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 can be used as revision resource at the end of the topic or in the lead up to mocks or the actual International GCSE exams
This is a fully-resourced lesson that covers the content of specification point 6.3 of the AQA A-level Biology specification which states that students should understand how skeletal muscles are stimulated to contract by nerves and act as effectors. The wide range of activities included in the lesson will engage and motivate the students whilst the understanding and previous knowledge checks will not only allow them to assess their progress but also challenge them to make links to other Biology topics.
The following content is covered in detail in this lesson:
The ultrastructure of a myofibril
The roles of actin and myosin in myofibril contraction
The need for calcium ions and ATP in myofibril contraction
The roles of calcium ions and tropomyosin in cross-bridge formation

This lesson has been designed for students studying the AQA A-level Biology course and ties in nicely with the other uploaded lessons from topic 6 such as synapses and NMJs and nerve impulses
This fully-resourced lesson looks at the use and interpretation of electrocardiogram (ECG) traces and focuses on their use in the diagnosis of CVD and other heart conditions. The engaging PowerPoint and accompanying resources have been designed to cover point 3.1.2 (h) of the OCR A-level Biology A specification and continual links are made to linked topics from earlier in this module
The lesson has been written to take place in an imaginary cardiology ward where the students are initially challenged on their knowledge of the symptoms and risk factors of CVD before looking at testing through the use of ECGs and diagnosis. The main focus of the lesson is the ECG and a quiz competition is used to introduce the reference points of P, QRS and T before time is taken to explain their representation with reference to the cardiac cycle. Moving forwards, a SPOT the DIFFERENCE task is used to challenge the students to recognise differences between sinus rhythm and some abnormal rhythms including tachycardia and atrial fibrillation. Bradycardia is used as a symptom of sinus node disfunction and the students are encouraged to discuss this symptom along with some others to try to diagnose this health problem.
A fully resourced revision lesson which uses a range of exam questions (with explained answers), quick tasks and quiz competitions to enable the students to assess their understanding of the topics found within module 5.1.4 (Hormonal communication) of the OCR A-level Biology A specification.
The topics tested within this lesson include:
Endocrine communication
Adrenal glands
The pancreas and the release of insulin
Regulating blood glucose
Diabetes
Student will enjoy the range of tasks and quiz rounds whilst crucially being able to recognise any areas which require further attention
This is an engaging revision lesson which uses a range of exam questions, understanding checks, quick tasks and quiz competitions to enable students to assess their understanding of the content within topic 1 (Characteristics and classification of living organisms) of the CIE IGCSE Biology specification, for examination in 2020 and 2021. The lesson covers the content in both the core and supplement sections of the specification and therefore can be used with students who will be taking the extended papers as well as the core papers.
The specification points that are covered in this revision lesson include:
CORE
Describe the characteristics of living organisms by defining the terms movement, respiration, sensitivity, growth, reproduction, excretion and nutrition
State that organisms can be classified into groups by the features that they share
Define and describe the binomial system of naming species as an internationally agreed system in which the scientific name of an organism is made up of two parts showing the genus and species

List the main features used to place all organisms into one of the five kingdoms: Animal, Plant, Fungus, Prokaryote, Protoctist
List the features of viruses, limited to protein coat and genetic material
The students will thoroughly enjoy the range of activities, which include quiz competitions such as “Are you the KING of the KINGDOMS” where they have to name the kingdoms involved based on a feature whilst crucially being able to recognise the areas of this topic which need their further attention. This lesson can be used as revision resource at the end of the topic or in the lead up to mocks or the actual IGCSE exams
This is a highly engaging, detailed and fully-resourced revision lesson which covers topics 4 & 5 of the Pearson Edexcel GCSE Physics specification. Due to the close links between the topics of waves and light and the electromagnetic spectrum, it was decided to design a single resource that challenged the students on their knowledge and understanding of the Physics detailed in these two topics.
