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 looks at the series of oxidation-reduction reactions that form the Krebs cycle and focuses on the products in terms of reduced NAD, FAD and ATP. The engaging PowerPoint and accompanying resource have both been designed to cover the fifth part of point 5.2 of the AQA A-level Biology specification.
The lesson begins with a version of the Impossible game where students have to spot the connection between 8 of the 9 terms and will ultimately learn that this next stage is called the Krebs cycle. The main part of the lesson challenges the students to use descriptions of the main steps of the cycle to continue their diagram of the reactions. Students are continually exposed to key terminology such as decarboxylation and dehydrogenation and they will learn where carbon dioxide is lost and reduced NAD and FAD are generated. They will also recognise that ATP is synthesised by substrate level phosphorylation. The final task challenges them to apply their knowledge of the cycle to work out the numbers of the different products and to calculate the number of ATP that must be produced in the next stage
This lesson has been designed to tie in with the other uploaded lessons on glycolysis, anaerobic respiration, the Link reaction and oxidative phosphorylation.
This clear and concise lesson looks at the role of the Link reaction in the conversion of pyruvate to acetyl coenzyme A which will then enter the Krebs cycle. The PowerPoint has been designed to cover the fourth part of point 5.2 of the AQA A-level Biology specification which states that students should know about this conversion and the production of reduced NAD
The lesson begins with a challenge, where the students have to recall the details of glycolysis in order to form the word matrix. This introduces the key point that this stage occurs in this part of the mitochondria and time is taken to explain why the reactions occur in the matrix as opposed to the cytoplasm like glycolysis. Moving forwards, the Link reaction is covered in 5 detailed bullet points and students have to add the key information to these points using their prior knowledge as well as knowledge provided in terms of NAD. The students will recognise that this reaction occurs twice per molecule of glucose and a quick quiz competition is used to test their understanding of the numbers of the different products of this stage. This is just one of the range of methods that are used to check understanding and all answers are explained to allow students to assess their progress.
This lesson has been written to tie in with the other uploaded lessons on glycolysis and the Krebs cycle and oxidative phosphorylation.
This lesson looks at the detailed structure of DNA and builds on the knowledge from topic 1 to explain how this nucleic acid differs in the nucleus, mitochondria and chloroplasts of eukaryotic cells and in prokaryotic cells. Both the engaging PowerPoint and accompanying resources have been designed to cover the first part of point 6.1 (b) of the CIE International A-level Biology specification.
As well as focusing on the differences between the DNA found in these two types of cells which includes the length, shape and association with histones, the various tasks will ensure that students are confident to describe how this double-stranded polynucleotide is held together by hydrogen and phosphodiester bonds. These tasks include exam-style questions which challenge the application of knowledge as well as a few quiz competitions to maintain engagement.
This detailed lesson explains how the process of transcription results in the production of messenger RNA (mRNA). Both the detailed PowerPoint and accompanying resource have been designed to specifically cover the first part of point 6.2 (d) of the CIE International A-level Biology specification.
The lesson begins by challenging the students to recall that most of the nuclear DNA in eukaryotes does not code for polypeptides. This allows the promoter region and terminator region to be introduced, along with the structural gene. Through the use of an engaging quiz competition, students will learn that the strand of DNA involved in transcription is known as the template strand and the other strand is the coding strand. Links to previous lessons on DNA and RNA structure are made throughout and students are continuously challenged on their prior knowledge as well as they current understanding of the lesson topic. Moving forwards, the actual process of transcription is covered in a 7 step bullet point description where the students are asked to complete each passage using the information previously provided. An exam-style question is used to check on their understanding before the final task of the lesson looks at the journey of mRNA to the ribosome for the next stage of translation.
This lesson has been written to challenge all abilities whilst ensuring that the most important details are fully explained.
This lesson focuses on the structure of RNA and specifically the similarities and differences between this nucleic acid and DNA. The engaging and detailed PowerPoint and accompanying resource have been designed to cover the second part of point 6.1 (b) of the CIE International A-level Biology specification which states that students should be able to describe the structure of this nucleic acid. Students were introduced to the detailed structure of a nucleotide and DNA in previous lessons, so this lesson is written to tie in with those and continuously challenge prior knowledge as well as the understanding of the current topic.
