At a science club in Aqaba, pupils build a simple model cart. They study the wheels, which help the cart move, and a small battery that powers a safe motor. The teacher explains the difference between an invention and a discovery. An invention is something people design, while a discovery adds to what people know about the world. The pupils ask questions before they change the model. One group keeps a record of each test so they can compare results. Their first design does not work well, but they do not hide the problem. They use their notes to decide what to improve next.
