This is an engaging revision lesson which uses a range of exam questions, understanding checks, quick differentiated tasks and quiz competitions to allow students to assess their knowledge of the topic of moles and related topics as covered in the GCSE Chemistry and GCSE Combined Science courses. An understanding of moles and their associated calculations is critical for the success of a student in these two courses. The following topics are covered in this revision lesson: Avogadro’s law and constant Mole calculations involving Avogadro’s constant Mole calculations involving the formula, moles = mass x molar mass Mole calculations involving the constant and the formula Moles in balanced symbol equations and identifying molar ratios of reactants or reactants to products Calculating masses in reactions Gas calculations (molar volume) Concentration of solutions (in mol per decimetre cubed) Students will be engaged through the range of activities which includes quiz competitions such as “Fill the VOID” where students have to complete some equations which have pieces missing and also “In the BALANCE” where students have to balance equations in order to work out the number of moles on each side of the reaction. This lesson can be used at any time during the year as a revision material, in the lead up to mocks or as a final revision lesson before the GCSE terminal exams.

This extensive revision lesson challenges students on their knowledge and understanding of the content of topics 5 - 8 of the AQA A-level specification. The PowerPoint and accompanying resources are detailed and engaging and contain a selection of tasks which challenge the following points: Directional, stabilising and disruptive selection Saltatory conduction and other factors affecting conductance speed The structure of a motor neurone Sensory receptors, depolarisation and initiation of an action potential Hardy-Weinberg principle Genetic terminology Codominance and sex-linkage Autosomal linkage Chi-squared test Phosphorylation The stages of aerobic respiration Explaining lower ATP yields in anaerobic respiration Skeletal muscle contraction Structure and function of slow and fast twitch muscle fibres The control of heart rate Electrophoresis and genetic fingerprinting The secondary messenger model The students are tested through a variety of tasks including exam questions, understanding checks, and quiz rounds to maintain engagement. Due to the mathematical content in all A-level exams, there is also a focus on these skills. The answers to all questions are embedded into the PowerPoint so students can use this resource outside of the classroom. The delivery of the whole lesson will likely need at least 2 or 3 hours of contact time so this resource could be used with students in the final weeks building up to their paper 2 exam, or alternatively with students before their mocks on these topics.

For example, students are shown how to use the energy change in a chemical reaction to work out if it is an endothermic or exothermic reaction. The topics that are tested within the lesson include: Endothermic and exothermic reactions Reaction profiles Calculating energy changes in reactions Students will be engaged through the numerous activities including a summary round called “E NUMBERS” which requires them to use all of their knowledge to work out the type of reactions that are shown.

This fully-resourced revision lesson consists of an engaging PowerPoint and differentiated resources which together challenge the students on their knowledge of the Key concepts in Physics, which are detailed in topic 1 of the Pearson Edexcel GCSE Physics specification . 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. The following specification points have received a particular focus in this lesson: Motion using speed, velocity and acceleration Speed-time graphs Application of the equations to calculate speed and acceleration Using velocity-time graphs to calculate uniform acceleration and distance travelled Knowledge of the terms reaction time, thinking distance, braking distance and stopping distance The factors which affect these distances A number of quick quiz rounds, such as THE WHOLE DISTANCE, are used to maintain engagement and motivation and to challenge the students on their recall of important points.

There are regular progress checks, with explained answers, so that students can assess their understanding.

This clear and detailed lesson describes the process of oxidative phosphorylation, including the roles of the electron carriers, oxygen and the mitochondrial cristae and explains the role of chemiosmosis. The PowerPoint has been designed to cover points 5.2.2 (g) and (h) of the OCR A-level Biology A specification and includes details of the electron transport chain, proton gradients and ATP synthase. The lesson begins with a discussion about the starting point of the reaction. In the previous stages, the starting molecule was the final product of the last stage but in this stage, it is the reduced coenzymes which release their hydrogen atoms. Moving forwards, the process of oxidative phosphorylation is covered in 7 detailed steps and at each point, key facts are discussed and explored in further detail to enable a deep understanding to be developed. Students will see how the proton gradient across the inner membrane is created and that the flow of protons down the channel associated with ATP synthase results in a conformational change and the addition of phosphate groups to ADP by oxidative phosphorylation. Understanding checks are included throughout the lesson to enable the students to assess their progress and prior knowledge checks allow them to recognise the clear links to other topics and modules. This lesson has been written to tie in with the other uploaded lessons on glycolysis, the Link reaction and Krebs cycle and anaerobic respiration

