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 lesson describes how the movement of growth factors regulates growth in response to directional stimuli, focusing on gravitropism and phototropism. The PowerPoint and accompanying resources are part of the 1st lesson in a series of 3, which have been designed to cover point 6.1.1 (Survival and response) of the AQA A-level biology specification.
The lesson begins with a prior knowledge check, where the students have to identify key terms encountered in topics 1 - 4, and use their 1st letters to form the term, stimuli. Students are reminded of the meaning of a stimulus, and this introduces the need for organisms to detect and respond to stimuli, to increase their chances of survival. This lesson focuses on these responses in flowering plants, and builds on any knowledge they may have gained at GCSE. They should have met auxins at this previous level, but will now be introduced to IAA, and will complete several tasks which check that they understand the key features of these chemicals, such as their location of production and method by which they move through the shoots and roots. The students are guided through the movement of IAA to the shaded side in a shoot during phototropism, and will learn how this uneven distribution leads to uneven growth. An exam-style question presents them with two further scenarios, where the tip of the shoot has been cut off or is covered, and the students need to describe and explain what will happen to the appearance of the shoot after a week. Moving forwards, the students will learn how the pumping of hydrogen ions into the cell wall and the activation of expansin proteins are involved in the cell elongation.
The remainder of the lesson discusses the response to gravity and explains how shoots and roots respond differently.
The lesson is full of understanding and prior knowledge checks and all answers are embedded into the PowerPoint.
The other two lessons in this series of 3 covering 6.1.1 describe taxes and kineses and the protective effect of a simple reflex.
This lesson has been designed to cover the content in points 7.11 and 7.12 of the Edexcel GCSE Biology specification which states that students should be able to explain how thermoregulation takes place, with particular reference to the role of the skin. This resource contains an engaging PowerPoint and a differentiated worksheet, which together use a wide range of activities to motivate the students and to engage them in the content matter.
The lesson begins by challenging the students to calculate a number from a series of biological based statements. This number is 37 which introduces the students to this temperature as the set-point at which homeostasis acts to maintain the body temperature. At this point of the lesson, a number of prior knowledge checks are used to challenge the students on their recall of the parts of a control system as well as challenging them to explain why temperatures above or below this set point can be problematic for body reactions. The main part of the lesson goes through the steps in the body’s detection and response to an increase in temperature and students will be introduced to the range of structures involved. Time is taken to focus on the role of the skin as an effector and key details about vasodilation and the production of sweat are discussed at length. The final task challenges the students to use all of the information from earlier in the lesson to write a detailed description of how the body detects and responds to a decrease in temperature.
This lesson has been written for students studying on the Edexcel GCSE Biology course but is also suitable for older students who are studying thermoregulation and need to recall the key details.
This engaging and fully-resourced lesson describes the relationship between the structure of the chloroplast and its role as the site of photosynthesis. The PowerPoint and accompanying resources have been designed to prepare the students for topic 5.1 (Photosynthesis) of the AQA A-level Biology course
Students were introduced to the cell structures in eukaryotic cells in topic 2.1 so this lesson has been written to build on that knowledge. A version of the quiz show POINTLESS runs throughout the lesson and this maintains engagement whilst challenging the students to recall the parts of the chloroplast based on a description which is related to their function. The following structures are covered in this lesson:
double membrane
thylakoids (grana)
stroma
intergranal lamellae
starch grains
chloroplast DNA and ribosomes
Once each structure has been recalled, a range of activities are used to ensure that key details are understood such as the role of the thylakoid membranes in the light-dependent reactions and the importance of ATP and reduced NADP for the reduction of GP to TP in the Calvin cycle.
This lesson has been specifically written to prepare students for the upcoming lessons on the light-dependent and light-independent reactions
This lesson describes the key events that occur during interphase, mitosis and cytokinesis in the eukaryotic cell cycle. The PowerPoint and accompanying resources have been designed to cover point 5.1 [c] of the CIE A-level Biology specification and challenges the students on their knowledge of chromosomes from an earlier lesson as well as preparing them for upcoming lessons on the main stages of mitosis and its significance in life cycles
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. There is also a focus on the checkpoints, such as the restriction point that occurs before the S phase to ensure that the cell is ready for DNA replication. 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. Important details of mitosis are introduced so students are ready for the next lesson, before the differences in cytokinesis in animal and plant cells are described.
