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)?

This is a detailed and engaging lesson presentation (59 slides) that combines exam questions and progress checks along with quiz competition rounds to enable students to assess their understanding of the specification content within topics C1 - 3 of the OCR GCSE Combined Science Gateway A 9 - 1 as can be assessed in Paper 3. All of the exam questions and progress checks have displayed answers as well as sections where content is recapped so that students can understand how an answer was obtained. The revision rounds in the competition include “The need to BALANCE”, “Number crazy” and “React to the REACTION”. This lesson has been designed for GCSE students.

An engaging lesson presentation (75 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 unit B7(Ecology) of the AQA GCSE Biology specification (specification unit B4.7). The topics that are tested within the lesson include: Communities Abiotic factors Biotic factors Levels of organisation Recycling materials Decomposition Deforestation Global warming Trophic levels Pyramids of biomass Transfer of biomass Students will be engaged through the numerous activities including quiz rounds like “Number CRAZY" whilst crucially being able to recognise those areas which need further attention

A detailed and engaging lesson presentation (52 slides) and accompanying worksheet that looks at competition between organisms and the different types of relationships that exist as a result of this interaction. The lesson begins by looking at the meaning of the biological term, "competition", and then introduces this when it occurs between the same species and different species. Students are challenged to consider the different resources that animals compete for before an activity based competition is used to get them to recognise how this competition can cause changes to the population size. Moving forwards, students will meet the three main types of ecological relationship and look at them in greater detail, with predation being a main focus. There are regular progress checks throughout the lesson (with displayed answers) so that students can assess their understanding. This lesson has been designed for GCSE students but can be used with more-able KS3 students who are looking at ecosystems and the relationships that exist within them

This lesson describes how genetic diversity within, or between species, can be investigated by comparison of characteristics or biological molecules. The PowerPoint and accompanying worksheets are primarily designed to cover the content of point 4.7 of the AQA A-level Biology specification but as this is the last lesson in the topic, it has also been planned to contain a range of questions, tasks and quiz rounds that will challenge the students on their knowledge and understanding of topic 4. Over the course of the lesson, the students will discover that comparisons of measurable or observable characteristics, DNA and mRNA sequences and the primary structure of common proteins can all be used to investigate diversity. Links are continually made to prior learning, such as the existence of convergent evolution as evidence of the need to compare biological molecules as opposed to the simple comparison of phenotypes. The issues associated with a limited genetic diversity are discussed and the interesting biological example of the congenital dysfunctions consistently found in the Sumatran tigers in captivity in Australia and New Zealand is used to demonstrate the problems of a small gene pool. Moving forwards, the study of the 16S ribosomal RNA gene by Carl Woese is introduced and students will learn that this led to the adoption of the three-domain system in 1990. The final part of the lesson describes how the primary structure of proteins like cytochrome c that is involved in respiration and is therefore found in most living organisms can be compared and challenges the students to demonstrate their understanding of protein synthesis when considering the differences between humans and rhesus monkeys.

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 fully-resourced lesson focuses on the events of meiosis which specifically contribute to genetic variation. The detailed PowerPoint and accompanying resources have been designed to cover the 4th and final part of point 4.3 of the AQA A-level Biology specification which states that students should be able to describe how meiosis produces daughter cells that are genetically different from each other. In order to understand how the events of meiosis like crossing over and random assortment and independent segregation can lead to variation, students need to be clear in their understanding that DNA replication in interphase results in homologous chromosomes as pairs of sister chromatids. Therefore the beginning of the lesson focuses on the chromosomes in the parent cell and this first part of the cycle and students will be introduced to non-sister chromatids and the fact that they may contain different alleles which is important for the exchange that occurs during crossing over. Time is taken to go through this event in prophase I in a step by step guide so that the students can recognise that the result can be new combinations of alleles that were not present in the parent cell. Moving forwards, the lesson explores how the independent segregation of chromosomes and chromatids during anaphase I and II results in genetically different gametes. The final part of the lesson looks at the use of a mathematical expression to calculate the possible combinations of alleles in gametes as well as in a zygote following the random fertilisation of haploid gametes. Understanding and prior knowledge checks are interspersed throughout the lesson as well as a series of exam questions which challenge the students to apply their knowledge to potentially unfamiliar situations. Due to the detail of this lesson, it is estimated that this will take about 2 hours of A-level teaching time to deliver

An engaging lesson presentation (61 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 unit B5 (Genes, inheritance and selection) of the OCR Gateway A GCSE Biology specification The topics that are tested within the lesson include: Sexual and asexual reproduction Meiosis Dominant and recessive alleles Genetic crosses The history of genetics Natural selection Classification systems Students will be engaged through the numerous activities including quiz rounds like “Number CRAZY" and “Which Scientist is hidden?” whilst crucially being able to recognise those areas which need further attention

A fun and engaging lesson presentation (33 slides) and associated worksheet that uses exam questions, with fully explained answers, quick tasks and competitions to allow students to assess their understanding of Module 3.1.2 (Transport in Animals). The students will enjoy the lesson whilst being able to recognise which areas of the specification need further attention. Competitions included in the lesson are “SPOT THE ERROR”, “Where’s Lenny” and “Crack the code”

