Problem I  Exploring Saturn's Moons  Although astronomers usually measure distances to a planet's satellites in multiples of the planet's radius, in this problem, we work with the distance given as a decimal fraction of the orbit distance to a planet's farthest known satellite. [Open PDF] Problem II  Exploring Saturn's Moons  Orbit Periods  The moons of Saturn orbit the planet in time periods from hours to years. In this problem, students will organize a list of orbit periods from shortest to longest using decimal comparisons. [Open PDF] 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 distances of each moon from Saturn can be written in units of millions of kilometers so that '18.5' equals 18.5 million kilometers. Can you answer questions about the moon distances in terms of these decimal numbers? [Open PDF]
