A Science teacher by trade, I've also been known to be found teaching Maths and PE! However, strange as it may seem, my real love is designing resources that can be used by other teachers to maximise the experience of the students. I am constantly thinking of new ways to engage a student with a topic and try to implement that in the design of the lessons.

This lesson has been designed to help students to explain the relationship between current and resistance in thermistors and LDRs. This can be a topic which students do not engage with or understand well, so this lesson has tried to add engagement with useful tips to deepen their knowledge. A number of quick competitions are used to introduce key terms such as semiconductor and then the key points explained. Students are given an exemplary answer for the thermistor so they can see how their work should be set out when trying to explain the graph produced by a LDR. Progress checks have been written into the lesson at regular intervals so that students can assess their understanding and any misconceptions can be addressed.
This lesson has been designed for GCSE students.
This bundle of 8 revision lessons have been designed to include a range of exam questions (with explained answers), differentiated tasks and quiz competitions to enable students to assess their understanding of the Pearson Edexcel A-level Biology A (Salters Nuffield) specification content.
The 8 topics that are covered in the specification are included in this bundle and are:
Topic 1: Lifestyle, Health and Risk
Topic 2: Genes and Health
Topic 3: Voice of the Genome
Topic 4: Biodiversity and natural resources
Topic 5: On the wild side
Topic 6: Infection, immunity and forensics
Topic 7: Run for your life
Topic 8: Grey matter
Students will enjoy the range of activities, which provide a much needed alternative to their other revision methods, and these lessons can be used throughout the duration of the course, as an end of topic revision lesson or in the lead up to mocks or the actual A-level terminal exams
This fully-resourced lesson looks at the effects of nervous mechanisms on the heart rate. The engaging and detailed PowerPoint and accompanying resources have been designed to cover the part of point 5.1.5 (k) 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 control of the heart rate by the cardiovascular centre in the medulla oblongata
This lesson begins with a prior knowledge check where students have to identify and correct any errors in a passage about the conduction system of the heart. This allows the SAN to be recalled as this structure play an important role as the effector in this control system. Moving forwards, the three key parts of a control system are recalled as the next part of the lesson will specifically look at the range of sensory receptors, the coordination centre and the effector. Students are introduced to chemoreceptors and baroreceptors and time is taken to ensure that the understanding of the stimuli detected by these receptors is complete and that they recognise the result is the conduction of an impulse along a neurone to the brain. A quick quiz is used to introduce the medulla oblongata as the location of the cardiovascular centre. The communication between this centre and the SAN through the autonomic nervous system can be poorly understood so detailed explanations are provided and the sympathetic and parasympathetic divisions compared. The final task challenges the students to demonstrate and apply their understanding by writing a detailed description of the control and this task has been differentiated three ways to allow differing abilities to access the work
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
The Pearson Edexcel A-level Biology A (Salters Nuffield) specification states that a minimum of 10% of the marks across the 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 lesson describes how genetic diversity within, or between species, can be investigated by comparison of characteristics or biological molecules. The PowerPoint and accompanying worksheets are primarily designed to cover the content of point 4.7 of the AQA A-level Biology specification but as this is the last lesson in the topic, it has also been planned to contain a range of questions, tasks and quiz rounds that will challenge the students on their knowledge and understanding of topic 4.
Over the course of the lesson, the students will discover that comparisons of measurable or observable characteristics, DNA and mRNA sequences and the primary structure of common proteins can all be used to investigate diversity. Links are continually made to prior learning, such as the existence of convergent evolution as evidence of the need to compare biological molecules as opposed to the simple comparison of phenotypes. The issues associated with a limited genetic diversity are discussed and the interesting biological example of the congenital dysfunctions consistently found in the Sumatran tigers in captivity in Australia and New Zealand is used to demonstrate the problems of a small gene pool. Moving forwards, the study of the 16S ribosomal RNA gene by Carl Woese is introduced and students will learn that this led to the adoption of the three-domain system in 1990. The final part of the lesson describes how the primary structure of proteins like cytochrome c that is involved in respiration and is therefore found in most living organisms can be compared and challenges the students to demonstrate their understanding of protein synthesis when considering the differences between humans and rhesus monkeys.