This fully-resourced lesson looks at the type of circulatory system found in a mammal (double, closed) and considers how the pulmonary circulation differs from the systemic circulation. The engaging PowerPoint and accompanying resources have been designed to cover point 3.1.2 (b) of the OCR A-level Biology A specification The lesson begins with a focus on the meaning of a double circulatory system and checks that students are clear in the understanding that the blood passes through the heart twice per cycle of the body. Beginning with the pulmonary circulation, students will recall that the pulmonary artery carries the blood from the right ventricle to the lungs. An opportunity is taken at this point to check on their knowledge of inhalation and the respiratory system as well as the gas exchange between the alveoli and the capillary bed. A quick quiz is used to introduce arterioles and students will learn that these blood vessels play a crucial role in the changes in blood pressure that prevent the capillaries from damage. When looking at the systemic circulation, time is taken to look at the coronary arteries and renal artery as students have to be aware of these vessels in addition to the ones associated with the heart. In the final part of the lesson, students are challenged to explain how the structure of the heart generates a higher pressure in the systemic circulation and then to explain why the differing pressures are necessary. This lesson has been written to tie in with the other uploaded lessons from topic 3.1.2 (transport in animals)

A highly engaging lesson that looks at the structures that are found in the 1st line of defence and explores the methods of action use by phagocytes and lymphocytes. This lesson has been designed for GCSE students but could be used as an initial recap with A-level students before they go on to learn this topic in greater detail The lesson begins by introducing the meaning of the 1st line of defence. A quick competition is used to challenge the students to recognise the names of some of these structures when their names have some letters missing. Time is taken to discuss the action of the cilia and skin and then students are challenged to make links to the related topics of enzymes and pH as they complete a passage about the role of hydrochloric acid in the stomach. Moving forwards, students will learn that there are two types of white blood cells, phagocytes and lymphocytes, and the details of their actions is explored. Key points such as the specificity of antibodies and the involvement of enzymes are discussed in detail so that this topic can be understood to the depth needed at this level. In addition to a number of games to maintain engagement, progress checks are written into this at regular intervals to allow the students to assess their understanding.

This is a fully-resourced lesson that looks at the meaning of a limiting reactant in a chemical reaction and guides students through how to apply this to a number of calculations. 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. This lesson has been written for GCSE students.

This is a fully-resourced lesson that looks at the functional and structural differences between the transport tissues in a plant, the xylem and phloem. The lesson includes an engaging lesson presentation (41 slides), which includes numerous student-led tasks, progress checks and quick competitions and two question worksheets, one of which is a differentiated version to enable those students who are finding this topic difficult to still be able to access the learning. The lesson begins with the introduction of the two tissues as well as a brief introduction to the substances which they each carry. The next part of the lesson focuses on the xylem cells and the resulting xylem vessel, and key terms such as lignin are brought into the lesson so that students can understand how these cells are waterproofed, which causes them to decay and form hollow tubes. Having met a lot of information, students are challenged to act like an examiner to form a table based question to compare the xylem against the phloem where they have to come up with features which could be compared against. This table will form the backbone of the lesson and students will use it later in the lesson when they have to write summary passages about each of the tissues. Moving forwards, a quick competition is used to enable the students to meet the names of the cells that form the phloem tissue, the sieve tube elements and the companion cells. Students will see how they are involved in the functioning of the phloem and questions are posed which relate to other topics such as the involvement of mitochondria wherever active transport occurs. Progress checks like this are found at regular intervals throughout the lesson so that students can constantly assess their understanding. This lesson has been designed for GCSE students. If you are looking to teach about these tissues but to a higher standard, you could use my uploaded alternative called Xylem and Phloem (A-level)

This fully-resourced lesson looks at the effects of nervous mechanisms on the heart rate. The engaging and detailed PowerPoint and accompanying resources have been designed to cover the part of point 5.1.5 (k) 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 control of the heart rate by the cardiovascular centre in the medulla oblongata This lesson begins with a prior knowledge check where students have to identify and correct any errors in a passage about the conduction system of the heart. This allows the SAN to be recalled as this structure play an important role as the effector in this control system. Moving forwards, the three key parts of a control system are recalled as the next part of the lesson will specifically look at the range of sensory receptors, the coordination centre and the effector. Students are introduced to chemoreceptors and baroreceptors and time is taken to ensure that the understanding of the stimuli detected by these receptors is complete and that they recognise the result is the conduction of an impulse along a neurone to the brain. A quick quiz is used to introduce the medulla oblongata as the location of the cardiovascular centre. The communication between this centre and the SAN through the autonomic nervous system can be poorly understood so detailed explanations are provided and the sympathetic and parasympathetic divisions compared. The final task challenges the students to demonstrate and apply their understanding by writing a detailed description of the control and this task has been differentiated three ways to allow differing abilities to access the work
