Demonstrate understanding of a complex machine
You need to choose a complex machine (something like a lawnmower, drill, or escalator that has an engine or motor powering it) and explain how it works. You'll describe what the main parts do, use proper technical language and diagrams, and discuss how efficiently it uses its energy. The key is understanding not just what the machine does, but *why* it's designed that way and how well it performs.
You correctly identify the main components and their functions, explain how the machine works using some technical language and diagrams, and discuss energy efficiency in basic terms.
You explain in detail how the components work together to achieve the machine's purpose, you evaluate whether it's energy efficient and why, and your diagrams and language are clearly technical and accurate.
You discuss specific, realistic ways to improve the energy efficiency and justify why each change would work, showing deep understanding of how the design choices affect both function and energy use.
