Re: New York 2013

Does anyone know how the team numbering system works for States? Like, which regions winners get which states team numbers?

Re: Water Quality B/C

Thanks! Another question, sorry about being so spam-ish Is there a difference between a deer fly and a horse fly? The rules say deer/horse fly, does it mean there is a distinction between them or just different names for the same thing? This might help you http://ohioline.osu.edu/hyg-fact/2000/2115...

Re: Water Quality B/C

For the classic straw+clay salinometer, isn't that based on the buoyancy? So if the beaker sized was different at competition vs at home when we calibrated it, wouldn't that affect the accuracy of our salinometer? Remember, you can bring your own beaker, if you want. To be honest, while there is a ...

Re: Chem Lab C

Does anyone have any good tests or know where to find a good test that has both periodicity and electrochemistry? I've checked the SciOly test exchange, and none of the tests there are both periodicity and electrochem. Thanks in advance

Re: Forestry B/C

Thanks!

@Fellow new yorkers, is there a good way to tell Scarlet Oak and Pin Oak apart by their leaves and/or acorns?
