex arc Risk factors Chemical and physical defences Osmosis and percentage gain and loss Fossils as evidence for human evolution In order to maintain challenge whilst ensuring that all abilities can access the questions, the majority of the tasks have been differentiated and students can ask for assistance sheets when they are unable to begin a question. Step-by-step guides have also been written into the lesson to walk students through some of the more difficult concepts such as genetic diagrams and evolution by natural selection. Due to the extensiveness of this revision lesson, it is estimated that it will take in excess of 3 teaching hours to complete the tasks and therefore this can be used at different points throughout the duration of the course as well as acting as a final revision before the PAPER 1 exam.

This is a fully-resourced lesson which uses exam-style questions, quiz rounds, quick tasks and discussion points to challenge students on their understanding of the content of topics B4 - B6, that will assessed on PAPER 2. It has been specifically designed for students on the OCR Gateway A GCSE Combined Science course who will be taking the FOUNDATION TIER examinations but is also suitable for students taking the higher tier who need to ensure that the fundamentals are known and understood.
