This is a fully-resourced lesson which describes and explains how cardiac hypertrophy affects the cardiac output, stroke volume and resting heart rate. The lesson has been specifically designed to cover the first part of point C4 in UNIT 1 of the Pearson BTEC Level 3 National Diploma in Sport and Exercise Science 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 the function and anatomy of the heart as well as the associated blood vessels. Both the engaging PowerPoint and accompanying differentiated resources have been designed to cover the 1st part of point B1 in UNIT 2 of the Pearson BTEC Level 3 National Diploma in Sport and Exercise Science specification The structure of the heart is a topic which was covered in part at GCSE so this lesson has been written to build on that prior knowledge. The main task of the lesson involves students labelling the different structures as they are recalled. Time is taken at different points of the lesson to look at some of the structures and concepts in further detail. For example, students will learn that humans have a double circulatory system and that the thicker muscular wall of the left ventricle allows the blood in the systemic circulation to be at a higher pressure than in the pulmonary circulation. Students are also challenged to explain why a hole in the septum would cause health issues for an affected individual and this links back to previous work in unit 1 on energy systems. They will also learn how the chordae tendineae are pulled taut by the papillary muscles to prevent the inversion of the valves By the end of the lesson, the students will be able to identify the following structures and describe their individual functions: right and left atria right and left ventricles septum tricuspid and bicuspid valve semi-lunar valves chordae tendineae pulmonary artery and pulmonary vein vena cava aorta A number of quiz rounds are used throughout the lesson to introduce key terms in a fun and memorable way before the final round is used as a final check so they can assess whether they can recognise the structures and recall their functions.

Disaccharides are formed from the condensation of two monosaccharides and this lesson describes the formation of maltose, sucrose and lactose. The concise PowerPoint and accompanying question sheet have been designed to cover the third part of points 1.12 & 1.13 of the Pearson Edexcel A-level Biology A specification but also continually links to the previous lesson on monosaccharides when considering the different components of these three disaccharides. The first section of the lesson focuses on a prefix and a suffix so that the students can recognise that the names of the common disaccharides end in -ose. In line with this, a quick quiz round is used to introduce maltose, sucrose and lactose before students are challenged on their prior knowledge as they have to describe how condensation reactions and the formation of glycosidic bonds were involved in the synthesis of each one. The main task of the lesson again challenges the students to recall details of a previous lesson as they have to identify the monomers of each disaccharide when presented with the displayed formula. Time is taken to show how their knowledge of these simple sugars will be important in later topics such as extracellular enzymes, translocation in the phloem and the control of gene expression as exemplified by the Lac Operon. The lesson finishes with two exam-style questions where students have to demonstrate and apply their newly acquired knowledge

This lesson explains how to calculate the net primary productivity by subtracting a plant’s respiratory losses from the gross primary productivity. The PowerPoint and accompanying resources have been designed to cover points 5.9 (i) and (ii) of the Edexcel International A-level Biology specification. Due to the fact that the productivity of plants is dependent on photosynthesis, a series of exam-style questions have been written into the lesson which challenge the students to explain how the structure of the leaf as well as the light-dependent and light-independent reactions are linked to GPP. All of the exam questions have displayed mark schemes which are included in the PowerPoint to allow students to immediately assess their understanding. A number of quick quiz competitions as well as guided discussion points are used to introduce the formulae to calculate NPP and N and to recognise the meaning of the components. Once again, this is immediately followed by the opportunity to apply their understanding to selected questions

