A detailed lesson which uses a step by step guide to take students through titration calculations. The lesson begins by looking at jey terminology such as the “rough” and “titre”, which are discussed and explained so that there isnt any confusion. Time is taken to go over key steps in the method, such as using the molar ratio from the equation, so that students are prepared for these if they encounter in an assessment. This lesson has been designed primarily for GCSE students (14 - 16 year olds in the UK) but is suitable for older students covering this at A-level

A fully-resourced lesson which looks at the chemical reaction that is aerobic respiration and ensures that students can apply their knowledge to application questions which challenge them to make links to related topics. The lesson includes a practical-based lesson presentation (19 slides) and associated worksheets containing differentiated questions. The aim of the beginning of the lesson involves getting students to understand the term, concentration, so that they are able to use it accurately in their descriptions. This is a term which is commonly wrongly used by students. Moving forwards, students will carry out a practical to collect valid results so that they can apply their knowledge of concentration to explain a trend. Certain practical skills are challenged during the lesson such as the drawing of a results table to display the results. A worksheet containing questions on the practical is differentiated so that students who need assistance are still able to access the learning. This lesson has been designed for GCSE students but can be used with KS3 students who are learning about chemical reactions.

An engaging lesson presentation (39 slides) with associated differentiated worksheets that looks at they key differences between pure and impure substances and briefly explores how a mixture like an alloy can still be very useful. The lesson begins by challenging the students to recognise 4 diagrams of pure substances from a selection of 5. This will lead students to the definition of pure (in Science) which is likely to be different to what they have encountered in everyday language. The next task gets the students to draw a graph showing the melting and boiling points of pure water. This will enable them to compare the melting point against that of an impure substance and therefore recognise that this difference can be used as point to decide on purity. An example of gritting is used to explain how this change in melting point can be utilised and then the students are challenged to apply this new-found knowledge to the situation of adding salt to boiling water when making pasta. The remainder of the lesson focuses on some famous mixtures. Beginning with air, students will be able to visualise how this mixture is made of a number of gases, each with different boiling points which allows them to be separated by fractional distillation. Alloys are briefly explored so that students know why these mixtures are used for certain functions over pure metals and the summary passage for this task has been differentiated two ways so that all can access the work. Progress checks have been written into the lesson at regular intervals so that students can check their understanding and a range of quick quiz competitions are used to maintain engagement whilst introducing new terms in a fun manner. If you want to look into alloys in greater detail, then this lesson could be combined with the one named “alloys” which is also uploaded.

This lesson describes the differences between the primary and secondary responses and describes how the structure of antibodies is related to function. The PowerPoint and accompanying resources have been designed to cover specification points 4.1.1 (g), (h) and (i) as detailed in the OCR A-level Biology A specification and emphasises the importance of memory cells. As memory B cells differentiate into plasma cells that produce antibodies when a specific antigen is re-encountered, it was decided to link the immune responses and antibodies together in one lesson. The lesson begins by checking on the students incoming knowledge to ensure that they recognise that B cells differentiate into plasma cells and memory cells. This was introduced in a previous lesson on the specific immune response and students must be confident in their understanding if the development of immunity is to be understood. A couple of quick quiz competitions are then used to introduce key terms so that the structure of antibodies in terms of polypeptide chains, variable and constant regions and hinge regions are met. Time is taken to focus on the variable region and to explain how the specificity of this for a particular antigen allows neutralisation and agglutination to take place. The remainder of the lesson focuses on the differences between the primary and secondary immune responses and a series of exam-style questions will enable students to understand that the quicker production of a greater concentration of these antibodies in the secondary response is due to the retention of memory cells.

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

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.

This is a concise REVISION lesson that contains an engaging powerpoint (34 slides) and associated worksheets. The lesson uses a range of activities which include exam questions (with displayed answers), differentiated tasks and quiz competitions to engage students whilst they assess their knowledge of the content that is found within topic P7 (Magnetism and electromagnetism) of the AQA Trilogy 9-1 GCSE Combined Science specification. Generally, this is a topic which isn’t particularly well understood by students but is regularly assessed through questions in the GCSE exams and so time has been taken to design the lesson so that the key points are covered and common misconceptions addressed. The following sub-topics in the specification are covered in this lesson: Poles of a magnet Magnetic fields Electromagnetism Fleming’s left hand rule Electric motors This lesson can be used throughout the duration of the GCSE course, as an end of topic revision lesson or as a lesson in the lead up to mocks or the actual GCSE exams
