A Science teacher by trade, I've also been known to be found teaching Maths and PE! However, strange as it may seem, my real love is designing resources that can be used by other teachers to maximise the experience of the students. I am constantly thinking of new ways to engage a student with a topic and try to implement that in the design of the lessons.

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
This detailed lesson describes the specific stages of the aerobic energy system and has been designed for the OCR A-level PE course. In line with the specification content in “Energy systems and ATP resynthesis”, the lesson describes the type of reaction, the sites of the specific stages within the system, the fuel used, the controlling enzymes, the ATP yield and the bi-products.
The lesson begins by introducing the aerobic system as the system that becomes the dominant energy provider after the ATP-PC and glycolytic system. Students are challenged to recognise that this system 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 SYSTEM SAFE” where the teams of students compete to recall the quantitative values associated with this topic.
This detailed lesson introduces ATP as the body’s energy store and energy currency and introduces PC, glycogen and fat are sources for energy transfer to re-synthesise ATP during exercise. The engaging PowerPoint has been designed to cover the “Energy transfer in the body” section of topic 1.1.6 as detailed in the AQA 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 and glycogen are sources of energy transfer in the anaerobic systems and glucose and fats are sources for the aerobic system. Key details about each of these sources are provided and explained and links are made to upcoming lessons on the energy systems. 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 anaerobic and aerobic energy systems.
This lesson describes the active loading of sucrose at the source and movement by mass flow to the sink down the hydrostatic pressure gradient. Both the detailed PowerPoint and accompanying resources have been designed to cover points 7.2 (g, h & i) as detailed in the CIE International A-level Biology specification.
The lesson begins by challenging the students to recognise the key term translocation when it is partially revealed and then the rest of the lesson focuses on getting them to understand how this process involves the mass flow of assimilates down the hydrostatic pressure gradient from the source to the sink. It has been written to tie in with 7.1 (d) where the structure of the phloem tissue was initially introduced and the students are continually challenged on their prior knowledge. A step-by-step guide is used to describe how sucrose is loaded into the phloem at the source by the companion cells. Time is taken to discuss key details such as the proton pumping to create the proton gradient and the subsequent movement back into the cells by facilitated diffusion using co-transporter proteins. Students will learn that the hydrostatic pressure at the source is high, due to the presence of the water and sucrose as cell sap, and that this difference when compared to the lower pressure at the sink leads to the movement along the phloem.
A number of quick quiz rounds are included in the lesson to maintain engagement and to introduce key terms and the lesson concludes with a game of SOURCE or SINK as students have to identify whether a plant structure is one or the other (or both)
This fully-resourced lesson looks at the detailed structure of a muscle fibre, and focuses on the proteins, bands and zones that are found in the myofibril. The engaging PowerPoint and acccompanying resource have been designed to cover the third part of point E2 in UNIT 2 of the Pearson BTEC Level 3 National Diploma in Sport and Exercise Science 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 fully-resourced lesson describes how the different properties of water make this biological molecule incredibly important in Biology. The engaging PowerPoint and accompanying worksheets have been designed to cover point 1.7 of the AQA A-level Biology specification.
Hydrolysis reactions have been a recurring theme throughout topic 1, so the start of this lesson challenges the students to recognise the definition when only a single word is shown: water. Students will also recall the meaning of a condensation reaction. Moving forwards, the rest of the lesson focuses on the relationship between the structure and properties of water, beginning with its role as an important solvent. The lesson has been specifically written to make links to future topics and this is exemplified by the transport of water along the xylem in plants. A quick quiz round is used to introduce cohesion and tension so students can understand how the column of water is able to move along this vascular tissue without interruption. The next section focuses on the high latent heat of vaporisation and heat capacity of water and these properties are put into biological context using thermoregulation and the maintenance of a stable environment for aquatic animals. The lesson finishes with an explanation of the polar nature of water, a particularly important property that needs to be well understood for a number of upcoming topics, such as cell membranes.
Some of the key biological topics are covered in topic 2 of the Pearson Edexcel A-level Biology A (Salters Nuffield) course and include the transport of materials across cell membranes, DNA structure and replication, protein synthesis and monohybrid inheritance. In line with this, many hours of intricate planning have gone into the design of all of the 19 lessons that are included in this bundle to ensure that the content is covered in detail, understanding is constantly checked to immediately address misconceptions and that engagement is high. This is achieved through the wide variety of tasks in the PowerPoints and accompanying worksheets which include exam-style questions with clear answers, discussion points, differentiated tasks and quick quiz competitions.

This fully-resourced lesson describes the use of vaccinations to protect individuals and populations and the differences between active and passive immunity. The engaging PowerPoint and accompanying resources have been designed to cover the fourth part of point 2.4 of the AQA A-level Biology specification and there is also a description and discussion on the concept of herd immunity.
