Nine is not Enough! (planets, that is)

From NSTA:

Astronomers Debate Definition of Planets; Vote Next Week May Raise Number of Planets From 9 to 12

After two years of work a panel convened by the International Astronomical Union has reached a decision about the definition of "planets" and smaller "solar system bodies" such as comets and asteroids. If the definition is approved this week the number of planets in the Solar System would rise from 9 to 12, with more to come. Read more in the USA Today article and an article from the Boston Globe.

What we consider the information or facts of today, may change as our ways of understanding and observing change or develop (or evolve). Since the beginning of time, technological advancements are deemed responsible for these changes and there is obviously no end in sight to this onslaught.

As you decide what to teach students, be sure to also venture beyond content, into the realm of learning... THEIR learning, once they're no longer in your course. What skills and abilities do you want them to take with them so they can inquire and learn more on their own? Do they know how to go about doing this? (It's dangerous to assume they do.)
