DIN Unit 2: Celestial Sphere/Constellations
Introduction
Unit Two will build upon skills learned in Unit One by teaching students to use star maps, and pre-determined points on the northern horizon to find the North Star. As an alternative, some classes might be able to perform this activity using a planetarium or starlab.
History
In the Northern Hemisphere, the North Star (Polaris), does not appear to move in the night sky. This is why it has had such an important role in ancient myths and legends, as well as in the history of navigation. In the Southern Hemisphere, there are many bright objects that are visible depending on the time of the year.
UnitTwo in Brief
