This revision lesson contains a motivating and engaging powerpoint (67 slides) and associated worksheets which have been designed to challenge student knowledge of the Periodic Table. The lesson involves a wide range of activities which include exam questions with clear answers to allow students to self-assess, quiz competitions and differentiated tasks. The students will enjoy the transitions between the different activities whilst crucially being able to evaluate their understanding of this key topic in Chemistry. Deliberately, the lesson hasn’t been written for any particular exam board or exclusively for Combined Science or Chemistry, but instead it covers the topics which are shown below and this will allow teachers to pick and choose which parts they want to do in a particular lesson. Properties of the alkali metals (group I) Properties of the halogens (group VII) Properties of the noble gases (group 0) Formation of ionic compounds between group I and VII elements Reactivity of the alkali metals and the halogens Displacement reactions of the halogens The transition elements Organisation of the Periodic Table Predicting properties of the unknown or rare elements As the title suggests, the content of this lesson has been written to be GCSE standard and therefore is most suitable for use with 14 - 16 year olds. However, it could be used with younger students who are doing work on the topic and want to challenge themselves

This revision resource contains an engaging and informative PowerPoint (55 slides) and differentiated worksheets that will enable the students to assess their understanding of the topic C9 content of the CIE IGCSE Combined Science specification for examination in June and November 2020 and 2021.

This lesson has been designed to cover the content as detailed in point 2.13 (The structure and function of the nervous system) of the Edexcel GCSE Biology & Combined Science specifications. Consisting of a detailed and engaging PowerPoint (38 slides) and accompanying worksheets, the range of activities will motivate the students whilst ensuring that the content is covered in detail. Students will learn how receptors, sensory neurones, the CNS, motor neurones and effectors are involved in the detection and response to a stimulus. There is a focus on the structure of the sensory and motor neurones and the presence of the myelin sheath in both of these neurones is discussed with relation to the increased speed of conduction. Students will understand that a synapses involve the diffusion of neurotransmitters and allow communication between neurones and they are briefly introduced to relay neurones but these are covered in more detail in the reflexes lesson. Progress checks are included throughout the lesson so that students can assess their understanding of the content and any misconceptions can be addressed whilst quiz competitions, like FROM NUMBERS 2 LETTERS and SAY WHAT YOU SEE, are used to introduce new terms in a fun and memorable way. This lesson has been written for GCSE-aged students who are studying the Edexcel GCSE Biology or Combined Science specifications but can be used with older students who need to know the key details of the nervous system for their A level course before taking it to greater depths

This lesson has been designed to cover the content as detailed in points 7.9 & 7.10 (The importance of homeostasis) of the Edexcel GCSE Biology specification. Consisting of a detailed and engaging PowerPoint and accompanying worksheets, the range of activities will motivate the students whilst ensuring that the content is covered in detail. Students will learn how a constant internal environment is maintained by homeostasis before being introduced to some of the factors which are regulated by these systems. Time is taken to look into osmoregulation and thermoregulation in more detail, so that students can explain that maintenance of the body temperature at the set-point allows enzymes to function at their maximum rate. Progress checks are included throughout the lesson so that students can assess their understanding of the content and any misconceptions can be addressed whilst quiz competitions, like SAY WHAT YOU SEE and YOU DO THE MATH, are used to introduce new terms and important values in a fun and memorable way. This lesson has been written for GCSE-aged students who are studying the Edexcel GCSE Biology specification but can be used with older students who need to recall the idea of homeostasis before taking it to greater depths in their studies.

This fully-resourced lesson has been designed to cover specification points 2.2 (a and b) about chromosomes and their role in mitosis as detailed in topic 2.2 (Cell division and stem cells) of the WJEC GCSE Biology specification. The wide range of activities will engage and motivate the students whilst ensuring that the content is covered in detail. In order for a deep understanding to be achieved, the other stages of the cell cycle (interphase and cytokinesis) are discussed so that students can recognise how th events that happen before and after this form of cell division results in genetically identical cells. A selection of summary questions will challenge the students on their understanding and ability to apply their knowledge to unfamiliar situations with questions about organisms other than humans. The lesson finishes by looking at the functions of mitosis in living organisms. This lesson has been designed for GCSE-aged students studying the WJEC GCSE Biology course but is also suitable for older students who are learning about mitosis and the cell cycle at A-level and need to go back over the key points

