The AQA specification states that a minimum of 10% of the marks across the 3 assessment papers will require the use of mathematical skills. This revision lesson has been designed to include a wide range of activities that challenge the students on these exact skills because success in the maths in biology questions can prove the difference between one grade and the next! Step-by-step guides are used to walk students through the application of a number of the formulae and then exam-style questions with clear mark schemes (which are included in the PowerPoint) will allow them to assess their progress. Other activities include differentiated tasks, group discussions and quick quiz competitions such as “FROM NUMBERS 2 LETTERS” and “YOU DO THE MATH”. The lesson has been written to cover as much of the mathematical requirements section of the specification as possible but the following have been given particular attention: Hardy-Weinberg equation Chi-squared test Calculating size Converting between quantitative units Standard deviation Estimating populations of sessile and motile species Percentages and percentage change Cardiac output Geometry Due to the detail and extensiveness of this lesson, it is estimated that it will take in excess of 2/3 hours of A-level teaching time to work through the activities and it can be used throughout the duration of the course

This resource has been designed to motivate students whilst they evaluate their understanding of the content in modules 1, 2, 3 and 5 of the OCR A-level Biology A specification which can be assessed in PAPER 1 (Biological processes). The resource includes a detailed and engaging Powerpoint (149 slides) and is fully-resourced with differentiated worksheets that challenge the students on a wide range of topics. The resource has been written to include different types of activities such as exam questions with explained answers, understanding checks and quiz competitions. The aim was to cover as much of the specification content as possible but the following topics have been given particular attention: Monosaccharides, disaccharides and polysaccharides Glycogen and starch as stores and providers of energy The homeostatic control of blood glucose concentration Osmoregulation Lipids Ultrafiltration and selective reabsorption Diabetes mellitus Voluntary and involuntary muscle The autonomic control of heart rate The organisation of the nervous system The gross structure of the human heart Haemoglobin and the Bohr shift Bonding The ultrastructure of plant cells Cyclic vs non-cyclic photophosphorylation Oxidative phosphorylation Anaerobic respiration in eukaryotes Helpful hints and tips are given throughout the resource to help students to structure their answers. This resource can be used in the lead up to the actual Paper 1 exam or earlier in the course when a particular area of modules 1, 2, 3 or 5 is being studied. If you are happy with this resource, why not look at the one which has been designed for Paper 2 (Biological diversity)?

A detailed lesson presentation (37 slides) and associated worksheets that looks at the different pieces of evidence that scientists use to support evolution and discusses how these support the theory. The lesson begins by challenging students to decide which piece of evidence is the key piece in supporting evolution (fossils). Students will then have to arrange a number of statements to describe how a fossil is formed. Students are introduced to the fossil record and questions are used to check that they understand where the oldest fossils would be found. Moving forwards, students are given three pieces of evidence that would be observed in the fossil record and they are challenged to explain how each of these supports the theory of evolution. Quick competitions are then used to get the students to see some extinct organisms in the Dodo and Woolly Mammoth and again they are questioned on how extinct animals support the theory of evolution. Further evidence in rapid changes in species and molecular comparison is discussed. There are regular progress checks throughout the lesson so that students can assess their understanding and there is a set homework included.

This REVISION resource has been written with the aim of motivating the students whilst they are challenged on their knowledge of the content in Chemistry TOPIC 2 (States of matter and mixtures) of the Edexcel GCSE Combined Science specification. The resource contains an engaging and detailed PowerPoint (65 slides) and accompanying worksheets, most of which are differentiated to allow a range of abilities to access the work. The wide range of activities, which include exam questions and quiz competitions, have been designed to cover as much of topic 2 as possible but the following sub-topics have been given a particular focus: Pure substances in Science Using melting and boiling points to distinguish between pure and impure Separating mixtures using simple and fractional distillation Determining a state of matter using data Physical changes Crystallisation The mobile and stationary phases of paper chromatography Calculating the retention factor The treatment of water to make potable water This resource is suitable for use at the end of topic 2, in the lead up to mocks or in the preparation for the final GCSE exams.

This detailed lesson describes the absorption of water, the movement through the root and the role of the endodermis. Both the PowerPoint and accompanying resource have been designed to cover specification points (j, k & l) in topic 3 of AS unit 2 of the WJEC A-level Biology specification and includes descriptions of the apoplast, symplast and vacuolar pathways and the Casparian strip. The lesson begins by looking at the specialised features of the root hair cell so that students can understand how these epidermal cells absorb water and mineral ions from the soil. Moving forwards, students are introduced to key terminology such as epidermis and root cortex before time is taken to look at the different pathways that water and minerals use to transverse across the cortex. Discussion points are included throughout the lesson to encourage the students to think about each topic in depth and challenges them to think about important questions such as why the apoplast pathway is needed for the water carrying the ions. The main part of the lesson focuses on the role of the endodermis in the transport of the water and ions into the xylem. Students will be introduced to the Casparian strip and will learn how this layer of cells blocks the apoplast pathway. A step by step method using class questions and considered answers is used to guide them through the different steps and to support them when writing the detailed description. This lesson has been written to tie in with the next lesson on the pathways and mechanisms by which water and mineral ions are transported to the leaves.

