During April, the arrangement of the Earth, Moon, and Sun will be such that there will be an eclipse of the Sun at new Moon, and an eclipse of the Moon at full Moon. While viewing both eclipses will be limited geographically and visually, this does provide an opportunity for students to explore the orbital dynamics and positioning necessary for eclipses to occur. Throughout the school year, information and data will be provided through this column so that students can indirectly follow the Earth along its orbital path, the ecliptic, around the Sun. Because from our perspective it is the Sun that is "moving,"students will actually be graphing the Sun's apparent motion caused by the Earth's real orbital and rotational motions.
