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 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.

The topics that are tested within the lesson include: Relative formula mass Empirical formula Pure and impure substances Separation methods Electronic structures Forming ions Ionic compounds Simple molecules Giant covalent substances Carbon Nanoparticles Students will be engaged through the numerous activities including quiz rounds like “SEPARATE the fact from the fiction” and “Higher or Lower” whilst crucially being able to recognise those areas which need further attention

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

This detailed lesson introduces the 3 main principles of the cell theory and describes how cells are organised into tissues, organs and organ systems. The engaging PowerPoint and accompanying resources have been designed to cover points 2.1 (i) & (ii) of the Edexcel A-level Biology B specification. The cell theory is introduced at the start of the lesson and the 1st principle is immediately discussed to ensure that students are aware that all living organisms are made of cells. This principle is discussed with relation to viruses to enable students to understand that the lack of cell structure in a virus is one of the reasons that they are not considered to be living. The second principle states that the cell is the basic unit of structure and organisation and this leads into the main part of the lesson where specialised cells and their groupings into tissues are considered. Students are challenged to compare an amoeba against a human to get them to focus on the difference in the SA/V ratio. This acts as an introduction into the process of differentiation and a recognition of its importance for multicellular organisms. Students will discover that a zygote is a stem cell which can express all of the genes in its genome and divide by mitosis. Time is then taken to introduce gene expression as this will need to be understood in the later topics of the course. Moving forwards, the lesson uses the process of haematopoiesis from haematopoietic stem cells to demonstrate how the red blood cell and neutrophil differ significantly in structure despite arising from the same cell along the same cell lineage. A series of exam-style questions will not only challenge their knowledge of structure but also their ability to apply this knowledge to unfamiliar situations. These differences in cell structure is further exemplified by the epithelial cells of the respiratory tract and students will understand why the shape and arrangement of these cells differ in the trachea and alveoli in line with function. The link between specialised cells and tissues is made at this point of the lesson with these examples of epithelium and students will also see how tissues are grouped into organs and then into organ systems. The third principle states that cells arise from pre-existing cells and this will be demonstrated later in topic 2 with mitosis and meiosis.

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

An engaging lesson presentation (70 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 C2 (Bonding, structure and properties of matter) of the AQA GCSE Combined Science specification (specification point C5.2) The topics that are tested within the lesson include: Chemical bonds Ionic bonding Ionic compounds Properties of ionic compounds Covalent bonding Metallic bonding Properties of metals and alloys The three states of matter State symbols Structure and bonding of carbon Students will be engaged through the numerous activities including quiz rounds like “The name’s BOND…” whilst crucially being able to recognise those areas which need further attention

This revision lesson contains an engaging powerpoint (45 slides) and associated worksheets that are incorporated into the lesson to challenge and consolidate the learning. The lesson has been designed to contain a wide range of activities so that students remain motivated and engaged whilst they assess their understanding of the content found in Biology topic 3 (Infection and response) of the AQA GCSE Combined Science specification (Trilogy 9-1) The exam questions, differentiated tasks and quiz competitions found within the lesson challenge the following specification topics: Communicable (infectious) diseases Viral diseases Bacterial diseases Fungal diseases Protist diseases The Human defence system Vaccinations Antibiotics Students will be able to use the lesson to identify the areas of the specification that require further attention and this lesson can be used at the end of the topic, in the lead up to the mocks or in the lead up to the actual GCSE exams.

This is a fully-resourced lesson which uses exam-style questions, quiz competitions, quick tasks and discussion points to challenge students on their understanding of topics B1 - B5, that will assessed on PAPER 1. It has been specifically designed for students on the Pearson 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 take place at the local hospital where the students have to visit numerous wards and clinics and the on-site pharmacy so that the following sub-topics can be covered: Cancer as the result of uncontrolled cell division The production of gametes by meiosis Mitosis and the cell cycle Sex determination The difference between communicable and non-communicable diseases The pathogens that spread communicable diseases Identification of communicable diseases Treating bacterial infections with antibiotics Evolution of antibiotic resistance in bacteria Vaccinations Genetic terminology Genetic diagrams Structures involved in a nervous reaction A Reflex arc Risk factors Chemical and physical defences Osmosis and percentage gain and loss Fossils as evidence for human evolution 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 assistance sheets when they are unable to begin a question. Step-by-step guides have also been written into the lesson to walk students through some of the more difficult concepts such as genetic diagrams and evolution by natural selection. 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 duration of the course as well as acting as a final revision before the PAPER 1 exam.

