Problem I  The Moons of Jupiter  Relative Sizes  Students will use fractions to compare the sizes of several of Jupiter's moons. [ Open PDF ] Problem II  The Relative Sizes of the Jovian Moons.  The moon Europa is 3/5 the diameter of Ganymede, and Io is 6/5 the diameter of Europa. How big is Io compared to Ganymede? [Answer: 3/5 x 6/5 = 18/25] Explain your thinking: Write your own problem  Using information found in the Math Connection problems, the press release or the video program, create your own math problem. Explain why you set the problem up this way, and how you might find its answer. Evaluate your understanding: Challenge Problem: The Moons of Jupiter  Orbital Synchrony  Students work with the orbit periods of several of Jupiter's moons and determine through the use of simple fractions when the periods of the moons match up.
