This is a fully-resourced lesson that looks at the reflection of light waves and uses a series of practical based tasks to discover the rules of reflection as well as introducing the critical angle. In addition, students will encounter how total internal reflection can be used in medicine in endoscopy and will be challenged to carry out a task where they act as a doctor to explain to a patient how the procedure works. The lesson contains a variety of tasks, progress checks to check on understanding and a few quick competitions, which introduce key terms. For example, the cover image shows one of these competitions called REFLECT THE WORD where students have to work out the key term - the normal in this case. The understanding of key terminology such as the normal is important so that students can construct ray diagrams in this lesson and in associated topics such as refraction. This lesson has been designed for GCSE aged students but could be used with younger students who are looking to go into this topic in greater depth than perhaps would normally be encountered at their level

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 detailed lesson which looks at the topic of reaction times and guides students through calculating a reaction time using the results of the well known ruler-drop test. In addition, students will see how reaction times can be applied in athletics but also in the calculation of the thinking distance for drivers. The lesson includes an engaging lesson presentation (32 slides) and a student task worksheet. The lesson begins by introducing the key term, reaction time, and teaching students that the average reaction time is 0.2 seconds. Moving forwards, a step by step guide is used to show the students how to take the value for distance travelled by a ruler in the drop test and use the equations of motion and change in velocity equation to calculate the reaction time. There is a large mathematical element to the lesson which challenges the students ability to rearrange formula, convert between units and leave answers to a specified number of significant figures. The answers and methods in obtaining these are always displayed at the end of each task so that the students can assess their understanding and recognise where errors were made if any were. Students will have to follow the provided method to obtain 5 results in the ruler drop test and ultimately find out their own reaction time. The remainder of the lesson looks at how the thinking distance at different speeds can be calculated. This lesson has been written for GCSE students due to the high maths content but could be used with younger students of high ability.

This is a fully-resourced lesson that explores the meaning of irradiation and contamination and challenges the students to make links to the different types of radiation in order to state which type of radiation is most dangerous outside of the body and inside the body. This lesson includes an engaging lesson presentation (28 slides) and a differentiated worksheet which gives assistance to those students who find the task of writing the letter difficult. The lesson has been written to include real life examples to try to make the subject matter more relevant to the students. Therefore, whilst meeting the term contamination, they will briefly read about the incident with Alexander Litvinenko in 2006 to understand how the radiation entered the body. Moving forwards, students will learn that there are examples of consensual contamination such as the injection of an isotope to act as a tracer. At this point of the lesson, links are made to the topic of decay and half-lives and students are challenged to pick an appropriate isotope based on the half-life and then to write a letter to the patient explaining why they made their choice. The remainder of the lesson challenges students to decide which type or types of radiation are most dangerous when an individual is irradiated or contaminated and to explain their answers. This type of progress check can be found throughout the lesson along with a number of quick competitions which act to maintain engagement as well as introduce new terms. This lesson has been written for GCSE aged students

An engaging lesson which uses a range of tasks to ensure that students understand the meaning of the term, background radiation, and are able to name a number of sources of this type of radiation. The start of the lesson focuses on the definition of background radiation and the idea that is all around us is revisited again a number of times during the lesson. Through a range of activities and discussion points, students will meet the different sources as well as the % that they each contribute. It seemed appropriate to challenge some mathematical and scientific skills at this point so students will represent the data in a pie chart form. Related topics are discussed such as Chernobyl. Progress checks are written into the lesson at regular intervals so the students can constantly assess their understanding. This lesson is designed for GCSE students.

A fully-resourced lesson that explores how resistance, current and potential difference differ between series and parallel circuits. This knowledge needs to be sound in order for students to be able to carry out circuit calculations. The lesson includes a practical and task-based lesson presentation (24 slides) and an accompanying worksheet. The lesson begins by challenging the students to recognise the key difference between the two circuits, in that in a parallel circuits, the electrons can follow more than one route. Moving forwards, each physical factor is investigated in each type of circuits and students carry out tasks or calculations to back up any theory given. Helpful analogies and hints are provided to guide the students through this topic which is sometimes poorly understood. Students will be challenged to use the V = IR equation on a number of occasions so that they are comfortable to find out any of these three factors. Progress checks have been written into the lesson at regular intervals so that students are constantly assessing their understanding and any misconceptions can be addressed. This has been written for GCSE students, but could be potentially used with higher ability KS3 students.