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

This lesson describes the actions of the sympathetic and parasympathetic divisions of the ANS. The PowerPoint and accompanying resources are part of the 8th lesson in a series of 17 lessons that cover the details of the brain and neuropsychology topic of the AQA GCSE Psychology specification. The students were introduced to the autonomic nervous system (ANS) in the 1st lesson in this topic, so this lesson has been designed to deepen and further their understanding of the actions of this system. Students will come to understand that the sympathetic division is most active during times of stress whilst the parasympathetic division is most active during times of sleep and relaxation. Through a series of tasks including a fun quiz round, they will discover the actions of the two divisions and then be challenged to apply their understanding. This topic of the brain and neuropsychology has proved particularly difficult for the students in recent years, so I have taken time to analyse the lesson sequencing. There’s a lot of content to absorb and to understand before moving onto the next part, so I’ve tried to ensure that cross topics links and prior knowledge checks run throughout the lessons. I have organised the lessons to run through the biology content first before moving onto the psychology parts as shown by the 17 lessons below: #1 Organisation of the nervous system #2 The structure and function of the cerebral lobes #3 The cerebellum #4 The structure and function of the sensory and motor neurones #5 The relay neurones #6 Synaptic transmission #7 Excitation and inhibition at the synapse #8 The autonomic nervous system #9 The fight or flight response #10 The somatic nervous system #11 James-Lange theory of emotion #12 James-Lange theory of emotion part 2 #13 Penfield’s study of the interpretative index #14 Hebb’s theory of learning and neuronal growth #15 An introduction to neuropsychology #16 Brain scanning techniques #17 Tulving’s gold memory study

This engaging lesson presentation (51 slides) and associated worksheets uses exam questions with displayed mark schemes, quick tasks and quiz competitions to enable students to assess their understanding of the topics found within module B6 of the OCR Gateway A Combined Science specification. The topics which are specifically tested within the lesson include: Genetic engineering, Health and disease, Spread of communicable diseases and preventing the spread, Non-communicable diseases, Treating CVD and Modern advances in medicine Students will enjoy the competitions such as "Is this ENGINEERED correctly" and "COMMUNICATE the word" whilst crucially being able to recognise those areas which need their further attention

An engaging lesson presentation (42 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 TOPIC 6 (The rate and extent of chemical change) of the AQA GCSE Chemistry specification (specification point C4.6) The topics that are tested within the lesson include: Calculating rates of reactions Factors that affect the rate of a reaction Collision theory Reversible reactions Equilibrium Changing the equilibrium position Students will be engaged through the numerous activities including quiz rounds like “Don’t get iRATE” and “Under PRESSURE” whilst crucially being able to recognise those areas which need further attention

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

An engaging lesson presentation (16 slides) which looks at the surface area to volume ratio and ensures that students can explain why this factor is so important to the organisation of living organisms. This is a topic which is generally poorly misunderstood by students and therefore time has been taken to design an engaging lesson which highlights the key points in order to encourage greater understanding. The lesson begins by showing students the dimensions of a cube and two answers and challenges them to work out what the questions were that produced these answers. Students are shown how to calculate the surface area and the volume of an object before it is explained how this can then be turned into a ratio. Time is taken at this point to ensure that students can apply this new-found knowledge as they have to work out which of the three organisms in the “SA: V OLYMPICS” would stand aloft the podium. Students are given the opportunity to draw conclusions from this task so that they can recognise that the larger the organism, the lower the surface area to volume ratio. The lesson finishes by explaining how larger organisms, like humans, have adapted in order to increase the surface area at important exchange surfaces in their bodies. There are regular progress checks throughout the lesson to allow the students to check on their understanding. This lesson has been written for GCSE students but is perfectly suitable for A-level students who want to look at this topic from a basic level

A detailed lesson presentation (25 slides) that introduces students to the difficult topic of specific heat capacity. Students are guided through the equation for energy transferred and shown how to rearrange the equation, so they are able to tackle the question, no matter the subject of the question. There are regular opportunities for students to apply their new found knowledge to questions and to assess themselves against the answers. Quick games and competitions are also used to maintain engagement. If you choose to download this lesson, it would be much appreciated if you would take just a few seconds to write a review so I can improve my practice and other teachers can see if this resource is right for them. Thank you in advance.