This is an engaging REVISION lesson which uses a range of exam questions, understanding checks, quick tasks and quiz competitions to enable students to assess their understanding of the content within topic 2 (Electricity) of the AQA GCSE Physics (8463) specification. The specification points that are covered in this revision lesson include: Standard circuit diagram symbols Current, resistance and potential difference Resistors Series and parallel circuits Direct and alternating potential difference Mains electricity Power Static charge The students will thoroughly enjoy the range of activities, which include quiz competitions such as “GRAFT over these GRAPHS” where they have to compete to be the 1st to recognise one of the graphs associated with the resistors whilst all the time evaluating and assessing which areas of this topic will need their further attention. This lesson can be used as revision resource at the end of the topic or in the lead up to mocks or the actual GCSE exams

This is a fully-resourced lesson which uses exam-style questions, engaging quiz competitions, quick tasks and discussion points to challenge students on their understanding of the content of topics P1 - P6, that will assessed on PAPER 5. It has been specifically designed for students on the Edexcel 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 thinking and braking distance The 7 recall and apply equations tested in PAPER 5 The units associated with the physical factors challenged in PAPER 5 Recognising the motions represented by different motions on velocity-time graphs Using a velocity-time graph to calculate acceleration Resultant forces Sound waves as longitudinal waves The electromagnetic waves Using significant figures and standard form The relative charges and masses of the particles in an atom Recognising isotopes Using the half-life of radioactive isotopes The development of the atomic model 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 incorporated into the lesson to walk through students through some of the more difficult concepts such as half-life calculations. Due to the extensiveness of this revision lesson, it is estimated that it will take in excess of 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 5 exam.

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 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 worksheets that have been designed to cover point 6.1.2 © of the OCR A-level Biology A specification which states that students should be able to demonstrate and apply their knowledge and understanding of the test to compare the observed and expected results of a genetic cross 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 a fully-resourced revision lesson that uses a combination of exam questions, understanding checks, quick differentiated tasks and quiz competitions to help the students to assess their understanding of the topics found within Topic C2 (Inorganic chemistry) of the Edexcel iGCSE Chemistry specification which has its’ first assessment in 2019. The topics that are tested within the lesson include: Group 1 (alkali metals) Group 7 (halogens) Gases in the atmosphere Reactivity series Extraction and uses of metals Acids, alkalis and titrations Chemical tests Students will be engaged through the numerous quiz rounds whilst crucially being able to recognise those areas which require their further attention during general revision or during the lead up to the actual assessment. The detail of this lesson means that it could be used over a number of lessons at school so that each topic is covered in sufficient depth.

This is a fully-resourced revision lesson that could be used over a series of lessons to help students to revise and assess their knowledge of the content in topics P1 (Matter), P2 (Forces) and P3 (Electricity and magnetism) of the OCR Gateway A GCSE Combined Science specifiction which can be assessed in paper 5. This revision lesson uses a combination of exam questions, understanding checks, quick tasks and quiz competitions to cover the following sub-topics and specification points: Describe how and why the atomic model has changed over time Describe the structure of the atom and the charges of the particles Define the term specific latent heat Conversions from non S.I. units to S.I. units Explain the vector-scalar distinction Recall examples in which objects interact Represent forces as vectors by drawing free-body diagrams Know the definition of Newton’s three laws of motion Define momentum and describe examples of momentum in collisions Recall and apply Newton’s third law Describe the relationship between force and the extension of a spring Calculate the spring constant in linear cases Define mass and weight Recall that current depends upon both potential difference and resistance Recall and apply the relationship between I, R and V Show that Fleming’s left hand rule represents the relative orientations of current, magnetic field and force This lesson contains a big emphasis on the mathematical calculations that will be involved in these exams, and as a result students are challenged to recall the equations and to apply them. Students will be engaged through the numerous quiz rounds whilst crucially being able to recognise those areas which require their further attention during general revision or during the lead up to the actual GCSE terminal exams. A lot of the tasks have been differentiated so that students of all abilities can access the work and be challenged appropriately.

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.

A series of 5 exam questions that challenge students to work out the actual size of a section as seen under a microscope or the magnification. These questions will test their ability to convert between measurements and give answers in micrometers. These questions are suitable for GCSE and A-level students

A concise lesson presentation (20 slides) that looks at how the collision theory is related to the rate of reaction. This is a short lesson that would be taught at the beginning of the topic that looks at the rate of reaction and the factors that affect the rate. Students are challenged with a quick competition that gets them to recognise keywords which are involved in the collision theory. Some time is then taken to focus on "activation energy" and how this is shown on a reaction profile. Finally, students will use their keywords to form a clear definition for the collision theory which includes its link to the rate of reaction so this can be used in the upcoming lessons This lesson has ultimately been designed for GCSE students but can be used with all age groups as an introduction to the topic
