Well..... I mean, I may be wrong, but that means the proctors were extremely erm... off, with the test. Salinometer testing is in the national rules...

Yep, 3c in the rules says teams must build and demonstrate their salinometer at the competition. Don't let bad supervisors sway you; you'll need the salinometer for State!

At most of our invites and at regionals the proctors didn't even make us wear goggles, thank goodness. I know state will probably require us to put them on.

"The points for this testing should be approximately 5% of the total score (e.g., if a team recorded between 6.0-7.0%, they could receive 5 points out of 100)." This is under Rule Clarifications on soinc.org.

So basically, the salinometers aren't a large part it your final score. I'm not putting too much effort on it, just making sure I can get my results within the 1% range. And we didn't use salinometers or goggles at regionals either. Salinometers will most likely be required for states.

Actually we had to test our salinometer in regionals.. They gave us a tank of water and we had to get a sample and tell the supervisor the percentage. So yes, they are using it this year.

Any good websites you can study from other than soinc.org?
Thanks

For matching, if something was supposed to be nymph, but you put it down as larvae, will that be counted as wrong? Even if you got the organism right?

just put the organism down. Unless they tell you too I wouldn't differentiate between that just because the grader might not know what they're doing or you might put nymph instead of larva. this is what I've always done.

oh kay! I mean we have googles, salinometer and calculators as it says in the requirements... but it is really annoying that we spend time on it but we never use it. Well, states next week in Maryland, and I'll bring it so we can win States for the 1st time in Frederick County.

Does anyone know if the saltwater that we need to measure is NaCl?
