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 fully-resourced lesson describes how the eukaryotic cells of complex multicellular organisms become specialised for specific functions. The detailed and engaging PowerPoint and accompanying resources have been designed to cover the 3rd part of point 2.1.1 of the AQA A-level Biology specification and also describes how these specialised cells are organised into tissues, organs and organ systems.
The start of the lesson focuses on the difference in the SA/V ratio of an amoeba and a human in order to begin to explain why the process of differentiation is critical for multicellular organisms. Students will discover that a zygote is a stem cell which can express all of the genes in its genome and divide by mitosis. Time is then taken to introduce gene expression as this will need to be understood in the later topics of the course. Moving forwards, the lesson uses the process of haematopoiesis from haematopoietic stem cells to demonstrate how the red blood cell and neutrophil differ significantly in structure despite arising from the same cell along the same cell lineage. A series of exam-style questions will not only challenge their knowledge of structure but also their ability to apply this knowledge to unfamiliar situations. These differences in cell structure is further exemplified by the epithelial cells of the respiratory tract and students will understand why the shape and arrangement of these cells differ in the trachea and alveoli in line with function. The link between specialised cells and tissues is made at this point of the lesson with these examples of epithelium and students will also see how tissues are grouped into organs and then into organ systems.
The remainder of the lesson focuses on specialised plant cells and the differing shapes and features of the palisade and spongy mesophyll cells and the guard cells are covered at length and in detail. Step by step guides will support the students so that they can recognise the importance of the structures and links are made to upcoming topics such as diffusion, active transport and osmosis so that students are prepared for these when covered in the future.
This lesson has been written to continually tie in with the previous two lessons in this specification point which are uploaded under the titles of the structure of eukaryotic animal and plant cells.
This fully-resourced lesson challenges the students to use fully labelled genetic diagrams to interpret the results of monohybrid and dihybrid crosses as detailed in topic 7.1 (Inheritance) of the AQA A-level Biology specification. Step-by-step guides are used to demonstrate how diagrams for the inheritance of one and two genes should be constructed and a focus is given to the areas where students commonly make mistakes, such as in writing out the gametes. The main task of each section of the lesson provides an opportunity for the students to apply their understanding by calculating phenotypic ratios. All of the questions have fully-explained mark schemes and students can assess their progress and address any misconceptions immediately. Key genetic terminology is used throughout the lesson and mirrors that used in actual exam questions.
This lesson describes the meaning of biodiversity, explains how it relates to a range of habitats, and describes how to calculate an index of diversity. The PowerPoint and accompanying worksheets are part of the first in a series of 2 lessons that have been designed to cover the content of topic 4.6 of the AQA A-level Biology specification. The second lesson describes the balance between conservation and farming.
A quiz competition called BIOLOGICAL TERMINOLOGY SNAP runs over the course of the lesson and this will engage the students whilst challenging them to recognise species, population, biodiversity, community and natural selection from their respective definitions. Once biodiversity as the variety of living organisms in a habitat is revealed, the students will learn that this can relate to a range of habitats, from those in the local area to the Earth. When considering the biodiversity of a local habitat, the need for sampling is discussed and some key details are provided to initially prepare the students for these lessons in topic 7. Moving forwards, the students will learn that it is possible to measure biodiversity within a habitat, within a species and within different habitats so that they can be compared. Species richness as a measure of the number of different species in a community is met and a biological example in the rainforests of Madagascar is used to increase its relevance. The students are introduced to an unfamiliar formula that calculates the heterozygosity index and are challenged to apply their knowledge to this situation, as well as linking a low H value to natural selection. The rest of the lesson focuses on the index of diversity and a 3-step guide is used to walk students through each part of the calculation. This is done in combination with a worked example to allow students to visualise how the formula should be applied to actual figures. Using the method, they will then calculate a value of d for a comparable habitat to allow the two values to be considered and the significance of a higher value is explained. All of the exam-style questions have mark schemes embedded in the PowerPoint to allow students to continuously assess their progress and understanding.
A detailed and engaging lesson presentation (52 slides) and accompanying worksheet that looks at competition between organisms and the different types of relationships that exist as a result of this interaction. The lesson begins by looking at the meaning of the biological term, "competition", and then introduces this when it occurs between the same species and different species. Students are challenged to consider the different resources that animals compete for before an activity based competition is used to get them to recognise how this competition can cause changes to the population size.
Moving forwards, students will meet the three main types of ecological relationship and look at them in greater detail, with predation being a main focus.
There are regular progress checks throughout the lesson (with displayed answers) so that students can assess their understanding.
This lesson has been designed for GCSE students but can be used with more-able KS3 students who are looking at ecosystems and the relationships that exist within them
An informative and engaging lesson (46 slides) that looks at the topic of immobilised enzymes and focusses on ensuring that students understand this topic around three main ideas. By the end of the lesson, students will be able to explain why immobilised enzymes are used, describe the different methods by which they are produced and describe some of their uses in biotechnology. Time is taken throughout the lesson to make sure that students understand the disadvantages associated with this process and that they are able to explain the specific limitations of each method.
This lesson has been designed for students studying A-level Biology
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

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 assistance sheets when they are unable to begin a question. Step-by-step guides have also been written into the lesson to walk students through some of the more difficult concepts such as genetic diagrams and evolution by natural selection.
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 duration of the course as well as acting as a final revision before the PAPER 1 exam.
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.

