This activity highlights the navigational challenges in determining longitude from time measurements. Students build their own longitude clock that visualises in a simple way how to determine longitude via time measurements. They practise basic math, understanding the underlying fundamental concept, and they get an insight into the historic events that led to the invention of the first maritime timekeeper, following the steps of James Cook’s second voyage around the world.
