  • Challenge Question #4

    Challenge Question #4

    We noticed that classes #3 and #6 had not reached an equal amount of sunlight
    and darkness yet. We brainstormed ideas of why this might be. Perhaps the data
    was incorrect, but probably not. Since we know that the earth wobbles on its
    axis due to the moon’s gravitational pull on the earth, maybe those classes did
    not achieve the equinox on March 20 because on that particular day they were
    wobbled onto a position that received less light.
