Hey, this is kind of a dumb question, but what do you guys use to mark your salinometers? Everything I've tried just rubs off.

We just used sharpie, and never had that issue. Just gently dry off the water with a paper towel after you are done using it.

I guess I need new sharpies then, mine have been horribly inconsistent about whether or not they feel like marking the straw. Thanks anyway!

^ This. You have to make sure that the straw has no water on it at all when you're marking it. They're horribly picky about that kind of thing. :lol: It took much trial and error to get mine just right!

My partner and I were wondering if we will be provided with Water Quality Index graphs on the state test to use as a standard of comparison for questions. Thanks! :D

I'm not sure. I saw the graphs on a practice test, but that might have been a practice activity and I don't remember. >.> I didn't get many direct questions that required the graphs. However, it's always good to know the general trends in each section of WQI. If that makes sense.

Typically, the graphs are provided along with the test, but I would put those on your cheat sheet just in case a test writer wants to be evil ;)

Question. Is it just a coincidence, or do all Water Quality Part B tests ask you for Water Quality Index?

Well, it's a key part of it, but on my test, it was only mentioned a couple of times. There was a data table showing the quality of a few bodies of water, and the test-taker had to compare them and answer questions.

My state test had a lot on estuaries, and even had us identifying invasive estuarine species like crabs and fish. I don't think this was supposed to be on there, but we just took our best guesses, and that's what everyone else probably did, too.

Oh, really? I hope there isn't much on estuaries at our state competition. I just know where they are and their importance and stuff like that. :lol:

Hey casey how was the state water quality test? Was there a lot of questions about estuaries on the test, and were there questions regarding invasive plants and where they are from. Thanks. :?:

Looking for a good water quality test (Div. B) to give my students for practice. I've already used all the ones on the test exchange, does anyone have one they could share? I have a bunch of tests I could trade if your interested.

Thanks!

There were actually a couple of estuary questions... One on the percentage of saltwater, and one was a map of something (basically, a world map with the American coasts and European Atlantic coast having a lot of blue marks) where the correct answer was locations of estuaries. There weren't that many macroinvertebrate questions, which is probably why we didn't do as well. We like ID. xD

Hi guys,
What are the topics for Water Quality? I made some really good notes this year, and I want to see if SOME of it will work next year (if they're related).
2012 and 2013: Freshwater/Estuaries
What is 2014's topic?
And will the ecology (part 1) change drastically, or the part 3?
