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 3 (Chemical changes) of the Edexcel GCSE Chemistry specification. The specification points that are covered in this revision lesson include: Recall that acids in solution are sources of hydrogen ions and alkalis in solution are sources of hydroxide ions Recall that the higher the concentration of hydrogen ions in an acidic solution, the lower the pH; and the higher the concentration of hydroxide ions in an alkaline solution, the higher the pH Recall that as hydrogen ion concentration in a solution increases by a factor of 10, the pH of the solution decreases by 1 Recall that a base is any substance that reacts with an acid to form a salt and water only Recall that alkalis are soluble bases Explain the general reactions of aqueous solutions of acids with metals, metal oxides, metal hydroxides and metal carbonates to produce salts Describe the chemical test for hydrogen and carbon dioxide Describe a neutralisation reaction as a reaction between an acid and a base Explain an acid-alkali neutralisation as a reaction in which hydrogen ions (H+) from the acid react with hydroxide ions (OH–) from the alkali to form water Explain how a soluble salts is prepared from an acid and an insoluble reactant Explain how soluble salts are prepared from an acid and a soluble reactant Recall that electrolytes are ionic compounds in the molten state or dissolved in water Explain the movement of ions during electrolysis Explain the formation of the products in electrolysis Write half equations for reactions occurring at the anode and cathode in electrolysis Explain oxidation and reduction in terms of loss or gain of electrons The students will thoroughly enjoy the range of activities, which includes quiz competitions like “From NUMBERS 2 LETTERS” where they compete to be the 1st to get the abbreviation Oil Rig whilst crucially being able to recognise the areas of this topic which 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 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 7 (Magnetism and electromagnetism) of the AQA GCSE Physics (8463) specification. The specification points that are covered in this revision lesson include: Poles of a magnet Electromagnetism Fleming’s left hand rule Electric motors Loudspeakers Transformers Of all of the Physics topics, this one tends to be one of the least well understood. Therefore, time has been taken to not only make this an engaging revision lesson but to go into detail on some of the topics which are commonly assessed in the exams. 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 has been designed to cover specification point 6.4.1 of the AQA A-level Biology specification. The resource contains a detailed and engaging PowerPoint and accompanying worksheets which ensure that students can apply their understanding of the principles of homeostasis to include the regulation by negative feedback. As homeostasis is a topic met at GCSE, this lesson has been written to build on this knowledge as well as to check on their prior knowledge of earlier A-level topics such as osmosis when considering blood water potential and the use of glucose as a respiratory substrate. Discussion points are written into the lesson at regular intervals to encourage the students to consider why a particular process or method takes place and understanding checks allow them to assess their progress. Students will recall how body temperature, blood water potential and blood glucose concentration are maintained within restricted limits and the importance of these systems are looked into in detail. Time is taken to consider the importance of maintaining these aspects, specifically with relation to the activity of enzymes. As such, students will also discuss how the pH of the blood is maintained. The key components of the control system are recalled and then time is taken to focus on the cell signalling that occurs between the coordination centre and the effectors. Students will learn to associate the response with either the use of the neuronal or hormonal system. The final part of the lesson looks at the importance of negative feedback in reversing the change in order to bring the aspect back to the optimum and the added degree of control which this provides. Positive feedback is also briefly mentioned at the end. This lesson has been written for A-level students who are studying the AQA A-level Biology course and because of the detail of this specification point, it is likely that this resource will cover 2 or more lessons in order for deep understanding to be developed.

This detailed lesson looks at the structure and function of the motor neurones that form the autonomic nervous system and is responsible for automatic responses. The engaging PowerPoint and accompanying resource have both been designed to cover the second part of point 5.1.5 (g) 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 functional organisation of the motor system into somatic and autonomic systems. Students will discover that this system is further divided into sympathetic and parasympathetic systems to control different aspects of a particular involuntary response. The lesson begins with a focus on the types of effectors that will be connected to the CNS by autonomic motor neurones. Students will learn that effectors which are not under voluntary control such as cardiac muscle, smooth muscle and glands will be innervated by these neurones. Moving forwards, a quick quiz competition is used to introduced ganglia as a structure which connects the two or more neurones involved in the cell signalling between the CNS and the effector. This leads into the discovery of the two divisions and students will begin to recognise the differences between the sympathetic and parasympathetic systems based on function but also structure. The remainder of the lesson looks at the differing effects of these two systems. This lesson has been written to tie in with the lesson on the organisation of the mammalian nervous system which covers the first part of specification point 5.1.5 (g)

