This is a fully-resourced lesson that looks at the role of transformers in the National Grid, explains why they increase or decrease potential difference and then uses the given equation to calculate potential difference or the number of turns on the primary or secondary coil. This lesson includes an informative lesson presentation (25 slides) and two question worksheets. The lesson begins by introducing the devices that are transformers and showing the students that there are two types, step-up and step-down. Students will learn that step-up transformers increase the potential difference and step-down transformers decrease the potential difference. Moving forwards, a series of calculations are used to get the students to understand why these changes in potential difference occur. Students are guided through this section so that they are able to complete a summary passage about the roles of these devices. They will then be shown the equation connecting potential difference and number of turns which they do not need to recall but have to apply. Again, a worked example is used to visualise how workings should be set out before students are challenged to answer two sets of questions, the second of which involves the use of a second equation. Progress checks like these are found at regular intervals throughout the lesson so that students can assess their understanding. This lesson has been written for GCSE students

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

This lesson can be used as revision resource at the end of the topic or in the lead up to mocks or the actual International GCSE exams

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.

An engaging lesson presentation (28 slides) and accompanying worksheet, which together look at how to calculate efficiency and explores how efficiency can be increased by reducing the ways that energy is transferred to less useful stores. The lesson begins by looking at the key term, dissipated, and ensuring that students understand that energy being dissipated to a thermal energy store is one of the main reasons why efficiency will be low. Moving forwards, students are introduced to the equation to calculate efficiency and shown how to leave the answer as a decimal or percentage. Mathematical skills are challenged when calculating the efficiency as a number of units have to be converted. The rest of the lesson looks at a range of methods that can be used to reduce losses. Students will work with the teacher to understand how lubrication works and then a homework task gets them to explore how insulation in homes reduces heat losses. This lesson has been designed for GCSE students.

This lesson has been designed to explore the range of energy sources which are used on Earth and specifically looks at why an increase in the use of renewable sources is critical for the future. The student’s scientific understanding is challenged at each step of the lesson but there is also a mathematical element running throughout. The lesson begins by challenging the students to predict which energy sources contributed the greatest % when presented with a pie chart. Students cover this topic in other subjects like Geography, so the lesson aims to build on this and consolidate the essential understanding. A range of renewable sources are discussed and key terms such as carbon-neutral taken on further. This lesson has been designed for GCSE students but parts could be used with younger students who are looking at

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 concise, fast-paced lesson that looks at the orbits of both natural and artifical satellites. The lesson has been written to build on the student’s knowledge of space from KS3 and add key details such as the gravitational pull between the different celestial objects. Students will learn how the speed of the orbiting object and the gravitational pull ensure that the object remains in orbit and consider what would happen should the speed change. Students are briefly introduced to a number of orbits of artificial satellites as well as the uses. This lesson has been designed for GCSE students

This lesson has been written for GCSE students and aims to ensure that they can explain in detail why light changes direction due to refraction. The key to the explanation is the use of the correct terms in context so the start of the lesson challenges the students to come up with the key words of light, bend, normal, density and speed when given a range of clues. The next part of the lesson works with the students to bring these key terms together to form a definition of refraction. Moving forwards, the relationship between density of a medium and the speed of light through that medium is discussed so that there is a clear understanding of why light bends one way or the other. The next task uses the definition to apply to a practical situation to draw a diagram of light moving from air to glass. The final part of the lesson involves a range of practicals so this topic can be explored further.

A fully resourced lesson which includes an informative lesson presentation (25 slides) and an associated worksheet that show students how to give answers to a certain number of significant figures. The answers to questions in Science are often required to be given in significant figures and this lesson guides students through this process, including the rules of rounding that must be applied for success to be likely. This lesson has been designed for GCSE students but is suitable for KS3

An engaging lesson presentation (30 slides) that looks at electric current and ensures that students know the key details about this factor in preparation for their GCSE studies. The lesson begins by forming a definition for this electrical term and then as the lesson progresses, this definition is broken so that each element is understood. Students will be introduced to the difference between electron flow and conventional current. Time is taken to ensure that students understand that an ammeter must be set up in series. The remainder of the lesson will focus on the mathematical calculations which include current and important skills such as converting between units is covered.] As stated above, this lesson has been designed primarily for those students taking their GCSE exams (14 - 16 year olds in the UK) but is suitable for younger students too.

This revision lesson challenges students to explain the results of an osmosis investigation and to calculate accelerations using 2 equations. The PowerPoint and accompanying resources have been designed to check on the understanding of these two topics as detailed in the AQA GCSE biology, physics and combined specifications. The lesson contains a range of tasks including worked examples, exam questions and quizzes which will remind students that water molecules move across partially permeable membranes by osmosis and how changes in the mass of a potato can be used to compare water concentrations in the potato and solution. Students will also recall that acceleration can be calculated from velocity-time graphs using change in velocity/time as well as through the use of F=ma.
