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.
This resource has been designed to motivate students whilst they evaluate their understanding of the content in modules 1, 2, 3 and 5 of the OCR A-level Biology A specification which can be assessed in PAPER 1 (Biological processes). The resource includes a detailed and engaging Powerpoint (149 slides) and is fully-resourced with differentiated worksheets that challenge the students on a wide range of topics.
The resource has been written to include different types of activities such as exam questions with explained answers, understanding checks and quiz competitions. The aim was to cover as much of the specification content as possible but the following topics have been given particular attention:
Monosaccharides, disaccharides and polysaccharides
Glycogen and starch as stores and providers of energy
The homeostatic control of blood glucose concentration
Osmoregulation
Lipids
Ultrafiltration and selective reabsorption
Diabetes mellitus
Voluntary and involuntary muscle
The autonomic control of heart rate
The organisation of the nervous system
The gross structure of the human heart
Haemoglobin and the Bohr shift
Bonding
The ultrastructure of plant cells
Cyclic vs non-cyclic photophosphorylation
Oxidative phosphorylation
Anaerobic respiration in eukaryotes
Helpful hints and tips are given throughout the resource to help students to structure their answers. This resource can be used in the lead up to the actual Paper 1 exam or earlier in the course when a particular area of modules 1, 2, 3 or 5 is being studied.
If you are happy with this resource, why not look at the one which has been designed for Paper 2 (Biological diversity)?
These 12 lessons cover points 15.1 (1, 3, 4, 5, 6, 7, 9, 10, 11 & 12) and 15.2 (1, 2 & 3) from topic 15 of CIE A-level biology specification (for assessment in 2025 - 27). This topic is titled control and coordination and concerns comparisons between the endocrine and nervous system in mammals, and then the key structure of the nervous system before looking at this control in plants.
Each lesson has been extensively planned and contains a wide range of engaging activities and tasks, interspersed with current and prior knowledge checks.

This detailed lesson describes the absorption of water, the movement through the root and the role of the endodermis. Both the PowerPoint and accompanying resource have been designed to cover specification points (j, k & l) in topic 3 of AS unit 2 of the WJEC A-level Biology specification and includes descriptions of the apoplast, symplast and vacuolar pathways and the Casparian strip.
The lesson begins by looking at the specialised features of the root hair cell so that students can understand how these epidermal cells absorb water and mineral ions from the soil. Moving forwards, students are introduced to key terminology such as epidermis and root cortex before time is taken to look at the different pathways that water and minerals use to transverse across the cortex. Discussion points are included throughout the lesson to encourage the students to think about each topic in depth and challenges them to think about important questions such as why the apoplast pathway is needed for the water carrying the ions. The main part of the lesson focuses on the role of the endodermis in the transport of the water and ions into the xylem. Students will be introduced to the Casparian strip and will learn how this layer of cells blocks the apoplast pathway. A step by step method using class questions and considered answers is used to guide them through the different steps and to support them when writing the detailed description.
This lesson has been written to tie in with the next lesson on the pathways and mechanisms by which water and mineral ions are transported to the leaves.
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 has been designed to cover the content of specification point 5.2.2 (The brain) as found in topic 5 of the AQA GCSE Biology specification. This resource contains an engaging PowerPoint (33 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 cancer.
The following content is covered in this lesson:
The functions of the cerebral cortex, medulla and cerebellum
Identification of the regions of the brain on an external and internal diagram
The early use of stroke victims to identify functions
The key details of the MRI scanning technique
The difficulties of diagnosing and treating brain disorders and disease
As stated at the top, this lesson has been designed for GCSE-aged students who are studying the AQA GCSE Biology course, but it can be used with A-level students who need to go back over the key points before looking at the functionality of the regions in more detail
A detailed lesson presentation (37 slides) and associated worksheets that looks at the different pieces of evidence that scientists use to support evolution and discusses how these support the theory. The lesson begins by challenging students to decide which piece of evidence is the key piece in supporting evolution (fossils). Students will then have to arrange a number of statements to describe how a fossil is formed. Students are introduced to the fossil record and questions are used to check that they understand where the oldest fossils would be found. Moving forwards, students are given three pieces of evidence that would be observed in the fossil record and they are challenged to explain how each of these supports the theory of evolution. Quick competitions are then used to get the students to see some extinct organisms in the Dodo and Woolly Mammoth and again they are questioned on how extinct animals support the theory of evolution. Further evidence in rapid changes in species and molecular comparison is discussed. There are regular progress checks throughout the lesson so that students can assess their understanding and there is a set homework included.
The AQA specification states that a minimum of 10% of the marks across the 3 assessment papers will require the use of mathematical skills. This revision lesson has been designed to include a wide range of activities that challenge the students on these exact skills because success in the maths in biology questions can prove the difference between one grade and the next!
Step-by-step guides are used to walk students through the application of a number of the formulae and then exam-style questions with clear mark schemes (which are included in the PowerPoint) will allow them to assess their progress. Other activities include differentiated tasks, group discussions and quick quiz competitions such as “FROM NUMBERS 2 LETTERS” and “YOU DO THE MATH”.
The lesson has been written to cover as much of the mathematical requirements section of the specification as possible but the following have been given particular attention:
Hardy-Weinberg equation
Chi-squared test
Calculating size
Converting between quantitative units
Standard deviation
Estimating populations of sessile and motile species
Percentages and percentage change
Cardiac output
Geometry
Due to the detail and extensiveness of this lesson, it is estimated that it will take in excess of 2/3 hours of A-level teaching time to work through the activities and it can be used throughout the duration of the course
This bundle contains 20 PowerPoint lessons, and all are highly-detailed and are fully-resourced with differentiated worksheets. Intricate planning means that the wide range of activities included in these lessons will engage and motivate the students, check on their current understanding and their ability to make links to previously covered topics and most importantly will deepen their understanding of the following specification points in topic 2 (Cells) of the AQA A-level Biology specification:
Structure and function of the organelles in eukaryotic cells

