Bundle of 9 complete No-Prep lessons with exam questions, tasks and answers on Energy for AQA GCSE (9-1) Science / Physics, covering the complete topic (all of AQA 4.1 / 6.1) As a Secondary Science teacher, Deputy Headteacher, writer and examiner for many years I make high quality no-prep lessons so busy teachers can teach outstanding lessons without spending hours planning. These high quality lessons include explanations, different types of in-lesson assessment (all with answers) and unique exam questions. My lessons are ideal for non-Physicists - as a Biologist who retrained as a Physics teacher I know how to take learners on a journey that builds up their understanding step by step, while still going into a lot of depth. The preview videos show a representative sample of slides from each resource so that you get a good idea of what it includes before you buy. Teaching Order Energy Stores and Transfers Kinetic, Elastic and Gravitational Potential Energy Specific Heat Capacity (please note this lesson is also included in the Particle Model of Matter topic bundle). Power (Energy Topic) Useful and Wasted Energy Thermal Conduction and Insulation Efficiency National and Global Energy Resources: Non-Renewables National and Global Energy Resources: Renewables Note: I have not written lessons for the Required Practicals. What’s Included in each lesson: • Starter / Do Now Activity • Explanation slides in “chunked” sections with animated diagrams. • Worked examples of calculations / questions.where applicable • Multiple questions in different question styles and difficulties - no need for worksheets. Each “chunked” explanation section typically includes a set of “learning check / quick questions” followed by a set of in-depth questions on the learning from that “chunk” of the lesson. All questions have answers. • Exam-style questions on the whole lesson at the end of the lesson- these are unique, based on real exam questions but not just copied from exam boards. • Answers for all questions • All easily editable to adapt to your teaching or to use in existing lessons. • Slightly humorous, at points, if you like that sort of thing. The lessons were written for AQA GCSE Science / Physics but are very likely to be applicable to other exam specifications. Please leave a rating / review and all other feedback gratefully received!
