An engaging, practical-based lesson presentation (22 slides), accompanied by a practical worksheet and application questions which together explore how the extension of a spring is related to force according to Hooke’s Law. The lesson begins by introducing the name of the law and looking at the equation which connects the force, extension and spring constant. As spring constant is likely to be a new term to students, time is taken to look at the definition of this key term. Students are given hints throughout the lesson about potential issues to look out for, including the unit of spring constant being N/m when the majority of springs are small enough that their extension will be measured in cm or mm. Moving forwards, students will follow the provided experimental method to carry out the investigation and produce a set of results which can be used to plot the line. The two distinct sections of the line are discussed and the actual words of Hooke’s Law are given and again discussed and considered. The final part of the lesson involves the students being challenged to apply their knowledge of the law to a range of application questions and assessing against the displayed mark scheme. This lesson has been written for GCSE students but can be used with KS3 students who are studying the extension of a spring

A concise lesson presentation (22 slides) and question worksheet, which together focus on the challenge of applying the equations of motion to calculation questions. Students are given this equation on the data sheet in the exam - therefore, this lesson shows them how they will be expected to rearrange in it four ways. For this reason, the start of the lesson revisits the skills involved in rearranging the formula, beginning with simple tasks and building up to those that involve indices as are found in this equation. Once students have practised these skills, they are challenged to answer 4 questions, although 1 is done together with the class to visualise how to set out the working. 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 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 is a fully-resourced lesson that is written for GCSE students and focuses on the calculations associated with the numerous equations that electrical power is found in. The lesson includes a fast-paced lesson presentation and a series of questions on a worksheet which has been differentiated two ways. Over the course of the lesson, the students will meet the different equations which include the factor of electrical power. Their whole range of mathematical skills will be tested, including rearranging the formula, conversion between units and simplifying two equations into one. The understanding of each of these skills and equations is checked through a range of tasks, each of which has a displayed mark scheme and explanation at the end so that students can self-assess their understanding. Students are encouraged to discuss and come up with insightful questions and answers.

This is a fun and engaging lesson that uses a range of quick competitions and tasks to ensure that the students recognisethe electrical symbols for the essential components and can describe the functions for each of these. Competitions such as SNAP and SAY WHAT YOU SEE will introduce the students to the components and their symbols. This lesson has been written for GCSE students and looks to build on what they should know from KS3 - however, it could be used with higher ability students at that level.

This is a fully-resourced lesson that has been written for GCSE students and focuses on the meaning of the term, potential difference, and guides students through using this factor in calculations. A range of student-led tasks will challenge the students to recognise how a voltmeter needs to be set up to measure the potential difference and then gets them to use the readings to calculate other factors. Their mathematical skills will be tested throughout and students will be asked to analyse their answers and study a series circuit to learn the key rule about potential difference in these types of circuits. Progress checks have been written into the lesson at regular intervals so students are constantly assessing their understanding.

This is a fully-resourced lesson that looks at the different parts of the National Grid, specifically focusing on the roles of the step-up and step-down transformers. The lesson includes an informative lesson presentation (25 slides) and a calculations worksheet which challenges the students to apply their mathematical skills to work out why the potential difference is increased and decreased by the transformers. Time has been taken to make links to related topics such as electrical circuits as well as the conservation of energy. Students will recognise that a high current would have led to a lot energy being dissipated to a thermal energy store if step-up transformers weren’t involved and also that decreasing the potential difference before it enters the homes as mains electricity is important to reduce the risk of electrocution. A number of quick competitions are used to introduce key terms or to check on understanding such as ORDER, ORDER which is shown on the cover image where students have to recognise when the parts of the National Grid are finally shown in the correct order. This lesson has been designed for GCSE aged students.

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 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 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
