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 is a fully-resourced REVISION lesson which uses a range of exam questions, understanding checks, quick tasks and quiz competitions to enable students to assess their understanding of the content within topic 7 (Magnetism and electromagnetism) of the AQA GCSE Physics (8463) specification.
The specification points that are covered in this revision lesson include:
Poles of a magnet
Electromagnetism
Fleming’s left hand rule
Electric motors
Loudspeakers
Transformers
Of all of the Physics topics, this one tends to be one of the least well understood. Therefore, time has been taken to not only make this an engaging revision lesson but to go into detail on some of the topics which are commonly assessed in the exams.
This lesson can be used as revision resource at the end of the topic or in the lead up to mocks or the actual GCSE exams
This bundle contains 6 detailed revision resources which have been designed to challenge the students on their knowledge of the AQA GCSE Combined Science Trilogy Specification content that can be assessed in the 6 papers that they will sit whilst remaining engaged and motivated due to the wide range of activities. These activities include differentiated tasks, quiz competitions and exam questions with displayed answers.
All of the Powerpoint-based lessons are so detailed and extensive that they are likely to be used over the course of a number of lessons, allowing the teacher to focus on specific areas for part of all of a lesson. The papers covered by these resources are:
Paper 1: Biology topics B1 - B4
Paper 2: Biology topics B5 - B7
Paper 3: Chemistry topics C1 - C5
Paper 4: Chemistry topics C6-C10
Paper 5: Physics topics P1 - P4
Paper 6: Physics topics P5 - P7
This detailed lesson describes the pressure changes that occur during the cardiac cycle and explains how ECG traces can be interpreted. The PowerPoint and accompanying resources have been designed to cover points 4.4 (iii) & (v) of the Edexcel A-level Biology B specification and focuses on the importance of the valves in ensuring unidirectional movement of blood during the cycle.
The start of the lesson introduces the cardiac cycle as well as the key term systole, so that students can immediately recognise that the three stages of the cycle are atrial and ventricular systole followed by diastole. Students are challenged on their prior knowledge of the structure of the heart as they have to name and state the function of an atrioventricular and semi-lunar valve from an internal diagram. This leads into the key point that pressure changes in the chambers and the major arteries results in the opening and closing of these sets of valves. Students are given a description of the pressure change that results in the opening of the AV valves and shown where this would be found on the graph detailing the pressure changes of the cardiac cycle. They then have to use this as a guide to write descriptions for the closing of the AV valve and the opening and closing of the semi-lunar valves and to locate these on the graph. By providing the students with this graph, the rest of the lesson can focus on explaining how these changes come about. Students have to use their current and prior knowledge of the chambers and blood vessels to write 4 descriptions that cover the cardiac cycle. The final part of the lesson covers the changes in the volume of the ventricle.
The remainder of the lesson focuses on the ECG and explains how these traces can be interpreted to diagnose heart problems. A quiz competition is used to introduce the reference points of P, QRS and T on a normal sinus rhythm before time is taken to explain their representation with reference to the cardiac cycle. Moving forwards, a SPOT the DIFFERENCE task is used to challenge the students to recognise differences between sinus rhythm and some abnormal rhythms including tachycardia and atrial fibrillation. Bradycardia is used as a symptom of sinus node disfunction and the students are encouraged to discuss this symptom along with some others to try to diagnose this health problem.

This lesson describes the relationship between the size of an organism or structure and its surface to volume ratio. The PowerPoint and accompanying worksheets have been designed to cover point 3.1 of the AQA A-level Biology specification and also have been specifically planned to prepare the students for the upcoming lessons in topic 3 on gas exchange and absorption in the ileum.
The students are likely to have been introduced to the ratio at GCSE, but understanding of its relevance tends to be mixed. Therefore, real life examples are included throughout the lesson that emphasise the importance of the surface area to volume ratio in order to increase this relevance. A lot of students worry about the maths calculations that are associated with this topic so a step by step guide is included at the start of the lesson that walks them through the calculation of the surface area, the volume and then the ratio. Through worked examples and understanding checks, SA/V ratios are calculated for cubes of increasing side length and living organisms of different size. These comparative values will enable the students to conclude that the larger the organism or structure, the lower the surface area to volume ratio. A differentiated task is then used to challenge the students to explain the relationship between the ratio and the metabolic demands of an organism and this leads into the next part of the lesson, where the adaptations of larger organisms to increase the ratio at their exchange surfaces is covered. The students will calculate the SA/V ratio of a human alveolus (using the surface area and volume formulae for a sphere) and will see the significant increase that results from the folding of the membranes. This is further demonstrated by the villi and the microvilli on the enterocytes that form the epithelial lining of these folds in the ileum. The final part of the lesson introduces Fick’s law of diffusion so that students are reminded that the steepness of a concentration gradient and the thickness of a membrane also affect the rate of diffusion.
