This engaging revision lesson uses a range of tasks to allow students to check their understanding of radioactive decay and nuclear radiation. The PowerPoint and accompanying resources have been designed to challenge the detail of point 4.2 of the AQA GCSE physics and combined science specifications and the following sub-topics are covered: Properties of alpha, beta and gamma Bq as the unit of radioactivity Detecting sources of radiation based on their penetrating power Half-life Decay equations Changes to the mass and charge of the nucleus after decay

This is a fully-resourced lesson which uses exam-style questions, quiz competitions, quick tasks and discussion points to challenge students on their understanding of topics P1 - P4, that will assessed on PAPER 5. It has been specifically designed for students on the AQA 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 received particular attention: The size of an atom The differences between isotopes Using the half-life in calculations The 13 recall and apply equations in topics P1 - P4 Electrical circuit symbols Measuring current using an ammeter Current and potential difference in series and parallel circuits Changes in resistance in resistors Mains domestic supply Kinetic, internal and potential energy in a system Calculating specific heat capacity and latent heat Physical and chemical changes Conservation of energy Calculating gravitational potential and kinetic energy Penetrating abilities of the different types of radiation 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 written into the lesson to walk students through some of the more difficult concepts such as circuit calculations and rearranging formulae and converting between units. Due to the extensiveness of this revision lesson, it is estimated that it will take in excess of 3 or 4 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.

This fully-resourced revision lesson has been written to cover the major details of the radioactivity topic that can be assessed in the GCSE Physics and Combined Science (HT) exams. The engaging PowerPoint and accompanying resources contain a wide range of activities which include exam-style questions with clearly explained answers, differentiated tasks and quiz competitions to allow students to assess their understanding and to ultimately recognise those areas which need further consideration. The following points are covered in this revision lesson: Describe the structure of atom and recall the typical size Recall the relative masses and charges of the subatomic particles and use the number of protons and electrons to explain why atoms are neutral Describe the structure of the nuclei of an isotope Explain what is meant by background radiation and recall sources Describe methods for measuring and detecting radioactivity Describe the process of beta minus and beta plus decay Write and balance nuclear decay equations Explain the effects on the proton and nucleon number as a result of decay Recall that the unit of radioactivity is Bq Use the concept of half-life to carry out calculations Describe the use of isotopes in PET scanners Describe the differences between nuclear fission and fusion Explain how the fission of U-235 produces two daughter nuclei, two or three neutrons and releases energy Write equations to represent nuclear fission Describe the advantages and disadvantages of nuclear energy Explain why nuclear fusion cannot happen at low temperatures and pressures

A quick, concise lesson presentation (15 slides) which together with a question worksheet focuses on ensuring that students can define an isotope and pick these substances out from a selection of substances. The lesson begins by looking at the number of sub-atomic particles in an aluminium atom so that students can recall what is shown by the atomic and mass numbers. This will enable students to calculate the number of protons, neutrons and electrons in three given isotopes and as a result, complete a definition of these substances. The remainder of this short lesson involves 4 application questions where students either have to recognise isotopes from a table or from a diagram and also are asked to write out the formula of an isotope. Ideally this lesson will be taught in conjunction with a lesson on atomic structure.

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.

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 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 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 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.
