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 bundle contains 6 fully-resourced lessons which have been designed to engage and motivate the students whilst covering the detailed content of topic 3 (Enzymes) in the CIE A-level Biology specification. These globular proteins catalyse biological reactions throughout living organisms so a deep understanding of this topic is important for all of the other 18 topics in this course.
The wide range of activities that are included within the lesson PowerPoints and accompanying resources will cover the following specification points:
Enzymes are globular proteins that catalyse reactions
The mode of action of enzymes
The lock and key hypothesis and the induced-fit model
The effect of temperature on the rate of an enzyme-catalysed reaction
The effect of pH on the rate of an enzyme-catalysed reaction
The effect of enzyme and substrate concentration on the rate of an enzyme-catalysed reaction
The effect of inhibitor concentration on the rate of an enzyme-catalysed reaction
The effect of competitive and non-competitive inhibitors on enzyme activity
Immobilising an enzyme in alginate
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
Normally the first topic to be taught in the second year of the AQA A-level Biology course, topic 5 contains some very important biological processes which include photosynthesis, respiration and energy transfer between organisms.

This lesson describes the principles of cell fractionation and ultracentrifugation as used to separate cell components. The engaging PowerPoint and accompanying resources are part of the final lesson in a series of 4 lessons which have been planned to cover the details of point 2.1.3 of the AQA A-level biology specification.
This lesson begins by informing the students that several of the key terms in this lesson, including the lesson title, end in -ation, and therefore they have to use the clues to work out that the 1st one is cell fractionation. A quiz round like this runs throughout the lesson, introducing homogenisation, filtration and ultracentrifugation in a memorable way. Time is taken to explain each of the processes in detail, and where possible, links are made to previously covered content as well as content that will be met in future lessons. For example, students will learn that the solution must be kept ice-cold and isotonic, and they are challenged to recognise that the low temperature is to reduce the activity of potentially damaging enzymes, before being told that there will be no net movement of water by osmosis because of the isotonic solution. The answers to all understanding and prior knowledge checks are embedded into the PowerPoint to allow students to assess their progress. When explaining the process of ultracentrifugation, the students are given an opportunity to predict which of 6 listed organelles will be found in the 1st pellet because it is the heaviest, right down to the lightest organelle. The lesson finishes with several exam-style questions to check that they’ve understood this separation technique and have a strong knowledge of cells and their organelles.
This lesson has been planned to continously link with the other lessons in topic 2.1 (Cell structure).
This lesson guides students through the use of the chi-squared test to determine the significance of the difference between observed and expected results. It is fully-resourced with a detailed PowerPoint and differentiated task worksheets that have been designed to cover the part of point 7.1 of the AQA A-level Biology specification which states that students should be able to use the test to compare the goodness of fit between the observed phenotypic ratios and expected ratios.
The lesson has been written to include a step-by-step guide that demonstrates how to carry out the test in small sections. At each step, time is taken to explain any parts which could cause confusion and helpful hints are provided to increase the likelihood of success in exam questions on this topic. Students will understand how to use the phenotypic ratio to calculate the expected numbers and then how to find the critical value in order to compare it against the chi-squared value. A worked example is used to show the working which will be required to access the marks and then the main task challenges the students to apply their knowledge to a series of questions of increasing difficulty.
This is the final lesson of topic 7.1 (inheritance) and links are made throughout the lesson to earlier parts of this topic such as dihybrid inheritance as well as to earlier topics such as meiosis.
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.
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 and associated worksheet that looks at the use of antibiotics to treat bacterial infections and the raises the issue of the potential over-use of these substances. The lesson begins by getting the students to recognise the difference between three key terms that begin with anti (antibiotics, antivirals, antiseptics). Students will be introduced to the idea that antibiotics are specific to a small range of bacteria and therefore the correct one has to be selected before being prescribed. Moving forwards, students will meet the idea of the zone of inhibition and will understand how the size of this zone can be used as an indicator to the effectiveness of the treatment. Students are shown how to calculate the size of the zone and then are tested on their ability to apply this mathemetical knowledge. Finally, time is taken to look at the links to the topic of natural selection to explain how some bacteria are resistant to certain antibiotics. There are regular progress checks throughout the lesson so that students can assess their understanding.