A fully-resourced lesson which has been designed for GCSE students and includes an engaging lesson presentation and associated worksheets. This lesson looks at the three limiting factors of photosynthesis, focusing on the graphs that they produce and ensures that students can explain why temperature is a factor.
This lesson begins by introducing the students to the definition of a limiting factor. They are challenged to recognise that it would be photosynthesis which is limited by carbon dioxide concentration and light intensity. The third factor, temperature, is not introduced until later in the lesson so that students are given thinking time to consider what it might be. Having been presented with two sets of data, students are asked to draw sketch graphs to represent the trend. The limiting factors on the light intensity graph are taught to the students so they can use this when working out the limiting factors on the carbon dioxide graph. The remainder of the lesson focuses on temperature and more specifically why a change in this factor would cause a change in the rate of photosynthesis because of enzymes. The student’s knowledge of that topic is tested alongside. Progress checks have been written into the lesson at regular intervals so that students can constantly assess their understanding.
All 4 of the lessons included in this bundle are highly-detailed to enable students to understand the sequence of events that occur during the body’s response to infection. Hours of planning have gone into the lesson PowerPoints and accompanying resources to ensure that the wide variety of tasks motivate and engage the students whilst challenging them to answer exam-style questions that cover the following specification points in topic 6.7 of the Edexcel A-level Biology B specification:
The mode of action of macrophages, neutrophils and lymphocytes
The development of the humoral immune response
The development of the cell-mediated response
The role of T and B memory cells in the secondary immune response
Immunity can be natural, artificial, active or passive
Vaccination can be used in the control of disease and the development of herd immunity
This can be a difficult topic for students to grasp, so time is taken to go over the key details to ensure that these are emphasised and retained
All 3 lessons included in this bundle are detailed and engaging and have been planned at length to cover the content of topic 5.3 of the AQA A-level biology specification, which is titled energy and ecosystems. The lessons contain a variety of tasks which introduce the biological content and then provide the students with opportunities to assess their understanding. There are also prior knowledge checks to make links to content from earlier in topic 5 and in topics 1 - 4. All the answers to the checks are embedded in the PowerPoint.

This detailed lesson describes each of the 4 stages of aerobic respiration and explains how this cellular reaction yields ATP and generates heat. The engaging PowerPoint and accompanying resource have been designed to cover points 5.1 (i) and (ii) of the Edexcel A-level Biology B specificaiton and acts as a clear introduction for the upcoming lessons where the finer details of glycolysis, the Link reaction and Krebs cycle and oxidative phosphorylation are described
The lesson begins with an introduction to glycolysis and students will learn how this first stage of aerobic respiration is also the first stage when oxygen is not present. This stage involves 10 reactions and an opportunity is taken to explain how each of these reactions is catalysed by a different, specific intracellular enzyme. A version of “GUESS WHO” challenges students to use a series of structural clues to whittle the 6 organelles down to just the mitochondrion so that they can learn how the other three stages take place inside this organelle. Moving forwards, the key components of the organelle are identified on a diagram. Students are introduced to the stages of respiration so that they can make a link to the parts of the cell and the mitochondria where each stage occurs. Students will learn that the presence of decarboxylase and dehydrogenase enzymes in the matrix along with coenzymes and oxaloacetate allows the link reaction and the Krebs cycle to run and that these stages produce the waste product of carbon dioxide. Finally, time is taken to introduce the electron transport chain and the enzyme, ATP synthase, so that students can begin to understand how the flow of protons across the inner membrane results in the production of ATP and the the formation of water when oxygen acts as the final electron acceptor.
As Biology is the study of living organisms which are built out of cells, a clear understanding of the topic of cell structure is critical for a student’s success in A-level Biology. Intricate planning has gone into all 7 of the lessons included in this bundle and the variety of tasks will engage and motivate the students whilst the details of the following specification points in topic 1 of the CIE A-level Biology course are covered:
Topic 1.1: The microscope in cell studies
Use an eyepiece graticule and stage micrometer to measure cells
Use of the millimetre, micrometre and nanometre
Distinguish between resolution and magnification
The use of light and electron microscopes
Calculate the actual sizes of specimens
Topic 1.2: Cells as the basic units of living organisms
Recognise eukaryotic cell structures and outline their functions
State that ATP is produced in the mitochondria and the chloroplast and the role of this molecule in cells
The structure of a typical prokaryotic cell
The differences between eukaryotic and prokaryotic cells
The key features of viruses

This fully-resourced lesson describes the ultrastructure of a prokaryotic cell including the nucleoid, plasmid, 70S ribosomes and cell wall. The engaging PowerPoint and accompanying resources have been designed to cover specification point 2.1 (iii) of the Edexcel A-level Biology B specification but has been specifically designed to be taught after the lesson on the ultrastructure of eukaryotic cells, specification point 2.1 (v), so that comparisons can be drawn.
A clear understanding of terminology is important for A-level Biology so this lesson begins with a challenge, where the students have to come up with a 3-letter prefix that they believe will translate as before or in front of . This leads into the discovery of the meaning of prokaryote as before nucleus which acts to remind students that these types of cell lack this cell structure. Links to the previous lessons on the eukaryotic cells are made throughout the lesson and at this particular point, the students are asked to work out why the DNA would be described as naked and to state where it will be found in the cell. Moving forwards, the students will discover that these cells also lack membrane bound organelles and a quick quiz competition challenges them to identify the specific structure that is absent from just a single word. In addition to the naked DNA, students will learn that there are also ribosomes in the cytoplasm and will discover that these are smaller than those found in the cytoplasm of an eukaryotic cell (but the same size as those in chloroplasts and mitochondria). The remainder of the lesson focuses on the composition of the cell wall, the additional features of prokaryotic cells such as plasmids and there is also the introduction of binary fission as the mechanism by which these organisms reproduce so that students can recognise that prokaryotic cells do not contain centrioles
As the first topic to be taught at the start at the second year of the Edexcel International A-level Biology course, topic 5 is very important and the content includes the key reaction of photosynthesis.