This fully-resourced lesson explores how projects to sequence the genomes of both simple and complex organisms can be used. Both the detailed PowerPoint and accompanying resources have been designed to cover the content of point 8.3 of the AQA A-level Biology specification. The start of the lesson describes each step of Sanger’s chain termination method and demonstrates how this method has paved the way for other projects. The use of the modified nucleotides are explained and links are made to the topic 4 and 2 where protein synthesis and DNA replication were first introduced. Students will learn how the radioactively-labelled nucleotide at the end of each fragment allows the next base to be determined. Key processes like gel electrophoresis are introduced and details provided to support the students when this is encountered in greater detail in 8.4.3. Moving forwards, the applications of sequencing in simple organisms like viruses and bacteria are explored and the students are challenged on their prior knowledge of bacterial pathogenesis and current understanding of sequencing through a series of exam-style questions. The final part of the lesson looks at the difficulties of translating genome knowledge into proteome knowledge and considers the development of automated methods. Due to the detail and extensiveness of this lesson, it is estimated that it will take in excess of 2 hours of allocated A-level teaching time to cover all of the points which have been written into the various tasks

This fully-resourced lesson describes the sliding filament model of muscular contraction and has been designed to cover the 4th part of point E2 in UNIT 2 of the Pearson BTEC Level 3 National Diploma in Sport and Exercise Science specification. The wide range of activities included in the lesson will engage and motivate the students whilst the understanding checks will allow them to assess their progress. The lesson begins by getting them to reveal the prefix myo so that they can recognise that myology is the study of muscles. This leads into the next task, where they have to identify two further terms beginning with myo and are the names of structures involved in the arrangement of skeletal muscle. Key terminology is used throughout the lesson so that students feel comfortable when they encounter this in questions. Students were introduced to the sarcomere and the bands and zones that are found within a myofibril in a previous lesson and they are challenged to discuss how the sarcomere can narrow but the lengths of the myofilaments remain the same. The main task of the lesson involves the formation of a bullet point description of the sliding filament model where one event is the trigger for the next. Time is taken during this section to focus on the involvement of calcium ions and ATP. The final part of the lesson involves students having to apply their knowledge by describing the effect on muscle contraction when a part of a structure is unable to function correctly.

This engaging lesson describes how the structure of the phloem enables this vascular tissue to transport organic substances in plants. Both the detailed PowerPoint and accompanying resource have been designed to cover the 3rd part of point 3.4.2 (Mass transport in plants) of the AQA A-level Biology specification. Comparative questions between the xylem and phloem are very common so the lesson begins by challenging the students to use their prior knowledge to complete the xylem column of a table with details including the presence of lignin and bordered pits and specific substances which are transported in this tissue. This has been written into the lesson to encourage the students to start to think about how the structure and function of the phloem may compare. 3 quiz rounds have been included in the lesson to maintain motivation and to introduce key terms. The first of these rounds will challenge the students to be the first to recognise descriptions of sucrose and amino acids as they learn that these are the two most common assimilate, which are the substances transported by the phloem. The focus of this lesson is the relationship between structure and function and all descriptions have these two parts highlighted to support the students to recognise the link. Moving forwards, students will be introduced to the sieve tube elements and the companion cells and time is taken to consider why the structure of these cells are so different. Current understanding checks are interspersed throughout the lesson to ensure that any misconceptions can be quickly addressed. The plasmodesmata is described to allow students to understand how assimilates move from the companion cells to the sieve tube elements as this will be particularly important for the next lesson on translocation. The final task of the lesson challenges the students to write a detailed passage about the structure and function of the phloem, incorporating all of the information that they have absorbed throughout the course of the lesson.

An engaging lesson presentation (41 slides) and accompanying worksheet that looks at the different causes of variation and the different types of variation. The lesson begins by challenging the students to pick out a set of siblings from a series of pictures and then getting them to explain scientifically why they made the decision that they did. Moving forwards, students will recognise that one cause of variation is genes. Students are shown a pair of identical twins and asked to explain why they look different despite their identical genes so that they can understand that the environment also affects variation. Students will also meet discontinuous and continuous variation and will understand how this data should be represented. There are progress checks throughout the lesson to allow the students to assess their understanding. This lesson has been designed for KS3 and GCSE students.

An informative lesson presentation (37 slides) and accompanying worksheets that guides students through the different methods that can be used to rearrange formulae as they will be required to do in the Science exams. The lessons shows them how to use traditional Maths methods involving inverse operations and also equation triangles to come to the same result. These are constantly linked to actual examples and questions to show them how this has to be applied. There are regular progress checks, with explained answers, so that students can assess their understanding.

This lesson presentation looks at the carboxylic acids and focuses on the names, displayed formula, chemical formulae and reactions of this homologous series. The lesson begins with a bit of fun which gets enables the students to recognise that the functional group is COOH. A step by step guide is used to show the students how to draw the displayed formula for ethanoic acid, using the functional group before they apply their knowledge to draw the remaining acids in the first four. This series are connected by a general formula and students are shown how it is worked out for the alkanes and the alkenes so that students can work it out for the acids. Moving forwards, the reactions of these acids is shown and related to the reactions of acids that was previously learnt. Students will recall how to write the name of the salt and the balanced symbol equation. This lesson has been written for GCSE students

