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.
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.
An engaging lesson presentation (16 slides) which looks at the surface area to volume ratio and ensures that students can explain why this factor is so important to the organisation of living organisms. This is a topic which is generally poorly misunderstood by students and therefore time has been taken to design an engaging lesson which highlights the key points in order to encourage greater understanding.
The lesson begins by showing students the dimensions of a cube and two answers and challenges them to work out what the questions were that produced these answers. Students are shown how to calculate the surface area and the volume of an object before it is explained how this can then be turned into a ratio. Time is taken at this point to ensure that students can apply this new-found knowledge as they have to work out which of the three organisms in the “SA: V OLYMPICS” would stand aloft the podium. Students are given the opportunity to draw conclusions from this task so that they can recognise that the larger the organism, the lower the surface area to volume ratio. The lesson finishes by explaining how larger organisms, like humans, have adapted in order to increase the surface area at important exchange surfaces in their bodies.
There are regular progress checks throughout the lesson to allow the students to check on their understanding. This lesson has been written for GCSE students but is perfectly suitable for A-level students who want to look at this topic from a basic level
This clear and concise lesson explains how the inheritance of two or more genes that have loci on the same autosome demonstrates autosomal linkage. The engaging PowerPoint and associated resource have been designed to cover the part of point 6.1.2 (b[ii]) 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 use of phenotypic ratios to identify autosomal linkage.
This is a topic which can cause confusion for students so time was taken in the design to split the concept into small chunks. There is a clear focus on how the number of original phenotypes and recombinants can be used to determine linkage and suggest how the loci of the two genes compare. Important links to other topics such as crossing over in meiosis are made to enable students to understand how the random formation of the chiasma determines whether new phenotypes will be seen in the offspring or not. Linkage is an important cause of variation and the difference between observed and expected results and this is emphasised on a number of occasions. The main task of the lesson acts as an understanding check where students are challenged to analyse a set of results involving the inheritance of the ABO blood group gene and the nail-patella syndrome gene to determine whether they have loci on the same chromosome and if so, how close their loci would appear to be.
This lesson has been written to tie in with the other lessons from module 6.1.2 (Patterns of Inheritance)
A concise lesson presentation (19 slides) and associated worksheet (newspaper articles) that introduces students to the process of homeostasis in the human body and the three main factors (water potential, blood glucose, temperature) that are controlled by this system. The lesson begins by getting the students to work out a code to give them an exemplary definition for homeostasis. A newspaper article is used to get the students to recognise the three factors that are controlled. A quick competition is used to show the students the main parts of any homeostatic control system.
This lesson is designed for GCSE students but could be used with both KS3 and A-level as a quick recap
This fully-resourced lesson explores the relationship between the structure of arteries, arterioles and veins and their respective functions. The engaging and detailed PowerPoint and accompanying resources have been designed to cover the 6th part of point 3.4.1 of the AQA A-level Biology specification which states that students should be able to describe the structure of these blood vessels in relation to their function.
This lesson has been written to build on any prior knowledge from GCSE or earlier in this topic to enable students to fully understand why a particular type of blood vessel has particular features. Students will be able to make the connection between the narrow lumen and elastic tissue in the walls of arteries and the need to maintain the high pressure of the blood. A quick version of the GUESS WHO game is used to introduce smooth muscle and collagen in the tunica media and externa and again the reason for their presence is explored and explained. Moving forwards, the importance of the arterioles as a transition between the artery and capillary is discussed and students will see how the smooth muscle in the walls of this blood vessel allows for the redistribution of blood during exercise. The final part of the lesson considers the structure of the veins and students are challenged to explain how the differences to those observed in arteries is due to the lower blood pressure found in these vessels.
It is estimated that it will take about 2 hours of allocated A-level Biology teaching time to cover the detail included in this lesson
This is a highly detailed, engaging and fully-resourced lesson that covers the detail of the 2nd part of specification point 5.1.2 (b) of the OCR A-level Biology A specification which states that students should be able to demonstrate and apply an understanding of the functions of the mammalian liver. The liver performs a large number of metabolic functions and the majority of them are covered within this lesson. However, the lesson focuses on the following three roles:
The formation of urea by deamination and the ornithine cycle
The storage of glycogen
The detoxification of alcohol
As well as covering the detail of the current topic, numerous opportunities are taken to make links to other topics and to check on the students prior knowledge. Previous knowledge check questions on biological molecules, coenzymes and the structure of the liver are found dispersed within the understanding checks and quick quiz competitions are used to introduce key terms and values in a fun and a memorable way.