This lesson bundle contains 16 lessons which have been designed to cover the Edexcel International A-level Biology specification points which focus on the structure of DNA and RNA, their roles in replication and protein synthesis, and genetics and inheritance.

Factors affecting rates of reaction
Measuring rates of reaction
Reversible reactions
Changing the position of equilibrium
All of these lesson presentations and accompanying resources are detailed and engaging and contain regular progress checks to allow the students to constantly assess their understanding.
This lesson has been written with the aim of engaging students in the topic of simple and giant covalent molecules, as this is a topic which is often considered to be boring or is brushed over. A variety of tasks have been used to maintain the interest whilst ensuring that they key details and Science are known and understood.
The lesson begins with a quick recap task where students have to recognise a covalent bond from a description and fill the missing part. Moving forwards, they are introduced to the fact that covalent molecules can be simple or giant. They are then presented with a table showing some properties of covalent molecules and having to group them as simple or giant in the short space of time that the table remains displayed on the board. This task challenges their observational skills, something which will again be tested later in the lesson as they study the structure of graphite and diamond. Time is taken to ensure that key details such as the strong covalent bonds in both sets of molecules is understood and that it is the weak intermolecular forces which are actually responsible for the low melting and boiling points. The last part of the lesson introduces diamond and graphite as allotropes of carbon and students will briefly learn why one of these conducts electricity whilst the other doesn’t. If you want a lesson about these allotropes in more detail, then please look for “Diamond and Graphite”. Progress checks have been written into the lesson at regular intervals so that students are constantly assessing their understanding and so misconceptions are quickly identified.
This lesson has been written for GCSE students (14 - 16 years of age in the UK)
This lesson has been designed to guide GCSE students (14 - 16 year olds in the UK) through the steps involved in gas calculations. As you can see in the cover image, this lesson uses a step by step guide format to go through each of the critical stages. Hints and tips are given along the way and worked examples are used so that students can visualise how to set out their working. Important terminology such as room temperature and pressure (RTP) and limiting reactant are explained so that these do not cause issues. Students are given the opportunity to test their skills against some gas calculation questions which have detailed mark schemes and explanations to enable them to fully self-assess.
This fully-resourced REVISION lesson is detailed and engaging and uses a range of exam questions, understanding checks, quick tasks and quiz competitions to allow students to assess their understanding of the content within topic 7 (Radioactivity and particles) of the Pearson Edexcel IGCSE Physics 9-1 specification (4PH1) for first assessment in June 2019.
The specification points that are covered in this revision lesson include:
Describe energy transfers involving energy stores
Use the principle of conservation of energy
Know and use the relationship between efficiency, useful energy output and total energy output
Describe how thermal energy transfer may take place by conduction, convection and radiation
Explain ways of reducing unwanted energy transfer, such as insulation
Know and use the relationship between work done, force and distance moved in the direction of the force
Know and use the relationship between gravitational potential energy, mass, gravitational field strength and height
Know and use the relationship between kinetic energy, mass and speed
Understand how conservation of energy produces a link between gravitational potential energy, kinetic energy and work
Use the relationship between power, work done (energy transferred) and time taken
Describe the energy transfers involved in generating electricity using water, wind, geothermal resources, solar, fossil fuels and nuclear power
The students will thoroughly enjoy the range of activities, which include quiz competitions such as “The TRANSFER MARKET” where they have to compete to be the 1st to identify the type of energy transfer shown whilst all the time evaluating and assessing which areas of this topic will need their further attention. This lesson can be used as revision resource at the end of the topic or in the lead up to mocks or the actual International GCSE exams
An informative lesson presentation (37 slides) and associated question worksheet which looks at the key properties of alpha, beta and gamma radiation. Students are given key pieces of information during the lesson and are then challenged to use their knowledge of related topics such as atomic structure and waves to complete the information table about the types of radiation. By the end of the lesson, students will be able to compare the types of radiation on form, charge, relative mass, penetrating power and equation symbols. Progress checks have been written into the lesson at regular intervals so that students can constantly assess their understanding.
This lesson has been written for GCSE students (14 - 16 year olds in the UK).
