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.

All 3 lessons included in this bundle are highly detailed and contain multiple biological examples to challenge the students to apply their understanding of a potentially difficult topic. A variety of tasks are embedded throughout the lessons and cover all of the content of topic 7.2 of the Edexcel A-level biology B specification (Factors affecting gene expression).
If you would like to view the quality of the lessons before deciding on the bundle, then download the epigenetic modification lesson as this has been shared for free.
This lesson describes how epigenetic changes like DNA methylation and histone modification can modify the activation of certain genes. The PowerPoint and accompanying resources have been planned to cover points 3.14 ii & iii of the Pearson Edexcel A-level biology (Salters-Nuffield) specification.
The lesson begins by introducing the prefix epi- as meaning on or above in Greek to allow students to recognise that epigenetics refers to changes in gene function due to factors beyond the genetic code. Moving forwards, they will learn that DNA methylation involves the attachment of a methyl group to cytosine and will come to understand how this inhibits transcription. They are challenged to recognise the pathogenesis of atherosclerosis through a variety of tasks before reading through a source detailing the results of a study between this cardiovascular condition and DNA methylation.
The remainder of the lesson considers how the acetylation of histone proteins affects the expression of genes.
Understanding and prior knowledge checks are embedded throughout the lesson (along with the answers) to allow the students to assess their progress on this topic and to encourage them to make links to the content of topics 1 - 2.
This bundle contains 5 detailed and engaging lessons, which have been planned to contain a variety of tasks that enable students to assess their understanding of the current topic and encourages them to make links to previously covered topics.
The lessons cover the following content from topic 8.2 of the AQA A-level biology specification:
Totipotent, pluripotent, multipotent and unipotent cells
iPS cells
The stimulation or inhibition of the transcription of target genes
Epigenetic control of gene expression by increased DNA methylation and decreased acetylation of histones
The inhibition of translation of target mRNA by RNA interference
The main characteristics of benign and malignant tumours

This lesson describes how iPS cells are formed from fibroblasts and discusses why this method is less controversial than the use of embryonic stem cells. The PowerPoint and accompanying resources are part of the 2nd lesson in a series of 2 lessons which covers the content of point 7.3 (stem cells) of the Edexcel A-level biology B specification.
The lesson begins with a SPOT THE ERRORS task, where students have to use their knowledge of pluripotent cells from the previous lesson to identify the 3 errors and make corrections. The aim of this task is to remind them that pluripotent cells are found in embryos and can divide in unlimited numbers before finally becoming fully differentiated somatic cells.
Moving forwards, the students are introduced to fibroblasts as examples of these somatic cells and the opportunity is taken to challenge their knowledge of collagen as this is a substance produced by these cells. The answers are embedded into the PowerPoint to allow the students to assess their recall of this topic 1 content. A quick quiz is used to introduce the acronym iPS and students will learn that fibroblasts can be reprogrammed to form induced pluripotent cells using specific transcription factors. The remainder of the lesson challenges them to answer questions about the use of iPS cells in regenerative medicine after reading a passage about an example. This allows them to recognise that deriving these cells from adult tissues as opposed to embryonic stem cells raises less problems and the transplant into the same person reduces the risk of rejection.
This bundle contains 4 complete lessons, with each one fully-resourced and consisting of a variety of tasks. These tasks include exam-based questions, understanding and prior knowledge checks and quiz rounds which will engage the students whilst covering the content of topic 7.4 in detail.