This concise lesson covers the content of specification point 5.1.5 (l) of the OCR A-level Biology A specification which states that students should be able to demonstrate and apply an understanding of the action of neuromuscular junctions. Due to a number of similarities between these structures and cholinergic synapses, this lesson uses prior knowledge of these connections between neurones to build a good understanding of the junctions. Students will discover that the events that occur at an axon tip mirror those which happen at the pre-synaptic bulb and this is then developed to look at the differences in terms of the events once the acetylcholine has bound to its receptor sites. There is a focus on the structure of the sarcolemma and time is taken to explain how the action potential is passed from this membrane to the transverse tubules in order to stimulate the release of calcium ions from the sarcoplasmic reticulum. As a result, this lesson ties in nicely with the following lesson on the contraction of skeletal muscle and students will be able to link the binding to troponin in that lesson to the release of these ions from this lesson.
Both of the main tasks of the lesson have been differentiated so that students of all abilities can access the work and make progress.
This lesson has been designed for those students studying on the OCR A-level Biology course and ties in nicely with the other uploaded lessons on module 5.1.5 (Animal and plant responses)
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.
The following sub-topics are covered in this bundle of lessons:
The use of genetic terminology
The inheritance of one or two genes in monohybrid and dihybrid crosses
Codominant and multiple alleles
The inheritance of sex-linked characteristics
Autosomal linkage
Epistasis as a gene interaction
The use of the chi-squared test
Species exist as one or more populations
The concepts of gene pool and allele frequency
Calculating allele frequencies using the Hardy-Weinberg principle
Causes of phenotypic variation
Stabilising, directional and disruptive selection
Genetic drift
Allopatric and sympatric speciation
Species, populations, communities and ecosystems
Factors affecting the populations in ecosystems
Estimating the size of a population using randomly placed quadrats, transects and the mark-release-recapture method
Primary succession, from colonisation by pioneer species to climax community
Conservation of habitats frequently involves the management of succession
This is one of the 8 topics which have to be covered over the length of the 2 year course and therefore it is expected that the teaching time for this bundle will be in excess of 2 months
If you want to see the quality of the lessons before purchasing then the lessons on codominant and multiple alleles, epistasis and phenotypic variation are free resources to download
This is a detailed and engaging lesson presentation (59 slides) that combines exam questions and progress checks along with quiz competition rounds to enable students to assess their understanding of the specification content within topics C1 - 3 of the OCR GCSE Combined Science Gateway A 9 - 1 as can be assessed in Paper 3.
All of the exam questions and progress checks have displayed answers as well as sections where content is recapped so that students can understand how an answer was obtained.
The revision rounds in the competition include “The need to BALANCE”, “Number crazy” and “React to the REACTION”.
This lesson has been designed for GCSE students.
This fully-resourced REVISION LESSON has been designed to provide the students with numerous opportunities to assess their understanding of the content of module 5.2.2 (Respiration) of the OCR A-level Biology A specification. The importance of this metabolic reaction is obvious and this is reflected in the volume of questions in the terminal exams which require an in depth knowledge of the stages of both aerobic and anaerobic respiration.
The lesson contains a wide range of activities that cover the following points of the specification:
Glycolysis as a stage of aerobic and anaerobic respiration
The use and production of ATP through respiration
Anaerobic respiration in mammalian muscle tissue
The stages of aerobic respiration that occur in the mitochondrial matrix
Oxidative phosphorylation
The use of respirometers
Calculating the respiratory quotient value for different respiratory substrates
Revision lessons which cover the other sub-modules of module 5 are uploaded and tie in well with this content
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 topics found within unit C9 (Chemistry of the atmosphere) of the AQA GCSE Combined Science specification (specification point C5.9).
The topics that are tested within the lesson include:
The proportion of different gases in the atmosphere
The Earth’s early atmosphere
Greenhouse gases
Atmospheric pollutants
Students will be engaged through the numerous quiz rounds whilst crucially being able to recognise those areas which require further attention
This fully-resourced lesson focuses on the events of meiosis which specifically contribute to genetic variation. The detailed PowerPoint and accompanying resources have been designed to cover the 4th and final part of point 4.3 of the AQA A-level Biology specification which states that students should be able to describe how meiosis produces daughter cells that are genetically different from each other.