The PowerPoint and acccompanying resource have been written to include a wide range of activities which include exam-style questions (with clearly explained answers), differentiated tasks and quick quiz competitions. These activities challenge the following specification points:
Define and use the terms frequency, wavelength, amplitude and period
Recall and use both of the equations to calculate wave speed
Describe how to measure the velocity of sound in air and ripples on water surfaces
Describe the effects of reflection and refraction
Explain how waves will be refracted at a boundary in terms of a change in direction and speed
Recall that sound waves can be ultrasound and infrasound

Explain, with the aid of diagrams, refraction, the critical angle and total internal reflection
Explain the difference between specular and diffuse reflection
Recall that the EM waves are transverse and travel at the speed of light in a vacuum
Describe the EM spectrum as continuous from radio waves to gamma rays
Describe the uses and harmful effects of the EM waves
To fall in line with the heavy mathematical content of the specification, there is a large emphasis on a range of mathematical skills in this lesson which includes rearranging formula, converting between units and using standard form.
Due to the detail of this lesson, it is estimated that it will take in excess of 2 hours of GCSE-allocated teaching time to cover the content and this allows this to be used at the end of the topic or in the lead up to mock or terminal examinations.
This lesson has been designed to cover the content of specification point 4.1.1.1 (Eukaryotes and prokaryotes) of the AQA GCSE Biology and Combined Science course. The understanding of this topic is fundamental to a lot of the later topics on the course so time has been taken to ensure that the key details are covered whilst engagement levels are kept high through the range of activities.
The lesson begins by asking students to copy a diagram of a bacterial cell from memory before challenging them to recognise anything that is missing so they can discover the lack of the nucleus. Students are introduced to the idea of a prokaryotic cell before important questions are answered such as the fact that the cell still has DNA despite the absence of the nucleus. Key terms such as plasmid are introduced to the students through the use of quiz competitions in an effort to increase the likelihood of these words being remembered. Moving forwards, eukaryotic cells are considered and the common features of both of the cells are discussed and recalled. Finally, students are asked to compare both types of cells in terms of their size before being challenged on a range of mathematical skills in which they have to convert between the units of centimetres, millimetres, micrometres and nanometres.
An engaging lesson presentation (65 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 B1 (Cell-level systems) of the OCR Gateway A GCSE Biology specification
The topics that are tested within the lesson include:
Plant and animal cells
Bacterial cells
Light and electron microscopy
DNA
Transcription and translation
Enzymes
Photosynthesis
Students will be engaged through the numerous activities including quiz rounds like “Shine a LIGHT on any errors" whilst crucially being able to recognise those areas which need further attention
This clear and concise lesson explains how the inheritance of two or more genes that have loci on the same chromosome demonstrates autosomal linkage. The engaging PowerPoint and associated resource have been designed to cover the part of point 16.2 (b) of the CIE International A-level Biology specification which states that students should be able to use genetic diagrams to solve problems that involve autosomal linkage.
This is a topic which can cause confusion for students so time was taken in the design to split the concept into small chunks. There is a clear focus on how the number of original phenotypes and recombinants can be used to determine linkage and suggest how the loci of the two genes compare. Important links to other topics such as crossing over in meiosis are made to enable students to understand how the random formation of the chiasma determines whether new phenotypes will be seen in the offspring or not. Linkage is an important cause of variation and the difference between observed and expected results and this is emphasised on a number of occasions. The main task of the lesson acts as an understanding check where students are challenged to analyse a set of results involving the inheritance of the ABO blood group gene and the nail-patella syndrome gene to determine whether they have loci on the same chromosome and if so, how close their loci would appear to be.
This detailed lesson explores how a range of methods are used to produce fragments of DNA as part of the recombinant DNA technology process. Both the engaging PowerPoint and accompanying resources have been written to cover the first part of point 8.4.1 of the AQA A-level Biology specification and also provides information that will prove useful for the other lessons in this sub-topic on the polymerase chain reaction and using transformed host cells.
