Maybe rather than clay, try to use something that doesn't change it's shape very easily. Like I think that when the clay's shape changes, your salinometer de-calabrates... So yea. Just find something that isn't as.. soft? as clay.Sorry if someone's already asked this, but does anyone have salinometer tips? I've just been doing the straw and clay thing, but I feel like that's not gonna cut it for nationals. Is there a way to make a more precise salinometer? I have trouble making accurate straw ones.
Erm. If they do have real macros, I doubt that they will have you guys looking through microscopes because the macros can be visible with just your eyes. Also, I think the best way you could possibly practice is just take a bunch of different tests. Also, if they have them out, try to find a Nationals test from like last year or something. Good luck!Ok: Pros at Water Quality: What do you think the Nationals test will look like? For example, if there are 100 questions, how many of the question will be on part 1, 2, and 3. In addition, for part one (my weakest part) how many questions do you think will be allotted for each subject? Lastly, do you think they'll have REAL PRESERVED Macroinvertebrates that we'll have to see with a microscope? If so, do you know where I can buy some to practice?
THANK YOU! I really want to do well !
I haven't even had a test that needed those graphs. *facepalm* But yeah, I've had practice tests that have given them, so I'd imagine that they wouldn't make you memorize everything for nationals.I would expect them to do so. So far, I haven't seen a test that doesn't give you the charts.Do you guys know if the charts for water quality index are given at nats?
