This engaging lesson covers the biological classification of a species, phylogenetic classification and the use of the binomial naming system. The PowerPoint and accompanying resources have been designed to cover point 4.5 of the AQA A-level Biology specification which is titled species and taxonomy. The lesson begins by looking at the meaning of a population in Biology so that the term species can be introduced. A hinny, which is the hybrid offspring of a horse and a donkey, is used to explain how these two organisms must be members of different species because they are unable to produce fertile offspring. Although the art of courting might be lost on humans in the modern world, the marabou stork is used as an example to show how courtship behaviour is an essential precursor to successful mating in most organisms. Students are encouraged to discuss other examples of courtship behaviour, such as the release of pheromones and birdsong, so that their knowledge and understanding is broad. Moving forwards, students will learn that species is the lowest taxon in the modern-day classification hierarchy. A quiz runs throughout the lesson and this particular round will engage the students whilst they learn the names of the other 7 taxa and the horse and the donkey from the earlier example are used to complete the hierarchy. Students will understand that the binomial naming system was introduced by Carl Linnaeus to provide a universal name for each species and they will be challenged to apply their knowledge by completing a hierarchy for a modern-day human, by spotting the correct name for an unfamiliar organism and finally by suggesting advantages of this system. The final part of the lesson briefly looks at how advances in genome sequencing and the comparison of common biological molecules has allowed the relationships between organisms to be clarified. This is a detailed lesson and it is estimated that it will take around 2 hours of A-level teaching time to cover the content and therefore this specification point.

This lesson is fully-resourced, engaging and detailed and explains how the Contact process is one of the 3 steps involved in making sulfuric acid. The PowerPoint and accompanying resources, which are differentiated, have been written to cover point C6.1(d) of the OCR Gateway A GCSE Chemistry specification. The lesson begins with a challenge where students have to use the 1st letters of the answers to questions on previously covered topics to come up with the word CONTACT. At this point, the students are introduced to the contact process as the 2nd step in a 3 stage process to make sulfuric acid. The lesson goes through the details of each of the 3 steps but particular time is spent exploring the conditions needed for the contact process in step 2. Students are continuously tested on their knowledge of reversible reactions and the key concepts to do with equilibrium position and equilibrium yield are explained so they can understand how the conditions of 2 atmospheres and 450 degrees celsius are chosen. Again through a prior knowledge check of empirical formula, the students will be introduced to vanadium oxide as the catalyst. As well as exam-style questions with displayed answers to check on current understanding, there are discussion points as well as quick quiz competitions to introduce key terms and values in a memorable way.

This fully-resourced lesson explains how gel electrophoresis is used to analyse nucleic acids and proteins and explores its applications in forensic science and medical diagnosis. The engaging and detailed PowerPoint and accompanying resource have been written to cover point 19.1 (d) of the CIE International A-level Biology specification As a whole lesson, each step of the genetic fingerprinting process is covered but with the main focus on gel electrophoresis within this process. Students will be introduced to STRs and will come to recognise their usefulness in human identification as a result of the variability between individuals. Moving forwards, the involvement of the PCR and restriction enzymes are discussed and students are challenged on their knowledge of this process and these substances as they were encountered in a previous lesson. The main section of the lesson focuses on the use of gel electrophoresis to separate DNA fragments (as well as proteins) and the key ideas of separation due to differences in base pair length or molecular mass are discussed and explained. As well as current understanding checks, an application question involving Huntington’s disease is used to challenge their ability to apply their knowledge of the process to an unfamiliar situation. The remainder of the lesson describes how the DNA is transferred to a membrane and hybridisation probes are used to create a pattern on the X-ray film. Time has been taken to make continuous links to the previous lessons in topic 19.1 as well as those from topic 6 where DNA, RNA and protein synthesis were introduced.

This is a fully-resourced lesson which uses exam-style questions, engaging quiz competitions, quick tasks and discussion points to challenge students on their understanding of the content of topics B1 - B4, that will assessed on PAPER 1. It has been specifically designed for students on the AQA 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 key points of each of the sub-topics are embedded. The lesson has been written to take place in numerous shops that could be found on the high street to allow the following sub-topics to be covered: Eukaryotes and prokaryotes The prefixes of size and converting between units The cell structures of animal and plant cells Mitosis and the cell cycle Benign and malignant tumours The principles of organisation The structure of the heart and the circulatory system The features of the alveoli which enable efficient gas exchange CHD The risk factors of non-communicable diseases Pathogens as microorganisms that cause infectious diseases Bacterial, viral, fungal and protist diseases Vaccinations Temperature and photosynthesis Enzymes The digestive system The role of bile The functions of the components of blood 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 extra support 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 calculating percentage change 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 competitions, quick tasks and discussion points to challenge students on their understanding of the content in topics C1 - C4, that will assessed on PAPER 3. It has been specifically designed for students on the 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 cover as many sub-topics as possible, but the following have been given particular attention: The relative mass and charge of protons, electrons and neutrons Using the Periodic table to calculate numbers of the sub-atomic particles Writing elements and compounds in chemical symbol equations Simple and giant covalent structures Explaining the difference in conductivity of graphite and diamond Drawing dot and cross diagrams for ionic compounds The transfer of electrons during the formation of an ionic bond Writing chemical formulae for ionic compounds Conservation of mass and balancing symbol equations Calculating the relative formula mass Electrolysis of molten salts and aqueous solutions Extraction of metals 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 extra support 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 drawing dot and cross diagrams, diamond and graphite and writing chemical formulae. Due to the extensiveness of this revision lesson, it is estimated that it will take in excess of 3/4 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 3 exam.

