H3.
A total lunar eclipse is observed on December 31. Predict the next lunar eclipse. A total lunar eclipse will occur when the full moon and the nominal orbit of the moon line up together (The solution of two equations). From the following data algebraic equation for the phase of the moon and nominal orbit of the moon can be formed. A new moon (0%) was observed on December 17 and the full moon (10%) was observed on December 31 along with the nominal orbit of the moon (0%). The brimming orbit of the moon (100%) was observed on November 29. When the two equations are equal a lunar eclipse will occur.
How many days from December 31 will next lunar eclipse occur? Given the coming year is a leap year - on what dates will the next 4 total lunar eclipses occur?

O What research question is the student investigating?
A. How long does it take Earth to rotate on its axis?
B. Does the moon rotate at a faster rate than Earth does?
C. How do the locations of the stars relate to the moon?
D. What is the relationship between time of day and seeing objects in
the sky?
7. Suppose you are on a strange planet and observe, at night, that the stars do not rise and set, but circle parallel
to the horizon. Next, you walk in a constant direction for 8000 miles, and at your new location on the planet,
you find that all stars rise straight up in the east and set straight down in the west, perpendicular to the horizon.
How could you determine the circumference of the planet without any further observations? What is the
circumference, in miles, of the planet? [OER Chapter 2, Figuring for Yourself #43]
