Also does anyone have an idea on what types of questions we will be asked? I mean I know the topic but I can't find a good practice test because they're all from last year....
Did you team go to any invitationals?

No, we didn't. We're in Maine. Possibly the worst Scio state in the nation.

Double-posting. Ah well..


When calculating distance in Parsecs; SD = ES over Tan1"

For the Sun are we to assume that the distance is a constant and is the distance between the Earth and the Sun?

And could you just explain it in general? Calculating distance is lame... :?

By definition, an object is one parsec away if it has a parallax of one arc-second.
It turns out that one parsec is about equal to 3.2616 light years.

As for how the distance to the sun is determined, I direct you to the wikipedia page on the astronomical unit.

Anyone have any practice questions at all? Besides those on the Scio national website. Just worried I'm missing info. I have images of all the DSO's, solid info on them. But I feel like there;s so much more.

I did quite well with Reach for the Stars for state... but because our high school team needed more people, me being a freshman, I got transferred to that one from my middle school team (where I'm from, my district is bringing both the Div. B and C teams to nationals). I will now work on this for nationals. Seems very different. I'll need WAY more notes, and memorizing constellations and stars doesn't seem to be what this is all about.

You could be asked about constellations for DSOs and other such questions, but otherwise, you're right. The focus is indeed different (as far as I can tell - I never competed in Reach for the Stars, as I've only been in div C). Good luck at nationals!

If you go to the Test Exchange, under Tufts Wright Center, you should find the national tests from when stellar evolution was last a topic.

Here is a link to a thread that contains some good information on the event. I suggest you read through it to get a better idea on the topics and types of questions.