This concise lesson has been written to cover specification point 5.1.1 (d) of the OCR A-level Biology A specification which states that students should be able to apply an understanding of the behavioural responses in temperature control in ectotherms. The main aim when designing the lesson was to support students in making sensible and accurate decisions when challenged to explain why these types of organisms have chosen to carry out a particular response. A wide range of animals are used so students are engaged in the content matter and are prepared for the unfamiliar situations that they will encounter in the final exam. Time is also taken to compare ectotherms against endotherms so that students can recognise the advantages and disadvantages of ectothermy.
This lesson has been written for A-level students studying on the OCR A-level Biology A course. Lessons on temperature control in endotherms and the principles of homeostasis and cell signalling, which are also in module 5.1.1, are also available so please download those too as they will allow students to make connections between one lesson, the previous and the next.
Water is very important for living organisms because of its numerous properties and this lesson focuses on its role as a solvent in transport. The engaging and detailed PowerPoint and accompanying worksheet have been designed to cover point 1.2 of the Pearson Edexcel A-level Biology A specification and also explains the importance of the dipole nature for this role in transport.
A mathematical theme runs throughout the lesson as students have to match the numbers calculated in the starter task to water statistics, such as the percentage of the volume of blood plasma that is water. This has been included to try to increase the relevance of each property so that it can be described in a biological context. Time is taken at the beginning of the lesson to describe the structure of water in terms of the covalent bonds between the oxygen and hydrogen atoms as well as the hydrogen bonds which form between molecules because of its polarity. Students will understand how water is a solvent which means that it is critical for transport in animals, a topic covered in the next few lessons but also for transport in plants as discussed in topic 4. The high heat capacity and latent heat of vaporisation of water is also discussed and explained through the examples of thermoregulation and the maintenance of a stable environment for aquatic animals. The final part of the lesson focuses on the involvement of water in condensation and hydrolysis reactions, two reactions which must be well understood for topic 1 and 2 and the formation and breakage of polysaccharides, lipids, polypeptides and polynucleotides.
This lesson has been designed to act as an introduction to the anatomy of the kidney before students move on to study each structure of the nephron in more detail. The lesson considers both the gross anatomy, in terms of the renal cortex and medulla and then looks at the functional unit of the nephron. The function of the different parts of the nephron are briefly discussed and the features that relate to function are considered.
This lesson has been designed for A-level students but could be used with higher ability GCSE students.
This detailed lesson has been written to cover the part of specification point 6.4.3 of the AQA A-level Biology specification which states that students should be able to describe how the structure of the nephron allows for the formation of glomerular filtrate. The aim of the design was to give the students the opportunity to discover the function of ultrafiltration and to be able to explain how the mechanisms found in the glomerulus and the Bowman’s capsule control the movement of small molecules out of the blood plasma. Key terminology is used throughout and students will learn how the combination of the capillary endothelium and the podocytes creates filtration slits that allow glucose, water, urea and ions through into the Bowman’s capsule but ensure that blood cells and plasma proteins remain in the bloodstream. A number of quiz competitions are used to introduce key terms and values in a fun and memorable way whilst understanding and prior knowledge checks allow the students to assess their understanding of the current topic and to challenge themselves to make links to earlier topics. The final task of the lesson challenges the students to apply their knowledge by recognising substances found in a urine sample that shouldn’t be present and to explain why this would cause a problem
This lesson has been written for students studying on the AQA A-level course and ties in nicely with the other kidney lessons on the structure of the nephron, selective reabsorption and osmoregulation
This is a fully-resourced and engaging REVISION LESSON which challenges the students on their knowledge and understanding of the topic 2 content (Biological molecules) of the CIE International A-level Biology specification. This topic isn’t always well understood by students so the lesson has been designed to include a wide range of activities that include differentiated exam questions, quick tasks and quiz competitions which will engage the students whilst they assess their progress. It has been designed to cover as much of the specification as possible but the following sub-topics have received particular attention:
Formation of polysaccharides by glycosidic bonds between monomers
Recognising monosaccharides, disaccharides and polysaccharides
The structure of starch and glycogen in relation to their function as stores and providers of energy
Water as a solvent with a high specific heat capacity and a high specific latent heat of vaporisation
Structure and bonding in proteins
The structure of globular and fibrous proteins as demonstrated by haemoglobin and collagen
The structure and function of cellulose
Links are made to other topics so that students are able to see how questions can include parts from different Biological concepts.
This lesson describes the light-independent reactions of photosynthesis as reduction of carbon dioxide using the products of the light-dependent reactions. The detailed PowerPoint and accompanying resources have been designed to cover point 5.8 (i) of the Pearson Edexcel A-level Biology A (Salters-Nuffield) specification and therefore describes carbon fixation in the Calvin cycle and the roles of GP, GALP, RuBP and RUBISCO).
