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 is a fully-resourced lesson which uses exam-style questions, engaging quiz competitions, quick tasks and discussion points to challenge students on their understanding of the content of topics P1 & P8 - P15, that will assessed on PAPER 6. It has been specifically designed for students on the Edexcel GCSE Combined Science course who will be taking the FOUNDATION TIER examinations but is also suitable for students taking the higher tier who need to ensure that the fundamentals are known and understood.
The lesson has been written to cover as many specification points as possible but the following sub-topics have been given particular attention:
The 13 recall and apply equations tested in PAPER 6
Electrical components and symbols
Setting up an ammeter and voltmeter in a circuit
Current and potential difference in a series circuit
The change in resistance in a LDR, diode, thermistor and filament bulb
Mains domestic supply in the UK
Plugs and fuses as safety devices
Contact and non-contact forces
Attraction and repulsion in magnets
Magnetic fields
Changes of state as physical changes
The extension of a spring
In order to maintain challenge whilst ensuring that all abilities can access the questions, the majority of the tasks have been differentiated and students can ask for extra support when they are unable to begin a question. A revision quiz, consisting of 10 rounds, runs over the course of the lesson and a score sheet is included with the resources to maintain motivation and engagement.
Due to the extensiveness of this revision lesson, it is estimated that it will take in excess of 3 teaching hours to complete the tasks and therefore this can be used at different points throughout the course as well as acting as a final revision before the PAPER 6 exam.
This detailed and engaging lesson has been written to challenge the students on their recall and application of the 30 equations which they have to know for the CIE IGCSE 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 15 exam-style questions which challenge 17 of these recall equations and then an engaging quiz competition and class discussions are used to identify the other 13. Students are guided throughout the lesson in the use of the mathematical skills and are shown examples to aid their progress.
The detail of this lesson means that it can be used at numerous times throughout the duration of the IGCSE course to check on their progress with the equations.
This lesson has been designed to tie in with the other 5 uploaded revision lessons which cover the content of the 5 topics on the specification
This is a fully-resourced revision lesson that uses a combination of exam questions, understanding checks, quick tasks and quiz competitions to help the students to assess their understanding of the sub-topics found within Topic C4 (Extracting metals and equilibria) of the Edexcel GCSE Combined Science specification.
The sub-topics and specification points that are tested within the lesson include:
Redox reactions
The extraction of metals
Extracting metals by heating with carbon and by electrolysis
Life cycle assessment
Reversible reactions
The formation of ammonia as a reversible reaction
The conditions for the Haber process
Predicting how the position of a dynamic equilibrium is affected by changes in pressure and temperature
Students will be engaged through the numerous quiz rounds whilst crucially being able to recognise those areas which require their further attention during general revision or during the lead up to the actual assessment
This lesson describes the general structure of the 20 amino acids found in proteins and makes clear links to related topics such as genes. The PowerPoint has been designed to cover specification point 2.1.2 (k) of the OCR A-level Biology A course and provides a clear introduction to the following lesson on the formation of dipeptides and polypeptides.
The lesson begins with a prior knowledge check, where the students have to use the 1st letters of 4 answers to uncover a key term. This 4-letter key term is gene and the lesson begins with this word because it is important for students to understand that these sequences of bases on DNA determine the specific sequence of amino acids in a polypeptide. Moving forwards, students are given discussion time to work out that there are 64 different DNA triplets and will learn that these encode for the 20 amino acids that are common to all organisms. The main task of the lesson is an observational one, where students are given time to study the displayed formula of 4 amino acids. They are not allowed to draw anything during this time but will be challenged with 3 multiple choice questions at the end. This task has been designed to allow the students to visualise how the 20 amino acids share common features in an amine and an acid group. A quick quiz round introduces the R group and time is taken to explain how the structure of this side chain is the only structural difference. Students will be introduced to the existence of hydrophobic, hydrophilic, acidic and basic R groups so that they are able to apply this knowledge in future lessons where structure and shape is considered. Some time is also given to look at cysteine in greater detail due to the presence of sulfur atoms and once again a link is made to disulfide bridges for upcoming lessons. The lesson concludes with one more quiz round called LINK TO THE FUTURE where the students will see the roles played by amino acids in the later part of the course such as translation and in the formation of dipeptides.
