It starts with stored________ and transforms into ______and _________ ________ when it is kicked into the air Task 1: Review Go back to your lesson outcome grid and fill out the ‘How I did’ and the ‘Targets’ column. Lesson Outcomes Task 1: Explain some energy transfers. Level 5 How I did Met? Partly met? Not met? Targets How can I improve on task 1? What’s the link? (Task 2) Discuss in pairs • Explain the link between these 2 pictures. Identify the energy in action (Output Energy) & energy stored in an object (Input Energy). (Task 2) In book ENERGY IN ACTION (Task 2) KINETIC ENERGY SOUND ENERGY ELECTRICAL ENERGY HEAT & LIGHT ENERGY STORED ENERGY GRAVITATIONAL POTENTIAL ENERGY CHEMICAL ENERGY STRAIN ENERGY NUCLEAR ENERGY Energy Transformation Device Input energy Output energy Dynamo kinetic electrical Solar cell light electrical Catapult elastic kinetic Bulb electrical light Energy Transformation Device Input energy Output energy Microphone sound Loudspeaker electrical sound Pendulum gravitational kinetic Motor electrical kinetic electrical Task 2: Review Go back to your lesson outcome grid and fill out the ‘How I did’ and the ‘Targets’ column. Lesson Outcomes Task 2: Explain how energy may be stored. Level 6 How I did Met? Partly met? Not met? Targets How can I improve on task 2? Energy light + electrical energy (passenger cabin) Chemical energy (fuel) CONSERVATION OF ENERGY Energy can never be created or destroyed. It can only be converted from one form into another. elastic energy (tyres) Gravitational potential energy Thermal + sound energy (engines) Conservation Of Energy • Energy cannot be created or destroyed. It is transferred from one type into another. • Therefore, whatever amount of energy an object starts with, it must end up with the same. New Information for Task 3 • Apply your knowledge of Transformation of Energy to the things happening around you. • Give two examples and explain the energy transformation in detail. Task 3: Review Go back to your lesson outcome grid and fill out the ‘How I did’ and the ‘Targets’ column. Lesson Outcomes Task 3: Level 7 How I did Met? Partly met? Not met? Targets How can I improve on task 3?
