And yet It still moves

Galileo.

There are 63 known moons orbiting our gas giant planet Jupiter. Galileo could only see four of them. They're now called Galilean moons (Io, Europa, Ganymede and Callisto, to be more specific).



EXTRA CREDIT


In celebration of Galileo and Jupiter (it's the closest to Earth it's been for 50 years and won't get this close again for 75 years) I offer the following extra credit assignment. For five consecutive nights you'll need to be an amateur astronomer. Sit comfortably with a pair of binoculars or telescope and look at Jupiter. Then draw the Jupiter and the positions of it's Galilean moons each of the five nights. Finally, write two paragraphs: one about the moons themselves; the other about your experience with this assignment.


It's worth up to 20 points--depending on the quality of your work. This assignment does have an expiration date [it wraps up--due on my desk--by 7:45 am, Tuesday, October 5].
