This fully-resourced REVISION LESSON has been designed to provide the students with numerous opportunities to assess their understanding of the content of module 5.2.2 (Respiration) of the OCR A-level Biology A specification. The importance of this metabolic reaction is obvious and this is reflected in the volume of questions in the terminal exams which require an in depth knowledge of the stages of both aerobic and anaerobic respiration. The lesson contains a wide range of activities that cover the following points of the specification: Glycolysis as a stage of aerobic and anaerobic respiration The use and production of ATP through respiration Anaerobic respiration in mammalian muscle tissue The stages of aerobic respiration that occur in the mitochondrial matrix Oxidative phosphorylation The use of respirometers Calculating the respiratory quotient value for different respiratory substrates Revision lessons which cover the other sub-modules of module 5 are uploaded and tie in well with this content

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 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 Topic P3 (Particle model of matter) of the AQA Trilogy GCSE Combined Science specification. The sub-topics and specification points that are tested within the lesson include: Density of materials Changes of state Temperature changes in a system and specific heat capacity Changes of heat and specific latent heat 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

This revision lesson has been designed to challenge the students on their use of a range of mathematical skills that could be assessed on the AQA GCSE Combined Science papers. The mathematical element of the AQA GCSE Combined Science course has increased significantly since the specification change and therefore success in those questions which involve the use of maths can prove to be the difference between one grade and another or possibly even more. The engaging PowerPoint and accompanying resources contain a wide range of activities that include exam-style questions with displayed mark schemes and explanations so that students can assess their progress. Other activities include differentiated tasks, class discussion points and quick quiz competitions such as “YOU DO THE MATH” and “FILL THE VOID”. The following mathematical skills (in a scientific context) are covered in this lesson: The use of Avogadro’s constant Rearranging the formula of an equation Calculating the amount in moles using mass and relative formula mass Calculating the relative formula mass for formulae with brackets Using the Periodic Table to calculate the number of sub-atomic particles in atoms Changes to electrons in ions Balancing chemical symbol equations Converting between units Calculating concentration in grams per dm cubed and volumes of solutions Calculating size using the magnification equation Using the mean to estimate the population of a sessile species Calculating percentages to prove the importance of biodiversity Calculating percentage change Calculating the acceleration from a velocity-time graph Recalling and applying the Physics equations Understanding prefixes that determine size Leaving answers to significant figures and using standard form Helpful hints and step-by-step guides are used throughout the lesson to support the students and some of the worksheets are differentiated two ways to provide extra assistance. Due to the detail of this lesson, it is estimated that it will take in excess of 3 hours of GCSE teaching time to cover the tasks and for this reason it can be used over a number of lessons as well as during different times of the year for revision.

This extensive revision lesson challenges students on their knowledge and understanding of the content of topics 5 - 8 of the AQA A-level specification. The PowerPoint and accompanying resources are detailed and engaging and contain a selection of tasks which challenge the following points: Directional, stabilising and disruptive selection Saltatory conduction and other factors affecting conductance speed The structure of a motor neurone Sensory receptors, depolarisation and initiation of an action potential Hardy-Weinberg principle Genetic terminology Codominance and sex-linkage Autosomal linkage Chi-squared test Phosphorylation The stages of aerobic respiration Explaining lower ATP yields in anaerobic respiration Skeletal muscle contraction Structure and function of slow and fast twitch muscle fibres The control of heart rate Electrophoresis and genetic fingerprinting The secondary messenger model The students are tested through a variety of tasks including exam questions, understanding checks, and quiz rounds to maintain engagement. Due to the mathematical content in all A-level exams, there is also a focus on these skills. The answers to all questions are embedded into the PowerPoint so students can use this resource outside of the classroom. The delivery of the whole lesson will likely need at least 2 or 3 hours of contact time so this resource could be used with students in the final weeks building up to their paper 2 exam, or alternatively with students before their mocks on these topics.

This fully-resourced revision lesson consists of an engaging PowerPoint and differentiated resources which together challenge the students on their knowledge of the Key concepts in Physics, which are detailed in topic 1 of the Pearson Edexcel GCSE Physics specification . The content in this topic is particularly important because it will be assessed in both paper 1 and paper 2 of the terminal exams. The lesson has been filled with a wide range of activities which test the following specification points: Recall and use the SI units for physical quantities Recall and use multiples and sub-multiples of units Be able to convert between different units Use significant figures and standard form# To fall in line with the heavy mathematical content of this specification, the main task of the lesson challenges the students to carry out a range of calculations where they have to convert between units and leave their answers in a specific form.

This lesson has been written to act as a revision tool for students at the completion of topic 2.1 of the WJEC GCSE Physics specification or in the lead up to mock or terminal exams. The engaging PowerPoint and accompanying resources have been designed to include a wide range of activities to allow the students to assess their understanding and to recognise any areas which need extra attention. This specification is heavy in mathematical content and so a lot of opportunities are presented for a range of skills to be tested and the PowerPoint guides students through the application of these requirements such as rearranging the formula and converting between units. The following specification points have received a particular focus in this lesson: Motion using speed, velocity and acceleration Speed-time graphs Application of the equations to calculate speed and acceleration Using velocity-time graphs to calculate uniform acceleration and distance travelled Knowledge of the terms reaction time, thinking distance, braking distance and stopping distance The factors which affect these distances A number of quick quiz rounds, such as THE WHOLE DISTANCE, are used to maintain engagement and motivation and to challenge the students on their recall of important points.

