Describe the Forms of Energy Heat energy (Thermal) Anything that gives off heat Sound energy Anything that gives off sound Kinetic energy Anything that moves Electrical energy Anything that has electricity flowing in it Light energy Anything that gives off light Gravitational potential energy Anything that can fall or is above the ground Strain energy Anything that can be stretched or squeezed Chemical energy Anything that has stored energy in it

Energy Transformation 2) Write down what energy types are given out: 1) Write down the starting energy: Light energy Electrical energy Heat energy

Decide what kind of energy they start with and what kind of energy it is transformed into. 1. It starts with ELECTRICAL and transforms into LIGHT and HEAT 2. It starts with ______________ and transforms into _________ and _______ 3. It starts with stored_____transforms into _______ , ______and ____ when you eat it 4. It starts with stored______ transforms into ______and ____ when you open it

5. It starts with stored________ and 5. It starts with stored________ and transforms into ______and ______ ________ when it flies in the air 6. It starts with stored________ and transforms into ______and _______ when you light it 7. It starts with stored________ and transforms into ______and _________ ________ when it is kicked into the air

How can I improve on task 1? Task 1: Review Go back to your lesson outcome grid and fill out the ‘How I did’ and the ‘Targets’ column. Lesson Outcomes How I did Targets Task 1: Explain some energy transfers. Level 5 Met? Partly met? Not met? How can I improve on task 1?

What’s the link? (Task 2) Explain the link between these 2 pictures. 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 kinetic energy Chemical energy (fuel) light + electrical energy (passenger cabin) Chemical energy (fuel) Thermal + sound energy (engines) 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

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.

How can I improve on task 3? Task 3: Review Go back to your lesson outcome grid and fill out the ‘How I did’ and the ‘Targets’ column. Lesson Outcomes How I did Targets Task 3: Level 7 Met? Partly met? Not met? How can I improve on task 3?
