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 detailed lesson presentation (37 slides) that looks at the different motions that are represented on a velocity-time graph and guides students through using these graphs to calculate the distance travelled by an object. The lesson begins by challenging the students to construct a velocity-time graph by using a displayed guide and using their knowledge of drawing a distance-time graph. Moving forwards, the students will match terms of motion to the lines on the graph and time is taken to make links to the physics equations that allow acceleration and deceleration to be calculated. Students will also learn that they can use a velocity-time graph to calculate the distance travelled. A worked example is used to show them how to tackle these questions. There are regular progress checks throughout the lesson so that students can assess their understanding of this topic. This lesson has been designed for GCSE students but could be used with higher ability KS3 students

A fully resourced lesson which guides students through writing decay equations to represent alpha and beta decay. This lesson includes a lesson presentation (41 slides) and differentiated worksheets. Time is taken at the beginning of the lesson to ensure that students know the sub-atomic particles that are found in an alpha particle and a beta particle so that they can understand why the atomic and mass numbers are affected during the decay. Moving forwards, a step-by-step guide is used to show students how to write both types of equations. There are regular progress checks throughout the lesson so that students can check their understanding. This lesson has been written for GCSE students (14 - 16 year olds in the UK)

This is a fully-resourced revision lesson that could be used over a series of lessons to help students to revise and assess their knowledge of the content in topics P1 (Matter), P2 (Forces) and P3 (Electricity and magnetism) of the OCR Gateway A GCSE Combined Science specifiction which can be assessed in paper 5. This revision lesson uses a combination of exam questions, understanding checks, quick tasks and quiz competitions to cover the following sub-topics and specification points: Describe how and why the atomic model has changed over time Describe the structure of the atom and the charges of the particles Define the term specific latent heat Conversions from non S.I. units to S.I. units Explain the vector-scalar distinction Recall examples in which objects interact Represent forces as vectors by drawing free-body diagrams Know the definition of Newton’s three laws of motion Define momentum and describe examples of momentum in collisions Recall and apply Newton’s third law Describe the relationship between force and the extension of a spring Calculate the spring constant in linear cases Define mass and weight Recall that current depends upon both potential difference and resistance Recall and apply the relationship between I, R and V Show that Fleming’s left hand rule represents the relative orientations of current, magnetic field and force This lesson contains a big emphasis on the mathematical calculations that will be involved in these exams, and as a result students are challenged to recall the equations and to apply them. Students will be engaged through the numerous quiz rounds whilst crucially being able to recognise those areas which require their further attention during general revision or during the lead up to the actual GCSE terminal exams. A lot of the tasks have been differentiated so that students of all abilities can access the work and be challenged appropriately.

This fully-resourced revision lesson challenges the students on their knowledge of the content detailed in topic 3 (Particle model of matter) of the AQA GCSE Physics specification. The wide range of activities which include exam questions with clear explanations will allow them to assess their understanding of the content and to recognise those areas which require further attention. The lesson has been designed to cover as much of the topic as possible but the following specification points have been given particular attention: Recall and apply the equation to calculate density Explaining differences in density between states of matter Internal energy and the result of heating the particles in a system Applying the equation to calculate the specific heat capacity Understanding that temperature does not change during changes of state Applying the equation to calculate the specific latent heat Explaining the qualitative relationship between the temperature of a gas and its pressure Applying the equation that links pressure, volume and a constant The engaging PowerPoint guides students on the use of key mathematical skills to aid success with the various calculations

This is a fully-resourced revision lesson that has been written to include a wide range of activities that challenge the students on their knowledge of astrophysics as detailed in topic 8 of the Pearson Edexcel IGCSE Physics specification. The numerous quiz rounds which include “Shine a LIGHT on any ERRORS” will engage and motivate their students whilst they assess their understanding of the content and recognise any areas that require further attention. The lesson has been designed to include as many of the specification points as possible but the following have been given particular attention: Understanding of the terms Solar system, galaxy and universe Gravitational field strength varies on different planets Gravitational force causes the Moon to orbit the Earth and the planets to orbit the Sun Use the relationship between orbital speed, orbital radius and time period Evolution of stars of a similar mass to our Sun and of stars with larger masses The evidence that supports the Big Bang theory The change in the frequency and wavelength of a wave if the source of the wave is moving in relation to the observer Red-shift as evidence of an expanding universe This topic contains a number of principles or theories which can be poorly understood by students so extra time has been taken to guide them in the formation of descriptions and explanations.

This is an engaging revision lesson which uses a range of exam questions, understanding checks, quiz tasks and quiz competitions to enable students to assess their understanding of the content within topic 3 (Properties of waves, including light and sound) of the Cambridge IGCSE Physics (0625) specification. The lesson covers the content in both the core and supplement sections of the specification and therefore can be used with students who will be taking the extended papers as well as the core papers. The specification points that are covered in this revision lesson include: Give the meaning of the terms speed, frequency, wavelength and amplitude Distinguish between longitudinal and transverse waves and be able to give suitable examples of each Recall and use the equation velocity = frequency x wavelength Describe how waves can undergo reflection, refraction and diffraction Describe how wavelength affects diffraction Describe an experimental demonstration of the refraction of light Be able to define refractive index and recall the equation to calculate Give the meaning of the critical angle and recall the equation to calculate Describe total internal reflection and be able to explain the use of optical fibres in medicine The electromagnetic spectrum Describe the longitudinal nature of sound waves State the approximate range of audible frequencies for a healthy human Show an understanding of the term ultrasound Describe an experiment to determine the speed of sound in air The students will thoroughly enjoy the range of activities, which include quiz competitions such as “Should you WAVE goodbye” where they have to decide if a passage is 100% factually correct or not whilst crucially being able to recognise the areas of this topic which 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 GCSE exams.

This engaging and detailed lesson presentation (43 slides) uses a step by step guide to take students through the important scientific skill of drawing graphs to represent data and address all the misconceptions and misunderstandings that often accompany this topic. The lesson begins by explaining to the students how to decide whether data should be represented on a line graph or a bar chart and a competition called "To BAR or not to BAR" is used to allow them to check their understanding while maintaining motivation. Moving forwards, students are shown a 6 step guide to drawing a line graph. Included along the way are graphs that are wrong and explanations as to why so that students can see what to avoid. There are continuous progress checks and a homework is also included as part of the lesson. This lesson is written for students of all ages who are studying Science.

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 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
