A fully-resourced lesson that looks at the meaning of thinking, braking and stopping distances and focuses on the factors that would cause each of them to increase. The lesson includes an engaging lesson presentation (45 slides) and an associated worksheet for the calculations. The lesson begins by introducing the term stopping distance and then challenging students to recognise that both the distance travelled during the driver’s reaction time and under the braking force will contribute to this. Students are constantly challenged to think about the factors that would cause either the thinking or braking distance to increase and to be able to explain why scientifically. Moving forwards, the mathematical element that is associated with this topic is explored as students are shown how to calculate the braking distance at different speeds as well as convert between speeds in miles per hour and metres per second. There is also a set homework included as part of the lesson. There are regular progress checks written into the lesson so that students can assess their understanding. This lesson has been written for GCSE students but could be used with those at KS3.

This resource has been designed to cover the higher tier content of specification point 5.3.6 as detailed in the AQA GCSE Biology & Combined Science specifications. The lesson takes the format of a day at a fertility clinic and students will see how three couples, who are at different stages of their currently unsuccessful journey to getting pregnant, are advised and the treatments that could be on offer to them. Discussion points are included throughout the lesson to encourage the students to talk about the Biology and to allow any misconceptions to be addressed if and when they arise. In addition, previous knowledge checks are regular so that the links between this topic and earlier ones such as the hormones in human reproduction and contraception can be made. Students will learn how a fertility drug may be made available and will be challenged to explain why FSH and LH would be the reproductive hormones contained in these substances. The main focus of the lesson is IVF treatment and this main task culminates with students gaining a number of key points in the for and against argument before being challenged to continue this as a set homework in the form of an evaluation. Quiz competitions are used to introduce key terms in a fun and memorable way and the final task is a mathematical skills check where students will be able to compare the high number of multiple births that are associated with this treatment as compared to the number from natural births. This lesson has been designed for students studying the AQA GCSE Biology or Combined Science course but is suitable for older students who are looking at this topic.

This fully-resourced lesson has been designed to cover the content of specification point 5.2.2 (The brain) as found in topic 5 of the AQA GCSE Biology specification. This resource contains an engaging PowerPoint (33 slides) and accompanying worksheets, some of which have been differentiated so that students of different abilities can access the work. The resource is filled with a wide range of activities, each of which has been designed to engage and motivate the students whilst ensuring that the key Biological content is covered in detail. Understanding checks are included throughout so that the students can assess their grasp of the content. In addition, previous knowledge checks make links to content from earlier topics such as cancer. The following content is covered in this lesson: The functions of the cerebral cortex, medulla and cerebellum Identification of the regions of the brain on an external and internal diagram The early use of stroke victims to identify functions The key details of the MRI scanning technique The difficulties of diagnosing and treating brain disorders and disease As stated at the top, this lesson has been designed for GCSE-aged students who are studying the AQA GCSE Biology course, but it can be used with A-level students who need to go back over the key points before looking at the functionality of the regions in more detail

A fully-resourced lesson that explores how resistance, current and potential difference differ between series and parallel circuits. This knowledge needs to be sound in order for students to be able to carry out circuit calculations. The lesson includes a practical and task-based lesson presentation (24 slides) and an accompanying worksheet. The lesson begins by challenging the students to recognise the key difference between the two circuits, in that in a parallel circuits, the electrons can follow more than one route. Moving forwards, each physical factor is investigated in each type of circuits and students carry out tasks or calculations to back up any theory given. Helpful analogies and hints are provided to guide the students through this topic which is sometimes poorly understood. Students will be challenged to use the V = IR equation on a number of occasions so that they are comfortable to find out any of these three factors. Progress checks have been written into the lesson at regular intervals so that students are constantly assessing their understanding and any misconceptions can be addressed. This has been written for GCSE students, but could be potentially used with higher ability KS3 students.

A fully-resourced lesson which focuses on using the kinetic energy equation to calculate energy, mass and speed. The lesson includes a lesson presentation (23 slides) which guides students through the range of calculations and accompanying worksheets which are differentiated. The lesson begins with the students being drip fed the equation so they are clear on the different factors involved. They are challenged to predict whether increasing the mass or increasing the speed will have a greater effect on the kinetic energy before testing their mathematical skills to get results to support their prediction. Moving forwards, students are shown how to rearrange the equation to make the mass the subject of the formula so they can use their skills when asked to calculate the speed. The final task of the lesson brings all of the learning together to tackle a set of questions of increasing difficulty. These questions have been differentiated so that students who need extra assistance can still access the learning. This lesson has been written for GCSE students

This clear and concise lesson explores the importance of coenzymes in cellular respiration as detailed in point 5.2.2 (f) of the OCR A-level Biology A specification. Students encountered coenzymes in module 2.1.4 as well as looking at the roles of NAD, CoA and FAD whilst learning about glycolysis, the link reaction and Krebs cycle earlier in this module. Therefore this lesson was designed to check on their understanding of the importance of these roles and goes on to explain how the transport of the protons and electrons to the mitochondrial cristae is key for the production of ATP. This lesson has been written to tie in with the other uploaded lessons in module 5.2.2 which include the mitochondria, glycolysis, the link reaction and the Krebs cycle

This lesson describes how to use and manipulate the magnification formula to calculate the magnification or the actual size in a range of units. The PowerPoint and accompanying resources have been designed to cover point 2.1.1 (e) of the OCR A-level Biology A specification and contains a number of quiz rounds as part of the competition that runs throughout all of the module 2.1.1 lessons The students are likely to have met the magnification formula at GCSE so this lesson has been written to build on that knowledge and to support them with more difficult questions when they have to calculate actual size without directly being given the magnification. A step by step guide is used to walk the students through the methodology and useful tips are provided. Students could be asked to calculate the actual size in millimetres, micrometres, nanometres or picometres so time is taken to ensure that they can convert between one and another.

