In this program, students investigate the possibility that the ancient ruins of Stonehenge could have been used by its builders as a gigantic astronomical observatory and calendar. By actively formulating and testing their own hypotheses in the planetarium, the students learn how astronomer Gerald Hawkins went about discovering Stonehenge's probable function. Along the way, they learn a lot about apparent stellar, solar, and lunar motion. Classroom activities include making a Solar Motion Demonstrator and recording sunrise/sunset positions.
