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

Moving forwards, students will learn that two isotopes of uranium are involved and will discover and work out how one isotope is changed into the other. Diagrams accompany the theory throughout so that students can visualise how the reaction progresses. They are shown how to work out the two daughter nuclei that are produced in the reaction and how an equation can be written to represent nuclear fission. Progress checks have been written into the lesson at regular intervals so that students can constantly assess their understanding and any misconceptions can be immediately addressed. This lesson has been designed for GCSE students (14 - 16 year olds in the UK)

A fully-resourced lesson which focuses on using the kinetic energy equation to calculate energy, mass and speed. The lesson includes a lesson presentation (23 slides) which guides students through the range of calculations and accompanying worksheets which are differentiated. The lesson begins with the students being drip fed the equation so they are clear on the different factors involved. They are challenged to predict whether increasing the mass or increasing the speed will have a greater effect on the kinetic energy before testing their mathematical skills to get results to support their prediction. Moving forwards, students are shown how to rearrange the equation to make the mass the subject of the formula so they can use their skills when asked to calculate the speed. The final task of the lesson brings all of the learning together to tackle a set of questions of increasing difficulty. These questions have been differentiated so that students who need extra assistance can still access the learning. This lesson has been written for GCSE students