The lesson begins with an existing knowledge check where the students are challenged to recall the names of structures, substances and reactions from the light-dependent stage in order to reveal the abbreviations of the main 3 substances in the light-independent stage. This immediately introduces RuBP, GP and GALP and students are then shown how these substances fit into the cycle. The main section of the lesson focuses on the three phases of the Calvin cycle and time is taken to explore the key details of each phase and includes:
The role of RUBISCO in carbon fixation
The role of the products of the light-dependent stage, ATP and reduced NADP, in the reduction of GP to GALP
The use of the majority of the GALP in the regeneration of RuBP
A step-by-step guide, with selected questions for the class to consider together, is used to show how 6 turns of the cycle are needed to form the GALP that will then be used to synthesise 1 molecule of glucose. A series of exam-style questions are included at appropriate points of the lesson and this will introduce limiting factors as well as testing their ability to answer questions about this stage when presented with an unfamiliar scientific investigation. The mark schemes are included in the PowerPoint so students can assess their understanding and any misconceptions are immediately addressed.
This lesson has been specifically written to tie in with the previous lessons on the structure of a chloroplast and the light-dependent reactions as well as the upcoming lesson on the products of the light-independent reactions.
This fully-resourced lesson looks at the structures of the sensory, relay and motor neurones and explains how the presence of a myelin sheath increases the speed of conduction of an impulse. The engaging PowerPoint and accompanying resources have been designed to cover point 8.1 of the Pearson Edexcel A-level Biology A (Salters Nuffield) specification which states that students should be able to apply their understanding of the structures and functions of sensory, relay and motor neurones as well as the differences between myelinated and unmyelinated neurones. This lesson also covers 8.2 (i) as the students will be able to see how conduction along a motor neurone stimulates effectors to respond to a stimulus. The PowerPoint has been designed to contain a wide range of activities that are interspersed between understanding and prior knowledge checks that allow the students to assess their progress on the current topics as well as challenge their ability to make links to topics from earlier in the modules. Quiz competitions like SAY WHAT YOU SEE are used to introduce key terms in a fun and memorable way.
The students will be able to compare these neurones based on their function but also distinguish between them based on their structural features. Time is taken to look at the importance of the myelin sheath for the sensory and motor neurones. Students will be introduced to the need for the entry of ions to cause depolarisation and will learn that this is only possible at the nodes of Ranvier when there is a myelin sheath. Key terminology such as saltatory conduction is introduced and explained. The final task involves a comparison between the three neurones to check that the students have understood the structures and functions of the neurones.
Throughout the lesson, links are made to related topics such the organisation of the nervous system and students will be given additional knowledge such as the differences between somatic and autonomic motor neurones.
This lesson describes how to use the Spearman’s rank correlation to analyse the relationships between the distribution of species and abiotic and biotic factors. The PowerPoint and accompanying exam-style question are the first lesson in a series of 2 which have been designed to cover point 18.1 (e) of the CIE A-level Biology specification and challenges the students on their knowledge of the t-test as covered in topic 17 as well as preparing students for the next lesson on the use of the Pearson’s linear correlation formula.
As with the lessons on the t-test and Simpson’s index of diversity, a step by step guide is used to walk the students through the use of the formula to generate the rank coefficient and to determine whether there is a positive correlation, no correlation or a negative correlation. The students are also reminded of the null hypothesis and will be shown how to accept or reject this hypothesis and to determine significance. The students will work through an example with the class and then are given the opportunity to apply their newly-acquired knowledge to an exam-style question which assesses whether there is a relationship between light intensity and % plant cover in a habitat. The mark scheme is displayed on the PowerPoint so the students can assess their understanding and address any misconceptions that may arise
This lesson describes the roles of the hypothalamus, posterior pituitary, ADH and collecting ducts in osmoregulation. The PowerPoint and accompanying resources have been planned to cover the content of point (8) of topic 14.1 of CIE A-level biology specification (for assessment in 2025-27).
Students covered the principles of homeostasis and negative feedback in the first 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 and this task is differentiated so those who need extra assistance can still access the work.
This fully-resourced lesson describes how the cells of multicellular organisms are specialised for particular functions and organised into tissues, organs and organ systems. The detailed and engaging PowerPoint and accompanying resources have been designed to cover points 2.1.6 (h, i, j and k) of the OCR A-level Biology A specification and also describes how stem cells differentiate, including the production of erythrocytes (red blood cells) and neutrophils.
