This is an engaging and informative lesson that looks at the wires inside a UK plug and considers their role in terms of the supply of mains electricity. The safety features of the plug, such as the fuse, are also discussed so that students can understand how a particular fuse is chosen. As the cover image shows, the lesson begins by challenging the students to use their knowledge of all three of the Sciences to come up with the three names of the wires. Some students will know that these are the wires in a UK plug but some wont. Key terminology such as three-core cable is used throughout, as well as a running theme with the colours, so that students become accustomed to identifying a particular wire by its plastic insulation. Through a range of tasks which encourage student discovery and educated predictions, the students will learn the functions of each of the wires as well as their potential difference. The fuse is introduced to the students and links are made to the electrical circuits topic by considering the resistance of the wire inside the fuse and challenging them to use the electrical power equation to calculate a current and choose an appropriate fuse for that plug. The aim of the lesson is to get students to absorb information as the lesson progresses in order to eventually label a black and white diagram of the plug. The last part of the lesson looks at two-core cables and then relates this back to the importance of the earth wire in a UK plug. This lesson has been written for GCSE aged students but is suitable for use with younger students who are learning about this topic.

This is a fast-paced lesson that looks at how particle size affects the rate of reaction and challenges the students to carry out a practical to obtain valid results to back up the theory. It is a fully-resourced lesson that consists of an engaging lesson presentation (19 slides) and a calculation worksheet which is differentiated two ways to enable those students who find the maths hard to have a way to access the learning. Students are guided through a method of calculating the surface area and volume of the object and calculating the surface area to volume ratio. Using the answers to their calculations, they will complete a summary passage which explains why having more exposed reacting particles leads to an increased rate of reaction. Students will then carry out a practical where they have to determine which cube of jelly to use to make jelly the fastest in order to test their summary passage is valid. This lesson has been designed for GCSE students but could be used with younger students looking at chemical reactions and investigating the factors that affect the rate.

This lesson describes how respiration produces ATP by substrate-level and oxidative phosphorylation. The PowerPoint and accompanying resources are part of the 1st lesson in a series of 7 lessons which have been designed to cover the detailed content of point 5.2 (RESPIRATION) of the AQA A-level Biology specification. As the first lesson in this sub-topic, it has been specifically planned to act as an introduction to this cellular reaction and provides important details about glycolysis, the Krebs cycle and oxidative phosphorylation that will support the students to make significant progress when these stages are covered during individual lessons. Students met phosphorylation in topic 5.1 when considering the light-dependent reactions of photosynthesis and their knowledge of the production of ATP in this plant cell reaction is called on a lot in this lesson to show the similarities. The students are also tested on their recall of the structure and function of ATP, as covered in topic 1.6, through a spot the errors task. By the end of the lesson, the students will be able to name and describe the different types of phosphorylation and will know that ATP is produced by substrate-level phosphorylation in glycolysis and the Krebs cycle and by oxidative phosphorylation in the final stage of aerobic respiration with the same name.

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 relationship between gross and net primary productivity and plant respiration and explains how to calculate NPP. The PowerPoint and accompanying resources have been designed to cover points 5.10 (i) and (ii) of the Pearson Edexcel A-level Biology A (Salters Nuffield) specification. Due to the fact that the productivity of plants is dependent on photosynthesis, a series of exam-style questions have been written into the lesson which challenge the students to explain how the structure of the leaf as well as the light-dependent and light-independent reactions are linked to GPP. All of the exam questions have displayed mark schemes which are included in the PowerPoint to allow students to immediately assess their understanding. A number of quick quiz competitions as well as guided discussion points are used to introduce the formulae to calculate NPP and N and to recognise the meaning of the components. Once again, this is immediately followed by the opportunity to apply their understanding to selected questions. As well as linking to photosynthesis from earlier in topic 5, this lesson has been specifically planned to challenge students on their understanding of ecosystem terminology from the start of the topic as well as preparing them for the next lesson on the efficiency of biomass and energy transfer