This lesson has been designed for students on the OCR A-level Biology A course and ties in well with the other uploaded lessons on module 5.1.2 about the structure and function of the kidney
This is a highly-detailed and fully-resourced lesson which covers the detail of specification point 14.1 (g) of the CIE International A-level Biology specification which states that students should be able to describe the roles of the hypothalamus, posterior pituitary, ADH and collecting ducts in osmoregulation. Students learnt about the principles of homeostasis and negative feedback in an earlier lesson, 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 CIE International A-level Biology course and ties in closely with the other uploaded lessons on the structure of the kidney, ultrafiltration and selective reabsorption
This lesson has been designed to cover the content as detailed in points 2.1, 2.2 and 2.3 (Mitosis as part of the cell cycle) of the Edexcel GCSE Biology & Combined Science specifications. Consisting of a detailed and engaging PowerPoint (44 slides) and an accompanying worksheet, the range of activities will motivate the students whilst ensuring that the content is covered in detail. Students will learn how interphase, the 4 phases of mitosis and cytokinesis result in the production of genetically identical diploid daughter cells. Time is taken to go through each of the three stages of the cell cycle in detail so students can recognise how the key events of each stage allow this important form of “copying” cell division to occur. 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 The Big REVEAL 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 Edexcel GCSE Biology or Combined Science specifications but can be used with older students who need to know the key details of the cell cycle for their A level course before taking it to greater depths
This fully-resourced lesson explores how genetic and environmental factors cause phenotypic variation. The engaging PowerPoint and accompanying worksheets have been designed to cover the first part of point 7.3 of the AQA A-level Biology specification which states that students should be able to describe how mutations and meiosis both contribute to genetic variation
Students are challenged at the start of the lesson to recognise the terms phenotype and species from their definitions in order to begin a discussion on the causes of the phenotypic variation within a species. Moving forwards, students will recall that mutations are the primary source of genetic variation and time is taken to look at the effect of gene and chromosome mutations. Just like the majority of parts of this specification point, gene mutations were covered earlier in topic 4 so these tasks act as a prior knowledge check as students have to recognise the different types of gene mutations and explain their effects on the primary structure with reference to the genetic code. These prior knowledge checks are found throughout the lesson and challenge the knowledge of other topics that include photosynthesis, meiosis and inorganic ions. The karyotype of an individual who has Down syndrome is used to introduce chromosome mutations and students will be introduced to the different types, with a focus on non-disjunction. The key events of meiosis that produce variation (crossing over and independent assortment) are explored and students will be given a mathematical formula to use to calculate the number of chromosome combinations in gametes and in the resulting zygote. The final part of the lesson looks at chlorosis and how an environmental factor can prevent the express of a gene.
Every one of the lessons included in this bundle is detailed, engaging and fully-resourced, and has been written to cover the content as detailed in topic 4 of the AQA A-level Biology specification. The wide range of activities will maintain engagement whilst supporting the explanations of the content to allow the students to build a deep understanding of genetic information, variation and relationships between organisms.

This lesson describes and explains how production is affected by a range of farming practices designed to increase the efficiency of energy transfer. The PowerPoint and accompanying resources are part of the third lesson in a series of 3 which have been designed to cover the detail included in specification point 5.3 of the AQA A-level Biology specification.
Over the course of the lesson, a range of tasks which include exam-style questions with displayed mark schemes, guided discussion periods and quick quiz competitions will introduce and consider the following farming practices:
raising herbivores to reduce the number of trophic levels in a food chain
intensely rearing animals to reduce respiratory losses in human food chains
the use of fungicides, insecticides and herbicides
the addition of artificial fertilisers
The ethical issues raised by these practices are also considered and alternative methods discussed such as the addition of natural predators and the use of organic fertilisers like manure
As this is the last lesson in topic 5.3, it has been specifically planned to challenge the students on their knowledge of the previous two lessons and this includes a series of questions linking farming practice to the formula to calculate net production
This is a fully-resourced revision lesson that uses a combination of exam questions, understanding checks, quick tasks and quiz competitions to enable students to assess their understanding of the content found within Topic 6 (Immunity, infection and forensics) of the Pearson Edexcel A-level Biology A specification.
