Ranking Task: Lunar Phases with Geometrical View

This ranking task presents a simplified representation of the Earth and lunar orbit and asks the student to order the figures based on the cyclical phases beginning at a randomly determined starting phase, and proceeding either chronologically or reverse chronologically. This ranking task can be contrasted against the "RT_LunarPhases" ranking task, where the phases are ranked based on a view from Earth instead of a "third-person" perspective.