The lesson begins with the introduction of RNA as a member of the family of nucleic acids and this enables students to recognise that this polynuclotide shares a number of structural features that were previously seen in DNA. A quiz round called “A FAMILY AFFAIR” is used to challenge their knowledge of DNA to recognise those features that are also found on RNA such as the chain of linked nucleotides, pentose sugars, nitrogenous bases and phosphodiester bonds. The next task pushes them to consider features that have not been mentioned and therefore are differences as they answer a structured exam-style question on how RNA differs from DNA. Students will learn that RNA is shorter than DNA and this leads into the final part of the lesson where mRNA and tRNA are introduced and again they are challenged to use the new information explain the difference in size. Brief details of transcription and then translation are provided so that students are prepared for the upcoming lessons on protein synthesis
Each of the 6 lessons which are included in this bundle have been written to specifically cover the content as detailed in topics 6.1 & 6.2 of the CIE International A-level Biology specification. The wide range of activities will maintain engagement whilst supporting the explanations of the biological knowledge to allow the students to build a deep understanding of nucleic acids and protein synthesis
Lessons which cover the following specification points are included in this bundle:
Structure of DNA and RNA

This detailed and engaging lesson looks at the culture of transformed host cells as an in vivo method to amplify DNA fragments. Both the PowerPoint and accompanying resources have been designed to cover the third part of point 8.4.1 of the AQA A-level Biology specification and ties in with the previous two lessons in this sub-topic on producing DNA fragments and the polymerase chain reaction.
The lesson begins with the introduction of the terms transgenic and transformed. Students will learn that bacterial cells are the most commonly transformed cells so the next task challenges their recall of the structures of these cells so that plasmid DNA can be examined from that point onwards. A quick quiz competition is used to introduce the key term, vector, and then the rest of the lesson looks at the details of the five steps involved in the transformation of the host cell:
Remove and prepare the plasmid to act as a vector
Insert the DNA fragment into the vector
Transfer the recombinant plasmid into the host cell
Identify the cells which have taken up the recombinant plasmid
All the transformed host cells to replicate and express the novel gene
Time is taken to explore the finer details of each step such as the addition of the promoter and terminator regions, use of the same restriction enzyme to cut the plasmid as was used to cut the gene and the different types of marker genes. Links are continuously made to the previous lessons in this topic so that students feel confident to answer assessment questions which bring in knowledge from all of the sections.
Each of the 4 lessons in this bundle are fully-resourced and have been designed to cover the content as detailed in topic 6.2 (Protein synthesis) of the CIE International A-Level Biology specification. The specification points that are covered within these lessons include:
A polypeptide is coded for by a gene
A gene mutation is a change in the sequence of nucleotides
Sickle cell anaemia results from a change in the amino acid sequence
Transcription as the production of mRNA from DNA
Information on DNA is used during translation to construct polypeptides
The lessons have been written to include a wide range of activities and numerous understanding and prior knowledge checks so students can assess their progress against the current topic as well as be challenged to make links to other topics within this topic and earlier topics

This detailed lesson describes the role of the mRNA, tRNA, amino acids and the ribosome during the second stage of protein synthesis - translation. Both the PowerPoint and accompanying resources have been designed to cover the third part of point 4.2 of the AQA A-level Biology specification and ties in with the previous lessons in this topic on RNA and transcription.