A fast-paced lesson that looks at weight and how this differs on different planets depending upon the gravitational field strength. At the start of the lesson, the students are shown the equation to calculate gravity force and weight and are challenged to spot a difference (if there is one)! Time is then taken to explain how weight is the term used when a mass comes into the gravitational field of the Earth (or other planets). A quick understanding check, with the gravitational field strength Olympics, is used to see whether students can calculate this field and their mathematical skills are tested with a number of conversions needed to do so. Moving forwards, students are shown a number of masses and weights on the Earth and the Moon so they can see how mass does not change but weight will be different. The final task challenges them to apply their new-found knowledge to calculate their mass on the Earth, the Moon and Jupiter.
This lesson has been designed for GCSE students but it is suitable for KS3 students who are exploring the Universe topic.
An engaging and informative lesson presentation (49 slides) looks at the differences between contact and non-contact forces and focuses on enabling students to describe and recognise them. This lesson has been written for GCSE students but could be used in higher ability KS3 lessons with students who are looking to progress their knowledge.
The lesson begins by introducing the fact that forces can be grouped into these two categories and initial definitions are used to ease the students into the lesson. To follow on from this a competition called “FORCE it together” is used. This engaging game challenges the students to spot the name of a force which is in anagram form and then once it has been identified, they have to determine whether it would be a contact or non-contact force. As each force is met, key details are given and discussed. More time is given to areas which can cause problems for students, such as the use of weight and gravity force and whether they are actually different. Moving forwards, a rugby tackle is used to show the numerous forces that interact in everyday situations, before students are challenged to identify more forces in sports of their choice. Students will recall/learn that force is a vector quantity and therefore is represented in diagrams using arrows. Once again, this lesson focuses on showing them how these arrows can be used differently with the different types of forces. Students are briefly introduced to the idea of a free body diagram and an understanding check is used to see whether they can identify friction, gravity force and normal contact force from the arrows. Progress checks like this are written into the lesson at regular intervals, in a range of formats, so that students are constantly assessing their understanding. The final part of the lesson is one more quick competition where students have to use their knowledge of the forces to form words.
This fully-resourced lesson describes how enzyme and substrate concentration affect the rate of enzyme activity. The PowerPoint and accompanying resources are the last in a series of 3 lessons which cover the detail of point 1.5 (iv) of the Edexcel A-level Biology B specification.
The first part of the lesson describes how an increase in substrate concentration will affect the rate of reaction when a fixed concentration of enzyme is used. Time is taken to introduce limiting factors and students will be challenged to identify substrate concentration as the limiting factor before the maximum rate is achieved and then they are given discussion time to identify the possible factors after this point. A series of exam-style questions are used throughout the lesson and the mark schemes are displayed to allow the students to assess their understanding and for any misconceptions to be immediately addressed. Moving forwards, the students have to use their knowledge of substrate concentration to construct a graph to represent the relationship between enzyme concentration and rate of reaction and they have to explain the different sections of the graph and identify the limiting factors.
The final section of the lesson describes how the availability of enzymes is controlled in living organisms. Students will come to recognise that this availability is the result of enzyme synthesis and enzyme degradation and their recall of transcription and translation is tested through a SPOT the ERRORs task.
Please note that this lesson explains the Biology behind the effect of concentration on enzyme-controlled reactions and not the methodology involved in carrying out such an investigation as this is covered in a core practical lesson.
This detailed lesson describes how the ventilation rate is controlled by the ventilation centre in the medulla oblongata. The engaging PowerPoint and accompanying resource have been designed to cover the second part of point 7.13 (ii) in unit 5 of the Edexcel International A-level Biology specification.
