Re: Water Quality B/C
What the heck wasup with the division b water quality test?? It was so hard!!!! This is my best event I study everything and then it becomes the hardest event ever at States!!! Then we have to use the Salim nometer and got 7th percent!!! I'm freaking out because I got 7th place out of 20 teams!!!! Ahhh!!

Re: Water Quality B/C
Division C test wasn't that easy either, especially with the multiple choice. The multiple choice seemed way harder than the short answer.sazhassan wrote:What the heck wasup with the division b water quality test?? It was so hard!!!!

Re: Water Quality B/C
At my competition, we had solutions of 10%, 5%, and 1.5%. They were at least around there, because I don't know if we got them right.silentsage wrote: Does anyone think that proctors are scared to make a solution below 3% or above 8%? I've never encountered any higher.

My partner said Division C and B were the same except for one question. Wq is my best event, I got 7th. ;(cngu23 wrote:Division C test wasn't that easy either, especially with the multiple choice.

Re: Water Quality B/C
Any in depth bug questions? I hope it focuses more on the other sections, its water quality, not entomology!!!!. lol sorry, i just hate the bug part.

Re: Water Quality B/C
I love the bugs, but my Regional WQ had none. I find the bugs to be really easy once studied, and life is the most important indicator of water quality, so sorry, there has to be identification.jfang1234 wrote:Any in depth bug questions?

Road Scholar seems to depress everyone on my team who does it, but it's my favorite event...

Re: Water Quality B/C
The problem we have found seems to be with the clay. It can dry out, change shape slightly, not seal correctly, absorb water. What I have found to be more accurate is to use different materials that are impermeable to water. I have had much more accuracy using a pipette or plastic syringe. The bulb part at the bottom I filled completely with sand (if you do not fill it completely, the air pocket will make the salinometer tip to the sides). Then, because my pipette was not long enough to keep the top above water, I plugged it with some clay and cut a straw in half and pushed the straw onto the pipette. I then taped over the edge of where the straw connects to the plastic pipette. I then started with my 0% solution and marked the line, then I mixed a 10% solution and marked the line. Then using my ruler I made a line that was 1/2 way in-between and then just experimented with eyeballing the other 4 lines in between 0 & 5 and 5 & 10 to make them equally spaced. I have tested this salinometer with other % solutions and it seems to be fairly accurate now. Here is a link of what the plastic pipette looks like (ask your science teacher if they have some!) and I used a larger straw that seemed to fit snugly. I cut the tip of the pipette somewhat to be able to pour the sand in. Hope this is helpful.

Re: Water Quality B/C
I am new to Water Quality, and had a question on the salinometer. When they ask for say a 5% salinity, is it 5 grams of salt and 95 grams of water? Or is it 5 grams of salt and 100 grams of water? Also, what salt will they be using? Non-Iodized Table Salt? Thanks in advance...

Re: Water Quality B/C
It seems like this was confusing for a lot of people. Earlier in the thread, someone posted the answer to that question and an official rules clarification. Good luck!FlyingMonkey85 wrote:I am new to Water Quality, and had a question on the salinometer. When they ask for say a 5% salinity, is it 5 grams of salt and 95 grams of water?
