A great science project from Science Buddies that examines how ancient peoples navigated without the benefit of a GPS. Find out which stars are important in navigation in the northern and southern hemispheres. The Science Buddies project ideas are set up consistently beginning with an abstract, objective, and introduction, followed by a section on terms, concepts, and questions, bibliography, list of materials and equipment, experimental procedure, suggestions on how to vary the experiment, plus a focus on the sort of careers this experiment might relate to.