This lesson describes the role of the posterior pituitary gland and ADH in the homeostatic balance of blood water potential. The PowerPoint and accompanying resources have been designed to cover specification points (f & g) in topic 7 of A2 unit 3 of the WJEC A-level Biology specification. Students learnt about the principles of homeostasis and negative feedback in an earlier lesson in this topic, so this lesson acts to build on that knowledge and challenges them to apply their knowledge. A wide range of activities have been included in the lesson to maintain motivation and engagement whilst the understanding and prior knowledge checks will allow the students to assess their progress as well as challenge themselves to make links to other Biology topics. The lesson begins with a discussion about how the percentage of water in urine can and will change depending on the blood water potential. Students will quickly be introduced to osmoregulation and they will learn that the osmoreceptors and the osmoregulatory centre are found in the hypothalamus. A considerable amount of time is taken to study the cell signalling between the hypothalamus and the posterior pituitary gland by looking at the specialised neurones (neurosecretory cells). Links are made to the topics of neurones, nerve impulses and synapses and the students are challenged to recall the cell body, axon and vesicles. The main section of the lesson forms a detailed description of the body’s detection and response to a low blood water potential. The students are guided through this section as they are given 2 or 3 options for each stage and they have to use their knowledge to select the correct statement. The final task asks the students to write a detailed description for the opposite stimulus

This fully-resourced lesson describes the roles of the SAN, AVN, bundle of His and Purkyne fibres in the neural control of the cardiac cycle. The engaging PowerPoint and accompanying resources have been designed to cover the second part of point B3 in UNIT 2 of the Pearson BTEC Level 3 National Diploma in Sport and Exercise Science The lesson begins with the introduction of the SAN as the natural pacemaker and then time is given to study each step of the conduction of the impulse as it spreads away from this node in a wave of excitation. The lesson has been written to make clear links to the cardiac cycle (which was covered in the previous lesson) and to the structure of the heart and students are challenged on their knowledge of this system. Moving forwards, students are encouraged to consider why a delay would occur at the AVN and then they will learn that the impulse is conducted along the Bundle of His to the apex before being conducted on the Purkyne fibres so that the contraction of the ventricles can happen from the bottom upwards. The final task of the lesson challenges the students to describe the conducting tissue, with an emphasis on the use of key terminology

This lesson describes the key events of the eukaryotic cell cycle and specifically focuses on those that occur in interphase. The PowerPoint and accompanying resources have been designed to cover point (a) in topic 6 of AS unit 1 of the WJEC A-level Biology specification and also introduces the stages of mitosis and cytokinesis to prepare students for the upcoming lesson on the significance of this type of cell division. The students were introduced to the cell cycle at GCSE so this lesson has been planned to build on that knowledge and to emphasise that the M phase which includes mitosis (nuclear division) only occupies a small part of the cycle. The students will learn that interphase is the main stage and that this is split into three phases, G1, S and G2. A range of tasks which include exam-style questions, guided discussion points and quick quiz competitions are used to introduce key terms and values and to describe the main processes that occur in a very specific order. Extra time is taken to ensure that key terminology is included and understood, such as sister chromatid and centromere, and this focus helps to show how it is possible for genetically identical daughter cells to be formed at the end of the cycle.

This detailed lesson explains how five different sources are used in the energy production for sport and exercise. The engaging PowerPoint has been written to cover the first 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 know how stored ATP, phosphocreatine, blood glucose, glycogen and fatty acids are energy sources. Time is taken to go through each of the five energy sources and to explain how they are used to produce or re-synthesise ATP. Students will understand how the different sources are used during different parts of exercise. A series of 5 quiz rounds is used to introduce important words and values in a memorable way to try to increase the likelihood of them being recalled.

This fully-resourced lesson describes the roles of the SAN, AVN, bundle of His and Purkyne fibres in the neural control of the cardiac cycle. The engaging PowerPoint and accompanying resources have been designed to cover the third point of section A9 as detailed in the CIE International A-level PE specification The lesson begins with the introduction of the SAN as the natural pacemaker and then time is given to study each step of the conduction of the impulse as it spreads away from this node in a wave of excitation. The lesson has been written to make clear links to the cardiac cycle (which will be covered in the next lesson) and to the structure of the heart and students are challenged on their knowledge of this system. Moving forwards, students are encouraged to consider why a delay would occur at the AVN and then they will learn that the impulse is conducted along the Bundle of His to the apex before being conducted on the Purkyne fibres so that the contraction of the ventricles can happen from the bottom upwards. The final task of the lesson challenges the students to describe the conducting tissue, with an emphasis on the use of key terminology

