Suppose you were stranded on a desert island without a calendar or clock. How would you know when a day, a month, or a year had passed? The sun is a great method to figure out time. Wherever the sun is at is what time it is. 2. How could you tell what time of year it was? The moon and its phases Gizmo Warm-up Thousands of years ago, people told time by looking at the sky. You may not think about it, but you probably do this as well. For example, you know a day has passed when the Sun rises, it grows light outside, and then the Sun sets again. In the Seasons: Earth, Moon, and Sun Gizmo, you will learn how you can relate the passage of time to different astronomical events. Drag the Simulation speed slider all the way to the left.