This fully-resourced lesson has been written to prepare students for the range of mathematical-based questions that they may face on the two OCR GCSE Chemistry papers. The lesson has been designed to contain a wide range of activities which includes 8 quiz competition rounds spread across the duration of the lesson to maintain engagement whilst the students assess their understanding. The mathematical skills covered in this lesson include: Calculating the number of sub-atomic particles in atoms and ions Writing chemical formulae for ionic compounds Identifying isotopes Using Avogadro’s constant to calculate the number of particles Calculating the relative formula mass Calculating amount in moles using the mass and the relative formula mass Balancing chemical symbol equations Calculating reacting masses Gas calculations using molar volume Calculating concentration of solutions Titration calculations Deducing the empirical formula Calculating energy changes in reactions Most of the resources have been differentiated two ways to allow students of differing abilities to access the work whilst still being challenged. In addition, step by step guides are used to demonstrate how to carry out some of the more difficult calculations such as the harder mole calculations and calculating masses in reactions This lesson could be used with higher ability students on the OCR GCSE Combined Science course by taking out the sections which are not applicable.

This detailed lesson describes how aerobic glycolysis, the Krebs cycle and the electron transport chain produce energy for sport and exercise. The engaging PowerPoint and accompanying resource have been designed to cover the 4th part of point A7 in UNIT 1 of the Pearson BTEC Level 3 National Diploma in Sport and Exercise Science specification which states that students should understand how these stages produce energy as well as the role of the mitochondria. The lesson has been written to include a wide range of tasks which include exam-style questions and discussion points to check on understanding and quiz competitions to introduce key terms and values in a memorable way and to maintain engagement and motivation. There is a focus on the link between each stage and the next and the location in a cell where each one occurs. Due to the extensiveness of this lesson, it is estimated that it will take in excess of 2 teaching hours to cover the detail within this resource

This is a fully-resourced lesson which describes the relationship between cardiac output, stroke volume and heart rate and explains how they differ between rest and during exercise. The PowerPoint and accompanying resources have been designed to cover the 5th point in SECTION 9 of the CIE International A-level PE specification. The lesson begins by challenging the students to recognise that the left ventricle has the most muscular wall of all of the heart chambers. This allows the stroke volume to be introduced as the volume of blood ejected from the left ventricle each heart beat and then a quiz competition is used to introduce normative values for the stroke volume and the heart rate. Moving forwards, students will learn that the cardiac output is the product of the stroke volume and the heart rate. The main part of the lesson looks at the adaptation of the heart to aerobic training in the form of cardiac hypertrophy and then the students are challenged to work out how this would affect the stroke volume, the cardiac output and the resting heart rate. A number of tasks are used to get the students to explain why the resting heart rate decreases and to calculate the changes in cardiac output. One of the two tasks has been differentiated and this allows students of differing abilities to access the work.

This fully-resourced lesson describes how the heart rate is regulated during exercise by the cardiovascular centre in the medulla oblongata. The engaging and detailed PowerPoint and accompanying resources, which are differentiated 3 ways, have been designed to cover the final specification point of the “Cardiovascular system during exercise” topic in unit 1.1.b of the OCR A-level PE specification. This lesson begins with a prior knowledge check where students have to identify and correct any errors in a passage about the conduction system of the heart which was covered in an earlier lesson in topic 1.1.b. This allows the SAN to be recalled as this structure plays an important role as the effector in this regulatory system. Moving forwards, the three key parts of a regulatory system are introduced as the next part of the lesson will specifically look at the range of sensory receptors, the regulatory centre and the effector. A quick quiz round is used to introduce a range of stimuli so that students can understand how chemoreceptors, proprioceptors and baroreceptors generate electrical impulses to be conducted along a neurone to the brain. Another quick quiz introduces the medulla oblongata as the location of the cardiovascular centre. The communication between this centre and the SAN through the autonomic nervous system can be poorly understood so detailed explanations are provided and the sympathetic and parasympathetic divisions are compared. The final task challenges the students to demonstrate and apply their understanding by writing a detailed description of the regulation and this task has been differentiated three ways to allow differing abilities to access the work