At the end of topic 3, or in the lead up to mocks or final A-level exams, students can use this lesson to assess their understanding of topic 3 content. The lesson consists of 20 multiple-choice questions, which have been written to challenge the students on the detail of their knowledge, as well as a PowerPoint which contains the answers, explanations and key points related to the specification. The PowerPoint also contains other topic 3 knowledge checks on content which isn’t directly questioned in the multiple-choice assessment, and prior knowledge checks to encourage the students to recognise the links to topic 1 and 2.
The following topics are challenged by the multiple-choice questions:
Surface area to volume ratio
Gas exchange (in animals and plants)
Digestion and absorption
Mass transport in animals
Mass transport in plants
This revision lesson contains an assessment of 20 multiple-choice questions and a PowerPoint with the answers and related key points from the specification. The 20 questions have been written to cover the content of topic 4 of the AQA A-level biology specification, providing the students with an opportunity to assess their understanding and highlight those areas which need further attention.
All 7 sub-topics of topic 4 are covered by at least one question and there are several questions which challenge mathematical skills, which aligns with the high mathematical content of the final assessments.
This lesson describes how only part of a cell’s DNA is translated and explains how the potency of a stem cell determines its ability to specialise. The engaging and detailed PowerPoint and accompanying resources have been planned to cover all of the content in point 8.2.1 of the AQA A-level biology specification.
The lesson begins by challenging the students to recall any existing knowledge of stem cells, to check that they remember that these cells differentiate, before the concept of cell potency is introduced to allow them to recognise that not all cells can differentiate into the same amount of cell types. A quick quiz is used to introduce pluripotency, unipotency, totipotency and multipotency before they are challenged to use their understanding of language to order these along the potency continuum. Beginning with totipotency, time is taken to go through details of each of these cell types, including where these cells are located. During the section of the lesson considering pluripotency, induced pluripotent stem cells are discussed and their potential for use in regenerative medicine is explored. Understanding checks through exam-based questions are embedded throughout the lesson (as well as the answers) to allow students to assess their current understanding and to address any gaps immediately. There are also prior knowledge checks so students can link to other topics from the specification and there is a maths in biology question so their mathematical skills are challenged in line with that element of the course.
This fully-resourced lesson describes the stages of succession from colonisation to climax community. The PowerPoint and accompanying worksheets have been designed to cover the content of point 5.4 of the Edexcel A-level Biology A specification.
As you can see from the cover image, this lesson uses a step-by-step method to guide the students through each stage of the process of succession, explaining each of the gradual, progressive changes that occur in a community over time. At each stage, time is taken to consider the organisms involved. There is a focus on lichens as examples of pioneer species and students will understand how colonisation by these organisms is critical to provide organic matter and to turn the bare ground into soil so it is habitable by other species. The island of Surtsey in Iceland is used as real-world example and shows how different parts of an area can be at different stages of succession.
Understanding and prior knowledge checks are embedded into the PowerPoint (along with the answers) to allow students to assess their progress against the current topic and to encourage them to make links to previously-covered work.
This lesson describes how recombinant DNA can be produced, including the role of restriction endonucleases and DNA ligase. The PowerPoint and accompanying resources have been designed to cover the content of point 7.4 (i) of the Edexcel A-level Biology B specification.
This lesson begins with the introduction of recombinant DNA technology as a process where fragments of DNA are transferred from one species to another. Over the course of the lesson, the students are guided through 5 steps in the production of the recombinant DNA, with a focus on the enzymes involved, which are reverse transcriptase, DNA polymerase, restriction endonuclease, and DNA ligase. Understanding checks and prior knowledge checks are used throughout the lesson and the answers are embedded into the PowerPoint to allow the students to assess their progress.
This detailed lesson describes the processes of PCR and electrophoresis to allow students to understand how gene sequencing can be used. The engaging PowerPoint and accompanying resource have been planned to cover the content of point 7.1 of the Edexcel A-level biology B specification.
The lesson begins by comparing the number of genes in the genome with the number of base pairs, to allow students to learn that the bases in the genes only accounts for about 1.5% of the genome. This challenges them to recall that most is non-coding DNA, and the importance and usefulness of these sections are explored during the lesson. Moving forward, a step-by-step guide describes the key steps in the polymerase chain reaction, and time is taken at each step to qualify the fine details such as the use of Taq polymerase instead of human DNA polymerase.
The remainder of the lesson focuses on the various uses of these DNA samples once they’ve been amplified by the PCR. The steps of the electrophoresis process are described and students will see how DNA profiling can be used in forensic science to identify criminals and for paternity tests.
Understanding and prior knowledge checks are found throughout the lesson, along with the answers, to allow students to assess their grasp of the current topic as well as their ability to identify the links with previously covered topics.
This bundle contains 7 detailed and engaging lessons which guide students through the key processes involved in modern genetics.

