How much will we need to know about orbit, rotation, seasons, weather patterns, air pressure, and how that all fits together?
Yes, all of those things were on the practice test...
So thats basiccaly what we need to prepare for, that sounds easy

What we need to prepare for is in the rules....

If you're talking about here on Earth, then, yes. Rules say "seasons, tides, lunar and solar eclipses, lunar and planetary phases".

Also, do we have to know the North stars? (for precession)

I think north stars a bit specific...
but you could def. study it just in case...
I would study everything important first, and then worry about little details later...

I think this test focuses only on what is in OUR solar system.

They mean the north stars of each planet in our solar system, like Polaris is our north star.

No, I meant precession for earth. You know, where the north pole makes a circle every 26000 years, and we have different north stars (Polaris (a Ursae Minoris), b Ursae Minoris, Thuban (a Draconis), and Vega (a Lyrae)).

Oh, never mind. It just says "planetary motion including rotation, revolution, and precession". So I guess EAST is right. But what the north star be for Uranus? The Sun?

Do you have the rule book yet?

Precession may not be of importance except as it relates to Earth. You will need to be able to identify the constellations containing all planets visible on the evening of the day of the competition, either with the unaided eye or a telescope, however.

Process skills are what will be important, i.e., generating inferences, making predictions, problem solving, making and recording observations, formulating and evaluating hypotheses, interpreting data, graphing, etc.

I encourage you to watch the PowerPoint on the sonic.org site. It is quite informative, and will answer many of your questions, especially if you have not yet seen the rules.

Yes, I already have the rule book and have already seen the PowerPoint. I was confused because the rules didn't specify which planet(s) precession applied to, while I would assume you would need to know rotation and revolution for all planets.