This fully-resourced lesson with differentiated resources has been written to prepare students for the range of mathematical-based questions they may face on the two Edexcel GCSE Chemistry papers. The lesson has been designed to contain a wide range of activities which includes 8 quiz competition rounds spread across the duration of the lesson to maintain engagement whilst the students assess their understanding. The mathematical skills covered in this lesson include: Calculating the number of sub-atomic particles in atoms and ions Writing chemical formulae for ionic compounds Identifying isotopes Calculating the relative atomic mass using isotope mass and abundance Using Avogadro’s constant to calculate the number of particles Calculating the relative formula mass Calculating amount in moles using the mass and the relative formula mass Balancing chemical symbol equations Calculating reacting masses Gas calculations using molar volume Calculating concentration of solutions Titration calculations Deducing the empirical formula Calculating energy changes in reactions Most of the resources have been differentiated two ways to allow students of differing abilities to access the work whilst still being challenged. In addition, step by step guides are used to demonstrate how to carry out some of the more difficult calculations such as the harder mole calculations and calculating masses in reactions This lesson could be used with higher ability students on the Edexcel GCSE Combined Science course by taking out the sections which are not applicable.

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.

This lesson revisits the topic of random and systematic errors and also challenges students on other scientific skills such as identifying variables. Students tend to find this topic confusing, so the PowerPoint and accompanying resources have been designed to support them to identify whether an error is random or systematic and then to understand what to do next. The lesson guides the students through a series of real life examples and shows them how to spot each type of error. There is a considerable mathematical element to this lesson, including the calculation of means or missing values in a table. The lesson concludes with a series of exam-style questions where the students have to apply their understanding of identifying errors, variables and calculating means.

A wide range of activities have been written into this resource to maintain motivation and these tasks include exam questions (with answers), understanding checks, differentiated tasks and quiz competitions. The lesson has been designed to cover as much of the content as possible, but the following sub-topics have been given particular attention: Genetic terminology Using genetic diagrams to calculate phenotypic ratios and percentages for the inheritance of a single gene Applying the Hardy-Weinberg principle Sex-linkage Codominance, multiple alleles and interpreting genetic trees Types of variation Ecological terminology Dihybrid inheritance Using the chi-squared test to determine significance Epistasis Succession Sampling to estimate populations and consider distribution The mathematic elements of this topic and specification are challenged throughout the resource and useful hints given to enable the students to pick up vital marks from questions on this topic. Due to the size of this resource, teachers may choose to use it over the course of a number of lessons and it is suitable for use at the end of topic 7, in the lead up to the mocks or in the lead up to the actual A-level exams.

This detailed and engaging lesson supports students with their revision in the build up to their UNIT 1 mocks or final assessment. The wide range of tasks and activities will challenge them on their knowledge of Molecules, Diet, Transport and Health (topics 1 and 2) of the Edexcel International A-level biology specification, allowing them to identify any areas which require further attention before the examinations. Included in the range of tasks are exam-style questions and understanding checks and all answers are embedded into the PowerPoint. There are quiz rounds to maintain engagement and to encourage healthy competition, as well as guided discussion periods to provide opportunities for students to support each other. The following content is directly covered by this revision lesson: The nature of the genetic code Globular and fibrous proteins Protein structure Haemoglobin and the affinity for oxygen The role of the heart valves in the cardiac cycle The course of events that lead to atherosclerosis Passive and active transport DNA replication The structure and function of starch Genetic terminology Codominance Sex-linked diseases Many of the tasks have been differentiated to maintain challenge whilst providing access to all. This is an extensive lesson with many tasks so it is estimated that it will take over 3 hours of teaching time if covered in full, but teachers may choose to use sections to focus on a specific topic.

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 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

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

This is a fully-resourced lesson that looks at the functional and structural differences between the transport tissues in a plant, the xylem and phloem. The lesson includes an engaging lesson presentation (41 slides), which includes numerous student-led tasks, progress checks and quick competitions and two question worksheets, one of which is a differentiated version to enable those students who are finding this topic difficult to still be able to access the learning. The lesson begins with the introduction of the two tissues as well as a brief introduction to the substances which they each carry. The next part of the lesson focuses on the xylem cells and the resulting xylem vessel, and key terms such as lignin are brought into the lesson so that students can understand how these cells are waterproofed, which causes them to decay and form hollow tubes. Having met a lot of information, students are challenged to act like an examiner to form a table based question to compare the xylem against the phloem where they have to come up with features which could be compared against. This table will form the backbone of the lesson and students will use it later in the lesson when they have to write summary passages about each of the tissues. Moving forwards, a quick competition is used to enable the students to meet the names of the cells that form the phloem tissue, the sieve tube elements and the companion cells. Students will see how they are involved in the functioning of the phloem and questions are posed which relate to other topics such as the involvement of mitochondria wherever active transport occurs. Progress checks like this are found at regular intervals throughout the lesson so that students can constantly assess their understanding. This lesson has been designed for GCSE students. If you are looking to teach about these tissues but to a higher standard, you could use my uploaded alternative called Xylem and Phloem (A-level)