The start of the lesson focuses on the difference in the SA/V ratio of an amoeba and a human in order to begin to explain why the process of differentiation is critical for multicellular organisms. Students will discover that a zygote is a stem cell which can express all of the genes in its genome and divide by mitosis. Time is then taken to introduce gene expression as this will need to be understood in the later topics of the course. Moving forwards, the lesson uses the process of haematopoiesis from haematopoietic stem cells to demonstrate how the red blood cell and neutrophil differ significantly in structure despite arising from the same cell along the same cell lineage. A series of exam-style questions will not only challenge their knowledge of structure but also their ability to apply this knowledge to unfamiliar situations. These differences in cell structure is further exemplified by the epithelial cells of the respiratory tract and students will understand why the shape and arrangement of these cells differ in the trachea and alveoli in line with function. The link between specialised cells and tissues is made at this point of the lesson with these examples of epithelium and students will also see how tissues are grouped into organs and then into organ systems.
The remainder of the lesson focuses on specialised plant cells and the differing shapes and features of the palisade and spongy mesophyll cells and the guard cells are covered at length and in detail. Step by step guides will support the students so that they can recognise the importance of the structures and links are made to upcoming topics such as the vascular tissues so that students are prepared for these when covered in the future.
This fully-resourced lesson describes the relationship between the structure and properties of triglycerides and considers their roles in living organisms. The engaging PowerPoint and accompanying worksheets have been designed to cover the first part of point 1.3 of the AQA 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.
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 topic 1.2 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.
This fully-resourced lesson has been written to cover the content as detailed in specification point 1.1 (Sub-cellular structures of eukaryotic and prokaryotic cells) of the Edexcel GCSE Biology & Combined Science specifications. The lesson includes a detailed and engaging PowerPoint (63 slides) which contains a wide range of activities, each of which has been designed to motivate the students whilst covering the content in detail. At the completion of the lesson, students will know the sub-cellular structures that are found in bacterial, animal and plant cells and understand how the presence of these structures relates to the function of these cells. Understanding checks are written into the lesson at regular points so that students can constantly assess their understanding of this specification point and quiz competitions like “FROM NUMBERS 2 LETTERS” and “THE BIG REVEAL” introduce key terms to the students in an interesting and memorable way.
This lesson has been designed for GCSE-aged students studying the Edexcel course but is also suitable for younger students who want to learn about cells in more detail at KS3.
This lesson describes the importance of the cytoskeleton, and focuses on the role of these proteins in the transport within cells and cell movement. The PowerPoint and accompanying resource have been designed to cover point 2.1.1 (j) of the OCR A-level Biology A specification and has been specifically designed to tie in with
The previous lesson covered the ultrastructure of eukaryotic cells and the function of the different cellular components and this lesson has been planned to build on that knowledge to show how the cytoskeleton allows for the movement of these organelles from one part of the cell to another. In particular, the students will recognise how the dragging movement of the motor proteins along the microtubule track is important for the proteins produced at the RER to move to the Golgi before the vesicles are then moved to the membrane for exocytosis. In this way, this lesson also covers specification point 2.1.1 (i). Other examples such as the movement of the synaptic vesicles and the contraction of the spindle fibres during anaphase are used to consolidate understanding further. The cilia and the flagellum are also described and links are made to related topics such as the primary non-specific defences against pathogens.
In order to engage and motivate the students during the 7 lessons in this module, a running quiz competition has been written into each of the lessons and 3 rounds are incorporated into this lesson. A quiz scoresheet to keep track of the points is included in this resource.
This lesson has been designed to cover the detail of specification point 4.5.3.2 of the AQA GCSE Combined Science FOUNDATION TIER which states that students should be able to describe how the body detects and responds to an increase in blood glucose concentration. A considerable amount of time has been taken in the planning to ensure that the wide range of activities engages and motivates the students but that the key details are covered and understanding is checked and checked again.
The start of the lesson uses a range of prior knowledge checks and quiz competitions to answer the questions of what actually is glucose and why is it so important that the levels in the blood are controlled. Students are then introduced to glycogen and the fact that this carbohydrate can be stored is reiterated so that they can recognise how glucose must be converted into this substance to lower the blood concentration. Again, a quiz round is used to get them to recall that the pancreas will be the receptor and the liver will act as the effector. The main task of the lesson involves the formation of a bullet point answer where students are challenged to use the information from earlier in the lesson to complete this description.
