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 detailed and fully-resourced lesson describes the relationship between the structure and function of the polysaccharides: glycogen, starch and cellulose. The engaging PowerPoint and accompanying resources have been designed to cover the third part of point 1.2 of the AQA A-level Biology specification and clear links are also made to the previous lessons in this topic where the monosaccharides and disaccharides were introduced.
By the end of this lesson, students should understand how key structural features like the 1 - 4 and 1 - 6 glycosidic bonds and the hydrogen bonds dictate whether the polysaccharide chain is branched or unbranched and also whether it spirals or not. Following the description of the structure of glycogen, students are challenged to design an exam question in the form of a comparison table so that it can be completed as the lesson progresses once they learn more about starch and cellulose. This includes a split in the starch section of the table so that the differing structures and properties of amylose and amylopectin can be considered. In the final part of the lesson, time is taken to focus on the formation of cellulose microfibrils and macrofibrils to explain how plant cells have the additional strength needed to support the whole plant.
Due to the detail included in this lesson, it is estimated that it will take in excess of 2 hours of allocated teaching time to complete
This detailed lesson describes the structure of a nucleotide and a phosphorylated nucleotide and explains how polynucleotides are synthesised and broken down. The engaging PowerPoint has been designed to cover points [a], [b] and [c] of module 2.1.3 as detailed in the OCR A-level Biology A specification and links are made throughout to earlier topics such as biological molecules.
Students were introduced to the term monomer and nucleotide in the previous module, so the start of the lesson challenges them to recognise this latter term when only the letters U, C and T are shown. This has been designed to initiate conversations about why only these letters were used so that the nitrogenous bases can be discussed later in greater detail. Moving forwards, students will learn that a nucleotide is the monomer to a polynucleotide and that deoxyribonucleic acid (DNA) and ribonucleic acid (RNA) are two examples of this type of polymer. The main part of the lesson has been filled with various tasks that explore the structural similarities and structural differences between DNA and RNA. This begins by describing the structure of a nucleotide as a phosphate group, a pentose sugar and a nitrogenous base. Time is taken to consider the details of each of these three components which includes the role of the phosphate group in the formation of a phosphodiester bond between adjacent nucleotides on the strand. At this point students are challenged on their understanding of condensation reactions and have to identify how the hydroxyl group associated with carbon 3 is involved along with the hydroxyl group of the phosphoric acid molecule. A number of quiz rounds are used during this lesson, as a way to introduce key terms in a fun and memorable way. One of these rounds introduces adenine and guanine as the purine bases and thymine, cytosine and uracil as the pyrimidine bases and the students are shown that their differing ring structures can be used to distinguish between them. The remainder of the lesson focuses on ADP and ATP as phosphorylated nucleotides and links are made to the hydrolysis of this molecule for energy driven reactions in cells such as active transport
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 lesson covers a large number of the key topics from the AQA GCSE Combined Physics course in the final weeks before the GCSE examinations.

This resource is likely to take 4 or more lessons to cover all of the content.
This engaging revision lesson challenges students on their understanding of the homeostatic control system that regulates blood glucose concentration. The PowerPoint and accompanying resources have been designed to check on the understanding of the details in specification point 5.3.2 of the AQA biology and combined science specifications.
A common mistake in this topic is that students confuse glycogen with glucagon and use them incorrectly so time is spent to ensure that students recognise the difference between the complex carbohydrate and the hormone.
In addition to challenging the students on their knowledge of this control system, the following linked topics are also challenged:
key biological terms (beginning with G)
the digestive system
structures in a control system
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 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.
This fully-resourced lesson uses the lac operon as an example to describe how gene expression is regulated and controls cell processes and structures. The detailed PowerPoint and accompanying resources have been designed to cover the details of specification point 3.12 of the Pearson Edexcel A-level Biology A course.
This is one of the more difficult concepts in this A-level course and therefore key points are reiterated throughout this lesson to increase the likelihood of student understanding and to support them when trying to make links to actual biological examples in living organisms. There is a clear connection to transcription and translation as covered in topic 2, so the lesson begins by reminding students that in addition to the structural gene in a transcription unit, there is the promotor region where RNA polymerase binds. Students are introduced to the idea of transcription factors and will understand how these molecules can activate or repress transcription by enabling or preventing the binding of the enzyme. At this point, students are challenged on their current understanding with a series of questions about DELLA proteins so they can see how these molecules prevent the binding of RNA polymerase. The main section of the lesson focuses on the lac operon. Students will be able to visualise the different structures that are found in this unit of DNA and time is taken to go through the individual functions. A step by step guide is used to walk students through the sequence of events that occur when lactose is absent and when it is present before they are challenged to apply their understanding to an exam question. The final section of the lesson looks at one further example with oestrogen and the ER receptor.
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 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 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 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 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 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.
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 written to act as a revision tool for students at the completion of topic P1 of the CIE IGCSE Combined Science specification or in the lead up to mock or terminal exams. This motion topic is extensive and the engaging PowerPoint and accompanying resources have been designed to include a wide range of activities that will allow the students to assess their understanding of the core and supplement sections and to recognise any areas which need further attention. This specification is fairly heavy in mathematical content and so a lot of opportunities are presented for a range of skills to be tested and the PowerPoint guides students through the application of these requirements such as rearranging the formula and converting between units.
The following specification points have received a particular focus in this lesson:
Calculate average speed using total distance and total time
Plot and interpret a speed-time graph
Recognise different motions on a speed time graph and relate this to the resultant force
Calculate acceleration and distance travelled from a speed-time graph
Distinguish between mass and weight
Recall and use the equation W = mg to calculate the weight
Recall and use the equation to calculate density
Interpret extension-load graphs and calculate the spring constant
Recognise the significance of the term, “limit of proportionality”
Recall and use the equation to calculate pressure
A number of quick quiz rounds, such as FILL THE VOID and THE BIG REVEAL, are used to maintain engagement and motivation and to challenge the students on their recall of important points.
It is estimated that it will take in excess of 2 hours of IGCSE teaching time to cover the detail included in this lesson
This detailed and engaging lesson has been written to challenge the students on their recall and application of the 22 equations which they have to know for the AQA GCSE Physics exams. The lesson is designed to not only check that they know these equations but also on their ability to rearrange formulae when required and to convert between units. The main task of the lesson consists of 13 exam-style questions which challenge 12 of these recall equations and then an engaging quiz competition and class discussions are used to identify the other 10. Students are guided throughout the lesson in the use of the mathematical skills and are shown examples to aid their progress.
This lesson has been designed to tie in with the other 12 uploaded revision lessons which cover the content of the topics on the Edexcel GCSE Physics specification
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