This lesson describes and explains the processes of simple diffusion and facilitated diffusion. The PowerPoint and accompanying resources have been designed to cover the first part of specification point 4.2 (a) of the CIE International A-level Biology course and the factors that increase the rate of diffusion are covered along with the limitations imposed by the phospholipid bilayer and the role of channel and carrier proteins. The structure and properties of cell membranes was covered in topic 4.1 so this lesson has been written to include continual references to the content of that lesson. This enables links to be made between the movement across a cell membrane with the concentration gradient, the parts of the membrane that are involved and any features that may increase the rate at which the molecules move. A series of questions about the alveoli are used to demonstrate how a large surface area, a short diffusion distance and the maintenance of a steep concentration gradient will increase the rate of simple diffusion. One of two quick quiz rounds is then used to introduce temperature and size of molecule as two further factors that can affect simple diffusion. The remainder of the lesson focuses on facilitated diffusion and describes how transmembrane proteins are needed to move small, polar or large molecules from a high concentration to a lower concentration across a partially permeable membrane

This is a fast-paced lesson which uses a range of tasks and quick competitions to compare the diagnosis, symptoms and treatment of Diabetes mellitus Type I and II. Students are continually challenged throughout the lesson to build and deepen their knowledge of these conditions and consider how they can be controlled through hormone injections or lifestyle changes. Clear links are made to related topics such as auto-immune diseases and the endocrine system and progress checks have been written into the lesson to allow students to assess their understanding of all of these topics. The final part of the lesson involves the students writing a letter to an individual who has type II, explaining how this diagnosis was done, giving details of the condition and recommending lifestyle changes. This task is differentiated so that students who are finding it difficult can still access the learning. This lesson has been written for A-level students. If you are looking for a lesson for younger students on this topic, then my other upload “Diabetes Type I and II” will be more suitable.

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 cells and related topics as covered in the GCSE Biology and GCSE Combined Science courses. As cells are the building blocks of living organisms, a strong understanding of this topic is critical for the success of a student on these two courses. The following topics are covered in this revision lesson: The key differences between eukaryotic and prokaryotic cells The structure of a bacterial cell Specialised cells The individual functions of the organelles Calculating size Students will be engaged through the range of activities which includes quiz competitions such as “CELL, CELL, CELL” where students have to compete to identify specialised cells from descriptions. 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 lesson has been designed to cover the content of specification point 4.1.2.1 (Chromosomes) and 4.1.2.2 (Mitosis and the cell cycle) of the AQA GCSE Biology and Combined Science course. Cell division is a topic which can cause students a number of problems so this lesson has been designed to ensure that the key details are covered and checked constantly. As well as the understanding and previous knowledge checks, quiz competitions are written into the lesson to maintain engagement and motivation. The lesson begins with the introduction of the term cell cycle and students will learn that the cycle consists of three stages. The key details of each of these stages is covered during the main part of the lesson so that students can meet the specification requirements of being able to describe the main events. Time is allotted for discussion to encourage students to converse about important points such as what happens to the replicated chromosomes during mitosis to enable identical daughter cells to be produced. Opportunities are taken to make links to other topics such as animal and plant cells as students are challenged to recall the functions of some sub-cellular structures. The final part of the lesson involves a series of summary questions which challenges the students to not only recall content but also to apply to unfamiliar organisms and it is not until the final question that they will answer a question about the cell cycle in humans.

This fully-resourced revision lesson challenges the students on their knowledge of the content detailed in topic 1 (Matter) of the OCR GCSE Physics specification. The wide range of activities, which include exam questions with clear explanations, will allow them to assess their understanding of the content and to recognise those areas which require further attention. The lesson has been designed to cover as much of the module as possible but the following specification points have been given particular attention: Recall and apply the equation to calculate density Describe how and why the atomic model has changed over time Describe the atom and recall the typical size Explain the difference in density between different states of matter Describe how mass is conserved when physical changes occur Describe how physical changes differ from chemical changes Define the term specific heat capacity and distinguish between that and specific latent heat Applying the equation to calculate the specific heat capacity Understanding that temperature does not change during changes of state Applying the equation to calculate the specific latent heat Explaining the qualitative relationship between the temperature of a gas and its pressure Applying the equation that links pressure, volume and a constant Explain how doing work on a gas can increase its temperature Explain why pressure in a liquid varies with depth Most of the resources are differentiated to allow students of differing abilities to access the work and be challenged and the PowerPoint guides the students through the range of mathematical skills which are tested in this module

