A fully-resourced lesson which includes a lesson presentation (24 slides) and a worksheet which is differentiated so that students can judge their understanding of the topic of writing half equations for electrolysis and access the work accordingly. The lesson uses worked examples and helpful hints to show the students how to write half equations at both the cathode and anode. Time is taken to remind students about the rules at the electrodes when the electrolyte is in solution so that they can work out the products before writing the equations. This lesson has been designed for GCSE students (14 - 16 years old in the UK) but could be used with older students.

An engaging lesson presentation (64 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 B1 (Cell Biology) of the AQA GCSE Combined Science specification (specification point 4.1). The topics that are tested within the lesson include: Eukaryotes and prokaryotes Animal and plant cells Microscopy Chromosomes The cell cycle including mitosis Stem cells Diffusion Osmosis Active transport Students will be engaged through the numerous activities including quiz rounds like “SPOT the CELL” and “Take the Hotseat” whilst crucially being able to recognise those areas which need further attention

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

This detailed lesson has been planned to cover the 1st part of specification point 6.4.3 of the AQA A-level Biology specification which states that students should be able to describe the detailed structure of the nephron and understand its role in ultrafiltration, selective reabsorption and osmoregulation. The lesson was designed at the same time as the other lessons in this topic on ultrafiltration, selective reabsorption and osmoregulation so that a common theme runs throughout and students can build up their knowledge gradually in order to develop a deep understanding of this organ. Students will come to recognise the renal cortex and renal medulla as the two regions of the kidney and learn the parts of the nephron which are found in each of these regions. Time is taken to look at the vascular supply of this organ and specifically to explain how the renal artery divides into the afferent arterioles which carry blood towards the glomerulus and the efferent arterioles which carry the blood away. The main task of the lesson challenges the students to relate structure to function. Having been introduced to the names of each of the parts of the nephron, they have to use the details of the structures found at these parts to match the function. For example, they have to make the connection between the microvilli in the PCT as a sign that this part is involved in selective reabsorption. This lesson has been designed for students studying on the AQA A-level Biology course

This lesson describes and explains how production is affected by a range of farming practices designed to increase the efficiency of energy transfer. The PowerPoint and accompanying resources are part of the third lesson in a series of 3 which have been designed to cover the detail included in specification point 5.3 of the AQA A-level Biology specification. Over the course of the lesson, a range of tasks which include exam-style questions with displayed mark schemes, guided discussion periods and quick quiz competitions will introduce and consider the following farming practices: raising herbivores to reduce the number of trophic levels in a food chain intensely rearing animals to reduce respiratory losses in human food chains the use of fungicides, insecticides and herbicides the addition of artificial fertilisers The ethical issues raised by these practices are also considered and alternative methods discussed such as the addition of natural predators and the use of organic fertilisers like manure As this is the last lesson in topic 5.3, it has been specifically planned to challenge the students on their knowledge of the previous two lessons and this includes a series of questions linking farming practice to the formula to calculate net production

This lesson describes the main stages of meiosis, focusing on the events which contribute to genetic variation and explains its significance in life cycles. The detailed PowerPoint and accompanying resources have been designed to cover points 2.1.6 (f) & (g) of the OCR A-level Biology A specification and includes description of crossing over, independent assortment, independent segregation and the production of haploid gametes In order to understand how the events of meiosis like crossing over and independent 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 assortment and segregation of chromosomes and chromatids during metaphase I and II and anaphase I and II respectively results in genetically different gametes. The key events of all of the 8 phases are described and there is a focus on key terminology to ensure that students are able to describe genetic structures in the correct context. 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-style questions which challenge the students to apply their knowledge to potentially unfamiliar situations. This lesson has been specifically planned to lead on from the previous two lessons on the cell cycle and the main stages of mitosis and constant references are made throughout to encourage students to make links and also to highlight the differences between the two types of nuclear division

A fully-resourced lesson which uses a step-by-step guide to show students how to write fully balanced symbol equations. The lesson includes an engaging lesson presentation (38 slides) and associated worksheets containing questions which iaredifferentiated. The lesson begins by talking the students through the three steps involved in writing a chemical symbol equation. The first step involves writing in the formula for the elements. Students are introduced to the term, diatomic, and shown the 8 molecules that have to be written as a pair of atoms. Moving forwards, students are shown how to write chemical formulae for ionic compounds. They are reminded of how to use the group of the Periodic Table to work out the ion charge and how this is crucial when writing the formula. They are also shown how to write formulae which include brackets which is necessary when the charged molecules are involved. Finally, students are reminded of the rules of balancing symbol equations. There are progress checks at each stage so that students can assess their understanding and any misconceptions can be be addressed immediately. Time is taken to talk about state symbols, in case the exam question requires these to be included in the equation. The final section of the lesson involves students bringing their new-found skills together to write symbol equations for a range of reactions, including a neutralisation and reversible reaction. This task is differentiated so that students who need a little bit of assistance can still access the work. This lesson has been written for GCSE students (14-16 year olds in the UK)

