Answer 1

-There is one station on rocks and minerals- 2 rocks, 1 mineral (they'll be really easy because they can only ask you for observable qualities) You won't have to identify them but for the rocks you have to write what type of rock(igneous, metamorphic, sedimentary) and how you can tell.  For the minerals you have to check off whether it is metallic or not, cleaves or fractures, is harder or softer than glass, and what color streak it makes.

-There will be a station on finding the epicenter of an earthquake by using triangulation- you have to use your compass and find the distance to the epicenter by finding the time difference between P and S-waves

-There will be a station on constructing ellipses and measuring the eccentricity and at least in my case, comparing it to the eccentricity of a planet.

I took the practical today and it's really easy.  I freaked out and studied really hard, but truthfully, your biggest problem will probably stupid mistakes.  9 minutes is a lot of time even though it doesn't seem like it when you're preparing.  I had extra time left after each station.

Good Luck!