An engaging lesson presentation (33 slides) and associated worksheets that introduces students to classification using the taxonomic levels and teaches them how to name species using the binomial naming system. The students are told about the domain system, as developed by Carl Woese, but then the lesson focuses on showing them the seven levels that come after this. Students are challenged to understand how the levels differ from each other in terms of sharing characteristics. Time is taken to focus on the five kingdoms and links are made to other topics such as prokaryotic cells to test their previous knowledge. Moving forwards, students are shown how the genus and species are used in the binomial naming system before being given lots of opportunities to assess their understanding through questions.
This lesson has been written for GCSE students but is suitable for all age ranges
This highly detailed, fully-resourced lesson has been designed to cover the content of specification point 5.1.4 (d) of the OCR A-level Biology A specification which states that students should be able to demonstrate and apply an understanding of the regulation of blood glucose concentration. There is focus on the negative feedback mechanisms that release insulin or glucagon and the role of the liver. It challenges the students recall of the control of insulin release from the beta cells which was taught in an earlier lesson.
A wide range of activities will maintain motivation and engagement whilst the content is covered in detail to enable the students to explain how the receptors in the pancreas detect the concentration change and how the hormones attaching to receptor sites on the liver triggers a series of events in this effector organ. This is a topic which has a huge amount of difficult terminology so time is taken to look at all of the key words, especially those which begin with the letter G so students are able to use them accurately in the correct context. The action of adrenaline is also considered and linked to the breakdown of glycogen to glucose during glycogenolysis.
This lesson has been written for students studying on the OCR A-level Biology A course and ties in with the lesson on the differences between type I and II diabetes mellitus as well as the human endocrine system
This bundle contains 17 fully-resourced and detailed lessons that have been designed to cover the content of topic 7 of the AQA A-level Biology specification which concerns genetics, populations, evolution and ecosystems. The wide range of activities included in each lesson will engage the students whilst the detailed content is covered and the understanding and previous 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.

This detailed lesson introduces the 3 main principles of the cell theory and describes how cells are organised into tissues, organs and organ systems. The engaging PowerPoint and accompanying resources have been designed to cover points 2.1 (i) & (ii) of the Edexcel A-level Biology B specification.
The cell theory is introduced at the start of the lesson and the 1st principle is immediately discussed to ensure that students are aware that all living organisms are made of cells. This principle is discussed with relation to viruses to enable students to understand that the lack of cell structure in a virus is one of the reasons that they are not considered to be living. The second principle states that the cell is the basic unit of structure and organisation and this leads into the main part of the lesson where specialised cells and their groupings into tissues are considered. Students are challenged to compare an amoeba against a human to get them to focus on the difference in the SA/V ratio. This acts as an introduction into the process of differentiation and a recognition of its importance 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 third principle states that cells arise from pre-existing cells and this will be demonstrated later in topic 2 with mitosis and meiosis.
This concise lesson acts as an introduction to topic 5.3, Energy and Ecosystems, and describes how plant biomass is formed, measured and estimated. The engaging PowerPoint is the 1st in a series of 3 lessons which have been designed to cover the detailed content of topic 5.3 of the AQA A-level Biology specification.
A quiz round called REVERSE Biology Bingo runs throughout the lesson and challenges students to recognise the following key terms from descriptions called out by the bingo caller:
community
ecosystem
abiotic factor
photosynthesis
respiratory substrate
biomass
calorimetry
The ultimate aim of this quiz format is to support the students to understand that any sugars produced by photosynthesis that are not used as respiratory substrates are used to form biological molecules that form the biomass of a plant and that this can be estimated using calorimetry. Due to the clear link to photosynthesis, a series of prior knowledge checks are used to challenge the students on their knowledge of this cellular reaction but as this is the first lesson in the topic, the final section of the lesson looks forwards and introduces the chemical energy store in the plant biomass as NPP and students will also meet GPP and R so they are partially prepared for the next lesson.
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.
A fully resourced lesson which includes an informative lesson presentation (34 slides) and differentiated worksheets that show students how to convert between units so they are confident to carry out these conversions when required in Science questions. The conversions which are regularly seen at GCSE are covered as well as some more obscure ones which students have to be aware of. A number of quiz competitions are used throughout the lesson to maintain motivation and to allow the students to check their progress in an engaging way
This lesson has been designed for GCSE students but is suitable for KS3
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
A series of 5 exam questions that challenge students to work out the actual size of a section as seen under a microscope or the magnification. These questions will test their ability to convert between measurements and give answers in micrometers. These questions are suitable for GCSE and A-level students