The previous lesson finished with a series of exam questions where students observed differences between the primary and secondary immune responses so the start of this lesson uses an imaginary game of TOP TRUMPS to challenge them on the depth of their understanding. This will act to remind them that a larger concentration of antibodies is produced in a quicker time in the secondary response. The importance of antibodies and the production of memory cells for the development of immunity is emphasised and this will be continually referenced as the lesson progresses. The students will learn that this response of the body to a pathogen that has entered the body through natural processes is natural active immunity. Moving forwards, time is taken to look at vaccinations as an example of artificial active immunity. Another series of questions focusing on the MMR vaccine will challenge the students to explain how the deliberate exposure to antigenic material activates the immune response and leads to the retention of memory cells. A quick quiz competition is used to introduce the variety of forms that the antigenic material can take along with examples of diseases that are vaccinated against using these methods. The eradication of smallpox is used to describe the concept of herd immunity and the students are given time to consider the scientific questions and concerns that arise when the use of this pathway is a possible option for a government. The remainder of the lesson looks at the different forms of passive immunity and describes the drawbacks in terms of the need for a full response if a pathogen is reencoutered.
This detailed lesson describes the structure and properties of the cell membrane, focusing on the phospholipid bilayer and membrane proteins. Fully resourced, the PowerPoint and accompanying worksheets have been designed to cover the first part of point 2.3 of the AQA A-level Biology specification and clear links are made to Singer and Nicholson’s fluid mosaic model
The fluid mosaic model is introduced at the start of the lesson so that it can be referenced at appropriate points throughout the lesson. Students were introduced to phospholipids in topic 1 and so an initial task challenges them to spot the errors in a passage describing the structure and properties of this molecule. This reminds them of the bilayer arrangement, with the hydrophilic phosphate heads protruding outwards into the aqueous solutions on the inside and the outside of the cell. In a link to some upcoming lessons on the transport mechanisms, the students will learn that only small, non-polar molecules can move by simple diffusion and that this is through the tails of the bilayer. This introduces the need for transmembrane proteins to allow large or polar molecules to move into the cell by facilitated diffusion and active transport. Proteins that act as receptors as also introduced and an opportunity is taken to make a link to an upcoming topic so that students can understand how hormones or drugs will bind to target cells in this way. Moving forwards, the structure of cholesterol is covered and students will learn that this hydrophobic molecule sits in the middle of the tails and therefore acts to regulate membrane fluidity. The final part of the lesson challenges the students to apply their newly-acquired knowledge to a series of questions where they have to explain why proteins may have moved when two cells are used and to suggest why there is a larger proportion of these proteins in the inner mitochondrial membrane than the outer membrane.
This fully-resourced lesson describes the modes of action of the T and B lymphocytes in the immune response. The detailed PowerPoint and accompanying resources have been designed to cover point 2.4 of the CIE A-level Biology specification and the structure of antibodies and the roles of memory cells is also briefly introduced.
Antigen presentation was introduced at the end of the previous lesson so the task at the start of this lesson challenges students to recognise the name of this process and then they have to spot the errors in the passage that describes the details of this event. This reminds them that contact between the APC and T lymphocytes is necessary to elicit a response which they will come to recognise as the cellular response. A series of quick quiz rounds reveals key terms in a memorable way and one that is introduced is helper T cells. Time is then taken to describe the importance of cell signalling for an effective response and students will learn how the release of chemicals by these cells activates other aspects of the response. The role of the killer T cells is also described before an exam-style question is used to check on their understanding at this point of the lesson. This leads into the section of the lesson that deals with the humoral response and students will understand how this involves the antibodies that are produced by the plasma cells that are the result of clonal selection and expansion. The remainder of the lesson focuses on the role of the antibodies and the attachment of phagocytes to opsonins.

This fully-resourced lesson describes how mutations, the events of meiosis and random fertilisation result in genetic variation. The engaging PowerPoint and accompanying resources have been primarily designed to cover points 8.1 (i) & (ii) of the Edexcel A-level Biology B specification but also includes activities to challenge the students on previous concepts in topics 1 and 2.
The students begin the lesson by having to identify phenotype and species from their respective definitions so that a discussion can be encouraged where they will recognise that phenotypic variation within a species is due to both genetic and environmental factors although this lesson only focuses on the genetic aspect. A range of activities, which include exam-style questions and quick quiz rounds, are used to challenge the students on their knowledge and understanding of substitution mutations, deletions, insertions, the genetic code, crossing over and independent assortment. Moving forwards, the concept of multiple alleles is introduced and students will learn how the presence of more than 2 alleles at a locus increases the number of phenotypic variants. The final section of the lesson focuses on the production of haploid gametes by meiosis and discusses how the random fertilisation of these gametes during sexual reproduction further increases variation.