This lesson focuses on the degenerate nature of the genetic code and explains how a mutation may not result in a change to the sequence of amino acids. The PowerPoint has been designed to cover the first part of point 4.3 of the AQA A-level Biology specification and it makes links to the upcoming lesson on gene mutations. The lesson begins by introducing the terms near universal and non-overlapping in addition to degenerate. A quick quiz competition is used to generate the number 20 so that the students can learn that there are 20 proteinogenic amino acids in the genetic code. This leads into a challenge, where they have to use their prior knowledge of DNA to calculate the number of different DNA triplets (64) and the mismatch in number is then discussed and related back to the lesson topic. Moving forwards, base substitutions and base deletions are briefly introduced so that they can see how although one substitution can change the primary structure, another will change the codon but not the encoded amino acid. The lesson concludes with a brief look at the non-overlapping nature of the code so that the impact of a base deletion (or insertion) can be understood when covered in greater detail in topic 8. This lesson has been specifically designed to tie in with the other lessons from topic 4.3 on gene mutations, chromosome mutations and meiosis.

This detailed lesson explains how the process of transcription results in the production of mRNA, either directly from DNA in prokaryotes or following splicing in eukaryotes. Both the detailed PowerPoint and accompanying resource have been designed to specifically cover the second part of point 4.2 of the AQA A-level Biology specification but also provides important information that students can use when being introduced to gene expression in topic 8. 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. They will learn that the RNA strand formed at the end of transcription in eukaryotes is a primary transcript called pre-mRNA and then the details of splicing are explained. 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.

A concise lesson presentation (22 slides) and question worksheet, which together focus on the challenge of applying the equations of motion to calculation questions. Students are given this equation on the data sheet in the exam - therefore, this lesson shows them how they will be expected to rearrange in it four ways. For this reason, the start of the lesson revisits the skills involved in rearranging the formula, beginning with simple tasks and building up to those that involve indices as are found in this equation. Once students have practised these skills, they are challenged to answer 4 questions, although 1 is done together with the class to visualise how to set out the working. This lesson has been designed for GCSE students

This clear and concise lesson looks at the calculation of cardiac output as the product of stroke volume and heart rate. This engaging PowerPoint and accompanying resource have both been designed to cover point 7.9 (i) of the Pearson Edexcel A-level Biology A (Salters Nuffield) specification which states that students should be able to calculate cardiac output. The lesson begins by challenging the students to recall that the left ventricle is the heart chamber with the thickest myocardial wall. This leads into the introduction of stroke volume as the volume of blood which is pumped out of the left ventricle each heart beat. A quick quiz game is used to introduce a normative value for the stroke volume and students are encouraged to discuss whether males or females would have higher values and to explain why. A second edition of this quiz reveals a normative value for resting heart rate and this results into the introduction of the equation to calculate cardiac output. A series of questions are used to challenge their ability to apply this equation and percentage change is involved as well. The final part of the lesson looks at the hypertrophy of cardiac muscle and students will look at how this increase in the size of cardiac muscle affects the three factors and will be challenged to explain why with reference to the cardiac cycle that was covered in an earlier topic.

This lesson describes the roles of phosphate, calcium, magnesium and nitrate ions in plants. The PowerPoint and accompanying resources have been designed to cover the content of point 1.6 of the Edexcel A-level biology B specification. The lesson begins by challenging the students to recognise DNA, RNA and phospholipids from three clues, and then they are challenged to recognise that these three biological molecules all contain phosphate ions. Moving forwards, a quick quiz round introduces adenosine triphosphate (ATP) and the students will learn that this is a phosphorylated nucleotide which can be hydrolysed to ADP to release energy. Time is taken to explain how this energy can be coupled to processes within cells such as active transport and examples in plants including the absorption of mineral ions and active loading in the phloem are explored. The rest of the lesson describes the role of magnesium in the production of chlorophyll, nitrates to make DNA and amino acids and calcium ions to form calcium pectate in the middle lamellae. There are multiple understanding checks and also prior knowledge checks, where the students recall of the structure and function of haemoglobin is challenged.

This is a fully-resourced revision lesson that uses a combination of exam questions, understanding checks, quick tasks and quiz competitions to enable students to assess their understanding of the content found within Module 5.1.3 (Neuronal communication) of the OCR A-level Biology A specification. The sub-topics and specification points that are tested within the lesson include: The structure and function of sensory, motor and relay neurones The generation and transmission of nerve impulses in mammals The structure and roles of synapses in neurotransmission Students will be engaged through the numerous quiz rounds such as “Communicate the word” and “Only CONNECT” whilst crucially being able to recognise those areas which require their further attention during general revision or during the lead up to the actual A-level terminal exams

An engaging lesson presentation (33 slides) and associated worksheets that introduces students to classification using the taxonomic levels and teaches them how to name species using the binomial naming system. The students are told about the domain system, as developed by Carl Woese, but then the lesson focuses on showing them the seven levels that come after this. Students are challenged to understand how the levels differ from each other in terms of sharing characteristics. Time is taken to focus on the five kingdoms and links are made to other topics such as prokaryotic cells to test their previous knowledge. Moving forwards, students are shown how the genus and species are used in the binomial naming system before being given lots of opportunities to assess their understanding through questions. This lesson has been written for GCSE students but is suitable for all age ranges
