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 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
