Through a series of simple body movements, students gain insight into the relationship between time and astronomical motions of Earth (rotation about its axis, and orbit around the Sun), and also about how these motions influence what we see in the sky at various times of the day and year. A lunation is equal to 29 days, 12 hours, and 44 minutes. latin word for "sea."
