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.

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 lesson has been designed to cover the content of specification point 4.1.2.1 (Chromosomes) and 4.1.2.2 (Mitosis and the cell cycle) of the AQA GCSE Biology and Combined Science course. Cell division is a topic which can cause students a number of problems so this lesson has been designed to ensure that the key details are covered and checked constantly. As well as the understanding and previous knowledge checks, quiz competitions are written into the lesson to maintain engagement and motivation.
The lesson begins with the introduction of the term cell cycle and students will learn that the cycle consists of three stages. The key details of each of these stages is covered during the main part of the lesson so that students can meet the specification requirements of being able to describe the main events. Time is allotted for discussion to encourage students to converse about important points such as what happens to the replicated chromosomes during mitosis to enable identical daughter cells to be produced. Opportunities are taken to make links to other topics such as animal and plant cells as students are challenged to recall the functions of some sub-cellular structures. The final part of the lesson involves a series of summary questions which challenges the students to not only recall content but also to apply to unfamiliar organisms and it is not until the final question that they will answer a question about the cell cycle in humans.
This fully-resourced lesson has been designed to cover both the foundation and higher tier content of specification point 5.3.2 (Control of blood glucose concentration) as found in topic 5 of the AQA GCSE Biology & Combined Science specifications. This resource contains an engaging PowerPoint (37 slides) and accompanying worksheets, some of which have been differentiated so that students of different abilities can access the work.
The resource is filled with a wide range of activities, each of which has been designed to engage and motivate the students whilst ensuring that the key Biological content is covered in detail. Understanding checks are included throughout so that the students can assess their grasp of the content. In addition, previous knowledge checks make links to content from earlier topics such as the endocrine system and literacy checks ensure that the students can spell and recognise the key words, which is extremely important considering how many terms begin with the letter g in this homeostatic control system.
The following content is covered in this lesson:
The receptors, coordination centre and effectors in the control of blood glucose concentration
The release of insulin when high blood glucose levels are detected
The conversion of glucose to glycogen for storage in liver and muscle cells
The causes and treatments of diabetes type I and II
The release of glucagon when low blood glucose levels are detected
The interaction of insulin and glucagon in a negative feedback cycle
As stated at the top, this lesson has been designed for GCSE-aged students who are studying the AQA GCSE Biology or Combined Science courses, but it can be used with A-level students who need to go back over the key points before looking at the homeostatic control in more detail
This lesson has been designed to cover the content as detailed in point 5.2.1 (The structure and function of the human nervous system) of the AQA GCSE Biology & Combined Science specifications. Consisting of a detailed and engaging PowerPoint (38 slides) and accompanying worksheets, the range of activities will motivate the students whilst ensuring that the content is covered in detail. Students will learn how receptors, sensory neurones, the CNS, motor neurones and effectors are involved in the detection and response to a stimulus. Reflex reactions are also considered and discussed so that students can recognise how these automatic and rapid responses avoid damage and pain to humans. Progress checks are included throughout the lesson so that students can assess their understanding of the content and any misconceptions can be addressed whilst quiz competitions, like FROM NUMBERS 2 LETTERS and YOU DO THE MATH, are used to introduce new terms and important values in a fun and memorable way.
This lesson has been written for GCSE-aged students who are studying the AQA GCSE Biology or Combined Science specifications but can be used with older students who need to know the key details of the nervous system for their A level course before taking it to greater depths
This lesson has been designed to cover the content as detailed in points 2.15, 2.16 and 2.17 (The eye as a sensory receptor and the correction of eye defects) of the Edexcel GCSE Biology specification. Consisting of a detailed and engaging PowerPoint (54 slides) and accompanying worksheets, the range of activities will motivate the students whilst ensuring that the content is covered in detail. Students will learn how the structures of the eye enable it to function as a sensory receptor, with a particular focus on the role of the cornea, lens, iris and the rod and cone cells in the retina. In addition, students will understand how eye defects such as short-sightedness and cataracts can cause problems for vision and can be corrected. Progress checks are included throughout the lesson so that students can assess their understanding of the content and any misconceptions can be addressed whilst quiz competitions are used to introduce new terms in a fun and memorable way.
This lesson has been written for GCSE-aged students who are studying the Edexcel GCSE Biology specification but can be used with younger students who have a real interest in this sensory receptor as well as older students who need to know the key details for their A level course.
