Lesson: Sankey Diagrams Physics

Students will be able to

• interpret and draw Sankey diagrams that represent energy processes,
• recall that since energy cannot be created or destroyed, a Sankey diagram must not gain or lose width along its path,
• make calculations of how much energy is used or wasted and calculations of efficiency given the energy value for one or more branches of a Sankey diagram,
• recognize when a Sankey diagram shows a process that is physically impossible.