The previous lesson described the control of heart rate so this lesson has been written to tie in with this and to use this knowledge to further the students understanding of the control of ventilation rate. The lesson begins with a focus on the muscles involved in ventilation, specifically the diaphragm and external intercostal muscles, so that students can understand how their contraction results in an increase in the volume of the thoracic cavity. Boyle’s law is briefly introduced to allow students to recognise the relationship between volume and pressure so that the movement of air with the pressure gradient can be described. Time is then taken to consider the importance of inhalation and an exam-style question challenges the students to explain that a constant supply of oxygen to the alveoli is needed to maintain a steep concentration gradient with the surrounding capillaries. The students are then tasked with writing a description of exhalation at rest using the description of inhalation as their guide. The rest of the lesson focuses on the mechanisms involved in increasing the rate and depth of breathing during exercise. Students will use their knowledge of the control of heart rate to recall that chemoreceptors detect changes in oxygen and carbon dioxide and blood pH and that the medulla oblongata processes the sensory information that it receives before coordinating a response. The final task challenges them to use the information provided in this lesson and the previous one to order 10 detailed descriptions so they can form a complete passage about this control system
This lesson describes the main stages of meiosis, focusing on the events which contribute to genetic variation and explains its significance in life cycles. The detailed PowerPoint and accompanying resources have been designed to cover points 2.1.6 (f) & (g) of the OCR A-level Biology A specification and includes description of crossing over, independent assortment, independent segregation and the production of haploid gametes
In order to understand how the events of meiosis like crossing over and independent assortment and independent segregation can lead to variation, students need to be clear in their understanding that DNA replication in interphase results in homologous chromosomes as pairs of sister chromatids. Therefore the beginning of the lesson focuses on the chromosomes in the parent cell and this first part of the cycle and students will be introduced to non-sister chromatids and the fact that they may contain different alleles which is important for the exchange that occurs during crossing over. Time is taken to go through this event in prophase I in a step by step guide so that the students can recognise that the result can be new combinations of alleles that were not present in the parent cell. Moving forwards, the lesson explores how the independent assortment and segregation of chromosomes and chromatids during metaphase I and II and anaphase I and II respectively results in genetically different gametes. The key events of all of the 8 phases are described and there is a focus on key terminology to ensure that students are able to describe genetic structures in the correct context. The final part of the lesson looks at the use of a mathematical expression to calculate the possible combinations of alleles in gametes as well as in a zygote following the random fertilisation of haploid gametes. Understanding and prior knowledge checks are interspersed throughout the lesson as well as a series of exam-style questions which challenge the students to apply their knowledge to potentially unfamiliar situations.
This lesson has been specifically planned to lead on from the previous two lessons on the cell cycle and the main stages of mitosis and constant references are made throughout to encourage students to make links and also to highlight the differences between the two types of nuclear division
This REVISION resource has been written with the aim of motivating the students whilst they are challenged on their knowledge of the content in Biology TOPIC 8 (Exchange and transport in animals) of the Edexcel GCSE Combined Science specification. The resource contains an engaging and detailed PowerPoint (90 slides) and accompanying worksheets, most of which are differentiated to allow all abilities to access the work.
The wide range of activities, which include exam questions and quiz competitions, have been designed to cover as much of topic 8 as possible but the following sub-topics have been given a particular focus:
Surface area to volume ratio
Gas exchange at the alveoli
The structure of the blood vessels
The gross structure of the heart and the major blood vessels
Calculating the cardiac output
The functions of the components of the blood
Aerobic vs anaerobic respiration
There is a large emphasis on mathematical skills in the new specification and these are tested throughout the lesson.
This resource is suitable for use at the end of topic 8, in the lead up to mocks or in the preparation for the final GCSE exams.
This engaging and fully-resourced lesson looks at how genetic drift can arise after a genetic bottleneck or as a result of the Founder effect. The detailed PowerPoint and accompanying resources have been designed to cover the second part of point 6.1.2 (e) of the OCR A-level Biology A specification which states that students should be able to demonstrate and apply an understanding of the factors that affect the evolution of a species.
A wide range of examples are used to show the students how a population that descends from a small number of parents will have a reduction in genetic variation and a change in the frequency of existing alleles. Students are encouraged to discuss new information to consider key points and understanding checks in a range of forms are used to enable them to check their progress and address any misconceptions. Students are provided with three articles on Huntington’s disease in South Africa, the Caribbean lizards and the plains bison to understand how either a sharp reduction in numbers of a new population beginning from a handful of individuals results in a small gene pool. Links to related topics are made throughout the lesson to ensure that a deep understanding is gained.
This lesson has been designed to tie in with another uploaded lesson on types of selection which is part of this specification point
This fully-resourced lesson explores how new species arise when changes in the gene pool of two populations prevents members from interbreeding and producing fertile offspring. The engaging PowerPoint and accompanying resources have been designed to cover the fifth part of point 7.3 of the AQA A-level Biology specification which states that students should be able to describe allopatric and sympatric speciation.
The lesson begins by using the example of a hinny, which is the hybrid offspring of a horse and a donkey, to challenge students to recall the biological classification of a species. Moving forwards, students are introduced to the idea of speciation and the key components of this process, such as isolation and selection pressures, are covered and discussed in detail. Understanding and prior knowledge checks are included throughout the lesson to allow the students to not only assess their progress against the current topic but also to make links to earlier topics in the specification. Time is taken to look at the details of allopatric speciation and how the different mutations that arise in the isolated populations and genetic drift will lead to genetic changes. The example of allopatric speciation in wrasse fish because of the isthmus of Panama is used to allow the students to visualise this process. The final part of the lesson considers sympatric speciation and again a wide variety of tasks are used to enable a deep understanding to be developed.