This resource has been designed to cover the higher tier content of specification point 7.8 as detailed in the Edexcel GCSE Biology & Combined Science specifications. The lesson takes the format of a day at a fertility clinic and students will see how three couples, who are at different stages of their currently unsuccessful journey to getting pregnant, are advised and the treatments that could be on offer to them. Discussion points are included throughout the lesson to encourage the students to talk about the Biology and to allow any misconceptions to be addressed if and when they arise. In addition, previous knowledge checks are regular so that the links between this topic and earlier ones such as the hormones in the menstrual cycle and contraception can be made.
Students will be introduced to the abbreviation ART before learning how clomifene is used to treat infertility in women do not ovulate. Time is taken to explore alternative fertility drugs and students are challenged to explain why FSH and LH would be the reproductive hormones contained in these substances. The main focus of the lesson is IVF treatment and the main task culminates with students gaining a number of key points in the for and against argument before being challenged to continue this as a set homework in the form of an evaluation. Quiz competitions are used to introduce key terms in a fun and memorable way and the final task is a mathematical skills check where students will be able to compare the high number of multiple births that are associated with this treatment as compared to the number from natural births.
This lesson has been designed for students studying the Edexcel GCSE Biology or Combined Science course but is also suitable for older students who are looking at this topic
This resource has been designed to cover the higher tier content of specification point 5.3.6 as detailed in the AQA GCSE Biology & Combined Science specifications. The lesson takes the format of a day at a fertility clinic and students will see how three couples, who are at different stages of their currently unsuccessful journey to getting pregnant, are advised and the treatments that could be on offer to them. Discussion points are included throughout the lesson to encourage the students to talk about the Biology and to allow any misconceptions to be addressed if and when they arise. In addition, previous knowledge checks are regular so that the links between this topic and earlier ones such as the hormones in human reproduction and contraception can be made.
Students will learn how a fertility drug may be made available and will be challenged to explain why FSH and LH would be the reproductive hormones contained in these substances.

This lesson has been designed for students studying the AQA GCSE Biology or Combined Science course but is suitable for older students who are looking at this topic.
This is a fully-resourced lesson consisting of an engaging PowerPoint and differentiated worksheets which have been designed to cover the content of points 7.15 & 7.16 as detailed on the Edexcel GCSE Biology & Combined Science specifications. This point states that students should be able to describe the cause of diabetes type I and II and describe how they are both controlled. There are links made throughout the lesson between this topic and the control of blood glucose concentration from specification point 7,13 and 7.14
The lesson has been designed to take the format of a diabetic clinic where the students perform the duties of the attending doctor. They will move through the different expectations of the role which includes identifying symptoms, diagnosis of type I or II and communication with the patients to reveal the findings. The wide range of activities will enable the students to learn how to spot that someone is suffering from diabetes and the similarities and differences between the different types so they can determine which one is being presented. The summary tasks challenge the students to construct a letter to a patient who is suffering from type II and to identify the correct type from another doctor’s letter.
Understanding and previous knowledge checks are interspersed with quiz competitions, like the one shown in the cover image, which make the learning fun and memorable and enable the students to assess their progress.
This lesson has been designed for students studying the Edexcel GCSE Biology or Combined Science course but is suitable for both younger and older students who are focusing on this disease
This is a detailed lesson resource that covers the content of point 5.1.3 (a) of the OCR A-level Biology A specification which states that students should be able to demonstrate and apply their understanding of the roles of mammalian sensory receptors. There is a particular focus on the Pacinian corpuscle to demonstrate how these receptors act as transducers by converting one form of energy into electrical energy which is then conducted as an electrical impulse along the sensory neurone.
The lesson begins by looking at the different types of stimuli that can be detected. This leads into a written task where students have to form sentences to detail how thermoreceptors, rods and cones, hair cells in the inner ear and vibration receptors in the cochlea convert different forms of energy into electrical energy. Students will be introduced to the term transducer and will be challenged to work out what these cells carry out by using their sentences. As stated above, students will meet a Pacinian corpuscle and learn that this receptors detects pressure changes in the skin using the concentric rings of connective tissue in its structure. The rest of the lesson focuses on how ions are involved in the maintenance of resting potential and then depolarisation. Time is taken to look into the key details of these two processes so students are confident with this topic when met again during a lesson on the generation of action potentials. All of the tasks are differentiated to allow students of different abilities to access the work. As well as understanding checks to allow the students to assess their progress against the current topic, there are also a number of prior knowledge checks on topics like inorganic ions and methods of movement.
