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 covers the part of specification point 7.1 of the AQA A-level Biology specification which states that students should be able to use genetic diagrams to interpret the results of crosses involving codominant and multiple alleles. The inheritance of ABO blood groups has three alleles at the gene locus on chromosome 9 where the alleles for A and B are codominant and this is used to introduce the two concepts. A range of tasks challenges the students to write genotypes, and construct genetic diagrams to calculate phenotypic ratios. They have to apply their understanding by working out the blood groups for a number of family members when presented with an incomplete pedigree tree. The final task of the lesson challenges their application skills further but this time, the animals involved are not humans. Each question is followed by a detailed, visual mark scheme so students can assess their progress and address any misconceptions
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 acts as an introduction to topic 7.1 of the AQA A-level Biology specification and focuses on 16 key genetic terms that will support students in forming a deep understanding of inheritance. As some of these terms were met at GCSE, this fully-resourced lesson has been designed to include a wide range of activities that build on this prior knowledge and provide clear explanations as to their meanings as well as numerous examples of their use in both questions and exemplary answers. The main task provides the students with an opportunity to apply their understanding by recognising a dominance hierarchy in a multiple alleles characteristic and then calculating a phenotypic ratio when given a completed genetic diagram. Other tasks include prior knowledge checks, discussion points to encourage students to consider the implementation of the genetic terms and quiz competitions to introduce new terms, maintain engagement and act as an understanding check.
The 16 terms are genome, gene, chromosome, gene locus, homologous chromosomes, alleles, dominant, recessive, genotype, codominance, multiple alleles, autosomes, sex chromosomes, phenotype, homozygous and heterozygous
This lesson has been designed to cover the detail of specification point 4.5.3.2 of the AQA GCSE Combined Science FOUNDATION TIER which states that students should be able to describe how the body detects and responds to an increase in blood glucose concentration. A considerable amount of time has been taken in the planning to ensure that the wide range of activities engages and motivates the students but that the key details are covered and understanding is checked and checked again.
The start of the lesson uses a range of prior knowledge checks and quiz competitions to answer the questions of what actually is glucose and why is it so important that the levels in the blood are controlled. Students are then introduced to glycogen and the fact that this carbohydrate can be stored is reiterated so that they can recognise how glucose must be converted into this substance to lower the blood concentration. Again, a quiz round is used to get them to recall that the pancreas will be the receptor and the liver will act as the effector. The main task of the lesson involves the formation of a bullet point answer where students are challenged to use the information from earlier in the lesson to complete this description.

Revision lessons for the other 18 topics are uploaded on TES or are in the process of being uploaded.
This engaging REVISION lesson has been designed to cover the content of topic 3 (Enzymes) of the CIE International A-level Biology specification. A wide range of activities have been written into the lesson to engage the students whilst they assess their understanding of the topic content. All of the exam questions contain detailed answers which students can use to identify missed marks and quiz competitions are used, like FROM NUMBERS 2 LETTERS (shown in the cover image) to recall key concepts and check on the finer details.
The lesson has been planned to cover as much of the specification content as possible but the following sub-topics have received particular attention:
Enzymes as globular proteins that act as biological catalysts
Formation of the enzyme-substrate complex
The lock and key theory and induced-fit hypothesis
Competitive and non-competitive inhibitors
The Michaelis-Menten constant
The effect of changes in pH and temperature on the tertiary structure of the enzymes
The immobilisation of enzymes using alginate
Time has been taken in the design to ensure that links to other topics are made. For example, when checking the knowledge of the denaturation of enzymes due to pH and temperature, the bonds found in the tertiary structure are recalled and considered in depth.
This is a fully-resourced and engaging REVISION LESSON which challenges the students on their knowledge and understanding of the topic 2 content (Biological molecules) of the CIE International A-level Biology specification. This topic isn’t always well understood by students so the lesson has been designed to include a wide range of activities that include differentiated exam questions, quick tasks and quiz competitions which will engage the students whilst they assess their progress. It has been designed to cover as much of the specification as possible but the following sub-topics have received particular attention:
Formation of polysaccharides by glycosidic bonds between monomers

