Design an overly complicated machine to perform a simple daily task (e.g. taking a photo, waking someone up, feeding your pet, etc.)
As you’re constructing your machine, think about the type of energy involved in processes and the energy transformations (from one type of energy to another, e.g. kinetic/moving energy into sound) and energy transfers (same energy transferred from one object to another, e.g. kinetic energy of a domino into kinetic energy of a ball).
Film your construction working!