This fully-resourced revision lesson contains a wide range of activities that will challenge the students on their knowledge and understanding of the content detailed in the CORE and SUPPLEMENT sections of topic P2 (Work, energy and power) of the CIE IGCSE Combined Science specification. These activities include exam style questions which will allow the students to assess their progress against the clearly explained answers. There is also a quiz that runs throughout the course of the lesson and this has been designed to maintain engagement and motivation. The following specification points have been covered in this lesson: Recall and use the equation to calculate work done Demonstrate an understanding that work done = energy transferred Understand that an object may have energy due to its motion or position Recall and use the equations to calculate kinetic and gravitational potential energy Recognise the ways that energy is transferred during events and processes Apply the conservation of energy Recall and use the equation to calculate power Distinguish between renewable and non-renewable sources of energy Describe how electricity is obtained from the tides, hydroelectric power and nuclear fission One of the main tasks of the lesson, which challenges the students to apply the law of the conservation of energy, has been differentiated so that differing abilities can access the work

This fully-resourced lesson describes the internal structure of the heart and all of the blood vessels attached to the heart. Both the engaging PowerPoint and accompanying differentiated resources have been designed to cover the 1st part of section A9 as detailed in the CIE International A-level PE specification. The structure of the heart is a topic which was covered in part at GCSE so this lesson has been written to build on that prior knowledge. The main task of the lesson involves students labelling the different structures as they are recalled. Time is taken at different points of the lesson to look at some of the structures and concepts in further detail. For example, students will learn that humans have a double circulatory system, as detailed in point section A10, and that the thicker muscular wall of the left ventricle allows the blood in the systemic circulation to be pumped at a higher pressure than in the pulmonary circulation. Students are also challenged to explain why a hole in the septum would cause health issues for an affected individual and this links back to previous work in unit 1 on energy systems. By the end of the lesson, the students will be able to identify the following structures and describe their individual functions: right and left atria right and left ventricles septum tricuspid and bicuspid valve semi-lunar valves pulmonary artery and pulmonary vein vena cava aorta A number of quiz rounds are used throughout the lesson to introduce key terms in a fun and memorable way before the final round is used as a final check so they can assess whether they can recognise the structures and recall their functions.

This revision resource has been designed to include a range of activities that will engage the students whilst they assess their understanding of the content of topic C12 of the CIE IGCSE Combined Science specification for examination in June and November 2020 and 2021. Exam questions, quick tasks and quiz competitions such as “Are you on FORM” will challenge the students on their recall of the content as well as their ability to apply this knowledge. The lesson was written to cover as much of the content as possible, but the following topics have received particular attention: • The conditions needed for cracking • Alkanes and alkenes as the products of cracking • Alkanes as saturated hydrocarbons with single covalent bonds between their atoms • Alkenes as unsaturated hydrocarbons with one double covalent bond • Testing between saturated and unsaturated hydrocarbons using aqueous bromine solution • The fractional distillation of crude oil • The uses of the fractions This resource contains an engaging PowerPoint (51 slides) and associated worksheets and is ideal for use at the end of this topic or in the lead up to mocks or the actual terminal exams

This revision resource has been designed to include a range of activities that will engage the students whilst they assess their understanding of the content of topic C2 (Experimental techniques) of the CIE IGCSE Combined Science specification for examination in June and November 2020 and 2021. Exam questions, quick tasks and quiz competitions such as “SEPARATE the FACT from the FICTION” will challenge the students on their recall of the content as well as their ability to apply this knowledge. The lesson was written to cover as much of the content as possible, but the following topics have received particular attention: • Simple distillation and fractional distillation Choosing appropriate apparatus Experimental and investigational skills Crystallisation and filtration Paper chromatography Calculating the retention factor This resource contains an engaging PowerPoint (45 slides) and associated worksheets and is ideal for use at the end of this topic or in the lead up to mocks or the actual terminal exams

This lesson resource contains a engaging PowerPoint and accompanying worksheets, all of which have been designed to cover the content of specification point 2.5 (d) on the WJEC GCSE Biology specification. This specification point states that students should know the components of a reflex arc. This lesson builds on the knowledge from the previous lesson on the structure and function of the nervous system (2.5b). The lesson begins by challenging the students to come up with the word reflex having been presented with 5 other synonyms of the word automatic. This leads into a section of discovery and discussion where students are encouraged to consider how a reflex arc can be automatic and rapid despite the fact that the impulse is conducted into the CNS like any other reaction. Students will be introduced to the relay neurone and will learn how this provides a communication between the sensory neurone and the motor neurone and therefore means that these arcs do not involve processing by the brain. Moving forwards, the main task of the lesson challenges the students to write a detailed description of a reflex arc. Assistance is given on the critical section which involves the relay neurone in the spinal cord before they have to use their knowledge of nervous reactions to write a paragraph before and after to complete the description. As a final task, students will have to compare the structure and functions of sensory, motor and relay neurones. Although this lesson has been designed for students studying on WJEC GCSE Biology course, it is also suitable for older students who are studying reflex reactions at A-level and need to recall the main details.