This fully-resourced lesson looks at the regulation of the heart rate by the cardiovascular centre in the medulla oblongata. The engaging and detailed PowerPoint and accompanying resources have been designed to cover the sixth point of SECTION A9 of Applied Anatomy and Physiology as detailed in the CIE International A-level PE specification. This lesson focuses on the neural and hormonal factors involved. 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 A9. 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. Students are introduced to chemoreceptors and baroreceptors, as well as receptors in the muscles, and time is taken to ensure that the understanding of the stimuli detected by these receptors is complete and that they recognise the result is the conduction of an impulse along a neurone to the brain. A quick quiz is used to introduce 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 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

This detailed lesson describes the characteristics and physiology of the aerobic energy pathway and has been designed for the Edexcel A-level PE course. In line with specification point 1.4.4 & 1.4.5, the content of the lesson covers the ease and speed of ATP production and the intensity and duration of exercise which will be supported by the aerobic pathway when it is the dominant energy provider. The lesson begins by introducing the aerobic pathway as the pathway that becomes the dominant energy provider after the ATP-PC and glycolytic pathways. Students are challenged to recognise that this pathway supports lower intensity exercise but that it will support exercise for a much longer duration than the others, suggesting that it produces a high yield of ATP. The main part of the lesson looks at how this high yield of ATP is produced during glycolysis, the Krebs cycle and the electron transport chain and students will learn the location of each of these stages in the cell. Questions, discussion points and quiz competitions are included throughout the lesson and act as understanding checks to ensure that any misconceptions are addressed immediately. The final tasks of the lesson are a series of multiple choice questions and a quiz round called “UNLOCK THE AEROBIC PATHWAY SAFE” where the teams of students compete to recall the quantitative values associated with this topic.

This fully-resourced lesson describes the roles of the sinoatrial node (SAN) and the atrioventricular node (AVN) in the control of blood flow through the heart. The engaging PowerPoint and accompanying resources have been designed to cover the second part of point 1.2.5 as detailed in the Edexcel A-level PE specification and also includes the roles of the bundle of His and Purkyne fibres to enable students to get a full understanding. The lesson begins with the introduction of the SAN as the natural pacemaker and then time is given to study each step of the conduction of the impulse as it spreads away from this node in a wave of excitation. The lesson has been written to make clear links to the cardiac cycle (which is covered in an upcoming lesson) and to the structure of the heart and students are challenged on their knowledge of this system. Moving forwards, students are encouraged to consider why a delay would occur at the AVN and then they will learn that the impulse is conducted along the bundle of His to the apex before being conducted on the Purkyne fibres so that the contraction of the ventricles can happen from the bottom upwards. The final task of the lesson challenges the students to describe the conducting tissue, with an emphasis on the use of key terminology

This detailed lesson introduces ATP as the body’s energy store and explains how PC, glycogen and fat are sources for its re-synthesis during exercise. The engaging PowerPoint has been designed to cover the second part of point 1.4.3 as detailed in the Edexcel A-level PE specification. The lesson begins by challenging the students to recognise that the link between muscle contraction, active transport and the conduction of electrical impulses is the need for energy. A number of quick quiz competitions are used throughout the lesson to maintain engagement and to introduce key terms and values and the first quiz round will result in the students meeting adenosine tri-phosphate (ATP). Time is taken to describe the structure of this energy store and to explain how it will be broken down into ADP and a phosphate and that this mechanism results in the release of energy for muscle contraction. Importantly, students will learn that the ATP stored in muscles will only allow for the first few seconds of contraction and therefore if exercise and contraction are to continue, the ATP will need to be re-synthesised. The main part of the lesson explores how phosphocreatine, glycogen and fats are sources for this re-synthesis. Key details about each of these sources are provided and explained and links are made to upcoming lessons on the energy pathways as well as to topics already covered such as the different types of muscle fibres. The final round of the quiz, which is called “What’s your SOURCE?” acts a final understanding check as the teams of students have to recognise one of the 4 energy sources based on a description. This lesson has been specifically written to tie in with the next lessons on the ATP-PC, glycolytic and aerobic pathways.