This lesson outlines the need for energy in living organisms, and describes how ATP is formed by phosphorylation in respiration and photosynthesis. The engaging and detailed PowerPoint and accompanying resources have been primarily designed to cover points 12.1 (a, b, c & e) of the CIE A-level Biology specification but can be used as a revision of topics 1, 4 and 6 as the students knowledge of cell structure, membrane transport and ATP is constantly challenged. As this is the first lesson in topic 12 (respiration), it has been specifically planned to act as an introduction to this cellular reaction and provides important details about glycolysis, the Krebs cycle and oxidative phosphorylation that will support the students to make significant progress when these stages are covered during individual lessons. Photophosphorylation is also introduced so students are prepared for the light-dependent reaction of photosynthesis in topic 13. The main focus of the start of the lesson is the demonstration of the need for energy in a variety of reactions that occur in living organisms. Students met ATP in topics 1 and 6, so a spot the errors task is used to check on their recall of the structure and function of this molecule. This will act to remind them that the release of energy from the hydrolysis of ATP can be coupled to energy-driven reactions in the cell such as active transport and a series of exam-style questions are used to challenge them on their knowledge of this form of membrane transport. They will also see how energy is needed for protein synthesis and DNA replication and the maintenance of resting potential, before more questions challenge them to apply their knowledge of cell structure and transport to explain how it is needed during the events at a synapse. The rest of the lesson focuses on the production of ATP by substrate-level, oxidative and photophosphorylation and the students will learn when ATP is formed by each of these reactions and will see how the electron transport chain in the membranes in the mitochondria and chloroplast is involved

This lesson describes the processes that take place during interphase, mitosis and cytokinesis and outlines how checkpoints regulate the cell cycle. The PowerPoint and accompanying resources have been designed to cover points 2.1.6 (a & b) of the OCR A-level Biology specification and prepares the students for the upcoming lessons on the main stages of mitosis and its significance in life cycles The students were introduced to the cell cycle at GCSE so this lesson has been planned to build on that knowledge and to emphasise that the M phase which includes mitosis (nuclear division) only occupies a small part of the cycle. The students will learn that interphase is the main stage and that this is split into three phases, G1, S and G2. A range of tasks which include exam-style questions, guided discussion points and quick quiz competitions are used to introduce key terms and values and to describe the main processes that occur in a very specific order. There is also a focus on the checkpoints, such as the restriction point that occurs before the S phase to ensure that the cell is ready for DNA replication. Extra time is taken to ensure that key terminology is included and understood, such as sister chromatid and centromere, and this focus helps to show how it is possible for genetically identical daughter cells to be formed at the end of the cycle. Important details of mitosis are introduced so students are ready for the next lesson, before the differences in cytokinesis in animal and plant cells are described.

This lesson describes how the empirical formula of a compound can be deduced from the masses of the different parts. The PowerPoint and accompanying resources have been designed to cover points 1.44 & 1.45 of the Edexcel GCSE Chemistry specification and also covers those points in the Chemistry section of the Combined Science course. This lesson uses a step-by-step guide to walk students through the method involved in calculating the empirical formula. Students are given a template to use as they are introduced to the questions and then encouraged to work without it as the lesson progresses. The students are shown how empirical formula questions can be made more difficult and hints are given so that students are able to tackle them and access all of the marks available.

This lesson describes how the limiting reactant controls the mass of the product formed and explains how to deduce the stoichiometry. The PowerPoint and accompanying worksheet, which is differentiated, have been designed to cover points 1.52 & 1.53 of the Edexcel GCSE Chemistry specification and also covers those points in the Chemistry section of the Combined Science course. Step by step guides are used to go through worked examples so students are able to visualise how to set out their work. The lesson begins with a fun analogy involving sausages and potatoes so that students can identify that the potatoes limited the sale of food. Alongside this, students will learn the key term excess. Some time is then taken to ensure that students can spot the limiting reactant and the one in excess in actual chemical reactions and method descriptions. Moving forwards, students will be guided through two calculations that involve limiting reactants - those to calculate the theoretical yield and the other to calculate a balanced symbol equation. Other skills involved in these calculations such as calculating the relative formula mass are recalled and a few examples given to ensure they are confident. The question worksheet has been differentiated two ways so that any students who need extra assistance can still access the learning.