This is a fully-resourced revision lesson which covers the content detailed in the CORE & SUPPLEMENT sections of topics P5 & P6 (Electrical quantities and electric circuits) of the CIE IGCSE Combined Science specification. The engaging PowerPoint and accompanying resources contain a wide range of activities which include exam-style questions with clearly explained answers, differentiated tasks and quiz competitions to allow students to assess their understanding and to ultimately recognise those areas which need further consideration. The following specification points have been given particular attention in this lesson: The electrical symbols that represent the electrical components Describe the differences between series and parallel circuits Recall that a voltmeter is connected in parallel One volt is equal to one joule per coulomb Recall and use the equations that calculate charge, potential difference and power Recall that an ammeter is connected in series Calculate the currents, potential differences and resistances in series and parallel circuits Know the safety function of the fuse Understand that like charges repel and unlike charges attract This lesson has been designed to fall in line with the heavy mathematical content of the Physics specification with a number of calculation tasks and students are guided through the range of skills that they will have to employ

This detailed and engaging lesson describes the basic structure of a mononucleotide and the similarities and differences between DNA and RNA. The PowerPoint and accompanying worksheet containing exam-style questions have been designed to cover points 2.5 (i) & (ii) of the Pearson Edexcel A-level Biology A specification. In topic 1, the students were introduced to a number of monomers and the start of the lesson challenges them to recognise the key term nucleotide when only the letters U, C and T are shown. The next part of the lesson describes the structure of a DNA nucleotide and an RNA nucleotide so that the pentose sugar and the bases adenine, cytosine and guanine can be recognised as similarities whilst deoxyribose and ribose and thymine and uracil are seen as the differences. Time is taken to discuss how a phosphodiester bond is formed between adjacent nucleotides and their prior knowledge and understanding of condensation reactions is tested through a series of questions. Students are then introduced to the purine and pyrimidine bases and this leads into the description of the double-helical structure of DNA and the hydrogen bonds between complementary bases. The final section of the lesson describes the structure of mRNA, tRNA and rRNA and students are challenged to explain why this single stranded polynucleotide is shorter than DNA In addition to the current understanding and prior knowledge checks, a number of quiz rounds have been written into the lesson to introduce key terms in a fun and memorable way and the final round acts as a final check on the structures of DNA and RNA.

This fully-resourced lesson describes the relationship between the structure of the chloroplast and its role as the site of photosynthesis. The engaging PowerPoint and accompanying resources have been designed to cover specification point 5.7 (i) of the Edexcel A-level Biology B course. Students were introduced to the ultrastructure of eukaryotic cells in topic 2 so this lesson has been written to build on that knowledge. A version of the quiz show POINTLESS runs throughout the lesson and this maintains engagement whilst challenging the students to recall the parts of the chloroplast based on a description which is related to their function. The following structures are covered in this lesson: double membrane thylakoids (grana) stroma intergranal lamellae starch grains chloroplast DNA and ribosomes Once each structure has been recalled, a range of activities are used to ensure that key details are understood such as the role of the thylakoid membranes in the light-dependent stage and the importance of ATP and reduced NADP for the Calvin cycle. This lesson has been specifically written to prepare students for the upcoming lessons on the light-dependent stage and light-independent stage

This lesson describes the relationship between the structure and function of a synapse, focusing on acetylcholine as the neurotransmitter. The engaging and detailed PowerPoint and accompanying resources have been designed to cover the content of point 9.5 (iv) of the Edexcel A-level Biology B specification. The lesson begins by using a version of the WALL (as shown in the cover image) which asks the students to group 12 words into three groups of 4. Not only will this challenge their prior knowledge from topics earlier in this topic but it will also lead to the discovery of four of the structures that are found in a synapse. Moving forwards, students are introduced to acetylcholine as the neurotransmitter involved at cholinergic synapses and they will start to add labels to the structures found in the pre-synaptic bulb. Time is taken to focus on certain structures such as the voltage gated channels as these types of channel were met previously when looking at the depolarisation of a neurone. There is plenty of challenge and discovery as students are pushed to explain why organelles like mitochondria would be found in large numbers in the bulb. With this process being a cascade of events, a bullet point format is used to ensure that the key content is taken in by the students and again key points like exocytosis and the action of acetylcholinesterase are discussed further. Understanding checks and prior knowledge checks are included throughout the lesson so that students can not only assess their progress against the current topic but also be challenged to make links to earlier topics.