This fully-resourced lesson guides students through the use of the Hardy-Weinberg equation to monitor changes in allele frequencies in a population. The detailed PowerPoint and differentiated practice questions worksheets have been designed to cover point 8.3 (iv) of the Edexcel A-level Biology B specification
The lesson begins with a focus on the equation to ensure that the students understand the meaning of each of the terms. The recessive condition, cystic fibrosis, is used as an example so that students can start to apply their knowledge and assess whether they understand which genotypes go with which term. Moving forwards, a step-by-step guide is used to show students how to answer a question. Tips are given during the guide so that common misconceptions and mistakes are addressed immediately. The rest of the lesson gives students the opportunity to apply their knowledge to a set of 3 questions, which have been differentiated so that all abilities are able to access the work and be challenged
This detailed lesson describes how the movement of water molecules by osmosis can affect both plant and animal cells. Both the PowerPoint and accompanying resources have been designed to cover specification point 2.1.5 (e) [i] as detailed in the OCR A-level Biology A specification and there is a particular focus on solutions of different water potentials.
It’s likely that students will have used the term concentration in their osmosis definitions at GCSE, so the aim of the starter task is to introduce water potential to allow students to begin to recognise osmosis as the movement of water molecules from a high water potential to a lower potential, with the water potential gradient. Time is taken to describe the finer details of water potential to enable students to understand that 0 is the highest value (pure water) and that this becomes negative once solutes are dissolved. Exam-style questions are used throughout the lesson to check on current understanding as well as prior knowledge checks which make links to previously covered topics such as the lipid bilayer of the cell membrane. The remainder of the lesson focuses on the movement of water when animal and plant cells are suspended in hypotonic, hypertonic or isotonic solutions and the final appearance of these cells is described, including any issues this may cause.
This lesson has been specifically written to tie in with the previous two lessons covering 2.1.5 (b) & (d) where the cell membrane, diffusion and active transport were described.
This fully-resourced lesson describes how natural selection leads to behavioural, anatomical and physiological adaptations. The PowerPoint and accompanying resources have been designed to cover specification points 4.3 & 4.4 of the Pearson Edexcel A-level Biology A specification
President Trump’s error ridden speech about antibiotics is used at the beginning of the lesson to remind students that this is a treatment for bacterial infections and not viruses as he stated. Moving forwards, 2 quick quiz competitions are used to introduce MRSA and then to get the students to recognise that they can use this abbreviation to remind them to use mutation, reproduce, selection (and survive) and allele in their descriptions of evolution through natural selection. The main task of the lesson challenges the students to form a description that explains how this strain of bacteria developed resistance to methicillin to enable them to see the principles of natural selection. This can then be used when describing how the anatomy of the modern-day giraffe has evolved over time. The concept of convergent evolution is introduced and links are made to the need for modern classification techniques as this is covered later in topic 4. Moving forwards, students will understand how natural selection leads to adaptations and a quick quiz competition introduces the different types of adaptation and a series of tasks are used to ensure that the students can distinguish between anatomical, behavioural and physiological adaptations. The Marram grass is used to test their understanding further, before a step by step guide describes how the lignified cells prevent a loss of turgidity. Moving forwards, the students are challenged to explain how the other adaptations of this grass help it to survive in its environment. A series of exam-style questions on the Mangrove family will challenge them to make links to other topics such as osmosis and the mark schemes are displayed to allow them to assess their understanding. The final part of the lesson focuses on the adaptations of the anteater but this time links are made to the upcoming topic of taxonomy so that students are prepared for this lesson on species and classification hierarchy.
Due to the extensiveness of this lesson and the detail contained within the resources, it is estimated that it will take in excess of 2 hours of allocated A-level teaching time to deliver this lesson.
This fully-resourced lesson describes the relationship between the structure, properties and functions of triglycerides in living organisms. The engaging PowerPoint and accompanying worksheets have been designed to cover the first part of point (f) as detailed in AS unit 1, topic 1 of the WJEC A-level Biology specification and links are also made to related future topics such as the importance of the myelin sheath for the conduction of an electrical impulse which is covered in A2.
The lesson begins with a focus on the basic structure and roles of lipids, including the elements that are found in this biological molecule and some of the places in living organisms where they are found. Moving forwards, the students are challenged to recall the structure of the carbohydrates from earlier in topic 1 so that the structure of a triglyceride can be introduced. Students will learn that this macromolecule is formed from one glycerol molecule and three fatty acids and have to use their understanding of condensation reactions to draw the final structure. Time is taken to look at the difference in structure and properties of saturated and unsaturated fatty acids and students will be able to identify one from the other when presented with a molecular formula. The final part of the lesson explores how the various properties of a triglyceride mean that it has numerous roles in organisms including that of an energy store and source and as an insulator of heat and electricity.
