A lesson outline created for the Collins Year 7 Scheme of work. (Lesson 4) Learning Objectives Students must be able to show that energy can be useful or non-useful/wasted. (Levels 4-5) Students should be able to illustrate energy transfers using Sankey diagrams (Levels 5-6) You can use the interactive whiteboard to fill in the squares and can create some more of your own interactive questions by duplicating the slides. Worksheet not included, sorry. p.s. theres a couple of mathematical mistakes on slide 7 and 10