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.

An engaging lesson presentation (48 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 P4 (Atomic structure) of the AQA GCSE Combined Science specification (specification point P6.4). The topics that are tested within the lesson include: The structure of an atom Isotopes Radioactive decay and nuclear radiation Nuclear equations Half-lives Students will be engaged through the numerous activities including quiz rounds like “It’s as easy as ABG” and “ALPHA or BETA” whilst crucially being able to recognise those areas which need further attention

An informative and engaging lesson (46 slides) that looks at the topic of immobilised enzymes and focusses on ensuring that students understand this topic around three main ideas. By the end of the lesson, students will be able to explain why immobilised enzymes are used, describe the different methods by which they are produced and describe some of their uses in biotechnology. Time is taken throughout the lesson to make sure that students understand the disadvantages associated with this process and that they are able to explain the specific limitations of each method. This lesson has been designed for students studying A-level Biology

This fully-resourced lesson describes the meaning of the terms stem cell, pluripotency and totipotency. The PowerPoint and accompanying worksheets have been designed to cover points 3.11 (i) and (ii) of the Pearson Edexcel A-level Biology A (Salters Nuffield) specification and therefore this lesson also contains discussion periods where the topic is the decisions that the scientific community have to make about the use of stem cells in medical therapies. The lesson begins with a knowledge recall of the structure of eukaryotic cells and the students have to use the first letters of each of the four answers to reveal the key term, stem cell. Time is then taken to consider the meaning of cellular differentiation, and this leads into the key idea that not all stem cells are equal when it comes to the number of cell types that they have the potential to differentiate into. A quick quiz round introduces the five degrees of potency, and then the students are challenged to use their understanding of terminology to place totipotency, pluripotency, multipotency, oligopotency and unipotency in the correct places on the potency continuum. Although the latter three do not have to be specifically known based on the content of specification point 3.11 (i), an understanding of their meaning was deemed helpful when planning the lesson as it should assist with the retention of knowledge about totipotency and pluripotency. These two highest degrees of potency are the main focus of the lesson, and key details are emphasised such as the ability of totipotent cells to differentiate into any extra-embroyonic cell, which the pluripotent cells are unable to do. The morula, and inner cell mass and trophoblast of the blastocyst are used to demonstrate these differences in potency. The final part of the lesson discusses the decisions that the scientific community have to make about the use of embryonic stem cells, adult stem cells and also foetal stem cells which allows for a link to chorionic villus sampling from topic 2. There is also a Maths in a Biology context question included in the lesson (when introducing the morula) to ensure that students continue to be prepared for the numerous calculations that they will have to tackle in the terminal exams. This resource has been differentiated two ways to allow students of differing abilities to access the work

This concise lesson covers the content of specification point 5.1.5 (l) of the OCR A-level Biology A specification which states that students should be able to demonstrate and apply an understanding of the action of neuromuscular junctions. Due to a number of similarities between these structures and cholinergic synapses, this lesson uses prior knowledge of these connections between neurones to build a good understanding of the junctions. Students will discover that the events that occur at an axon tip mirror those which happen at the pre-synaptic bulb and this is then developed to look at the differences in terms of the events once the acetylcholine has bound to its receptor sites. There is a focus on the structure of the sarcolemma and time is taken to explain how the action potential is passed from this membrane to the transverse tubules in order to stimulate the release of calcium ions from the sarcoplasmic reticulum. As a result, this lesson ties in nicely with the following lesson on the contraction of skeletal muscle and students will be able to link the binding to troponin in that lesson to the release of these ions from this lesson. Both of the main tasks of the lesson have been differentiated so that students of all abilities can access the work and make progress. This lesson has been designed for those students studying on the OCR A-level Biology course and ties in nicely with the other uploaded lessons on module 5.1.5 (Animal and plant responses)

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”