This concise lesson describes the function of the cerebellum. The PowerPoint and accompanying resources are part of the 3rd lesson in a series of 17 lessons that cover the details of the brain and neuropsychology topic of the AQA GCSE Psychology specification. In the previous lesson, the students were introduced to the function of the lobes of the cerebral cortex and so the initial task challenges them to use that knowledge to learn the name of the cerebellum. The students will be able to locate this structure on a diagram. Moving forwards, the function of this brain structure as controlling balance, posture and fine movement is introduced and real life examples are given. As this is the last lesson on brain structure, the final part of the lesson uses a BLOCKBUSTERS quiz to challenge their understanding of the content of the first 3 lessons of this topic. This topic of the brain and neuropsychology has proved particularly difficult for the students in recent years, so I have taken time to analyse the lesson sequencing. There’s a lot of content to absorb and to understand before moving onto the next part, so I’ve tried to ensure that cross topics links and prior knowledge checks run throughout the lessons. I have organised the lessons to run through the biology content first before moving onto the psychology parts as shown by the 17 lessons below: #1 Organisation of the nervous system #2 The structure and function of the cerebral lobes #3 The cerebellum #4 The structure and function of the sensory and motor neurones #5 The relay neurones #6 Synaptic transmission #7 Excitation and inhibition at the synapse #8 The somatic nervous system #9 The autonomic nervous system #10 The fight or flight response #11 James-Lange theory of emotion #12 James-Lange theory of emotion part 2 #13 Penfield’s study of the interpretative index #14 Hebb’s theory of learning and neuronal growth #15 An introduction to neuropsychology #16 Brain scanning techniques #17 Tulving’s gold memory study

This concise lesson acts as an introduction to topic 5.3, Energy and Ecosystems, and describes how plant biomass is formed, measured and estimated. The engaging PowerPoint is the 1st in a series of 3 lessons which have been designed to cover the detailed content of topic 5.3 of the AQA A-level Biology specification. A quiz round called REVERSE Biology Bingo runs throughout the lesson and challenges students to recognise the following key terms from descriptions called out by the bingo caller: community ecosystem abiotic factor photosynthesis respiratory substrate biomass calorimetry The ultimate aim of this quiz format is to support the students to understand that any sugars produced by photosynthesis that are not used as respiratory substrates are used to form biological molecules that form the biomass of a plant and that this can be estimated using calorimetry. Due to the clear link to photosynthesis, a series of prior knowledge checks are used to challenge the students on their knowledge of this cellular reaction but as this is the first lesson in the topic, the final section of the lesson looks forwards and introduces the chemical energy store in the plant biomass as NPP and students will also meet GPP and R so they are partially prepared for the next lesson.

This engaging lesson looks at the structure of a muscle fibre, and focuses on the proteins, bands and zones that are found in the myofibril. The PowerPoint and acccompanying resource have been designed to cover the second part of points 1.3.5 & 1.3.6 of the Edexcel A-level PE specification. The lesson begins with an imaginary question from the quiz show POINTLESS, where students have to recognise a range of fields of study. This will reveal myology as the study of muscles so that key terms like myofibril and myosin can be introduced. Moving forwards, students will be shown the striated appearance of this muscle so they can recognise that some areas appear dark where both myofilaments are found and others as light as they only contain actin or myosin. A quiz competition is used to introduce the A band, I band and H zone and students then have to use the information given to label a diagram of the myofibril. The final task challenges the students to use their knowledge of the sliding filament theory to recognise which of these bands or zones narrow or stay the same length when muscle is contracted