This revision lesson provides students with the opportunity to assess their understanding of nucleic acids and protein synthesis (topic 6). The lesson includes a multiple-choice assessment of 10 questions and a PowerPoint containing the answers, where each answer slide shows the exact specification code to enable students to note the areas which may require extra attention. The PowerPoint also contains additional questions to challenge content from topic 6 of the CIE A-level biology specification (2025 - 2027 update) that isn’t directly covered by the 10 questions, and prior knowledge checks to encourage students to make links to content from topics 1 - 5.
This lesson has been designed to be used at the end of topic 6, and in the build up to mocks and the final A-level assessments.
This revision lesson uses a 20 question multiple-choice assessment to challenge the students on their understanding of the topic 2 content (Cells). It has been written to check their knowledge from across the AQA A-level biology topic 2 specification and includes questions on the structure of eukaryotic and prokaryotic cells, the methods of studying cells, mitosis and binary fission, transport across cell membranes and the immune system. The lesson includes a PowerPoint where the answers to the 20 questions are revealed, along with their respective specification codes, to allow the students to pinpoint areas of the specification that require extra attention. The PowerPoint also includes extra questions and tasks to challenge some of the content not directly questioned in the MC assessment.
Lessons challenging their knowledge of topics 1, 3 and 4 have also been uploaded.
This revision lesson uses a multiple-choice assessment to challenge the students on their understanding of topic 8, the control of gene expression. In addition to the 20 question assessment, this lesson includes a PowerPoint where the answers are revealed and additional questions are posed about the content of topic 8 which isn’t directly challenged in the questions. The PowerPoint also contains prior knowledge checks on content from topics 1, 3, 4 and 6.
Revision lessons of this format which challenge topics 1 - 7 are also uploaded.
This bundle contains 5 detailed lessons which have been intricately planned to cover the content of topic 8.4 of the AQA A-level biology specification, which is titled “Gene technologies allow the study and alteration of gene function allowing a better understanding of organism function and the design of new industrial and medical processes”.
Each lesson contains real-world examples to increase the relevance of the content and is full of tasks as well as understanding and prior knowledge checks.

This lesson explains how labelled DNA probes can be used to screen patients for heritable conditions, their responses to drugs and to identify health risks. The PowerPoint and accompanying resources have been designed to cover the content of point 8.4.2 of the AQA A-level biology specification.
The lesson begins by introducing the BRCA genes, and the students will learn how faulty alleles of these two genes can increase an individual’s risk of developing breast cancer. Therefore, there is a need to be able to locate specific alleles like these, and this function is performed by DNA probes. The students are challenged to use the function of the probes to predict their structure and will understand that they are short lengths of single stranded DNA that have a base sequence complementary to the base sequence of part of the target allele. As shown in the cover image, a quick quiz round is used to introduce hybridisation as key term, to ensure that students recognise that the probe will bind if the complementary base sequence is encountered. Moving forwards, a DNA microarray is introduced to show that it’s possible to screen for multiple genes.
The remainder of the lesson considers how the DNA probes are used to screen for heritable conditions and drug responses, and real-life examples are used to increase relevance.
Prior knowledge checks are embedded throughout the lesson to encourage the students to make links to content from earlier topics including inheritance and genetic drift.
This lesson guides students through the stages of the nitrogen cycle, focusing on the vital roles performed by microorganisms in this cycle. The detailed PowerPoint and accompanying resources are part of the 1st lesson in a series of 3 lessons which have been planned to cover point 5.4 (nutrient cycles) of the AQA A-level biology specification.
The lesson begins by challenging students to recall two monomers containing nitrogen that were met in topic 1, allowing them to recognise that this chemical element is a key component of nucleotides in DNA and amino acids, which are needed to synthesise proteins. Moving forwards, they will learn that despite the high % of nitrogen in the Earth’s atmosphere, it cannot be used directly by plants, and therefore plants need a supply of “fixed” nitrogen. A diagram is constantly updated and displayed as new information is introduced and this supports their understanding. The students will discover that microorganisms are involved in nitrogen fixation, decomposition and ammonification, nitrification, and denitrification. As each of these biological actions is introduced, time is spent considering key details and understanding checks are used to allow the students to assess their progress. There are also several prior knowledge checks, where students are encouraged to make links to content met in topics 1 - 4. Answers to all questions are embedded into the PowerPoint.
This bundle includes 4 revision lessons which use multiple-choice questions to challenge the students on their knowledge and understanding of the content of topics 5 - 8 of the AQA A-level biology specification. Each lesson includes a multiple-choice assessment, consisting of 20 questions from across the topic, and a PowerPoint that contains the answers (with explanations), as well as additional questions that challenge the students to add detail and also check on prior knowledge.