In order to understand how the events of meiosis like crossing over and random assortment and independent segregation can lead to variation, students need to be clear in their understanding that DNA replication in interphase results in homologous chromosomes as pairs of sister chromatids. Therefore the beginning of the lesson focuses on the chromosomes in the parent cell and this first part of the cycle and students will be introduced to non-sister chromatids and the fact that they may contain different alleles which is important for the exchange that occurs during crossing over. Time is taken to go through this event in prophase I in a step by step guide so that the students can recognise that the result can be new combinations of alleles that were not present in the parent cell. Moving forwards, the lesson explores how the independent segregation of chromosomes and chromatids during anaphase I and II results in genetically different gametes. The final part of the lesson looks at the use of a mathematical expression to calculate the possible combinations of alleles in gametes as well as in a zygote following the random fertilisation of haploid gametes. Understanding and prior knowledge checks are interspersed throughout the lesson as well as a series of exam questions which challenge the students to apply their knowledge to potentially unfamiliar situations.
Due to the detail of this lesson, it is estimated that this will take about 2 hours of A-level teaching time to deliver
This is a fully-resourced revision resource which has been designed to encourage students to evaluate their understanding of the content in TOPIC 4 of the AQA A-level Biology specification (Genetic information, variation and relationships between organisms) . The resource includes an engaging PowerPoint (96 slides) and associated worksheets, some of which have been differentiated to allow those struggling with the content to access the work.
The wide range of activities which includes exam questions, quick tasks and quiz competitions will motivate the students whilst they assess their knowledge and recognise those areas which require even further attention. The lesson has been designed to cover as many sub-topics as possible but the following have been given particular attention:
Classification hierarchy
DNA in prokaryotes and eukaryotes
The binomial naming system
Phylogeny
Modern day classification using biological molecules
Calculating biodiversity
Selection pressures and types of selections
Transcription
Gene mutations
Physiological, behavioural and anatomical adaptations
Meiosis and variation
Non-disjunction
The mathematical element of this topic and the course is challenged throughout the lesson and helpful hints are regularly provided to help students to structure their answers. This resource can be used as a revision aid at the end of the topic, in the lead up to AS or A2 mocks or in the lead up to the actual terminal A-level exams.
An engaging lesson presentation (75 slides) and associated worksheets that uses a combination of exam questions, quick tasks and quiz competitions to help the students to assess their understanding of the topics found within unit B7(Ecology) of the AQA GCSE Biology specification (specification unit B4.7).
The topics that are tested within the lesson include:
Communities
Abiotic factors
Biotic factors
Levels of organisation
Recycling materials
Decomposition
Deforestation
Global warming

Pyramids of biomass
Transfer of biomass
Students will be engaged through the numerous activities including quiz rounds like “Number CRAZY" whilst crucially being able to recognise those areas which need further attention
This is a fully-resourced lesson that looks at the meaning of a limiting reactant in a chemical reaction and guides students through how to apply this to a number of calculations. Step by step guides are used to go through worked examples so students are able to visualise how to set out their work.
The lesson begins with a fun analogy involving sausages and potatoes so that students can identify that the potatoes limited the sale of food. Alongside this, students will learn the key term excess. Some time is then taken to ensure that students can spot the limiting reactant and the one in excess in actual chemical reactions and method descriptions. Moving forwards, students will be guided through two calculations that involve limiting reactants - those to calculate the theoretical yield and the other to calculate a balanced symbol equation. Other skills involved in these calculations such as calculating the relative formula mass are recalled and a few examples given to ensure they are confident. The question worksheet has been differentiated two ways so that any students who need extra assistance can still access the learning.
This lesson has been written for GCSE students.