Translation is a topic which is often poorly understood and so this lesson has been written to enable the students to understand how to answer the different types of questions by knowing and including the key details of the structures involved. The lesson begins by challenging the students to consider why it is so important that the amino acids are assembled in the correct order during the formation of the chain. Moving forwards, a quick quiz round called “LOST IN TRANSLATION” is used to check on their prior knowledge of the mRNA strand, the tRNA molecules, the genetic code and the ribosomes. The next task involves a very detailed description of translation that has been divided into 14 statements which the students have to put into the correct order. By giving them a passage that consists of this considerable detail, they can pick out the important parts to use in the next task where they have to answer shorter questions worth between 3 and 4 marks. These types of questions are common in the assessments and by building up through the lesson, their confidence to answer this type should increase. The final two tasks of the lesson involve another quiz, where the teams compete to transcribe and translate in the quickest time before using all that they have learnt to answer some questions which involve the genetic code and the mRNA codon table.
This detailed lesson describes the role of the strand of mRNA, the tRNA molecules, the amino acids and the ribosome during the second stage of protein synthesis - translation.

This is a fully-resourced lesson which uses exam-style questions, quiz competitions, quick tasks and discussion points to challenge students on their understanding of topics P5 - P7, that will assessed on PAPER 6. It has been specifically designed for students on the AQA GCSE Combined Science course who will be taking the FOUNDATION TIER examinations but is also suitable for students taking the higher tier who need to ensure that the fundamentals are known and understood.
The lesson has been written to cover as many specification points as possible but the following sub-topics have been given particular attention:
Factors affecting the thinking, braking and stopping distance
The 7 recall and apply equations tested in PAPER 6
Using velocity-time graphs to calculate accelerations
The motions represented by the different lines on a velocity-time graph
Resultant forces
Speed and velocity as scalar and vector quantities
Converting between units
Sound as an example of a longitudinal wave
The EM spectrum
The meaning of amplitude, wavelength, frequency and period
Contact and non-contact forces
Attraction and repulsion in magnets
Magnetic fields
The extension of a spring
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 extra support 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 calculating acceleration and the mathematical elements
Due to the extensiveness of this revision lesson, it is estimated that it will take in excess of 2/3 teaching hours to complete the tasks and therefore this can be used at different points throughout the course as well as acting as a final revision before the PAPER 6 exam.
This lesson describes and explains how the contraction of the heart chambers during atrial and ventricular systole and the relaxation during diastole causes blood to flow through the heart. The engaging PowerPoint and accompanying resource have been designed to cover the first part of point B3 of UNIT 2 of the Pearson BTEC Level 3 National Diploma in Sport and Exercise Science specification.
The students will have already encountered aspects of the cardiac cycle in unit 1 and this lesson aims to build on that knowledge. Students will be reminded that the sequence of events known as the cardiac cycle can be split into three parts, which are atrial systole, ventricular systole and diastole. There is a particular focus on the role of the AV and semi-lunar valves in the control of blood flow and students are challenged to explain how pressure changes cause these valves to open or close. The final task of the lesson involves a quiz round called “RECYCLE THIS?” where the teams have to use their knowledge of the cardiac cycle and the function and anatomy of the heart and blood vessels from a previous lesson to spot any errors in the description of blood flow through the heart
This lesson has been specifically designed to tie in with the next lesson outlined in the specification on the neural control of the cardiac cycle
This fully-resourced lesson describes the structure of the heart as well as the associated blood vessels. Both the engaging PowerPoint and accompanying differentiated resources have been designed to cover the 1st part of point 1.2.5 as detailed in the Edexcel A-level PE specification which states that students need to learn about the anatomical components and structure of the heart.
The structure of the heart is a topic which was covered in part at GCSE so this lesson has been written to build on that prior knowledge. The main task of the lesson involves students labelling the different structures as they are recalled. Time is taken at different points of the lesson to look at some of the structures and concepts in further detail. For example, students will learn that humans have a double circulatory system, as detailed in point 1.2.6, and that the thicker muscular wall of the left ventricle allows the blood in the systemic circulation to be pumped at a higher pressure than in the pulmonary circulation. Students are also challenged to explain why a hole in the septum would cause health issues for an affected individual and this links back to previous work in unit 1 on energy systems.
By the end of the lesson, the students will be able to identify the following structures and describe their individual functions:
right and left atria
right and left ventricles
septum
tricuspid and bicuspid valve
semi-lunar valves
pulmonary artery and pulmonary vein
vena cava
aorta
A number of quiz rounds are used throughout the lesson to introduce key terms in a fun and memorable way before the final round is used as a final check so they can assess whether they can recognise the structures and recall their functions.