This engaging lesson describes the relationship between the structure and functions of a phopholipid, focusing on the role performed in membranes. The PowerPoint has been designed to cover specification point 2.2 (g) of the CIE International A-level Biology specification and includes constant references to the previous lesson on the structure and function of triglycerides.
The role of a phospholipid in a cell membrane provides the backbone to the whole lesson. A quick quiz round called FAMILY AFFAIR challenges the students to use their knowledge of the structure of a triglyceride to identify the shared features in a phospholipid. This then allows the differences to be introduced, such as the presence of a phosphate group in place of the third fatty acid. Moving forwards, the students will learn that the two fatty acid tails are hydrophobic whilst the phosphate head is hydrophilic which leads into a key discussion point where the class has to consider how it is possible for the phospholipids to be arranged when both the inside and outside of a cell is an aqueous solution. The outcome of the discussion is the introduction of the phospholipid bilayer which is critical for the lesson in topic 4 on the fluid mosaic model. The final part of the lesson describes how proteins found floating in the cell membrane allow both facilitated diffusion and active transport to occur and this also helps to begin the preparations for the upcoming lessons.
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 fully-resourced lesson describes the differences between bacteriostatic and bactericidal antibiotics. The engaging PowerPoint and accompanying resources have been designed to cover point 6.13 of the Edexcel International A-level Biology specification but also makes continual links to earlier lessons in topic 6 as well as related topics from the previous year such as protein synthesis from topic 2
The lesson begins by challenging the students to use their knowledge of the previous topic 6 lessons to identify the suffixes cidal and static. Students will learn that when the prefix is added, these form the full names of two types of antibiotics. Their understanding of terminology is tested further as they have to recognise that Polymyxin B is an example of a bactericidal antibiotic as its actions would result in the death of the bacterial cell. Tetracycline is used as the example of a bacteriostatic antibiotic and students will discover that its prevention of the binding of tRNA that inhibits protein synthesis and this reduction and stopping of growth and reproduction is synonymous with these drugs. Students are challenged on their knowledge of translation and will also be given time for a class discussion to understand that these antibiotics encourage the body’s immune system to overcome the pathogen in natural, active immunity.
The final part of the lesson uses a quick quiz competition and a series of exam-style questions to ensure that students can recognise the different antibiotics from descriptions.
This engaging and detailed lesson looks at the roles of the Link reaction and the Krebs cycle as the stages of aerobic respiration which occur in the mitochondrial matrix. Both the PowerPoint and the accompanying resource have been designed to cover point 7.5 of the Pearson Edexcel A-level Biology A (Salters Nuffield) specification.
The lesson begins with a challenge, where the students have to recall the details of glycolysis in order to form the word matrix. This introduces the key point that these two stages occur in this part of the mitochondria and time is taken to explain why the reactions occur in the matrix as opposed to the cytoplasm like glycolysis. Moving forwards, the Link reaction is covered in 5 detailed bullet points and students have to add the key information to these points using their prior knowledge as well as knowledge provided in terms of NAD. The students will recognise that this reaction occurs twice per molecule of glucose and a quick quiz competition is used to test their understanding of the numbers of the different products of this stage. This is just one of the range of methods that are used to check understanding and all answers are explained to allow students to assess their progress. The rest of the lesson focuses on the Krebs cycle. In line with the detail of the specification, students will understand how decarboxylation and dehydrogenation reactions result in the regeneration of the 4C compound.
It is estimated that it will take about 2 hours of A-level teaching time to cover the detail of the lesson and therefore the detail of the specification point 7.5
This clear and concise lesson explores the roles of the coenzymes NAD, FAD and coenzyme A in cellular respiration as detailed in point 12.1 (d) of the CIE International A-level Biology specification.
As this specification point comes before the specification points concerning the details of the stages of respiration, this lesson has been designed to introduce the key details whilst focusing on their roles. Students will understand that NAD and FAD are reduced upon accepting hydrogen atoms and then carry these protons and electrons to the cristae where they are used in the production of ATP. In addition, they will learn that coenzyme A is used in the link reaction and helps to deliver the acetyl group to the Krebs cycle
A concise lesson presentation (26 slides) that looks at how sexual reproduction leads to variation and considers the advantages and disadvantages of this form of reproduction. The lesson begins by getting the students to recognise that sexual reproduction needs two parents and therefore two gametes. Time is taken to ensure that students understand that these gametes are produced by meiosis and therefore contain the haploid number of chromosomes. Key terminology like haploid and zygote are used throughout the lesson.
