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 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

A fully-resourced lesson which looks at speed and velocity as scalar and vector quantities and then guides students through a range of questions which challenge them to calculate both of these forms of motion. The lesson includes an engaging lesson presentation (44 slides) and differentiated worksheets containing questions. The lesson begins by introducing the terms magnitude and direction so that students can learn how scalar and vector quantities differ. Students will learn that speed is a scalar quantity and velocity is a vector quantity and then be questioned through a crossroads scenario to understand how speed can stay the same but as soon as an object changes direction, the velocity changes. Moving forwards, the students are given the equation to calculate speed and a few simple questions are worked through before they have to do a series of their own questions to find the average speeds for walking, running and cycling. A pair of more difficult speed questions are then attempted which challenge the students to convert from metres per seconds to miles per hour and to calculate the speed of a bicycle by calculating the distance travelled by the sensor on the wheel. This task is differentiated so that students who need some assistance will still be able to access the work. A quiz competition is then used to introduce students to the range of equations which contain velocity and then having been given them, they have to rearrange the formula to make velocity the subject and apply to some further questions. The final task of the lesson brings all the work together in one final competition where students have to use their new-found knowledge of speed and velocity to get TEAM POINTS. Progress checks have been written into the lesson at regular intervals to allow the students to check their understanding and any misconceptions to be addressed immediately. This lesson has been written for GCSE students and links between the other topics on the curriculum but could be used with KS3 students who are finding the topic of speed too simple and are needing a challenge