The lesson begins with a definition of recombinant DNA technology so that students can begin to understand how this process involves the transfer of DNA fragments from one species to another. Links are made to the genetic code and transcription and translation mechanisms, which were met in topic 4, in order to explain how the transferred gene can be translated in the transgenic organism. Moving forwards, the method involving reverse transcriptase and DNA polymerase is introduced and their knowledge of the structure of the polynucleotides and the roles of enzymes is challenged through questions and discussion points. Restriction enzymes are then introduced and time is taken to look at the structure of a restriction site as well as the production of sticky ends due to the staggered cut on the DNA. A series of exam-style questions with displayed mark schemes are used to allow the students to assess their current understanding. The final part of the lesson looks at the production of synthetic genes of any sequence using gene machines and a series of application questions are used to push the students to consider how this advance in technology could be utilised.
As well as understanding and prior knowledge checks, quick quiz competitions are used throughout the lesson to introduce key terms such as cDNA and EcoR1 in a memorable way.
This fully-resourced lesson explores how genetic and environmental factors cause phenotypic variation. The engaging PowerPoint and accompanying worksheets have been designed to cover the first part of point 7.3 of the AQA A-level Biology specification which states that students should be able to describe how mutations and meiosis both contribute to genetic variation
Students are challenged at the start of the lesson to recognise the terms phenotype and species from their definitions in order to begin a discussion on the causes of the phenotypic variation within a species. Moving forwards, students will recall that mutations are the primary source of genetic variation and time is taken to look at the effect of gene and chromosome mutations. Just like the majority of parts of this specification point, gene mutations were covered earlier in topic 4 so these tasks act as a prior knowledge check as students have to recognise the different types of gene mutations and explain their effects on the primary structure with reference to the genetic code. These prior knowledge checks are found throughout the lesson and challenge the knowledge of other topics that include photosynthesis, meiosis and inorganic ions. The karyotype of an individual who has Down syndrome is used to introduce chromosome mutations and students will be introduced to the different types, with a focus on non-disjunction. The key events of meiosis that produce variation (crossing over and independent assortment) are explored and students will be given a mathematical formula to use to calculate the number of chromosome combinations in gametes and in the resulting zygote. The final part of the lesson looks at chlorosis and how an environmental factor can prevent the express of a gene.
This lesson describes how to calculate the mean and standard deviation of collected data and describes how these values may be interpreted. The PowerPoint and accompanying worksheets are part of the second lesson in a series of 2 lessons which have been designed to cover point 4.7 (Investigating diversity) of the AQA A-level Biology specification. It is important to note that the students will not be required to calculate the standard deviation in written papers but that they do need to understand how these values are obtained and what they could indicate.
The lesson begins with an introduction of the standard deviation as a measure of the spread around the mean. The students will learn that interpreting the data is a critical requirement of this A-level course and this initial portion of the lesson considers how the spread of the data around the mean can lead to differing suggestions about reliability. A step by step guide walks the students through each stage of the calculation of the standard deviation, which includes the calculation of the mean, and they will complete a worked example with the class. A quick quiz round introduces the values of 68 and 95 in a fun way to encourage the students to remember that if the focus of the data shows a normal distribution, 68% of the observations are within +/- one standard deviation and 95% are within 2 standard deviations. The final task challenges the students to apply their knowledge to data about the birth weights of humans at a UK hospital on one day in 2020.
This fully-resourced lesson has been designed to cover the specification point about co-dominance (and blood groups) as detailed in the supplement section of topic 17 (inheritance) of the CIE IGCSE Biology specification. As specified in this point, students will learn how this inheritance of the ABO blood group system demonstrates co-dominance (and also multiple alleles). A potentially difficult topic, time has been taken to include guidance sections where students are walked through the interpretation of the different genotypes to find out the phenotypes as well as constructing genetic diagrams and calculating blood groups from pedigree trees. There is a real focus on genetic terminology such as allele, locus, genotype and phenotype so that the understanding is deep and students can use this if they choose to further their studies at A-level.