The sub-topics and specification points that are tested within the lesson include:
Know how DNA profiling is used for identification and determining genetic relationships

Understand how HIV infects human cells, causing a sequence of symptoms that may result in death
Understand the non-specific responses of the body to infection
Understand the roles of antigens and antibodies in the body’s immune response
Understand the differences between the roles of B cells and T cells
Understand how one gene can give rise to more than one protein through post-transcriptional changes
Understand the difference between bacteriostatic and bactericidal antibiotics
Students will be engaged through the numerous quiz rounds such as “FROM NUMBERS 2 LETTERS” and “Make sure you are very SPECIFIC” whilst crucially being able to recognise those areas which require their further attention during general revision or during the lead up to the actual A-level terminal exams
This is a detailed, engaging and fully-resourced REVISION LESSON which allows students of all abilities to assess their understanding of the content in topic 6 (Nucleic acids and protein synthesis) of the CIE International A-level Biology specification. Considerable time has been taken to design the lesson to include a wide range of activities to motivate the students whilst they evaluate their knowledge of DNA, RNA and the roles of these nucleic acids in DNA replication and protein synthesis. Most of the tasks have been differentiated so that students of differing abilities can access the work and move forward as a result of the tasks at hand.
This lesson has been planned to cover as much of the specification as possible but the following sub-topics have received particular attention:
The structure of DNA
Phosphorylated nucleotides
DNA replication
Transcription and translation
Gene mutations and their affect on the primary structure of a polypeptide
The structure of RNA
In addition to a focus on the current topic, links are made throughout the lesson to other topics such as the journey of an extracellular protein following translation and the cell cycle.

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.
This bundle contains 17 fully-resourced and detailed lessons that have been designed to cover the content of topic 6 of the AQA A-level Biology specification which concerns the responses of organisms to stimuli. The wide range of activities included in each lesson will engage the students whilst the detailed content is covered and the understanding and prior knowledge checks allow them to assess their progress on the current topic as well as challenging them to make links to other related topics. Most of the tasks are differentiated to allow differing abilities to access the work and be challenged.

The mathematic elements of the Combined Science specification are challenged throughout the resource.
Due to the size of this resource, it is likely that it’ll be used over the course of a number of lessons and it is suitable for use as an end of topic revision aid, in the lead up to the mocks or in the lead up to the actual GCSE exams.
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 detailed lesson describes the structure of the mammalian kidney and the nephron. The PowerPoint and accompanying resource have been designed to cover specification point [c] in topic 7 of A2 unit 3 of the WJEC A-level Biology specification. The lesson has been planned to tie in with the other lessons in topic 7 on reabsorption in the proximal tubule and the role of the ADH in the homeostatic balance of blood water potential and a common theme runs throughout to allow students to build their knowledge gradually and develop a deep understanding of this organ.
Students will come to recognise the renal cortex and renal medulla as the two regions of the kidney and learn the parts of the nephron which are found in each of these regions. Time is taken to look at the vascular supply of this organ and specifically to explain how the renal artery divides into the afferent arterioles which carry blood towards the glomerulus and the efferent arterioles which carry the blood away. The main task of the lesson challenges the students to relate structure to function. Having been introduced to the names of each of the parts of the nephron, they have to use the details of the structures found at these parts to match the function. For example, they have to make the connection between the microvilli in the PCT as a sign that this part is involved in selective reabsorption.
Please note that there are no electron micrographs of the kidney in this lesson.
This lesson describes how to calculate the mean and standard deviation of collected data and describes how these values may be interpreted. The PowerPoint and accompanying worksheets are part of the second lesson in a series of 2 lessons which have been designed to cover point 4.7 (Investigating diversity) of the AQA A-level Biology specification. It is important to note that the students will not be required to calculate the standard deviation in written papers but that they do need to understand how these values are obtained and what they could indicate.
The lesson begins with an introduction of the standard deviation as a measure of the spread around the mean. The students will learn that interpreting the data is a critical requirement of this A-level course and this initial portion of the lesson considers how the spread of the data around the mean can lead to differing suggestions about reliability. A step by step guide walks the students through each stage of the calculation of the standard deviation, which includes the calculation of the mean, and they will complete a worked example with the class. A quick quiz round introduces the values of 68 and 95 in a fun way to encourage the students to remember that if the focus of the data shows a normal distribution, 68% of the observations are within +/- one standard deviation and 95% are within 2 standard deviations. The final task challenges the students to apply their knowledge to data about the birth weights of humans at a UK hospital on one day in 2020.
