This is a fully-resourced lesson that uses a variety of tasks and quick competitions to look at what happens to sound waves when they hit a boundary and how these properties are utilised for numerous functions and appliances. This lesson includes an engaging and informative lesson presentation (32 slides) and a worksheet which is differentiated two ways to enable students who are finding the topic difficult a chance to access the learning. The lesson begins by looking at how sound waves can be reflected and how this is commonly known as an echo. Students are challenged to use a provided equation to calculate a distance by using the time that the echo of a shout takes to be heard in the Grand Canyon. Moving forwards, students will see how this idea of reflection can be used with ultrasound in the imaging of the foetus. At this stage, as the cover image shows, students are challenged to complete a doctor’s letter to an expectant mother who is concerned about the ultrasound procedure. Assistance is given in the form of a differentiated worksheet for those who find it difficult. Moving forwards, students will learn that sound waves can be refracted at a boundary, just as light waves can. Working with the teacher, they will use key terms to build up an exemplar definition to explain how this refraction occurs. This lesson has been designed for GCSE aged students.

This is a fully-resourced lesson that guides students through the range of calculations involved in calculating speeds in everyday situations. This lesson includes an informative lesson presentation (27 slides) and a question worksheet which has been differentiated two ways. The lesson begins by showing the students a speed camera and challenging them to recall the equation that would be used to calculate the speed as well as asking them to explain where the distance and the time values would come from. This lesson has a high mathematical element to it, to run in line with the questions that were seen in the latest exams this summer. Students will be expected to convert between units and rearrange formula. In this example, students are challenged to convert between m/s and mph in order to determine which of three drivers will receive a speeding ticket for exceeding the limit. This task has been differentiated so that students who find the conversions difficult are given some assistance so they can still access the learning. Moving forwards, students will see how a sensor on a tyre of a bicycle can also be used to calculate the speed by working out the circumference of the tyre to determine the distance. The final part of the lesson gets students to convert between m/s and mph and the other way to find out some typical speeds of everyday motion such as walking, running or a train moving. This lesson has been written for GCSE aged students but could be used with younger students of high ability who need an extra challenge in the calculating speed topic.

This is a fully-resourced lesson that looks at the role of transformers in the National Grid, explains why they increase or decrease potential difference and then uses the given equation to calculate potential difference or the number of turns on the primary or secondary coil. This lesson includes an informative lesson presentation (25 slides) and two question worksheets. The lesson begins by introducing the devices that are transformers and showing the students that there are two types, step-up and step-down. Students will learn that step-up transformers increase the potential difference and step-down transformers decrease the potential difference. Moving forwards, a series of calculations are used to get the students to understand why these changes in potential difference occur. Students are guided through this section so that they are able to complete a summary passage about the roles of these devices. They will then be shown the equation connecting potential difference and number of turns which they do not need to recall but have to apply. Again, a worked example is used to visualise how workings should be set out before students are challenged to answer two sets of questions, the second of which involves the use of a second equation. Progress checks like these are found at regular intervals throughout the lesson so that students can assess their understanding. This lesson has been written for GCSE students

This is a fully-resourced lesson that looks at how pressure can be calculated using force and area and then explores how hydraulics are used to transmit a force through a fluid and challenges the students to apply the given equation to calculate the force or area. The lesson includes a lesson presentation (18 slides) and a question worksheet which has been differentiated two ways. The lesson begins by challenging the students to use an answer to a calculation question to work out the equation that links pressure, force and area. A range of mathematical skills are tested throughout the lesson, such as converting between units and rearranging formula, and then the answers are fully explained so any student who was unable to move through the question can visualise the method. Moving forwards, students will be introduced to a hydraulics system and the equation which they will be given on the sheet in the exam. Students will use the equation to calculate the force or area at the second point of the system. This task has been differentiated so that students who find it difficult are still able to access the learning. This lesson has been written for GCSE aged students

Students will enjoy the range of activities which includes quiz competitions such as “FILL THE VOID” where students compete to be the 1st to complete one of the 12 recall equations in this topic. This lesson is suitable to be used as a revision resource at the end of the topic or in the lead up to mocks or the actual GCSE exams

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.

This fully-resourced revision lesson covers the CORE and SUPPLEMENT sections of topic P4 (Properties of waves, including light and sound) of the CIE IGCSE Combined Science specification. The engaging PowerPoint and acccompanying resource have been written to include a wide range of activities which include exam-style questions (with clearly explained answers), differentiated tasks and quick quiz competitions. These activities challenge the following specification points: State the meaning of speed, frequency, wavelength and amplitude Distinguish between transverse and longitudinal waves and give examples Describe how waves can undergo reflection and refraction and that the latter is caused by a change in the wave speed Recall and use the law of reflection Describe the main features of the EM spectrum State that all waves travel at the speed of light in a vacuum and recall this speed Describe the uses of the EM waves Describe the longitudinal nature of sound waves Recall and use the equation to calculate wave speed Describe how to measure the speed of sound in air and ripples on water surfaces Recall that sound waves can be ultrasound To fall in line with the greater mathematical content of the specification, there is a large emphasis on a range of mathematical skills in this lesson which includes the use of standard form. Due to the detail of this lesson, it is estimated that it will take in excess of 2 hours of IGCSE-allocated teaching time to cover the content and this allows this to be used at the end of the topic or in the lead up to mock or terminal examinations.

This is a fully-resourced lesson which uses exam-style questions, engaging quiz competitions, quick tasks and discussion points to challenge students on their understanding of the content of topics P1 - P6, that will assessed on PAPER 5. It has been specifically designed for students on the 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 cover as many specification points as possible but the following sub-topics have been given particular attention: Factors affecting thinking and braking distance The 7 recall and apply equations tested in PAPER 5 The units associated with the physical factors challenged in PAPER 5 Recognising the motions represented by different motions on velocity-time graphs Using a velocity-time graph to calculate acceleration Resultant forces Sound waves as longitudinal waves The electromagnetic waves Using significant figures and standard form The relative charges and masses of the particles in an atom Recognising isotopes Using the half-life of radioactive isotopes The development of the atomic model 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 extra support when they are unable to begin a question. Step-by-step guides have also been incorporated into the lesson to walk through students through some of the more difficult concepts such as half-life calculations. 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 course as well as acting as a final revision before the PAPER 5 exam.