This lesson has been designed for GCSE-aged students studying the CIE IGCSE Biology course but is also suitable for older students who are learning about codominance and multiple alleles at A-level
This is a highly detailed, engaging and fully-resourced lesson that covers the detail of the 2nd part of specification point 5.1.2 (b) of the OCR A-level Biology A specification which states that students should be able to demonstrate and apply an understanding of the functions of the mammalian liver. The liver performs a large number of metabolic functions and the majority of them are covered within this lesson. However, the lesson focuses on the following three roles:
The formation of urea by deamination and the ornithine cycle
The storage of glycogen
The detoxification of alcohol
As well as covering the detail of the current topic, numerous opportunities are taken to make links to other topics and to check on the students prior knowledge. Previous knowledge check questions on biological molecules, coenzymes and the structure of the liver are found dispersed within the understanding checks and quick quiz competitions are used to introduce key terms and values in a fun and a memorable way.
This lesson has been designed for students on the OCR A-level Biology A course and ties in well with the other uploaded lessons on module 5.1.2 about the structure and function of the kidney
An engaging lesson presentation (79 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 Topic 9 (Ecosystems and material cycles) of the EDEXCEL GCSE Biology specification
The topics that are tested within the lesson include:
Levels of organisation
Communities
Interdependence in a community
Determining the number of organisms in a given area
Biomass and the transfer of energy between trophic levels
Recycling materials
Deforestation

Decomposition and the rate of decay
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 fully-resourced lesson describes the roles of antigens, antibodies, B cells and T cells in the body’s immune response. The PowerPoint and accompanying worksheets have been designed to cover specification points 6.8 & 6.9 as detailed in the Pearson Edexcel A-level Biology A specification and includes descriptions of the involvement of plasma (effector) cells and macrophages as antigen-presenting cells.
In the previous lesson on the non-specific responses, the students were introduced to macrophages and dendritic cells as antigen-presenting cells and the start of this lesson challenges their recall and understanding of this process. Time is taken to discuss how the contact between these cells and lymphocytes is critical for the initiation of the body’s (specific) immune response. Moving forwards, a quick quiz competition is used to introduce the names of the different T cells that result from differentiation. Their specific roles are described including an emphasis on the importance of the release of cytokines in cell signalling to activate other immune system cells. T memory cells are also introduced so that students can understand their role in immunological memory and active immunity as described in an upcoming lesson covering point 6.12. The next part of the lesson focuses on the B cells and describes how clonal selection and clonal expansion results in the formation of memory B cells and effector cells. A series of understanding and application questions are then used to introduce the structure of antibodies and to explain how the complementary shape of the variable region allows the antigen-antibody complex to be formed. The lesson concludes by emphasising that the pathogen will be overcome as a result of the combination of the actions of phagocytes, T killer cells and the antibodies released by the effector cells.
A fully-resourced lesson which explores how the release of thyroxine from the thyroid gland regulates the metabolic rate and how a negative feedback loop is used as the final control. This lesson includes an engaging and detailed presentation (19 slides), a crossword and an understanding check task.
The lesson begins by challenging the students knowledge of the endocrine system to get them to come up with the letters that form the name, “thyroid gland”. Students will be reminded that this gland releases thyroxine which is involved with the regulation of the metabolic rate. Students will learn that in order for the thyroid gland to release this hormone, it has to be stimulated by TSH from the pituitary gland which in turn was controlled by the hypothalamus. At this point, the students are challenged to put the order of the control mechanism in the right order on their worksheet. This leads them to the word negative which links to how a negative feedback loop is used as the final act in the mechanism.
This lesson is designed for GCSE students but is suitable for A-level students too who need to know about this endocrine gland and also negative feedback
