Estuaries, in this event, are a separate topic from freshwater regardless of their definition. So while they can be freshwater in some cases, we don't need to know about them for Water Quality.

Oof. The first 5 questions on the test at my most recent invitational were regarding estuaries

Shouldn't this event be under lab since you have to build something as well as take a test?

But the test and ID portion count for 2/3 of the event and the build only counts for 1/3.
I know stuff about rocks, minerals, experiments, and ecosystems, yay!
Now I kind of know stuff about amphibians, reptiles, fossils, and water... hopefully I'll get to keep learning.

I'm pretty sure the salinometer counts for 5% of the score.

The manual says that each part of the competition counts for 1/3 of the score, but then it says that salinity testing counts for 5%.

Part III should be worth approximately 1/3 of the score. Part III includes a number items, including the salinometer, which should be worth 5% of the total score by itself. The remainder of the Part III points (to reach ~33%) should come from questions on Part III paragraph d topics.

you could just start with a simple clay and straw salinometer, You can find lots of them online, or you could go complicated with an electrical one with circuits and stuff which you can also find plans for online.

I personally succ at making the straw and clay one, but if you spend more than 5 minutes on making it then it's typically reasonably consistent.

Hi I'm completely new to Scioly so I have no idea how these events work. Someone mentioned we have to build a salinity tester??? Like physically build one? and how????

Yes, for this event you have to build a salinometer (although iirc it only counts for 5% of your grade). You can find instructions on how to build a basic one on the wiki page here: Water Quality Wiki. You can probably also find plans for a more accurate one online and work from there.

In a Water Quality test, there was a question stating that the condition in which DO is below 1 mg and no life that requires oxygen can be supported is
called stagnation. The other answer choices were hypoxia, bioaccumulation, and apoxia.
Can someone explain why the answer isn't hypoxia, but stagnation?
Thanks.

I think (?) it should be hypoxia

Oof I was just issued that test today as well. I was looking at the other test keys from the same school and BOY OH BOY. There was more red pen on the keys than the actual tests. As Name said, the key can be wrong at times.