This lesson has been designed for GCSE students but could be used as an introduction with A-level Biology students who are about to begin the topic of immunity.
This engaging lesson looks at the structure of the quaternary protein, haemoglobin, and describes its role with red blood cells in the transport of oxygen. The PowerPoint has been designed to cover the first part of point 3.4.1 of the AQA A-level Biology specification and explains how the cooperative nature of binding results in a loading of each molecule with 4 oxygen molecules and describes how it is unloaded at the respiring cells too.
The lesson begins with a version of the quiz show Pointless to introduce haemotology as the study of the blood conditions. Students are told that haemoglobin has a quaternary structure and are challenged to use their prior knowledge of biological molecules to determine what this means for the protein. They will learn that each of the 4 polypeptide chains contains a haem group with an iron ion attached and that it is this group which has a high affinity for oxygen. Time is taken to discuss how this protein must be able to load (and unload) oxygen as well as transport the molecules to the respiring tissues. Students will plot the oxyhaemoglobin dissociation curve and the S-shaped curve is used to encourage discussions about the ease with which haemoglobin loads each molecule. Students will learn that a conformational change upon binding of the first oxygen leads to it being easier to bind future oxygens and that this is known as cooperative binding.
This lesson has been written to tie in with the other uploaded lesson on the Bohr effect.
This fully-resourced lesson looks at the blood circulation in a mammal and considers how the pulmonary circulation differs from the systemic circulation. The engaging PowerPoint and accompanying resources have been designed to cover the third part of point 3.4.1 of the AQA A-level Biology specification
The lesson begins with a focus on the double circulatory system and checks that students are clear in the understanding that the blood passes through the heart twice per cycle of the body. Beginning with the pulmonary circulation, students will recall that the pulmonary artery carries the blood from the right ventricle to the lungs. An opportunity is taken at this point to check on their knowledge of inhalation and the respiratory system as well as the gas exchange between the alveoli and the capillary bed. A quick quiz is used to introduce arterioles and students will learn that these blood vessels play a crucial role in the changes in blood pressure that prevent the capillaries from damage. When looking at the systemic circulation, time is taken to look at the coronary arteries and renal artery as students have to be aware of these vessels in addition to the ones associated with the heart. In the final part of the lesson, students are challenged to explain how the structure of the heart generates a higher pressure in the systemic circulation and then to explain why the differing pressures are necessary.
This lesson has been written to tie in with the other uploaded lessons from topic 3.4.1 (mass transport in animals)

This clear and detailed lesson describes the process of oxidative phosphorylation, including the roles of the electron carriers, oxygen and the mitochondrial cristae and explains the role of chemiosmosis. The PowerPoint has been designed to cover points 5.2.2 (g) and (h) of the OCR A-level Biology A specification and includes details of the electron transport chain, proton gradients and ATP synthase.
The lesson begins with a discussion about the starting point of the reaction. In the previous stages, the starting molecule was the final product of the last stage but in this stage, it is the reduced coenzymes which release their hydrogen atoms. Moving forwards, the process of oxidative phosphorylation is covered in 7 detailed steps and at each point, key facts are discussed and explored in further detail to enable a deep understanding to be developed. Students will see how the proton gradient across the inner membrane is created and that the flow of protons down the channel associated with ATP synthase results in a conformational change and the addition of phosphate groups to ADP by oxidative phosphorylation. Understanding checks are included throughout the lesson to enable the students to assess their progress and prior knowledge checks allow them to recognise the clear links to other topics and modules.
This lesson has been written to tie in with the other uploaded lessons on glycolysis, the Link reaction and Krebs cycle and anaerobic respiration