This lesson has been designed to help students to explain the relationship between current and resistance in thermistors and LDRs. This can be a topic which students do not engage with or understand well, so this lesson has tried to add engagement with useful tips to deepen their knowledge. A number of quick competitions are used to introduce key terms such as semiconductor and then the key points explained. Students are given an exemplary answer for the thermistor so they can see how their work should be set out when trying to explain the graph produced by a LDR. Progress checks have been written into the lesson at regular intervals so that students can assess their understanding and any misconceptions can be addressed. This lesson has been designed 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.

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 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

A fast paced lesson which focuses on the equation for work done and using this in calculations. The lesson includes a student-led lesson presentation and a question worksheet which together explore the different problems that students can encounter when attempting these questions and therefore acts to eliminate any errors. There is a big mathematical element to the lesson which includes the need to rearrange formula, understand standard form and to convert between units as this is a common task in the latest exams. Students will learn that some questions involve the use of two equations as they are needed to move from a mass to a force (weight) before applying the work done equation. The last part of the lesson looks at how work done is involved in the calculation for power. This lesson has been designed for GCSE students.

A fast-paced lesson that looks at weight and how this differs on different planets depending upon the gravitational field strength. At the start of the lesson, the students are shown the equation to calculate gravity force and weight and are challenged to spot a difference (if there is one)! Time is then taken to explain how weight is the term used when a mass comes into the gravitational field of the Earth (or other planets). A quick understanding check, with the gravitational field strength Olympics, is used to see whether students can calculate this field and their mathematical skills are tested with a number of conversions needed to do so. Moving forwards, students are shown a number of masses and weights on the Earth and the Moon so they can see how mass does not change but weight will be different. The final task challenges them to apply their new-found knowledge to calculate their mass on the Earth, the Moon and Jupiter. This lesson has been designed for GCSE students but it is suitable for KS3 students who are exploring the Universe topic.

A fully-resourced lesson which includes a concise lesson presentation (16 slides) and accompanying worksheet that guides students through the use of the gravitational potential energy equation to calculate energy, mass and height. The lesson begins by challenging students to work out the factors involved in calculating gravitational potential energy having been given a scenario with some balls on shelves. The students will discover that mass and height affect the energy size and that a third factor, gravity constant, is involved. The rest of the lesson focuses on using the equation to calculate energy, mass and height. In terms of the latter, students have to carry out an engaging task to work out the height that three flags have to be hoisted to during a medal ceremony. This lesson has been written for GCSE students.

An informative lesson which guides students through the commonly misunderstood topic of drawing free body diagrams and using them to calculate resultant forces. The lesson begins by ensuring that students understand that force is a vector quantity and therefore arrows in diagrams can be used to show the magnitude and direction. Drawing free body diagrams is poorly understood and therefore time is taken to go through the three key steps in drawing these diagrams. Each of these steps is demonstrated in a number of examples, so students are able to visualise how to construct the diagrams before they are given the opportunity to apply their new-found knowledge. The rest of the lesson focuses on calculating resultant forces when the forces act in the same plane and also when they are at angles to each other. Again, worked examples are shown before students are challenged to apply. Progress checks are written into the lesson at regular intervals so that students can constantly assess their understanding and any misconceptions can be addressed. 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 fast-paced lesson presentation (20 slides) which focuses on the understanding of the scientific term, specific latent heat, and guides students through use of the related equation in energy calculations. This lesson has been written for GCSE students and along with specific heat capacity, these are topics which students regularly say that they do not understand so the aim here has been to embed the key details. The task at the start of the lesson gets students to plot the changing state line for pure water. They have to annotate the line to show the changes in state and then most crucially recognise that when these changes in state occur, there is no change in temperature. Moving forwards, students will meet the additional terms of fusion and vaporisation and then be introduced to the equation. They are reminded that this isn’t an equation that they have to recall, but are expected to apply it and therefore the next few slides focus on the potential difficulties that could be encountered. These include the conversion between units and a mathematical skills check is included at this point so that their ability to move between grams and kilograms and Joules and kiloJoules is tested. Progress checks like this are written into the lesson at regular intervals so the students can constantly assess their understanding.
