Conservation of Energy & Sankey Explorer, Year 9
Students adjust input energy and efficiency across a light bulb, motor, car engine, solar panel, kettle and bouncing ball, with a Sankey diagram whose arrow widths show where the energy goes and a live check that input equals useful plus wasted energy. The full interactive is available to licensed Education Universe users.