This lesson is suitable for both KS3 and GCSE students
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 revision resource has been designed to include a range of activities that will engage the students whilst they assess their understanding of the content of topic B8 (Gas exchange and respiration) of the CIE IGCSE Combined Science specification for examination in June and November 2020 and 2021. Exam questions, quick tasks and quiz competitions such as “The BIG REVEAL” will challenge the students on their recall of the content as well as their ability to apply this knowledge.
The lesson was written to cover as much of the content as possible, but the following topics have received particular attention:
The role of cilia, goblet cells and mucus in the trachea and bronchi
The effects of the chemicals in tobacco smoke on gas exchange
Efficient gas exchange at the alveoli
The composition of inhaled and exhaled air
Aerobic respiration as the chemical reaction that releases energy
The uses of energy in the human body
This resource contains an engaging PowerPoint (54 slides) and associated worksheets and is ideal for use at the end of this topic or in the lead up to mocks or the actual terminal exams
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 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 lesson describes how molecular evidence can be used to reveal similarities between closely-related organisms. The PowerPoint and accompanying resources have been primarily designed to cover point 17.3 (b) of the CIE A-level Biology specification and focus on the comparison of protein structure and mitochondrial DNA but can also be used as a revision of related topics that include protein synthesis and gene mutations.
The lesson begins with the introduction of convergent evolution, a process where organisms independently evolve to have similar features due to theeir habitation of similar environments. This allows the importance of molecular evidence to be considered to ensure that organisms which are closely related (in terms of evolution) are recognised. The comparison of the primary structure of a protein involved in respiration (cytochrome c) is used to demonstrate how protein sequence data can be useful. At this point, a series of exam-style questions are used to challenge the students on their knowledge of protein synthesis and gene mutations from topics 6 and 16. The remainder of the lesson considers the use of mitochondrial DNA and a study of the mtDNA genomes of 51 gibbons demonstrates how this can provide evidence of relationships, even in organisms that show high taxonomic diversity like these lesser apes.
This detailed lesson outlines the characteristics features of the kingdoms Protoctista, Fungi, Plantae and Animalia. The engaging PowerPoint and accompanying resources have been designed to cover point 18.2 [c] of the CIE International A-level Biology specification which states that students should be able to describe the features of these four eukaryotic kingdoms.
This lesson begins with a knowledge recall as students have to recognise that prior to 1990, kingdom was the highest taxa in the classification hierarchy. Moving forwards, they will recall the names of the five kingdoms and immediately be challenged to split them so that the prokaryotae kingdom is left on its own. The features of this kingdom are given so that the lesson can focus on the four eukaryotic kingdoms. Students are constantly challenged on their understanding of the current topic as well as that of earlier topics, as demonstrated by a differentiated task about the structure and function of cellulose which was covered in topic 2. This task is found in the section of the lesson where the main constituent of the wall can be used to distinguish between plantae, fungi and prokaryotae. Quick quiz competitions, such as SAY WHAT YOU SEE are used to introduce key terms in a fun and memorable way. The final part of the lesson looks at the protoctista kingdom and students will come to understand how these organisms tend to share a lot of animal or plant-like features.
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 fully-resourced lesson describes the inheritance of genes that are carried on the X chromosome and includes a particular focus on haemophilia in humans. The detailed PowerPoint and associated differentiated resources have been designed to cover specification point 8.2 (v) as detailed in the Edexcel A-level Biology B specification.
Key genetic terminology is used throughout and the lesson begins with a check on their ability to identify the definition of homologous chromosomes. Students will recall that the sex chromosomes are not fully homologous and that the smaller Y chromosome lacks some of the genes that are found on the X. This leads into one of the numerous discussion points, where students are encouraged to consider whether females or males are more likely to suffer from sex-linked diseases and they will be challenged to find evidence to support this decision later in the lesson. In terms of humans, the lesson focuses on haemophilia and red-green colour blindness and a step-by-step guide is used to demonstrate how these specific genetic diagrams should be constructed and how the phenotypes should then be interpreted. The final tasks of the lesson challenge the students to carry out a dihybrid cross that involves a sex-linked disease and an autosomal disease before applying their knowledge to a question about chickens and how the rate of feather production in chicks can be used to determine gender.
All of the tasks are differentiated so that students of differing abilities can access the work and all exam questions have fully-explained, visual markschemes to allow them to assess their progress and address any misconceptions
