This is an engaging REVISION lesson which is fully-resourced and 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 Pearson Edexcel IGCSE Physics 9-1 specification (4PH1) for first teaching in 2017 and first assessment in June 2019. The specification points that are covered and challenged in this revision lesson include: Use the following units: ampere (A), coulomb ©, joule (J), ohm (Ω), second (s), volt (V) and watt (W) understand how the use of fuses protects the device or user in a range of domestic appliances Know and use the relationship between power, current and voltage Know the difference between mains electricity being alternating current (a.c.) and direct current (d.c.) being supplied by a cell or battery Understand how the current in a series circuit depends on the applied voltage and the number and nature of other components Know and use the relationship between voltage, current and resistance Know that current is the rate of flow of charge Know that electric current in solid metallic conductors is a flow of negatively charged electrons Know that the voltage across two components connected in parallel is the same Calculate the currents, voltages and resistances of two resistive components connected in a series circuit Explain how positive and negative electrostatic charges are produced on materials by the loss and gain of electrons Know that there are forces of attraction between unlike charges and forces of repulsion between like charges The students will thoroughly enjoy the range of activities, which include quiz competitions such as “COMPLETE ME” where they have to compete to be the 1st to recognise an electrical key term to complete a passage 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 International GCSE exams

An engaging lesson presentation (30 slides) that looks at electric current and ensures that students know the key details about this factor in preparation for their GCSE studies. The lesson begins by forming a definition for this electrical term and then as the lesson progresses, this definition is broken so that each element is understood. Students will be introduced to the difference between electron flow and conventional current. Time is taken to ensure that students understand that an ammeter must be set up in series. The remainder of the lesson will focus on the mathematical calculations which include current and important skills such as converting between units is covered.] As stated above, this lesson has been designed primarily for those students taking their GCSE exams (14 - 16 year olds in the UK) but is suitable for younger students too.

A fully-resourced lesson that looks at the meaning of thinking, braking and stopping distances and focuses on the factors that would cause each of them to increase. The lesson includes an engaging lesson presentation (45 slides) and an associated worksheet for the calculations. The lesson begins by introducing the term stopping distance and then challenging students to recognise that both the distance travelled during the driver’s reaction time and under the braking force will contribute to this. Students are constantly challenged to think about the factors that would cause either the thinking or braking distance to increase and to be able to explain why scientifically. Moving forwards, the mathematical element that is associated with this topic is explored as students are shown how to calculate the braking distance at different speeds as well as convert between speeds in miles per hour and metres per second. There is also a set homework included as part of the lesson. There are regular progress checks written into the lesson so that students can assess their understanding. This lesson has been written for GCSE students but could be used with those at KS3.

This lesson has been designed to explore the range of energy sources which are used on Earth and specifically looks at why an increase in the use of renewable sources is critical for the future. The student’s scientific understanding is challenged at each step of the lesson but there is also a mathematical element running throughout. The lesson begins by challenging the students to predict which energy sources contributed the greatest % when presented with a pie chart. Students cover this topic in other subjects like Geography, so the lesson aims to build on this and consolidate the essential understanding. A range of renewable sources are discussed and key terms such as carbon-neutral taken on further. This lesson has been designed for GCSE students but parts could be used with younger students who are looking at

A concise, fast-paced lesson that looks at the orbits of both natural and artifical satellites. The lesson has been written to build on the student’s knowledge of space from KS3 and add key details such as the gravitational pull between the different celestial objects. Students will learn how the speed of the orbiting object and the gravitational pull ensure that the object remains in orbit and consider what would happen should the speed change. Students are briefly introduced to a number of orbits of artificial satellites as well as the uses. This lesson has been designed for GCSE students

An engaging lesson presentation that looks at how the amplitude and frequency of a sound wave can change. The lesson uses a range of sounds from recordings and challenges the students to draw the sound waves that would have been produced. In order to understand this topic, it is essential that the key terminology is understood and can be used in the correct context. Therefore, the start of the lesson focuses on wavelength and frequency and then longitudinal and challenges the students to recognise that these could all be related to sound waves. Moving forwards, students will hear a recording and then read a music “critique” that uses the key terminology so that can link the sounds to the change in shape of the waves. The final part of the lesson involves them drawing how the different sound waves would change from the control one. This lesson has been designed for GCSE students.

A fast-paced lesson where the main focus is the description of motion with reference to the forces involved. The lesson begins by introducing the term, terminal velocity, and then through consideration of examples in the English language, students will understand that this is the top velocity. The example of a skydiver is used and whilst the story of the dive is told, students are challenged to draw a sketch graph to show the different stages of this journey. An exemplary answer is used to visualise how the motion should be described. Related topics like free body diagrams and resultant forces are brought into the answer in an attempt to demonstrate how they are all interlinked. The next task asks the students to try to describe the remaining parts of the graph and they can assess against displayed mark schemes. The final part of the lesson looks at the two terminal velocities that they were during the skydive and explains that the increased surface area after the parachute was opened led to the second velocity being lower. The last task challenges the students to use this knowledge to answer a difficult exam question. It has been differentiated so those students who need extra assistance can still access the learning. This lesson has been written for GCSE students.

A fully-resourced lesson that includes a detailed and engaging lesson presentation (33 slides) and question worksheets which are diifferentiated. Together these resources guide students through the tricky topic of the conservation of energy by transfers between energy stores which can often be poorly understood. This lesson has been written for GCSE students, but the law can be taught from an earlier age so this would be suitable for higher ability KS3 lessons. The lesson begins by introducing the key term, energy stores. The understanding of this term is critical for this topic and other lessons on energy transfers and therefore some time is taken to ensure that this key points are embedded into the lesson. Students will learn that stores can be calculated due to the fact that they have an equation associated with them and some of these need to be recalled (or applied) at GCSE. Therefore, the first part of the lesson involves two engaging competitions where students are challenged to recall part of an energy store equation or to recognise which energy store an equation is associated with. Students are given the information about the remaining energy stores, such as chemical and electrostatic. Moving forwards, the main part of the lesson explores the law of the conservation of energy and shows students how they need to be able to apply this law to calculation questions. Students are shown how to answer an example question involving the transfer of energy from a gravity store to a kinetic energy store. A lot of important discussion points come up in this calculation, such as resistive forces and the dissipation of energy, so these are given the attention they need. Students are then challenged to apply their knowledge to a calculation question on their own - this task has been differentiated two ways so that all students can access the learning. The final slide of the lesson looks at the different ways that energy can be transferred between stores but those are covered in detail in separate lessons.