An engaging lesson presentation (70 slides) and associated worksheets that uses a combination of exam questions, quick tasks and quiz competitions to help the students to assess their understanding of the topics found within unit C2 (Bonding, structure and properties of matter) of the AQA GCSE Combined Science specification (specification point C5.2)
The topics that are tested within the lesson include:
Chemical bonds
Ionic bonding
Ionic compounds
Properties of ionic compounds
Covalent bonding
Metallic bonding
Properties of metals and alloys
The three states of matter
State symbols
Structure and bonding of carbon
Students will be engaged through the numerous activities including quiz rounds like “The name’s BOND…” whilst crucially being able to recognise those areas which need further attention
This bundle of 6 revision lessons challenges the students on their knowledge of the content of all of the topics that are detailed in the Edexcel GCSE Combined Science specification and can be assessed on the 6 terminal GCSE papers. Specifically, the range of tasks which include exam-style questions (with displayed answers), quiz competitions and discussion points, have been designed for students taking the FOUNDATION TIER papers but could also be used with students taking the higher tier who need to ensure that the key points are embedded on some topics.
The majority of the tasks are differentiated 2 or 3 ways so that a range of abilities can access the work whilst remaining challenged by the content.

This lesson describes the uses and implications of pre-implantation genetic diagnosis, amniocentesis and chorionic villus sampling. The lesson PowerPoint and accompanying worksheets have been primarily designed to cover point 2.15 of the Pearson Edexcel A-level Biology A (Salters Nuffield) specification but regular links are made to the earlier content of topics 1 & 2, and their knowledge of topics including the heart and circulation, monohybrid inheritance and cystic fibrosis are tested.
The lesson begins by challenging them to use this prior knowledge of topic 2 to identify the letters in the abbreviations PGD and CVS. The involvement of IVF to obtain the embryos (or oocytes) is then discussed and a series of exam-style questions are used to get them to understand how this method screens embryos prior to implantation, so that those identified as having genetic diseases or being carriers are not inserted into the female’s uterus. Mark schemes for all of the questions included in this lesson are embedded into the PowerPoint so students can constantly assess their progress.
Moving forwards, Down syndrome (trisomy 21) is used as an example of a chromosomal abnormality that can be tested for using CVS or amniocentesis. Time is taken to describe the key details of both of these procedures so students have a clear understanding of the implications and the invasiveness to the female being tested. The link between amniocentesis and an increased risk of miscarriage is considered and the results of a 2006 study are used to challenge them on their data skills.
This lesson describes how to obtain and use sampling results to calculate an estimate for the population size of a sessile, slow-moving or motile organism. The PowerPoint and accompanying worksheets are part of the second lesson in a series of 4 lessons that have been designed to cover the content of topic 7.4 (Populations in ecosystems) of the AQA A-level Biology specification and includes descriptions of the use of randomly placed quadrats, quadrats along a belt transect and the mark-release-recapture method.
As you can see from the image, step by step guides are included in the lesson that walk the students through each stage of the calculations and these are followed by opportunities to challenge their understanding by answering exam-style questions. Mark schemes for the 7 questions that are answered over the course of the lesson are embedded into the PowerPoint and this allows the students to assess their progress. When considering the mark-release-recapture method, the assumptions that are made and the precautions that need to be taken are considered and the students are challenged to link the changes in the numbers of rabbits to the topic of stabilising selection.
A highly engaging lesson that looks at the structures that are found in the 1st line of defence and explores the methods of action use by phagocytes and lymphocytes. This lesson has been designed for GCSE students but could be used as an initial recap with A-level students before they go on to learn this topic in greater detail
The lesson begins by introducing the meaning of the 1st line of defence. A quick competition is used to challenge the students to recognise the names of some of these structures when their names have some letters missing. Time is taken to discuss the action of the cilia and skin and then students are challenged to make links to the related topics of enzymes and pH as they complete a passage about the role of hydrochloric acid in the stomach. Moving forwards, students will learn that there are two types of white blood cells, phagocytes and lymphocytes, and the details of their actions is explored. Key points such as the specificity of antibodies and the involvement of enzymes are discussed in detail so that this topic can be understood to the depth needed at this level. In addition to a number of games to maintain engagement, progress checks are written into this at regular intervals to allow the students to assess their understanding.