This lesson has been designed for students studying the OCR A-level Biology course
This fully-resourced lesson covers the content of the first part of specification point 6.2.2 of the AQA A-level Biology specification that states that students should be able to describe the detailed structure of a cholinergic synapse and a neuromuscular junction and be able to compare the transmission across both of these structures. The majority of the lesson uses the cholinergic synapse as the example but other neurotransmitters and drugs are considered so students are prepared to describe the differing effects on the synapse.
The lesson begins by using a version of the WALL (as shown in the cover image) which asks the students to group 12 words into three groups of 4. Not only will this challenge their prior knowledge from topics earlier in this module but it will also lead to the discovery of four of the structures that are found in a synapse. Moving forwards, students are introduced to aectylcholine as the neurotransmitter involved at cholinergic synapses and they will start to add labels to the structures found in the pre-synaptic bulb. Time is taken to focus on certain structures such as the voltage gated channels as these types of channel were met previously when looking at the depolarisation of a neurone. There is plenty of challenge and discovery as students are pushed to explain why organelles like mitochondria would be found in large numbers in the bulb. With this process being a cascade of events, a bullet point format is used to ensure that the key content is taken in by the students and again key points like exocytosis and the action of acetylcholinesterase are discussed further. The next part of the lesson challenges the application aspect of the specification as students are introduced to unfamiliar situations in terms of synapses with new drugs like MDMA and are asked to work out and explain how these affect the nervous transmission. The final part of the lesson focuses on the NMJ and challenges the students to use the knowledge gained from earlier in the lesson to develop their understanding of these junctions. Time is taken to look at the structure of the sarcolemma to enable students to understand how the binding of the acetylcholine leads to the wave of depolarisation passing to the transverse tubules.
Understanding checks and prior knowledge checks are included throughout the lesson so that students can not only assess their progress against the current topic but also see whether they can make links to earlier topics.
This lesson has been designed for students studying the AQA A-level Biology course but could be used with very able GCSE students who are keen to develop their understanding of synapses over and above the small detail that is provided at that level. This lesson also ties in nicely with the other uploaded lessons from topic 6
This is a highly-detailed and fully-resourced lesson which covers the detail of specification point 5.1.2 (d) of the OCR A-level Biology A specification which states that students should be able to demonstrate and apply an understanding of the roles of the hypothalamus, posterior pituitary, ADH and the collecting duct in the control of the water potential of the blood. Students learnt about the principles of homeostasis and negative feedback in an earlier module, 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 and this task is differentiated so those who need extra assistance can still access the work.
This lesson has been written for students studying on the OCR A-level Biology A course and ties in nicely with the other uploaded lessons in module 5.1.2 which include the structure of the nephron, ultrafiltration and selective reabsorption.
This fully-resourced lesson explores the contributions of the chromosome mutations that arise during meiosis to genetic variation. The engaging PowerPoint and accompanying worksheets have been designed and written to cover the part of point 4.3 of the AQA A-level Biology specification which states that students should be able to describe how mutations in the numbers of chromosomes can arise spontaneously and significantly contribute to evolution.
Over the course of the lesson, students will encounter a number of chromosome mutations but the main focus is chromosome non-disjunction and they will learn that this can result in Down, Turner’s and Klinefelter’s syndromes. Students are guided through a description of the formation of gametes and zygotes with abnormal numbers of chromosomes before being challenged to describe the formation of a zygote with Turner’s syndrome. The key aspects of meiosis, which are taught in a future lesson, are introduced and related to the lead up to the change in chromosome number. Inversion, translocation, duplication and deletion are also introduced and links are made to other topics such as regulatory sequences and gene expression.
This fully-resourced lesson has been designed to cover point 8.4 of the Pearson Edexcel A-level Biology A (Salters Nuffield) specification that states that students should know the structures and function of synapses in nerve impulse transmission. The majority of the lesson uses the cholinergic synapse as the example but other neurotransmitters are considered to provide the students with a wider view of this topic and to make links to specification point 8.15

Understanding checks and prior knowledge checks are included throughout the lesson so that students can not only assess their progress against the current topic but also see whether they can make links to earlier topics.
This fully-resourced lesson looks at how heart rate is controlled by the cardiovascular control centre in the medulla oblongata. The engaging and detailed PowerPoint and accompanying resources have been designed to cover the first part of point 7.9 (ii) of the Pearson Edexcel A-level Biology A (Salters Nuffield) specification but also ties in well with previously covered topics and provides a good introduction to control systems which are covered later in topic 7 and 8.