This lesson describes the structure and functions of the sensory, relay and motor neurones. The engaging PowerPoint and accompanying resources have been designed to cover point 8.1 of the Edexcel International A-level Biology specification but also considers the organisation of the nervous system into the central and peripheral nervous systems and therefore also covers point 8.10. The PowerPoint has been designed to contain a wide range of activities that are interspersed between understanding and prior knowledge checks that allow the students to assess their progress on the current topics as well as challenge their ability to make links to topics from earlier in the modules. Quiz competitions like SAY WHAT YOU SEE are used to introduce key terms in a fun and memorable way. The students will be able to compare these neurones based on their function but time is taken to distinguish between them based on their structural features. The importance of the myelin sheath for the sensory and motor neurones is briefly discussed and students are introduced to key terminology such as saltatory conduction and Schwann cells so they are prepared for the upcoming lesson covering specification point 8.5. The final task involves a comparison between the three neurones to check that the students have understood the structures and functions of the neurones. Throughout the lesson, the organisation of the nervous system is discussed and students are provided with additional knowledge such as the differences between somatic and autonomic motor neurones.

This lesson explains the difference between non-infectious and infectious diseases and names the pathogens that cause examples of the latter. The PowerPoint and accompanying worksheets have been primarily designed to cover points 10.1 (a & b) of the CIE A-level Biology specification but as this is the first lesson in topic 10, links to upcoming topics such as the immune response and vaccinations are introduced. The lesson begins with a challenge where the students have to use descriptions to recognise CHD, HIV and TB as diseases that are commonly referred to by their abbreviations. This leads into a description of the meaning of disease before the students are challenged to use any prior knowledge of this topic to recognise that CHD is an examples of a non-infectious disease whereas HIV and TB are examples of infectious diseases. Specification point 10.1 (a) states that students should know about sickle cell anaemia and lung cancer so the next section of the lesson focuses on the key details of these diseases and when considering the former, their knowledge of gene mutations, protein synthesis and haemoglobin is tested. viruses - HIV/AIDS, influenza, measles, smallpox bacteria - TB, cholera, protoctista - malaria The infectious diseases shown above are covered by the remainder of this lesson and the differing mechanisms of action of these three types of pathogens are discussed and considered throughout. For example, time is taken to describe how HIV uses a glycoprotein to attach to T helper cells whilst toxins released by bacteria damage the host tissue and the Plasmodium parasite is transmitted from one host to another by a vector to cause malaria. The accompanying worksheets contain a range of exam-style questions, including a mathematical calculation, and mark schemes are embedded into the PowerPoint to allow students to immediately assess their understanding.

A fully resourced lesson which includes an informative lesson presentation (34 slides) and differentiated worksheets that show students how to convert between units so they are confident to carry out these conversions when required in Science questions. The conversions which are regularly seen at GCSE are covered as well as some more obscure ones which students have to be aware of. A number of quiz competitions are used throughout the lesson to maintain motivation and to allow the students to check their progress in an engaging way This lesson has been designed for GCSE students but is suitable for KS3

An engaging lesson presentation (73 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 1 (Atomic structure and the Periodic Table) of the AQA GCSE Chemistry specification (specification unit C4.1). The topics that are tested within the lesson include: Mixtures Development of the model of the atom The subatomic particles Electronic structure The periodic table Group 0 Group 1 Group 7 The transition metals Students will be engaged through the numerous activities including quiz rounds like “UNLOCK the safe" whilst crucially being able to recognise those areas which need further attention

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 P6 (Radioactivity) of the Edexcel GCSE Combined Science specification.

A concise lesson presentation (22 slides) that looks at how catalysts affect the rate of a chemical reaction and focuses on the Science behind this topic. The lesson begins with the introduction of the key term and its definition to ensure that students are confident in the use of a catalyst in the correct context. More key terms like “activation energy” are introduced and links made to related Chemistry topics such as endothermic and exothermic reactions. Students are challenged to show how the activation energy will differ in the presence of a catalyst. The rest of the lesson involves a practical and the collection of results so that students can compare their data against the theory which was introduced earlier in the lesson. This lesson has been designed for GCSE students.