This lesson describes the protective effect of a simple reflex, as exemplified by those which involve the sensory, relay and motor neurones. The PowerPoint and accompanying resources are part of the final lesson in a series of 3 lessons which have been planned to cover the content of point 6.1.1 of the AQA A-level biology specification, titled “Survival and response”. As shown on the cover image, the lesson begins with a challenge, where the students have to recognise the connection between key terms which have been grouped together. This will remind them of the names of three types of neurones, the three types of muscle tissue and some reflexes. Time is taken at the start to ensure that students understand that although the brain might be informed of a reflex, it isn’t involved in the processing to coordinate the movement. At the same time, the role of the other part of the CNS, the spinal cord in spinal reflexes, is emphasised. This lesson has been specifically planned to build on their knowledge of reflex actions from GCSE and to build in the detail that will support them in this lesson and as they move through the content of topic 6. Ultimately, students will understand how the rapid response of a simple reflex allows organisms to avoid damage and survive, due to the nervous pathway only consisting of three neurones, and therefore less synapses than other reactions. Understanding checks, in the form of exam-style questions are written into the lesson and the answers embedded into the PowerPoint to allow students to assess their progress against the current topic. The two other lessons in this series covering the detail of specification point 6.1.1 are named “responses in flowering plants” and “taxes and kineses”.

This fully-resourced lesson looks at the blood circulation in a mammal and considers how the pulmonary circulation differs from the systemic circulation. The engaging PowerPoint and accompanying resources have been designed to cover the third part of point 3.4.1 of the AQA A-level Biology specification The lesson begins with a focus on the double circulatory system and checks that students are clear in the understanding that the blood passes through the heart twice per cycle of the body. Beginning with the pulmonary circulation, students will recall that the pulmonary artery carries the blood from the right ventricle to the lungs. An opportunity is taken at this point to check on their knowledge of inhalation and the respiratory system as well as the gas exchange between the alveoli and the capillary bed. A quick quiz is used to introduce arterioles and students will learn that these blood vessels play a crucial role in the changes in blood pressure that prevent the capillaries from damage. When looking at the systemic circulation, time is taken to look at the coronary arteries and renal artery as students have to be aware of these vessels in addition to the ones associated with the heart. In the final part of the lesson, students are challenged to explain how the structure of the heart generates a higher pressure in the systemic circulation and then to explain why the differing pressures are necessary. This lesson has been written to tie in with the other uploaded lessons from topic 3.4.1 (mass transport in animals)

This lesson describes the biological meaning of species, populations, gene pool and allele frequency and explains how these terms are linked. The PowerPoint and accompanying resources are part of the 1st lesson in a series of 2 lessons that cover the detail of specification point 7.2 (Populations) of the AQA A-level biology. The two living species of the African elephant, the forest and bush elephant, are used as examples to demonstrate the meaning of species and to show how they exist as one or more populations. A quick quiz introduces the term gene pool in an engaging way and then the allele frequency of three versions of the GBA gene demonstrates how these frequencies can change in small populations. In doing so, students are briefly introduced to genetic drift which they will encounter in an upcoming topic. The students are challenged throughout the lesson with understanding checks and prior knowledge checks as well as exam-based questions where they have to comment on the validity of a scientist’s conclusion. The other lesson in topic 7.2 is the Hardy-Weinberg principle.

This lesson describes how iPS cells are formed from fibroblasts and discusses why this method is less controversial than the use of embryonic stem cells. The PowerPoint and accompanying resources are part of the 2nd lesson in a series of 2 lessons which covers the content of point 7.3 (stem cells) of the Edexcel A-level biology B specification. The lesson begins with a SPOT THE ERRORS task, where students have to use their knowledge of pluripotent cells from the previous lesson to identify the 3 errors and make corrections. The aim of this task is to remind them that pluripotent cells are found in embryos and can divide in unlimited numbers before finally becoming fully differentiated somatic cells. Moving forwards, the students are introduced to fibroblasts as examples of these somatic cells and the opportunity is taken to challenge their knowledge of collagen as this is a substance produced by these cells. The answers are embedded into the PowerPoint to allow the students to assess their recall of this topic 1 content. A quick quiz is used to introduce the acronym iPS and students will learn that fibroblasts can be reprogrammed to form induced pluripotent cells using specific transcription factors. The remainder of the lesson challenges them to answer questions about the use of iPS cells in regenerative medicine after reading a passage about an example. This allows them to recognise that deriving these cells from adult tissues as opposed to embryonic stem cells raises less problems and the transplant into the same person reduces the risk of rejection.
