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 describes why a disease would be deemed to be an autoimmune disease and describes the mechanisms involved in a few examples. The PowerPoint and accompanying worksheets have been primarily designed to cover point 4.1.1 (k) of the OCR A-level Biology A specification, but this lesson can also be used to revise the content of modules 2 and 3 and the previous lessons in 4.1.1 through the range of activities included
The lesson begins with a challenge, where the students have to recognise diseases from descriptions and use the first letters of their names to form the term, autoimmune. In doing so, the students will immediately learn that rheumatoid arthritis, ulcerative colitis, type I diabetes mellitus, multiple sclerosis and myasthenia gravis are all examples of autoimmune diseases. The next part of the lesson focuses on the mechanism of these diseases where the immune system cells do not recognise the antigens (self-antigens) on the outside of the healthy cells, and therefore treats them as foreign antigens, resulting in the production of autoantibodies against proteins on these healthy cells and tissues. Key details of the autoimmune diseases stated above and lupus are described and links to previously covered topics as well as to future topics such as the nervous system are made. The students will be challenged by numerous exam-style questions, all of which have mark schemes embedded into the PowerPoint to allow for immediate assessment of progress.
This lesson bundle contains 5 fully-resourced lessons which will engage and motivate the students whilst covering the content of module 5.2.1 of the OCR-A-level Biology A specification in the depth of detail required to support them to answer assessment questions on this topic of PHOTOSYNTHESIS confidently. This cellular reaction can be poorly understood by students so intricate planning has gone into the design of the lesson PowerPoints and accompanying resources to ensure that key details are embedded and reinforced throughout and that knowledge acquired in previous lessons is regularly checked.
The following specification points are covered by the lessons in this bundle:
The structure of the chloroplasts and the two main stages of photosynthesis
The light-dependent stage of photosynthesis
The fixation of carbon dioxide and the light-independent stage of photosynthesis
The uses of triose phosphate
Factors affecting photosynthesis

A fully-resourced lesson, designed for GCSE students which includes an engaging and informative lesson presentation (49 slides) and an image, actual and magnification question worksheet. This lesson looks at the key features of light and electron microscopes and guides students through calculating size and magnification.
The lesson begins by challenging students to pick out two key terms about microscopes, magnification and resolution, from a group of Scientific words. The understanding of these two terms is critical if students will be able to compare the two types of microscopes so time is taken to go through the definitions and give examples. A number of quick quiz competitions have been written into the lesson to aid the engagement on a topic that some students may not initially consider to be that motivating. These competitions allow key terms such as micrometer and the two types of electron microscope to be introduced in an engaging way. As a result, students will know the numbers that explain why electron microscopes are more advanced than their light counterparts. The remainder of the lesson looks at the units of size which are used in calculation questions and a step by step guide is used to show the students to calculate the actual size of an object or the magnification.
Progress checks have been written into this lesson at regular intervals so that students are constantly assessing their understanding.
This lesson looks at the two stages of protein synthesis, transcription and translation, and focuses on the key details that students need to understand this potentially difficult topic. The lesson presentation has been deliberately written in a concise way to encourage the students to summarise the two stages and pick out the key points which will enable them to form longer answers when necessary. The lesson begins by introducing the students to RNA, and a quick check is done to see how much they can recall about the other nucleic acid, DNA. Moving forwards, students are challenged to study the structure of DNA and RNA in SPOT THE DIFFERENCE before being challenged to explain why RNA is necessary in this process. Time is taken to look at important sections such as complimentary base pairing and the identification of amino acids from the codon. A number of quick competitions have been written into the lesson to maintain engagement and the progress checks are regular so that students assess their understanding and any misconceptions can be quickly identified and addressed.
This lesson has been written for GCSE students but should a teacher want to teach an introduction lesson on protein synthesis before going into more detail at a later date, then this would be suitable.
Each of the 13 lessons included in this bundle are fully-resourced and have been designed to cover the content as detailed in module 6.1.2 (Patterns of inheritance) of the OCR A-Level Biology A specification. The specification points that are covered within these lessons include:

The students will thoroughly enjoy the range of activities, which include quiz competitions such as "Can I have a P please BOB” where they have to recognise the different phases of mitosis from pictures or descriptions. The activities will crucially enable the students to determine which areas of topic 2 will 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 GCSE exams.
This is a fully-resourced REVISION lesson that uses a combination of exam questions, understanding checks, differentiated tasks and quiz competitions to enable students to assess their understanding of the content found within Topic 3.3 (Organisms exchange substances with their environment) of the AQA A-level Biology specification.
The sub-topics and specification points that are tested within the lesson include:
Surface area to volume ratio
Gas exchange
Digestion and absorption
Mass transport in animals
Mass transport in plants
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 A-level terminal exams
This is a fully-resourced REVISION resource that consists of an engaging PowerPoint (127 slides) and associated worksheets that challenge the students on their knowledge of topic 7 (Genetics, populations, evolution and ecosystems) of the AQA A-level Biology specification.
A wide range of activities have been written into this resource to maintain motivation and these tasks include exam questions (with answers), understanding checks, differentiated tasks and quiz competitions.
The lesson has been designed to cover as much of the content as possible, but the following sub-topics have been given particular attention:
Genetic terminology
Using genetic diagrams to calculate phenotypic ratios and percentages for the inheritance of a single gene
Applying the Hardy-Weinberg principle
Sex-linkage
Codominance, multiple alleles and interpreting genetic trees
Types of variation
Ecological terminology
Dihybrid inheritance
Using the chi-squared test to determine significance
Epistasis
Succession
Sampling to estimate populations and consider distribution
The mathematic elements of this topic and specification are challenged throughout the resource and useful hints given to enable the students to pick up vital marks from questions on this topic.
Due to the size of this resource, teachers may choose to use it over the course of a number of lessons and it is suitable for use at the end of topic 7, in the lead up to the mocks or in the lead up to the actual A-level exams.
This concise lesson acts as an introduction to topic 5.3, Energy and Ecosystems, and describes how plant biomass is formed, measured and estimated. The engaging PowerPoint is the 1st in a series of 3 lessons which have been designed to cover the detailed content of topic 5.3 of the AQA A-level Biology specification.
A quiz round called REVERSE Biology Bingo runs throughout the lesson and challenges students to recognise the following key terms from descriptions called out by the bingo caller:
community
ecosystem
abiotic factor
photosynthesis
respiratory substrate
biomass
calorimetry
The ultimate aim of this quiz format is to support the students to understand that any sugars produced by photosynthesis that are not used as respiratory substrates are used to form biological molecules that form the biomass of a plant and that this can be estimated using calorimetry. Due to the clear link to photosynthesis, a series of prior knowledge checks are used to challenge the students on their knowledge of this cellular reaction but as this is the first lesson in the topic, the final section of the lesson looks forwards and introduces the chemical energy store in the plant biomass as NPP and students will also meet GPP and R so they are partially prepared for the next lesson.
This bundle contains 20 lesson PowerPoints which are highly detailed to ensure that the topic 7 content is covered at the depth required for A-level Biology. The lessons have been intricately planned to contain a wide variety of tasks that will engage and motivate the students whilst covering the current material and to make links to other lessons in this topic as well as to the previous 6 topics.

This lesson describes how large molecules are hydrolysed to smaller molecules by the enzymes produced by the digestive system in mammals. The detailed PowerPoint and accompanying worksheets are part of the 1st lesson in a series of 2 which have been designed to cover the content of point 3.3 of the AQA A-level Biology specification and this lesson includes descriptions of the action of amylase, disaccharidases, lipase, endopeptidases, exopeptidases and dipeptidases.
The lesson has been designed to walk the students through the functions of the digestive system at each point of the digestive tract up until the duodenum and focuses on the action of the enzymes produced in the mouth, stomach and small intestine and by the accessory organs of the system. Time is taken to describe and explain key details, such as the fact that endopeptidases cleave peptide bonds within the molecules, meaning that they cannot break down proteins into monomers. The lesson is filled with exam-style questions which will develop their understanding of the current topic as well as checking on their knowledge of related topics which have been previously-covered such as the structure of the biological molecules and qualitative tests. In addition to the detailed content and regular questioning, the lesson PowerPoint contains guided discussion periods and two quick quiz competitions which introduce a key term and a key value in a fun and memorable way
This lesson has been specifically planned to prepare the students for the very next lesson where the mechanisms for the absorption of the products of digestion are described.

This engaging and fully-resourced lesson looks at examples of stabilising, directional and disruptive selection as the three main types of selection. The PowerPoint and accompanying resources have been designed to cover the 1st part of point 6.1.2 (e) of the OCR A-level Biology specification which states that students should be able to demonstrate and apply an understanding of the factors that affect the evolution of a species.
The lesson begins by making a link to a topic from module 4 as the students are challenged to use the mark, release, recapture method to calculate numbers of rabbits with different coloured fur in a particular habitat. Sketch graphs are then constructed to show the changes in the population size in this example. A quick quiz competition is used to engage the students whilst introducing the names of the three main types of selection before a class discussion point encourages the students to recognise which specific type of selection is represented by the rabbits. Key terminology including intermediate and extreme phenotypes and selection pressure are used to emphasise their importance during explanations. A change in the environment of the habitat and a change in the numbers of the rabbits introduces directional selection before students will be given time to discuss and to predict the shape of the sketch graph for disruptive selection. Students are challenged to apply their knowledge in the final task of the lesson by choosing the correct type of selection when presented with details of a population and answer related questions.
This lesson has been designed to tie in with another uploaded lesson on genetic drift which covers the second part of this specification point.
All 7 of the lessons in this bundle are fully-resourced and have been designed to cover the content as detailed in topic 5.2 (Respiration) of the AQA A-Level Biology specification. The specification points that are covered within these lessons include:

This fully-resourced lesson describes the process of skeletal muscle contraction in terms of the sliding filament theory. The engaging and detailed PowerPoint and accompanying resources have been designed to cover point 7.2 of the Pearson Edexcel A-level Biology A (Salters Nuffield) specification and includes the role of actin, myosin, troponin, tropomyosin, calcium ions and ATP.
The lesson begins with a study of the structure of the thick and thin filaments. Students will recognise that the protruding heads of the myosin molecule are mobile and this enables this protein to bind to the binding sites when they are exposed on actin. This leads into the introduction of troponin and tropomyosin and key details about the binding of calcium to this complex is explained. Moving forwards, students are encouraged to discuss possible reasons that can explain how the sarcomere narrows during contraction when the filaments remain the same length. This main part of the lesson goes through the main steps of the sliding filament model of muscle contraction and the critical roles of the calcium ions and ATP are discussed. The final task of the lesson challenges the students to apply their knowledge by describing the immediate effect on muscle contraction when one of the elements doesn’t function correctly.
This lesson has been written to tie in with another uploaded lesson on the structure of a muscle fibre which is covered in specification point 7.10
