Alongside the “properties of waves” lesson, this lesson is also designed to be fast-paced with a focus on the key terminology of the waves topic as well as looking at the different calculations that can be carried out. It is written for GCSE students and challenges their mathematical skills throughout, by asking them to rearrange formulae, convert units and write in standard form. The lesson begins by recalling the definitions for wavelength, frequency and wave velocity and then introducing them to the equation that links them. The velocity of sound waves in three mediums is the initial focus, so that students can recognise that the velocity is higher in liquids and solids than in air. Moving forwards, the concept of an echo is discussed and again a calculation used to show them how distance could be worked out with the added extra of the final division by 2. There are progress checks such as these written throughout the lesson so that students have the opportunity to assess their understanding. A number of quick competitions are also included, in order to maintain engagement whilst check understanding in a different form.

This is a concise, fast-paced lesson designed to cover the key terminology associated with the waves topic at GCSE and ensure that students are able to recognise and use these terms in context. A number of terms, such a transverse, are known by students but rarely correctly used in written descriptions. Therefore, through a range of tasks and quick competitions, students will meet these terms, learn how to define them and then be asked to apply their knowledge to understanding check questions. This lesson has been written in conjuction with the lesson titled “Wave velocity” and students are challenged to keep an A - Z of key terms during both lessons so they can challenge themselves during revision points.

A fast-paced lesson which includes an informative lesson presentation (20 slides) and a question worksheet. Together these resources guide GCSE students through the calculation questions that they can encounter on the topic of the conservation of momentum. The lesson begins by introducing the law of the conservation of momentum and reminding students of the equation which links momentum, mass and velocity that they are expected to recall for the GCSE exam. Time is taken to inform them of the two types of question which tend to arise on this topic - those where the masses lock together during the event and those where they remain as separate masses. Students are guided through both of these types of questions with worked examples to enable them to visualise how to begin and set out their workings. Key mathematical skills are involved such as rearranging the formula so this is also shown. Students are given the opportunity to apply these skills to a series of questions on the worksheet and the mark schemes are displayed so they can assess once completed.

A short, concise lesson presentation (25 slides) that explores the key evidence that is used to support the Big Bang Theory. This lesson has been written for GCSE students with the focus on the fine details which they need to be able to understand in order to successfully answer exam questions on this topic. The lesson begins with a fun slide which challenges their mathematical skills to work out a number of years and spot that a dingbat represents the Big Bang. This leads students into the key details of the theory and includes when it was believed to have happened. The rest of the lesson focuses on two main pieces of evidence, namely red shift and CMBR. Students are guided through these topics and related topics such as the Doppler effect are revisited. The final part of the lesson uses a quick competition to get students to recognise the names of alternative theories and a set homework challenges them to add details in terms of evidence to support each of steady state and creationism.

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.

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.

An engaging and informative lesson presentation (49 slides) looks at the differences between contact and non-contact forces and focuses on enabling students to describe and recognise them. This lesson has been written for GCSE students but could be used in higher ability KS3 lessons with students who are looking to progress their knowledge. The lesson begins by introducing the fact that forces can be grouped into these two categories and initial definitions are used to ease the students into the lesson. To follow on from this a competition called “FORCE it together” is used. This engaging game challenges the students to spot the name of a force which is in anagram form and then once it has been identified, they have to determine whether it would be a contact or non-contact force. As each force is met, key details are given and discussed. More time is given to areas which can cause problems for students, such as the use of weight and gravity force and whether they are actually different. Moving forwards, a rugby tackle is used to show the numerous forces that interact in everyday situations, before students are challenged to identify more forces in sports of their choice. Students will recall/learn that force is a vector quantity and therefore is represented in diagrams using arrows. Once again, this lesson focuses on showing them how these arrows can be used differently with the different types of forces. Students are briefly introduced to the idea of a free body diagram and an understanding check is used to see whether they can identify friction, gravity force and normal contact force from the arrows. Progress checks like this are written into the lesson at regular intervals, in a range of formats, so that students are constantly assessing their understanding. The final part of the lesson is one more quick competition where students have to use their knowledge of the forces to form words.

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.