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. This allows the SAN to be recalled as this structure play an important role as the effector in this control system. Moving forwards, the three key parts of a control system are recalled as the next part of the lesson will specifically look at the range of sensory receptors, the coordination centre and the effector. Students are introduced to chemoreceptors and baroreceptors 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 control and this task has been differentiated three ways to allow differing abilities to access the work
This engaging lesson looks at the myogenic nature of cardiac muscle and explores the roles of the SAN, AVN, Bundle of His and Purkyne fibres in the normal electrical activity of the heart. The PowerPoint and accompanying resources have been designed to cover the points 7.8 (i & ii) of the Pearson Edexcel A-level Biology A (Salters Nuffield) 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 the myogenic tissue in a wave of excitation. The lesson has been written to make clear links to the cardiac cycle and the structure of the heart and students are challenged on their knowledge of this system from topic 1. 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 so that the contraction of the ventricles can happen from the bottom upwards. The structure of the cardiac muscle cells is discussed and the final task of the lesson challenges the students to describe the conducting tissue, with an emphasis on the use of key terminology
Due to the detailed nature of this lesson, it is estimated that it will take about 2 hours of A-level teaching time to cover the two specification points
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 point 7.10 (i) of the Pearson Edexcel A-level Biology A (Salters Nuffield) 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, myofilament and myosin can be introduced. Students should have met these terms as well as actin when learning about the sliding filament theory in topic 7.2, so this acts as a recall. 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 clear and concise lesson looks at the calculation of cardiac output as the product of stroke volume and heart rate. This engaging PowerPoint and accompanying resource have both been designed to cover point 7.9 (i) of the Pearson Edexcel A-level Biology A (Salters Nuffield) specification which states that students should be able to calculate cardiac output.
The lesson begins by challenging the students to recall that the left ventricle is the heart chamber with the thickest myocardial wall. This leads into the introduction of stroke volume as the volume of blood which is pumped out of the left ventricle each heart beat. A quick quiz game is used to introduce a normative value for the stroke volume and students are encouraged to discuss whether males or females would have higher values and to explain why. A second edition of this quiz reveals a normative value for resting heart rate and this results into the introduction of the equation to calculate cardiac output. A series of questions are used to challenge their ability to apply this equation and percentage change is involved as well. The final part of the lesson looks at the hypertrophy of cardiac muscle and students will look at how this increase in the size of cardiac muscle affects the three factors and will be challenged to explain why with reference to the cardiac cycle that was covered in an earlier topic.
This fully-resourced lesson looks at the roles of glycolysis in aerobic and anaerobic respiration and explains how the sequence of reactions results in glucose being converted to pyruvate. The engaging PowerPoint and accompanying differentiated resources have been designed to cover point 7.4 of the Pearson Edexcel A-level Biology A (Salters Nuffield) specification.
The lesson begins with the introduction of the name of the stage and then explains how the phosphorylation of the hexoses and the production of the ATP, coenzymes and pyruvate are the stages that need to be known for this specification. Time is taken to go through each of these stages and key points such as the use of ATP in phosphorylation are explained so that students can understand how this affects the net yield. A quick quiz competition is used to introduce NAD and the students will learn that the reduction of this coenzyme, which is followed by the transport of the protons and electrons to the cristae for the electron transport chain is critical for the overall production of ATP. Understanding checks, in a range of forms, are included throughout the lesson so that students can assess their progress and any misconceptions are immediately addressed.
This lesson has been written to tie in with the other uploaded lessons on the Link reaction, Krebs cycle, oxidative phosphorylation and the production of lactate.
This detailed lesson looks at the structure and function of the motor neurones that form the autonomic nervous system and is responsible for automatic responses. The engaging PowerPoint and accompanying resource have both been designed to cover the second part of point 5.1.5 (g) of the OCR A-level Biology A specification which states that students should be able to demonstrate and apply their knowledge and understanding of the functional organisation of the motor system into somatic and autonomic systems. Students will discover that this system is further divided into sympathetic and parasympathetic systems to control different aspects of a particular involuntary response.
The lesson begins with a focus on the types of effectors that will be connected to the CNS by autonomic motor neurones. Students will learn that effectors which are not under voluntary control such as cardiac muscle, smooth muscle and glands will be innervated by these neurones. Moving forwards, a quick quiz competition is used to introduced ganglia as a structure which connects the two or more neurones involved in the cell signalling between the CNS and the effector. This leads into the discovery of the two divisions and students will begin to recognise the differences between the sympathetic and parasympathetic systems based on function but also structure. The remainder of the lesson looks at the differing effects of these two systems.
This lesson has been written to tie in with the lesson on the organisation of the mammalian nervous system which covers the first part of specification point 5.1.5 (g)