This concise lesson has been written to cover the detail of specification point 14.1 (d) of the CIE International A-level Biology specification which states that students should be able to describe the deamination of amino acids and outline the formation of urea in the urea cycle. Over the course of the lesson, students will discover that the amino group is removed during deamination to produce a keto acid and ammonia. They are encouraged to consider why the ammonia cannot accumulate in the body before looking at the different stages of the urea cycle. Instead of simply giving them the diagram of the urea cycle, students are given the opportunity to study the cycle when it is split into one of the three stages but are not allowed to draw. This task will challenge the students on their observational skills and then their ability to apply when they are given a question on the cycle. Included throughout the lesson are a selection of understanding checks and prior knowledge checks which allows the students to assess their progress against the current topic as well as challenging them to make links to previously covered topics.
This lesson has been designed for students on the CIE International A-level Biology course and ties in well with the other uploaded lessons on topic 14.1 (Homeostasis in mammals)
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
This detailed and engaging lesson covers the detail of specification points 5.1.4 (c and d) of the OCR A-level Biology A specification which states that students should be able to demonstrate and apply an understanding of the histology of the pancreas and the control of insulin secretion. There is a particular emphasis on structure throughout the lesson so that students can recognise the exocrine and endocrine tissues of the pancreas as well as describe their specific functions.
The lesson begins with a list of endocrine glands and the students are challenged to select the gland which also has exocrine functions. This leads into a focus on the exocrine tissues of the pancreas, beginning with the enzymes that are secreted and form pancreatic juice. Students will discover how groups of these cells are called acini and the secretion of the enzymes into the lobule at the centre will lead to the intralobular ducts and finally the formation of the pancreatic duct. Moving forwards, students are introduced to the Islets of Langerhans and the specialised alpha and beta cells that are found within this endocrine tissue. The rest of this lesson looks at how the release of insulin from the beta cells is controlled. Some of the structures and substances involved have been met in earlier topics so a fun quiz round is used to see which students can recall these parts first. A series of questions and discussion points challenge the students to verbalise answers and to discuss key points so that the cascade of events that take place in the lead up to the release can be considered. In the final task, students have to describe these events in detail and this task has been differentiated so that students of differing abilities can access the work.
This lesson has been specifically designed for students on the OCR A-level Biology A course and ties in well with the other lessons from module 5.1.4 on the control of blood glucose concentration and diabetes mellitus type I and II

This fully-resourced lesson is highly detailed and covers all of specification points 14.1 (h, i and j) of the CIE International A-level Biology specification which states that students should be able to describe how blood glucose concentration is regulated using negative feedback mechanisms that release insulin or glucagon and outline the role of cyclic AMP. A wide range of activities will maintain motivation and engagement whilst the content is covered in detail to enable the students to explain how the receptors in the pancreas detect the concentration change and how the hormones attaching to receptor sites on the liver triggers a series of events in this effector organ. This is a topic which has a huge amount of difficult terminology so time is taken to look at all of the key words, especially those which begin with the letter G so students are able to use them accurately in the correct context. The final part of the lesson looks at the role of the secondary messenger, cyclic AMP, and describes how this is involved when glucagon and adrenaline attach to receptors on the liver. The action of adrenaline is also considered and linked to the breakdown of glycogen to glucose during glycogenolysis.
This lesson has been written for students studying on the CIE International A-level Biology course and ties in with the other uploaded lessons which cover the content of topic 14.1 (Homeostasis in mammals)
This is a highly-detailed and fully-resourced lesson which covers the detail of specification point 14.1 (g) of the CIE International A-level Biology specification which states that students should be able to describe the roles of the hypothalamus, posterior pituitary, ADH and collecting ducts in osmoregulation. Students learnt about the principles of homeostasis and negative feedback in an earlier lesson, so this lesson acts to build on that knowledge and challenges them to apply their knowledge. A wide range of activities have been included in the lesson to maintain motivation and engagement whilst the understanding and prior knowledge checks will allow the students to assess their progress as well as challenge themselves to make links to other Biology topics.
The lesson begins with a discussion about how the percentage of water in urine can and will change depending on the blood water potential. Students will quickly be introduced to osmoregulation and they will learn that the osmoreceptors and the osmoregulatory centre are found in the hypothalamus. A considerable amount of time is taken to study the cell signalling between the hypothalamus and the posterior pituitary gland by looking at the specialised neurones (neurosecretory cells). Links are made to the topics of neurones, nerve impulses and synapses and the students are challenged to recall the cell body, axon and vesicles. The main section of the lesson forms a detailed description of the body’s detection and response to a low blood water potential. The students are guided through this section as they are given 2 or 3 options for each stage and they have to use their knowledge to select the correct statement. The final task asks the students to write a detailed description for the opposite stimulus and this task is differentiated so those who need extra assistance can still access the work.
This lesson has been written for students studying on the CIE International A-level Biology course and ties in closely with the other uploaded lessons on the structure of the kidney, ultrafiltration and selective reabsorption