This lesson describes and explains how the contraction of the heart chambers during atrial and ventricular systole and the relaxation during diastole causes blood to flow through the heart. The engaging PowerPoint and accompanying resource have been designed to cover the first part of point 1.2.6 as detailed in the Edexcel A-level PE specification which states that students need to learn about the physiology of the cardiovascular system with regards to the cardiac cycle.
The students will have already encountered aspects of the cardiovascular system in topic 1.2.5 and this lesson aims to build on that knowledge. Students will be introduced to the sequence of events known as the cardiac cycle and will learn that the cycle can be split into three parts, which are atrial systole, ventricular systole and diastole.

This engaging lesson describes the relationship between the structure and properties of a phopholipid and explains the link to its role in membranes. The PowerPoint has been designed to cover the second part of point 1.3 of the AQA A-level Biology specification and includes constant references to the previous lesson on triglycerides.
The role of a phospholipid in a cell membrane provides the backbone to the whole lesson. A quick quiz round called FAMILY AFFAIR, challenges the students to use their knowledge of the structure of a triglyceride to identify the shared features in a phospholipid. This then allows the differences to be introduced, such as the presence of a phosphate group in place of the third fatty acid. Moving forwards, the students will learn that the two fatty acid tails are hydrophobic whilst the phosphate head is hydrophilic which leads into a key discussion point where the class has to consider how it is possible for the phospholipids to be arranged when both the inside and outside of a cell is an aqueous solution. The outcome of the discussion is the introduction of the bilayer which is critical for the lesson in topic 2 on the fluid mosaic model. The final part of the lesson explains how both facilitated diffusion and active transport mean that proteins are found floating in the cell membrane and this also helps to briefly prepare the students for upcoming topic 2 lessons.
Disaccharides are formed from the condensation of two monosaccharides and this lesson describes the formation of maltose, sucrose and lactose. The PowerPoint and accompanying question sheet have been designed to cover the second part of point 1.2 of the AQA A-level Biology specification but also make links to the previous lesson on monosaccharides when considering the different components of these three disaccharides.
The first section of the lesson focuses on a prefix and a suffix so that the students can recognise that the names of the common disaccharides end in -ose. In line with this, a quick quiz round is used to introduce maltose, sucrose and lactose before students are challenged on their prior knowledge as they have to describe how condensation reactions and the formation of glycosidic bonds were involved in the synthesis of each one. The main task of the lesson again challenges the students to recall details of a previous lesson as they have to identify the monomers of each disaccharide when presented with the displayed formula. Time is taken to show how their knowledge of these simple sugars will be important in later topics such as digestion, translocation in the phloem and the Lac Operon in the control of gene expression. The lesson finishes with two exam-style questions where students have to demonstrate and apply their newly acquired knowledge
This fully-resourced lesson describes the process of DNA replication and explains how this ensures genetic continuity between generations. Both the detailed PowerPoint and accompanying resources have been designed to cover point 1.5.2 of the AQA A-level Biology specification and also explains why it is known as semi-conservative.
The main focus of this lesson is the roles of DNA helicase in the breaking the hydrogen bonds between nucleotide bases and DNA polymerase in forming the growing nucleotide strands. Students are also introduced to DNA ligase to enable them to understand how this enzyme functions to join the nucleic acid fragments. Time is taken to explain key details, such as the assembly of strands in the 5’-to-3’ direction, so that the continuous manner in which the leading strand is synthesised can be compared against that of the lagging strand. The students are constantly challenged to make links to previous topics such as DNA structure and hydrolysis reactions through a range of exam questions and answers are displayed so that any misconceptions are quickly addressed. The main task of the lesson asks the students to use the information provided in the lesson to order the sequence of events in DNA replication before discussing how the presence of a conserved strand and a newly built strand in each new DNA molecule shows that it is semi-conservative.