This lesson has been written with the aim of engaging students in the topic of simple and giant covalent molecules, as this is a topic which is often considered to be boring or is brushed over. A variety of tasks have been used to maintain the interest whilst ensuring that they key details and Science are known and understood. The lesson begins with a quick recap task where students have to recognise a covalent bond from a description and fill the missing part. Moving forwards, they are introduced to the fact that covalent molecules can be simple or giant. They are then presented with a table showing some properties of covalent molecules and having to group them as simple or giant in the short space of time that the table remains displayed on the board. This task challenges their observational skills, something which will again be tested later in the lesson as they study the structure of graphite and diamond. Time is taken to ensure that key details such as the strong covalent bonds in both sets of molecules is understood and that it is the weak intermolecular forces which are actually responsible for the low melting and boiling points. The last part of the lesson introduces diamond and graphite as allotropes of carbon and students will briefly learn why one of these conducts electricity whilst the other doesn’t. If you want a lesson about these allotropes in more detail, then please look for “Diamond and Graphite”. Progress checks have been written into the lesson at regular intervals so that students are constantly assessing their understanding and so misconceptions are quickly identified. This lesson has been written for GCSE students (14 - 16 years of age in the UK)

A really engaging and detailed lesson presentation (44 slides) and associated differentiated worksheets that looks at communicable diseases in plants and challenges students to diagnose these diseases in plants. During the lesson the students will take on the role of the “Treeage” (triage) nurse and have to direct each plant to the correct ward in the “CASUALTREE” according to the pathogen which has infected them. They will also have to explain how the symptoms which they have identified were caused and explain the future for this plant, during their time as the “Tree surgeon”. The three diseases included in the lesson are tobacco mosaic virus, crown gall disease and powdery mildew disease. There are regular progress checks throughout the lesson so that students can assess their understanding and there is a set homework included as part of the lesson. This lesson has been designed for GCSE students but is also suitable for A-level students looking at the communicable diseases topic

A fully resourced lesson that includes a lesson presentation (31 slides) and a related newspaper story to allow the students to compare the structure and properties of two allotropes of carbon, diamond and graphite. Students are guided through the structures and then challenged to work out how this relates to their respective properties. Time is taken to focus on the comparison between the two in terms of their ability to conduct electricity. A step by step answer is used to explain why diamond cannot conduct electricity so that students can use this when forming their answer for graphite. This lesson has been designed primarily for GCSE students (14 - 16 year olds) where questions comparing these two substances are common but it is suitable for use with younger students too.

A fast-paced lesson which includes an informative lesson presentation (20 slides) and a question worksheet. Together these resources guide GCSE students through the calculation questions that they can encounter on the topic of the conservation of momentum. The lesson begins by introducing the law of the conservation of momentum and reminding students of the equation which links momentum, mass and velocity that they are expected to recall for the GCSE exam. Time is taken to inform them of the two types of question which tend to arise on this topic - those where the masses lock together during the event and those where they remain as separate masses. Students are guided through both of these types of questions with worked examples to enable them to visualise how to begin and set out their workings. Key mathematical skills are involved such as rearranging the formula so this is also shown. Students are given the opportunity to apply these skills to a series of questions on the worksheet and the mark schemes are displayed so they can assess once completed.

This lesson describes the active loading of assimilates like sucrose at the source and the translocation along the phloem to the sink. Both the detailed PowerPoint and accompanying resources have been designed to cover point 3.1.3 (f) of the OCR A-level Biology A specification. The lesson begins by challenging the students to recognise the key term translocation when it is partially revealed and then the rest of the lesson focuses on getting them to understand how this process involves the mass flow of assimilates down the hydrostatic pressure gradient from the source to the sink. It has been written to tie in with 3.1.3 (b) where the structure of the phloem tissue was initially introduced and the students are continually challenged on this prior knowledge. A step-by-step guide is used to describe how sucrose is loaded into the phloem at the source by the companion cells. Time is taken to discuss key details such as the proton pumping to create the proton gradient and the subsequent movement back into the cells by facilitated diffusion using co-transporter proteins. Students will learn that the hydrostatic pressure at the source is high, due to the presence of the water and sucrose as cell sap, and that this difference when compared to the lower pressure at the sink leads to the movement along the phloem. A number of quick quiz rounds are included in the lesson to maintain engagement and to introduce key terms and the lesson concludes with a game of SOURCE or SINK as students have to identify whether a particular plant structure is one or the other (or both)

This fully-resourced lesson has been designed to cover the content in point 3.17 (Inheritance of ABO blood groups) as detailed in the Edexcel GCSE Biology specification. As specified in this point, students will learn how this inheritance demonstrates both codominance and multiple alleles. A potentially difficult topic, time has been taken to include guidance sections where students are walked through the interpretation of the different genotypes to find out the phenotypes as well as constructing genetic diagrams and calculating blood groups from pedigree trees. There is a real focus on genetic terminology such as allele, locus, genotype and phenotype so that the understanding is deep and students can use this if they choose to further their studies at A-level. This lesson has been designed for GCSE-aged students studying the Edexcel GCSE Biology course but is also suitable for older students who are learning about codominance and multiple alleles at A-level
